Expression levels of DNMT1, DNMT3A, and DNMT3B mRNAs in OC tumours. (a) DNMT1 and DNMT3B mRNA levels are positively correlated in HGSOC tumours. Box plots show medians and 25–75% quartiles of DNMT mRNAs levels measured by real-time RT-PCR in HGSOC primary tumours (n = 20, Sample/Patient Group 1) relative to fallopian tube epithelium. (b-d) Scatter plots and correlation coefficients between mRNA levels of DNMT1 and DNMT3B (b), DNMT1 and DNMT3A (c), or DNMT3A and DNMT3B (d) in HGSOC primary tumours (n = 20, Sample/Patient Group 1)
