MiR-29a-3p: a potential biomarker and therapeutic target in colorectal cancer.

Cancer is frequently caused by microRNAs, which control post-transcriptional levels of gene expression by binding to target mRNAs. MiR-29a-3p has recently been shown to play a twofold function in the majority of malignancies, including colorectal cancer (CRC), according to mounting evidence. Here, we not only briefly summarize such connection between miR-29a-3p and cancers, but aslo primarily evaluate the miR-29a-3p expression pattern, clinical applicability, and molecular mechanisms in CRC to provide a guide for future studies.

[Reversing effects of curcumin on multi-drug resistance of Bel7402/5-fu cell line].

Objective: To investigate the reversing effects of curcumin on hepatocellular carcinoma drug resistance Bel7402/5-Fu cell line.

Methods: Through the exposure to gradual increased concentrations of 5-fluorouracil (5-Fu), the cell line Bel7402 was induced to establish a multi-drug resistant sub-cell line Bel7402/5-Fu. The sensitivity to 6 chemotherapeutics of Bel7402 and Bel7402/5-Fu were detected using methyl thiazolyl tetrazolium (MTT) assay.
