Project description:The aim of this study is to discover genes regulated by miR-204. Differential gene expression in HEK-293 cells transfected with miR-204-mimic compared to HEK-293 cells transfected with control oligo (HEK-293 control) was analyzed using the Agilent Human Whole Genome 4x44K gene expression array (Agilent Technologies, Santa Clara, CA).

HEK-293 cells were transfected with either miR-204 or a control, and gene expression was analyzed using the Agilent Human Whole Genome 4x44K array. A dye-swap was performed.
Project description:Genome-wide association studies (GWAS) have identified single nucleotide polymorphisms (SNPs) associated with increased risk for colorectal cancer (CRC). A molecular understanding of the functional consequences of this genetic variation is complicated because most GWAS SNPs are located in non-coding regions. After identifying H3K27Ac peaks in HCT116 colon cancer cells that harbor SNPs associated with an increased risk for CRC, we used CRISPR/Cas9 nuclease to delete 2 CRC risk-associated H3K27Ac peaks (E7 and E24), a peak that is not associated with CRC risk (18qE) and a region that doesn?t have H3K27Ac peak (18qNE) from HCT116 cells and analyzed effects on the transcriptome and epigenome. We also deleted E7 region from HEK 293 cells and analyzed effects on the transcriptome of HEK 293. We also confirmed the physical interaction between enhancers of our interest and their putative target genes.
