This invention belongs to the field of
biomedicine and discloses the application of HMOX1 inhibitors in the preparation of drugs for treating
senile vaginitis. This invention is the first to discover that the content of the
metabolite MESV1 (Guggulsterone) is significantly elevated in the
vaginal secretions of patients with
senile vaginitis. MESV1 induces
ferroptosis in vaginal epithelial cells by upregulating HMOX1
protein expression, thereby driving the
disease. Based on this, this invention proposes a novel
therapeutic strategy targeting HMOX1. The inhibitors include shRNAs targeting HMOX1 (such as SEQ ID NO: 1-3), which can be prepared into vaginal gels, creams, and other dosage forms. Simultaneously, MESV1 can also be used to prepare auxiliary diagnostic kits. This invention provides a novel target and precise treatment approach for non-hormonal treatment of
senile vaginitis.
