Special Issue Information

Dear Colleagues,

Leukemia is a malignant tumor of the blood originating from immature leukocytes (lymphoid and myeloid). It is the most common form of childhood cancer (~1/3 of cases) and accounts for >44,000 new diagnoses and >22,000 deaths each year worldwide. Leukemia occurs due to the malignant transformation of pluripotent hematopoietic stem cells (i.e., it can give rise to both myeloid and lymphoid precursors). Rarely, it can also involve a more busy stem cell with limited self-renewal capabilities. In acute leukemias, these malignant cells are usually immature, poorly differentiated leukocytes (blasts), which may be lymphoblasts or myeloblasts. These blasts can undergo clonal expansion and proliferation, leading to replacement and interference with normal blood cell development and function, leading to clinical symptoms. This Special Issue provides the opportunity to describe recent original research in the field of leukemia, as well as the development or application of new platforms or insights and/or reviews in the field. We are particularly interested in genomics and next generation sequencing (NGS), study of the mutations, leukemia stem cell research, new therapies, epidemiological studies and new biomarker studies, pregnancy, case clinical and COVID-vaccination.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
5-azacytidine (AZA), a representative DNA-demethylating drug, has been widely used to treat myelodysplastic syndromes (MDS). However, it remains unclear whether AZA’s DNA demethylation of any specific gene is correlated with clinical responses to AZA.

5-azacytidine (AZA), a representative DNA-demethylating drug, has been widely used to treat myelodysplastic syndromes (MDS). However, it remains unclear whether AZA’s DNA demethylation of any specific gene is correlated with clinical responses to AZA. In this study, we investigated genes that could contribute to the development of evidence-based epigenetic therapeutics with AZA. A DNA microarray identified that AZA specifically upregulated the expression of 438 genes in AZA-sensitive MDS-L cells but not in AZA-resistant counterpart MDS-L/CDA cells. Of these 438 genes, the ALOX12 gene was hypermethylated in MDS-L cells but not in MDS-L/CDA cells. In addition, we further found that (1) the ALOX12 gene was hypermethylated in patients with MDS compared to healthy controls; (2) MDS classes with excess blasts showed a relatively lower expression of ALOX12 than other classes; (3) a lower expression of ALOX12 correlated with higher bone marrow blasts and a shorter survival in patients with MDS; and (4) an increased ALOX12 expression after AZA treatment was associated with a favorable response to AZA treatment. Taking these factors together, an enhanced expression of the ALOX12 gene may predict favorable therapeutic responses to AZA therapy in MDS. Full article
