Calcium-based nanoparticles show promise for targeted, biocompatible cancer therapy via tumor microenvironment modulation
Background
Current cancer therapies often face limitations in targeted drug delivery, leading to systemic toxicity and reduced efficacy. Many nanoparticle-based approaches struggle with biocompatibility and complex synthesis requirements. Calcium-based nanoparticles, including calcium phosphate and hydroxyapatite, present a compelling alternative due to their inherent biocompatibility, biodegradability, and ability to modulate the tumor microenvironment, addressing critical gaps in precision oncology.
Study Design
This comprehensive review synthesizes recent advancements in the field of calcium-based nanoparticles for cancer treatment. It examines various synthesis methods, including wet and dry-based techniques, and discusses strategies for precise control over particle size, morphology, and surface functionalization. The review also explores the cellular interactions of these nanoparticles, their diverse therapeutic applications, and their potential clinical prospects, drawing from a broad range of preclinical studies on various calcium-derived compounds.
Results
Calcium-based nanoparticles demonstrate significant advantages in cancer therapy, primarily through their ability to modulate the tumor microenvironment and enhance targeted drug delivery. They induce cellular apoptosis via calcium overload, a key mechanism for therapeutic efficacy. Surface modifications with targeting ligands, such as antibodies, peptides, vitamins, and aptamers, significantly improve their specificity towards cancer cells, thereby reducing off-target effects. The review highlights their versatility, encompassing applications from diagnostics to therapy, and underscores their inherent safety profile due to their biocompatible and biodegradable nature. Wet and dry synthesis methods allow for precise control over physicochemical properties, optimizing performance.
