Objective.
To investigate the effect of small interfering RNA targeting mechanosensitive ion channel protein Piezo1 (Piezo1-siRNA) on abnormal chondrocyte proliferation exposed to mechanical stretch.
Methods.
Construct and screen effective Piezo1-siRNA sequences and explore an appropriate method to transfect lentiviral vector into chondrocytes exposed to mechanical stretch.
Western blot and RT-PCR were used to detect the mRNA and protein expression of Piezo1, Kif18A, and β-tubulin, respectively.
Flow cytometry was used to measure the changes in the chondrocyte cycle.
The proliferation of chondrocyte was evaluated by cell counting kit-8.
Results.
According to the mRNA and protein expression of Piezo1, the effective siRNA sequence was successfully screened.
Compared with the 0 h group, mechanical stretch upregulated the expression of Piezo1, Kif18A, and β-tubulin, resulting in chondrocyte cycle arrest and eventually inhibiting chondrocyte proliferation.
Moreover, Piezo1-siRNA transfection effectively blocks this process and promotes the proliferation of chondrocyte.
Conclusion.
Piezo1-siRNA can reduce the inhibition of chondrocyte proliferation induced by mechanical stretch via downregulating the expression of Kif18A and inhibiting the depolymerization of microtubules.
Piezo1-siRNA plays a protective role in chondrocytes, which provides a potential method for the treatment of OA under abnormal mechanical stimulation.
