MEG3 and infarction: Several lncRNAs with a GC-AG intron were described to play a role in neuron development and growth like the MEG3 gene (You and You, 2019), the NEAT1 gene (Barry et al., 2017), the SOX2-OT gene, the GDNF-AS1 (GDNF antisense RNA 1) gene and the MIAT (myocardial infarction associated transcript) (Clark and Blackshaw, 2014).
