Selection of housekeeping gene out of five candidate housekeeping genes (U6, U44, U48, miRNA-425 and miRNA-16). a geNORM analysis showing M value. b, c NormFinder showing the stability of 5 genes on basis of ρ value and inter and intra group variability between putative genes. d Ct values ± SD method showing Ct value and standard deviation of all five genes. e Overall geometric mean showing U6 and U48 at position first
