在脊椎动物中,骨形态发生蛋白(BMP)在各种生物过程中发挥着重要作用。然而,BMP 在甲壳类动物中的功能仍不清楚。本研究首次在青蟹体内克隆了一个配体(BMP7)和两个受体(Sp-BMPRIB和Sp-BMPRII)。 qRT-PCR表明配体和受体在多种组织中均有表达,尤其是在卵巢中。 BMPRs mRNA的表达随着卵巢的发育而增加,而BMP7则呈相反趋势。原位杂交显示,Sp-BMPRIB和Sp-BMPRII在卵母细胞和卵泡细胞中均表达,而Sp-BMP7仅定位于卵泡细胞。 RNAi实验表明,BMPRs沉默后,Smad1和卵黄蛋白原受体的表达水平迅速下降。根据这些数据,我们假设 inS。 paramamosain、BMP7 和 BMPRs 对卵巢发育有影响,可能是通过自分泌/旁分泌方式。
In vertebrates, bone morphogenetic proteins (BMPs) play an important role in various biological processes. However, the function of BMPs in crustaceans is still unknown. In our study, a ligand (BMP7) and two receptors (Sp-BMPRIB and Sp-BMPRII) are cloned firstly in the mud crab,Scylla paramamosain. The qRT-PCR demonstrated that both ligand and receptors were expressed in various tissues, especially in ovary. The expression of BMPRs mRNA increased along the ovarian development, while BMP7 had an opposite tendency.In-situhybridization revealed that Sp-BMPRIB and Sp-BMPRII were expressed in both oocytes and follicle cells, whereas Sp-BMP7 was exclusively localized in follicle cells. RNAi experiments showed that the expression levels of Smad1 and vitellogenin receptor declined rapidly after BMPRs were silenced. Based on these data, we hypothesized that inS. paramamosain, BMP7 and BMPRs had impact on the ovarian development, presumably via the autocrine/paracrine way.
