ABSTRACT
<p><b>OBJECTIVE</b>To establish Raji adriamycin (ADR)-resistant cell lines and analysis the expression of mitochondria Prohibitin (PHB) and microRNA-27a (miR-27a), as well as discuss its clinical significance.</p><p><b>METHODS</b>Built ADR-resistant Raji cells, detected their resistant index and drug-resistant spectrum and stability, observed their morphology and growth characteristics in general; evaluated the expression of phb mRNA and miR-27a in ADR-resistant cells (Raji/A) and sensitive cells (Raji/S) via real-time quantitative polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>The ADR-resistant Raji cell lines were built; expression of PHB1 mRNA in Raji/A was evidently higher than in Raji/S (P<0.05), the expressing difference of PHB2 mRNA in Raji/A and Raji/S was statistically meaningless (P>0.05), the expression of miR-27a in Raji/A was much higher than in Raji/S (P<0.05).</p><p><b>CONCLUSION</b>By building the experimental model of Raji ADR-resistant cell lines, high expression level of PHB1 and miR-27a were detected in the cell lines, indicating that PHB1 and miR-27a may be associated with ADR-resistance of Raji cells.</p>
