The neuronal nitric oxide synthase (nNOS) is predominantly expressed in nervous tissues and subject to complex transcriptional controls. To determine the effect of acetylation on nNOS expression, human neuroblastoma SK-N-SH cells were treated with trichostatin A (TSA), a histone deacetylase inhibitor. As a consequence, total and exon 1f-specific nNOS mRNA,(More)
MicroRNAs play important roles in the pathogenesis of diabetic nephropathy (DN). In this study, we found that high glucose upregulated miR-27a expression in cultured glomerular mesangial cells and in the kidney glomeruli of streptozotocin (STZ)-induced diabetic rats. miR-27a knockdown prevented high glucose-induced mesangial cell proliferation and also(More)
With-no-lysine (K) kinase-4 (WNK4) is a serine/threonine protein kinase and plays a crucial role in the regulation of blood pressure and electrolyte homeostasis. Whether or not estrogen, an important regulator of physiologic functions, modulates human WNK4 (hWNK4) gene expression is unknown. In the current study, real-time PCR assay showed that(More)
Forkhead box P3 (FoxP3) expression in papillary thyroid carcinoma (PTC) is associated with resistance to radioiodine treatment. The sodium iodine symporter (NIS) is a plasma membrane glycoprotein, the repression of which may render the tumor refractive to radioiodine therapy. In this study, samples from 90 PTCs as well as 40 normal thyroid tissues were(More)
The generation of hyperglycemia-induced mitochondrial reactive oxygen species (ROS) is a key event in diabetic nephropathy development. The forkhead-box class O1 (FoxO1) and peroxisome proliferator-activated receptor γ co-activator 1α (PGC-1α) proteins are implicated in oxidative stress. We investigated the in vivo association of FoxO1 and PGC-1α in renal(More)
Nitric oxide (NO) plays a dual role in response to neural hypoxia. NO is synthesized by three isoforms of nitric oxide synthase (NOS), among which the neuronal NOS (nNOS) is predominant in the nervous system. Hypoxia-inducible factor-1α (HIF-1α) is a transcription factor that is induced under hypoxic conditions, but its correlation with nNOS remains(More)
Nail patella syndrome (NPS) is an autosomal dominant disorder characterized by nail malformations, patellar apoplasia, or patellar hypoplasia. Mutations within the LMX1B gene are found in 85% of families with NPS; thus, this gene has been characterized as the causative gene of NPS. In this study, we identified a heterozygous microdeletion of the entire(More)
We previously generated a cytochrome P450 4F2 (CYP4F2) transgenic mouse model and demonstrated that overexpressed CYP4F2 and overproduced 20-HETE in the kidneys contribute to the increase of blood pressure in the CYP4F2 transgenic mice with normal salt intake. We currently expect to elucidate a potential mechanism of salt-related hypertension whereby(More)
