CBLN1 and colorectal cancer: Ecker et al. investigated the lipidome of colorectal cancer tissue in three patient cohorts and identified SM 32:1↑, SM 34:1↑, SM 35:1↑, SM 36:1↓, SM 40:1↓, SM 42:2↓, SM 42:3 and Cer d18: 1/18:0↓, Cer d18:1/20:0↓, Cer d18:1/18:1↓ and Cer d18:1/24:0↑ as lipids, which together could be used to clearly discriminate tumour from non-tumour colon tissue [25].
