Liver fibrosis, characterized by the overproduction of extracellular matrix proteins within liver tissue, poses a rising global health concern. However, no approved antifibrotic drugs are currently available, highlighting the critical need for understanding the molecular mechanisms of liver fibrosis. This knowledge could not only aid in developing...

Nonalcoholic fatty liver disease (NAFLD) is a prevalent hepatic disease in the world. Disorders of branched chain amino acid (BCAA) metabolism is involved in various diseases. In this study, we aim to explore the role of BCAA metabolism in the development of NAFLD and the protective effect of BCATc Inhibitor 2, an inhibitor of cytosolic branched ch...

Acute liver failure (ALF) is an unfavorable condition characterized by the rapid loss of liver function and high mortality. Chrysophanol-8-O-glucoside (CPOG) is an anthraquinone derivative isolated from rhubarb. This study aims to evaluate the protective effect of CPOG on lipopolysaccharide (LPS)/D-GalN-induced ALF and its underlying mechanisms. LP...

Inhibiting cancer metabolism via glutaminase (GAC) is a promising strategy to disrupt tumor progression. However, mechanism regarding GAC acetylation remains mostly unknown. In this study, we demonstrate that lysine acetylation is a vital post-translational modification that inhibits GAC activity in non-small cell lung cancer (NSCLC). We identify t...

Altered glutamine metabolism is an important aspect of cancer metabolic reprogramming. The GLS isoform GAC (glutaminase C), the rate-limiting enzyme in glutaminolysis, plays a vital role in cancer initiation and progression. Our previous studies demonstrated that phosphorylation of GAC was essential for its high enzymatic activity. However, the mol...

The gene trim7 encodes at least four isoforms Glycogenin-interacting protein 1 (GNIP1), GNIP2, GNIP3 and Tripartite motif containing 7 (TRIM7). GNIP1, the longest isoform, has been reported acting as an oncogene. However, it is very interesting that TRIM7, the shortest isoform, only 15 amino acids different from GNIP1 in C-terminal, acts in a compl...

... These morphological changes are not merely a consequence of liver injury but actively contribute to the progression of ALD. Mitochondria are also involved in the regulation of apoptosis, and alcohol-induced mitochondrial dysfunction can trigger apoptotic pathways in hepatocytes [23,24]. This process is mediated through the release of pro-apoptotic factors like cytochrome c, further contributing to liver injury. ...
... According to the fndings, the binding of chrysophanol-8-0-glucoside (pulmatin) to the MAPK3 catalytic domain Chrysophanol, an anthraquinone metabolite obtained from the Rheum genus, has been found to possess anticancer properties in recent studies [51][52][53]. In addition, it exhibits anti-infammatory activity [54] and provides neuroprotection efects [55]. ...
... Tripartite motif containing 15 (TRIM15) enhances degradation of KEAP1 via K48-linked ubiquitination, which is the principal regulator of NRF2 degradation, causing NRF2 to escape from KEAP1-mediated degradation, and thus promoting antioxidant response, cell proliferation and invasion in NSCLC [77]. Tripartite motif containing 21 (TRIM21) can interact with GAC, leading to K63-linked ubiquitination and downregulation of protein activity, thus inhibiting proliferation and tumorigenesis in NSCLC cells [78]. Also, TRIM21 polyubiquitinates and induces proteasomal degradation of phosphofructokinase platelet (PFKP), which can be inhibited by AKT-mediated phosphorylation and F-action bundling and stress-fibre formation spatial sequestration, causing the downregulation of glycolysis in NSCLC cells [64]. ...
... Our results show that the catabolism of ketone bodies is also increased which indicates a futile circle establishment. The upregulation of the OXCT1 enzyme has been described as involved in inflammation through nuclear factor kappa B (NF-κB) activation, however, the exact signaling mechanism is not clearly known [36]. The compound downregulated OXCT1 in 5.5-fold. ...
... Toton et al. [65] recently observed PKC's influence on the autophagy of glioblastoma cells and found that a loss of PKC led to a downregulation in the expression of autophagic signals, thus presenting a potential therapeutic effect for glioblastoma. Additional studies elucidated that the Fas apoptotic inhibitory molecule regulates macroautophagy through the modulation of the mTOR pathway and PKCmediated phosphorylation in lung adenocarcinoma [66]. In hypoxic conditions, PKC interacts with protein tyrosine phosphatases-PTPN12 and triggers endothelial autophagy via AMPK activation to foster angiogenesis [67]. ...
... As the longest isoform, GNIP1 promotes the degradation of 14-3-3ζ (also called tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (YWHAZ) through K48-linked ubiquitination. Based on that, GNIP1 can promote autophagy, proliferation and migration in NSCLC cells [69,70]. Tripartite motif containing 11 (TRIM11) ubiquitinates dual-specificity phosphatase 6 (DUSP6), subsequently promotes proliferation, and inhibits apoptosis in NSCLC cells by regulating DUSP6-ERK1/2 pathway [71]. ...
