Expression of 752 microRNAs in 77 cases of stage I non-small cell lung cancer was examined using a locked nucleic acid microarray to quantify microRNA changes associated with recurrence of the disease after surgical resection.
MicroRNA expression in eight human non-small cell lung carcinoma xenografts grown in SCID mice was compared with the primary human tumors. Formalin-fixed and paraffin-embedded tissue specimens were used.
