LEF1-AS1 regulates smooth muscle cell proliferation and migration through the miR-544a/PTEN axis, indicating that LEF1-AS1 may be a potential therapeutic target in atherosclerosis.
This study reveals that lncRNA UCA1 act as an endogenous sponge of miR-26a and downregulates miR-26a expression levels, and thereby relieving the inhibition of its target gene PTEN and alleviates VSMCs proliferation against atherosclerosis.
The phosphatase and tensin homologue (PTEN) gene is critical to the pathological development of atherosclerosis, a major risk factor for atherosclerotic cerebral infarction (ACI).
