hnRNP A/B proteins are ubiquitously expressed but show higher expression in neurons than in glia (Kamma et al, 1995).
It has been reported that 24nt sRNAs are more or less evenly expressed throughout the genome, while 21nt sRNAs show higher expression from some discrete genomic regions [ 15].
In addition, it has been shown that NSCLCs from never smokers express higher levels of α6β3 subunits whereas smokers show higher expression of α1, α3 and α7 subunits and a lower expression of α6β3 nAChR subunits [47].
In addition, genes located in the inverted repeat regions did not show higher expression level than those in single copy regions (Fig. 4).
A single reference gene tends to show higher expression variability due to a number of biological factors, but additional reference genes, which are differentially dependent on those factors, could cancel such effects.
The A2B2Δ cell lines show higher expression than the A2B2 cells (Figure 4C).
The A1B1Δ cell lines show higher expression that the A1B1 cells (Figure 5C).
In the rodent, the short variants show higher expression in adult brains whereas long variants dominate during embryonic stages in rat [47].
A large number of SSTF genes that have known functions in the establishment of the dorsal progenitor domains show higher expression levels in Lbx1 mutants (Table 2).
Interestingly, though ERBB2 expression level varied in different breast tumor samples, tissues having a nuclear localization of KLF6 show higher expression of ERBB2, as observed in both tissues lots (Fig. 2, right panel).
Also, cells synchronized by thymidine and/or hydroxyurea show higher expression levels of cyclins A and B1 in S and G2 phases than in mitotically selected cells progressing normally through the cell cycle [45].
