b ackground: the main goal of present study was to detect polymorphism in msp-1 gene which is a major blood stage candidate for vaccine in plasmodium vivax by single strand conformational poly- morphism-polymerase chain reaction (sscp-pcr). m ethods: during 2008 to 2010 fifty samples were collected from iranian patients with p. vivax in hormozgan province, southern iran. all of the samples were...

Promoter-proximal RNA polymerase II (Pol II) pausing is implicated in the regulation of gene transcription. However, the mechanisms of pausing including its dynamics during transcriptional responses remain to be fully understood. We performed global analysis of short capped RNAs and Pol II Chromatin Immunoprecipitation sequencing in MCF-7 breast cancer cells to map Pol II pausing across the gen...

Objective. To compare the difference of imprinting status of insulin-like growth factor II (IGF-II) gene in villus between normal embryo development group and abnormal embryo development group and to investigate the relationship between karyotype and the imprinting status of IGF-II gene. Methods. A total of 85 pregnant women with singleton pregnancy were divided into two groups: one with abnorm...

Polymorphisms in 5’-flanking region of prolactin (PRL), exon 2 and exon 5 of prolactin receptor (PRLR) genesand its association with growth and egg traits were examined in breeder hens of Mazandaran native fowlsbreeding station. A single nucleotide polymorphism at site C-2402T and a 24 bp nucleotide sequence insertionat situation -382 in 5’-flanking regions of PRL gene were id...

Previously, we have reported that the coronary reactive hyperemic response was reduced in adenosine A2A receptor-null (A2AAR?/?) mice, and it reversed by soluble epoxide hydrolase (sEH) inhibitor. However, is unknown aortic vascular response, therefore, hypothesized A2AAR-gene deletion mice affects adenosine-induced increase sEH A1 receptor (A1AR) activities. A2AAR?/? showed an sEH, AI AR CYP45...

Peptides encoded by the urocortin II (Ucn II) gene were recently identified as new members of the corticotropin-releasing factor (CRF) family. Ucn II is a specific ligand for the type 2 CRF receptor. Using RT-PCR, DNA sequencing, and immunofluorescence staining, we report the expression of Ucn II mRNA in several human and mouse (m) neuronal cell lines. Using these neuronal cell lines, we provid...

The study of mice with targeted disruptions of angiotensin receptor genes has provided new insights into the roles of the individual receptor subtypes, i.e., AT(1A), AT(1B), and AT(2), in growth, development, and the regulation of blood pressure.

The intracellular mechanism by which interferon-gamma induces the expression of class II major histocompatibility complex (MHC) antigen in nonlymphoid cells is not clear. The effect of recombinant rat interferon-gamma (IFN-gamma), and cycloheximide on the expression of class II MHC gene was studied using the techniques of immunocytochemical staining and northern blot analysis. IFN-gamma induced...

conclusions using the pcr-rflp method, three distinctive h. pylori caga genotypes were detected in antral biopsies. genotype i, which was predominant among the isolates, was significantly associated with gastritis. however, the data showed that caga genotype iii may play a role in duodenitis and duodenal ulcers in patients infected with h. pylori. patients and methods a total of 161 gastric bio...

The appropriate genetic potential of an athlete or prospective determines the development their future performance and achievement reduces risk pathological conditions such as overtraining. This study aimed to determine genotype variation thought play a role in differences exercise results explosive power performance, namely ACE gene. research method used cross-sectional design describe relatio...
