Characterization of genes exhibiting differential expression profiles during ovarian development is important for understanding reproductive maturation of the giant tiger shrimp (Penaeus monodon). Here, the partial cDNAs of P. monodon cAMP-dependent protein kinase, catalytic subunit 1 (PmPkaC1) and adenylyl cyclase-associated protein 1-like (PmCap1-l) were studied. They were more preferentially expressed in ovaries than testes of cultured juveniles and wild broodstock. PmPkaC1 mRNA in ovaries

However, unilateral eyestalk ablation (the removal of one eyestalk) resulted in a significant reduction of its expression (P<0.05). PmCap1-l was not differentially expressed during ovarian development in wild non-ablated broodstock. It was up-regulated in mature ovaries following eyestalk ablation (P<0.05). The PmCap1-l transcript in each ovarian stage of the former was significantly lower than that of the latter (P<0.05). The levels of ovarian PmPkaC1 and vitellogenin 1 (PmVtg1) treated in vitro with 17-20β-DHP (0.1, 1.0 and 10.0 μg/ml for 24 h) was not significantly different from the control (P>0.05). Nevertheless, the expression of PmCap1-l was increased in ovaries treated with 0.1 and 10 μg/ml 17-20β-DHP at 24 hours post treatment (hpt, P<0.05).
