The emergence of animals from their unicellular ancestors is a major evolutionary event. Thanks to the study of diverse close unicellular relatives of animals, we now have a better grasp of what the unicellular ancestor of animals was like. However, it is unclear how that unicellular ancestor of animals became the first animals. To explain this transition, two popular theories, the choanoblastaea and the synzoospore, have been proposed. We will revise and expose the flaws in these two theories while ...

Multicellularity evolved repeatedly in the history of life, but how it unfolded varies greatly between different lineages. Dictyostelid social amoebas offer a good system to study the evolution of multicellular complexity, with a well-resolved phylogeny and molecular genetic tools being available. We compare the life cycles of the Dictyostelids with closely related amoebozoans to show that complex life cycles were already present in the unicellular common ancestor of Dictyostelids. We propose frost ...

Levels of social capital can change after a natural disaster; thus far, no study has examined how changes in social capital affect the mental health of disaster victims. In this study, we examined how predisaster social capital and its changes after a disaster were associated with the onset of mental disorders.

The World Health Organization (WHO) argues that governments can postpone declining capacity of older adults by providing sufficient support. Yet, to our knowledge, no study has focused on the role of local governments for realizing healthy ageing. This study examined the association between the intensity of community-based programs for frailty postponement by long-term care insurers (as municipalities) and the likelihood of frailty. We analyzed repeated cross-sectional data of three waves (2010-11, ...

The Dictyostelid social amoebas are a popular model system for cell- and developmental biology and for evolution of sociality. Small subunit (SSU) ribosomal DNA-based phylogenies subdivide the known 150 species into four major and some minor groups, but lack resolution within groups, particularly group 4, and, as shown by genome-based phylogenies of 11 species, showed errors in the position of the root and nodes separating major clades. We are interested in the evolution of cell-type specialization, ...

A major hallmark of multicellular evolution is increasing complexity by the evolution of new specialized cell types. During Dictyostelid evolution novel specialization occurred within taxon group 4. We here aim to retrace the nature and ancestry of the novel "cup" cells by comparing their transcriptome to that of other cell types.RNA-Seq was performed on purified mature spore, stalk and cup cells and on vegetative amoebas. Clustering and phylogenetic analyses showed that cup cells were most similar ...

The endometrial stromal fibroblast (ESF) is a cell type present in the uterine lining of therian mammals. In the stem lineage of eutherian mammals, ESF acquired the ability to differentiate into decidual cells in order to allow embryo implantation. We call the latter cell type “neo-ESF” in contrast to “paleo-ESF” which is homologous to eutherian ESF but is not able to decidualize. In this study, we compare the transcriptomes of ESF from six therian species: Opossum (Monodelphis domestica; paleo-ESF), ...

Multicellular organisms are composed of distinct cell types that have specific roles in the body. Each cell type is a product of two kinds of historical processes—development and evolution. Although the concept of a cell type is difficult to define, the cell type concept based on the idea of the core regulatory network (CRN), a gene regulatory network that determines the identity of a cell type, illustrates the essential aspects of the cell type concept. The first step toward elucidating cell type ...

A challenge of genome annotation is the identification of genes performing specific biological functions. Here, we propose a phylogenetic approach that utilizes RNA-seq data to infer the historical relationships among cell types and to trace the pattern of gene-expression changes on the tree. The hypothesis is that gene-expression changes coincidental with the origin of a cell type will be important for the function of the derived cell type. We apply this approach to the endometrial stromal cells ( ...

We summarize evolutionary innovations that enable this form of vivipary, including early maternal recognition of pregnancy, invasive placentation, and emergence of the decidual cell type. We first review the structure of the marsupial endometrium and its relationship to that of eutherian mammals. While the tissue components of endometrium are the same in marsupials and eutherians, ...

Molecular phylogenetic studies suggest that the hemochorial placentation and decidualization are ancestral traits of eutherian mammals.

The impact of loci that determine sexual identity upon the asexual, dominant stage of fungal life history has been well studied. To investigate their impact, expression differences between strains of different mating type during asexual development were assayed, with RNA sampled from otherwise largely isogenic mat A and mat a strains of Neurospora crassa at early, middle, and late clonal stages of development. We observed significant differences in overall gene expression between mating types across ...
