LAMB2 and gastric cancer: In our previous study, we determined the effects of human recombinant laminin (Ln) 111, Ln121, Ln211, Ln221, Ln411, Ln421, Ln511, and Ln521 on gastric cancer cells [5], and revealed that the laminin isoform, Ln511, which consists of α5, β1, and γ1 chains, had a high affinity for gastric cancer cells, promoting cellular proliferation, increasing cell cytoplasmic volume, inhibiting invadopodia formation in some cells, and promoting the adhesion of cells to plates.
