MAD2L1 supports MYC-driven liver carcinogenesis in mice and predicts poor prognosis in human hepatocarcinoma
Listed in NCBI GEO
Mitotic arrest deficient 2 like 1 (MAD2L1) is a component of the mitotic spindle assembly checkpoint implicated in cancer cell proliferation and tumorigenesis.
Description
The functional role of MAD2L1 in hepatocellular carcinoma (HCC) has not been adequately investigated, especially in vivo. In the current manuscript, we sought to address the function of MAD2L1 in hepatocarcinogenesis.
We found that MAD2L1 expression is upregulated in human HCCs, where its expression is associated with higher aggressive tumor grade, elevated proliferative activity, and poor prognosis. In human HCC cell lines, silencing of MAD2L1 led to decreased cell growth. RNAseq results demonstrated that silencing of MAD2L1 induces the expression of genes associated with cell cycle, DNA replication, and various cancer-related pathways, supporting the critical role of MAD2L1 during HCC growth and differentiation.

In a c-MYC-induced mouse HCC model, we revealed an increased expression of Mad2l1. Furthermore, CRIPSR-based gene silencing of Mad2l1 prevented c-MYC-driven mouse liver development. Altogether, our study indicates that MAD2L1 plays a critical role in hepatocarcinogenesis, and MAD2L1 suppression might be a promising therapeutic approach for treating human HCC.
