MIAT dysregulation is associated with carcinogenesis, mainly acting as an oncogene regulating cellular growth, invasion, and metastasis. The aim of the current study is to investigate the role of MIAT in the regulation of T and chronic myeloid leukemic cell survival. To this end, MIAT was silenced using MIAT-specific siRNAs in leukemic cell lines, and functional assays were performed thereafter. This investigation also aims to investigate the effects of MIAT silencing on the expression of core genes involved in cancer. Functional studies and gene expression determination confirm that MIAT knockdown not only affects short- and long-term survival and the apoptosis of leukemic cells but also plays a pivotal role in the alteration of key genes involved in cancer, including c-MYC and HIF-1A. Our observations suggest that MIAT could act as an oncogene and it has the potential to be used not only as a reliable biomarker for leukemia, but also be employed for prognostic and therapeutic purposes.<\/jats:p>","DOI":"10.3390\/ncrna9040047","type":"journal-article","created":{"date-parts":[[2023,8,11]],"date-time":"2023-08-11T12:10:23Z","timestamp":1691755823000},"page":"47","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Investigation into the Role of Long-Non-Coding RNA MIAT in Leukemia"],"prefix":"10.3390","volume":"9","author":[{"given":"Alessia","family":"Ostini","sequence":"first","affiliation":[{"name":"School of Life Sciences, Faculty of Natural Sciences, Keele University, Newcastle-under-Lyme ST5 5BG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirna","family":"Mourtada-Maarabouni","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Faculty of Natural Sciences, Keele University, Newcastle-under-Lyme ST5 5BG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Salzberg, S.
