Here we assessed the stability of 15 housekeeping genes in 31 tumor and normal rectal samples to validate a reliable reference gene for rectal cancer studies. Our data show that 18S and 28S RNA are stably expressed in all samples. Moreover, when used for normalization, 18S, but not 28S, greatly reduced unspecific variations of gene expression due to RNA degradation. These results demonstrate that 18S is an appropriate reference gene for normalization of RT-qPCR data from rectal cancer samples. %G English %2 https://inserm.hal.science/inserm-00396213/document %2 https://inserm.hal.science/inserm-00396213/file/Supplementary_Tables.pdf %2 https://inserm.hal.science/inserm-00396213/file/Figures_11_21.pdf %2 https://inserm.hal.science/inserm-00396213/file/Revised_manuscript_Anal_Biochem_.pdf %L inserm-00396213 %U https://inserm.hal.science/inserm-00396213 %~ INSERM %~ UNIV-MONTP1 %~ FNCLCC %~ VALDAURELLE %~ BS %~ UNIV-MONTPELLIER %~ IRCM %~ UM1-UM2 %~ UM-2015-2021
