Sodium taurocholate co-transporting polypeptide deficiency attenuates acetaminophen-induced hepatotoxicity via regulating expression of drug metabolism enzymes in mice.

Acetaminophen (APAP) overdose can induce liver injury and is generally accompanied by disruption of bile acid homeostasis. Physiologically, sodium taurocholate co-transporting polypeptide (NTCP) participates in the uptake of bile acids from portal blood into hepatocytes to maintain enterohepatic recirculation but its role in APAP-induced hepatotoxicity is unclear. Wild-type (WT) C57BL/6J and NTCP knockout (KO) mice were injected with 400mg/kg APAP and liver injury was evaluated by serum biochemical markers and histologic evaluation.

Unraveling the potential mechanism and prognostic value of pentose phosphate pathway in hepatocellular carcinoma: a comprehensive analysis integrating bulk transcriptomics and single-cell sequencing data.

Hepatocellular carcinoma (HCC) remains a malignant and life-threatening tumor with an extremely poor prognosis, posing a significant global health challenge. Despite the continuous emergence of novel therapeutic agents, patients exhibit substantial heterogeneity in their responses to anti-tumor drugs and overall prognosis. The pentose phosphate pathway (PPP) is highly activated in various tumor cells and plays a pivotal role in tumor metabolic reprogramming.

A class-incremental learning approach for learning feature-compatible embeddings.

Humans have the ability to constantly learn new knowledge. However, for artificial intelligence, trying to continuously learn new knowledge usually results in catastrophic forgetting, the existing regularization-based and dynamic structure-based approaches have shown great potential for alleviating. Nevertheless, these approaches have certain limitations.

The occurrence of immune-related adverse events is an independent risk factor both for serum HBsAg increase and HBV reactivation in HBsAg-positive cancer patients receiving PD-1 inhibitor combinational therapy.

Background: Previous studies have suggested the potential of PD-1/PD-L1 inhibitors in the treatment of chronic HBV infection. However, since phase III clinical trials have not yet been announced, additional clinical insights may be obtained by observing changes in serum hepatitis B surface antigen (HBsAg) and HBV-DNA levels in cancer patients undergoing PD-1 inhibitor therapy.

Objective: To explore the effects of PD-1 inhibitor combinational therapy on serum HBsAg and HBV-DNA levels, investigate the incidence of HBsAg loss, HBV reactivation (HBVr), and immune-related adverse events (irAEs), and identify the risk factors associated with significant HBsAg fluctuations and HBVr.

[Progress in functions and mechanisms of immunosuppressive neutrophil subsets: An update].

Neutrophils are the most abundant circulating leukocytes in healthy adults, serving as the first-line defense against infections. In the last few years, scientists have reported neutrophils of immune suppressive properties, such as tumor-associated neutrophils (TAN) and low-density neutrophils (LDN). These neutrophils are found to be involved in many physiological and pathological conditions owing to their ability of regulating T cell functions and promoting angiogenesis and tumor growth through a number of mechanisms, including PD-1/PD-L1, antigen presentation, reactive oxygen species (ROS), arginase-1 (Arg1), inducible nitric oxide synthase (iNOS), etc.
