April 2017 in “Journal of Investigative Dermatology” This study found that knocking out STAT5 expression in specific mouse hair follicles after tamoxifen treatment initiated uniform hair growth, highlighting STAT5's role in regulating the hair growth cycle.
October 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.

October 2009 in “Cancer research” This study found that disrupting Stat3 in keratinocyte stem cells of mice reduced skin tumor formation by approximately 80%, suggesting Stat3's role in tumor initiation survival mechanisms.

November 2000 in “Proceedings of the National Academy of Sciences of the United States of America” This study demonstrated that anagen can be induced in Stat3-disrupted mice, suggesting that both Stat3-dependent and independent pathways, possibly involving PKC, mediate hair cycle progression with required PI3K activation.

November 2024 in “EMBO Molecular Medicine” In this study, researchers found that disrupting EGFR signaling in mice led to increased inflammation and hair follicle damage but that inhibiting the JAK-STAT1 pathway could restore hair growth and skin function.
