Recent advances in deep sequencing technologies have revealed that,while less than 2%of the human genome is transcribed into mRNA for protein synthesis,over 80%of the genome is transcribed,leading to the production of large amounts of noncoding RNAs(ncRNAs).It has been shown that ncRNAs,especially long non-coding RNAs(lncRNAs),may play crucial regulatory roles in gene *** one of the first isolated and reported lncRNAs,H19 has gained much attention due to its essential roles in regulating many physiological and/or pathological processes including embryogenesis,development,tumorigenesis,osteogen-esis,and ***,H19 mediates diverse regulatory functions by serving as competing endogenous RNAs(CeRNAs),Igf2/H19 imprinted tandem gene,modular scaffold,cooperating with H19 antisense,and acting directly with other mRNAs or ***,we summarized the current understanding of H19 in embryogenesis and development,cancer development and progression,mesenchymal stem cell lineage-specific differentiation,and metabolic *** discussed the potential regulatory mechanisms underlying H19’s func-tions in those processes although more in-depth studies are warranted to delineate the exact molecular,cellular,epigenetic,and genomic regulatory mechanisms underlying the physiolog-ical and pathological roles of ***,these lines of investigation may lead to the development of novel therapeutics for human diseases by exploiting H19 functions.
