S100A11 and non-small cell lung carcinoma: Apart from the genes described above, other genes, such as SRGN, which mediates specific mast cell-related granules secretion [53], S100A11, which mediates leukocyte differentiation [54], GPX1, which protects hemoglobin in circulating systems [55], and FCER1G, which regulates IgE-mediated immune response [56] in mast cells, contribute to the identification of specific subtypes of cells in certain tissues in non-small cell lung cancers.
