APE1 apurinic/apyrimidinic endonucleasegliomas with poor prognosis61. Our confirmation, within a cohort of distinctive tumors, that the expression of APE1 correlates with that of mature miR-221/222, and inversely with that of PTEN, reinforces the relevance of our hypothesis in human cancer. Interestingly, miR-221/222 have been lately located to be post-transcriptionally dysregulated in AML patients27, in which also the APE1-endonuclease function is impaired16. Therefore, our information highlight an unexpected new mechanism by means of which APE1 overexpression may perhaps play a central function in chemoresistance by means of post-transcriptional mechanisms involving onco-miRNAs regulation and onco-miRNAs decay; these findings might open new perspectives for cancer diagnosis and therapy. Intimate cross-talks amongst miRNA-processing machineries and nuclear things is definitely an emerging field of study in the DDR pathways, which may reveal critical elements of regulation in cancer biology624. Below genotoxic tension conditions, acetylated p53 can manage the transcription and processing of some pri-miRNAs by means of association with p68 (DDX5), an RNA helicase of the DKK-3, Human (HEK293, His) DROSHA microprocessor complex65. Given that APE1 acts as a regulator and interacting partner of p5366 and it really is capable to bind some pri-miRNAs65, we may well speculate that APE1 endoribonuclease activity is really a part of the inducible mechanisms regulating the processing of precise pri-miRNAs, throughout DDR as a result of oxidative pressure and alkylating therapy. In this context, APE1 ought to control the quality from the precursor pre-miRNAs inside the nucleus through miRNA biogenesis. Quite a few modulators happen to be reported to influence the processing of pri-miRNAs apart from p68 and p53, for instance p72/p82 (DDX17), ADAR1, hnRNP A1, KSRP, SMADs, BRCA, YAP, Lin28, mutp53, DDX1, ARS2, DR5, ER, and ER64. Notably, a recent work demonstrated that an APE1-interacting protein, i.e., YB-1, regulates the biogenesis of miR-29b-2 by blocking the recruitment from the microprocessor complex and Dicer to its precursor, and upregulates the expression levels on the host transcripts of miR-221/22267. These benefits are suggestive that our novel findings on APE1, for the greatest of our knowledge, may delineate new fascinating perspectives in miRNA biology. Remarkably, APE1 may have a general role in RNA processing, not limited to miRNAs regulation. Via RIP-seq analyses, greater than 1000 transcripts were identified to become bound by APE1; they have functional involvement in RNA processing, regulation of transcription, and DNA repair with profound relevance in cancer development. This outcome offers a definitive proof onAPE1 participation in numerous pathways by means of post-transcriptional mechanisms103. By utilizing microarray analyses on HeLa cells as a cancer cell model, we previously demon.
