Previous studies have shown that lysine-specific demethylase 1 (LSD1) could regulate cell cycle progression through demethylation. The 3′domain of HOX transcript antisense RNA (Hotair) combined with the LSD1/CoREST/REST complex helps LSD1 target the corresponding gene. However, its role in mice's myocardial regeneration is still unclear. The heart from neonatal mice shows strong myocardial regeneration ability, but this ability disappears 7 days after birth. Our study shows that the myocardial tissue highly expresses Hotair and Lsd1 within 1 week after birth, consistent with the myocardial regeneration time window. Knockdown Lsd1 or Hotair expression by RNA interference could inhibit myocardial regeneration and cardiomyocyte proliferation. Our results suggest that Hotair-mediated demethylation of LSD1 may play an important role in myocardial regeneration in neonatal mice. [ABSTRACT FROM AUTHOR] |
