Background: Breast cancer is one of the most common cancer of women in the world.  Although different genetic alteration has been reported in this malignancy, but P 53 gene  mutations has more frequency. P 53 gene is one of the most important suppressor genes and it  play a central role in breast cancer and detecting of mutations in this gene would be very helpful in understanding of genetic m...

Background Autosomal recessive polycystic kidney disease (ARPKD; OMIM number 263200) is a severe early onset hereditary form of polycystic kidney and liver disease. Case Report In the current study, we present a consanguineous couple with a history of an affected son with polycystic kidney disease (PKD), hepatic failure and epileptic seizures who died at the age of 8 months. Both parents were h...

Mitochondrial DNAs (mtDNAs) has been frequently used as genetic markers for the population genetic studies. In this study we used chum salmon (Oncorhynchus keta) from Korea, Japan andAmerica, and compared their mitochondrial NADH dehydrogenase subunit 3 (ND3) genes by DNA sequence analysis. Sequence variation was studied in the ND3 among total 11 individuals from three populations. The ND3 gene...

Aicardi-Goutieres syndrome (AGS) is an inflammatory genetic disease inherited in an autosomal recessive manner. Common features of this disease are encephalopathy, splenomegaly and hepatomegaly, muscle stiffness, irritability, unstoppable crying, seizures and dilation in growth. According to previous studies, primary genes responsible for this Syndromes are as followed: TREX 1, RNASEH2A, RNASEH...

Background and Aims: lamivudine is amongst the antiviral for drug chronic hepatitis B treatment. During therapy with lamivudine, variants may emerge with YMDD mutation in the reverse transcriptase (RT) region of polymerase gene. This mutation might have a role in drug resistant for HBV. Materials and Methods: HBV DNA extraction from serum sample of 88 patients, were subjected to nested PCR for ...

Background: The immune antigen of Bacillus anthracis is a protein that can attach to the surface receptor of all human cells. At the surface of cancer cells, there is a receptor that activates the uPA (Urokinase plasminogen) that do not exist in normal human cells. Objectives: The aim of this study was changing the location of the attachment of the PA gene by a dir...

mara activates two membrane dependent mechanisms of resistance to different antibiotics, such as ciprofloxacin and tetracycline, including promotion of outflux and inhibition of influx of antibiotics. thus, mara causes multiple antibiotic resistance phenotype. the activation of these mechanisms needs overexpression of mara. this could happen through mutation in marr. thus, the aim of this study...

zebra fish were exposed to environmentally relevant concentration of pesticides and metals fora period of 14 days. the individual and the combined toxicity of pesticides and metals were studied. damage caused to the dna and induction of mutation in the gadd45β gene was investigated in this study. the present investigation revealed that exposure of zebra fish to pesticides and metals induced dna...

in india, holstein and its crosses are being used extensively in breeding programmes and all these breeding bulls are screened for autosomal recessive genes. blood samples are collected in ethylenediaminetetraacetic acid (edta) coated tubes and dna was isolated by using phenol-chloroform method. polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) wereperformed by using...
