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:Gallbladder cancer (GBC) has few therapeutic options, being gemcitabine the first-line chemotherapeutic drug. However, this treatment shows poor clinical outcomes on patients. The acquired resistance phenomenon during of the treatment is one of the main factors that leads to insufficient therapeutic effects, and the molecular mechanisms used by tumor cells against gemcitabine are still poorly understood. First, we established a GBC cell line with acquired resistance to gemcitabine (TGBC1 GemR) from parental cell line (TGBC1). After, we used microarray hybridization in TGBC1 and TGBC1 GemR to characterize their transcriptional profile to identify differentially expressed genes and/or molecular pathways involved chemoresistant cell phenotype.

The acquired resistance phenomenon during of the treatment is one of the main factors that leads to insufficient therapeutic effects, and the molecular mechanisms carried out by tumor cells against gemcitabine are still poorly understood. First, we established a GBC cell line with acquired resistance to gemcitabine (NOZ GemR) from parental cell line (NOZ). After, we used microarray hybridization in NOZ and NOZ GemR to characterize their transcriptional profile to identify differentially expressed genes and/or molecular pathways involved chemoresistant cell phenotype.
Project description:We generated gemcitabine resistant subclones from the human pancreatic cancer cell line BxPC3 using chronic low dose exposure to gemcitabine. Three gemcitabine resistant subclones (BxGR-80C, BxGR-120C and BxGR-360C) were sequenced in addition to BxPC3 cells.
