This study observed that intrauterine and early postnatal exposure to finasteride affected prostatic development in Mongolian gerbils, with significant sex-based differences, particularly higher alterations in female prostates.
February 2026 in “International Journal of Molecular Sciences” In this study, the researchers found that cholinergic signaling via M4 muscarinic receptors influences hair growth, with enhanced elongation observed upon activation with bethanechol, highlighting its potential role in hair biology using mouse models.
This study observed that stimulating the cholinergic system via muscarinic receptors in dermal papilla cells and other hair-related tissues promoted hair growth, with mechanisms involving the activation of Wnt/β-catenin signalling pathways in cell cultures and increased hair shaft elongation in mouse vibrissae treated with bethanechol.
