MetabolomicsThe ULK3 kinase is a key determinant of keratinocyte self-renewal and tumorigenesis targeting the arginine methylome
Epigenetic mechanisms oversee epidermal homeostasis and oncogenesis. The identification of kinases controlling these processes has direct therapeutic implications. We show that ULK3 is a nuclear kinase with elevated expression levels in squamous cell carcinomas (SCCs) arising in multiple body sites,...

TranscriptomicsAsymmetric self-renewal associated (ASRA) genes
Cell lines geneticially engineered to undergo conditional asymmetric self-renewal were used to identify genes whose expression is asymmetric self-renewal associated (ASRA). Non-random sister chromatid segregation occurs concordantly with asymmetric self-renewal in these cell lines. Asymmetric self-...

ProteomicsFgf and Esrrb integrate epigenetic and transcriptional networks that regulate self-renewal of Trophoblast Stem Cells
Esrrb is a transcription factor implicated in embryonic stem (ES) cell self-renewal, yet its knockout causes intrauterine lethality due to defects in trophoblast development. Here we show that in trophoblast stem (TS) cells, Esrrb is a downstream target of fibroblast growth factor (Fgf) signalling a...

TranscriptomicsNRASG12V mediates leukemia self renewal [Microarray]
Mutant RAS oncoproteins activate signaling molecules that drive oncogenesis in multiple human tumors including acute myelogenous leukemia (AML). However, the specific function of these pathways in AML is unclear. To elucidate the downstream functions of activated NRAS in AML, we employed a murine mo...

GenomicsWdr5 mediates self-renewal and reprogramming via the embryonic stem cell core transcriptional network
The embryonic stem (ES) cell transcriptional and epigenetic networks are critical for the maintenance of ES cell self-renewal. However, it remains unclear whether components of these networks functionally interact and if so, what factors mediate such interactions. Here we show that WD-repeat protein...

GenomicsEpigenetic determinants of self-renewal in glioblastoma
We over-expressed an epigenetic regulator in a glioblastoma (GBM) primary culture from an adult patient. These GBM cells have cancer stem cell phenotypes, as they have self-renewal properties and tumor initiation potential when transplanted in immunocompromised mice. ATAC-seq was performed on cells ...

GenomicsMacroH2A1 regulates the balance between self-renewal and differentiation commitment in embryonic and adult stem cells
One of the most striking epigenetic alterations that occurs at the level of the nucleosome is the complete exchange of the canonical H2A histones for the macroH2A variant. Here, we provide insight in the function of this unique histone variant in embryonic and adult stem cells. Knockdown of macroH2A...
