Presentation of the Epi-CAP project

A team of researchers at the Epi-CAP project has presented this project online an the title of this presentation is "Chromatin Accessibility Profiling of insulin-producing cells derived from pancreatic alpha-cells using Epi CRISPR targeted DNA methylation - Epi-CAP".

Epi-CAP project, funded by Science Fund of the Republic of Serbia (Serbian Science and Diaspora Collaboration Program: Knowledge Exchange Vouchers), represents a continuation of previous research done within the Department of Molecular Biology, IBISS in which Epi-CRISPR constructs was used for targeted DNA methylation. By targeting defined promoter sequence of the homeobox Arx gene in alpha-cells, trans-differentiation of mouse pancreatic alpha- to insulin-producing cells (Epi-cells) was achieved. The next step in the research was to compare chromatin landscapes of control alpha- and beta-cells and Epi-cells by using ATAC-seq methodology in order to further enhance understanding of the epigenetic maintenance mechanisms that define the phenotypes of the mouse pancreatic alpha-, beta- and Epi-cell. In Serbia, alpha-cells were transfected with Epi-CRISPR construct (deactivated Cas9 fused to DNMT3a3L and 4 different guided RNA for targeting Arx gene) and sorted, after which Epi-cells including negative (alpha-cells) and positive (beta-cells) controls were shipped in triplicate to the host laboratory were ATAC-seq is routinely used. Upon arrival of the Serbian counterpart to USA, the protocol for ATAC-seq was optimized for animal cells to obtain the best quality and quantity of sequencing library.

The lecturers are:

Dr. Paja Šijačić, Postdoctoral Fellow at Department of Biology, Emory University, Atlanta, USA (Project Partner - expert from diaspora)

Dr. Anja Tolić, Research Associate at Department of Molecular Biology IBISS
