ZNT1 Regulates the Proliferation, Migration and Invasion of HaCaT Cells Infected with HPV Through the PI3K/Akt Pathway

Abstract

Background: Condyloma acuminatum (CA), which is a highly contagious sexually transmitted illness generated by human papillomavirus (HPV) infection, is characterized by abnormal proliferation of keratinocytes resulting in verrucous lesions. Although solute carrier family 30 member 1 (ZNT1) is highly expressed in CA tissues, the function of ZNT1 in CA remains unclear. Methods: HPV transfection was performed in HaCaT to simulate the CA pathological environment. The mRNA and protein levels were monitored using RT-qPCR and immunoblotting. Cell viability was found using the MTT test. Cell invasion and migration were probed using the transwell and wound healing. Results: ZNT1 expression was up-regulated in CA tissues, and HPV transfection increased the expression of ZNT1. Overexpression of ZNT1 promoted the proliferation, migration and invasion of Human immortalized keratinocyte (HaCaT) transfected with HPV. Meanwhile, ZNT1 knockdown repressed the proliferation, migration and invasion of HaCaT that HPV transfected. Further research displayed that ZNT1 promoted the proliferation, migration and invasion of HaCaT transfected with HPV through the PI3K/Akt pathway. Conclusion: Our research confirmed that ZNT1 regulated the proliferation, migration and invasion of HaCaT transfected with HPV through the PI3K/Akt pathway, providing a new target for the effective remedy of CA.
