Background: We explored the effect of vitamin D receptor gene (VDR) polymorphisms in response to PEG-IFN treatment in Egyptian chronic hepatitis B (CHB) patients. Methods: Two hundred hepatitis B virus (HBV) patients (42.3±10.7 years) on PEG-IFN α-2a (180 μg /kg for 48 weeks) and one hundred control subjects (37.3 ±12 years) were enrolled in the study. Vitamin D levels a...

Tuberculosis is a vagarious infectious disease that generally affects the lungs. Accordingly, in some cases, it can also affect the liver and kidney. Host genetic may affect tuberculosis caused by bacillus Mycobacterium tuberculosis. The main risk factors for the disease are a weakened immune system because of diabetes, some cancers, HIV/AIDS, severe kidney disease, cancer treatment, a...

objectives thus, the present study aimed to determine if fas and fasl promoter polymorphisms are associated with the clinical outcome of hbv infection. patients and methods dna samples were obtained from the infected individuals including chronic carrier (n = 50), chronic hepatitis (n = 50), cirrhosis (n = 25), naturally recovered (n = 26) and compared with those of their matched healthy contro...

background: inflammatory bowel disease, an autoimmune disease, has two clinical manifestations including crohn’s disease and ulcerative colitis (uc). il-17 has been the target of intensive research in autoimmune diseases. the influence of toll like receptor 4 (tlr-4) gene polymorphisms on il-17 production has also been revealed in uc patients and tissue inflammation in mice. objectives: to inve...

Increasing alcohol consumption by women of childbearing age contributes to more frequent cases fetal spectrum disorder. The cause the syndrome is exposure, particularly what referred as high prenatal exposure. Low metabolic activity enzymes shifts burden ethanol removal maternal metabolism. One factors influencing pathogenesis FASD genetic background. It can determine rate elimination ethanol, ...

Functional polymorphisms that alter gene expression and mRNA processing appear to play a critical role in shaping human phenotypic variability. Intensive studies on polymorphisms affecting drug response have revealed multiple modes of altered gene function, frequently involving cis-acting regulatory sequence variants. Experimental and in silico methods have advanced the search for such polymorp...

background vegf gene has been reported to be related with many diseases and recurrent pregnancy loss in various studies. vegf polymorphisms are risk factors for pregnancy losses, and generally studies report only women’s genetic analyses. to evaluate the association between vegf a c405g, c460t, c936t and c2578a polymorphisms and spontaneous abortion, we studied the genotypes of spontaneously ab...

background: normal tissue toxicity continues to remain as a major challenge for radiation oncologists for delivering the total dose to the tumour cells in cancer patients. cellular, molecular and plasma based early biomarkers to predict the overreactions and non-overreactions of normal tissue toxicity before the initiation of radiotherapy can be valuable for personalised treatment. the aim of t...

background: exposure to endogenous hormones such as estrogen is known as a lifetime breast cancer (bc) risk factor. polymorphisms in genes that are involved in the steroidogenic process, such as cytochrome p450c17alpha ( cyp17) , affect individuals’ susceptibility to bc. in iran, the highest incident of bc is among young women. this study aimed to find prevalence of single nucleotide polymorphi...
