چکیده

Mullerian inhibiting substance (MIS) is the gonadal hormone that causes regression of the Mullerian ducts, the anlagen of the female internal reproductive structures, during male embryogenesis. MIS is a member of the large transforming growth factor-beta (TGF beta) multigene family of glycoproteins that are involved in the regulation of growth and differentiation. The proteins in this gene family are all produced as dimeric precursors and undergo posttranslational processing for activation, requiring cleavage and dissociation to release bioactive C-terminal fragments. Similarly, the 140 kilodalton (kDa) disulfide-linked homodimer of MIS is proteolytically cleaved to generate its active C-terminal fragments. The sexually dimorphic expression of MIS in Sertoli cells of the testis and granulosa cells of the ovary is critical for normal differentiation of the internal reproductive tract structures. A number of extra-Mullerian functions such as control of germ cell maturation and gonadal morphogenesis, induction of the abdominal phase of testicular descent, suppression of lung maturation, and growth inhibition of transformed cells have also been proposed for this growth-inhibitory hormone and will be discussed. This article will summarize the current understanding of the biology and multiple functions of MIS including its activation, regulation, and mechanism of action and discuss areas of interest in ongoing research.

Regulation of gonadotropin gene expression by Mullerian inhibiting substance.

In addition to its role in causing Müllerian duct regression, Müllerian inhibiting substance (MIS) is implicated in the regulation of steroidogenesis, breast and prostate growth, and ovarian follicle recruitment, all of which are processes controlled or influenced by the hypothalamic-pituitary-gonadal axis. Whereas the direct effect of MIS on gonadal, prostate, and breast cells is under investi...

The role of Müllerian inhibiting substance in the evaluation of phenotypic female patients with mild degrees of virilization.

Müllerian inhibiting substance (MIS) is a sexually dimorphic gonadal hormone with proven efficacy in the evaluation of boys with cryptorchidism and children with intersex conditions. We examined the role of MIS determination in the evaluation of 65 phenotypic females with mild virilization. Among the 28 subjects with MIS values elevated above the normal female range, all had abnormal gonadal ti...

An update on Mullerian-inhibiting substance: its potential application against ovarian cancer.

Each year, ∼25 000 women are newly diagnosed with ovarian cancer in the USA. The vast majority (>90%) of cases are of epithelial origin. This highly lethal cancer carries a mortality rate of >50% and a high risk of recurrence after conventional, first-line chemotherapy. Müllerian-inhibiting substance (MIS) is a gonadal hormone that causes regression of the Müllerian ducts. A series of studies h...

The nuclear receptor SF-1 mediates sexually dimorphic expression of Mullerian Inhibiting Substance, in vivo.

Mullerian Inhibiting Substance (MIS) functions to promote regression of the Mullerian duct during male development. Maintaining the sexually dimorphic pattern of MIS expression is essential for proper mammalian reproductive tract development. Here, we show that the intricate spatial and temporal pattern of MIS expression is directed by a remarkably small proximal promoter of only 180 base pairs...
