They display tissue-specific expression and are constant, abundant, and highly conserved, making them perfect markers for diagnosis and prognosis. Several studies have proposed that circRNAs are also differentially produced in malignancies where they have oncogenic effects. Furthermore, circRNAs affecting microRNAs modify the expression profile of several transcription factors which play essential roles in tumors. CircRNAs within the hematopoietic compartment were identified as modulators of mechanisms able to enhance or suppress tumor progression in blood malignancies. Moreover, several circRNAs were suggested to confer resistance to the conventional drugs employed in hematopoietic cancers. In this review, we highlight the growing role and the controlling mechanisms by which circRNAs modify multiple myeloma genesis. We propose that circRNAs can be considered as potential diagnostic and prognostic markers, can induce chemoresistance, and might represent novel therapeutic targets for multiple myeloma.<\/jats:p>","DOI":"10.3390\/cancers14071700","type":"journal-article","created":{"date-parts":[[2022,3,27]],"date-time":"2022-03-27T21:27:51Z","timestamp":1648416471000},"page":"1700","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Circular RNA as a Novel Biomarker for Diagnosis and Prognosis and Potential Therapeutic Targets in Multiple Myeloma"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6156-8239","authenticated-orcid":false,"given":"Alessandro","family":"Allegra","sequence":"first","affiliation":[{"name":"Department of Human Pathology in Adulthood and Childhood \u201cGaetano Barresi\u201d, Division of Hematology, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8055-1915","authenticated-orcid":false,"given":"Nicola","family":"Cicero","sequence":"additional","affiliation":[{"name":"Department of Biomedical and Dental Sciences and Morphofunctional Imaging, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8335-5541","authenticated-orcid":false,"given":"Alessandro","family":"Tonacci","sequence":"additional","affiliation":[{"name":"Clinical Physiology Institute, National Research Council of Italy (IFC-CNR), 56124 Pisa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caterina","family":"Musolino","sequence":"additional","affiliation":[{"name":"Department of Human Pathology in Adulthood and Childhood \u201cGaetano Barresi\u201d, Division of Hematology, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastiano","family":"Gangemi","sequence":"additional","affiliation":[{"name":"Allergy and Clinical Immunology Unit, Department of Clinical and Experimental Medicine, University of Messina, 98125 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5","DOI":"10.1038\/nrc.2017.99","article-title":"Non-coding RNA networks in cancer","volume":"18","author":"Anastasiadou","year":"2018","journal-title":"Nat.
