miR-21, miR-26b, miR-221/222 and miR-126 play crucial roles in cervical cancer development. Studies have shown that polymorphisms in miRNA genes can affect miRNA expression, which might be associated with cancer development. Ten single-nucleotide polymorphisms (SNPs) in the miR-21, miR-26b, miR-221/222 and miR-126 genes (rs1292037, rs13137 in miR-21; rs2227255, rs2227258 in miR-26b; rs2858061, rs34678647, rs2858060, rs2745709 in miR-221/222; rs2297537, rs2297538 in miR-126) were selected, and genotyped in a total of 2176 individuals, including 435 patients with cervical intraepithelial neoplasia (CIN), 743 patients with cervical cancer (CC) and 998 healthy persons using TaqMan assays, and their associations with CIN and CC were evaluated. Our results showed significant differences for the rs2297538 genotypes between the CIN and CC groups (P = 0.001). In addition, our results also showed significant differences for the rs2297537 alleles between the CIN and CC groups (P = 0.003), and the C allele of rs2297537 might be associated with a decreased risk of CC (OR = 0.72, 95%CI: 0.58–0.90). At the inheritance analysis, between the CIN and control groups, the T/T-T/C genotype in rs1292037 and A/A-A/T genotype in rs13137 might be associated with an increased risk of CIN in the recessive model (OR = 1.61, 95% CI: 1.17–2.20 and OR = 1.58, 95% CI: 1.15–2.15). In addition, the C/C-T/T genotype of rs2745709 might be associated with a decreased risk of CIN in the overdominant model (OR = 0.66, 95% CI: 0.52–0.82). Between, CIN and CC group, the T/T-C/C genotype in rs1292037 and A/A-T/T genotype in rs13137 might be associated with an increased risk of CC in the overdominant model (OR = 1.43, 95% CI: 1.12–1.81 and OR = 1.42, 95% CI: 1.12–1.80). The rs2297538 G/G-A/G genotype might be associated with an increased risk of CC in the recessive model (OR = 2.83, 95% CI: 1.52–5.25). The rs2297537 2C/C + C/G genotype might be associated with a decreased risk of CC (OR = 0.71, 95% CI: 0.57–0.89) in the log-additive model. The rs2745709 T/T-C/C genotype might be associated with an increased risk of CC (OR = 1.44, 95% CI: 1.13–1.83) in the overdominant model. Our results indicate that rs2297538 and rs2297537 in miR-126, rs1292037 and rs13137 in miR-21, and rs2745709 in miR-221/222, may have important roles in the development of CIN or CC.

miR-21、miR-26b、miR-221/222和miR-126基因多态性与宫颈上皮内瘤变和宫颈癌的关联研究

miR-21、miR-26b、miR-221/222 和 miR-126 在宫颈癌发展中起关键作用。研究表明,miRNA 基因的多态性可以影响 miRNA 的表达,这可能与癌症的发展有关。miR-21、miR-26b、miR-221/222 和 miR-126 基因中的 10 个单核苷酸多态性 (SNP)(miR-21 中的 rs1292037、rs13137;miR-28680rs 中的 rs2227255、rs2227258、28680rs 48687 ; 、miR-221/222中的rs2745709;miR-126中的rs2297537、rs2297538),共对2176人进行基因分型,其中宫颈上皮内瘤变(CIN)患者435例,宫颈癌(CIN)患者743例,宫颈癌(98例)使用 TaqMan 检测的健康人,以及他们与 CIN 和 CC 的关联进行了评估。我们的结果显示 CIN 和 CC 组之间 rs2297538 基因型存在显着差异(P = 0. 001)。此外,我们的结果还显示 CIN 和 CC 组之间 rs2297537 等位基因的显着差异(P = 0.003),并且 rs2297537 的 C 等位基因可能与 CC 风险降低有关(OR = 0.72,95%CI:0.58 –0.90)。在遗传分析中,在 CIN 和对照组之间,rs1292037 中的 T/TT/C 基因型和 rs13137 中的 A/AA/T 基因型可能与隐性模型中 CIN 的风险增加有关(OR = 1.61, 95% CI:1.17–2.20 和 OR = 1.58,95% CI:1.15–2.15)。此外,rs2745709 的 C/CT/T 基因型可能与优势模型中 CIN 风险降低相关(OR = 0.66,95% CI:0.52–0.82)。在 CIN 和 CC 组之间,rs1292037 中的 T/TC/C 基因型和 rs13137 中的 A/AT/T 基因型可能与优势模型中 CC 风险增加有关(OR = 1.43,95% CI:1。12–1.81 和 OR = 1.42,95% CI:1.12–1.80)。rs2297538 G/GA/G 基因型可能与隐性模型中 CC 风险增加有关(OR = 2.83,95% CI:1.52–5.25)。在对数加法模型中,rs2297537 2C/C + C/G 基因型可能与 CC 风险降低有关(OR = 0.71,95% CI:0.57–0.89)。在优势模型中,rs2745709 T/TC/C 基因型可能与 CC 风险增加有关(OR = 1.44,95% CI:1.13–1.83)。我们的结果表明,miR-126 中的 rs2297538 和 rs2297537、miR-21 中的 rs1292037 和 rs13137 以及 miR-221/222 中的 rs2745709 可能在 CIN 或 CC 的发展中起重要作用。在对数加法模型中,rs2297537 2C/C + C/G 基因型可能与 CC 风险降低有关(OR = 0.71,95% CI:0.57–0.89)。在优势模型中,rs2745709 T/TC/C 基因型可能与 CC 风险增加有关(OR = 1.44,95% CI:1.13–1.83)。我们的结果表明,miR-126 中的 rs2297538 和 rs2297537、miR-21 中的 rs1292037 和 rs13137 以及 miR-221/222 中的 rs2745709 可能在 CIN 或 CC 的发展中起重要作用。在对数加法模型中,rs2297537 2C/C + C/G 基因型可能与 CC 风险降低有关(OR = 0.71,95% CI:0.57–0.89)。在优势模型中,rs2745709 T/TC/C 基因型可能与 CC 风险增加有关(OR = 1.44,95% CI:1.13–1.83)。我们的结果表明,miR-126 中的 rs2297538 和 rs2297537、miR-21 中的 rs1292037 和 rs13137 以及 miR-221/222 中的 rs2745709 可能在 CIN 或 CC 的发展中起重要作用。
