Ovarian stimulation is frequently used in many assisted reproductive technologies (ART) procedures to increase the number of dominant follicles. However, achieving the optimal response to ovarian stimulation without complications can be difficult. In our study, we predict that future ovarian stimulation procedures will be more individually catered to each patient. A study that established a predictor model for ovarian stimulation showed that genetic single nucleotide polymorphisms (SNP) are good predictive factors (Fauser et al., 2007). Thus the objective of this study was to determine if there was any association between the various parameters that measure the success of ovarian stimulation and FSHR, CYP19, ESRJ and ESR2 singe nucleotide polymorphisms (SNP). A total of two hundred and four women undergoing either in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) were genotyped to study the distribution of the different SNPs. Complete clinical information was available for a range of forty nine to seventy three women to study any association between genotype and basal FSH level (day 3), basal 17 -beta estradiol level, number of follicles, number of eggs and the level of 17-beta estradiol during hCG administration. The association was studied using the one way ANOVA test and linear regression model. There was a significant correlation between the CYP 19Al rs10046 genotypes and FSH level (p=0.004), number of follicles (p=0.03) and level of 17-beta estradiol during hCG administration (p=0.04). Also, FSHR rs2268263 genotype was significantly linked to FSH level between the G-allele group (A/G and G/G) and the homozygote A group (p=0.04). Taken all together, these results suggest that several genes-especially CYP 19AJ and FSHR rs2269263- play a significant role in determining the success of ovarian stimulation.

Повний текст джерелаBackground: Up to 60% of women with endometriosis have infertility symptoms. However, mechanisms remain unclear, mainly when there is no distortion of pelvic anatomy. The multifactorial etiology and polygenic involvement of this disease have been widely accepted. Aromatase is one of the most studied molecules and there are evidences of increased expression of its gene (CYP19A1) on eutopic and ectopic endometrium in endometriosis. This enzyme, codified by the CYP19A1 gene, converts androgens to estrogens and is normally present in granulosa cells, where it plays an essential role for the intrafollicle steroidogenic production. In vitrostudies by granulosa cells culture have demonstrated reduced aromatase activity in women with endometriosis. The scarcity of studies assessing expression of the aromatase gene (CYP19A1) on these target cells stimulated the proposal of this research. The aim of this study is to quantify aromatase gene expression, by real-time PCR, in mural lutein-granulose cells of women with endometriosis undergoing assisted reproduction techniques. Patients and Methods: a case-control study was conducted on 11 women with endometriosis and 11 with male or tubal causes of infertility submitted to ovarian hyperstimulation (HOC), with a total of 12 cycles for endometriosis and 11 for the control group. There was no difference between the groups regarding age or HOC parameters. Mural lutein-granulosacells were harvested from pre-ovulatory follicles during oocyte retrieval and properly isolated. Later, RNA extraction (clorophorm/isopropanol) and reverse transcription were performed. Real-time PCR was run to quantify RNAm products of aromatase gene normalized to those from the control gene, beta-actin (relative expression). All experiments were carried out in duplicate. Results: there was no difference between the groups regarding the gene expression of CYP19A1 (aromatase) gene on mural lutein-granulosa cells (p>0.05, Mann Whitney), even if we consider separately the different stages of endometriosis (control vs. minimal/mild vs. moderate/severe, p>0.05, Kruskall Wallis). Conclusion: These results suggest that aromatase may have a complex control of its gene expression on granulosa cells and, despite of previous evidences showing its reduced activity on these target cells in endometriosis, the gene expression seems not affected by the disease, according to this study.

Повний текст джерелаThe aromatase enzyme complex is responsible for converting androgens into estrogens in vertebrates. One of the key enzymes of this complex is the cytochrome P450arom gene expression and regulation of this enzyme is directly linked to sexual differentiation. Estrogen is essential for the development of the gonads and various physiological processes, ranging from normal growth to reproductive behavior. This study aimed to correlate the polymorphisms in the genes CYP19a CYP19b. In a first moment with three strains used in aquaculture (Chitralada, Supreme and GIFT) using thirty animals of each strain and, a second time only with the Supreme strain which has also the objective of analyzing the sex ratios found in both treatments at different temperatures of water and to establish possible relationships between them, analyzing the 122 animals treated at 25 ° C and 129 animals of treatment at 35 ° C. After extraction of DNA samples were subjected to PCR using primers designed to flank a region of interest. After confirmation of amplification samples were subjected to electrophoresis on Origins apparatus for identification of alleles. In the first study was identified that there is a polymorphism in the promoter region of CYP19b in the three strains. Were observed three alleles, ranging from 141 to 123 bp. Thus the primers for amplification of microsatellites in the regulatory region of the gene CYP19b were efficient, and therefore its use for identification of mutations in this region can be employed in the typical analysis of microsatellites. In the second study was identified that there is a polymorphism in the regulatory region of the gene 10 CYP19a, 5 alleles were observed. The proportion of females and males found in the treatment at 25 ° C was 1:2,3 1:2,88 and treatment at 35 ° C. However, it can be assumed that the polymorphism present in this portion of the regulatory region may be related to sex reversal found. Whereas the attempt to select individuals with polymorphisms in the regulatory region of the aromatase gene (and CYP19a CYP19b) is an essential study to evaluate the expression levels of both, so you can see how it is being expressed in individuals that will reverse or not , allowing for the reversal temperature with a higher proportion.
O complexo enzimático da aromatase é responsável pela conversão de andrógenos em estrógenos nos vertebrados. Uma das principais enzimas deste complexo é o citocromo P450arom e a regulação da expressão gênica desta enzima está diretamente ligada à diferenciação sexual. O estrogênio é essencial para o desenvolvimento das gônadas e diversos processos fisiológicos, que vão desde o crescimento normal até o comportamento reprodutivo. Este estudo teve como objetivo correlacionar o polimorfismo nos genes CYP19a e CYP19b. Em um primeiro momento com três linhagens utilizadas na piscicultura brasileira (Chitralada, Supreme e GIFT) utilizando trinta animais de cada linhagem e, em um segundo momento somente com a linhagem Supreme a qual tem-se o objetivo também de analisar as proporções de sexo encontrado em dois tratamentos com temperaturas diferentes da água e estabelecer possíveis relações entre eles, analisando 122 animais do tratamento a 25°C e 129 animais do tratamento a 35°C. Após a extração de DNA as amostras foram submetidas a PCR utilizando os primers desenhados para flanquear uma região de interesse. Após confirmação da amplificação as amostras foram submetidas à separação eletroforética no aparato Origins para identificação dos alelos. No primeiro estudo foi identificado que existe um polimorfismo na região promotora de CYP19b nas três linhagens. Foram observamos três alelos, variando entre 141 e 123 pb. Assim os primers para a amplificação de microssatélite na região regulatória do gene CYP19b foram 8 eficientes e, portanto, seu uso para identificação de mutações nesta região pode ser empregada na análise típica de microssatélite. No segundo trabalho foi identificado que há um polimorfismo na região regulatória do gene CYP19a, onde foram observados 5 padrões de bandas (supostamente alelos). A proporção de fêmeas e machos encontrada no tratamento a 25°C foi de 1:2,3 e de 1:2,88 no tratamento a 35°C. Contudo, supõe-se que o polimorfismo presente nesta porção da região regulatória pode estar relacionado à reversão sexual encontrada. Considerando a tentativa de selecionar indivíduos que apresentem polimorfismo na região regulatória dos genes da aromatase (CYP19a e CYP19b), é indispensável um estudo para avaliar os níveis de expressão de ambos, para que se possa observar como está sendo expressado em indivíduos que revertem ou não, possibilitando assim a reversão por temperatura com uma proporção mais elevada.
