Comparison of transcriptomes of CD1c negative (CD1c−) and positive (CD1c+) dendritic cells which infiltrated into lung adenocarcinoma with those located at juxtatumor indicated that there were 2846 (Figure 1(a)) and 1313 (Figure 1(b)) genes that had more than 1.5-fold increase in expression, respectively. The gene discussed is CD1C; the disease is lung adenocarcinoma.
