Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Gene expression in LNCaP cells after treatment with the androgen receptor targeting drugs bicalutamide (BIC), enzalutamide (ENZ) and apalutamide (ARN) in the presence or absence of dihydrotestosterone (DHT).
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Combining different clinical agents to target multiple pathways in prostate cancer cells, including androgen receptor (AR) signaling, is potentially an effective strategy to improve outcomes for men with metastatic disease. We have previously demonstrated that sub-effective concentrations of an AR antagonist, bicalutamide, a histone deacetylase inhibitor, vorinostat (SAHA), and a hsp90 inhibitor, 17-AAG, act synergistically when combined to cause death of AR-dependent prostate cancer cells. In this study, expression profiling of human prostate cancer cells treated with bicalutamide, vorinostat (SAHA) or 17-AAG, alone or in paired combination, was employed to determine the molecular mechanisms underlying these synergistic interactions. We used microarray analysis to determine the global molecular profile contributing to the synergistic cell death in LNCaP human prostate cancer cells caused by combinations of bicalutamide, vorinostat (SAHA), or 17-AAG. LNCaP human prostate cancer cells were treated for 6 hours with drug treatments as follows: vehicle control, 5 uM bicalutamide, 1 uM vorinostat (SAHA), 40 nM 17-AAG, 5 uM bicalutamide + 40 nM 17-AAG, 40 nM 17-AAG + 1 uM vorinostat (SAHA), or 5 uM bicalutamide + 1 uM vorinostat (SAHA). Each treatment was performed in sextuplicate.
