The study investigates the use of plasma cell-free RNA (cfRNA) and machine learning to enhance the diagnosis and prognosis of female androgenetic alopecia (FAGA). Involving 65 FAGA patients and 41 controls, the research identified distinct cfRNA expression profiles, with significant findings including the downregulation of DNAJB9, which is linked to increased FAGA severity. The study also highlighted the involvement of JAK-STAT and WNTs pathways. A machine learning model demonstrated moderate predictive power with an AUC of 0.707. The research suggests cfRNA, particularly DNAJB9, as a promising biomarker and potential therapeutic target for FAGA.
