The regulation of LRPs by miRNAs in cancer: influencing cancer characteristics and responses to treatment.

The low-density lipoprotein receptor-related protein (LRP) family is a group of cell surface receptors that participate in a variety of biological processes, including lipid metabolism, Wnt signaling, and bone metabolism. miRNAs are small non-coding RNA molecules that regulate gene expression and play a role in many biological processes, including the occurrence and development of tumors. Accumulating evidence demonstrates that LRP members are modulated by miRNAs across multiple cancer types, influencing key oncogenic processes-including tumor cell proliferation, apoptosis suppression, extracellular matrix remodeling, cell adhesion, and angiogenesis. The LRPs, miRNAs, their upstream lncRNAs, and downstream signaling molecules often form complex signaling pathways to regulate the activity of tumor cells. However, the tissue-specific roles and mechanistic underpinnings of these pathways remain incompletely understood. When examining the emerging concept of the interaction between miRNAs and LRPs, we emphasize the significance of these complex regulatory layers in the initiation and progression of cancer. Collectively, these findings are critical for advancing our understanding of the role of the LRPs family in the occurrence and development of tumors, as well as for the development of new strategies for cancer treatment.
