studies demonstrate that OptoER significantly enhances ER-specific gene transcription and protein synthesis, leading to improved cell proliferation and migration. In a proof-of-principle study using ovariectomized (OVX) mice, OptoER demonstrated considerable therapeutic potential for vaginal atrophy, with observed improvement in epithelial thickness and keratinization. These findings suggest that OptoER provides a targeted therapeutic strategy for estrogen deficiency conditions, with significant implications for treating vaginal atrophy and promoting regenerative healing in estrogen-deprived tissues.
