Special Issue Information

Dear Colleagues,

Acute myeloid leukemia (AML) is a blood cancer characterized by a block in differentiation of leukemia blast that has acquired aberrant self-renewal potential. With an estimated 5-year overall survival of less than 30%, AML is one of the deadliest cancers. Within the past few years, advanced molecular technology has allowed for a better understanding of AML biology and pathogenesis. Unfortunately, treatment strategies have not significantly changed since 1970, and therapy failure and relapses remain high. The molecular landscape of AML affects key hematopoietic signaling pathways such as apoptosis, proliferation, and differentiation. Therefore, a better understanding of AML biology and pathology will lead to investigating new therapy strategies combining targeted agents with standard chemotherapeutic agents.

Several reports have demonstrated that AML cells have deregulated autophagy. Because of the heterogeneity of the disease, the role of autophagy as a tumor suppressor or promotor in AML is still under debate. 

For this Special Issue of Biology, we invite authors to submit original research papers and reviews that cover mechanisms or potential therapy strategies in AML involving autophagy pathways. We look forward to reading your contributions.

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. Biology is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.

Autophagy, which literally means “eat yourself”, is more than just a lysosomal degradation pathway. It is a well-known regulator of cellular metabolism and a mechanism implicated in tumor initiation/progression and therapeutic resistance in many cancers. However, whether autophagy acts as a tumor suppressor or promoter is still a matter of debate. In acute myeloid leukemia (AML), it is now proven that autophagy supports cell proliferation in vitro and leukemic progression in vivo. Mitophagy, the specific degradation of mitochondria through autophagy, was recently shown to be required for leukemic stem cell functions and survival, highlighting the prominent role of this selective autophagy in leukemia initiation and progression. Moreover, autophagy in AML sustains fatty acid oxidation through lipophagy to support mitochondrial oxidative phosphorylation (OxPHOS), a hallmark of chemotherapy-resistant cells. Nevertheless, in the context of therapy, in AML, as well as in other cancers, autophagy could be either cytoprotective or cytotoxic, depending on the drugs used. This review summarizes the recent findings that mechanistically show how autophagy favors leukemic transformation of normal hematopoietic stem cells, as well as AML progression and also recapitulates its ambivalent role in resistance to chemotherapies and targeted therapies.
