The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Genetic variability in exon 9 of PEPCK-M gene in different strains of chickens using PCR-RFLP method [PDF]
Phosphoenolpyruvate carboxykinase (PEPCK) catalyzes the first step of the gluconeogenesis cycle. There are two isozymes forms of this enzyme, cytosolic phosphoenolpyruvate carboxykinase (PEPCK-C) and mitochondrial phosphoenolpyruvate carboxykinase (PEPCK-

O-GlcNAcylated p53 in the liver modulates hepatic glucose production
p53 regulates signalling pathways involved in metabolic homeostasis. Here the authors show that O-GlcNAcylation of p53 in the liver plays a key role in the physiological regulation of glucose homeostasis, potentially via controlling the expression of the

Glucocorticoid exposure in late gestation permanently programs rat hepatic phosphoenolpyruvate carboxykinase and glucocorticoid receptor expression and causes glucose intolerance in adult offspring [PDF]
Low birth weight in humans is predictive of insulin resistance and diabetes in adult life. The molecular mechanisms underlying this link are unknown but fetal exposure to excess glucocorticoids has been implicated, The fetus is normally protected from ...
