Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

A RAT MODEL OF ALZHEIMER´S DISEASE BASED ON ABETA42 AND PRO-OXIDATIVE SUBSTANCES EXHIBITS COGNITIVE DEFICIT AND ALTERATIONS IN GLUTAMATERGIC AND CHOLINERGIC NEUROTRANSMITTER SYSTEMS

Frontiers in Aging Neuroscience, 2016
Alzheimer´s disease (AD) is one of the most serious human, medical, and socioeconomic burdens. Here we tested the hypothesis that a rat model of Alzheimer´s disease (Samaritan; Taconic Pharmaceuticals, USA) based on the application of amyloid beta42 and ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Busy-Tone Multiple Access with Collision Avoidance and Detection for Ad-Hoc Networks [PDF]

, 2019
Busy-Tone Multiple Access with Collision Avoidance and Detection (BTMA/CAD) is introduced. BTMA/CAD integrates collision avoidance and collision detection mechanisms in ad-hoc networks of nodes with half-duplex radios by means of a single busy tone ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Receiver-Initiated Collision Avoidance in Multi-Hop Ad Hoc Networks

, 2008
— Previous analysis of collision avoidance in ad hoc networks with hidden terminals has focused on senderinitiated schemes, like the IEEE 802.11 distributed coordination function.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
