non small cell lung cancer knockdown non-small cell lung cancer (NSCLC) tissues up-regulated expression Knockdown of IRAIN suppressed NSCLC cells proliferation in vitro. 26722412
breast cancer qPCR etc. breast cancer tissue down-regulated locus In breast cancer tissues, we found that IRAIN lncRNA was transcribed from an intronic promoter in an antisense diretcion as compared to the IGF1R coding mRNA. Unlike the IGF1R coding RNA, this non-coding RNA was imprinted, with monoallelic expression from the paternal allele. IRAIN was aberrantly imprinted in both tumours and peripheral blood leucocytes, exhibiting a pattern of allele-switch: the allele expressed in normal tissues was inactivated and the normally imprinted allele was expressed. 25465188 Lnc2Cancer
acute myeloid leukemia qPCR, Northern blot, in vitro knockdown, ChIP etc. blood, cell lines (K562, KG-1, KG-1a, HL60, TF1) down-regulated interaction We demonstrate that this lncRNA interacts with chromatin DNA and is involved in the formation of an intrachromosomal enhancer/promoter loop. In addition, IRAIN was downregulated both in leukemia cell lines and in blood obtained from high-risk AML patients. Activating the IGF1R gene, lead to growth advantage and tumor progression. 25092925 Lnc2Cancer
