Abstract
- Objective: To investigate the expression of miR-9 in B lymphocytes, B cell lymphoma and classical Hodgkin's lymphoma (cHL) cell lines and its significance.<br />Methods: CD19(+) B lymphocytes were sorted from normal lymph node by magnetic beads. Total cellular micro-RNA was extracted from cHL cell line L428, B cell lymphoma cell lines Ly1 and Ly10 (diffuse large B cell lymphoma), Raji cells (Burkitt's lymphoma) and CD19(+) B lymphocytes, respectively. These micro-RNAs were separately transformed into cDNA by reverse transcription. The expression levels of miR-9 were measured by fluorescence quantitative PCR. In situ hybridization was used to detect the expression of miR-9 in cell lines.<br />Results: The expression of miR-9 was high in L428 cells (104.44 ± 1.61), and low in cell lines of B cell lymphoma (Ly1: 2.17 ± 0.38; Ly10: 1 ± 0.015; Raji: 2.65 ± 0.89), and extremely low in CD19(+) B lymphocytes (0.0026 ± 0.00040). Compared with that in the other cell lines, the expression of miR-9 in L428 cells was statistically significant (P < 0.05). miR-9 localized in the cytoplasm diffusely and strongly in L428, but scattered and slightly with some prominent distribution around the nuclear membranes in Ly1 and Ly10, and only weakly in Raji.<br />Conclusions: miR-9 highly expressed in cHL cell line and might be a molecular marker for diagnosis and treatment of cHL.
