CAVPENET Peptide Inhibits Prostate Cancer Cells Proliferation and Migration through PP1γ-Dependent Inhibition of AKT Signaling

open access: yesPharmaceutics
Protein phosphatase 1 (PP1) complexes have emerged as promising targets for anticancer therapies. The ability of peptides to mimic PP1-docking motifs, and so modulate interactions with regulatory factors, has enabled the creation of highly selective ...

Responses of Phycomyces indicating optical excitation of the lowest triplet state of riboflavin [PDF]

open access: yes, 1976
Phototropic and light growth responses of the sporangiophore of Phycomyces have been elicited using tunable laser stimulation from 575 to 630 nm. The growth response shows additional components of the action spectrum with a sharp peak at 595 nm, a sharp ...

Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

open access: yesAdvanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

Mechanotransduction Activates Microglia and Impairs Phagocytosis in Stiff Amyloid‐β Plaques

open access: yesAdvanced Science, EarlyView.
The study constructs an in vitro Aβ plaque‐associated microglia model and uses SECM and SICM to in situ monitor changes in ROS levels, membrane permeability, and phagocytosis of microglia during Aβ clearance. It is found out that Aβ stiffness triggers microglial activation via the PIEZO1 mechanotransduction pathway, causing neuroinflammation and ...

Phytophthora Disrupts Plant Immunity by Manipulating Nitric Oxide Homeostasis Through GSNOR Inhibition

open access: yesAdvanced Science, EarlyView.
Phytophthora capsici effector PcRD18 targets tomato GSNOR to disrupt NO homeostasis, promoting S‐nitrosylation of immune proteins like RBOHD. This suppresses ROS bursts and promotes pathogen infection. Mutation of the PcRD18‐binding sites of GSNOR avoids pathogen manipulation and offers a strategy to enhance crop resistance. Abstract Nitric oxide (NO),

Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

open access: yesAdvanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

USP8‐Governed MDA5 Homeostasis Promotes Innate Immunity and Autoimmunity

open access: yesAdvanced Science, EarlyView.
This study reveals that USP8 stabilizes MDA5 via AKT‐mediated phosphorylation (Ser718), enhancing their interaction and MDA5 deubiquitination. USP8 inactivation degrades MDA5, suppressing type I IFN and cytokine production. Pharmacological inhibition of USP8/AKT alleviates MDA5‐driven autoimmunity, demonstrating the USP8‐MDA5 axis as a therapeutic ...

Protocol for live-cell Förster resonance energy transfer imaging to reveal the bistable insulin response of single C2C12-derived myotubes

open access: yesSTAR Protocols
Summary: Based on our hypothesis that myotubes exhibit a bistable response to insulin, here we present a protocol for finely measuring Akt phosphorylation in single myotubes under insulin stimulation.

Peptide‐Carbazolyl Cyanobenzene Conjugates: Enabling Biomolecule Functionalization via Photoredox and Energy Transfer Catalysis

open access: yesAngewandte Chemie, EarlyView.
We introduce two methods for incorporating carbazolyl cyanobenzenes onto peptides: a C‐terminus decarboxylative functionalization and a Cys‐selective SNAr reaction. Both conjugates exhibit excellent photoredox/energy‐transfer properties, enabling their use for C‐terminal alkynylation and Cys‐selective thiol‐ene reactions on peptides, as well as ...
