Special Issue Information

Dear Colleagues,

Colorectal cancer (CRC) remains a leading cause of cancer-related morbidity and mortality worldwide. Despite notable progress in screening, diagnostics, and therapeutics, the molecular, immunological, and clinical heterogeneity of CRC continues to present major challenges in effective disease management. This Special Issue aims to gather high-quality basic and translational research that supports the development of innovative strategies for early detection, risk stratification, and personalized treatment. We welcome original research articles and comprehensive reviews exploring the genetic, epigenetic, transcriptomic, and proteomic landscapes of CRC. Particular emphasis will be placed on host–microbiota interactions, including the role of microbial metabolites, dysbiosis, and immune modulation in colorectal tumorigenesis, progression, and therapeutic response. We also encourage studies focusing on diagnostic and prognostic biomarkers, tumor microenvironment remodeling, immune profiling, mismatch repair (MMR) deficiency, microsatellite instability (MSI), and resistance mechanisms to systemic therapies. This Special Issue provides a platform for interdisciplinary studies that integrate molecular, microbial, and clinical insights, fostering precision medicine approaches for CRC patients.

This Special Issue is supervised by Dr. Gina Gheorghe, with assistance from Dr. Vlad Alexandru Ionescu (University of Medicine and Pharmacy Carol Davila Bucharest & Clinical Emergency Hospital of Bucharest, Email: vladalexandru.ionescu92@gmail.com).

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-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.

Colorectal cancer (CRC) is among the most prevalent and deadly malignancies worldwide. Despite advancements in screening and treatment, its aggressive progression and tendency to metastasize remain major challenges. Biomarkers such as cathepsins B and D, actin isoforms, and cysteine protease inhibitors may influence tumor invasion and metastasis. However, little is known about their spatial distribution in tumor versus surrounding tissue. This study aimed to evaluate the location-dependent expression of selected biomarkers in CRC tissue to better understand their role in cancer progression. Tissue samples were obtained intraoperatively from 37 CRC patients at three locations: the tumor center, and 2 cm and 5 cm from the tumor margin. The activity and concentrations of cathepsins B and D, anti-papain activity, and actin fractions (globular [G-], filamentous [F-], and total actin [T-actin]) were measured using biochemical and spectrophotometric assays. Statistical analyses included ANOVA, MANOVA, and non-parametric tests, with significance set at p < 0.05. Cathepsin B activity was significantly elevated at the tumor center and decreased with distance from the tumor (p < 0.001). F-actin and T-actin levels followed a similar pattern, with significantly higher values near the tumor core (p < 0.05). Differences in G-actin were less pronounced. No significant spatial variation was found for cathepsin D, or anti-papain activity. The G-actin/T-actin and F-actin/G-actin ratios revealed significant shifts in actin polymerization states depending on the distance from the tumor. This study demonstrates spatial heterogeneity in the expression of key biomarkers in CRC tissues. Elevated levels of cathepsin B and altered actin dynamics in tumor regions suggest their involvement in local invasion and progression. Full article
