Novel ATR/PARP1 Dual Inhibitors Demonstrate Synergistic Antitumor Efficacy in Triple‐Negative Breast Cancer Models

open access: yesAdvanced Science, EarlyView.
Novel ATR/PARP1 dual inhibitors are developed for the first time. Advanced lead B8 effectively reduces cell viability in vitro and suppresses tumor growth in vivo, with better potency than ATRi and PARPi alone or in combination. Mechanistically, B8 induces apoptosis, arrests the cell cycle, and inhibits cancer cells colony formation, migration, and ...

A Novel OsMPK6‐OsMADS47‐PPKL1/3 Module Controls Grain Shape and Yield in Rice

open access: yesAdvanced Science, EarlyView.
OsMADS47 is identified as a key regulator governing rice grain morphology. Phosphorylation‐dependent regulation of its activity directs the development of slender versus round grains, modulating both yield and appearance. This mechanism bridges cellular signaling with transcriptional regulation, establishing a molecular framework for grain optimization.

Accuracy of position determination in Ca$^{2+}$ signaling [PDF]

open access: yes, 2019
A living cell senses its environment and responds to external signals. In this work, we study theoretically, the precision at which cells can determine the position of a spatially localized transient extracellular signal. To this end, we focus on the case, where the stimulus is converted into the release of a small molecule that acts as a second ...

Characterization of the Structure and Function of the Fourth Member of p38 Group Mitogen-activated Protein Kinases, p38δ*

open access: yesJournal of Biological Chemistry, 1997
We have cloned and characterized a new member of the p38 group of mitogen-activated protein kinases here termed p38δ. Sequence comparisons revealed that p38δ is approximately 60% identical to the other three p38 isoforms but only 40–45% to the other ...

Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

open access: yesAdvanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

Macrophage WEE1 Directly Binds to and Phosphorylates NF‐κB p65 Subunit to Induce Inflammatory Response and Drive Atherosclerosis

open access: yesAdvanced Science, EarlyView.
The present study shows that macrophage WEE1 drives NF‐κB activation and inflammatory atherosclerosis by directly phosphorylating p65 at S536. This finding illustrates a macrophage‐specific WEE1‐p65 axis in regulating inflammatory atherosclerosis and points out new directions to broaden the clinical applications for WEE1 inhibitors in atherosclerosis ...

MD and EPR studies of the structure and dynamics of the MTSL spin-labelled activation loop of the Aurora-A kinase [PDF]

open access: yesarXiv, 2015
The understanding of kinase structure is mostly based on protein crystallography, which is limited by the requirement to trap molecules within a crystal lattice. Therefore, characterisations of the conformational dynamics of the activation loop in solution are important to enhance the understanding of molecular processes related to diseases and to ...

Regulation of mitogen-activated protein kinases by a calcium/calmodulin-dependent protein kinase cascade.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1996
Membrane depolarization of NG108 cells gives rapid (< 5 min) activation of Ca2+/calmodulin-dependent protein kinase IV (CaM-KIV), as well as activation of c-Jun N-terminal kinase (JNK).

Neuronal FGF13 Inhibits Mitochondria‐Derived Damage Signals to Prevent Neuroinflammation and Neurodegeneration in a Mouse Model of Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
This study elucidates a novel role of FGF13 in manipulating neuronal fate via mitochondrial transfer. FGF13 is identified as a mitochondria‐stabilizing protein by interacting with mitochondrial proteins. Under stress, the decrease of neuronal FGF13 fails to retain mitochondria within the cytoplasm, leading to the release of damaged mitochondria to ...

Ultrasound‐Responsive Piezoelectric Membrane Promotes Osteoporotic Bone Regeneration via the “Two‐Way Regulation” Bone Homeostasis Strategy

open access: yesAdvanced Science, EarlyView.
Patients with osteoporosis face a higher risk of bone injury, mainly due to weakened osteogenic differentiation and bone formation, along with increased osteoclast differentiation and bone resorption activity, leading to bone homeostasis imbalance.
