SIRT2 and osteosarcoma: To explore the mechanism by which SIRT2 promotes the invasion and metastasis of osteosarcoma cells, we used the BioGRID database (https://thebiogrid.org/116593/table/homo-sapiens/sirt2.html) and HitPredict database (http://www.hitpredict.org/htp_int.php?Value=5142) to search for the molecules that interact with SIRT2.
