PG - 1093-7 LID - 10502 [pii] AB - OBJECTIVE: The aim of the present study is to explore the mechanism of action of several proteins, including Epstein-Barr virus (EBV), B-cell lymphoma (Bcl)-2, p53, c-Myc and retinoblastoma (Rb), in Non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Between July 2010 and July 2015, samples of 142 patients with pathologically confirmed NHL which presented at our institution were included in the observation group. In addition, samples from 55 patients with hyperplastic lymphadenitis presented during the same period were enrolled as control group. The expressions of EBV (+), p53(+), Bcl-2(+), Rb(-) and c-Myc(+) were determined and compared PATIENTS AND METHODS: Between July 2010 and July 2015, samples of 142 patients with pathologically confirmed NHL which presented at our institution were included in the observation group. In addition, samples from 55 patients with hyperplastic lymphadenitis presented during the same period were enrolled as control group. The expressions of EBV (+), p53(+), Bcl-2(+), Rb(-) and c-Myc(+) were determined and compared among different subtypes and stages of NHLs of observation group. Besides, the correlation of EBV with p53, Bcl-2, Rb and c-Myc were investigated in NHLs of observation group. RESULTS: In the observation group, the expression rates of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) were significantly higher than those, respectively, in the control group (p < 0.05). No significant correlation was observed between EBV expression and the expressions of p53, Bcl-2, Rb and c-Myc in the observation group (p > 0.05). The expression rates of p53(+) and Bcl-2(+) were significantly higher in aggressive and highly-aggressive NHLs than in indolent NHLs of the observation group (p < 0.05). The expressions of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) were significantly higher in stage III-IV NHLs than in stage I-II NHLs (p < 0.05). CONCLUSIONS: The expressions of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) are closely associated with NHL pathogenesis. Expressions of these proteins are higher in later stages of NHLs, and expressions of p53(+) and Bcl-2(+) are higher in more aggressive NHLs.
