Special Issue Information
Dear Colleagues,
Post-translational modifications (PTMs) represent a major biochemical mechanism for increasing the diversity of the proteome, allowing proteins to undergo functional changes that can be dynamically adjusted in response to both intracellular and extracellular signals. In cancer, PTMs such as phosphorylation, ubiquitination, acetylation, glycosylation, and methylation are not merely secondary modifications; rather, they influence virtually every hallmark of cancer. These and other modifications regulate key cellular functions such as cell cycle progression, apoptosis, DNA repair, immune responses, and metabolism. However, cancer cells frequently hijack PTMs, exploiting these mechanisms to promote uncontrolled growth, evade apoptosis, drive metastasis, and resist treatment.
The targeting of these aberrant PTM pathways presents a vast array of potential avenues for therapeutic intervention. One of the most well-known examples is the aberrant tyrosine kinase activity of the BCR-ABL fusion protein in chronic myeloid leukemia. Imatinib, a pioneering therapeutic agent that targets this hyperactive kinase and was specifically developed for this purpose, exemplifies how correcting PTM-driven dysregulation can result in effective cancer treatment, opening the door to a wide range of cancer treatments.
This Special Issue will collect the latest research on the pivotal roles of PTMs in the diverse stages and forms of cancer, with particular interest in mechanistic studies aimed at revealing how specific PTMs contribute to tumor initiation, progression, and metastasis. Furthermore, comprehensive reviews of current treatments targeting PTMs, which should examine the efficacy of existing therapies and highlight new therapeutic avenues, will be welcomed.
By collecting a broad spectrum of research, the aim is to provide a deeper understanding of the molecular mechanism controlled by PTMs in tumors and of how manipulating PTMs can revolutionize cancer treatment and improve patient outcomes.

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.
