سندرم تخمدان پلی کیستیک ((pcos مهمترین علت ناباروری ناشی از عدم تخمک گذاری است. در پروسه درمانی این بیماران، متفورمین برای کاهش هایپرانسولینمی و هایپراندروژنسیم تجویز می شود. عملکرد متفورمین از طریق ژن stk11 صورت می گیرد. از آنجایی که در مطالعات فارماکوژنتیکی بررسی پلی مورفیسم های تک نوکلئوتیدی (snp) ژن هایی که در عملکرد و متابولیسم داروها دخالت دارند حائز اهمیت است، در این طرح به بررسیsnp های ...

BACKGROUND In patients with Peutz-Jeghers syndrome (PJS), causative germline mutations in the LKB1/STK11 gene on chromosome 19p13.3 have been identified. Because of the loss of heterozygosity (LOH) at 19p13.3 in hamartomas and the cancer susceptibility of patients with PJS, LKB1/STK11 is suggested to act as a tumour suppressor. However, the frequency of genetic and epigenetic inactivation of LK...

Metformin is a classical oral antidiabetic drug, often recommended to be the first-choice treatment of type 2 diabetes mellitus (T2DM). Based on the previous research on STK11 and diabetes, we aimed to investigate the distributive characteristic of STK11 rs2075604 polymorphism and the potential influence of STK11 rs2075604 polymorphism on metformin efficacy among Chinese T2DM patients. There wa...

Aim: The STK11 gene, also known as LKB1, encodes for a serine/threonine kinase with growth-suppressing activity, such as inhibition of cell cycle progression, cell growth retardation, apoptotic cell death, and cell polarity control. This study aimed to investigate some properties of the STK11 gene and its product, such as the homologous protein sequences in different species, the common transcr...

STK11 is commonly mutated in lung cancer. In light of recent experimental data showing that specific STK11 mutants could acquire oncogenic activities due to the synthesis of a short STK11 isoform, we investigated whether this new classification of STK11 mutants could help refine its role as a prognostic marker. We conducted a retrospective high-throughput genotyping study in 567 resected non-sq...

A potential tumor suppressor gene, STK11 , encoding a serine threonine kinase, has recently been identified on chromosome 19p13. Germ-line mutations of this gene have been found in patients with Peutz-Jeghers syndrome (PJS). To further investigate the relevance of STK11 mutations in PJS, we analyzed its coding sequence in nine patients and identified two deletions and three missense mutations. ...

The genetic predisposition Peutz-Jeghers Syndrome (PJS) has been shown to be associated with mutations in the serine threonine kinase 11 (STK11) gene but only a proportion of probands have been shown to harbour changes in the gene. The remaining patients were proposed to be either associated with a second PJS gene or they harboured more cryptic mutations within the STK11 gene itself. With the i...

Cryoinjury, or injury caused by extremely low temperatures, can occur in corneal endothelial cells (CECs) and lead to visual impairment. However, the mechanism of cryoinjury in CECs is not clear. The Stk11‑p53 signaling pathway regulates the proliferation and division of cells. Activity of the Stk11‑p53 signaling pathway arrests the cell cycle at the G0/G1 phase and induces apoptosis. In this s...

OBJECTIVE Serine-threonine kinase STK11 catalyzes the AMP-activated protein kinase complex. We tested the hypothesis that a gene variant in STK11 contributes to variation in insulin sensitivity and metformin efficacy. RESEARCH DESIGN AND METHODS We studied the effects of a single nucleotide polymorphism (SNP) (rs8111699) in STK11 on endocrine-metabolic and body composition indexes before and ...
