A review consolidating research in humans and model organisms indicates that the circITCH functions as a tumor suppressor in glioma by sponging miR-214 to allow expression of ubiquitin-protein ligase E3, thereby suppressing proliferation and preventing apoptosis, while also targeting the Wnt/β-catenin pathway [Mehta et al. DOI:10.1016/j.pneurobio.2020.101746]. In oesophageal squamous cell carcinoma, the circITCH is downregulated and increases ITCH expression to inhibit the Wnt/β-catenin pathway [Lee et al. DOI:10.1016/j.biopha.2018.12.052]. circITCH hsa_circ_0001141 (circITCH) was found to be lower in the hearts of cancer patients suffering from doxorubicin-induced cardiomyopathy compared to those with dilated cardiomyopathy, hypertrophic cardiomyopathy, and healthy donors, and its expression ameliorates doxorubicin-induced cardiomyocyte injury [Tian et al. DOI:10.3390/molecules26041155].
