ctgf/hcs24 CAESAR is the name given to the cis-acting RNA element identified in the 3' untranslated region (3'UTR) of the human connective tissue growth factor (CTGF) messenger RNA.^[1] This gene is also known as hypertrophic chondrocyte specific 24 (hcs24).

The importance of the 3'UTR in repressing ctgf gene expression was initially characacterised^[1] and subsequently the minimal RNA element responsible for repression was identified^[2] This element was predicted to form a stable secondary structure, which acts as a post-transcriptional cis-acting element of structure-anchored repression (CAESAR).

The 3'UTR of the ctgf/hcs24 gene in chicken has also been shown to be involved in repression of gene expression.^[3]
