ProteomicsCullin 4b modulates Wnt signaling and CRL4b targets Irgm1 to fuel intestinal stem cell stemness and niche
Background & Aims: Hierarchical organization of intestine relies on their stem cells by self-renew and producing committed progenitors. Although signals like Wnt are known to animate the continued renewal by maintaining intestinal stem cells (ISCs) activity, molecular mechanisms especially E3 ubiqui...

ProteomicsLoss of Drosophila nucleostemin 1 disrupts ribosomal protein homeostasis and rRNA processing to trigger apoptosis via the Xrp1/Irbp18 complex
In this study, we investigate the role of Ns1 in proliferating epithelial tissues using the Drosophila wing imaginal disc as a model. We demonstrate that knocking down Ns1 in wing discs leads to strong apoptosis. However, unlike the reported effect on overexpressed RPs, we did not observe nucleolar ...
