Transforming growth factor-β (TGF-β) is a ubiquitous cytokine playing an essential role in cell proliferation, differentiation, apoptosis, adhesion and invasion, as well as in cellular microenvironment. In malignant diseases, TGF-β signaling features a growth inhibitory effect at an early stage but aggressive oncogenic activity at the advanced malignant(More)
Aldo-keto reductase 1 member B1 (AKR1B1) is pathogenically involved in diabetic complications by driving glucose flux through polyol pathway; a variety of AKR1B1 inhibitors has been developed for the treatment of diabetic complications and a body of invaluable preclinical and clinical data have been collected through decades' efforts. Recent studies have(More)
OBJECTIVE To investigate the effect of pioglitazone on the expression of Toll-like receptor 4 (TLR4) in renal tissue of diabetic rats. METHODS The male Sprague Dawlry rats (n=57) were randomly divided into the control group (n=9) and experimental group (n=48). The experimental rats were injected introperatoneally with 50 mg/kg streptozotocin (STZ) and the(More)
Transforming growth factor-β1 (TGF-β1) signaling and high mobility group A (HMGA1) are known to play essential roles in the progression of breast cancer by inducing epithelial-mesenchymal transition. However, the correlation between TGF-β1 and HMGA1 in breast cancer cell is not yet well understood. In this study, we determined the effects of TGF-β1 on HMGA1(More)
Chemical genetic studies on acetyl-CoA carboxylases (ACCs), rate-limiting enzymes in long chain fatty acid biosynthesis, have greatly advanced the understanding of their biochemistry and molecular biology and promoted the use of ACCs as targets for herbicides in agriculture and for development of drugs for diabetes, obesity and cancers. In mammals, ACCs(More)
Glucocorticoids (GCs) are well known to induce fat distribution, which is consistent with the central adiposity phenotype seen in Cushing's syndrome. GCs have been proposed to be both adipogenic and lipolytic in action within adipose tissues. Different adipogenic and lipolytic effects between subcutaneous adipose tissue (SAT) and visceral adipose tissue(More)
The purpose of this study is to explore the role of hypoxia on the invasion and metastasis of laryngeal carcinoma. The invasion and migration ability of laryngeal cancer SCC10A cell was detected by transwell assay. Western blot was applied to analyze the expression of EMT-related proteins. Fifty-seven samples from postoperative patients with laryngeal(More)
UNLABELLED Using osteoprotegerin (OPG)-knockout mice, we demonstrated that in vivo the effects of both genistein and 17beta-estradiol (E2) on bone metabolism were completely abolished. In contrast, zoledronic acid could effectively suppress bone resorption and prevent bone loss. INTRODUCTION The anti-resorptive effects of E2 on bone metabolism are(More)
Globular adiponectin (gAd) has anti-atherogenic effects on the vascular wall. Intermittent hyperglycemia induces endothelial cells (ECs) injury but the physiological factors that may protect against ECs damage are largely unknown. In the present study, we investigated the effect of gAd on ECs dysfunction induced by intermittent high glucose. The gAd(More)
The aim of this article is to investigate the effects of Aminoguanidine and vitamin C (VitC) on type IV collagen in diabetic nephropathy rats. Diabetic nephropathy rats were induced by intraperitoneal injection of STZ. Rats were randomly divided into five groups: normal control group (n = 10), diabetes group (n = 10), aminoguanidine group (n = 10), VitC(More)
