TLDR Stat3 helps skin heal but can also cause skin diseases if overactive.
The study investigated the dual role of Stat3 in skin biology, where it supported processes like wound healing, keratinocyte migration, hair follicle growth, and UV resistance, but also contributed to skin diseases such as carcinogenesis and psoriasis when persistently activated. Experiments showed that mice lacking Stat3 did not develop skin tumors, whereas those with continuously active Stat3 developed squamous cell carcinoma more quickly. Stat3 was also found to be active in human psoriatic lesions, and its inhibition improved conditions like skin cancer and psoriasis, suggesting its potential as a therapeutic target.
