DNA methylation-regulated miR-193a-3p dictates resistance of hepatocellular carcinoma to 5-fluorouracil via repression of SRSF2 expression.
Chemoresistance prevents effective cancer therapy and is rarely predictable prior to treatment, particularly for hepatocellular carcinoma (HCC). Following the chemoresistance profiling of eight HCC cell lines to each of nine chemotherapeutics, two cell lines (QGY-7703 as a sensitive and SMMC-7721 as a resistant cell line to 5-fluorouracil (5-FU) treatment) were systematically studied for mechan...
متن کاملmiRNA-193a-5p repression of p73 controls Cisplatin chemoresistance in primary bone tumors
Osteosarcoma and Ewing Sarcoma are the two most common types of Bone Sarcomas, principally localized at the long bones of the extremities and mainly affecting adolescents and young adults. Cisplatin is one of the current options in the therapeutic arsenal of drugs available to cure these aggressive cancers. Unfortunately, chemoresistance against this agent is still a major cause of patient rela...
متن کاملmiR-342-3p regulates MYC transcriptional activity via direct repression of E2F1 in human lung cancer.
Accumulating evidence indicates that altered miRNA expression is crucially involved in lung cancer development, though scant information is available regarding how MYC, an archetypical oncogene, is regulated by miRNAs, especially via a mechanism involving MYC cofactors. In this study, we attempted to identify miRNAs involved in regulation of MYC transcriptional activity in lung cancer. To this ...
متن کاملmiR-34a repression of SIRT1 regulates apoptosis.
MicroRNA 34a (miR-34a) is a tumor suppressor gene, but how it regulates cell proliferation is not completely understood. We now show that the microRNA miR-34a regulates silent information regulator 1 (SIRT1) expression. MiR-34a inhibits SIRT1 expression through a miR-34a-binding site within the 3' UTR of SIRT1. MiR-34 inhibition of SIRT1 leads to an increase in acetylated p53 and expression of ...
متن کاملThe miR-193a-3p regulated PSEN1 gene suppresses the multi-chemoresistance of bladder cancer.
Chemoresistance prevents the curative cancer therapy, our understanding of which remains inadequate. Among the differentially expressed genes between the chemosensitive (5637) and chemoresistant (H-bc) bladder cancer cell lines, the expression level of the PSEN1 gene (presenilin 1), a key component of the γ-secretase, is negatively correlated with chemoresistance. A small interfering RNA mediat...
