Metabolic sexual dimorphism in hypothalamic Fezf1 neuron-specific BDNF knockout

open access: yesBiology of Sex Differences
Background Brain-derived neurotrophic factor (BDNF) is highly expressed in the hypothalamus where it exerts regulatory functions over neurogenesis, reproduction, energy balance, and metabolism.

Oligomerization-primed coiled-coil domain interaction with Ubc13 confers processivity to TRAF6 ubiquitin ligase activity

open access: yesNature Communications, 2017
Ubiquitin ligase TRAF6 catalyzes assembly of free polyubiquitin chains for TAK1 activation in the IL-1R/TLR pathways, but the mechanism underlying its processivity is unclear.

Patterning of the C. elegans 1° vulval lineage by RAS and Wnt pathways [PDF]

open access: yes, 2000
In C. elegans, the descendants of the 1° vulval precursor cell (VPC) establish a fixed spatial pattern of two different cell fates: E-F-F-E. The two inner granddaughters attach to the somatic gonadal anchor cell (AC) and generate four vulF cells, while ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

A large family of Dscam genes with tandemly arrayed 5′ cassettes in Chelicerata

open access: yesNature Communications, 2016
Drosophila Dscam1 and vertebrate clustered protocadherins (Pcdh) are known for their extraordinary isoform diversity. Here authors identify a shortened Dscam gene family in Chelicerata, which displays homology to Drosophila Dscam1, and employs splicing ...

No-signaling, entanglement-breaking, and localizability in bipartite channels

open access: yes, 2010
A bipartite quantum channel represents the interaction between systems, generally allowing for exchange of information. A special class of bipartite channels are the no-signaling ones, which do not allow communication. In Ref. [1] it has been conjectured
