BACKGROUND About 10% of infertilities with obstructive azoospermia are congenital and caused by CF gene mutations. M469I mutation was observed for the first time in Taiwanese patients. This mutation not only causes CF, but also may be the origin of infertility too. OBJECTIVE In this study, we aimed in designing a rapid, reliable RFLP-PCR procedure for detection of M469I mutation. The correlat...

We have characterized a novel, captured and fully functional viral interleukin (IL)-10 homologue ((OvHV)IL-10) from the gammaherpesvirus ovine herpesvirus 2. Unlike IL-10 homologues from other gammaherpesviruses, the (OvHV)IL-10 peptide sequence was highly divergent from that of the host species. The (OvHV)IL-10 gene is unique amongst virus captured genes in that it has precisely retained the o...

background: leishmaniasis is a protozoan disease cause by leishmania genus. anthroponotic and zoono­tic cutaneous leishmaniasis are endemic in iran. the aim of this study was to identify the causative agent of cutaneous leishmaniasis by mini-exon gene in five regions of khuzestan province, southwest of iran. methods: from 2007 to 2008 in this cross-sectional study, cutaneous samples were collec...

The exon-junction complex (EJC) deposited on a newly spliced mRNA plays an important role in subsequent mRNA metabolic events. Here we show that an EJC core heterodimer, Y14/Magoh, specifically associates with mRNA-degradation factors, including the mRNA-decapping complex and exoribonucleases, whereas another core factor, eIF4AIII/MLN51, does not. We also demonstrate that Y14 interacts directly...

The multiprotein exon junction complex (EJC) that is deposited upstream of spliced junctions orchestrates downstream events in the life of a metazoan mRNA, including its surveillance via the nonsense-mediated decay (NMD) pathway. However, the mechanism by which the spliceosome mediates EJC formation is not well understood. We show that human eIF4G-like spliceosomal protein (h)CWC22 directly int...

Background & Aims: Thyroid cancer is the most common endocrine malignancy. Medullary thyroid carcinoma (MTC) is an aggressive malignant tumor arising from parafollicular cells of the thyroid. MTC occurs in hereditary (25%, hMTC) or sporadic (75%, sMTC) forms. The hMTC form has an autosomal dominant inheritance. RET proto-oncogene mutations, especially the 10, 11, and 16 exones, are associated w...
