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 ...

Beyond undulation! Body morphology and sensing components of elongated animals and robots reveal skills to maintain competent locomotion

Laura Isabel Paez Coy

Locomotion is an essential evolutive innovation of living beings that allows them to colonize and dominate the planet. As diverse as animal morphologies are (living) and were (extinct), their locomotion modalities are also diverse. In particular, animal mo ...

Automatic Body Segment and Side Recognition of an Inertial Measurement Unit Sensor during Gait

Kamiar Aminian, Xavier Crevoisier, Robin Martin

Inertial measurement unit (IMU) sensors are widely used for motion analysis in sports and rehabilitation. The attachment of IMU sensors to predefined body segments and sides (left/right) is complex, time-consuming, and error-prone. Methods for solving the ...

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 ...

Molecular architecture of the developing mouse brain

Gioele La Manno, Alex Russell Lederer, Irina Khven

The mammalian brain develops through a complex interplay of spatial cues generated by diffusible morphogens, cell-cell interactions and intrinsic genetic programs that result in probably more than a thousand distinct cell types. A complete understanding of ...

The box C/D snoRNP assembly factor Bcd1 interacts with the histone chaperone Rtt106 and controls its transcription dependent activity

Benjamin Marcel Daniel Rothé

Biogenesis of eukaryotic box C/D small nucleolar ribonucleoproteins initiates co-transcriptionally and requires the action of the assembly machinery including the Hsp90/R2TP complex, the Rsa1p:Hit1p heterodimer and the Bcd1 protein. We present genetic inte ...

Faster embryonic segmentation through elevated Delta-Notch signalling

Andrew Charles Oates

An important step in understanding biological rhythms is the control of period. A multicellular, rhythmic patterning system termed the segmentation clock is thought to govern the sequential production of the vertebrate embryo's body segments, the somites. ...

Reorganisation of Hoxd regulatory landscapes during the evolution of a snake-like body plan

Denis Duboule

Within land vertebrate species, snakes display extreme variations in their body plan, characterized by the absence of limbs and an elongated morphology. Such a particular interpretation of the basic vertebrate body architecture has often been associated wi ...

Body vibration and its transmission in alpine ski racing

Kamiar Aminian, Benedikt Fasel

The aim of the study was to quantify the vibrations occurring at the lower limbs and the trunk during alpine ski racing. Four European Cup level athletes skied each three runs on a typical giant slalom course. For each turn, power spectral density (PSD) of ...

Tetrapod axial evolution and developmental constraints; Empirical underpinning by a mouse model

Denis Duboule

The tetrapod vertebral column has become increasingly complex during evolution as an adaptation to a terrestrial life. At the same time, the evolution of the vertebral formula became subject to developmental constraints acting on the size of the cervical a ...

Different flavors of Toll guide olfaction

Bruno Lemaitre

Toll-like receptors are historically linked to immunity across animal phyla, but accumulating evidence suggests they play additional roles in neuronal networks and in cell-cell interactions. Ward and colleagues now identify Toll-6 and Toll-7 as instructive ...

A switch between topological domains underlies HoxD genes collinearity in mouse limbs

Didier Trono, Denis Duboule, Marion Leleu, Guillaume Andrey, Daniël Noordermeer

Hox genes are major determinants of the animal body plan, where they organize structures along both the trunk and appendicular axes. During mouse limb development, Hoxd genes are transcribed in two waves: early on, when the arm and forearm are specified, a ...

Anatomically plausible illusory posture affects mental rotation of body parts

Olaf Blanke, Silvio Ionta, Anna Sforza, Mariko Funato

During mental rotation (MR) of body parts, people internally simulate the movement of their corresponding body segments. These sensory-motor mechanisms render MR sensitive to proprioceptive information (e.g., posture). Similar mechanisms can alter illusory ...

Studies on KRAB/KAP1-Mediated Transcriptional Repression

Anna Claire Groner

The sequencing of the human genome revealed that the C2H2-zinc finger proteins (ZFPs) are the largest family of human transcription factors. Around 300 members of this family contain, in addition to their zinc finger motifs, a KRAB domain that has been imp ...

Atypical relaxation of structural constraints in Hox gene clusters of the green anole lizard

Denis Duboule

Hox genes control many aspects of embryonic development in metazoans. Previous analyses of this gene family revealed a surprising diversity in terms of gene number and organization between various animal species. In vertebrates, Hox genes are grouped into ...
