CADM1 and lung cancer: Nevertheless, in contrast to the lung cancer cell lines A2C12 (without Cadm1 gene expression), only low levels of H3K4me3 and H3K27me3 were observed in A2B1 (with Cadm1 gene expression), and when detected these could only be amplified in not all nucleosomes (i.e. so far, in nuc 1 and nuc 3 (−1011 to −865 and −417 to −271 relative to ATG, respectively).
