Abstract EN
Background.
Oxaliplatin (L-OHP) resistance is a major obstacle to the effective treatment of colorectal cancer.
The resistance mechanism(s) of colorectal tumors to L-OHP may be related to the regulation of ERCC1 by cancer-expressed miRNAs, but no in-depth studies on the miRNAs that affect drug resistance have been performed.
Curcumin (Cur) can reverse the drug resistance of cancer cells, but its effects on ERCC1 expression and miRNA profiles in colorectal cancer have not been studied.
Methods.
To study the regulation effect of curcumin on ERCC1 expression and its effects on miRNAs, the L-OHP-resistant colorectal cancer cell line HCT116/L-OHP was established.
MTT assays were used to evaluate cell proliferation.
Flow cytometry was used to investigate apoptotic induction.
Western blot and RT-PCR analysis were used to evaluate the expression of drug-associated ERCC1, Bcl-2, GST-π, MRP, P-gp, and survivin.
Results.
HCT116//L-OHP cell lines were successfully established.
The combination of L-OHP and curcumin could reduce L-OHP resistance in vitro.
In addition, combination therapy inhibited the expression of ERCC1, Bcl-2, GST-π, MRP, P-gp, and survivin at the mRNA and protein level.
Curcumin was found to inhibit ERCC1 through its ability to modulate miR-409-3p.
Conclusion.
Curcumin can overcome L-OHP resistance in colorectal cancer cells through its effects on miR-409-3p mediated ERCC1 expression.
