Increased sumo-1/2/3 levels were detected in LMP1-positive lymphoma tissues in an LMP1-dependent manner. (a,b) RNA was extracted from 42 biopsy tissues and cDNA was made. Real-time PCR was performed to quantitate gapdh, LMP1, and sumo-1 levels. RNA yields allowed sumo-2/3 levels to be tested in 17 of the 42 samples. (a) Relative LMP1, sumo-1 and sumo-2/3 levels (relative to gapdh) were determined. The detection of LMP1 RNA levels determined is tissues were LMP1-negative (LMP1-neg) and LMP1-positive (LMP1-pos). Results are shown as the mean relative sumo-1 and sumo-2/3 levels for individual samples (shapes). Horizontal lines represent man sumo-1 and sumo-2/2 levels for the collective LMP1-neg and LMP1-pos samples. (b) Of the 19 LMP1-positive tissue samples, relative sumo-1 levels were determined in all 19 samples but relative sumo-2/3 levels were determined in only 9 samples. Results are shown as the mean relative LMP1, sumo-1, and sumo-2/3 leves of samples run in duplicate. Regression analysis was performed.
