Certainly one of the p transactivated lncRNAs, lincRNA p serves as a crucial repressor in p dependent transcriptional responses by physically associating with hnRNP K and modulating its localization . Even further research also revealed that lincRNA p functions as being a posttranscriptional inhibitor of translation by selectively binding JUNB and CTNNB mRNAs, hence repressing their translation . In recent times, lncRNAs have already been emerging being a vital layer in the regulation with the gene transcription plan. Even so, the perform of lncRNAs while in the context of a variety of physiological ailments it will be nevertheless for being understood. The DNA damage response is an important anti cancer barrier to sustain genome integrity towards intrinsic and extrinsic genotoxic stresses such as ultraviolet light , ionizing radiation , chemo and radio therapeutic agents, oncogenic insults, and reactive oxygen species. The DDR includes numerous networks connecting tumor suppressor genes to DNA restore pathways, damage tolerance processes, cell cycle checkpoints and apoptosis .
The DDR is predominantly initiated by PIK family members proteins, ATM , ATR and DNA PKcs , which management the action and localization of several downstream proteins and orchestrate a lot of occasions at transcriptional, submit transcriptional and post translational ranges . The ATM kinase is a important sensor in the DDR pathway that responds in particular to double strand DNA breaks, essentially the most extreme genomic lesions. The ATM mediated phosphorylation of Apoptosis Activator 2 downstream target proteins triggers a cascade of signals to activate cell cycle checkpoints and DNA repair . In addition to canonical DNA damage signaling pathways, epigenetic alterations, such as altered DNA methylation status, histone modification patterns, chromatin remodeling, and non coding RNA regulation are actually shown to contribute as novel layers of regulation for the complexity within the DDR signaling network . Offered the big quantity of lncRNAs in genomes, it is actually assumed that expression of lncRNAs could possibly be regulated from the DDR and produce suggestions results about the DDR.
Aberrant expression of person lncRNAs has been reported in tumors of a variety of tissue origins and current information unveiled that lncRNA transcripts can modulate gene exercise in response to DNA injury . A long non coding RNA, ANRIL was located to become involved in the repression the INKB ARF INKA locus . The INKB ARF INKA locus spans all around kilobases on human chromosome p that involves three intimately linked tumor suppressor genes that set off the anti proliferative routines Cilostazol of both RB and p. Loss with the INKB ARF INKA locus certainly is the most regular copy quantity alteration across tumors and cancer cell lines . ANRIL is transcribed in anti sense course with respect towards the main INK and ARF transcripts .
