Detailed molecular and epigenetic characterization of the Pig IPECJ2and Chicken SL-29 cell lines


de Vos J. et al.

The pig IPECJ2 and chicken SL-29 cell lines are of interest because of their untransformed nature and wide use in functional studies. Molecular characterization of these cell lines is important to gain insight into possible molecular aberrations. The aims of this paper are providing a molecular and epigenetic characterization of the IPEC-J2 and SL-29 cell lines and providing a cell-line reference for the FAANG community, and future biomedical research. Whole genome sequencing , gene expression, DNA methylation , chromatin accessibility and ChIP-seq of four histone marks (H3K4me1, H3K4me3, H3K27ac, H3K27me3) and an insulator (CTCF) are used to achieve these aims. Heteroploidy (aneuploidy) of various chromosomes was observed from whole genome sequencing analysis in both cell lines. Furthermore, higher gene expression for genes located on chromosomes with aneuploidy in comparison to diploid chromosomes was observed. Regulatory complexity of gene expression, DNA methylation and chromatin accessibility was investigated through an integrative approach.
