Special Issue Information

Dear Colleagues,

Tumors are highly complex entities composed of a plethora of cell types, which altogether comprise what we call the “tumor microenvironment” (TME). Such an ecosystem contains immune, endothelial or nerve cells, as well as fibroblasts, which dynamically interact with cancer cells both at the physical and biochemical levels. Such interactions lead to acute and chronic alterations in the phenotypic characteristics of cancer and non-cancer cells, ultimately affecting tumor progression. Of particular relevance is the effect that the TME exerts over the migratory and invasive capacities of cancer cells, regulating regional and distant tumor dissemination through metastasis formation, a key feature that determines the survival of cancer patients. Understanding the TME-related mechanisms and signaling pathways related to tumor invasion and metastatic dissemination, as well as immunosuppression and therapy resistance, will provide a more detailed view of the biology of tumor progression and an opportunity to design new therapeutic approaches, specifically tackling metastasis formation.

For this Special Issue of the International Journal of Molecular Sciences, we invite authors to submit original and review articles that provide new insights on how the TME influences tumor dissemination and metastasis. Articles covering new findings on TME-related mechanisms altering cancer motility, invasion, angiogenesis, hematogenous, or lymphatic dissemination, as well as immune evasion or therapy resistance, are welcomed.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

In this study, we investigated the role of ferroptosis in the tumor microenvironment (TME) of clear cell renal cell carcinoma (ccRCC), the leading cause of renal cancer-related death. We analyzed single-cell data from seven ccRCC cases to determine cell types most correlated with ferroptosis and performed pseudotime analysis on three myeloid subtypes. We identified 16 immune-related ferroptosis genes (IRFGs) by analyzing differentially expressed genes between cell subgroups and between high and low immune infiltration groups in the TCGA-KIRC dataset and the FerrDb V2 database. Using univariate and multivariate Cox regression, we identified two independent prognostic genes, AMN and PDK4, and constructed an IRFG score model immune-related ferroptosis genes risk score (IRFGRs) to evaluate its prognostic value in ccRCC. The IRFGRs demonstrated excellent and stable performance for predicting ccRCC patient survival in both the TCGA training set and the ArrayExpress validation set, with an AUC range of 0.690–0.754, outperforming other commonly used clinicopathological indicators. Our findings enhance the understanding of TME infiltration with ferroptosis and identify immune-mediated ferroptosis genes associated with prognosis in ccRCC. Full article
