Diagnosis and genetic analysis of a case of Waardenburg syndrome type 2 with hypogonadotropic hypogonadism caused by gene deletion.

Hypogonadotropic hypogonadism (HH) is a disease defined by dysfunction of the hypothalamic- pituitary-gonadal hormone axis, leading to low sex hormone levels and impaired fertility. HH with anosmia or hyposmia is known as Kallmann syndrome (KS). Waardenburg syndrome (WS) is a rare autosomal dominant genetic disorder characterized by sensorineural hearing loss and abnormal pigmentation.

Association of Interleukin-6 -174G/C Polymorphism with the Risk of Diabetic Nephropathy in Type 2 Diabetes: A Meta-analysis.

Previous studies reported the association between interleukin-6 (IL-6) -174G/C gene polymorphism and the risk of diabetic nephropathy in type 2 diabetes mellitus (T2DN). However, the results remain controversial. In the present study, we conducted a meta-analysis to further examine this relationship between IL-6-174G/C gene polymorphism and T2DN.

Liraglutide protects β-cell function by reversing histone modification of Pdx-1 proximal promoter in catch-up growth male rats.

Aims: Catch-up growth after a period of nutritional deprivation in adulthood is related to the onset of metabolic disorders. This process involves chromatin remodelling of the Pdx-1 gene in pancreas. The objective of this study was to determine the chromatin remodelling mechanism of GLP-1 analogue Liraglutide upon Pdx-1 in catch-up growth rats in vivo and in vitro.

Insulin sensitizers improve the GLP-1 secretion and the amount of intestinal L cells on high-fat-diet-induced catch-up growth.

Objective: The aim of this study was to investigate whether insulin resistance can result in impaired glucagon-like peptide (GLP)-1 secretion and to determine whether insulin-sensitizing drugs could improve the secretion of GLP-1 in catch-up growth rats.

Methods: Male Sprague Dawley rats were used to establish a catch-up growth model. At the end of weeks 6 and 14, these rats were euthanized to measure energy intake, body weight, plasma triacylglycerol, and nonesterified fatty acid.
