A characterization of grapevine of GRAS domain transcription factor gene family.

GRAS domain genes are a group of important plant-specific transcription factors that have been reported to be involved in plant development. In order to know the roles of GRAS genes in grapevine, a widely cultivated fruit crop, the study on grapevine GRAS (VvGRAS) was carried out, and from which, 43 were identified from 12× assemble grapevine genomic sequences. Further, the genomic structures, synteny, phylogeny, expression profiles in different tissues of these genes, and their roles in response to stress were investigated.

Association between abortion and breast cancer: an updated systematic review and meta-analysis based on prospective studies.

Objective: Although positive association between abortion and breast cancer was frequently reported from case-control studies, results from prospective studies were still unclear. This study aimed to evaluate this association based on prospective studies.

Methods: PubMed, ISI Web of Knowledge and Embase were systematically searched for prospective studies on the association between abortion and breast cancer up to April 2014, supplemented by manual searches on the references.
