Las integrantes del Comité organizador, docentes de distintas cátedras de esta Facultad, partimos de considerar la importancia fundamental de posicionar al Departamento y sus producciones en el ámbito académico, de tal manera que nuestro hacer pudiera ser expuesto y compartido con docentes e investigadores de otros ámbitos. La propuesta surgió con la intención de abrir un espacio específico para el intercambio y la discusión de experiencias en relación con las escrituras de mujer, un tema de gran interés y actualidad en los ámbitos sociales, culturales y académicos de las últimas décadas. Escogimos la modalidad de coloquio a fin de impulsar la comunicación e intercambio de experiencias de todos los participantes en torno al tema. Elegimos así también algunos ejes temáticos que buscaron incentivar el diálogo de los estudios literarios con las distintas perspectivas de otros sistemas culturales, así como con las diversas áreas delos estudios humanísticos, y de las ciencias sociales en general; iniciativa que se vio muy gratamente recompensada con la asistencia y participación de expositores de distintas disciplinas, tanto de nuestra casa como de otras universidades y centros de estudios. Contamos además con la atención y grata compañía de un grupo de escritoras de las ciudades de Río Cuarto y Córdoba, quienes compartieron generosamente con los presentes sus intuiciones y vivencias como creadoras, en las Mesas organizadas para el cierre de ambas jornadas de trabajo. En el presente volumen, que recoge buena parte de estos trabajos, hemos organizado las exposiciones en cuatro partes, dedicadas a las escrituras del yo femenino; la literatura escrita por mujeres en distintos períodos histórico culturales; las construcciones y deconstrucciones de la identidad femenina; y los cuerpos de mujer, sus lugares sociales y trayectorias; una adaptación a este formato de algunos de los ejes temáticos convocantes en su momento para la presentación de trabajos de los expositores. Una quinta y última parte recoge las experiencias de mujeres escritoras, contadas por sus protagonistas, nuestras escritoras invitadas, quienes autorizaron gentilmente la inclusión de sus palabras en esta publicación.Fil: Martínez, María Victoria.

Genome-Wide Association Study in BRCA1 Mutation Carriers Identifies Novel Loci Associated with Breast and Ovarian Cancer Risk

BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7×10-8, HR = 1.14, 95% CI: 1.09-1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4×10-8, HR = 1.27, 95% CI: 1.17-1.38) and 4q32.3 (rs4691139, P = 3.4×10-8, HR = 1.20, 95% CI: 1.17-1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific associat

Abdominal aortic aneurysm is associated with a variant in low-density lipoprotein receptor-related protein 1

Abdominal aortic aneurysm (AAA) is a common cause of morbidity and mortality and has a significant heritability. We carried out a genome-wide association discovery study of 1866 patients with AAA and 5435 controls and replication of promising signals (lead SNP with a p value < 1 × 10-5) in 2871 additional cases and 32,687 controls and performed further follow-up in 1491 AAA and 11,060 controls. In the discovery study, nine loci demonstrated association with AAA (p < 1 × 10-5). In the replication sample, the lead SNP at one of these loci, rs1466535, located within intron 1 of low-density-lipoprotein receptor-related protein 1 (LRP1) demonstrated significant association (p = 0.0042). We confirmed the association of rs1466535 and AAA in our follow-up study (p = 0.035). In a combined analysis (6228 AAA and 49182 controls), rs1466535 had a consistent effect size and direction in all sample sets (combined p = 4.52 × 10-10, odds ratio 1.15 [1.10-1.21]). No associations were seen for either rs1466535 or the 12q13.3 locus in independent association studies of coronary artery disease, blood pressure, diabetes, or hyperlipidaemia, suggesting that this locus is specific to AAA. Gene-expression studies demonstrated a trend toward increased LRP1 expression for the rs1466535 CC genotype in arterial tissues; there was a significant (p = 0.029) 1.19-fold (1.04-1.36) increase in LRP1 expression in CC homozygotes compared to TT homozygotes in aortic adventitia. Functional studies demonstrated that rs1466535 might alter a SREBP-1 binding site and influence enhancer activity at the locus. In conclusion, this study has identified a biologically plausible genetic variant associated specifically with AAA, and we suggest that this variant has a possible functional role in LRP1 expression

Sex Differences in Clopidogrel Effects Among Young Patients With Acute Coronary Syndrome: A Role for Genetics?

Poorer health outcomes experienced by young women with acute coronary syndrome may be related to sex differences in the safety and efficacy of antiplatelet agents, such as clopidogrel. Polymorphisms in drug metabolism enzyme (cytochrome P450 [CYP] family) genes are independent factors for the variability in response to clopidogrel. However, a sex-specific impact of genetics to explain worse clinical outcomes in women has not been explored extensively. Therefore, our objective was to determine whether an interaction of sex with CYP variants occurs among users of clopidogrel, and if so, its impact on 1-year adverse clinical outcomes

Abdominal Aortic Aneurysm Is Associated with a Variant in Low-Density Lipoprotein Receptor-Related Protein 1

Abdominal aortic aneurysm (AAA) is a common cause of morbidity and mortality and has a significant heritability. We carried out a genome-wide association discovery study of 1866 patients with AAA and 5435 controls and replication of promising signals (lead SNP with a p value < 1 × 10−5) in 2871 additional cases and 32,687 controls and performed further follow-up in 1491 AAA and 11,060 controls. In the discovery study, nine loci demonstrated association with AAA (p < 1 × 10−5).

Study design for selection of the SNPs and genotyping of <i>BRCA1</i> samples.

<p>GWAS data from 2,727 <i>BRCA1</i> mutation carriers were analysed for associations with breast and ovarian cancer risk and 32,557 SNPs were selected for inclusion on the iCOGS array. A total of 11,705 <i>BRCA1</i> samples (after quality control (QC) checks) were genotyped on the 31,812 <i>BRCA1</i>-GWAS SNPs from the iCOGS array that passed QC. Of these samples, 2,387 had been genotyped at the SNP selection stage and are referred to as “stage 1” samples, whereas 9,318 samples were unique to the iCOGS study (“Stage 2” samples). Next, 17 SNPs that exhibited the most significant associations with breast and ovarian cancer were selected for genotyping in a third stage involving an additional 2,646 <i>BRCA1</i> samples (after QC).</p
