We previously showed that the proopiomelanocortin (POMC) gene is expressed in the ovary of the frog Rana esculenta , and, to evaluate its mRNA content in frog ovary, we have now developed a sensitive quantitative RT-PCR method. This study provides evidence for the validation of this method and for the effects of captivity and hypophysectomy on POMC gene expression in the ovary of this anuran. Our data indicate that ovarian POMC gene is involved in short-term captivity stress response and seems not influenced by pituitary. These results are discussed taking into account the knowledge of the role played by opioids in stress response; moreover, a local control of POMC gene expression is also suggested. frog; ovary; proopiomelanocortin gene expression; captivity; hypophysectomy
