Overview of Gene Research
Emp1, encoding epithelial membrane protein 1, belongs to the peripheral myelin protein 22-kDa (PMP22) gene family [2]. Its functions are diverse, with implications in cell proliferation, migration, metastasis, and tumorigenesis through various pathways like PI3K-AKT, RAS/RAF/MAPK, and PPARγ signaling [3,4,6].
In colorectal cancer, genetic ablation of EMP1high cells, marked by Emp1, prevented metastatic recurrence in a human-like mouse model of microsatellite-stable CRC. Residual EMP1+ high-relapse cells (HRCs) in mouse livers after primary CRC surgery could give rise to multiple cell types and cause metastatic disease [1].
In osteosarcoma, knockdown of Emp1 inhibited migratory and invasive abilities of OS cells, as Emp1 was upregulated in OS tissues and promoted the malignant progression through the IRX2/MMP9 axis [5].
In gliomas, silencing Emp1 inhibited cell invasion and proliferation by inhibiting the PI3K-AKT signaling pathway and regulated stemness by affecting CD44 expression [6].
In bladder cancer, loss of Emp1 promoted migration and resistance to ferroptosis via activation of PPARγ signaling [3].
In conclusion, Emp1 plays a crucial role in the progression of multiple cancers including colorectal, osteosarcoma, glioma, and bladder cancer. Gene-knockout models in mice have been instrumental in revealing these functions, highlighting its potential as a therapeutic target for preventing cancer metastasis and relapse.
