Bi-steric mTORC1 inhibitors induce apoptotic cell death in tumor models with hyperactivated mTORC1
The Journal of Clinical Investigation, 2023 The PI3K/AKT/mTOR pathway is commonly dysregulated in cancer. Rapalogs exhibit modest clinical benefit, likely owing to their lack of effects on 4EBP1. We hypothesized that bi-steric mTORC1-selective inhibitors would have greater potential for clinical ...

Sea-level trend variability in the Mediterranean during the 1993–2019 period
Frontiers in Marine Science, 2023 Sea-level change is one of the most concerning climate change and global warming consequences, especially impacting coastal societies and environments. The spatial and temporal variability of sea level is neither linear nor globally uniform, especially ...

Poisson-Fermi Formulation of Nonlocal Electrostatics in Electrolyte Solutions
Computational and Mathematical Biophysics, 2017 We present a nonlocal electrostatic formulation of nonuniform ions and water molecules with interstitial voids that uses a Fermi-like distribution to account for steric and correlation efects in electrolyte solutions.

Steric Effects Govern the Photoactivation of Phytochromes
ChemPhysChem, 2016 AbstractPhytochromes constitute a superfamily of photoreceptor proteins existing in two forms that absorb red (Pr) and far‐red (Pfr) light. Although it is well‐known that the conversion of Pr into Pfr (the biologically active form) is triggered by a Z→E photoisomerization of the linear tetrapyrrole chromophore, direct evidence is scarce as to why this ...

FEBS Letters, EarlyView.Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

FEBS Letters, EarlyView.Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

FEBS Letters, EarlyView.Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.
