Project description:Enforced expression of the homeobox transcription factor HOXB4 has been shown to enhance hematopoietic stem cell (HSC) self-renewal and expansion ex vivo and in vivo. In order to investigate the largely unknown downstream targets of HOXB4 in hematopoietic progenitor cells, HOXB4 was constitutively overexpressed in the primitive hematopoietic progenitor cell line, EML. Gene expression differences were compared between KLS (c-Kit+, Lin-, Sca-1+)-EML cells that overexpressed HOXB4 (KLS-EML-HOXB4) to control KLS-EML cells that were transduced with vector alone. ChIP-chip was used to identify promoter regions bound by HOXB4.

ChIP-chip was used to identify promoter regions bound by HOXB4. We overexpressed HOXB4 in EML cells. We isolated 3 separate single cell clones as assessed by Southern Blot Analysis (3 clones for EML-HOXB4 and 3 clones for control EML-GFP cells). RNA was isolated from the KLS (c-Kit+, Lin-, Sca-1+) fraction of each single cell clone population and processed for hybridization to array chips using established lab protocols. Chip-Chip analysis of the three HOXB4 overexpressing clones was performed to identify HOXB4 bound promoters.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:We report the application of sequencing technology for high-throughput profiling of RUNX1 transcription factor occupancy in mouse EML cells. RUNX1 antibody was use for chromatin immunoprecipitation followed by high-throughput sequencing to reveal RUNX1 genome occupancy in hematopoietic stem/progenitor cells. Examination of RUNX1 transcription factor occupancy in EML cells.
