NCAM1 and lung carcinoma: Here, we analyzed the miRNA expression patterns of five different blood cell subsets, including eosinophilic and neutrophilic granulocytes (CD15+), monocytes (CD14+), B-cells (CD19+), T-cells (CD3+), and natural killer (NK) cells (CD56+) and compared the respective expression patterns between lung cancer patients and healthy controls.
