A remarkable Activity of Steroid Biosynthesis in Captopril Preserved Leydig Cells of Mice Implicated Leukotriene B4 and Gonadotropin Releasing Hormones in vitro :: Science Publishing Group

In this study, investigated whether captopril inhibited steroidogenesis and components of the Leukotriene B4 pathways are involved in GnRH agonist (GnRH)-induced testis steroidogenesis in mice Leydig cells. Primary cultures of mice Leydig cells were established. Purified Leydig cells from adult albino mice were incubated with gradual various concentrations of GnRH with and without Captopril, Luteinizing hormone (LH); LTB4, steroidogenic (testosterone) activity and LTB4 concentration were measured after various time intervals and Leydig cell viability. The maneuvers of Leydig cells treated media was covered the singular and dual actions of antisteroidogenic of captopril and the reversible activity by GnRH-LTB4 as well as contribution of LTB4 in Leydig cells testosterone production endpoint. The different treatment media are Medium alone; Medium plus captopril 60 μM, 65 μM, 70 μM, 75 μM and 80 μM 100 μM; Medium plus 2.5mU/ml leukotriene B4; Medium plus 0.1 mM LH; Medium plus 0.1 μM GnRH; Medium plus 65 μM captopril plus 2.5 mU/ml leukotriene B4;Medium plus 65 μM captopril plus 0.1 mM LH; Medium plus 65 μM captopril plus 0.1 mM GnRH; Medium plus 0.1 mM GnRH plus 2.5 mU/ml leukotriene B4 and Medium plus 65 μM captopril plus 0.1 mM GnRH plus 2.5 mU/ml leukotriene B4. Basal testosterone levels were maximal at 0.1 μM GnRH concentration and superior testosterone yield in Leydig cells incubated 0.1 μM GnRH media than without GnRH media, and the activity profile LTB4 flow up. That comparable result led to highly correlated approved the contribution of LTB4 in GnRH stimulated Leydig cell steroidogenic end point. Furthermore captopril had an abolishment effect partially of testosterone yield and recovered and improved by GnRH and LTB4. The Leydig cells viability results suggest that the major effect of GnRH is probably beyond the LTB4. The entire key; GnRH induced testosterone production and upregulated LTB4 Levels at both the captopril inhibitory LTB4-testesteron Leydig cells culture media and captopril abolished LTB4 levels; it also activated endogenous LTB4, but not LH motivated testosterone pathway. Our data show that GnRH positively regulates steroidogenesis via LTB4 signaling in mice Leydig cells. LTB4 activation by GnRH may be responsible for the induction of Ca++ signaling indirect. Possibility improve the captopril steroidogenic disruption in Leydig cells via LTB4 and/or GnRH induction of endogenous LTB4, likewise the positive maintenance of Leydig cells viability matched induce testosterone synthesis. The LTB4 production, which may ultimately modulate steroidogenesis in mice Leydig cells, and promise new antidotal and preventative of captopril adverse effects.
