P-131: The Study of Nitric Oxide Synthase 3 (NOS3) 4a4b Gene Polymorphism in Iranian Infertile Men with Varicocele

Background Varicocele is an abnormal dilation and tortuosity of veins of pampiniform plexus that drains the testis and causes an important change in semen.This abnormality is often one of the most common risk factors for male infertility. The aim of this study was to investigate the relationship between nitric oxide synthase 3 (NOS3) 4a4b (rs61722009) gene polymorphism, as a common genetic fact...

Genetic distinctiveness of endangered dwarf blue sheep (Pseudois nayaur schaeferi): evidence from mitochondrial control region and Y-linked ZFY intron sequences.

To elucidate the controversial systematic relationship of blue sheep (Pseudois nayaur) and endangered dwarf blue sheep, we sequenced part of the mtDNA control region and Y-linked ZFY intron, and carried out phylogenetic analyses. Mitochondrial results revealed that the dwarf blue sheep is a strongly supported monophyletic group, with an average of 12.21% sequence divergence from the blue sheep....

Comparative molecular phylogeny and evolution of sex chromosome DNA sequences in the family Canidae (Mammalia: Carnivora).

To investigate the molecular phylogeny and evolution of the family Canidae, nucleotide sequences of the zinc-finger-protein gene on the Y chromosome (ZFY, 924-1146 bp) and its homologous gene on the X chromosome (ZFX, 834-839 bp) for twelve canid species were determined. The phylogenetic relationships among species reconstructed by the paternal ZFY sequences closely agreed with those by mtDNA a...

P-122: The Effect of Beta Globin Intron on Human LH Hormone Expression in CHO Cells

Background Luteinizing hormone (LH) is a heterodimeric glycoprotein composed of alpha and beta subunits.This hormone is secreted from the pituitary gland. LH, in women triggers Menstrual cycle and ovulation. In men, LH stimulates production of testosterone, which plays a specialized role in sperm production. Up to day, LH hormone have produced in different ways such as codon optimization and al...
