Zmynd8-flox Mouse

Zmynd8, also known as Zinc finger MYND-type containing 8, is a transcription factor, histone H3-interacting protein, and putative chromatin reader/effector. It plays a crucial role in regulating transcription during normal cellular growth and is involved in multiple biological processes and pathways [2].

In breast cancer, Zmynd8 upregulation in breast cancer stem cells (BCSCs) reduces ROS and iron to inhibit ferroptosis, leading to BCSC expansion and tumor initiation. It does this through a two-fold post-translational regulation of NRF2 [1].

In acute myeloid leukemia (AML), Zmynd8 directly activates IRF8 in parallel with the MYC proto-oncogene, and is essential for AML proliferation in vitro and in vivo [3].

In intestinal cancer, YAP-mediated Zmynd8 expression sensitizes tumors to the inhibition of the mevalonate (MVA) pathway, and disruption of the Zmynd8-dependent MVA pathway restricts the self-renewal capacity of Lgr5+ intestinal stem cells and intestinal tumorigenesis [4].

In conclusion, Zmynd8 is involved in various biological processes and disease conditions. Its role in cancer, such as in breast, AML, and intestinal cancers, has been revealed through functional studies including in vivo models. These findings suggest that Zmynd8 could potentially be a therapeutic target, and its study helps in understanding the molecular mechanisms underlying cancer development [1,2,3,4].
