Expression profiles in 46BR.1G1 cell line. Homo sapiens

46BR.1G1 cell line is impaired in DNA ligase 1 (LIG1) activity resulting in an increased level of endogenous single (SSBs) and double stranded DNA breaks (DSBs). 46BR.1G1 fibroblastoid cells represent a suitable model system to investigate how cells cope with low levels of chronic DNA damage, a condition frequently encountered in tumors. Transcriptional alterations in 46BR.1G1 cells were determined by RNAseq by comparison with 7A3, a cell line in which the defect was rescued by stable expression of ectopic wild-type Lig1. The identification of genes differentially expressed in 46BR.1G1 cells would contribute to the elucidation of DNA damage response (DDR) mechanisms.
