FANCJ couples replication past natural fork barriers with maintenance of chromatin structure
Defective DNA repair causes Fanconi anemia (FA), a rare childhood cancer-predisposing syndrome. At least 15 genes are known to be mutated in FA; however, their role in DNA repair remains unclear. Here, we show that the FANCJ helicase promotes DNA replication in trans by counteracting fork stalling on replication barriers, such as G4 quadruplex structures. Accordingly, stabilization of G4 quadru...
متن کاملNanog Overcomes Reprogramming Barriers and Induces Pluripotency in Minimal Conditions
Induced pluripotency requires the expression of defined factors and culture conditions that support the self-renewal of embryonic stem (ES) cells. Small molecule inhibition of MAP kinase (MEK) and glycogen synthase kinase 3 (GSK3) with LIF (2i/LIF) provides an optimal culture environment for mouse ES cells and promotes transition to naive pluripotency in partially reprogrammed (pre-iPS) cells. ...

متن کاملGenomic Stability: FANCJ-Dependent G4 DNA Repair
G-rich regions have the potential to form G4 DNA upon replication, which can lead to genomic instability. FANCJ, a G4 DNA helicase, has been shown to be critical for the stability of regions that match the G4 signature motif by experiments analyzing its nematode homolog.
متن کاملInhibition of Apoptosis Overcomes Stage-Related Compatibility Barriers to Chimera Formation in Mouse Embryos.
Cell types more advanced in development than embryonic stem cells, such as EpiSCs, fail to contribute to chimeras when injected into pre-implantation-stage blastocysts, apparently because the injected cells undergo apoptosis. Here we show that transient promotion of cell survival through expression of the anti-apoptotic gene BCL2 enables EpiSCs and Sox17+ endoderm progenitors to integrate into ...
