GWAS of 126,559 individuals identifies genetic variants associated with educational attainment

A genome-wide association study (GWAS) of educational attainment was conducted in a discovery sample of 101,069 individuals and a replication sample of 25,490. Three independent single-nucleotide polymorphisms (SNPs) are genome-wide significant (rs9320913, rs11584700, rs4851266), and all three replicate. Estimated effects sizes are small (coefficient of determination R(2) approximately 0.02%), approximately 1 month of schooling per allele. A linear polygenic score from all measured SNPs accounts for approximately 2% of the variance in both educational attainment and cognitive function. Genes in the region of the loci have previously been associated with health, cognitive, and central nervous system phenotypes, and bioinformatics analyses suggest the involvement of the anterior caudate nucleus. These findings provide promising candidate SNPs for follow-up work, and our effect size estimates can anchor power analyses in social-science genetics.

Diário da Constituinte [gravação de vídeo] : [programa n. 559]

Continua a polêmica em torno da Reforma Agrária. Constituintes discutem o conceito de terra produtiva. Alguns constituintes alegam ter havido fraude na votação da Emenda Paulinelli, que garante que as terras produtivas não sejam desapropriadas. No próximo título da Carta,os constituintes vão definir a Ordem Social. Alguns entendimentos já foram feitos para votar o capítulo da Saúde. Saúde será um direito de todos e dever do Estado. Caberá ao Poder Público, regulamentar, fiscalizar e promover ações de saúde. Todas as mudanças estão dentro da criação do Sistema Unificado de Saúde, mas os serviços serão descentralizados.

Cyt b-559 链Arg18和Ser24的定点突变及其对PSII功能的影响

Cyt b-559是光系统II反应中心的成分之一，它由亚基和亚基组成的。在Cyt b-559中，血红素辅基与两个亚基中的组氨酸连接成有功能的蛋白，并维持PSII的功能稳定性。前人曾将与血红素相连的His突变，导致Cyt b-559功能和PSII稳定性的丧失。基于此研究，本文采用定点突变技术，将亚基中与His23位置最近的上游氨基酸Arg18分别用Gly和Glu取代，下游氨基酸Ser24用Phe取代，获得了衣藻Cyt b-559的突变体。对突变体的分析，有以下新结果：突变体都能进行光合自养，但无论在异养培养基上还是自养培养基上，和对照相比，其生长速度非常缓慢; PSII的活性分析，表明PSII的放氧活性为野生衣藻细胞的50%～80%， Fv/Fm 的荧光参数为40%～70%;对突变体进行强光（1000μE•m-2•s-1）照射，10min后，其放氧活性都降低为0，而野生型衣藻还保持35%的活性;提取类囊体膜蛋白，进行SDS-PAGE电泳和Western-blotting分析，显示突变体的膜蛋白与对照无显著差异。这些结果说明对围绕血红素环境的固有氨基酸的改变，虽然并没有明显影响类囊体膜蛋白的表达和组成，但是却影响了衣藻细胞的生长和PSII的活性，增加了衣藻细胞对强光的敏感性，降低了衣藻细胞自身的光保护能力。这说明靠近血红素配位环境的氨基酸Arg和Ser，尤其是Arg，对Cyt b-559的功能维持不可缺少，对于维持PSII的活性也很重要。
