Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

Wt1 Is Required for the Regression of Müllerian Ducts in Male Mice by Inducing Wif1 and Osx Expression

Cell Proliferation, EarlyView.
Wt1 expressed in the MD mesenchyme promotes MD regression by inducing Wif1 and Osx transcription. In male mice, mesenchyme‐specific inactivation of Wt1 results in MD retention. ABSTRACT In mammals, Müllerian ducts (MDs) are the precursors of the female reproductive tract which regress in males during embryonic development.

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.
