A possible linc to obesity

Both noncoding and evolutionarily nonconserved RNAs were long presumed to be nonfunctional but are increasingly reported to have biological roles. Here, Zhang et al. identified hundreds of putative long intergenic noncoding RNAs (lincRNAs) in human gluteal subcutaneous adipose tissue. Some of the nonconserved lincRNAs associated with active histone marks and transcription factor binding or were modulated by bariatric surgery–induced weight loss. The authors showed how one nonconserved lincRNA, linc-ADAL, helps regulate adipocyte differentiation and de novo lipogenesis by interacting with distinct nucleic and cytoplasmic factors. Further studies will be needed to show whether linc-ADAL could be a therapeutic target in obesity or other metabolic conditions.
