Abstract
To establish a mouse lymphoma xenograft model so as to investigate the correlation between the expression of matrix metallopeptidase-9 (MMP-9) and that of B-cell lymphoma 2 (Bcl-2) in lymphomas. Diffuse large Bcl (DLBCL) cells were cultured, and a mouse lymphoma xenograft model was established via the subcutaneous injection. Mouse lymphoma tissues were extracted, and the expressions of MMP-9 and Bcl-2 messenger ribonucleic acids (mRNAs) in the xenograft tumor were detected using Real-time polymerase chain reaction (PCR). Immunohistochemistry was used to detect the expression levels of MMP-9 and Bcl-2 proteins in lymphoma tissues and tumor-adjacent tissues. The consistency of MMP-9 expression and Bcl-2 expression was analyzed via Spearman's rank correlation analysis. The expressions of MMP-9 and Bcl-2 in lymphoma tissues were increased. The expression levels of MMP-9 and Bcl-2 proteins in lymphoma tissues were higher than those in tumor-adjacent tissues. The expression levels of MMP-9 and Bcl-2 were correlated with the body weight loss degree of mice, and the expression of MMP-9 was positively associated with that of BCL-2 in lymphomas. MMP-9 and Bcl-2 are associated with the onset of DLBCL, and they are potential impact factors affecting the prognosis.
