Objective: To investigate whether certain polymorphisms are correlated with leiomyoma susceptibility, i.e., interleukin (IL)-1, IL-2, IL-4, IL-8, IL-12, and IL-18, which are all immunomodulatory cytokines that play important roles in host immune responses against cancers. Setting: Departments of gynecology and genetics in a medical center. Patient(s): Women were divided into: [1] a leiomyoma group (n = 162) and [2] a nonleiomyoma group (n = 156). Intervention(s): Genotyping for the IL-1 beta-511 promoter, IL-1 beta exon 5, IL-1Ra, IL-2 114, IL-4 -590 intron 3, IL-8 3'-UTR 2767, IL-12R beta 1 codon 378, and IL-18 105 were evaluated by polymerase chain reaction-restriction fragment length polymorphism. Main Outcome Measurement(s): Genotypes and allelic frequencies in both groups were compared. Result(s): Proportions of IL-12R beta 1 codon 378 *CC/CG/GG in the leiomyoma and nonleiomyoma groups were: [1] 7.4%/43.8%/48.8% and [2] 11.5%/54.5%/34%, respectively. Distributions of other polymorphisms in both groups were not significantly different. Proportions of IL-1 beta-511 promoter *CC/CT/TT were: [1] 22.8%/50%/ 27.2% and [2] 21.8%/57.1%/21.1% in the leiomyoma and nonleiomyoma groups, respectively. The IL-1 beta exon 5 *E1 homozygote/heterozygote/E2 homozygote were: [1] 96.3%/3.7%/0% and [2] 96.9%/3.1%/0% in the leiomyoma and nonleiomyoma groups, respectively. Alleles I/II/III/IV/V for IL-1Ra were: [1] 92.6%/7.1%/0.3%/ 0/0% and [2] 93.9%/5.7%/0%/0.4/0% in the leiomyoma and nonleiomyoma groups, respectively. The IL-2 114 G homozygote/heterozygote/T homozygote were: [1] 27.8%/49.4%/22.8% and [2] 20.5%/53.2%/26.3% in the leiomyoma and nonleiomyoma groups, respectively. The IL-4 -590 intron 3 *RP1 homozygote/heterozygote/ RP2 homozygote were: [1] 64.8%/32.7%/2.5% and [2] 69.2%/26.9%/3.9% in the leiomyoma and nonleiomyoma groups, respectively. The IL-8 3'-UTR 2767 A homozygote/heterozygote/G homozygote were: [1] 14.2%/ 43.8%/42% and [2] 20.5%/41.7%/37.8% in the leiomyoma and nonleiomyoma groups, respectively. The IL-18 *AA/AC/CC were: [1] 56.8%/40.7%/2.5% and [2] 59%/39.7%/1.3% in the leiomyoma and nonleiomyoma groups, respectively. Conclusion(s): The IL-12R beta 1 codon 378 *G homozygote and G allele are related to a higher susceptibility to leiomyoma. The IL-1 beta-511 promoter, IL-1 beta exon 5, and IL-1Ra, IL-2 114, IL-4 -590 intron 3, IL-8 3'-UTR 2767, and IL-18 105 gene polymorphisms are not correlated with the development of leiomyoma.

Endometriosis and leiomyoma display features similar to malignancy, requiring neovascularization to proliferation and growth. Altered vascular-related genes might be related to the development of endometriosis and leiomyoma. Polymorphisms of the angiotensin-converting enzyme (ACE) insertion/deletion (I/D) genes have been linked with some vascular diseases. This study investigates whether ACE I/D gene polymorphisms could be used as markers of susceptibility in endometriosis and leiomyoma. Women were divided into three groups: (4) endometriosis (n = 125); (2) leiomyoma (n = 120); () normal controls (n = 128). Genomic DNA was obtained from peripheral leukocyte. ACE I/D gene polymorphisms in intron 16 were amplified by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) Genotypes and allelic frequencies in both groups were compared. We observed the genotype distribution and allele frequency of ACE I/ D gene polymorphisms in both groups were significantly different. Proportions of ACE(star)I homozygote/ heterozygote/D homozygote in both groups were: (1) 50.4/24/25.6%; (2) 25/23.33/51.67%; (3) 10.2/ 29.7/60.1%. Proportions of I/D alleles in each group Were: (1) 62.4/37.6%; (2) 36.7/63.3%; (3) 25/75%. We concluded that ACE(star)I/D gene polymorphisms are associated with endometriosis and leiomyoma suspeptibilities. ACE(star)I-related genotypes and allele are strongly related to the occurrence of endometriosis and moderately related to the occurrence of leiomyoma.

Vascular endothelial growth factor (VEGF) is a regulator of angiogenesis and a mediator of sex steroid-induced cell growth and differentiation. We aimed to investigate if VEGF gene 5'-UTR -460 polymorphism could be used as markers of susceptibility in leiomyoma. Women were divided into two groups: (1) leiomyoma (n=159); (2) nonleiomyoma groups (n=131). VEGF gene-460 polymorphism were detected by polymerase chain reaction and BstUI restriction enzyme analysis. Genotypes and allelic frequencies between both groups were compared. We noted that the proportions of different VEGF polymorphisms in both groups were significantly different. Proportions of cuttable (C) homozygote/heterozygote/uncuttable (T) homozygote for VEGF in both groups were: (1) 0/32/68% and (2) 0/63/37%. Higher percentage of T homozygote and T allele presented in the leiomyoma population. Proportions of C/T alleles in both groups were: (1) 16/84% and (2) 32/68%. We concluded that T homozygotes and T allele of VEGF gene-460 polymorphism are associated with higher risk of leiomyoma development. Heterozygotes and C allele are related with lower risk of leiomyoma formation VEGF gene polymorphism likely contributes to the pathogenesis of leiomyoma.

Objectives: To investigate the roles of insulin-like growth factor II (IGF2), myeloperoxidase (MPO), E-cadherin (CDH1), urokinase and xeroderma pigmentosum group A and D (XPA, XPD) polymorphisms upon leiomyoma susceptibility. Study Design: Women were divided into: group I, leiomyoma (n=158); group 2, non-leiomyoma (n=156). Polymorphisms (IGF2 exon 9*A/G, MPO-463*A/G, CDH1-Pml I, urokinase-ApaL, XPA*A-23G, XPD*Lys751Gln) were amplified by polymerase chain reaction and detected by electrophoresis after restriction enzyme digestion. Genotype and allelic frequencies were compared between both groups. Results: Associations between leiomyoma with IGF2 and CDH1 polymorphism exist. Proportions of IGF2 exon 9*AA/AG/GG in and CDH1* CC/CT/TT in the groups were: group I, 38/39.2/22.8% and 27.8/66.5/5.7%; group 2, 22.4/53.9/23.7% and 21.2/64.1/14.7. MPO, urokinase, XPA and XPD in both groups were non-significantly different. Proportions of MPO*AA/AG/GG, urokinase*CC/CT/TT, XPA*AA/AG/GG and XPD*AA/AC/CC were: group 1: 1.9/23.4/74.7%, 0.6/7/92.4%, 20.9/55.1/24%, 85.4/14.6/0%; group 2: 3.8/24.4/71.8%, 1.3/4.5/94.2%, 22.4/53.9/23.7%, 84.6/15.4/0%. Conclusion: IGF2*A allele and CDH1*C allele were correlated with leiomyoma susceptibility, which may be associated with leiomyoma development. MPO, urokinase, XPA and XPD polymorphisms are not related to leiomyoma susceptibilities.
