Among the members of the ncRNA family, microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) play a pivotal role in the insurgence and progression of several cancers, including leukemia. Thought to have different molecular mechanisms, both miRNAs and lncRNAs act as epigenetic factors modulating gene expression and influencing hematopoietic differentiation, proliferation and immune system function. Here, we discuss the most recent findings on the main molecular mechanisms by which miRNAs and lncRNAs are involved in the pathogenesis and progression of pediatric T acute lymphoblastic leukemia (T-ALL), pointing out their potential utility as therapeutic targets and as biomarkers for early diagnosis, risk stratification and prognosis. miRNAs are involved in the pathogenesis of T-ALL, acting both as tumor suppressors and as oncomiRs. By contrast, to the best of our knowledge, the literature highlights lncRNAs as acting only as oncogenes in this type of cancer by inhibiting apoptosis and promoting cell cycle and drug resistance. Additionally, here, we discuss how these molecules could be detected in the plasma of T-ALL patients, highlighting that lncRNAs may represent a new class of promising accurate and sensitive biomarkers in these young patients. Thus, the unveiling of the aberrant signature of circulating and intracellular levels of lncRNAs could have great clinical utility for obtaining a more accurate definition of prognosis and uncovering novel therapeutic strategies against T-ALL in children. However, further investigations are needed to better define the standard methodological procedure for their quantification and to obtain their specific targeting in T-ALL pediatric patients.<\/jats:p>","DOI":"10.3390\/genes16040420","type":"journal-article","created":{"date-parts":[[2025,4,1]],"date-time":"2025-04-01T04:21:01Z","timestamp":1743481261000},"page":"420","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Aberrant Expression of Non-Coding RNAs in Pediatric T Acute Lymphoblastic Leukemia and Their Potential Application as Biomarkers"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5239-2910","authenticated-orcid":false,"given":"Neila","family":"Luciano","sequence":"first","affiliation":[{"name":"Department of Medical, Movement and Wellbeing Sciences, University of Naples Parthenope, 80133 Naples, Italy"},{"name":"CEINGE-Biotecnologie Avanzate \u201cFranco Salvatore\u201d, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi","family":"Coppola","sequence":"additional","affiliation":[{"name":"UOS Research Laboratories and Biobank, AORN Santobono-Pausilipon, 80122 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuliana","family":"Salvatore","sequence":"additional","affiliation":[{"name":"Department of Medical, Movement and Wellbeing Sciences, University of Naples Parthenope, 80133 Naples, Italy"},{"name":"CEINGE-Biotecnologie Avanzate \u201cFranco Salvatore\u201d, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8700-8042","authenticated-orcid":false,"given":"Pasquale","family":"Primo","sequence":"additional","affiliation":[{"name":"UOS Research Laboratories and Biobank, AORN Santobono-Pausilipon, 80122 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3350-5286","authenticated-orcid":false,"given":"Rosanna","family":"Parasole","sequence":"additional","affiliation":[{"name":"UOC Clinical and Translational Research, AORN Santobono-Pausilipon, 80122 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2183-7577","authenticated-orcid":false,"given":"Peppino","family":"Mirabelli","sequence":"additional","affiliation":[{"name":"UOS Research Laboratories and Biobank, AORN Santobono-Pausilipon, 80122 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca Maria","family":"Orlandella","sequence":"additional","affiliation":[{"name":"Department of Medical, Movement and Wellbeing Sciences, University of Naples Parthenope, 80133 Naples, Italy"},{"name":"CEINGE-Biotecnologie Avanzate \u201cFranco Salvatore\u201d, 80131 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lato, M.W., Przysucha, A., Grosman, S., Zawitkowska, J., and Lejman, M.
