A role for ID1 in VM formation by TNBC (MDA‐MB‐231‐LM2 cells) and PDAC (BxPC‐3 and AsPC‐1) cancer cells was supported via ID1‐targeting siRNA knockdown; and concurs with a recent study by Zhang and colleagues on hepatocellular carcinoma cells [38]. This evidence concerns the gene ID1 and hepatocellular carcinoma.
