- The PI3K and MAPK/p38 pathways control stress granule assembly in a hierarchical manner
PI3K and p38 act in a hierarchical manner to enhance mTORC1 activity and stress granule formation; although PI3K is the main driver, the impact of p38 gets apparent as PI3K activity declines.
- Gene editing enables T-cell engineering to redirect antigen specificity for potent tumor rejection
Targeted integration of a tumor-reactive T-cell receptor into the TRAC locus using CRISPR-Cas9 and AAV6 redirects primary human T cells against tumor cells in vitro and in vivo.
- Dependence on Myb expression is attenuated in myeloid leukaemia with N-terminal CEBPA mutations
We show that for acute myeloid leukaemias with CEBPA mutations, the dependency of leukaemia growth and differentiation on the Myb transcription factor is related to the combination of N- and C-terminal mutations involved and how this affects overall gene expression.
- PISD is a mitochondrial disease gene causing skeletal dysplasia, cataracts, and white matter changes
This work demonstrates that pathogenic variants in PISD cause mitochondrial disease and suggests a novel mechanistic link whereby impaired lipid content in the inner mitochondrial membrane alters the activity of inner mitochondrial membrane proteases.
- Innate extracellular vesicles from melanoma patients suppress β-catenin in tumor cells by miRNA-34a
Operated cancer patients develop elevated levels of extracellular vesicles (EVs) in their blood stream, suppressing cancer cells through miRNA-34a.
- Optimized ChIP-seq method facilitates transcription factor profiling in human tumors
This study presents an optimized ChIP-seq protocol to enhance transcription factor profiling in human tumours, enabling the analysis of highly challenging samples, including core needle biopsies.
- A C/EBPα–Wnt connection in gut homeostasis and carcinogenesis
This research reveals an antagonism between C/EBPα expression and activated Wnt signaling in the human and mouse gut and suggests a tumor suppressor function of C/EBPα in human and murine intestinal cancer.
- Disruption of stromal hedgehog signaling initiates RNF5-mediated proteasomal degradation of PTEN and accelerates pancreatic tumor growth
Disrupting paracrine Hedgehog signaling in pancreatic cancer stroma through genetic deletion of fibroblast Smoothened leads to proteasomal degradation of fibroblast PTEN and accelerates tumor growth.
- MBNL1 alternative splicing isoforms play opposing roles in cancer
MBNL1 proteins lacking exon 7 (−ex7) are antisurvival factors with tumor suppressive role that cancer cells tend to down-regulate in favor of MBNL +ex7 isoforms.
- Vnn1 pantetheinase limits the Warburg effect and sarcoma growth by rescuing mitochondrial activity
Expression of the Vnn1 pantetheinase by sarcomas is tumor suppressive by limiting the use of aerobic glycolysis for growth and rescuing mitochondrial activity through CoA regeneration.
