Eunapius fragilis Trinity transcriptome
2017-11-08
ABSTRACT Background: The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expression patterns in different groups...

Evolution of the sponge body plan: Wnt and the development of polarity in freshwater sponges
DownloadSpring 2014
Body polarity is a fundamental aspect of all multicellular organisms. Metazoans – animals – are monophyletic, but is body polarity homologous among all phyla? Sponges are considered to have branched off first from other animals and therefore studies of polarity formation in the simple sponge body...

One of the features that distinguishes eukaryotes from prokaryotes is the membrane trafficking system. This system underpins much of the functionality of the eukaryotic cell, and is necessary for feeding, motility and communication. Analyses aimed at addressing the evolution of this system have...

Evolutionary origins of sensation in metazoans: functional evidence for a new sensory organ in sponges
Download2014-02-11
Background One of the hallmarks of multicellular organisms is the ability of their cells to trigger responses to the environment in a coordinated manner. In recent years primary cilia have been shown to be present as ‘antennae’ on almost all animal cells, and are involved in cell-to-cell...

Emergent communication is a framework for machine language acquisition that has recently been utilized to train deep neural networks to develop shared languages from scratch and use these languages to communicate and cooperate. Previous work on emergent communication has utilized gradient-based...

Expansion of ruminant-specific microRNAs shapes target gene expression divergence between ruminant and non-ruminant species
Download2013
Kommadath, A., Bao, H., Meng, Y., Plastow, G. S., Stothard, P., Sun, X., Arantes, A. S., Guan, L. L.
Background Understanding how species-specific microRNAs (miRNAs) contribute to species-specific phenotypes is a central topic in biology. This study aimed to elucidate the role of ruminant-specific miRNAs in shaping mRNA expression divergence between ruminant and non-ruminant species. ...

The goal of this guide is to derive a better understanding of the biodiversity of sponges across the eastern Canadian Arctic. Specimens were collected during research cruises aboard the Canadian Coast Guard Ship (CCGS) Amundsen in October 2015, July 2016 and July 2017. Collection sites were...

Forkhead (Fox) proteins are transcription factors that function in many processes including development, metabolism and cell cycle regulation. This gene family is divided into subfamilies that appear to originate from a common ancestor. I have identified the evolutionary selection pressures...
