Pu-erh tea reduces the transmission of CRD-mediated alopecia risk to offspring

Circadian rhythm disorder (CRD) is closely associated with hair regression and shedding, but whether this risk can be transmitted to the offspring is unknown. Whether Pu-erh tea, with alleviating effects of CRD-mediated syndrome, can act on the transmission of alopecia risk to offspring is also unproven. Here, we obtained CRD parental mice offspring and found that CRD-mediated alopecia risk can be transmitted to offspring, especially male offspring. Parental consumption of Pu-erh tea, especially in females or both parents, reduced the risk of CRD-mediated alopecia transmitted to offspring by inhibiting subcutaneous fat accumulation (downregulation of Rab18, fat-specific protein 27 (Fsp27), and perilipin 1 (Plin1)), reducing oxidative stress and inflammation in skin tissue (NADPH oxidase 4 (NOX4)/ nuclear factor kappa-B (NF-κB)), balancing androgen and hair growth factor release (hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF), insulin-like growth factor 1 (IGF-1)), and restoring hair follicle DNA repair function (upregulation of Ku70, 8-Oxoguanine DNA glycosylase 1 (OGG1), and Rad51). Transcriptomic analysis further clarified that the mechanism stemmed from the upregulation of gene expression in pathways such as the Wnt, Hippo, and other signaling pathways.
