1-phenyl-3-methyl-5-pyrazolone activates the AMPK pathway to alleviate western-diet induced metabolic dysfunction-associated steatohepatitis in mice.

Background & Aims: Approved drugs for the treatment of metabolic dysfunction-associated steatohepatitis (MASH) are limited, although it has become the most common chronic liver disease worldwide. 1-phenyl-3-methyl-5-pyrazolone (PMP) possesses various biological effects such as anti-inflammatory and antioxidant. However, the effects and underlying mechanism of PMP in MASH remain unclear.

The PKHD1 gene inhibits tumor proliferation and invasion in intrahepatic cholangiocarcinoma by activating the Notch pathway.

Intrahepatic cholangiocarcinoma (ICC), one type of highly malignant tumor, has a poor prognosis. However, the specific role of the polycystic kidney and hepatic disease 1 (PKHD1) gene in ICC has not yet been evaluated. This study aimed to investigate the potential function and mechanism of the PKHD1 gene in ICC.

Varied immune responses of HBV-specific B cells in patients undergoing pegylated interferon-alpha treatment for chronic hepatitis B.

Background & Aims: The changes in HBV-specific B cells in patients with chronic hepatitis B (CHB) undergoing pegylated interferon-α (PEG-IFNα) treatment and achieving functional cure remain unclear. We aimed to evaluate the alterations in HBV-specific B cells during treatment and therefore explored the mechanism of functional recovery of HBsAg-specific B cells.

Methods: We included 39 nucleos(t)ide analogue-treated patients with CHB who received sequential combination therapy with PEG-IFNα and eight treatment-naïve patients.
