Moreover, MALDI-MSI of fresh-frozen Barrett’s adenocarcinoma samples revealed the prognostic role of cytochrome c oxidase subunit 7A2 (COX7A2) and transgelin-2 (TAGLN2) concerning the disease-free survival, whereas the expression of the protein ion at m/z 11,185, identified as S100 calcium binding protein A10 (S100A10), was an independent prognostic factor [87]. The gene discussed is S100A10; the disease is Barrett adenocarcinoma.
