- An N-terminal–truncated isoform of FAM134B (FAM134B-2) regulates starvation-induced hepatic selective ER-phagy
This 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 checkpoint
Cells 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 identity
This 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 circles
AUG 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 recombination
Meiosis 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 growth
Inhibition 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 growth
This 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 corticogenesis
This 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.
- A dual role for SAMHD1 in regulating HBV cccDNA and RT-dependent particle genesis
Our study highlights a dual role for SAMHD1 in regulating hepatitis B virus cccDNA levels and reverse transcriptase–dependent particle genesis.
- let-7 coordinates the transition to adulthood through a single primary and four secondary targets
Although miRNAs may act through regulation of numerous targets, this study shows that the Caenorhabditis elegans let-7 miRNA promotes the juvenile-to-adult transition through repression of LIN41 alone, thereby activating four LIN41 targets that function in pairs to execute distinct developmental functions.
