Upregulation of PCP4 in human aldosterone-producing adenomas fosters human adrenocortical tumor cell growth via AKT and AMPK pathway.

Primary aldosteronism (PA) is characterized by aldosterone hypersecretion and adrenal hyperplasia and ranks as one of the most common causes of secondary hypertension. However, the molecular mechanism involved in adrenal hyperplasia and tumorigenesis is largely unknown. Dysregulation of Purkinji cell protein 4 (PCP4) is involved in the development and progression of neoplasia and aldosterone secretion, but little is known about the effect of PCP4 on human adrenocortical tumorigenesis.

Endocrinal description of two Chinese Kennedy's disease pedigrees.

Kennedy's disease (KD), also known as X-linked spinal and bulbar muscular atrophy (SBMA), is caused by the expansion of cytosine-adenine-guanine (CAG) repeats in the first exon of the androgen receptor (AR) gene. KD is a late-onset neural-endocrinal disease that is characterized by the degeneration of motor neurons in the brainstem and spinal cord. In addition, partial androgen insensitivity is an important manifestation of KD.

Effect of Saxagliptin on Circulating Endothelial Progenitor Cells and Endothelial Function in Newly Diagnosed Type 2 Diabetic Patients.

Endothelial dysfunction is associated with the risk of cardiovascular complications in diabetic patients. Endothelial progenitor cells (EPCs) and flow-mediated dilation (FMD) are common markers of endothelial function. In this study, we aim to investigate whether the DPP-4 inhibitor saxagliptin modulate EPCs number and FMD in newly diagnosed, treatment-naive type 2 diabetic patients.

A new mutation in the CSB gene in a Chinese patient with mild Cockayne syndrome.

Cockayne syndrome (CS) is a rare autosomal recessive genetic disease characterized by growth failure and progressive neurological degeneration. Here we report a mild form of CS patient who was homozygous for the C526T transition resulting in a new nonsense mutation, which converts Arg176 to a stop codon.

Decreased LINE-1 methylation levels in aldosterone-producing adenoma.

Purpose: Abnormal global DNA methylation levels are associated with many diseases. In this study, we examined long interspersed nuclear elements-1 (LINE-1) methylation as a biomarker for abnormal global DNA methylation and aldosterone-producing adenoma (APA).

Methods: Tissues from 25 APA and 6 normal adrenal glands (NAs) were analyzed for LINE-1 methylation by real-time methylation-specific polymerase chain reaction.
