09/2022 - Conversion of anterograde into retrograde trains is an intrinsic property of intraflagellar transport
Cilia or eukaryotic flagella are microtubule-based organelles found across the eukaryotic tree of life. Their very high aspect ratio and crowded interior are unfavorable to diffusive transport of most components required for their assembly and maintenance. Instead, a system of intraflagellar transport (IFT) trains moves cargo rapidly up and down the cilium (Figure 1A).1, 2, 3 Anterograde IFT, from the cell body to the […]
09/2022 - Deep Survival EWAS approach estimating risk profile based on pre-diagnostic DNA methylation: an application to Breast Cancer time to diagnosis
Previous studies for cancer biomarker discovery based on pre-diagnostic blood DNA methylation profiles, either ignore the explicit modeling of the time to diagnosis (TTD) as in a survival analysis setting, or provide inconsistent results. This lack of consistency is likely due to the limitations of standard EWAS approaches, that model the effect of DNAm at […]
09/2022 - Human TKTL1 implies greater neurogenesis in frontal neocortex of modern humans than Neanderthals
INTRODUCTION The evolutionary expansion of the neocortex and the concomitant increase in neuron production are considered to be a basis for the increase in cognitive abilities that occurred during human evolution. Endocast analyses reveal that the endocranial volume of modern humans and Neanderthals was similar, suggesting similar brain and neocortex size. But whether similar neocortex […]
09/2022 - The human RNA polymerase I structure reveals an HMG-like docking domain specific to metazoans
Transcription of the ribosomal RNA precursor by RNA polymerase (Pol) I is a major determinant of cellular growth, and dysregulation is observed in many cancer types. Here, we present the purification of human Pol I from cells carrying a genomic GFP fusion on the largest subunit allowing the structural and functional analysis of the enzyme […]
08/2022 - Quantification of spatial subclonal interactions enhancing the invasive phenotype of pediatric glioma
Diffuse midline gliomas (DMGs) are highly aggressive, incurable childhood brain tumors. They present a clinical challenge due to many factors, including heterogeneity and diffuse infiltration, complicating disease management. Recent studies have described the existence of subclonal populations that may co-operate to drive pro-tumorigenic processes such as cellular invasion. However, a precise quantification of subclonal interactions […]
