Comparative expression of androgen receptor in gonads and brain during different stages of gonadal development in Cirrhinus mrigala

Abstract

Androgens are necessary for normal male phenotype expression, including the initiation and maintenance of spermatogenesis. Many physiological actions of androgens are mediated by the androgen receptor (AR), a member of the nuclear receptor super family. In the present study focused to identify the expression of AR in the gonads and brain of Cirrhinus mrigala. The gene specific primers were used to find out the genes in the brain and gonads of an Indian major carp, C. mrigala. Present finding shows the variations of expression of AR receptor mRNA levels in gonads and brain of this fishes. In the present results suggest the gene expression is sex specifically varied in different developmental stages of gonads in the teleosts fish C. mrigala.
