Cardiotoxicity Associated With a Low Doses of 5-FU Promotes Morphoquantitative Changes in the Intrinsic Cardiac Nervous System.
Cardiovasc Toxicol
January 2025
Department of Morphological Sciences, State University of Maringa, Maringa, Parana, Brazil.
5-Fluorouracil (5-FU) is a chemotherapeutic that is used to treat solid tumors. However, 5-FU is associated with several side effects, including cardiotoxicity. Considering the importance of the intrinsic cardiac nervous system (ICNS) for the heart and that little is known about effects of 5-FU on this nervous system plexus, the purpose of the present study was to evaluate effects 5-FU at a low dose on the ICNS and oxidative and inflammatory effects in the heart in Wistar rats.

As one of the most commonly used chemotherapeutic agents in clinical practice, cisplatin is unable to selectively accumulate in tumor tissue due to its lack of targeting ability, leading to increased systemic toxicities. Additionally, the effectiveness of monotherapy is greatly limited. Therefore, the development of new cisplatin-based drug delivery systems is essential to improve the effectiveness of tumor treatment.

Background: Melanoma is the most aggressive and lethal skin cancer that affects thousands of people worldwide. Ruthenium complexes have shown promising results as cancer chemotherapeutics, offering several advantages over platinum drugs, such as potent efficacy, low toxicity, and less drug resistance. Additionally, anthraquinone derivatives have broad therapeutic applications, including melanoma.

December 2024
Differentiation and Cancer Group, Institute for Research and Innovation in Health (i3S) of the University of Porto, 4200-135 Porto, Portugal.
Background: Chemoresistance is a major obstacle in high-grade serous carcinoma (HGSC) treatment. Although many patients initially respond to chemotherapy, the majority of them relapse due to Carboplatin and Paclitaxel resistance. Drug repurposing has surfaced as a potentially effective strategy that works synergically with standard chemotherapy to bypass chemoresistance.

The primary method used to pharmacologically arrest cancer development and its metastasis is to disrupt the cell division process. There are a few approaches that may be used to meet this objective, mainly through inhibiting DNA replication or mitosis. Despite intensive studies on new chemotherapeutics, the biggest problem remains the side effects associated with the inhibition of cell division in non-tumoural host cells.
