Excessive SOX8 reprograms energy and iron metabolism to prime hepatocellular carcinoma for ferroptosis.

Lipid peroxidation and redox imbalance are hallmarks of ferroptosis, an iron-dependent form of cell death. Growing evidence suggests that dysregulation in glycolipid metabolism and iron homeostasis substantially contribute to the development of hepatocellular carcinoma (HCC). However, there is still a lack of comprehensive understanding regarding the specific transcription factors that are capable of coordinating glycolipid and redox homeostasis to initiate the onset of ferroptosis.

Tumor specificity of WNT ligands and receptors reveals universal squamous cell carcinoma oncogenes.

Background: The WNT signal pathway has myriad family members, which are broadly involved in embryonic development and human cancer. Over-activation of WNT-β-Catenin signaling promotes cancer cell proliferation and survival. However, how diverse components of WNT signaling specifically engaged in distinct tumor types remains incompletely understood.

Purification and characterization of glucoamylase of Aspergillus oryzae from Luzhou-flavour Daqu.

Objective: To obtain novel glucoamylase from Daqu microbe.

Results: A dominant strain known as LZ2 with high activity of hydrolyzing starch was isolated from Luzhou Daqu, a Chinese traditional fermentation starter. The LZ2 was identified as Aspergillus oryzae by 18S rDNA sequence analysis.
