PIK3C2A and breast carcinoma: Finally, to monitor motility and tissue invasiveness of PI3KC2α‐overexpressing breast cancer cells in vivo, we took advantage of zebrafish model, to trace metastasis by live imaging in embryos.[31] Hence, we injected PB (green), PB‐PI3KC2α (red) in 48‐hpf zebrafish (Figure S6b, Supporting Information).
