-   Nkx2-5: CARP, a cardiac ankyrin repeat protein, is downstream in the Nkx2-5 homeobox gene pathway [PMID: 9043061].
-   Hypoxia and ischemia/reperfusion (I/R) injuries in neonatal rat cardiomyocytes and I/R rat hearts can induce apoptosis-related gene GADD153 overexpression, resulting in the down-regulation of CARP transcripts [PMID: 15826945, PMID: 19299913].
-   Hypertrophic agonists activated p38 and Rac1 expression in mitogen-activated protein kinase (MAPK) pathways, which transcriptionally activate CARP expression through binding the muscle-CAT (M-CAT) elements in the promoter sequence [PMID: 8466192].
-   TGF-beta/Smads signaling induces transcription of CARP gene through CAGA motif in vascular smooth muscle cells (VSMCs) indicating a role of CARP in mediation of the inhibitory effects of TGF-beta on the proliferation of VSMCs [PMID: 11139470].
-   Incubation of rat L6 myoblasts expressing the human AR ([L6.AR](http://L6.AR)) with testosterone reduced mRNA levels for Ankrd1. As a transcriptional repressor for AR, Ankrd1 is downregulated by testosterone [PMID: 23811403].
