Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly prevalent worldwide and is frequently encountered in patients undergoing liver transplantation and hepatic surgery. Although hepatic steatosis was once considered a relatively benign condition, accumulating evidence indicates that MASLD is associated with reduced tolerance to ischemic stress and increased susceptibility to ischemia–reperfusion injury, which may contribute to graft dysfunction and postoperative liver injury. In this mini review, we used the concept of hepatic resilience, referring to the ability of the liver to maintain homeostasis during stress and recover after injury. We discussed how MASLD may reduce hepatic resilience through mechanisms involving lipotoxicity, mitochondrial dysfunction, oxidative stress, inflammatory activation, regulated cell death, and impaired regeneration. MASLD represents a heterogeneous disease spectrum, and susceptibility to ischemia–reperfusion injury may differ according to disease stage and phenotype, particularly in the presence of progressive inflammation and fibrosis. We further summarized strategies aimed at improving hepatic resilience, including metabolic optimization, mitochondrial protection, modulation of reperfusion-associated inflammation, and enhancement of tissue repair. However, current evidence remains limited by the paucity of human studies and validated approaches for assessing hepatic resilience. Further investigation of these mechanisms may help develop individualized strategies to protect the liver in patients with MASLD during hepatic surgery and transplantation.

Fuzheng Huayu, a patent herbal product, has shown promise in liver fibrosis and cirrhosis. The effect of Fuzheng Huayu on portal hypertension due to cirrhosis and the consequent complications needs further investigation. In this study, we aimed to evaluate the association of adjunctive Fuzheng Huayu plus entecavir with liver-related events and variceal regression in patients with compensated HBV-related cirrhosis.

A post hoc analysis was conducted using data from two randomized controlled trials implemented at eight clinical centers in China (ClinicalTrials.gov numbers: NCT02945982; NCT02945956). Patients with compensated hepatitis B virus-related cirrhosis were enrolled from October 2017 to March 2021. The primary endpoint was a composite of liver events and the individual components, including variceal bleeding, ascites, overt hepatic encephalopathy, and hepatocellular carcinoma.

A total of 218 participants (Fuzheng Huayu group: 110 and control group: 108; mean age, 51.5 years; 66.5% male; median observational follow-up time, 23.1 months) were included in the primary analysis. The occurrence of total liver events was less frequent in the Fuzheng Huayu group than in the control group (hazard ratio = 0.408 [0.187–0.892], P = 0.020). Among the individual components of liver events, the incidence of ascites was significantly lower in the Fuzheng Huayu group than in the control group (1.8% vs. 9.3%, P = 0.016). In addition, the rate of variceal regression was significantly higher in the Fuzheng Huayu group (27.3% vs. 10.2%, P < 0.001). Finally, there were no significant differences in the occurrence of adverse events between the two groups.

In this post hoc analysis of two randomized controlled trials, adjunctive Fuzheng Huayu plus entecavir was associated with fewer liver-related events, particularly ascites, and a higher rate of variceal regression than entecavir alone in patients with compensated hepatitis B virus-related cirrhosis. These findings warrant confirmation in adequately powered prospective studies.

Since their first inception, neuroendocrine neoplasms of the breast have undergone many iterations of classification and definition. Taken together with their extremely low incidence, the ever-evolving landscape has made diagnosis, treatment, and research exceedingly challenging.

Our patient is a 45-year-old female who had a breast mass with clinical workup favoring a breast primary. A diagnosis of small cell carcinoma was established after an extensive clinical and pathologic workup. The mass did not respond to traditional neoadjuvant platinum-based chemotherapy, and she underwent a total mastectomy. Shortly thereafter, imaging revealed widely metastatic disease involving the brain, chest, abdomen, and pelvis. She received whole-brain radiation and, given the previous lack of response to chemotherapy, was recommended to try off-label tarlatamab. To date, with a short-term follow-up of 5 months, after whole-brain radiotherapy administered concurrently with the first cycle of tarlatamab, subsequent imaging showed near-complete radiographic resolution of extracranial metastatic disease, while the brain lesions also showed radiographic resolution on follow-up MRI.

We report the novel and preliminary use of tarlatamab in a patient with small cell neuroendocrine carcinoma of the breast, with short-term follow-up. We also discuss the most critical challenges associated with this rare pathologic diagnosis and the important elements to consider to ensure that metastatic disease is excluded.

The huge burden of type 1 diabetes mellitus (T1DM) has been a source of concern globally since the Industrial Revolution in the 18th–19th centuries. To this end, studies have shown that certain environmental changes that accompanied the Revolution may have increased the risk and burden of the disease in genetically predisposed individuals. However, documented studies that synthesize these environmental triggers are scarce. As a result, the current study was conceived to synthesize the environmental triggers of T1DM to boost public awareness. Relevant information was retrieved from reputable academic databases; namely, Scopus, PubMed, SpringerLink, and Embase. The results showed that chemical exposure, viral infection, gut microbiome disruption, vitamin and mineral deficiencies, inadequate or exclusive breastfeeding, as well as early exposure to infant feeding formulas could increase the risk and burden of T1DM in genetically predisposed individuals. As a consequence, these triggers could compromise the expression of certain genes involved in insulin synthesis and immune function, such as the human leukocyte antigen (HLA), insulin (INS), cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), and protein tyrosine phosphatase non-receptor type 22 (PTPN22) genes. This would result in a dysfunctional immune system in which immune cells, such as T-cells and B-cells and molecules, such as cytokines would attack self-tissues, thus causing autoimmunity of the pancreatic beta cells. Environmental triggers could also induce the T1DM pathophysiology by modifying the epigenome of the mentioned genes. Furthermore, some epigenetic changes could be reversed, which would infer that treatment procedures that would include the pathophysiology of the environmental triggers could be more effective.

Emerging evidence suggests that RNA-binding motif (RBM) proteins are involved in hepatocarcinogenesis and act either as oncogenes or tumor suppressors. The objective of this study was to investigate the role of RBM34, an RBM protein, in hepatocellular carcinoma (HCC).

We first examined the expression of RBM34 across cancers. The correlation of RBM34 with clinicopathological features and the prognostic value of RBM34 for HCC was then investigated. Functional enrichment analysis of RBM34-related differentially expressed genes (DEGs) was performed to explore its biological function. RNA sequencing (RNA-seq) was applied to identify downstream genes and pathways affected upon RBM34 knockout. The correlation of RBM34 with immune characteristics was also analyzed. The oncogenic function of RBM34 was examined in in vitro and in vivo experiments.

RBM34 was highly expressed in hepatocellular carcinoma and correlated with poor clinicopathological features and prognosis. RBM34 was positively associated with tumor immune cell infiltration, biomarkers of immune cells, and immune checkpoint expression. A positive correlation was also observed between RBM34, T cell exhaustion, and regulatory T cell marker genes. Knockout of RBM34 significantly inhibited cell proliferation, migration, and xenograft tumor growth, and sensitized HCC cells to sorafenib treatment. RBM34 inhibition reduced FGFR2 expression and affected PI3K-AKT pathway activation in HCC cells.

Our study suggests that RBM34 may serve as a new prognostic marker and therapeutic target of HCC.

Naringenin is an anti-inflammatory flavonoid that has been studied in chronic liver disease. The mechanism specific to its antifibrosis activity needs further investigation This study was to focused on the cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) pathway in hepatic stellate cells and clarified the antifibrosis mechanism of naringenin.

The relationship between the cGAS-stimulator of interferon genes (STING) pathway and liver fibrosis was analyzed using the Gene Expression Omnibus database. Histopathology, immunohistochemistry, fluorescence staining, Western blotting and polymerase chain reaction were performed to assess gene and protein expression levels associated with the cGAS pathway in clinical liver tissue samples and mouse livers. Molecular docking was performed to evaluate the relationship between naringenin and cGAS, and western blotting was performed to study the expression of inflammatory factors downstream of cGAS in vitro.

Clinical database analyses showed that the cGAS-STING pathway is involved in the occurrence of chronic liver disease. Naringenin ameliorated liver injury and liver fibrosis, decreased collagen deposition and cGAS expression, and inhibited inflammation in carbon tetrachloride (CCl4)-treated mice. Molecular docking found that cGAS may be a direct target of naringenin. Consistent with the in vivo results, we verified the inhibitory effect of naringenin on activated hepatic stellate cells (HSCs). By using the cGAS-specific agonist double-stranded (ds)DNA, we showed that naringenin attenuated the activation of cGAS and its inflammatory factors affected by dsDNA. We verified that naringenin inhibited the cGAS-STING pathway, thereby reducing the secretion of inflammatory factors by HSCs to ameliorate liver fibrosis.

Interrupting the cGAS-STING pathway helped reverse the fibrosis process. Naringenin has potential as an antihepatic fibrosis drug.
