androgen receptor regulates testes organization and oocyte maturation in zebrafish

P-231: Androgen Receptor Gene Expression in Azoospermia Men

Background: Androgens are critical steroid hormones in progression of spermatogenesis process and determine the male phenotype that their actions are mediated by the androgen receptor (AR), a member of the nuclear receptor superfamily. In the Androgen receptor, transactivation domain encoded by exon 1, DNA binding domain encoded by exons 2 and 3, hinge region encoded by part of exon 4, and C-te...

P-121: Assessment of Microtubule and Nuclear Status at Different Intervals of Bovine In Vitro Oocyte Maturation

Background: Mammalian oocyte undergoes a series of structural nuclear modulations during maturation in order to obtain full competence to support fertilization and early embryonic development. Microtubules are major cytoskeleton components and have pivotal modulators for chromosomal movement, and it has been shown that partial or immature spindle organization may compromise correct ploidy of th...

P-84: Characterization of Androgen Receptor Structure and Nucleocytoplasmic Shuttling of the Rice Field Eel

Background: Androgen receptor (AR) plays a critical role in prostate cancer and male sexual differentiation.Mechanisms by which AR acts and regulations of AR nucleocytoplasmic shuttling are not understood well. Materials and Methods: Degenerate PCR and RACE Cloning of AR Gene; Phylogenetic Analysis and Molecular Modeling;Real-time Fluorescent Quantitative RT-PCR; Northern Blot Hybridization;In ...

P-118: Stepwise Morphometric Changesduring In Vitro Maturation of Goat Oocytein Relation with Nuclear Remodeling and Developmental Competencee

Background: Successful in vitro maturation (IVM) of oocytes is an important step for production of livestock through assisted reproductive techniques including somatic cell nuclear transfer (SCNT). Obtaining an optimal duration for maturation of oocyte is essential, since over exposure to maturation medium results in oocyte aging, while under exposure leads to production of immature incompetent...
