Jeon G, Hwang AR, Park DY, Kim JH, Kim YH, Cho BK, Min J. miRNA profiling of B16F10 melanoma cell exosomes reveals melanin synthesis-related genes. Heliyon 2024; 10:e30474. [PMID: 38711645 PMCID: PMC11070906 DOI: 10.1016/j.heliyon.2024.e30474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 04/26/2024] [Accepted: 04/27/2024] [Indexed: 05/08/2024] Open
Abstract
This study investigates the communication between skin cells, specifically melanocytes, keratinocytes, and fibroblasts, which is crucial for the process of melanin production known as melanogenesis. We aimed to understand the role of melanocyte exosomes in regulating melanogenesis and to uncover the microRNAs influencing this process. We isolated exosomes and characterized them using advanced microscopy and protein analysis to achieve this. We conducted experiments on melanoma cells to study melanin production regulation and examined how exosomes influenced gene expression related to melanogenesis. The results revealed that melanocyte exosomes increased certain types of tyrosinases, thereby enhancing melanin production. Furthermore, we acquired the miRNA profile of exosomes and hypothesized that specific siRNAs, such as miR-21a-5p, could potentially facilitate melanin synthesis. Our findings shed light on the importance of exosomes in skin health and provide valuable insights into intercellular communication mechanisms. Understanding these processes can pave the way for innovative therapies to treat melanin-related disorders and maintain healthy skin.

Abstract
The 12th Tuscany Retreat on Cancer Research and Apoptosis was held on August 19-26, 2023. The biennial retreat aims to bring together scientists who advance research in cancer, cell death, and neurodegenerative diseases. Topics covered ranged from drug resistance in cancer to insights into novel molecular cell signaling mechanisms and targets, all related to the pathways and molecules that regulate programmed cell death and the diseases that result from the dysregulation of programmed cell death. In this meeting review, we summarize the content of the most recent retreat.
