        Testicular Development

        We are interested in understanding the role of Mullerian inhibiting substance in the testis and elucidating the hormonal and cellular interactions that are critical for testicular development. Our research involves both clinical investigations and laboratory studies. Our basic research efforts have focused on clarifying the paracrine and endocrine regulation of Leydig cell differentiation and on identifying the effects of persistent organic pollutants (endocrine disruptors, such as dioxins) on the developing male reproductive system.

        Areas of research interest:

        • Biology and regulation of Mullerian inhibiting substance
        • Sexual differentiation and intersex disorders
        • Testicular differentiation and development (fetal and postnatal) of Leydig cells
        • The effects of environmental toxins on reproductive development
        • Gonadal toxicity of chemotherapy and radiation for childhood malignancies

        schematic MIS actions in Leydig cells

        Figure 1. Mullerian Inhibiting Substance (MIS) is a negative regulator of progenitor Leydig cell proliferation and differentation and an inhibitor of adult Leydig cell androgen biosynthesis.

        TUNEL staining testicular sections

        Figure 2. TUNEL staining of representative light micrographs of 4-µm-thick testicular sections from MIS and control-treated rats on Day 15 after EDS treatment. A) Control rat. B and C) MIS-treated rats. Most of the TUNEL-positive nuclei are located within the seminferous tubules and correspond to germ cells. Arrow: interstitial cell with TUNEL-positive nucleus. Scale bar = (A and B) 100µm and (C) 25µm. (Salva A, et al. Biology of Reproduction 2004;70:600-607)

        Rotation Projects

        Potential Rotations for Students

        1. Characterize the Leydig cell phenotype of different KO and transgenic models of specific genes relevant to reproductive development to determine the role of these genes in Leydig cell development: i.e. GPR54, androgen receptor, etc.
        2. Examine the mechanisms underlying the inhibitory effects of dioxin on Leydig cell steroidogenesis and investigate the developmental basis of this.
        3. Investigate the role of MIS in the development of Leydig cell tumors.
        4. Examine MIS signaling in Leydig cells.
