De novo pyrimidine synthesis fuels glycolysis and confers chemoresistance in gastric cancer.

Metabolic reprogramming is a hallmark in multiple types of malignancies. Fast-growing cancer cells require facilitated synthesis of essential metabolites and excessive energy production. However, whether they are internally coordinated remains largely unknown.

pVHL promotes lysosomal degradation of YAP in lung adenocarcinoma.

Yes-associated protein (YAP) is a vital transcriptional co-activator that activates cell proliferation and evasion of apoptosis for the promotion of tumorigenesis. The von Hippel-Lindau tumor suppressor protein (pVHL), as a critical component of E3 ubiquitin ligase, targets various substrates to regulate tumor progression. However, the precise molecular mechanisms of pVHL during tumorigenesis remain largely unclear.

Up-regulation of FUT8 inhibits TGF-β1-induced activation of hepatic stellate cells during liver fibrogenesis.

Liver fibrosis is a continuous wound healing response caused by chronic liver injury, and the activation of hepatic stellate cells (HSCs) is considered as the main event for it. Core fucosylation catalyzed by FUT8 refers to adding the fucosyl moiety to the innermost GlcNAc residue of N-linked oligosaccharides and is involved in many biological processes such as cell differentiation, migration, and signaling transduction. Aberrant core fucosylation is associated with a variety of diseases including cardiovascular disease, tumors and neuroinflammation, but much less is understood in liver fibrosis.

RACK1 promotes the invasive activities and lymph node metastasis of cervical cancer via galectin-1.

Cervical cancer remains the first leading cause of cancer-related mortality among female reproductive system malignancies worldwide, and invasion and lymph node metastasis of cervical cancer represent the major reason for its poor prognosis. In this study, we found that RACK1 facilitated tumor cell invasion and lymphatic tube formation in vitro, as well as promoted lymphangiogenesis and lymph node metastasis in vivo in a galectin-1-dependent manner. Mechanism studies revealed that RACK1 promoted the expression and secretion of galectin-1 by reducing miR-1275 levels.
