Approximately 10% of all cancers are considered hereditary and are primarily caused by germline, high penetrance mutations in cancer predisposition genes. Although most cancer predisposition genes are considered molecularly heterogeneous, displaying hundreds of different disease-causing sequence alterations, founder mutations have been identified in certain populations. In some Latin American c...

بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...

The molecular diagnostics of genetically conditioned disorders is based on the identification of the mutations in the predisposing genes. Hereditary cancer disorders of the gastrointestinal tracts are caused by mutations of the tumour suppressor genes or the DNA repair genes. Occurrence of recurrent mutation allows improvement of molecular diagnostics. The mutation spectrum in the genes causing...

BACKGROUND Helicobacter pylori is associated with inflammation of different areas, such as the duodenum and stomach, causing gastritis and gastric ulcers leading to lymphoma and cancer. Pathogenic islands are a type of clustered mobile elements ranging from 10-200 Kb contributing to the virulence of the respective pathogen coding for one or more virulence factors. Virulence factors are molecule...

Similar to seemingly maladaptive genes in general, the persistence of inherited cancer-causing mutant alleles in populations remains a challenging question for evolutionary biologists. In addition to traditional explanations such as senescence or antagonistic pleiotropy, here we put forward a new hypothesis to explain the retention of oncogenic mutations. We propose that although natural defens...

Background and Aims: Helicobacter pylori is the main cause of various gastroduodenal diseases. It is estimated that app roximately, more than half of the adult population in developed countries and 90% of people in developing countries infected with H. pylori. H. pylori infection may be related to Genetic of virulence factors and environmental factors. The aim of this study was to assess of fre...

Introduction: Colon cancer has spread to developed countries. Probiotic bacteria can play an important role in reducing cancer and treating colon cancer. The aim of this study was to determine the effect of adjacent bovine Lactobacillus rhamnose culture on the expression of casp3 and bax genes in cancer cell.   Materials & Methods: In this experimental study after bacterial culture, supernatan...

background:the zinc-finger x linked (zfx) gene encodes a transcription factor that acts as a regulator of self-renewal of stem cells. due to the role of zfx in cell growth, understanding zfx protein-protein interactions helps to clarify its proper biological functions in signaling pathways. the aim of this study is to define zfx protein-protein interactions and the role of zfx in cell growth. m...

Introduction: Glutathione S-tarnsferases (GST) gene family is one of the enzymes which is responsible for detoxifying mutagens and Carcinogens chemicals. People with null genotype of GSTM1 and GSTT1 genes are at higher risk of developing cancer, especially those who are related to smoking. The goal of this study was investigating the rate of glutathione S-transferase T1 and M1 genes deletion an...

Extract: A single inherited mutant gene may be enough to cause a very high cancer risk. Single-mutation cases have provided much insight into the genetic basis of carcinogenesis, but they are relatively rare and account for only a small fraction of all cancers. Examples include mutation to the APC gene, causing early onset colon cancer in the syndrome familial adenomatous polyposis (tumorous po...
