Special Issue Information

Dear Colleagues,

Nanoparticles (NPs) are chemical entities endowed with enhanced physical and chemical characteristics, due to their lower-than-100 nm dimensions and tunable surface properties. Thus, NPs have great success in a wide variety of fields, such as in medicinal, environmental, and energy-based research, as well as in imaging and in biochemical sensing. In the biomedical area, NP-based formulations hold great promise, being particularly suited for the delivery of biomolecules and drugs, thus allowing for the development of targeted therapies for precision medicine. When administrated, upon exposure to complex biological environments, NPs quickly form a layer of adsorbed biomolecules, called the biomolecular corona. This dynamic structure comprises lipids, sugars, nucleic acids, and, mostly, proteins. After its formation, the corona dictates the fate and function of the NPs inside the body. As such, a thorough characterization of the physical and chemical properties of NPs, as well as of the biomolecular corona they acquire in different biological contexts, appears fundamental for the design of tunable delivery systems. In this scenario, omics-based approaches appear as a powerful tool for a comprehensive understanding of NPs’ properties and potential. Thus, this Special Issue welcomes both original research and review papers devoted to the characterization of the structure and function of NPs through omics strategies.

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.

Variations in Circulating Tumor Microenvironment-Associated Proteins in Non-Muscle Invasive Bladder Cancer Induced by Mitomycin C Treatment

Mitomycin C (MMC) is a widely employed chemotherapeutic agent, particularly in non-muscle invasive bladder cancer (NMIBC), where it functions by inducing DNA cross-linking and promoting tumor cell apoptosis. However, the tumor microenvironment (TME) significantly influences the therapeutic efficacy of MMC. Among the key regulators within the TME, the complement system and the coagulation pathway play a crucial role in modulating immune responses to cancer therapies, including MMC. This article explores the interaction between platinum nanoparticles (PtNPs) with human serum (HS) of NMIBC patients (T1 and Ta subtypes) at three different points: before the chemotherapy instillation of MMC (t0) and three (t3) and six months (t6) after the treatment with MMC. This novel nanoproteomic strategy allowed the identification of a TME proteomic signature associated with the response to MMC treatment. Importantly, two proteins involved in the immune response were found to be deregulated across all patients (T1 and Ta subtypes) during MMC treatment: prothrombin (F2) downregulated and complement component C7 (C7) upregulated. By understanding how these biomarker proteins interact with MMC treatment, novel therapeutic strategies can be developed to enhance treatment outcomes and overcome resistance in NMIBC. Full article
