Lack of Association between ESR1 and CYP1A1 Gene Polymorphisms and Susceptibility to Uterine Leiomyoma in Female Patients of Iranian Descent
Uterine leiomyonna (UL) is the most common benign smooth muscle cell tumor with as yet unknown etiology and pathogenesis. This study was carried out to investigate the association of ESR1-351 A>G, ESR1 -397 T>C and CYP1A1 (IIe462Val) polymorphisms with UL in female patients of Iranian origin. In this case-control study, 276 patients with UL and 156 healthy women were recruited. The genetic polymorphisms ESR1-351 A>G, ESR1-397 T>C and CYP1A1 (IIe462Val) were genotyped by polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP). No significant difference were found in frequencies of both genotypes and alleles of ESR1-351 A>G, ESR1-397 T>C and CYP1A1 (IIe462Val) polymorphisms between the two groups (p>0.05). Our findings indicated that these ESR1 and CYP1A1 polymorphisms were not associated with the development of UL in the cases reported here
Interleukin-1 β gene polymorphisms in Iranian patients with uterine fibroid, a case-control study
Uterine leiomyoma (UL) or fibroid is the most common estrogen- dependent tumor of the reproductive system. Almost a quarter of women at reproductive age are affected with this benign tumor. The purpose of the present study was to investigate the possible association of IL-1β-511and IL-1β 3954 polymorphisms with UL in the women of Charmahal & Bakhtiari province of Iran. Totally, 276 patients with UL and 157 healthy control women were studied. The genetic polymorphisms for IL-1β-511and IL-1β 3954 were analyzed by PCR-RFLP method. The results were analyzed with SPSS software using χ2 test. The TC genotypes of the IL-1β -511C/T polymorphism showed a decreased risk of UL (OR = 0.232, P = 0.01, 95 % CI = 0.11 - 0.48). A significant difference was found for the C allele frequencies of the IL-1 β -511 C>T polymorphism between the two groups (OR = 0.232, P = 0.01, 95% CI = 0.11 - 0.48). However, no significant difference was found for the IL-1 â -3954 polymorphism between the two groups. Our findings indicated that IL-1 â -511C>T promoter polymorphism affects the risk of UL in the women of our study and this polymorphism might be involved in the pathogens of this disease
Association of (Ile462Val in genetic polymorphisms CYP1A1) and uterine leiomyoma risk in women in Charmahal va Bakhtiari, I.R. Iran
زمینه و هدف: لیومیوم رحمی شایعترین تومور خوش خیم عضلات صاف رحم میباشد و تقریباً در ٢٥ تا ٣٠ زنان بالای ٣٠ سال رخ میدهد. رشد و پیشرفت لیومیوم وابسته به استروژن بود و نقش ژن سیتوکروم 450P- کلاس 1A1 (CYP1A1) در متابولیسم استروژن بررسی شده است. لذا این مطالعه با هدف بررسی ارتباط پلی مورفیسم Ile462Val (A>G) در ژن CYP1A1 با لیومیوم رحمی در زنان استان چهارمحال و بختیاری انجام شده است. روش بررسی: در این مطالعه مورد - شاهدی ١٥٦ زن با تشخیص کلینیکی لیومیوم رحمی و ١٥١ زن سالم به روش در دسترس انتخاب و مورد مطالعه قرار گرفتند. توزیع ژنتیکی پلی مورفیسم Ile462Val (A>G) ژن CYP1A1 با روش PCR-RFLP تعیین گردید. دادهها به کمک آزمون کای دو و t تجزیه و تحلیل شد. یافتهها: ژنوتیپ AG در زنان مبتلا به لیومیوم 2/12 (19 نفر) و در گروه شاهد 6/8 (13 نفر) بود. اختلاف معنیداری در فراوانی اللی و ژنوتیپی پلی مورفیسم ژن CYP1A1 بین دو گروه یافت نشد (306/0=P). نتیجهگیری: نتایج این مطالعه نشان داد که بین پلی مورفیسم ژن CYP1A1 (Ile462Val) و افزایش خطر لیومیوم در جمعیت زنان مورد مطالعه ارتباطی وجود ندار
