Special Issue Information

Dear Colleagues, 

Hematopoietic malignancies are heterogeneous disorders, usually characterized by genetic mutations in the hematopoietic stem cells (HSCs). The identification of novel markers has completely transformed the diagnosis, the prognosis, and the follow-up, thus becoming critical for monitoring the minimal residual disease and relapse. We would like to focus our attention on the no genetic alteration-driven processes that may be involved in leukemogenesis. In this regard, post-translational modifications, including phosphorylation, ubiquitination, and acetylation are fascinating mechanisms by which cells monitor essential pathways including cell cycle, apoptosis, and differentiation, and play a key role, when deregulated, in several pathologies, including blood disorders. Shedding light on this topic will help to figure out several unsolved issues.

Thus, in this special issue, we invite researchers to submit original research articles or reviews describing innovative functions of the non-genomic altered mechanisms and the processes regulating them (hypoxia, ubiquitin-proteasome system (UPS), autophagy, oxidative stress) in the leukemia field. Furthermore, research studies ranging from simple model organisms to human hematological diseases will be highly considered.

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.

Hypoxia is a critical condition that governs survival, self-renewal, quiescence, metabolic shift and refractoriness to leukemic stem cell (LSC) therapy. The present study aims to investigate the hypoxia-driven regulation of the mammalian Target of the Rapamycin-2 (mTORC2) complex to unravel it as a novel potential target in chronic myeloid leukemia (CML) therapeutic strategies. After inducing hypoxia in a CML cell line model, we investigated the activities of mTORC1 and mTORC2. Surprisingly, we detected a significant activation of mTORC2 at the expense of mTORC1, accompanied by the nuclear localization of the main substrate phospho-Akt (Ser473). Moreover, the Gene Ontology analysis of CML patients’ CD34+ cells showed enrichment in the mTORC2 signature, further strengthening our data. The deregulation of mTOR complexes highlights how hypoxia could be crucial in CML development. In conclusion, we propose a mechanism by which CML cells residing under a low-oxygen tension, i.e., in the leukemia quiescent LSCs, singularly regulate the mTORC2 and its downstream effectors.
