This study investigates the susceptibility of African spiny mice (Acomys dimidiatus) to carcinogenesis induced by DMBA/TPA, a common two-stage chemical carcinogenesis model. The research reveals that despite their high regenerative capacity, Acomys exhibits resistance to skin carcinogenesis, showing delayed tumor formation and a distinct benign tumor profile compared to C57BL/6 mice. The study highlights the role of enhanced immune response, higher apoptosis, and inhibition of Wnt/β-catenin signaling in conferring this resistance.

EZH2, the catalytic core of the Polycomb Repressive Complex 2 (PRC2), silences gene expression through H3K27me3 modification and is emerging as a master epigenetic regulator beyond cancer. The review “EZH2 in Non-Cancerous Diseases: Expanding Horizons” by Prof. Lixiang Xue's team, published in Protein & Cell, systematically uncovers EZH2’s multifaceted roles in autoimmune, fibrotic, metabolic, and neurological diseases. The authors propose a CDE3 therapeutic model to advance targeted epigenetic therapy in chronic diseases.
