Micro-RNAs (miRNAs) control gene expression at the post-transcriptional level and are widely involved in carcinogenesis, playing a role as both oncogenes and tumor suppressors. MiRNAs act as potent therapeutic weapon in cancer, but their potential therapeutic use is limited by the off-target effect due to their nonspecific distribution in normal tissues. The encapsulation of miRNAs in nanostructured carriers allows targeted effects aimed to destroy cancer cells, without affecting healthy tissues. Due to their small size and the optimal surface/size ratio, nanoparticles (NPs) envelop, protect, and release miRNAs, representing a promising strategy in cancer treatment. In the present review, we discuss the latest advances in the field of miRNA-encapsulating NPs in cancer, focusing on colorectal cancer and its metastatic forms, one of the most common malignancies worldwide.

Cancer-associated fibroblasts (CAFs) exert multiple tumor-promoting functions and are key contributors to drug resistance. The mechanisms by which specific subsets of CAFs facilitate oxaliplatin resistance in colorectal cancer (CRC) have not been fully explored. This study found that THBS2 is positively associated with CAF activation, epithelial-mesenchymal transition (EMT), and chemoresistance at the pan-cancer level.

Background: Cutaneous melanoma is one of the most invasive and lethal skin malignant tumors. Compared to primary melanoma, metastatic melanoma (MM) presents poorer treatment outcomes and a higher mortality rate. The tumor microenvironment (TME) plays a critical role in MM progression and immunotherapy resistance.

Background: Mitosis and cytokinesis are regulated by reversible phosphorylation events controlled by kinases and phosphatases. Drosophila Polo kinase, like its human ortholog PLK1, plays several roles in this process. Multiple mechanisms contribute to regulate Polo/PLK1 activity, localization and interactions.

Gas therapy represents a promising strategy for cancer treatment, with nitric oxide (NO) therapy showing particular potential in tumor therapy. However, ensuring sufficient production of NO remains a significant challenge. Leveraging ultrasound-responsive nanoparticles to promote the release of NO is an emerging way to solve this challenge.
