An oncoprotein CREPT functions as a co-factor in MYC-driven transformation and tumor growth.

Understanding the mechanisms behind MYC-driven oncogenic transformation could pave the way for identifying novel drug targets. This study explored the role of CREPT in MYC-induced malignancy by generating MYC-transformed mouse embryonic fibroblasts (MEFs) with conditional CREPT deletion. Our results demonstrated that the loss of CREPT significantly impaired MYC-induced colony formation and cell proliferation, indicating that CREPT is essential for the malignant transformation of MEFs.

Beyond mitochondrial transfer, cell fusion rescues metabolic dysfunction and boosts malignancy in adenoid cystic carcinoma.

Cancer cells with mitochondrial dysfunction can be rescued by cells in the tumor microenvironment. Using human adenoid cystic carcinoma cell lines and fibroblasts, we find that mitochondrial transfer occurs not only between human cells but also between human and mouse cells both in vitro and in vivo. Intriguingly, spontaneous cell fusion between cancer cells and fibroblasts could also emerge; specific chromosome loss might be essential for nucleus reorganization and the post-hybrid selection process.
