چکیده

Homologous-recombination (HR)-dependent repair defective cells are hypersensitive to poly (ADP-ribose) polymerase (PARP) inhibitors. Combinations of defective HR pathway and PARP inhibitors have been an effective chemotherapeutic modality. We previously showed that knockdown of the WD40-repeat containing protein, Uaf1, causes an HR repair defect in mouse embryo fibroblast cells and therefore, increases sensitivity to PARP inhibitor, ABT-888. Similarly, here, we show that ferulic acid reduces HR repair, inhibits RAD 51 foci formation, and accumulates γ-H2AX in breast cancer cells. Moreover, ferulic acid, when combined with ABT-888, renders breast cancer cells become hypersensitive to ABT-888. Our study indicates that ferulic acid in combination with ABT-888 treatment may serve as an effective combination chemotherapeutic agent as a natural bioactive compound.

Idarubicin-bromelain combination sensitizes cancer cells to conventional chemotherapy

Objective(s): The primary cytotoxic effects of anticancer drugs like idarubicin, a chemotherapeutic agent, are not limited to neoplastic cells; they also produce similar effects in normal cells. In this study, we hypothesized that the combination of idarubicin-bromelain could make cancer cells more susceptible to cytotoxicity and genotoxicity.Material...

Up-regulation of miR-21 decreases chemotherapeutic effect of dendrosomal curcumin in breast cancer cells

Objective(s): Despite the good results of anticancer activities by curcumin, there are some hurdles that limit the use of curcumin as an anticancer agent. Many methods were examined to overcome this defect like the use of the dendrosomal curcumin (DNC). There is increasing evidence that miRNAs play important roles in biological processes. In this study, we focus on the roles of microRNA-21 in t...

PARP inhibitor ABT-888 affects response of MDA-MB-231 cells to doxorubicin treatment, targeting Snail expression

To overcome cancer cells resistance to pharmacological therapy, the development of new therapeutic approaches becomes urgent. For this purpose, the use of poly(ADP-ribose) polymerase (PARP) inhibitors in combination with other cytotoxic agents could represent an efficacious strategy. Poly(ADP-ribosyl)ation (PARylation) is a post-translational modification that plays a well characterized role in...

Rapamycin sensitizes cancer cells to growth inhibition by the PARP inhibitor olaparib

Poly (ADP-ribose) polymerase inhibitors (PARPi) have been developed and tested in a context of combining it with double-stranded (ds) DNA repair defects or inhibitors, as PARP inhibitor impairs single-stranded (ss) DNA break repair, resulting in the activation of the dsDNA break repair machinery. Rapamycin has been widely prescribed for more than a decade and recent studies have revealed that i...

Reduced PAK1 activity sensitizes FA/BRCA-proficient breast cancer cells to PARP inhibition

Cells that are deficient in homologous recombination, such as those that have mutations in any of the Fanconi Anemia (FA)/BRCA genes, are hypersensitive to inhibition of poly(ADP-ribose) polymerase (PARP). However, FA/BRCA-deficient tumors represent a small fraction of breast cancers, which might restrict the therapeutic utility of PARP inhibitor monotherapy. The gene encoding the serine-threon...
