ADAMTS6 and non-small cell lung carcinoma: The main goal of the study was to evaluate the expression of five circRNA molecules formed on the DNA template of the ADAMTS6 (hsa_circ_0004418, hsa_circ_0072676), ADAMTS9 (hsa_circ_0066444) and ADAMTS12 (hsa_circ_0006624, hsa_circ_0072119) genes in lung tissue collected from patients with NSCLC.
