PRDM14 is a transcriptional regulator that plays critical roles in maintaining pluripotency and promoting oncogenesis through epigenetic mechanisms. In normal development, PRDM14 maintains embryonic stem cell identity and primordial germ cell pluripotency by ensuring genome-wide DNA hypomethylation through dual mechanisms: transcriptional repression of DNA methyltransferases (Dnmt3a/b/l) and recruitment of TET proteins for active demethylation 1. The protein coordinates with pioneer transcription factors like OCT4 to establish bivalent epigenetic states that safeguard cell fate by preventing inappropriate lineage differentiation 2. In cancer contexts, PRDM14 exhibits aberrant overexpression across multiple malignancies including breast and lung adenocarcinoma, where it acts as an oncogenic driver 34. The protein promotes cancer cell survival through transcriptional activation of key metabolic regulators like CALM2 and SLC2A1, and enhances glycolysis while reducing chemosensitivity to therapeutic agents 54. Gene amplification at chromosome 8 contributes to PRDM14 overexpression in breast cancers 3. Given its low expression in normal adult tissues but high expression in various cancers, PRDM14 represents a promising therapeutic target 6.
