The expression of RECQL5 was downregulated in osteosarcoma tissues and cells.
Decreased RECQL5 correlated with osteosarcoma Enneking surgical classification.
We constructed a stable RECQL5 overexpression cell line by CRISPR/Cas9 system.
RECQL5 overexpression inhibited proliferation of MG-63 cells.
RECQL5 overexpression promoted apoptosis of MG-63 cells.
