Abstract
Cortex Dictamni (CD) is the dried root skin of Dictamnus dasycarpus Turcz, widely used in the field of traditional Chinese medicine. Recent adverse reactions to CD limited the clinical application in combination with other traditional Chinese medicines.
To investigate the retinitis pigmentosa (RP) effects of CD using the zebrafish model and elucidate the underlying molecular mechanism of CD-induced RP in zebrafish.
The 3-dpf zebrafish larvae were divided into the control group and the CD group. RNA sequencing was conducted, followed by qRT-PCR to validate the expression of miRNAs and mRNAs. The dual luciferase reporter assay confirmed the interaction between mmu-mir-6240-p3_2 and pde6a. HT22 cells were transfected, treated with CD, and then evaluated for migration, invasion, malondialdehyde levels, superoxide dismutase activity, and acetylcholine activity.
The results showed 6228 differentially expressed genes and 66 miRNAs differentially expressed in zebrafish exposed to CD. The person correlation coefficient results showed that mmu-mir-6240-p3_2 had the highest correlation coefficient with pde6a, indicating a negative regulatory relationship. Furthermore, the results of dual luciferase reporter gene further showed that pde6a gene was the direct target of mmu-mir-6240-p3_2. Cell experiment results showed that inhibiting mir-6240-p3_2 can upregulate pde6a expression, alleviate HT22 cell injury, and reverse the inhibition of cell migration and invasion induced by CD.
CD induces RP in zebrafish by inhibiting pde6a post-transcriptional activity via mmu-mir-6240-p3_2. These findings have important implications for understanding the potential side effects of CD and for developing safer therapeutic strategies involving traditional Chinese medicines.
