Correlation of EBV Infection with Expression of TNF-α-Inducing Protein 3 Gene and A20 Protein in Hodgkin's Lmphoma / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To analyze the correlation of EBV infection with expression of TNF-α-inducing protein 3 gene and A20 protein in Hodgkin lmphoma.@*METHODS@#The clinical data and pathological specimens of 65 cases of Hodgkin's lymphoma in our hospital were analyzed retrospectively, and the tissue chips were made for the rich area of the tumor cells. The latent membrane protein 1 encoded by EBV was measured by immunohistochemical staining, and the RNA encoded by EBV was measured by in situ hybridization to analyze the infection state. The gene expression of tumor necrosis factor.α-induced protein 3 was detected by fluorescence in situ hybridization, and the expression of A20 protein encoded by EBV was detected by immunohistochemical staining. The obtained data were processed by SPSS 23.0 version statistical software.@*RESULTS@#The positive rate of latent membrane protein 1 was 26.15% (17/65), the positive rate of EBV encoded RNA was 26.15% (17/65), and the coincidence rate was 100.00%. In 65 patients, A20 protein expression was lost in 18 cases (27.69%), and 14 cases (21.54%) showed homozygous or heterozygous deletion of tumor necrosis factorα protein 3 gene. Only 1 case showed A20 loss combined with homozygous deletion of TNFα inducible protein 3. Correlation analysis showed that EBV infection did not significantly relate with expression loss of A20 protein and the gene deletion of TNF-α inducing protein 3 (P>0.05).@*CONCLUSION@#The expression loss of A20 protein and gene detection of TNFα inducing protein 3 are found in both EBV negative and positive patients with Hodgkin's lymphoma, however the results of immunohistochemical staining and fluorescence in situ hybridization are not complete consistant, the reason may closely relate with the technical factors.
