Based on the cellular and molecular mechanisms underlying hepatic fibrogenesis, several kinds of approaches have been proposed to treat liver fibrosis. Among a number of growth factors and cytokines that regulate collagen metabolism, transforming growth factor (TGF)-β is the most potent factor to accelerate liver fibrosis by activating hepatic stellate cells, stimulating collagen gene transcription, and suppressing matrix metalloproteinases expression. Thus, TGF-β as well as its intracellular mediators, Smad proteins, can be potential therapeutic targets for liver fibrosis. Constitutive phosphorylation and nuclear accumulation of Smad3 is the common feature of activated stellate cells. We have synthesized a novel small compound that inhibits Smad3-dependent collagen gene transcription by promoting nuclear import of a transcriptional repressor, YB-1. Another insight into anti-fibrotic strategies is the contribution of bone marrow-derived cells to the regression of liver fibrosis. Administration of granulocyte-colony stimulating factor enhanced the migration of bone marrow-derived cells into fibrotic liver tissue and accelerated the regression of experimental liver fibrosis. We have recently identified novel unknown factors expressed by bone marrow-derived cells that not only ameliorate liver fibrosis but also accelerate regeneration of fibrotic liver.

Introduction: The risk of HCC is twice as high in diabetic patients compared to non-diabetic ones, suggesting that diabetes advances carcinogenesis in the liver through a variety of mechanisms. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have been shown to improve liver outcomes, emerging as promising agents to treat hepatocellular carcinoma (HCC) in patients with type 2 diabetes mellitus (T2DM).
Methods: We searched PubMed and Scopus databases for articles presenting an association between SGLT2is and HCC to explore the putative mechanisms of action underlying the anti-proliferative activity of SGLT2is.

We report the case of a 70-year-old woman with advanced hepatic encephalopathy (HE) secondary to metabolic dysfunction-associated steatohepatitis (MASH)-related cirrhosis who exhibited an excellent response to portosystemic shunt embolization. Four years earlier, she was diagnosed as having MASH-related cirrhosis accompanied by multiple mesenteric vein-inferior vena cava shunts. As her condition progressed, she suffered recurrent HE that was unresponsive to oral medication, prompting the decision to proceed with shunt embolization.

Introduction: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic interstitial pneumonia, which is characterised by progressive worsening of dyspnoea and lung function. Nintedanib treatment is recommended to slow IPF disease progression. The aim of this post-marketing surveillance (PMS) study was to evaluate the safety and effectiveness of nintedanib over 24 months in patients with IPF in a real-world setting in Japan.

Background: Bile salts enriched nanovesicles (bilosomes) have been attention worthy in the past few years due to their distinctive effect on the enhancement of drug delivery through various physiological administration routes. Oral delivery of multifunctioning phytochemical curcumin has faced a lot of difficulties due to its scarce solubility and poor oral bioavailability.
Objective: The current investigation aimed to develop curcumin loaded bilosomes for improvement of oral curcumin bioavailability with maximum efficiency and safety.

Background And Aim: Identifying the factors contributing to the progression of metabolic dysfunction-associated steatotic liver disease (MASLD), a lifestyle-related disease, is crucial for preventing future liver-related deaths. This study aimed to epidemiologically investigate factors, including single-nucleotide polymorphisms (SNPs) associated with alanine aminotransferase (ALT) levels >30 U/L and potential risk factors for liver fibrosis, in a general population cohort of patients with MASLD.
Methods: Among 1059 participants in the health checkup project, 228 who were diagnosed with MASLD were analyzed.
