2.3.1.B41 down decline of SIRT6 expression when bladder cancer progresses from stage T2 to stage T4 729849 2.3.1.B41 down enzyme expression is significantly reduced in human ovarian cancer tissues compared to the normal tissues 738169 2.3.1.B41 down H2O2 treatment significantly reduces Sirt6 protein. Stress-induced downregulation of Sirt6 is likely involved in the pathogenesis of diabetic retinopathy 729362 2.3.1.B41 down high-glucose causes Sirt6 and p-AMPK downregulation in podocytes. High-glucose conditions decrease Sirt6 expression levels significantly 756973 2.3.1.B41 down high-glucose conditions decrease Sirt6 expression levels significantly -, 756973 2.3.1.B41 down in cortical and hippocampal neurons SIRT6 is downregulated during maturation in vitro, reaching the lowest expression at 11 days in vitro 730473 2.3.1.B41 down in Hep-G2 cells, doxorubicin treatment results in significant increases in SIRT1 and SIRT4 mRNA expression and downregulation of SIRT6 mRNA level by 36 h 757883 2.3.1.B41 down minute cholesterol crystals significantly suppress SIRT6 expression in endothelial cells 756672 2.3.1.B41 down several factors regulate the expression of the SIRT6 gene. PARP1 may inhibit the expression of SIRT6, and the presence of PJ-34, a PARP1 inhibitor, results in enhanced mRNA level of nuclear SIRT6. A role for the transcription factor E2F1 as an enhancer of glycolysis and inhibitor of the expression of SIRT6. E2F1 directly binds the SIRT6 promoter and suppresses SIRT6 promoter activity under both normoxic and hypoxic culture conditions. In embryos and neural stem cells, SIRT6 expression becomes suppressed by maternal diabetes in vivo or high glucose in vitro through oxidative stress 757931 2.3.1.B41 down several factors regulate the expression of the SIRT6 gene.
