Media coverage following our paper on cilia and topography induced differentiation. Following publication of Rebecca McMurrey's paper in Scientific Reports, Queen Mary issued a press release which led to a write up in The Scientist Magazine - Surface Texture Influences Differentiation . (December 2013)
Christmas Party and Sports. The Knight research group joined up with Dr Hazel Screen's group for a rather strange sporting event - Netball/hangman - which required a combination of physical and mental dexterity! This was followed by Christmas Dinner which required neither. (December 2013)
Three new primary cilia journal papers accepted from the group.The Knight research group have just had three new primary cilia journal papers accepted for publication. The first study from Dr Angus Wann is to be published in the journal Cilia and demonstrates the interaction of HIF signalling and primary cilia in response to inflammatory cytokines. Dr Jerome Irianto in collaboration with Prof Rosa Serra, had his paper accepted by Journal of Biomechanics on the effect of depletion of primary cilia on the mechanical properties of cartilage. Finally Dr Rebecca McMurrey, Dr Angus Wann and Dr Clare Thompson have had a paper accepted in Scientific Reports. Their study unravelled the role of primary cilia elongation in mediating stem cell wnt signalling and differentiation in response to micro grooved topography. (December 2013).
Our paper on development of a spinning-disk super resolution microscope published in PlosOne. Dr Neveen Hosny has published our paper on the development of a super resolution microscope system that she built during her post doc position in my group funded by an EPSRC discipline bridging grant in collaboration with Dr Ann Wheeler. The paper in Plos One and the associated Queen Mary press release has been picked up by various science websites and is to be written into a full article for The Biologist magazine. (October 2013). http://www.qmul.ac.uk/media/news/items/se/115135.html
Our paper has been published on why cat urine doesn't cause encrustation of urological stents. Recent research from MSc Bioengineering student, Manar Shafat, has just been published exploring the difference between cat urine and human urine in terms of the rate of encrustation of urological stents. Manar's work showed that the differences in the inorganic chemical composition of human and cat urine is not responsible for the difference in encrustation suggesting it is the different organic components that prevent encrustation in cats.

Dr Tony Poole visits and speaks at London Cilia meeting. Tony Poole from University of Otago (New Zealand), one of our long standing collaborators, visited our group on 2nd October and spoke at a meeting on primary cilia researcher that we organised here at Queen Mary. The meeting included Prof Cheetam (UCL Institute of Opthalmology), Dr Mittchinson & Prof Phil Beales (UCL Institute of Child Health), Dr Paul Chapple (QMUL WIlliam Harvey Research Institute) and members of these groups. (October 2013).
Clare Thompson passes her PhD viva. Many congratulations to Clare whos PhD examined the influence of mechanical and thermal stress on chondrocyte primary cilia and associated hedgehog signalling. Clare is continuing in the group as a post doc working on an AO Foundation grant looking at the effect of lithium on chondrocyte primary cilia and cartilage degradation. (September 2013).
MRC Grant Successful. We now have confirmation that the MRC will fund our grant entitled: 'Osteoarthritis may be treated as an environmental ciliopathy'. The grant tests the hypothesis that pathological cues such as mechanical loading and inflammatory cytokines, modulate primary cilia structure and function leading to the onset and progression of arthritis. The grant is in collaboration with Prof Phil Beales and Dr Hannah Mitchinson (UCL) and Dr Paul Chapple (QMUL) and Mr Manoj Ramachandran (Barts & The London NHS). (September 2013)
