In the heart, Myc is also engaged in a positive feedback loop with the lncRNA small nucleolar RNA host gene 1 Snhg1 (Snhg1), promoting cardiomyocytes’ proliferation and regeneration upon both myocardial infarction and ischemia/reperfusion, with reduced CMs’ apoptosis and size of the infarcted area. This evidence concerns the gene SNHG1 and myocardial infarction.
