PHF14 and leukocyte adhesion deficiency: PHF14 upregulation can also be observed in our LAD tissue cohort containing 8 cases of freshly collected LAD specimens paired with adjacent non-cancerous tissues and in a panel of LAD cell lines as compared to normal lung epithelial cells (NLECs) and an immortalized normal lung epithelial cell line Beas-2B (Fig. 7c–f).
