Abstract
Nasopharyngeal carcinoma (NPC) is one of the common malignant tumors, and its pathogenesis has not been fully clarified. This study aims to explore the impact of RNA interference on the growth and invasion of NPC cells. Asparaginase and isoaspartyl peptidase 1 (ASRGL1)-short hairpin(sh) RNA expressing lentivirus was used to investigate the effect of ASRGL1 knockdown on NPC cells (C666-1 and SUN-1). The target shASRGL1 gene was determined by mRNA and protein expression in nasopharyngeal carcinoma cells; nasopharyngeal carcinoma cell proliferation viability, migration, invasion, apoptosis, ATP levels, and oxidative stress were examined. The results found that ASRGL1 was found to be highly expressed in NPC tissues and cell lines. shASRGL1 exhibited a high gene expression knockdown efficiency, downregulated the ASRGL1 protein expression in the nasopharyngeal carcinoma cells, suppressed proliferation viability of transfected nasopharyngeal carcinoma cells, inhibited their migration and invasion and ATP levels, promoted nasopharyngeal carcinoma cell apoptosis, ROS, and ferroptosis. shASRGL1 plays a role in protecting against NPC cell growth and invasion.
