Nondividing, Postpubertal Rat Sertoli Cells Resumed Proliferation after Transplantation1

O-13: Na+/K+-ATPase Alpha1 Isoform Mediates Ouabain-Induced Expression of Cyclin D1 and Proliferation of Rat Sertoli Cells

Background: Novel roles for the interaction of cardiotonic steroids to Na+/K+-ATPase have been established in recent years. The aim of the present study was to investigate the intracellular signaling events downstream the action of ouabain on Na+/K+-ATPase in Sertoli cell obtained from immature rats. Treatment of Sertoli cells with ouabain (1 μM) induced a rapid and transient increase in the ex...

Medication Compliance after Renal Transplantation1

Different roles of prepubertal and postpubertal germ cells and Sertoli cells in the regulation of serum inhibin B levels.

To elucidate the role of germ cells in the regulation of inhibin B secretion, serum inhibin B levels in prepubertal boys and adult men whom had a concurrent testicular biopsy showing either normal or impaired testicular function were compared. In addition, by immunohistochemistry the cellular localization of the two subunits of inhibin B (alpha and betaB) were examined in adult testicular tissu...

Should anticoagulation be resumed after intracerebral hemorrhage?

Intracerebral hemorrhage (ICH) is the most feared and the most deadly complication of oral anticoagulant therapy, eg, with warfarin (Coumadin). After such an event, clinicians wonder whether their patients should resume anticoagulant therapy. The authors review the management of anticoagulation during and after anticoagulation-associated ICH.

Relaxin and Sertoli cell proliferation.

Immature Sertoli cells proliferate and several factors affect their number, including the follicle stimulating hormone (FSH), testosterone, estradiol and several paracrine growth factors. Using a primary culture of Sertoli cells isolated from 15-day old Wistar rats we have shown that relaxin stimulates Sertoli cell proliferation through the activation of MEK/ERK1/2 and PI3K/AKT pathways. In con...
