Prostate cancer is the second most diagnosed cancer in men worldwide and a significant cause of cancer-related death. Proteogenomic analysis offers insights into how genomic mutations influence protein expression and can identify novel biomarkers. This study aimed to investigate the impact of missense mutations on protein abundance in prostate cancer versus healthy tissues using SILAC-based quantitative proteomics.

Mass spectrometry data from prostate tumors and adjacent healthy tissues were analyzed using stable isotope labeling. Peptides were classified based on their abundance into RefSeq and Variant Abundant groups. Missense mutations were mapped via RefSeq and dbPepVar databases. Protein intensity metrics were compared, and Spearman’s correlation was used to evaluate the relationship between mutation presence and protein abundance.

Functional enrichment revealed that RefSeq Abundant proteins are involved in normal metabolic and structural functions, while Variant Abundant proteins are enriched in tumor-related pathways such as immune evasion and apoptosis suppression. A significant negative correlation was found between protein intensity difference and ratio (p < 0.05), indicating that missense mutations contribute to altered protein expression. Mutation hotspot analysis identified recurrent alterations in genes such as PPIF and ACTB. PROVEAN was used to evaluate the functional impact of variants, identifying several as deleterious to protein stability and function.

Missense mutations are associated with altered protein abundance and may promote oncogenic processes in prostate cancer. These findings enhance the understanding of genome-proteome interactions and could support the development of targeted biomarkers and therapies.

To observe the clinical efficacy of Jiawei Lizhong Tang combined with dorsal Yu acupoint embedding in patients with non-alcoholic steatohepatitis (NASH).

A total of 118 patients with NASH who attended the Department of Gastroenterology at Liuzhou Hospital of Traditional Chinese Medicine from January 2020 to December 2022 were selected as study subjects. The participants were randomly assigned to either the control group or the observation group using a random number table, with 59 cases in each group. The control group received treatment with Western medicine (compound glycyrrhizin capsule), whereas the observation group received treatment with traditional Chinese medicine combined with thread embedding (Jiawei Lizhong Tang combined with dorsal Yu acupoints embedding). Both groups received a treatment course of 12 weeks. The following anthropometric indicators were measured: weight, waist circumference, and body mass index. Liver function was assessed by measuring alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), and total bilirubin (TBIL). Lipid profile indicators included triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Blood glucose indicators included fasting blood glucose, fasting insulin (FINS), and insulin resistance index (HOMA-IR). Additionally, liver stiffness measurement (LSM), controlled attenuation parameter (CAP), and liver/spleen CT ratio were assessed. Clinical efficacy was evaluated at the end of the treatment period.

After 12 weeks of treatment, significant improvements were observed in weight, waist circumference, BMI, serum ALT, AST, GGT, TBil, TG, TC, LDL-C, HDL-C, fasting glucose, FINS, HOMA-IR, LSM, CAP, and liver/spleen CT ratio in both groups compared to baseline (P<0.05). The improvements in these indicators were significantly better in the observation group than in the control group after treatment (P<0.05).

The treatment of NASH with Jiawei Lizhong Tang combined with dorsal Yu acupoint embedding effectively improves patient condition, reduces liver function damage, regulates blood lipids, insulin resistance, and hepatic steatosis. The therapeutic effect is superior to that of Western medicine therapy.

Reprogramming of lipid metabolism has emerged as a significant characteristic of malignancy during tumor development. Research indicates a critical link between lipid metabolism and the tumor immune microenvironment. This relationship not only facilitates cancer progression by remodeling the tumor microenvironment but also influences the functionality of immune cells. Alterations in lipid metabolism regulate the function and status of immune cells within the microenvironment, impacting immune evasion and the therapeutic efficacy of tumors. Consequently, targeting lipid metabolism is a viable strategy for intervening in tumorigenesis and tumor development. This review examines the roles of key lipid molecules, such as fatty acids and cholesterol, within the tumor microenvironment, highlighting how aberrant lipid metabolism can alter immune cell function. By investigating the interactions between lipid metabolism and immune cells in this setting, the review offers novel insights into early diagnosis, screening, and immunotherapy of malignant tumors. Furthermore, lipid metabolic reprogramming may act as a biomarker for monitoring early immune escape from tumors and predicting therapeutic outcomes, thereby enhancing early diagnosis and personalized cancer treatment.

Endometrial cancer (EC) is one of the most prevalent malignancies of the female reproductive system and ranks among the three primary types of gynecological cancers. Recent trends indicate a rising incidence of EC in younger patients, highlighting the urgent need for effective early screening strategies. This review examines the challenges associated with early diagnosis and screening, including ambiguous methodologies (e.g., transvaginal ultrasound: sensitivity 80–90%, specificity 60–70%), undefined target populations, and the absence of efficient, cost-effective, minimally invasive solutions (e.g., cytology sensitivity ≤50% in community settings). The article provides an overview of the current landscape and emerging innovations in universal EC screening, highlighting advancements in early detection and diagnosis, such as DNA methylation panels (sensitivity 89–94%, specificity 91–97% in phase II trials) and vibrational spectroscopy (sensitivity 92%, specificity 88% in pilot studies). Additionally, future directions for implementing effective screening strategies are explored, emphasizing the potential of high-accuracy biomarkers and scalable technologies to reduce mortality and healthcare costs.

Breast cancer remains one of the leading causes of cancer-related deaths worldwide. Early detection of breast cancer significantly improves outcomes and survival rates, minimizing treatments. Imaging techniques are critical in identifying abnormalities and diagnosing breast cancer at its earliest stages, often before clinical symptoms emerge. Mammography remains standard for screening in average-risk women, while supplementary methods like ultrasound, magnetic resonance imaging, and tomosynthesis enhance detection rates, particularly in women with dense breasts or those at high risk. Given that certain factors, such as family history, age, genetic mutations, and breast density, affect the risk of developing breast cancer, some women may benefit from earlier or more frequent screenings. Personalized screening protocols are becoming more common, tailoring the type and frequency of imaging to the individual’s risk profile. Newer technologies, such as molecular breast imaging and contrast-enhanced mammography show promise but require further validation for widespread use. In conclusion, imaging techniques including mammography, ultrasound, magnetic resonance imaging, and newer technologies like three-dimensional mammography and molecular breast imaging are essential tools in the early detection of breast cancer, leading to better outcomes for patients. This literature review provides an overview of current breast cancer imaging methods, their role in early diagnosis, and their effectiveness and limitations.

Emergency department (ED) presentations are associated with higher cancer mortality. This study aimed to investigate the prevalence, frequency, and risk factors in Australian patients diagnosed with malignant skin cancers.

This data-linkage cohort study examined adult patients presenting to the ED at the Royal Melbourne and Western Health hospitals within 12 months of a malignant skin cancer diagnosis. Multivariable logistic and Poisson regressions were used to analyze factors influencing the prevalence and frequency of ED presentations.

A total of 3,873 patients were diagnosed with skin malignancies between 2010 and 2018, of which 631 were diagnosed with melanoma. The prevalence of ED presentation was 29%, representing 2,119 episodes of care (median: 0; range: 0–14). Risk factors for a higher prevalence and frequency included: age ≥75 years (odds ratio (OR) = 1.78 [95% confidence interval 1.47–2.15]; incidence risk ratio (IRR) = 1.52 [1.35–1.70]); male (OR = 1.17 [1.01–1.36]; IRR = 1.23 [1.12–1.35]); socioeconomic status levels of 0–30% (OR = 1.59 [1.24–2.03]; IRR = 1.69 [1.45–1.96]) and 71–100% (OR = 1.30 [1.07–1.58]; IRR = 1.27 [1.12–1.45]); preferred language other than English (OR = 1.47 [1.17–1.84]; IRR = 1.49 [1.32–1.69]); and experience with any systemic therapy or radiotherapy (OR = 3.77 [2.12–6.71]; IRR = 2.36 [1.82–3.05]). Age < 65 years was protective (OR = 0.72 [0.59–0.89]; IRR = 0.78 [0.68–0.90]). Other preferred languages and cancer treatment experience were also risk factors in the sub-cohort with melanoma.

This study reports the prevalence and frequency of ED presentations following a skin cancer diagnosis and their association with socioeconomic and linguistic factors in Australia. Increased awareness of these factors could help address health inequities and potentially reduce the need for ED presentations.

In recent years, it has been found that Lycium barbarum can repair liver damage and promote liver regeneration. Additionally, the polysaccharides contained in Lycium barbarum have anticancer properties and can induce apoptosis in cancer cells. Molecular docking, a mature computer-aided method, is widely used in drug discovery. This study aimed to verify the efficacy of active ingredients of Lycium barbarum in the treatment of liver cancer by molecular docking.

The effect of the active ingredients of Lycium barbarum in the treatment of liver cancer was verified by molecular docking, based on a previous study that examined the impact of Lycium barbarum on liver cancer using network pharmacology.

The binding energies of the key active ingredients and core targets were all less than −5.0 kcal/mol (1 kcal = 4.184 J), with most of them being less than −7.0 kcal/mol. This indicates that the key active ingredients and core targets have good binding ability, with most demonstrating strong binding affinity.

Most of the active ingredients in wolfberry can spontaneously bind to the core target protein, thereby playing a therapeutic role in liver cancer.

Mitochondria are highly dynamic organelles that adapt to cellular stress and metabolic demands through processes such as fission, fusion, mitophagy, and transport, all of which are vital for maintaining cellular signaling and metabolic homeostasis. Fission facilitates mitochondrial division and biogenesis, while fusion enhances mitochondrial fitness and metabolic flexibility by mitigating damage. Together, these processes play a critical role in regulating cellular stress responses and apoptosis. Dysregulation of mitochondrial dynamics has been linked to impaired development and cancer progression, including breast cancer metastasis. A comprehensive understanding of mitochondrial dynamics in breast cancer progression is essential for advancing precision medicine. This review delves into the intricate molecular mechanisms governing mitochondrial biogenesis, fission, fusion, and mitophagy, with a particular focus on the role of mitophagy in maintaining mitochondrial homeostasis and its connection to metastasis progression. Furthermore, it discusses potential therapeutic strategies targeting mitochondrial dynamics and highlights the critical steps necessary to translate these approaches into clinical trials.

Huo Xue Tong Luo Capsule (HXTL) has been clinically used to treat osteonecrosis of the femoral head, osteoporosis, and other bone and joint diseases with promising effects. Our previous study has shown that HXTL can promote osteogenesis in mesenchymal stem cells by inhibiting lncRNA-Miat expression through histone modifications. However, the mechanism by which HXTL treats postmenopausal osteoporosis (PMOP) remains unclear. In this study, we used network pharmacology-based mechanism prediction, molecular docking, and pharmacological validation to investigate the mechanism of HXTL in treating PMOP.

The key candidate targets and relevant signaling pathways of HXTL for PMOP treatment were predicted using network pharmacology and molecular docking analysis. RAW264.7 cells were used for Western blot to validate the predicted mechanistic pathways. The ovaries of mice were surgically removed to simulate PMOP. The effect of HXTL on PMOP was evaluated using tartrate-resistant acid phosphatase staining and immunohistochemical assays in vivo.

Network pharmacology analysis suggested that HXTL interacted with 215 key targets linked to PMOP, primarily affecting the PI3K-AKT signaling pathway. Molecular docking showed that the main components of HXTL exhibited strong binding affinity to NFATc1, p-PI3K, and p-AKT1. Furthermore, our in vitro results confirmed that HXTL suppressed the PI3K-AKT signaling pathway. In vivo, HE and tartrate-resistant acid phosphatase staining results showed that HXTL inhibited osteoclast formation and protected bone mass.

This research demonstrated that HXTL could inhibit osteoclast formation and prevent bone loss induced by ovariectomy in mice by inhibiting the PI3K-AKT signaling pathway. These findings provide important evidence for the clinical application of HXTL in treating PMOP.

Cancer is the leading cause of death globally, with nearly 20 million new cases and 9.7 million deaths in 2022. Due to its vague initial symptoms, cancer is often difficult to detect in its early stages. Liquid biopsy, a revolutionary approach in oncology, provides a minimally invasive, real-time method for cancer detection, monitoring, and characterization by examining circulating tumor components in body fluids. This review presents current technologies and clinical applications of liquid biopsy, focusing particularly on its value for early cancer diagnosis. Liquid biopsy enables molecular profiling of cancer for precision oncology by isolating circulating extracellular nucleic acids (cell-free DNA), circulating tumor DNA, and circulating tumor cells from blood and other body fluids. Cell-free DNA, which circulates freely in the blood, may or may not be tumor-derived, while circulating tumor DNA is specifically of tumor origin. Additionally, circulating tumor cells can be isolated from blood; these cells, shed from tumors into the bloodstream, typically survive only 1–2.5 h before immune clearance, though a small fraction can persist and metastasize to distant sites. Exosomes, small membrane-bound vesicles secreted by tumor cells, also carry molecular information about the tumor and have become a valuable source of biomarkers in liquid biopsy. Advances in detection technologies for these analytes have expanded the utility of liquid biopsy, facilitating the identification of somatic mutations and actionable genomic alterations in tumors. Finally, this review discusses the opportunities and challenges facing liquid biopsy and offers insights into its future development.

Prostate cancer (PCa) often manifests insidiously, with most patients being diagnosed at an advanced stage, leading to a poor prognosis. Early detection of PCa can significantly prolong overall survival by impeding the progression of metastasis. A commonly utilized screening method for detecting PCa is the prostate-specific antigen test. However, since the prostate-specific antigen lacks specificity and sensitivity for PCa identification, there is a paramount urgency to develop precise diagnostic biomarkers for early detection. Extracellular vesicles, known as exosomes, are released by cells into body fluids. Exosomes derived from cancer cells can carry genetic information about the tumor, including DNA, RNA, and proteins, which play crucial roles in tumor initiation, invasion, metastasis, and drug resistance. Studies have indicated that exosomes (including messenger RNAs, microRNAs, long noncoding RNAs and others) can enhance the sensitivity and specificity of PCa diagnosis, indicating their potential for early detection. This review highlights the biological characteristics and functions of exosomes, as well as recent advancements in their use for the diagnosis, prognosis, and treatment of prostate cancer.

Inflammatory bowel disease (IBD) is characterized by chronic inflammation of the gastrointestinal tract and primarily includes ulcerative colitis and Crohn’s disease. As the number of patients suffering from IBD increases, diagnosis and treatment have become pressing yet challenging tasks. A major challenge is that patients with IBD often do not exhibit characteristic symptoms, making it difficult to distinguish IBD from other intestinal abnormalities. Endoscopy is the most conventional method used to diagnose IBD; however, this technique is invasive and costly. Therefore, there is a need to develop affordable, non-invasive diagnostic methods, which underscores the importance of identifying biomarkers specific to IBD. It is now well established that the gut microbiome plays a significant role in the development of IBD, and changes in the abundance of various gut organisms have been widely studied to identify microbial signatures associated with the disease. This review discusses the current state of knowledge regarding biomarkers in IBD, with a primary focus on the gut microbiome, associated metabolic signatures, and their links with immunological biomarkers. These biomarkers will help propose an integrative model to better understand the pathophysiology of this complex disease. Such an integrated approach also offers insights into potential therapeutic targets for designing more effective treatment strategies for patients.

Escalating antimicrobial resistance is a global threat, emphasizing the need to explore alternative treatment options. Hence, we aimed to explore the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria.

This was an observational, cross-sectional study conducted at the Microbiology Department of Indus Hospital, Karachi, Pakistan, from January 2023 to October 2024. Carbapenem-resistant gram-negative rods isolated from clinical specimens received from the outpatient, emergency, and inpatient departments were included. Consecutive, non-probability sampling was employed for the collection of isolates. Identification of the organisms was confirmed using API® ID strips, and antimicrobial susceptibility for carbapenems and CAZ-AVI was determined via the Kirby-Bauer disc diffusion method.

A total of 158 bacterial isolates were characterized as carbapenem-resistant. Of these, 92 (58%) were Enterobacterales, and 66 (42%) were Pseudomonas aeruginosa. CAZ-AVI was susceptible in 17 (11%) of the isolates, of which four (24%) were Klebsiella spp. and Escherichia coli each, and nine (52%) were P. aeruginosa. CAZ-AVI-susceptible strains were predominant among patients aged 26–50 years (n = 6; 35%), most of whom were females (n = 10; 59%) and inpatients (n = 8; 47%). Clinical samples from patients with urinary tract infections grew the most CAZ-AVI-susceptible strains (n = 9; 53%).

Our study demonstrated low CAZ-AVI susceptibility in our carbapenem-resistant gram-negative bacterial strains. Understanding regional antimicrobial patterns in multidrug-resistant bacteria is crucial for the effective use of CAZ-AVI, along with the strict implementation of strategies for controlling antimicrobial resistance.

Epileptogenesis involves complex mechanisms, including inflammation and apoptosis. Rosiglitazone, a peroxisome proliferator-activated receptor gamma agonist, possesses anti-inflammatory and neuroprotective properties. This study investigated whether rosiglitazone can prevent pentylenetetrazole (PTZ)-induced kindling in mice by modulating inflammatory cytokines and apoptosis pathways.

Male C57BL/6 mice (n = 8 per group) were assigned to sham, control, or rosiglitazone-treated groups. Kindling was induced with intraperitoneal PTZ (40 mg/kg) every 48 h for 17 days. Rosiglitazone (0.1 mg/kg) was administered 30 m before each PTZ injection. Seizure progression was monitored, and hippocampal tissues were analyzed via immunohistochemistry and Western blotting to assess cytokine levels (interleukin (IL)-10, IL-17A, tumor necrosis factor-alpha, interferon-gamma), caspase-3 activity, and glial fibrillary acidic protein expression.

Rosiglitazone significantly delayed seizure progression, reduced seizure scores, and lowered pro-inflammatory cytokine levels (IL-17A, tumor necrosis factor-alpha, interferon-gamma) while increasing IL-10. Immunohistochemical analysis revealed fewer caspase-3-positive cells and reduced glial fibrillary acidic protein expression in the treatment group compared to controls.

Rosiglitazone exerts neuroprotective effects in PTZ-induced kindling, likely through its anti-inflammatory and anti-apoptotic actions. These findings underscore its potential as a therapeutic agent for mitigating epileptogenesis, warranting further investigation in combination therapies and clinical trials.

Despite significant advances in Parkinson’s disease (PD) treatment, it remains incurable, with limited therapeutic options. Currently, repurposing already tested, safe drugs has emerged as an effective therapeutic strategy against various neurodegenerative diseases, including PD. Using a drug-repurposing approach, the current study investigated the neuroregenerative potential of polysialic acid mimicking compounds, 5-nonyloxytryptamine oxalate (5-NOT) and Epirubicin (Epi), an anti-cancer drug, in 1-methyl-4-phenylpyridinium (MPP+)-treated human neuroblastoma SH-SY5Y cells as a PD model.

The excitotoxic model was established by exposing SH-SY5Y cells to 500 µM of MPP+ and subsequently treating them with the test compounds. The effect of MPP+-induced toxicity on cellular and nuclear morphology, as well as on the expression of neuroplasticity and cell survival proteins, were studied by immunostaining, gelatin zymogram, and Western blot assays.

Treatment with 5-NOT and Epi significantly promoted the survival of MPP+-challenged SH-SY5Y cells and prevented changes in their cellular and nuclear morphology by regulating the expression of microtubule-associated protein (MAP-2) and polysialylated-neural cell adhesion molecule (PSA-NCAM) and NCAM synaptic plasticity proteins. Further, 5-NOT and Epi treatment also protected SH-SY5Y cells by restoring levels of nitric oxide, matrix metalloproteinase, and stress response proteins. Interstingly, 5-NOT attenuated MPP+-induced toxicity in SH-SY5Y cells by regulating the intrinsic protein kinase AKT/BAD apoptotic pathway and the P-38 MAP kinase synaptic plasticity pathway.

These preliminary findings suggest that 5-NOT, as a potential polysialic acid glycomimetic, may serve as a promising drug candidate for targeting neurodegeneration of dopaminergic neurons, a hallmark feature of PD.

Oxidative stress could be a key process in acyclovir (ACV)-induced nephrotoxicity. N-acetylcysteine (NAC) is a water-soluble antioxidant with anti-inflammatory activity. This study aimed to evaluate the protective effect of NAC on ACV-induced nephrotoxicity in adult Wistar rats.

Forty adult male Wistar rats (200–220 g) were used. The rats were randomly divided into eight groups (n = 5/group) and were treated intraperitoneally daily for seven days as follows: Group 1 (Control) was administered water (0.2mL), while groups 2–4 were administered NAC (25, 50, and 100 mg/kg). Group 5 was administered ACV (150 mg/kg), while groups 6–8 were supplemented with NAC (25, 50, and 100 mg/kg) prior to treatment with ACV (150 mg/kg). On day 8, the rats were weighed and euthanized, and blood samples were collected for the assessment of biochemical markers. The kidneys were weighed and subjected to oxidative stress markers and histological evaluations.

ACV had no significant (p > 0.05) effects on the body and kidney weights of rats compared to the control. ACV produced significant (p < 0.001) elevations in kidney malondialdehyde, serum urea, creatinine, and uric acid levels in rats, which differed from the control. There were significant (p < 0.001) decreases in kidney glutathione, superoxide dismutase, peroxidase, and catalase, as well as serum chloride, potassium, bicarbonate, and sodium levels in ACV-treated rats compared to the control. ACV caused widening of Bowman’s space and tubular necrosis in the kidneys of rats. Nonetheless, NAC supplementation abrogated ACV-induced nephrotoxicity in a dose-dependent manner. Kidney histology was restored by NAC supplementation.

NAC protected against ACV-induced nephrotoxicity. This finding shows that NAC may have therapeutic potential for nephrotoxicity caused by ACV.

Pituitary tumors are common intracranial neoplasms that can cause significant morbidity due to hormonal dysregulation and compression of surrounding structures. Despite advancements in surgical techniques, challenges persist in treating large, invasive, or recurrent tumors, where complete resection is often difficult. The molecular and genetic mechanisms underlying pituitary tumorigenesis are not yet fully understood, limiting the development of targeted therapies. This review provides a comprehensive overview of recent advancements in neuroendoscopic treatment of pituitary tumors, with a focus on pathogenesis, technological innovations, clinical outcomes, and future directions. We highlight the potential of neuroendoscopic surgery to improve patient outcomes while addressing persistent challenges, such as the steep learning curve and limitations in instrument maneuverability. Future research should prioritize enhancing instrument design, developing 3D and augmented reality visualization systems, and improving training programs to further advance neuroendoscopic techniques.
