“…It has been revealed that progesterone could induce ovarian maturation and spawning in Metapenaeus ensis (Yano, 1985), and 17α-hydroxyprogesterone could stimulate vitellogenin synthesis in Penaeus japonicus (Yano, 1987). In this paper, knockdown of PcC1q-like caused significant decrease of progesterone content in the ovary, suggesting that PcC1q-like may be correlated with the synthesis of ovarian progesterone.…”

“…TNF has been revealed to be related to progesterone synthesis (Bobe and Goetz, 2000), and progesterone plays important roles in oocyte development of crustaceans (Yano, 1987;Quinitio et al, 1994). To learn whether PcC1q-like knockdown may affect progesterone synthesis, we determined the progesterone concentration in the ovaries after 24 h of the second injection of dsC1q-like.…”

“…This suggested that gonad-inhibiting hormone, a polypeptide hormone synthesized in the eyestalk (Treerattrakool et al, 2008), has a prominent effect on the transcription of PmBR-C Z6. Accordingly, the expression level of this gene may be used as molecular indicator for following the progression of ovarian development and the final maturation of P. monodon broodstock as a consequence of maturation-inducing feed (Meunpol et al, 2005) and/or exogenous hormonal administration (e.g., progesterone and 17-β-estradiol; Yano, 1987;Yano and Hoshino, 2006;Meunpol et al, 2007).…”

ABSTRACT. Broad-Complex (BR-C) is an early ecdysone-responsive gene encoding a family of zinc-finger transcription factors that function during metamorphosis in insects. We identified two full-length cDNAs of BR-C Z6 in the giant tiger shrimp (Penaeus monodon). They were 2422 and 2060 bp in length, containing open reading frames of 1440 and 1443 bp, corresponding to polypeptides of 479 and 480 amino acids, respectively. Tissue distribution analysis indicated that PmBR-C Z6 was abundantly expressed in hemocytes and ovaries in juveniles. In broodstock, PmBR-C Z6 was constitutively expressed in all tissues BR-C Z6 in ovaries of Penaeus monodon examined, and the highest expression was observed in ovaries. The expression of PmBR-C Z6 in ovaries was significantly greater than in testes in both juveniles and broodstock of P. monodon. Quantitative real-time PCR indicated that the expression level of PmBR-C Z6 was significantly down-regulated in stages II and III of ovaries in intact wild broodstock and returned to the basal level in stage IV ovaries and after spawning. In eyestalk-ablated broodstock, PmBR-C Z6 was significantly up-regulated in stage IV (mature) ovaries. Moreover, the expression level of PmBR-C Z6 in vitellogenic, early cortical rod and mature (stages II-IV) ovaries of eyestalk-ablated broodstock was greater than that of the same ovarian stages in intact broodstock. In situ hybridization revealed that PmBR-C Z6 transcripts were localized in oogonia and cytoplasm of previtellogenic and vitellogenic oocytes of both wild intact and eyestalkabated broodstock. The effects of 20-hydroxyecdysone on expression of PmBR-C Z6 were examined. The expression level of PmBR-C Z6 in ovaries of juvenile P. monodon was significantly increased at 168 h postinjection. Taken together, these findings indicate that PmBR-C Z6 plays an important role in ovarian development of P. monodon.

“…The in vivo stimulation of vitellogenesis in marine penaeid prawns by progesterone (Kulkarni et al, 1979;Van Herp and Payen, 1991) and in fresh water species by progesterone (Sarajoni et al, 1985) or by estrone and 17β-estradiol (Sarajoni et al, 1986) was reported. Also, 17α-hydroxyprogesterone was demonstrated to stimulate vitellogenesis in marine penaeids (Nagabhushanam et al, 1980;Yano, 1987) and to increase oocyte diameter in Litopenaeus vannamei (Tsukimura and Kamemoto, 1988). Nevertheless, other researchers reported lack of response to either 17α-hydroxyprogesterone or 17β-estradiol as vitellogenin stimulating hormones in Penaeus esculentus (Koskela et al, 1992).…”

“…It was also hypothesised that this VSOH could be a steroid hormone (Van Herp and Payen, 1991). A putative role of VSOH has been attributed to several steroid hormones such as progesterone (Kulkarni et al, 1979;Yano, 1985), 17α-hydroxyprogesterone (Nagabhushanam et al, 1980;Tsukimura and Kamemoto, 1988;Yano, 1987) and 17β-estradiol (Couch et al, 1987;Fairs et al, 1990).…”

SUMMARY: Radioimmunoassay (RIA) was applied to identify selected metabolites obtained in in vitro incubations of ovarian and hepatopancreatic tissues from female Marsupenaeus japonicus in previtellogenic and vitellogenic maturation stages. Depending on the precursors used, progesterone, 17α-hydroxyprogesterone or testosterone, it was possible to observe the presence of several enzymatic activities through metabolites detected in incubations. The present study provides evidence that the ovary of the shrimp M. japonicus is capable of synthesising 17β-estradiol from progesterone, evidencing the presence of 17α-hydroxylase, C 17 -C 20 lyase, 17β-hydroxysteroid dehydrogenase (17β-HSD) and aromatase. Enzymatic activities of aromatase, 3β-HSD and 17α-hydroxylase were detected in hepatopancreas, but not that of C 17 -C 20 lyase. These results suggest that 17β-estradiol could be the vitellogenesis stimulating ovarian hormone (VSOH), and together with former in vivo and in vitro studies this leads us to propose that in fact there may be a physiological role for steroid hormones in the maturation cycle of crustaceans.Key words: crustacean, decapods, hepatopancreas, hormones, maturation, ovary, reproduction, steroids. RESUMEN: METABOLISMO IN VITRO DE HORMONAS ESTEROIDES EN EL OVARIO Y EN EL HEPATOPÁNCREAS DEL LANGOSTINO MAR-SUPENAEUS JAPONICUS (CRUSTACEA, PENAEIDAE). -Se utilizó el radioinmunoensayo (RIA) para identificar los metabolitos seleccionados obtenidos en incubaciones in vitro del ovario y del hepatopáncreas de hembras en estado de maduración previtelogénico y vitelogénico de Marsupenaeus japonicus. Dependiendo del precursor utilizado: progesterona, 17α-hidroxiprogesterona o testosterona fue posible observar la presencia de diversas actividades enzimáticas a través de metabolitos detectados en las incubaciones. El presente estudio demuestra que el ovario del langostino M. japonicus es capaz de sintetizar 17β-estradiol a partir de progesterona y pone en evidencia la presencia de 17α-hidroxilasa, C 17 -C 20 liasa, 17β-hidroxiesteroide deshidrogenasa (17β-HSD) y aromatasa. La actividad enzimática de la aromatasa, 3β-HSD y 17α-hidroxilasa se detectó en el hepatopáncreas, pero de C 17 -C 20 liasa. Estos resultados sugieren que el 17β-estradiol podría ser la hormona estimuladora de la vitelogénesis (VSOH), y conjuntamente con anteriores estudios in vivo e in vitro nos dirige a proponer que de hecho debería existir una función fisiológica para las hormonas esteroides en el ciclo de maduración de los crustáceos.
