Lynch syndrome is an inherited cancer-predisposing disorder caused by germline mutations in the DNA mismatch repair (MMR) genes but there is a high degree of variability in cancer risk observed among carriers, suggesting the existence of modifying factors. Our aim was to investigate variants within the hTERT gene as a potential colorectal cancer (CRC) risk modifier for MMR gene mutation carrier...
In an increasing proportion of cases, hepatocellular carcinoma (HCC) develops in patients with nonalcoholic fatty liver disease (NAFLD). Mutations in telomerase reverse transcriptase (hTERT) are associated with familial liver diseases. The aim of this study was to examine telomere length and germline hTERT mutations as associated with NAFLD-HCC. In 40 patients with NAFLD-HCC, 45 with NAFLD-cirr...
background human telomerase reverse transcriptase (htert) has become an ideal target for development of anticancer therapy. small interfering rnas (sirnas) are very powerful reagents for gene silencing and show promise for cancer gene therapy. however, only a small number of sirnas have been demonstrated to be effective. for gene therapy targeting htert, it is essential to develop a robust syst...
Background: Human telomerase reverse transcriptase (hTERT) promoter mutations are common genetic events in bladder cancer (BC) and have been recognized as potential biomarkers for BC diagnosis prognosis. Detection of TERT urine-based tests has previously reported to detect primary recurrent BC. This study was planned evaluate hTERT both biopsies urines from patients assess the interest usefulne...
زمینه: سرطان پستان شایع ترین نوع سرطان در زنان است. چاقی از جمله عوامل خطر شناخته شده برای این سرطان است که با تولید آدیپوسیتوکین ها می تواند نقش مستقیمی در بروز سرطان داشته باشد. از طرفی برای شروع و پیشرفت سرطان، فعالیت آنزیم تلومراز ب ه خصوص بیان ژن زیر واحد کاتالیتیک آن (htert) ، ضروری به نظر می رسد. هدف: مطالعه به منظور تعیین ارتباط بین درجههای مختلف چاقی و آدیپوسیتوکینها با بیا...
lentinan a polysaccharide from medicinal mushroom i.e lentinus, has been known to have anticancer properties. telomerase activity is not observed in normal healthy cells, whereas in cancerous cells telomerase expression is high. telomerase represents a promising cancer therapeutic target. we investigated the inhibitory effect of lentinan on telomerase reverse transcriptase gene (htert) which is...
کموتراپی، امروزه از رایج ترین استراتژی های درمانی سرطان می باشد. با این حال، عود مجدد و تاثیرات ثانویه شدید در این شیوه درمانی، نیاز به طراحی، تولید و کشف داروهای موثر تر با خطرات جانبی کمتر را مشهود می سازد. کورکومین با نام علمی diferuloylmethane، پلی فنلی زردرنگ و جزء فعال اصلی گیاه زردچوبه یا curcuma longa می باشد. این ماده از طریق مهار چندین مسیر سیگنالینگ سلولی قادر به جلوگیری از تکثیر، ته...
Telomerase reverse transcriptase (hTERT) represents an attractive target for cancer immunotherapy because hTERT is reactivated in most human tumors. A clinical trial was initiated in which hTERT mRNA-transfected dendritic cells (DC) were administered to 20 patients with metastatic prostate cancer. Nine of these subjects received DC transfected with mRNA encoding a chimeric lysosome-associated m...
Background and Aim: Chronic Myelogenous Leukemia (CML) is a clonal hematopoietic stem cell disorder characterized by a translocation between chromosome 9 and 22 called Philadelphia Chromosome. Telomerase- essential enzyme that adds telomeric repeats into the telomeres- maintains integrity of chromosomal ends. Most normal somatic cells do not express hTERT (catalytic subunit of telomerase) but ...
OBJECTIVE We attempted to reveal the changes of the human telomerase reverse transcriptase (hTERT) alternative splicing pattern in gastric carcinogenesis. METHODS Three alternative splicing sites (alpha, beta, gamma) were selected and designed PCR primer. The expression of 8 hTERT alternative splicing variants (ASVs) in normal gastric mucosa, precancerous lesions and gastric cancer were detec...
