Chronic lymphocytic leukemia (CLL) involves the proliferation and increase of B-lymphocytes in the peripheral blood, bone marrow and lymphoid organs. This study evaluated the microRNAs miR-197, miR-26a and miR-27a as potential biomarkers for CLL. Eighty-two patients with CLL and 62 control subjects (CT) were investigated for these targets, using quantitative PCR (qPCR). A significant reduction of all microRNAs was observed in CLL compared to the controls (p < 0.001). Significant negative correlations were observed for the clinical staging groups. After adjusting for multiple logistic regression analysis, miR-197 and miR-26a remained as possible independent risk factors related to the CLL. Our data indicated good performance of this microRNAs as potential biomarkers in CLL.
慢性淋巴细胞白血病（CLL）涉及外周血、骨髓和淋巴器官中 B 淋巴细胞的增殖和增加。本研究评估了 microRNAs miR-197、miR-26a 和 miR-27a 作为 CLL 的潜在生物标志物。使用定量 PCR（qPCR）对 82 例 CLL 患者和 62 例对照（CT）进行了这些靶标检测。与对照组相比，CLL 中所有 microRNAs 的表达均显著降低（p<0.001）。临床分期组之间观察到显著的负相关。在进行多元逻辑回归分析调整后，miR-197 和 miR-26a 仍然是与 CLL 相关的可能独立危险因素。我们的数据表明，这些 microRNAs 作为 CLL 的潜在生物标志物具有良好的性能。
