Yanqing Liu et al. used Pearson’s correlation analysis of scatter plots to reveal an inconsistent relationship between HuR protein levels and mRNA levels in colorectal cancer tissues, and pointed out that the inconsistency between HuR protein and mRNA levels indicated that some post-transcriptional gene regulation mechanisms were involved in the control of HuR expression [40]. This evidence concerns the gene ELAVL1 and colorectal cancer.
