ABSTRACT

OBJECTIVE: To explore the association between polymorphism of cytochrome P450 1A1 Gene 3'-UTR (3'-untranslated region) 6235T-C and breast cancer with abnormal Hilit in Chinese Han population of Xinjiang. METHODS: The breast cancer patients were divided into four body fluids according to Uighur medical theories. And the technique of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was employed to detect the genotypic and allelic frequencies of 6235T-C polymorphism situated in 3'-untranslated region of CYP1A1 gene in 137 breast cancer patients with abnormal Hilit and 148 normal control subjects in Han population of Xinjiang province. RESULTS: (1) Significant differences in the genotypic and allelic distribution frequencies of CYP1A1 gene 3'-UTR6235T-C were found between breast cancer patients with abnormal Sapra Hilit and controls (χ(2) = 8.790, P = 0.012; χ(2) = 7.102, P = 0.008). The frequencies of CC genotype and C allele were significantly higher in breast cancer patients with abnormal Sapra Hilit (16.4% vs 39.8%) than in controls (4.7% vs 25.7%). (2) Significant differences in the genotypes and allelic distribution frequencies of CYP1A1 gene 3'-UTR6235T-C were found between breast cancer patients with abnormal Savda Hilit and controls (χ(2) = 6.638, P = 0.036; χ(2) = 5.824, P = 0.016). And the frequencies of TC, CC genotypes and C allele were significantly higher in breast cancer patients with abnormal Savda Hilit (56.9%, 9.8%, 39.2%) than those of the controls (41.9%, 4.7%, 25.7%). CONCLUSION: The CC genotype and C allele of 6235T-C polymorphism of CYP1A1 may be linked with breast cancer with abnormal Sapra Hilit and abnormal savda Hilit in Chinese Han population of Xinjiang province. But they are not correlated with the susceptibility to breast cancer with abnormal Balgham Hilit.

ABSTRACT

OBJECTIVE: To explore the association between polymorphism of dopamine 1 transporter variable number tandem repeat (DAT1 VNTR) and breast cancer with abnormal Hilit in Chinese Han population from Xinjiang. METHODS: The breast caner patients were divided into four body fluids according to Uighur medicine theory. And polymerase chain reaction and VNTR polymorphism technique were employed to detect genotypic and allelic frequencies of a 40 bp VNTR polymorphism situated in 3' untranslated region of DAT1 gene in 144 breast cancer patients with abnormal Hilit and 104 normal control subjects in Han population of Xinjiang province. RESULTS: In our sample, the repeat numbers of 40 bp were 7 and 9 - 11 (PCR product length of 360 bp and 440 bp to 520 bp) and 10-repeat allele (480 bp) detected was the dominant allele of DAT1 gene polymorphisms with an allelic frequency of 90.9%; Seven kinds of genotype were detected and genotype 10/10 was the most common genotype with a genotypic frequency of 83.1%. The frequency of 10-repeats allele and 10/10 genotype was significantly higher in breast caner patients with abnormal balgham Hilit than in controls (OR = 0.127, 95%CI 0.016 - 0.988, P = 0.026; OR = 0.134, 95%CI 0.018 - 1.016, P = 0.020) and breast caner patients with abnormal Sapra Hilit (OR = 0.132, 95%CI 0.016 - 1.075, P = 0.049; OR = 0.132, 95%CI 0.017 - 1.042, P = 0.033). CONCLUSION: The 10-repeats allele and 10/10 genotype of 40 bp VNTR polymorphism of DAT1 may increase the risk of breast cancer with Uighur medicine abnormal Hilit in Chinese Han population from Xinjiang province and it is not correlated with the susceptibility to breast cancer with Uighur medicine abnormal Sapra Hilit.

ABSTRACT

OBJECTIVE: To explore the association between patients with abnormal black Savda according to Uighur medicine theory and the serotonin transporter (5-HTT) gene polymorphisms in the promoter (5-HTTLPR) and the variable number tandem repeats (VNTRs) in intron 2 (5-HTTVNTR). METHODS: Divided the patients into four body fluids according to Uighur medicine theory, PCR was used to detect genotype and allele frequencies of 5-HTILPR and 5-HTTVNTR polymorphisms in 66 patients with abnormal black Savda (including 35 cases of hypertension, 19 cases of diabetes, 12 cases of cancer diagnosis) and 45 control subjects. RESULTS: No significant differences for the genotype frequency or the allele frequency of 5-HTTLPR and 5-HTTVNTR were revealed between patients with abnormal black Savda and control subjects. More control subjects tended to be of L/L genotype (15.56%) than hypertension with abnormal black Savda (5.72%). On the contrary, more cancer diagnosis with abnormal black Savda tended to be of L/L genotype (25.00%) and L (54.17%) allele than control subjects L/L genotype (15.56%) and L allele (37.78%). On the other hand, fewer control subjects tended to be of 10/10 genotype (4.45%) than diabetes with abnormal black Savda (10.53%) and cancer diagnosis with abnormal black Savda (8.34%). CONCLUSION: 5-HTTLPR L/L genotype may be a protective factor for hypertension with abnormal black Savda, 5-HTTLPR L/L genotype and L allele may be risk factors for cancer diagnosis with abnormal black Savda, 5-HTTVNTR 10/10 genotype may be risk factors for cancer diagnosis with abnormal black Savda and diabetes with abnormal black Savda.
