Mechanism: | Our study suggests that 5'tiRNA-33-CysACA-1 expression is elevated in SCM
and leads to impaired mitochondrial function in cardiomyocytes. Mechanistically,
5'tiRNA-33-CysACA-1 contributes to the development of SCM by targeting
peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α), a key
molecule for mitochondrial biogenesis, and affecting the stability of PGC-1α mRNA
and leading to a hindrance in mitochondrial biogenesis. |
