Resveratrol (3,5,4-trihydroxystilbene, RES), a natural antioxidant, prevents bone loss by attenuating damage caused by oxidative stress. Our previous research revealed that the forkhead box O1 (FoxO1)/β-catenin signaling pathway affected the proliferation and differentiation of osteoblasts through its regulation of redox balance, and RES regulated the expression of FoxO1 to control white adipos...

Type 2 diabetes seriously affects human health and burdens public health systems. Pancreatic β‑cell apoptosis contributes to a reduction in β‑cell mass, which is responsible for the occurrence of type 2 diabetes. However, the mechanism that underlies this effect remains unclear. In the present study, the role of forkhead box O1 (Foxo1) was investigated (which is a key regulatory factor in β‑cel...

It has previously been demonstrated that curcumin possesses an antitumor activity, which is associated with its ability to induce G2/M cell cycle arrest and apoptosis. However the detailed underlying mechanisms remain unclear. The present study aimed to investigate the efficacy and underlying mechanism of curcumin‑induced cell cycle arrest and apoptosis in U87 human glioblastoma cells. By immun...

Forkhead box O-class 1 (FOXO1) is a key regulator of glucose homeostasis, cell-cycle progression, and apoptosis. Its functions are modulated by forkhead box G1 (FOXG1), which acts as a transcriptional repressor with oncogenic potential. Real-time PCR and immunohistochemical staining were performed in 174 primary bladder cancer specimens and 21 normal bladder mucosae to evaluate these genes. FOX...

Sodium meta-arsenite (SA) is implicated in the regulation of hepatic gluconeogenesis-related genes in vitro; however, the effects in vivo have not been studied. We investigated whether SA has antidiabetic effects in a type 2 diabetic mouse model. Diabetic db/db mice were orally intubated with SA (10 mg kg(-1) body weight/day) for 8 weeks. We examined hemoglobin A1c (HbA1c), blood glucose levels...

BACKGROUND Aging is a major risk factor for the development of atherosclerosis and coronary artery disease. Through a microarray approach, we have identified a microRNA (miR-217) that is progressively expressed in endothelial cells with aging. miR-217 regulates the expression of silent information regulator 1 (SirT1), a major regulator of longevity and metabolic disorders that is progressively ...

Wound healing impairment is a well-documented phenomenon in clinical and experimental diabetes, and in diabetic wound healing impaired fibroblast has been linked to increased levels of tumor necrosis factor-α (TNF-α). A number of signaling pathways including TNF-α/forkhead box O1 (FOXO1) and transforming growth factor-β1 (TGF-β1)/Smads in fibroblasts appear to play a cardinal role in diabetic w...

RATIONALE Forkhead box-O transcription factors (FoxOs) transduce a wide range of extracellular signals, resulting in changes in cell survival, cell cycle progression, and several cell type-specific responses. FoxO1 is expressed in many cell types, including endothelial cells (ECs). Previous studies have shown that Foxo1 knockout in mice results in embryonic lethality at E11 because of impaired ...
