Abstract:
Thyroid cancer (TC) is the most common malignant tumor of endocrine system and head and neck. Ononin is an isoflavone component, which exhibited great antioxidant and anti-inflammatory activities. This study was conducted to explore the functions of ononin in the TC progression. The cell counting kit-8 (CCK8) assay was applied for the cell viability determination. The cell death and apoptosis rate were analyzed by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling (TUNEL) staining and flow cytometry. The quantitative real-time PCR (qRT-PCR) and Western blot assays were performed for the relative expressions determination. Lactate dehydrogenase (LDH) release assay was used to assess cytotoxicity. Ononin treatment prominently inhibited the cell viability and induced the cell apoptosis of the TC cells. Besides, caspase 3 (CASP3) was down-regulated and CD274 was up-regulated in TC. Ononin treatment prominently decreased the CD274 levels and increased the CASP3 levels in the TC cells. Additionally, ononin treatment dramatically enhanced the LDH release of the cytotoxicity of T cells. What is more, CASP3 overexpression or CD274 knockdown promoted the role of ononin in TC cells. Ononin treatment induced the cell death of the TC cells through regulating the CASP3 and CD274 expressions.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
