Special Issue Information

Dear Colleagues,

Tyrosine kinase receptors (TKRs) play a pivotal role in cancer progression by driving key cellular processes such as proliferation, migration, differentiation, survival, invasion, and metastasis.

Despite the success of tyrosine kinase inhibitors (TKIs) in cancer therapy, intrinsic and acquired resistance mechanisms remain a significant challenge. This Special Issue aims to explore the latest advances in TKR signaling, resistance mechanisms, and novel therapeutic strategies, including next-generation TKIs, combination treatments, and immunotherapy approaches.

We welcome authors to submit original research and review articles covering diverse aspects of TKR biology, including the identification of predictive biomarkers, the interplay between TKRs and other signaling pathways, the emerging role of non-coding RNAs in modulating TKR function, and strategies to overcome therapeutic resistance.

Topics may include, but are not limited to:

Understanding mechanisms of how tyrosine kinase receptors (TKRs) drive cancer progression and metastasis.

Mechanisms of resistance to TK inhibitors (TKIs) and strategies to overcome them.

Crosstalk between TKRs and other signaling networks in cancer.

Emerging Therapeutic Strategies, such as novel TKIs, allosteric inhibitors, and combination therapies.

Predictive biomarkers for response to TKIs in clinical settings and personalized medicine.

How TKRs influence the tumor microenvironment and immune evasion (i.e., immunotherapy).

The role of miRNAs and lncRNAs in modulating TKR signaling in cancer.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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
Recurrent genetic and chromosomal aberrations drive multiple myeloma (MM) pathogenesis. Among these, the t(4;14) translocation leads to overexpression of fibroblast growth factor receptor 3 (FGFR3) and is associated with poor prognosis.

Recurrent genetic and chromosomal aberrations drive multiple myeloma (MM) pathogenesis. Among these, the t(4;14) translocation leads to overexpression of fibroblast growth factor receptor 3 (FGFR3) and is associated with poor prognosis. However, therapeutic approaches directly targeting FGFR3-driven myeloma progression remain limited. Here, we investigated the single-agent activity of ponatinib, a multikinase inhibitor, in MM. KMS18 and U266 myeloma cell lines were treated with ponatinib, and apoptosis induction, as well as VEGF and IL-6 secretion, was assessed. RNA sequencing of MM cells revealed pathway alterations induced by ponatinib treatment, which were subsequently validated by Western blot analysis. In vivo, mice inoculated with 5T33 myeloma cells received ponatinib, and survival was monitored. Notably, ponatinib exerted potent single-agent antimyeloma activity in an FGFR3-dependent manner by inducing apoptosis and suppressing VEGF and IL-6 secretion through inhibition of JAK/STAT, PI3K/AKT, and MAPK signaling. In vivo administration prolonged survival in myeloma-bearing mice. Collectively, our findings demonstrate the therapeutic efficacy of ponatinib in FGFR3-expressing MM beyond selective FGFR3 inhibition, suggesting that concurrent suppression of multiple signaling pathways is a critical mechanism of action. These results highlight the therapeutic potential of combined FGFR3-targeted strategies in multiple myeloma and provide a rationale for further clinical investigation. Full article
