Accumulating evidence reveals the association of 1, 3-dichloro-2-propanol (1, 3-DCP) exposure and lipogenesis. Alliin, the most abundant sulphur compound in garlic, has been demonstrated to exhibit hypoglycemic, antioxidant and anti-inflammatory activities. Here, we showed that alliin attenuated lipogenesis induced by 1,3-DCP and that the reduction was due to activation of the AMPK pathway. HepG2 cells exposed to 1,3-DCP exhibited significant increase of triglyceride(TG) and total cholesterol(TC), and alliin reduced the accumulation. Most importantly, alliin could up-regulate the phosphorylation of AMPK and down-regulate protein and gene expressions of SREBP-1; FAS; SREBP-2;HMGCR in 1,3-DCP-induced HepG2 cells. The results demonstrated that alliin was effective on attenuating 1,3-DCP-induced lipogenesis via activation of the AMPK-SREBPs signaling pathway in HepG2 cells.

Novel thiazole analogs 3a, 3b, 4, 5, 6a-g, 8a, 8b, 9a-c, 10a-d and 11 were designed and synthesized as molecular mimetics of sunitinib. antitumor activity of the obtained compounds was investigated against HepG2, HCT-116, MCF-7, HeP-2 and HeLa cancer cell lines. The obtained data showed that compounds 3b and 10c are the most potent members toward HepG2, HCT-116, MCF-7 and HeLa cells.

Background: Hepatocellular carcinoma (HCC) is a significant global health concern, with chronic hepatitis B virus (HBV) infection being a major contributor. Understanding the mechanisms of HBV-associated HCC is crucial to improving the prognosis and developing effective treatments.
Methods: HBV-associated HCC datasets (GSE19665, GSE121248, GSE55092, GSE94660, and TCGA-LIHC) acquired from public databases were mined to identify key driver genes by differentially expressed gene analysis, weighted gene co-expression network analysis (WGCNA), followed by protein-protein interaction network analysis, Lasso-Cox regression analysis, and randomforestSRC algorithm.
Sulfone-Embedded NIR Fluorophore with Large Stokes Shift for Monitoring Viscosity Changes during NAFLD-Induced Ferroptosis.

The accumulation of lipids in hepatocytes in nonalcoholic fatty liver disease (NAFLD) leads to an increase in reactive oxygen species and changes in the intracellular microenvironment, while ferroptosis is the result of the accumulation of iron-dependent lipid peroxidation. Studies have shown that ferroptosis plays an important role in the pathogenesis of NAFLD. Herein, we have developed a viscosity-sensitive fluorescence probe PTSO with near-infrared emission and a large Stokes shift, which were achieved by introducing the sulfone group into the dioxothiochromen-malononitrile fluorophore as an electron-withdrawing group.

Calcium hydroxide nanoparticles (Ca(OH)NPs) possess potent antimicrobial activities and unique physical and chemical properties, making them valuable across various fields. However, limited information exists regarding their effects on genomic DNA integrity and their potential to induce apoptosis in normal and cancerous human cell lines. This study thus aimed to evaluate the impact of Ca(OH)NPs on cell viability, genomic DNA integrity, and oxidative stress induction in human normal skin fibroblasts (HSF) and cancerous hepatic (HepG2) cells.

Platinum(II)-based antitumor drugs are widely used in clinics but limited by severe side effects and resistance. Multi-target Platinum(IV) complexes are emerging as ideal alternatives. Heme oxygenase-1 (HO-1) works as a rate-limiting step in heme degradation and is overexpressed in malignant tumors.
