Using High‐Throughput Screening to Identify Crosslinking Peptides That Control Cell‐Mediated Matrix Degradation

Advanced Healthcare Materials, EarlyView.
Protease‐degradable hydrogels mimic dynamic cell‐matrix interactions, but controlling hydrogel degradation is a challenge. We screen libraries of peptides to identify sequences that are primarily degraded by membrane‐localized proteases. Crosslinking hydrogels with these peptides enables cell to spread and migrate while reducing matrix degradation ...

Lysine-Directed Post-translational Modifications of Tau Protein in Alzheimer's Disease and Related Tauopathies

Frontiers in Molecular Biosciences, 2017
Tau is a microtubule-associated protein responsible mainly for stabilizing the neuronal microtubule network in the brain. Under normal conditions, tau is highly soluble and adopts an “unfolded” conformation.

Suppressing t(4;11) Acute Leukemia by Lipopolymer Nanoparticle Delivery of siRNA Targeting KMT2A::AFF1 with Enhanced Extrahepatic Delivery

Advanced Healthcare Materials, EarlyView.
This study introduces a new lipopolymer nanoparticle (LPNP) system that efficiently delivers siRNA to leukemia cells. The LPNPs silence the leukemia fusion gene KMT2A::AFF1, induce apoptosis, and decrease leukemia burden in mice. These results demonstrate the potential of LPNPs as a targeted siRNA therapy for acute lymphoblastic leukemia.

Linking metabolism and histone acetylation dynamics by integrated metabolic flux analysis of Acetyl-CoA and histone acetylation sites

Molecular Metabolism
Objectives: Histone acetylation is an important epigenetic modification that regulates various biological processes and cell homeostasis. Acetyl-CoA, a hub molecule of metabolism, is the substrate for histone acetylation, thus linking metabolism with ...

Induction of Nephron–Ductal Dual Lineages via Early Retinoic Acid Signaling Establishes a Platform for Fully Patterned Kidney Organoids

Advanced Healthcare Materials, EarlyView.
A simplified, co‐culture‐free protocol for kidney organoids that generate segmented nephrons, including collecting ducts, has been developed. Early low‐dose RA with FGF9 induces balanced anterior–posterior IM patterning and dual UE/MM lineage commitment. BMP7 enhances nephron progenitor maturation.

Chemoselective Characterization of New Extracellular Matrix Deposition in Bioengineered Tumor Tissues

Advanced Materials, EarlyView.
Understanding the bi‐directional crosstalk between cells and their surrounding extracellular matrix (ECM) is critical for tissue engineering. This study presents a chemoselective strategy for proteomic profiling of newly deposited ECM from resident cells.

Acetyl-CoA synthetase activity is enzymatically regulated by lysine acetylation using acetyl-CoA or acetyl-phosphate as donor molecule

Nature Communications
AbstractThe AMP-forming acetyl-CoA synthetase is regulated by lysine acetylation both in bacteria and eukaryotes. However, the underlying mechanism is poorly understood. The Bacillus subtilis acetyltransferase AcuA and the AMP-forming acetyl-CoA synthetase AcsA form an AcuA•AcsA complex, dissociating upon lysine acetylation of AcsA by AcuA.
