More importantly, we revealed that the degradation of lncRNA-WFDC21P played important role in the tumorigenesis of lung carcinoma, and demonstrated that by regulating DCP2, miR-4293 can elevate the expression of WFDC21P, which is described as a STAT3 binding lncRNA and specific regulator of human dendritic cell differentiation involved in some immune processes [21, 22]. The gene discussed is WFDC21P; the disease is lung carcinoma.
