Cervical cancer has always been the top malignant cancer among female cancers in the world. Due to its recurrence, metastasis rate, and drug resistance, the treatment results of cervical cancer have been unsatisfactory. Apigetrin is present in a variety of fruits and vegetables and has been reported to have antioxidant, free radical scavenging, anti-inflammatory, and anticancer activities. Therefore, this study focuses on the effect of apigetrin on the autophagy of cervical cancer HeLa cells based on the previous research. The results showed that apigetrin can enhance the autophagy fluorescence of light chain 3B (LC3B), and further combined with quantitative real-time PCR (qPCR) and Western blotting found that the expression of autophagy-related genes and proteins p-mTOR, Beclin1, and LC3B increased, while the expression of AMPK, ULK1, and p62 decreased. In addition, apigetrin also promoted the release of Ca2+, the PERK/eIF2α/ATF4/chop, and IRE1α pathways activate endoplasmic reticulum (ER) stress. The addition of 4PBA proved that ER stress promoted autophagy in HeLa cells. Finally, the addition of the 3-MA indicates the relationship between autophagy and apoptosis in HeLa cells. Our results indicate that apigetrin has a certain anticancer potential and can be used as a drug adjuvant and food additive for the prevention and treatment of cervical cancer. |
