PAX5 haploinsufficiency induce cancer cell dormancy in Raji cells

Abstract

PAX5 mutations have important role in leukemogenesis and leukemia relapse, cancer cell dormancy participates in cancer relapse, but there was no report about PAX5 mutation inducing cancer cell dormancy. we constructed the PAX5 deletion Raji cell lines using gene editing technology, evaluated dormancy biological characteristics of cell lines. Our results showed PAX5 haploinsufficiency restrained the proliferation of Raji cells, induced G0/G1 arrest of Raji cells, reduced chemotherapy sensitivity. The tumor formation rate reduced in PAX5 mutation Raji cells. Our results showed PAX5 insufficiency induced cancer cell dormancy in Raji cell.

Keywords: Cancer cell dormancy; Haploinsufficiency; PAX5.
