Objective: To investigate the effect of Pteris semipinnata L. (PsL) extract Ent-11alpha-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F)-on HepG2 cells and explore its potential mechanism.
Methods: Cytotoxicity of 5F was studied in HepG2 cells treated with different doses of 5F (0 - 80 mg/L) for 24 h and cell viability was determined by MTT assay. To analyze apoptosis qualitatively, the Hoechst/PI assay was used. The level of Bax in mitochondria fraction of 5F-treated HepG2 cells was determined by western blotting. The levels of cyto-c and AIF in the cytosol were analyzed by western blotting.
Results: The cytotoxicity of 5F on HepG2 cells was elevated with the increasing of 5F concentrations, as evidenced by the cell viability assay. The apoptotic cells characterized by condensed neclei were observed after the exposure of HepG2 cells to 5F. The level of Bax in mitochondria fraction of 5F-treated HepG2 cells increased. The levels of cyto-c and AIF in the cytosol of 5F-treated HepG2 cells increased.
Conclusion: 5F mediated apoptosis involves mitochondria-dependent pathway and 5F might have a therapeutic value against human cancer cell lines and especially on hepatocellular carcinoma (HCC) cells.

Cold‑inducible RNA‑binding protein (CIRP) is a cold shock protein implicated in the regulation of multiple biological processes depending on its cellular localization. However, to the best of our knowledge, the role of CIRP in liver regeneration and injury after hepatectomy has not been investigated. The present study was therefore designed to explore whether CIRP is involved in liver regeneration after hepatectomy and its specific role and underlying molecular mechanism.

Many cancers have displayed resistance to chemotherapeutic drugs over the past few decades. EGFR has emerged as a leading target for cancer therapy inhibiting tumor angiogenesis. Besides, studies strongly suggest that blocking telomerase activity could be an effective way to control the growth of certain cancer cells.

Selenium (Se) intake or selenoprotein overexpression can cause abnormal glucose metabolism and increase the risk of type 2 diabetes (T2D). The purpose of this study is to observe whether glycolysis bypass in the de novo serine synthesis pathway (SSP) is activated under high-Se stress in vitro. Initially, HCT-116, L02, HepG2, and differentiated C2C12 cells were exposed to five selenomethionine (SeMet) concentrations (0.

Alkaline phosphatase (ALP) is a critical biomarker associated with various physiological and pathological processes, making its detection essential for disease diagnosis and biomedical research. In this study, we developed a novel, simple, and portable visual quantification method for ALP activity in cells using an efficient CuZnS nanomaterial with peroxidase-like properties, integrated into a smartphone-based platform for enhanced usability. The CuZnS nanomaterial catalyzes the breakdown of H₂O₂, generating ·OH radicals that oxidize the colorless substrate TMB into blue oxTMB, which is subsequently reduced back to TMB by ascorbic acid (AA).
