Unlocking the potential: integrating phytoconstituents and nanotechnology in skin cancer therapy - A comprehensive review.

Skin carcinoma, which includes basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma, is influenced by various factors such as genetic predisposition, chemical exposures, immune system imbalances, and ultraviolet (UV) radiation. This review delves into the mechanisms behind the development of these cancers, exploring the therapeutic potential of microbial, plant derived compounds and nanoparticles in advancing skin cancer treatments. Special attention is given to the cytotoxic effects of anti-neoplastic agents from microbial sources on different cancer cell lines, particularly melanoma. Additionally, the review highlights the role of phytochemicals - such as quercetin, resveratrol, and curcumin alongside vitamins, terpenoids, and sulforaphane, in management of skin cancers through mechanisms like apoptosis induction and cell cycle regulation. Recent advancements in nanotechnology-based drug delivery systems, including NP and microemulsion formulations, are also discussed for their enhanced ability to specifically target cancer cells. The diverse roles of NPs in skin cancer therapy, especially in terms of targeted drug delivery and immune modulation, are reviewed. These innovative NPs formulations have showed improved skin penetration and tumor-specific delivery, reduced systemic toxicity and enhanced therapeutic effectiveness.
