A CTCF-dependent mechanism underlies the Hox timer relation to a segmented body plan

During gastrulation, Hox genes are activated in a timesequence that follows the order of the genes along their clusters. This property, which is observed in all animals that develop following a progressive rostral-to-caudal morphogenesis, is associated wit ...

Hunting for the wavefront: investigation of somite boundary positioning in zebrafish

Arianne Bercowsky Rama

Somitogenesis is the rhythmic and sequential formation of somites, which are tissue blocks that give rise to segmented adult body structures including the vertebrae and associated muscle. Somite formation is controlled by the segmentation clock, a populati ...

High light quantity suppresses locomotion in symbiotic Aiptasia

Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz

Many cnidarians engage in endosymbioses with microalgae of the family Symbiodiniaceae. In this association, the fitness of the cnidarian host is closely linked to the photosynthetic performance of its microalgal symbionts. Phototaxis may enable semi-sessil ...

Diet modulates cecum bacterial diversity and physiological phenotypes across the BXD mouse genetic reference population

Johan Auwerx, Evan Graehl Williams

The BXD family has become one of the preeminent genetic reference populations to understand the genetic and environmental control of phenotypic variation. Here we evaluate the responses to different levels of fat in the diet using both chow diet (CD, 13-18 ...

Cytochrome c oxidase barcodes for aquatic oligochaete identification: development of a Swiss reference database

Régis Lionel Vivien

Introduction. Aquatic oligochaetes represent valuable indicators of the quality of sediments of watercourses and lakes, but their difficult identification based on morphological criteria compromises their more common use for eco-diagnostic analyses. This i ...

Delta-Notch signalling in segmentation

Andrew Charles Oates

Modular body organization is found widely across multicellular organisms, and some of them form repetitive modular structures via the process of segmentation. It's vastly interesting to understand how these regularly repeated structures are robustly genera ...

A unique coral biomineralization pattern has resisted 40 million years of major ocean chemistry change

Anders Meibom, Jaroslaw Hubert Stolarski, Isabelle Domart-Coulon

Today coral reefs are threatened by changes to seawater conditions associated with rapid anthropogenic global climate change. Yet, since the Cenozoic, these organisms have experienced major fluctuations in atmospheric CO2 levels (from greenhouse conditions ...

Assessing metal bioaccumulation from estuarine sediments: comparative experimental results for the polychaete Arenicola marina

The purpose of this paper is to compare three approaches for providing information on the bioaccumulation potential of metals from contaminated sediments to the deposit-feeding polychaete Arenicola marina. We present metal (Ag, As, Cd, Cu, Pb and Zn) bioac ...

White matter fiber tract segmentation in DT-MRI using geometric flows

Jean-Philippe Thiran, Patric Hagmann, Reto Meuli, Xavier Bresson, Olivier Cuisenaire, Lisa Jonasson

In this paper, we present a 3D geometric flow designed to segment the main core of fiber tracts in diffusion tensor magnetic resonance images. The fundamental assumption of our fiber segmentation technique is that adjacent voxels in a tract have similar pr ...
