MEG3 and neoplasm: LncRNAs have been reported to be involved in several steps of cancer development as essential regulators, oncogenes or tumour suppressors.18,19 Along these lines, we have recently shown that the lncRNA MEG3 is a regulator of autophagy in macrophages.20 Another lncRNA, psoriasis susceptibility-related RNA gene induced by stress (PRINS) has been related to proliferation and differentiation states of keratinocytes.
