| الوصف: | BACKGROUND: Gastric cancer is one of the most lethal cancers. Aberrant expression levels of genes are frequently associated with cell immortalization and the occurrence of tumors. In this study, we aimed to investigate the role of tankyrase 1 (TANK1) in gastric adenocarcinoma and clarify the underlying mechanism. METHODS: The messenger RNA (mRNA) levels of TANK1, human telomerase reverse transcriptase (h-TERT), and telomeric repeat binding factor 1 (TRF1) in clinical specimens and SGC-7901 cells were measured via real-time quantitative polymerase chain reaction (RT-qPCR). Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and immunohistochemistry (IHC) assays were utilized to observe the cell apoptosis as well as Ki67 and h-TERT expression in tumor-bearing models. The effects of TANK1 antisense oligonucleotides (TANK1 ASODN) on viability and apoptosis of SGC 7901 cells were evaluated by cell counting kit-8 and flow cytometry analysis. RESULTS: We found that TANK1 and h-TERT were both increased in gastric adenocarcinoma, while TRF1 was decreased. Tumor-bearing models demonstrated that TANK1 ASODN appeared to be effective in inhibiting tumor growth and decreasing the expression of h-TERT. Additionally, TANK1 ASODN inhibited the viability and promoted apoptosis of SGC-7901 cells. Moreover, the mRNA levels of h-TERT and TRF1 were modulated by TANK1 ASODN. CONCLUSIONS: This study revealed that TANK1 ASODN inhibits the proliferation and induced the apoptosis of gastric adenocarcinoma cells via manipulating the expression levels of h-TERT and TRF1. |
