The aim of the present study was to detect the combined effect of negative life events and the norepinephrine transporter (NET) gene on the development of major depression (MD) in a Chinese population. We recruited 388 unrelated patients affected with MD and 388 healthy controls in this study. The score of 32 was used as a cut-off value for grouping the(More)
BACKGROUND/AIMS Nuclear factor erythroid 2-related factor 2 (Nrf2) is a positive regulator of the expression of antioxidant genes. This study is aimed at examining the effect of tert-butylhydroquinone (tBHQ), an activator of Nrf2, on hyperglycemia-related diabetic nephropathy. METHODS CD-1 mice were induced with streptozotocin and treated with 1% tBHQ, or(More)
Breast cancer is the most common malignancy with the highest incidence among women in the world. Metastasis is the major reason for breast cancer-related deaths. The precise molecular circuitry that governs the metastasis process has not been completely understood. Discoveries of microRNAs (miRNAs) open a new avenue for cancer metastasis research. It has(More)
In this study, β2-AR level was found to be up-regulated in MCF-7 cells overexpressing Her2 (MCF-7/Her2). Correlation of β2-AR level with Her2 status was demonstrated in breast cancer tissue samples. Constitutive phosphorylation of ERK, mRNA expression up-regulation of catecholamine-synthesis enzymes, and increased epinephrine release were detected in(More)
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)
Reactive oxygen species (ROS) play an important role in the pathogenesis of diabetic nephropathy. Nuclear factor erythroid 2-related factor 2 (Nrf2) can up-regulate the expression of antioxidant genes and protect cells from oxidative damage. The current study is aimed at examining the effect of modulation of Nrf2 expression on high glucose-induced oxidative(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)
Podocyte apoptosis contributes to the pathogenesis of diabetic nephropathy (DN). However, the mechanisms that mediate hyperglycemia-induced podocyte apoptosis remain poorly understood. Recent findings indicate that the disruption of the cytoskeleton is related to the podocyte apoptosis. In the present study, we investigated the involvement of nestin, an(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)
