Mitochondria, Metabolism and Cancer

Dear Colleagues,

Though the presence of abnormal metabolic activities in cancer tissues is well-established, it remains unclear how the cellular oncogenic states lead to the unusual metabolism and how the cancer metabolism contributes to tumorigenesis. In the traditional view based on the Warburg effect, cancer cells largely depend on glycolysis to produce energy even in the presence of oxygen. However, recent developments in cancer metabolism have established that both glycolysis and oxidative phosphorylation (OXPHOS) can be active in several aggressive cancer cells. Importantly, more and more experimental evidence upholds the critical role that actively functional mitochondria play in tumorigenesis and drug resistance. It has also been proposed that the metabolic plasticity in tumor cells might play a crucial role in cancer stemness and metastasis. Cancer mitochondria can utilize different kinds of resources, such as glucose, glutamine, and fatty acids, to fuel the electron transport chain (ETC) for OXPHOS. Moreover, the involvement of mitochondria in cell death mechanisms makes them important targets for tumor therapy.

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. Cells is an international peer-reviewed open access semimonthly 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.
