Project description:The oocyte’s capacity to complete maturation, to succeed fertilization and to reach the blastocyst stage is what defines the oocyte’s competence. The oocyte acquires this competence working closely with somatic cells of the follicle. Cumulus and granulosa cells provided support for the oocyte’s development and conversely the oocyte influence follicular cell growth and differentiation. Existing studies support the idea that follicular-stimulated hormone and luteinizing hormone play an essential role in oocyte competence acquisition through protein kinase A (PKA) and protein kinase C (PKC) signalling in granulosa cells. Therefore, human-like granulosa cells (KGN) were treated with forskolin 10 μM and phorbol 12-myristate 13-acetate 0.1 μM for 24 hours in order to process a transcriptomic analysis of differentially express genes between treatment. Over 2000 genes were founded to be differentially express at cut-off fold change of 1.5 and a p-value of 0.05. Five major upstreams, EGF, TGFB1, VEGF, FGF2 and HGF were founded to play an important role in competence acquisition thought PKA and PKC signalling. Differentially expressed targeted genes of both signalling pathways were classified in seven major ovarian functions such as PTGS2, IL8 and IL6 in inflammation, STAR, CYP11A1, CYP19A1 in steroidogenesis, VEGFC, VEGFA, CXCR4 in angiogenesis, AREG, EGFR, SPRY2 in differentiation, BAX, BCL2L12, CASP1 in apoptosis, CCND1, CCNB1, CCNB2 in division and MMP1, MMP9, TIMP1 in ovulation. Taken together, the results of this study suggest that PKA and PKC signalling potentiate their effects in some functions such as inflammation and apoptosis while some others are more specific to one or the other protein kinase like differentiation, ovulation and angiogenesis that are thought to be more PKC-dependent in human granulosa cells.

Project description:In the ovary, proliferation and differentiation of granulosa cells (GCs) drive the growth of follicles. This is, in part, dependent on gonadotropins. Our immunohistochemical studies provided hints of mitochondrial biogenesis and intracellular redistribution in GCs of growing follicles. A cellular model, human KGN cells (granulosa cell tumor cells, derived from growing follicles) was used to study aspects of mitochondrial dynamics. To elevate cAMP and thereby mimic gonadotropin actions, forskolin (FSK) was used, which increased KGN cell size and mitochondrial DNA within 24 h. MitoTracker experiments and ultrastructural 3D reconstruction revealed that FSK treatment induced the formation of elaborate mitochondrial networks. H89, a protein kinase A (PKA) inhibitor, reduced network formation. A proteomic analysis indicated that FSK among others elevated levels of regulators of the cytoskeleton and the steroidogenic enzyme CYP11A1, located in mitochondria, was more than 3-fold increased, implying that cAMP/PKA-associated structural changes go in parallel with the acquisition of steroidogenic competence of mitochondria in KGN cells. In summary, in situ observations showed increases in mitochondria and suggested intracellular trafficking in GCs during follicular growth and indicated that they may partially be under the control of gonadotropins/cAMP. In line with this, elevation of cAMP in KGN profoundly affected mitochondria dynamics in a PKA-dependent manner and implicated cytoskeletal changes.
