Project description:We used microarrays to detail gene expression changes in Hs 294T human melanoma cells after treatment with elesclomol alone, or in combination with paclitaxel, to aide in identifing the mechnism of action of elesclomol. Experiment Overall Design: Hs 294T human melanoma cells were grown in vitro. They were seeded at a low density and were left untreated, treated with the vehicle, treated with elesclomol, treated with paclitaxel, or treated in combination with both elesclomol and paclitaxel. They were incubated for 6 hours before harvesting.

The cells treated with NAC were given the NAC 30 minutes prior to additional treatments. They were incubated for 6 hours before harvesting.

Project description:Purpose:Assess the difference in gene expression of taxol-resistant TNBC cells relative to parental cells (MDA-MB-436 and HS 578t) Methods: RNA-seq was performed on paclitaxel-treated MDA-MB-436 cells that are resistant to Paclitaxel (R20A, R20B, R20C) and in control-treated (DMSO) parental MDA-MB-436 cells that are sensitive to Paclitaxel (DMSO) Results: We mapped about 20 million sequence reads per sample to the human genome (hg19) and identified identified differentially expressed genes Conclusions: Our study identified genes significantly enriched or repressed in taxol-resistant cells relative to parental cells in both TNBC models (MDA_MB-436 and HS 578T)

Project description:Acquired drug resistance represents a major challenge in chemo-therapy treatment for various types of cancers. We have found that the retinoid X receptor–selective agonist bexarotene (LGD1069, Targretin) was efficacious in treating chemo-resistant cancer cells. The goal of this microarray study was to understand the mechanism of bexarotene’s role in overcoming acquired drug resistance using human breast cancer cells MDA-MB-231 as a model system and paclitaxel as model compound. After MDA-MB-231 cells were repeatedly treated with paclitaxel for 8 cycles with each cycle including a 3-day treatment with 30 nM paclitaxel and followed by a 7-day exposure to control medium, MDA cells resistant to paclitaxel were developed and their growth was no longer inhibited by paclitaxel treatment. Those MDA cells with acquired drug resistance, when treated with paclitaxel and bexarotene in combination, could regain their sensitivity and their growth were again inhibited. Therefore, RNA samples from parental MDA-MB-231 cells, paclitaxel-resistant MDA cells treated with vehicle, paclitaxel alone or in combination with bexarotene, were used for perform global gene expression profiling with Affymetrix HG-U133A gene chips.

Keywords: Drug Treatment MDA-MB-231 cells were exposed to regimens on a 10-day cycle: a 3-day treatment with 30 nM paclitaxel and followed by a 7-day exposure to control medium. Paclitaxel resistant MDA-MB-231 cells (MDA-PR) were established within 8 cycles of such treatment (80 days). These MDA-PR cells were then treated with vehicle control, paclitaxel along, or the combination of 30 nM paclitaxel ( 3 days on and 7 days off) and 1 µM Targretin (10 days on) in a new 10-day cycle for 3 months. Thus, there are four treatment groups, parent MDA cells, MDA-PR, MDA-PR treated with paclitaxel, MDA-PR treated with paclitaxel and bexarotene, and each group had four biological replicates.
