MEG8 and obesity due to melanocortin 4 receptor deficiency: Herein, we investigated the regulatory role of lncMGC in obesity and adipose dysfunction using lncMGC knockout-(KO) mice and further determined the translational potential of lncMGC-based therapeutics for obesity using GapmeR antisense oligonucleotides in wild-type and partially humanized-lncMGC mice.
