Transcriptomics sequencing reveals Qu-shi-yu-fa Decoction promotes hair cycle and keratinization by upregulating FOXN1 and TGM3 to treat androgenetic alopecia.

BACKGROUD: As a prevalent type of hair loss, androgenetic alopecia (AGA) is complex due to the interplay of multiple factors, which has led to a long-standing exploration gap in the field of drug treatment. Qu-shi-yu-fa Decoction (QSYF), a traditional prescription, has shown positive effects on AGA in clinical practice, but its exact therapeutic mechanism has not been fully revealed.

PURPOSE: This study aimed to elucidate the mechanism of QSYF in the treatment of AGA.

METHODS

Identification of active components of QSYF using UPLC-MS/MS analysis. An AGA model was established for C57bL/6 mice using dihydrotestosterone to assess the effects of QSYF. Hair growth was observed using dermoscopy. Skin tissues were examined histologically using hematoxylin and eosin (H&E) staining. RNA-seq was performed on mouse skin samples to identify biological processes and targets. Biological processes and targets obtained from RNA-seq analysis were evaluated using Western blotting, RT-PCR and immunofluorescence assays. Mice were treated with target inhibitors and observed for hair growth for reverse validation. Network pharmacology was utilized to identify the key signaling pathways through which the targets functioned, and Western blotting was utilized for validation.

RESULTS

The study identified 43 QSYF components.QSYF promoted hair regeneration and increased hair bulb diameter and skin thickness in AGA mice. Transcriptome analysis showed that hair cycle and keratinization were important biological processes in QSYF treatment of AGA, while QSYF could upregulate the expression of key targets FOXN1 and TGM3. Reverse experiments showed that Inhibition of FOXN1 and TGM3 leads to exacerbation of AGA. Network pharmacological analysis showed that QSYF regulation of hair cycle and keratinization involves activation of PI3K-AKT and MAPK signaling.

CONCLUSION

This study demonstrates for the first time that QSYF regulates the hair cycle by up-regulating the expression of FOXN1 and promotes keratinization by up-regulating the expression of TGM3, both of them together exerting therapeutic effects on AGA.
