It remains to be tested whether RECQ1 transcript levels correlate with the protein level, but a statistically significant correlation with DNA copy number (Pearson’s correlation R = 0.38; P = 0.003) was observed with the estimated RECQ1 DNA copy number ranging from 3.67 for lung cancer cell line NCI_H322M to 1.35 in ovarian cancer cell line SK_OV_3. The gene discussed is RECQL; the disease is lung carcinoma.
