Langenfeld et al. (2013), Augeri et al. (2016), Newman et al. (2018) and Huang et al. (2022) reported that inhibition of the receptors for BMP and TGF-β downregulates Id1, Id2, and Id3, thereby inhibiting tumor cell growth and inducing apoptosis in tumor cells. The gene discussed is TGFB1; the disease is neoplasm.
