BACKGROUND
The interaction of vascular endothelial growth factor-C (VEGF-C)/VEGF-D/VEGF receptor-3 is considered to be a major driver of lymphangiogenesis, however the mechanism of this process remains unclear. We aimed to investigate the possible lymphangiogenic significance of synaptonemal complex protein 3 (SCP3) in non-small cell lung cancer (NSCLC).
METHODS
The expression of SCP3, VEGF-C, and VEGF-D were measured and examined a correlation between SCP3 and VEGF-C or VEGF-D in various human lung cancer cell lines. Subsequently, we assessed SCP3, VEGF-A, VEGF-B, VEGF-C, and VEGF-D expression in archival tumor tissues from 89 NSCLC patients with lymph node (LN) metastasis by combined immunohistochemistry with quantitative digital image analysis.
RESULTS
Positive correlations between SCP3 and VEGF-C expression (R = 0.743) and VEGF-D expression (R = 0.932) were detected in various human lung cancer cell lines. The high expression of SCP3, VEGF-A, VEGF-B, VEGF-C, and VEGF-D were detected in 24 (27.0%), 22 (24.7%), 27 (30.3%), 27 (30.3%), and 24 cases (27.0%), respectively. Notably, SCP3 positively correlated with VEGF-C and VEGF-D expression (for both, P < 0.001) and negatively correlated with VEGF-A and VEGF-B expression (P = 0.029 and P = 0.026, respectively). In multivariate analysis of patients with LN metastasis, SCP3 expression predicted worse overall survival (hazard ratio = 1.86, P = 0.008).
CONCLUSIONS
SCP3 is associated with lymphangiogenesis and provides insight into the SCP3-VEGF-C/VEGF-D axis based cancer therapy strategy.
背景
血管内皮生长因子-C（VEGF-C）/VEGF-D/VEGF受体-3的相互作用被认为是淋巴管生成的主要驱动因素，然而这一过程的机制仍不清楚。我们旨在研究联会复合体蛋白3（SCP3）在非小细胞肺癌（NSCLC）中可能的淋巴管生成意义。
方法
检测多种人肺癌细胞系中SCP3、VEGF-C和VEGF-D的表达，并分析SCP3与VEGF-C或VEGF-D之间的相关性。随后，我们通过联合免疫组织化学和定量数字图像分析，评估了89例有淋巴结（LN）转移的NSCLC患者存档肿瘤组织中SCP3、VEGF-A、VEGF-B、VEGF-C和VEGF-D的表达。
结果
在多种人肺癌细胞系中检测到SCP3与VEGF-C表达（R = 0.743）和VEGF-D表达（R = 0.932）呈正相关。SCP3、VEGF-A、VEGF-B、VEGF-C和VEGF-D的高表达分别在24例（27.0%）、22例（24.7%）、27例（30.3%）、27例（30.3%）和24例（27.0%）中被检测到。值得注意的是，SCP3与VEGF-C和VEGF-D表达呈正相关（两者P均<0.001），与VEGF-A和VEGF-B表达呈负相关（分别为P = 0.029和P = 0.026）。在对有LN转移患者的多因素分析中，SCP3表达预示总体生存期较差（风险比 = 1.86，P = 0.008）。
结论
SCP3与淋巴管生成相关，并为基于SCP3-VEGF-C/VEGF-D轴的癌症治疗策略提供了见解。
