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: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:Knockdown of Sox2 in SW620 colorectal cancer cells decrease their growth rates in vitro and in vivo in xenograft models. We used microarrays to detail the global programme of gene expression in Sox2 Knockdown sw620 cells compared with mock knockdown sw620 cells
Project description:Despite the docectaxel-cisplatin-5-fluorouracil (TPF) induction chemotherapy has greatly improved the patients' survival and became the standard of care for advanced nasopharyngeal carcinoma (NPC), some patients could not benefit from this therapy. The mechanism underlying the TPF chemoresistance remains unclear. Here, we identified ATMIN as a chemoresistance gene in response to TPF therapy in NPC patients. We found that USP10 deubiquitinates and stabilizes ATMIN protein. Knockdown of ATMIN inhibits the cell proliferation and facilitates the docetaxel-sensitivity of NPC cells in vitro and in vivo. Mechanistically, RNA-seq combined with ChIP-seq analysis suggests that ATMIN is associated with the cell death signaling. ATMIN transcriptionally activates LCK to facilitate cell proliferation and docetaxel-resistance. Our findings broaden the insight into the mechanism of chemoresistance in NPC and the USP10-ATMIN-LCK axis provides potential therapeutic targets for the management of NPC.
Project description:Knockdown of Sox2 in SW620 colorectal cancer cells decrease their growth rates in vitro and in vivo in xenograft models. We used microarrays to detail the global programme of gene expression in Sox2 Knockdown sw620 cells compared with mock knockdown sw620 cells Sox2 knockdown sw620 cells and and mock knockdown sw620 cells were cultured in RPMI 1640 cell culture media for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the genes regulated by Sox2 in colorectal cell lines and end (T4) of gastrulation.
