Project description:While the role of the paired-type homeobox transcription factor MIXL1 in early embryonic development has been previously established, very little is known about the role of MIXL1 in adult hematopoiesis. To determine what role MIXL1 plays in adult hematopoietic cells, we established an enforced expression model for MIXL1 in the cell line U937, then analyzed the changes of gene expression caused by increased expression of MIXL1 by microarray analysis.
Project description:While the role of the paired-type homeobox transcription factor MIXL1 in early ebryonic development has been previously established, very little is known about the role of MIXL1 in adult hematopoiesis. To determine what role MIXL1 plays in adult hematopoietic cells, we used an established enforced expression line for FLAG-tagged MIXL1 in U937, then isolated targetted regions of the genome by ChIP-Seq. Through this analysis, we identified new putative direct transcirptional targets for MIXL1 in AML and hematopoiesis.
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:Human induced pluripotent stem cells (hiPSC) possess the ability to differentiate into a multitude of tissue types but display heterogeneity in the propensity of differentiation into specific tissue lineages. An examination of isogenic hiPSC lines revealed variations in the endoderm propensity under directed differentiation conditions. Characterization of the transcriptome and proteome of the hiPSC lines showed that MIXL1 activity at the early differentiation stage correlated with the efficacy of generating definitive endoderm and further differentiation into endoderm derivatives. Enforced expression of MIXL1 in the endoderm-incompetent hiPSCs enhanced the propensity of endoderm differentiation, suggesting that modulation of key drivers of lineage differentiation can re-wire hiPSC to the desired lineage propensity for stem cell products.
