CADM1 and lung carcinoma: We performed chromatin immunoprecipitation (ChIP) firstly, to confirm the nucleosomal nature of analyzed DNA fragments during M.SssI mapping and MNase chromatin analysis, and secondly, to gain insights into the role of histone variants and modifications, which could affect nucleosome stability and positioning, in the transcriptional repression of Cadm1 in the lung cancer cells.
