CADM1 and non-small cell lung carcinoma: Funaki et al. showed that protein 4.1R is a CADM1 downstream binding site in non-small cell lung cancer; that CADM1 can recruit protein 4.1R to the plasma membrane, promoting anchorage-independent growth of small cell lung cancer (SCLC) cells and influencing the development of small cell lung cancer; and that co-localization of the CADM1 protein 4.1R complex at the plasma membrane correlates with the pathological stage of small cell lung cancer and reflects the malignancy of small cell lung cancer pairs [49].
