Abstract

To discuss the expression of hTrm6p/hTrm61p in bladder urothelial carcinoma tissue and its relationship with m1A level in urine, as well as the influences of hTrm6/hTrm61 on the proliferation and apoptosis of cancer cell line on urothelium. m1A levels in urine of 32 patients of bladder urothelial carcinoma and normal people were detected by HPLC/ESI-Q-TOF-MS, hTrm6p/hTrm61p expression levels in cancer tissue and para-carcinoma tissue of the same patient were detected by western blotting, and hTrm61 expressions of cancer cell line T24, 5637, and EJ of bladder urothelium and kidney cell line HEK-293 of human embryo were detected by RT-qPCR. The hTrm61 high-expression cell line is selected to detect the situation of proliferation and apoptosis by CCK-8 and flow cytometry (FCM) after knocking out hTrm61 with siRNA. m1A level in urine of carcinoma of urinary bladder is significantly higher than that of normal people, and hTrm6p/hTrm61p expression level in cancer tissue is significantly higher than that in para-carcinoma tissue and has linear correlation with m1A level in urine. The hTrm61 expression in cell line 5637 is significantly higher than that of T24, EJ, and HEK293, and apoptosis is significantly affected after hTrm61 is kno...Continue Reading

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
