“…Ovulation is accompanied by broad-spectrum proteolysis mediated by a vast number of proteinase families, such as the matrix metalloproteinases, plasminogen activators /plasmin, and members of the disintegrin and metalloproteinase domain with thrombospondin (TSP) motif (ADAMTS) gene family (Ny et al 2002, Curry & Osteen 2003, Ohnishi et al 2005, Ben-Ami et al 2006. Experimental evidence supports a potential involvement of ADAMTS family members in follicular growth and the ovulatory process (Espey et al 2000, Richards et al 2002,Boerboom et al 2003, Madan et al 2003, Richards 2005, Brown et al 2006.…”

The molecular mechanisms of ovulation and luteinization have not been well established, partially due to lack of a comprehensive understanding of functionally significant genes up-regulated in response to an ovulatory stimulus and the signaling pathways involved. In the present study, transcripts increased in bovine preovulatory follicles following a GnRH-induced LH surge were identified using microarray technology. Increased expression of 368 and 878 genes was detected at 12 (368 genes) and 20 h (878 genes) following GnRH injection. The temporal, cell specific and prostanoid-dependent regulation of selected genes (ADAM10, DBI, CD36, MTSS1, TFG, and RABGAP1) identified from microarray studies and related genes (ADAM17 and AREG) of potential significance were also investigated. Expression of mRNA for DBI and CD36 was simultaneously up-regulated in theca and granulosa cells (GC) following the LH surge, whereas temporal regulation of ADAM10, MTSS1, TFG, and RABGAP1 was distinct in the two cell compartments and increased granulosa TFG and RABGAP1 mRNA were prostanoid dependent. AREG mRNA was increased in theca and GCs at 12 and 24 h following GnRH injection. ADAM17 mRNA was increased in theca, but reduced in GCs 24 h following GnRH injection. The increased ADAM17 and AREG mRNA were prostanoid dependent. ADAM10 and ADAM17 protein were increased specifically in the apex but not the base of preovulatory follicles and the increase in ADAM17 was prostanoid dependent. Results reveal novel information on the regulation of preovulatory gene expression and suggest a potential functional role for ADAM10 and ADAM17 proteins in the region of follicle rupture.

“…3). Sertoli and granulosa cells express enzymes that cleave proAMH, with the levels of the enzymes and/or their regulators varying during testicular (Nachtigal & Ingraham 1996, Guo et al 2007, Le Magueresse-Battistoni 2007, Uhrin et al 2007) and ovarian (Bae et al 2008) development, the seminiferous cycle (Guo et al 2007, Le Magueresse-Battistoni 2007, Uhrin et al 2007, the ovarian cycle (Bae et al 2008, Wang et al 2014, the stage of ovarian follicular development (Ohnishi et al 2005, Bae et al 2008, Antenos et al 2011) and during pregnancy (Kwok et al 2013). However, the AMH in ovine follicular fluid is predominantly proAMH with little AMH N,C (Campbell et al 2012), suggesting that AMH can be synthesised and released with little or no prior cleavage.…”

Anti-Mü llerian hormone (AMH) is a multi-faceted gonadal cytokine. It is present in all vertebrates with its original function in phylogeny being as a regulator of germ cells in both sexes, and as a prime inducer of the male phenotype. Its ancient functions appear to be broadly conserved in mammals, but with this being obscured by its overt role in triggering the regression of the Mü llerian ducts in male embryos. Sertoli and ovarian follicular cells primarily release AMH as a prohormone (proAMH), which forms a stable complex (AMH N,C ) after cleavage by subtilisin/kexin-type proprotein convertases or serine proteinases. Circulating AMH is a mixture of proAMH and AMH N,C , suggesting that proAMH is activated within the gonads and putatively by its endocrine target-cells. The gonadal expression of the cleavage enzymes is subject to complex regulation, and the preliminary data suggest that this influences the relative proportions of proAMH and AMH N,C in the circulation. AMH shares an intracellular pathway with the bone morphogenetic protein (BMP) and growth differentiation factor (GDF) ligands. AMH is male specific during the initial stage of development, and theoretically should produce male biases throughout the body by adding a male-specific amplification of BMP/GDF signalling. Consistent with this, some of the male biases in neuron number and the non-sexual behaviours of mice are dependent on AMH. After puberty, circulating levels of AMH are similar in men and women. Putatively, the function of AMH in adulthood maybe to add a gonadal influence to BMP/GDF-regulated homeostasis.

Review 250Introduction A Disintegrin-like and Metalloproteinase with Thrombospondin type-1 motif (ADAMTS) proteinases, which are released outside the cell (soluble), have very critical roles in damage and repair of extracellular matrix (ECM) processes (remodeling) (1). The ADAMTS family, which degrades ECM structural substrates, such as collagen, aggrecan and versican, has 19 family members (2). These enzymes, which are associated with a great deal of vital physiological processes in the ECM, are inhibited by tissue inhibitors of metalloproteinases (TIMPs) (3, 4). Family members of this group are divided into various subgroups according to their tasks in the ECM (Figure 1). ADAMTS1 (METH-1), which was identified for the first time in colon adenocarcinoma, is associated with inflammation (5) and shows anti-angiogenic properties with ADAMTS8 (METH-2) (6, 7). Especially in the physiology of ovulation, there is interest in these proteases. ADAMTS1 also takes important roles in the process of normal growth, fertility, and organogenesis (8). ADAMTS 2, 3, and 14, also known pro-collagen N-proteinases, have important roles in collagen synthesis in the ECM. Various connective tissue diseases are seen in ADAMTS2 deficiency in this group (9). ADAMTS1, -4, -5, -8, -9, -15, -16, and -18 degrade aggrecan, which is the one of the main components of the ECM; so, they are called as aggrecanases (1). ADAMTS1, -4, and -5 degrade brevican and versican, other structural ECM components (10). Versican helps hyaluronan, which is the basic element of the ECM, to stabilize the matrix (11). ADAMTS5 and -6, expressed specifically in the placenta, are thought to be responsible for implantation (12). ADAMTS7 and -12 degrade Cartilage oligomeric matrix protein (COMP), which is an essential glycoprotein in cartilage matrix (13). ADAMTS10 has important roles in the development of tissues of skin and lens. In ADAMTS10 mutations, autosomal recessive Weill-Marchesani syndrome is seen (14). Known as von Willebrand cleaving protease, ADAMTS13 has effects on coagulation and homeostasis. This protease degrades ultralarge VWF multimers that are localized in endothelial surfaces; so, it prevents thrombus formation (9). Thrombotic thrombocytopenic purpura (TTP), a serious problem during pregnancy, occurs in ADAMTS13 deficiency (15). Increased by follicle-stimulating hormone (FSH) and luteinizing hormone (LH), ADAMTS16 degrades a-2 macroglobulin in the ECM (16). ADAMTS17 is involved in estrogen-induced apoptosis in cancer cells (16). ADAMTS9 and -20 are known Playing a key role in the pathophysiology of many diseases, A Disintegrin-like and Metalloproteinase with Thrombospondin type-1 motif (AD-AMTS) proteinases have been attracted more attention in obstetrics and gynecology. First discovered in 1997, this zinc-dependent proteinase family has 19 members today. These enzymes, which are located in the extracellular matrix (ECM), have a lot of very important functions, like matrix formation and resorption, angiogenesis, ovulation, and coagulation.
