Insulin signaling mediates neurodegeneration in gliomaTumoral cells secrete an antagonist that attenuates insulin signaling in neurons. It induces mitochondrial defects and synapse loss; restoring neuronal insulin activity rescues neurodegeneration.
A FIJI macro for quantifying pattern in extracellular matrixThis work provides a quantitative tool for the analysis of fibrillar patterns in biology. We demonstrates its utility on in vitro generated extracellular matrices, mouse tissues, and patient samples. The tool is already publicly available to the research community.
Different mutant RUNX1 oncoproteins program alternate haematopoietic differentiation trajectoriesUsing integrated genome-wide and phenotypic methods this study investigates four different mutant RUNX1 oncoproteins and reveals how they differentially contribute to aberrant haematopoiesis.
Genetic and stochastic influences upon tumor formation and tumor types in Li-Fraumeni mouse modelsThis study used mice heterozygous for Tp53 mutations with different genetic backgrounds to investigate the genetic or stochastic factors that modify the penetrance of tumor formation by Tp53 mutation.
Paneth cell–derived growth factors support tumorigenesis in the small intestinePaneth cells, known for their production of antimicrobial peptides and growth factors in the gut epithelium, are found to play a key role in intestinal tumor formation through secretion of Wnt3.
FAM83F regulates canonical Wnt signalling through an interaction with CK1αFAM83F directs CK1α to the plasma membrane, and through its association with CK1α, FAM83F mediates canonical Wnt signalling.
The chromatin landscape of primary synovial sarcoma organoids is linked to specific epigenetic mechanisms and dependenciesWe have addressed the mechanisms by which the fusion protein SS18-SSX modifies the epigenome toward the development of synovial sarcoma and the establishment of its potentially targetable vulnerabilities.
Requirement of DNMT1 to orchestrate epigenomic reprogramming for NPM-ALK–driven lymphomagenesisNPM-ALK–driven lymphoma in mice is dependent on MYC signaling and epigenomic reprogramming via DNA methyltransferases, resulting in heterogenous DNA methylation signatures reminiscent of human lymphoma.
Sustained Helicobacter pylori infection accelerates gastric dysplasia in a mouse modelHp infection was found to alter metaplasia and accelerate dysplasia in mice. Thus, Hp can promote gastric preneoplastic progression, in addition to its known role in initiating chronic inflammation.
Loss of Jag1 cooperates with oncogenic Kras to induce pancreatic cystic neoplasmsJag1 functions as a tumor suppressor in delaying pancreatic cancer precursor, while at the same time, promotes a phenotypic switch from benign cystic lesions to invasive carcinoma of the pancreas.
