Vitamin D (VDR)-mediated signaling contributes to the cell signaling pathways that affect cancer development. This study is conducted on 104 patients diagnosed with non-Hodgkin's lymphoma (NHL) and 246 healthy subjects to investigate the link between five genetic variants spanning the VDR gene and the risk of this malignancy in Iranian subjects. The PCR-RFLP method was used for the analysis of BsmI (rs1544410), ApaI (rs7975232), FokI (rs2228570) and TaqI (rs731236) variants. A simple Tetra-ARMS-PCR technique was employed for the genotyping of the Cdx2 (rs11568820) variant. No significant link was found between both groups regarding ApaI (rs7975232) and FokI (rs2228570) variants (P > 0.05). Also, different genetic models of TaqI (rs731236), BsmI (rs1544410) and Cdx2 (rs11568820) polymorphisms were significantly correlated to decreased risk of NHL (Odd ratios <1). We found three haplotypes were strongly associated with an increased risk of NHL (P < 0.0001). Linkage-disequilibrium (LD) analysis showed a strong linkage between TaqI (rs731236) and BsmI (rs1544410) among NHL case and control subjects. Our findings indicated that functional variants of the VDR gene are linked to a decreased risk of NHL in our population. Further replication studies in different ethnic groups are needed to validate our results.

维生素 D 受体基因常见变异与非霍奇金淋巴瘤易感性之间的关联:病例对照研究

维生素 D (VDR) 介导的信号传导有助于影响癌症发展的细胞信号通路。本研究对 104 名诊断为非霍奇金淋巴瘤 (NHL) 的患者和 246 名健康受试者进行,以调查跨越 VDR 基因的五种遗传变异与伊朗受试者患这种恶性肿瘤的风险之间的联系。PCR-RFLP 方法用于分析 BsmI (rs1544410)、ApaI (rs7975232)、FokI (rs2228570) 和 TaqI (rs731236) 变体。使用简单的 Tetra-ARMS-PCR 技术对 Cdx2 (rs11568820) 变体进行基因分型。在 ApaI (rs7975232) 和 FokI (rs2228570) 变体方面,两组之间未发现显着联系(P > 0.05)。此外,不同的 TaqI 遗传模型 (rs731236),BsmI (rs1544410) 和 Cdx2 (rs11568820) 多态性与 NHL 风险降低显着相关(奇数比 <1)。我们发现三种单倍型与 NHL 风险增加密切相关(P < 0.0001)。连锁不平衡 (LD) 分析表明,在 NHL 病例和对照受试者中,TaqI (rs731236) 和 BsmI (rs1544410) 之间存在很强的联系。我们的研究结果表明,VDR 基因的功能变异与我们人群中 NHL 风险的降低有关。需要对不同种族进行进一步的复制研究来验证我们的结果。我们的研究结果表明,VDR 基因的功能变异与我们人群中 NHL 风险的降低有关。需要在不同种族群体中进行进一步的复制研究来验证我们的结果。我们的研究结果表明,VDR 基因的功能变异与我们人群中 NHL 风险的降低有关。需要在不同种族群体中进行进一步的复制研究来验证我们的结果。
