In other investigations, anti‐LM332 antibodies suppress metastases of LM332‐expressing squamous carcinoma, 40 and knockdown of genes expressing either the laminin β3 41 or γ2 42 chains of LM332 (LAMB3, LAMC2, respectively) in lung carcinoma cells decreases their metastatic potential. This evidence concerns the gene LAMB3 and squamous cell carcinoma.
