BACKGROUND Stress, anxiety and depression can cause complex physiological and neuroendocrine changes, resulting in increased level of stress related hormone catecholamine, which may constitute a primary mechanism by which physiological factors impact gene expression in tumors. In the present study, we investigated the effects of catecholamine stimulation on(More)
Diabetic nephropathy is a complex and poorly understood disease process, and our current treatment options are limited. It remains critical, then, to identify novel therapeutic targets. Recently, a developmental protein and one of the bone morphogenetic protein antagonists, Gremlin, has emerged as a novel modulator of diabetic nephropathy. The high(More)
Podocytes are terminally differentiated epithelial cells lacking the ability to proliferate. The loss of podocytes is a hallmark of progressive kidney diseases, including diabetic nephropathy (DN). Endoplasmic reticulum stress (ERS)-induced apoptosis is involved in a number of pathological conditions, including DN. The aim of the present study was to(More)
Transforming growth factor-β1 (TGF-β1) plays an important role in the pathogenesis and progression of chronic kidney disease. Connective tissue growth factor (CTGF) is a critical fibrogenic mediator of TGF-β1. Mammalian sirtuin 1 (Sirt1) is reported to attenuate renal fibrosis by inhibiting the TGF-β1 pathway. This study was designed to detect whether the(More)
Renal tubular epithelial cells (RTEC) apoptosis, which plays a key role in the pathogenesis and progression of diabetic nephropathy (DN), is believed to be contributive to the hyperglycemia-induced kidney failure, though the exact mechanisms remain elusive. In this study, we investigated how inhibition of c-Src/p38 MAPK pathway would affect RTEC apoptosis.(More)
DL-3-n-butylphthalide (NBP) is a therapeutic drug used for ischemic stroke treatment. Here, we investigated the impact of NBP on the development of rat diabetic cataract induced by intraperitoneal injection of streptozotocin (STZ). NBP was then administrated by oral gavage for nine weeks. Cataract development was monitored through ophthalmoscope(More)
Type 2 diabetes is characterized by hyperglycemia and deregulated lipid metabolism with increased plasma non-esterified fatty acids (NEFA). Apoptosis of glomerular cells is a hallmark in diabetic glomerulosclerosis. Fatty acid-binding protein 4 (FABP4), a carrier protein for fatty acids, has been linked to diabetes and diabetic nephropathy (DN). Here we(More)
The dysregulation of cholesterol metabolism and inflammation plays a significant role in the progression of diabetic nephropathy (DN). Anthocyanins are polyphenols widely distributed in food and exert various biological effects including antioxidative, anti-inflammatory, and antihyperlipidemic effects. However, it remains unclear whether anthocyanins are(More)
In the present study, we demonstrated the cell cycle periodicity of Erbin expression with the maximal expression of Erbin in G2/M phase. A significant increase in Erbin promoter activity was observed in G2/M phase-synchronized cells. Sequence analysis revealed a c-Myb site in the core promoter region of Erbin. Mutagenesis of c-Myb consensus sequences(More)
OBJECTIVE The personality trait of neuroticism is a risk factor for major depressive disorder (MDD), but this relationship has not been demonstrated in clinical samples from Asia. METHODS We examined a large-scale clinical study of Chinese Han women with recurrent major depression and community-acquired controls. RESULTS Elevated levels of neuroticism(More)
