The hypoxia-response pathway modulates RAS/MAPK–mediated cell fate decisions in Caenorhabditis elegansAtmospheric oxygen levels modulate the RAS/MAPK signaling pathway in the nematode Caenorhabditis elegans through a cross-talk between the DELTA/NOTCH and hypoxia signaling pathways. These mechanisms may permit the animals to adapt their development to changes in the environment.
Loss of PGC-1α in RPE induces mesenchymal transition and promotes retinal degenerationSustained loss of PGC-1α in RPE cells triggers mitochondrial/autophagic dysfunction and oxidative damage resulting in epithelial dedifferentiation and mesenchymal transition. RPE dysfunction caused by deletion of the PGC-1 coactivators in vivo causes retinal degeneration.
An N-terminal–truncated isoform of FAM134B (FAM134B-2) regulates starvation-induced hepatic selective ER-phagyThis study has identified a novel truncated isoform of FAM134B (FAM134B-2) that regulates starvation-induced selective ER-phagy of secretory proteins such as ApoCIII through the activation of C/EBPβ.
Cellular response upon proliferation in the presence of an active mitotic checkpointCells that replicate with an active mitotic checkpoint remain capable to mount multiple times an efficient arrest, are bigger than unperturbed cells, rely more heavily on Cdh1, and have an altered protein expression profile.
Characterisation of class VI TRIM RING domains: linking RING activity to C-terminal domain identityThis study shows that members of the class VI TRIM E3 ligase family contain monomeric RING domains and display no ligase activity and may require additional regulatory events to promote ubiquitination.
Noncoding AUG circRNAs constitute an abundant and conserved subclass of circlesAUG circRNAs are highly abundant and conserved with an Alu-independent mode of biogenesis. Although AUG circRNAs contain the N-terminal ORFs, no evidence supports translation of these circRNAs.
The impact of poly-A microsatellite heterologies in meiotic recombinationMeiosis strongly influences the transmission and evolution of heterozygous poly-A repeats as measured experimentally in a large collection of single recombination products in a human hotspot.
CXXC5 mediates growth plate senescence and is a target for enhancement of longitudinal bone growthInhibition of the CXXC5–DVL interaction is a potential therapeutic strategy for height enhancement of children with growth retardation.
m6A-mRNA methylation regulates cardiac gene expression and cellular growthThis study provides evidence that m6A methylation is dynamically regulated during human and murine cardiac disease and highlights an important role of the m6A methylase Mettl3 in regulating cardiac growth by gene expression control.
Sequence and expression levels of circular RNAs in progenitor cell types during mouse corticogenesisThis study identifies circular RNAs (circRNAs) in specific cell types of the developing mammalian cortex. This resource addresses the complexity and potential significance of this elusive class of transcripts.
