Project description:We analyzed the genome-wide chromatin states in Zscan4 positive ES cells (Em+) and Zscan4 negative ES cells (Em-) by using FACS-sorted MC1-ZE7 ES cells. H3K27 hyperacetylation and DNA demethylation were detected in heterochromatic regions of Em+ cells. These results suggested that the heterochromatin is activated in Zscan4 positive state.

Project description:By using FACS-sorted MC1-ZE7 ES cells, we analyzed the genome-wide distribution of H3K27ac and DNA methylation in Zscan4 positive ES cells (Em+) and Zscan4 negative ES cells (Em-). H3K27 hyperacetylation and DNA demethylation were detected in heterochromatic regions of Em+ cells, but not Em- cells. These results suggested that the Zscan4 state takes "open" chromatin conformation in ES cells. H3K27ac in Zscan4 positive and negative cells
Project description:This study will be looking at whether MK-3475 (an antibody that blocks negative signals to T cells) is effective (anti-tumor activity) and safe in three different patient populations. These include: 1. patients with MSI positive colon cancer, 2. patients with MSI negative colon cancer and 3. patients with other MSI positive cancers.
