Planar cell polarity is a fundamental process during development, coordinating the alignment of neighboring cells within the plane of a tissue. A Human Frontier Science Program grant team from the USA, Israel and Japan, along with collaborators from Fudan University in China, has demonstrated a conserved role for Ankrd6 in regulating planar cell polarity in both the fruit fly and mouse.

Stem cell-derived neurons serve as attractive human neuronal model systems in health and disease. In order to understand in vitro neurogenesis, transcriptional changes over the time course of differentiation were analyzed and a network of key transcription factors that promoted the loss of pluripotency and rapid neurogenesis via progenitor states was revealed.

Metastasis is responsible for ~90% of cancer-associated mortality, yet progress has been slow in developing drugs that either specifically target metastasis or target cells with metastatic potential. Our study describes a new non-canonical Wnt pathway through Frizzled2 (Fzd2) that drives epithelial-mesenchymal transition (EMT) and tumor metastasis.

Directed cell migration has special importance in processes such as cancer metastasis, immune surveillance and development. In these different processes, cell migration enables cancer cells to reach blood vessels for metastasis, immune cells to move to a site of infection, or the production of morphogenetic events that pattern our body. Understanding this process is therefore crucial to target these different processes in different path-physiological conditions. During cell motility, cells dynamically...

Communication between neurons involves surface receptors, which can transform a chemical signal from the outside into a flux of ions across the cell membrane, i.e. an electrical signal. The new 3D structure of one of these receptors, the serotonin type 3 receptor, reveals its anatomy in detail and provides a snapshot of the full ion pathway.

An ongoing battle between KRAB zinc finger genes to control the invasion of mobile DNA elements has driven the evolution of greater complexity of primate genomes.

Ground-running birds have a striking ability to run over uneven terrain with agility and efficiency. In our HFSP supported work, we seek the fundamental task-level control priorities that underlie this suite of locomotion behaviors. We address this question with a novel combination of cross-species obstacle experiments and trajectory optimization modeling analysis. We deduce that birds from quail to ostrich, a 540-fold mass range, achieve such dynamic locomotion primarily by regulating leg safety...

This study establishes nucleotide-resolution regulatory DNA landscapes and their dynamics in response to environmental cues such as light and heat, key to shaping plant growth and development, by mapping DNase I hypersensitive site (DHSs) combined with genomic footprinting.

Classical genetics has typically focused on dissecting how genes or pathways control a given process within cells. However, many genes likely play roles in multiple processes, which are potentially linked to one another. Unravelling those multiple roles and links is a pressing challenge if we are to understand how healthy cells function normally as integrated systems and, conversely, how complex cellular pathologies arise in disease and how to fix them.

Photosynthesis converts light into chemical energy and is the prerequisite for life on earth. It is divided into the light reaction, which captures light energy and dark reaction, which fixes atmospheric CO2. The polysaccharide starch represents the primary end product of the photosynthesis and thus the main energy storage. In all photoautotrophic eukaryotes these reactions are localized in the chloroplast. During the night when photosynthesis is inactive, starch is degraded and exported as maltose...
