    • 摘要: 本试验旨在探究褪黑素(melatonin,MT)对牦牛黄体细胞生长、抗氧化性及功能的影响。本试验以健康牦牛二代黄体细胞为研究对象,比较了不同浓度MT(0(Control组)、25、125、250、500 pg·mL^(-1))对牦牛黄体细胞生长和功能的影响。通过CCK-8法检测黄体细胞的生长情况,并采用qRT-PCR检测增殖相关基因PCNA,凋亡相关基因BCL-2、BAX、FAS,抗氧化相关基因SOD1、SOD2、GPX1和CAT以及孕酮合成相关基因HSD3β、STAR和CYP11A1 mRNA的表达水平,应用ELISA检测黄体细胞ROS和孕酮水平。结果显示,添加不同浓度的MT培养能促进细胞增殖,加速黄体细胞进入平台期。MT能促进黄体细胞增殖基因PCNA和抑凋亡基因BCL-2 mRNA的表达并抑制促凋亡基因BAX、FAS的表达。同时,MT能显著降低黄体细胞中的ROS水平并促进黄体细胞分泌孕酮,且浓度在250 pg·mL^(-1)时上述作用最明显。在此浓度作用下,黄体细胞中抗氧化相关基因SOD2、GPX1及CAT和孕酮合成相关基因STAR、CYP11A1 mRNA的表达量明显上调。与仅添加MT相比,应用MT及MT受体抑制剂Luzindole联合处理黄体细胞可显著升高黄体细胞的ROS水平并抑制SOD2、GPX1及CAT的表达,孕酮水平及STAR和CYP11A1表达量均显著下调。综上表明,MT可能通过上调PCNA、BCL-2,下调BAX、FAS mRNA表达量进而促进黄体细胞增殖。MT可能通过受体介导调控了黄体细胞的ROS和孕酮水平。本研究为MT治疗黄体异常引发的生殖疾病以及其在提高牦牛繁殖性能上的应用提供了一定的理论基础。

    • 摘要: 卵巢卵泡膜细胞瘤(ovarian thecoma,OT)属于卵巢性索间质肿瘤,仅占卵巢实性肿瘤的0.5%~1.0%[1],研究表明该肿瘤混合有卵泡膜、黄体细胞以及不同含量的成纤维细胞,并在1932年进行了首次报道[2]。该肿瘤多见良性,少数OT可有癌变,有报道其恶性率为1%~5%[3]。临床表现无特异性,术前诊断不易。磁共振成像(MRI)的多参数扫描能提供软组织分辨率,为明确病变性质提供更多信息,对卵巢病变的诊断效能较高。本研究通过12例OT的临床与MRI影像学结果分析,以加深对OT的认识。

    • 摘要: 本实验旨在研究过表达miR-665对绵羊黄体细胞类固醇激素调节基因StAR、3β-HSD表达水平以及孕酮(P4)分泌水平的影响。通过miR-665模拟物及阴性对照物与绵羊黄体细胞共转染,设置空白对照组,48h后在不同转染组中分别检测miR-665的表达水平和StAR、3β-HSD的mRNA、蛋白表达水平及P4分泌水平变化。结果表明:与空白对照组和阴性对照组相比,miR-665模拟物组中miR-665的表达量极显著升高;同时,孕酮合成关键基因StAR、3β-HSD的mRNA和蛋白表达量极显著增加,分泌水平极显著升高。综上,过表达miR-665能够促进黄体细胞内StAR、3β-HSD基因表达和P4分泌,其在绵羊黄体内分泌功能调控过程中发挥重要作用。

    • 摘要: 肝素结合性表皮生长因子(heparin-binding epithelial growth factor,HB-EGF)是表皮生长因子家族中的一员,是一种跨膜蛋白膜固定型HB-EGF(proHB-EGF).proHB-EGF在特殊的金属蛋白酶作用下可水解产生可溶性HB-EGF (sHB-EGF).proHB-EGF不仅是sHB-EGF的前体,而且本身也是生物活性分子.proHB-EGF与膜蛋白形成复合体,此复合体定位于细胞间连接区,暗示proHB-EGF可能是通过近分泌机制实现其在细胞间的信号传导功能.在一个试管模型中,proHB-EGF表达为生长抑制活性,而sHB-EGF表达为生长激活活性.这些特性指出proHB-EGF和sHB-EGF是通过不同的通路发挥作用.proHB-EGF和sHB-EGF在人体内的功能尚不明确,但他们在许多生理过程中起重要作用,HB-EGF在生殖内分泌领域的研究受到极大关注,如黄体细胞的分裂与凋亡、卵泡发育、胚胎移植等.%Heparin-binding epithelial growth factor (HB-EGF),a member of the EGF family,is synthesized as a membrane-anchored precursor (proHB-EGF).ProHB-EGF is then cleaved to yield a soluble HB-EGF (sHB-EGF) by specific metalloproteases.ProHB-EGF is not only the precursor molecule for sHB-EGF but also a biologically active molecule itself.ProHB-EGF forms a complex with membrane proteins,which is localized at the cell contact site,suggesting that proHB-EGF may function in cell-to-cell signaling by a juxtacrine mechanism.In an in vitro model,proHB-EGF showed a growth inhibitory activity while sHB-EGF a growth stimulatory activity,suggesting that proHB-EGF and sHB-EGF work in different ways.However,the in vivo functions of sHB-EGF and proHB-EGF have not been defined.Many recent studies suggested that they play an important role in various physiological processes.This review introduced the potential roles of HB-EGF in reproductive endocrine,including mitosis and apoptosis of the corpus lutein cells,follicular development and embryo transfer.

    • 摘要: 奶牛黄体合成的孕酮对于维持妊娠至关重要.机体感染后产生的抗炎活性成分干扰素α(IFN-α)对奶牛妊娠产生不利影响.文章旨在研究干扰素α对奶牛黄体细胞合成孕酮功能的影响.奶牛中期黄体经机械分离和酶消化处理后分离出黄体细胞,在体外培养条件下,添加IFN-α对黄体细胞基础孕酮和促黄体素(LH)刺激后的孕酮合成水平进行研究.结果表明,IFN-α可降低牛黄体细胞基础孕酮合成水平,还减弱LH对黄体细胞孕酮合成的刺激作用.结果显示,体内的IFN-α可通过直接作用于黄体细胞影响奶牛黄体孕酮分泌水平.

    • 摘要: To explore the discipline on species distribution and value variation of periodic corpus luteum, HE staining method was adopted to measure the volumes,sizes and total number of luteal cells.The re-sults indicated a parabolic rule of luteal cells in different estrous cycle,of which,the total number of luteal cells in the Ⅳ period were at least,while,the sizes of luteal cells in Ⅰ,Ⅱand Ⅲ period were always bigger than the same cells in Ⅳ period.The data showed a dynamic relationship between the ovary,corpus luteum and estrous cycle in the mice through amounts of static data,thus,we brought forward a new theoretical basis for the classification of luteal cells,in the meantime,facilitated the establishment of computer model of corpus luteum in three-dimensional way.%为探索发情周期黄体中细胞的形态分布及数量变化规律,采用 HE染色法对发情周期中小鼠黄体的体积大小、黄体细胞的形态分布特征、细胞大小及不同大小细胞所占比例、细胞数量以及卵巢的体积大小等变化规律进行了较系统的研究。结果表明,黄体Ⅰ期中,细胞总数较多,体积中等的黄体细胞比例较高;黄体Ⅱ期中,细胞总数最多,体积中等的黄体细胞比例较高;黄体Ⅲ期中,细胞总数较多,体积中等的黄体细胞比例较高;而黄体Ⅳ期中,细胞总数最少,体积偏小的黄体细胞数量最多。通过静态数据分析,得出小鼠卵巢、黄体发育及其与小鼠发情周期阶段之间的动态关系,并为新的黄体细胞分类体系的建立和计算机模拟构建周期性黄体的三维立体构象提供了依据。

    • 摘要: 采用体外黄体细胞培养,观察中药紫草的水溶成分——紫草多糖对hCG诱导的黄体细胞分泌孕酮影响,并探讨其可能机制.选取未成年雌性SD大鼠,分离黄体细胞,分为基础组和hCG组,分别添加不同浓度紫草多糖,放射免疫检测各组细胞内和培养液中的孕酮( Progesterone,P4)含量;将细胞悬液分为4组:空白对照组、1.50g·L-1紫草多糖组、2×104 U/L hCG组以及hCG(2×104 U/L)+紫草多糖(1.50g· L-1)组,在培养的不同时间点(0、0.5、1、2h时),分别测P4产量,观察紫草多糖对培养黄体细胞作用的起效时间和动力学变化.此外,上述4组培养0.5h后离心分离细胞和培养液,分别测得细胞内和培养液中的cAMP和cGMP含量,将细胞内和培养液中的含量之和作为总量,并计算其cAMP/cGMP比值.结果表明:1.紫草多糖呈剂量依赖性地抑制hCG刺激下黄体细胞P4的生成.2.加大剂量(>3.00g· L-1)紫草多糖亦可抑制基础P4的生成.3.1.50 g· L-1紫草多糖组从作用0.5h起,即显著抑制黄体细胞hCG刺激下的P4生成(P<0.01).4.hCG可明显增加黄体细胞cAMP含量,导致cAMP/cGMP增加.添加1.50 g· L-1紫草多糖可增加cAMP、cGMP含量,但cAMP/cGMP比值下降.结论:紫草多糖可直接作用于促性腺激素的靶细胞——黄体细胞,并抑制hCG诱导黄体细胞分泌功能,该抑制作用起效快,并可能通过cGMP介导.%The effects of the water-soluble ingredients of lithospermum-lithosperman,on progesterone secretion induced by hCG in rat luteal cells Utilizing the in vitro cultured luteal cells was studied, through the in vitro cultured luteal cells. The related mechanisms were investigated, too. The Luteal cells were isolated from immature female SD rats selected and divided into control and hCG group. Different concentrations of lithosperman were added into each group. Afterwards, the contents of both intercellular progesterone and the progesterone in culture solution were detected by radioimmunity. In order to reveal the onset time and kinetic features of lithosperman on hCG secretion,the cell suspension was divided into four groups:control group,1. 50 g ? L~' lithosperman group,2X1O4 U/L hCG group and hCG(2X104 U/D+lithosperman (1. 50 g ? L"1) group. The contents of progesterone were then examined at different cultured time points (0, 0. 5,1 or 2 h) in each group. In addition,the cells after 0. 5 h culture were centrifuged and separated from the culture solutions. The total cAMP and cGMP were obtained by summing up the contents in cells and solutions,and the cAMP/cGMP ratios was calculated. The results showed: 1. Lithosperman suppressed the hcG-induced progesterone production in luteal cells in a dose-dependent manner. 2. Lithosperman in high dose (>3. 00 g ? L"1) could inhibit the basic progesterone generation in the controlled group. 3. In the con-centration of 1. 50 g ? L ' group,lithosperman started to significantly inhibit the hCG-induced progesterone generation after 0. 5 h incubation. 4. hCG obviously increased the cAMP content in luteal cells,resulting in the elevation of cAMP/cGMP ratio. However, the net effect was that cAMP/cGMP ratio decreased although the addition of 1. 50 g ? L"1 lithosperman increased the contents of both cAMP and cGMP. Conclusions: Lithosperman could inhibit the hCG-induced hormone secretion in luteal cells, which are the targets of gonadotropins. Furthermore,the quick effect of lithosperman hints that it might be mediated by cGMP.
