Project description:Reactive oxygen species (ROS) are implicated in tumor transformation by modulating proteins involved in differentiation, proliferation and invasion. In order to identify genes that may support melanoma progression or regression after an antioxidant system (AOS) response, we developed and characterized a human melanoma cell model with different levels of ROS by stably overexpressing the antioxidant enzyme catalase in A375 amelanotic melanoma cells, and whole genome gene expression patterns were analyzed by microarrays. We used gene expression microarrays to study the AOS global response to catalase overexpression and to identify up-regulated and down-regulated genes during progression or regression of melanoma.
Project description:Functional analysis of ABCB5 in A375 and G3361 melanoma cells, by comparing stably-transfected controls to ABCB5-shRNA-targeted cells.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
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:Functional analysis of ABCB5 in A375 and G3361 melanoma cells, by comparing stably-transfected controls to ABCB5-shRNA-targeted cells. 12 samples total. Replicates n=3 for the following 4 groups: A375 pSUPER-retro-puro-Vector vs. A375 pSUPER-retro-puro-ABCB5-KD; G3361 pSUPER-retro-puro-shCNTRL vs. G3361 pSUPER-retro-puro-ABCB5-KD.

Project description:Analysis of effect of CD10 in melanoma at gene expression level. The hypothesis tested in the present study was that CD10 promotes melanoma tumor progression. Results provide important information of the significant gene expression change between CD10-transfected and mock-transfected A375 cells, such as significantly increased genes included those related to anti-apoptosis, angiogenesis and cell proliferation. Total RNA obtained from CD10-transfected A375 melanoma cells was that from compared to mock-transfected A375 cells.
