We examined the stability of (5) common housekeeping genes during Marek’s disease virus (MDV) infection: beta actin (BACT), 18 S RNA, 28 S RNA, GAPDH, and peptidyl prolyl-isomerase B (PPIB).
Samples examined were from vaccine- and oncogenic-MDV-infected chicken embryo fibroblasts and MDV-induced lymphomas.
Stability was assessed using Bestkeeper and Normfinder algorithms.
Both Bestkeeper and Normfinder algorithms determined that 28 S RNA and PPIB were the most stably expressed during all MDV infection models and the BACT was the least stable.
Our data suggest that 28 S and PPIB should be used for normalization of qRT-PCR expression during MDV infection studies.
