TRIM24 siRNA induced cell apoptosis and reduced cell viability in human nasopharyngeal carcinoma cells.

TRIM24 siRNA induced cell apoptosis and reduced cell viability in human nasopharyngeal carcinoma cells. Mol Med Rep. 2018 May 02;: Authors: Wang P, Shen N, Liu D, Ning X, Wu D, Huang X Abstract Nasopharyngeal carcinoma (NPC) is a common cancer occurring primarily in East Asia and Africa. The high rate of recurrence and metastasis of NPC continuously endangers the health of patients. The present study aimed to identify the underlying mechanisms involved in the progression of NPC and provide experimental basis to develop a novel and efficient agent against NPC. The present study measured the expression level of tripartite motif containing 24 (TRIM24) in tumor tissues from NPC patients using reverse transcription quantitative polymerase chain reaction. Subsequently, Cell Counting kit‑8 and flow cytometry were used to detect the cell proliferation and apoptosis of NPC cell lines HONE1 and CNE1 cells where the TRIM24 gene was knocked‑down with small interfering RNA (siRNA). Further, caspase kits and western blot analysis were used to detect the expression of apoptosis and angiogenesis‑associated proteins. The present study detected a higher expression level of TRIM24 in tumor tissues and NPC cell lines and lower cell viability and higher apoptotic rate were observed when TRIM24 was silenced. Meanwhile, upregulated caspase‑3 and caspase‑9 indicated induced cell apoptosis in HONE1 and CNE1 cells following the treatment with TRIM2...
