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 ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Critical Singular Problems in Carnot Groups
The Journal of Geometric AnalysisAbstract We consider a power-type mild singular perturbation of a Dirichlet semilinear critical problem settled in an open and bounded set in a Carnot group. Here, the term critical has to be understood in the sense of the Sobolev embedding.

Non symmetric quantum loop groups and critical convolution algebras
, 2023 37 pages. arXiv admin note: text overlap with arXiv:2302.01418We realize the quantum loop groups and shifted quantum loop groups of arbitrary types, possibly non symmetric, via the K-theoretical critical convolution algebras introduced by Varagnolo ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Multiplicity of solutions for gradient systems
Electronic Journal of Differential Equations, 2010 We establish the existence of nontrivial solutions for an elliptic system which is resonant both at the origin and at infinity. The resonance is given by an eigenvalue problem with indefinite weight, and the nonlinear term is permitted to be unbounded.

Business Groups in Emerging Markets: Paragons or Parasites? [PDF]
Diversified business (or corporate) groups, consisting of legally independent firms operating in multiple markets, are ubiquitous in emerging markets and even in some developed economies. The study of groups, a hybrid organizational form between firm and
