An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Self‐Assembled Crystalline Peptoid Nanomaterials as Metal‐Free Enzyme Mimics for Enhanced Carbon Dioxide Hydration and Precipitation

Advanced Functional Materials, EarlyView.
Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

Advanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Calcium Binding Proteins

2012
The role of Ca(2+) as a key and pivotal second messenger in cells depends largely on a wide number of heterogeneous so-called calcium binding proteins (CBP), which have the ability to bind this ion in specific domains. CBP contribute to the control of Ca(2+) concentration in the cytosol and participate in numerous cellular functions by acting as Ca(2+)

Calcium binding by a myeloma protein

The American Journal of Medicine, 1979
We describe a patient with immunoglobulin G (IgG)-kappa myeloma and severe, long-standing, asymptomatic hypercalcemia. Serum nonprotein-bound calcium concentration was 5.2 mg/dl (normal 4.2 to 5.0 mg/dl) at a time when total serum calcium concentration was 17.8 mg/dl.

Sarcoplasmic calcium-binding protein

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995
Sarcoplasmic calcium-binding proteins (SCPs) are members of the EF-hand calcium-binding protein family which are characterized by the presence of helix-loop-helix motifs in their amino acid sequence. SCPs have an M(r) of approximately 20,000, a pI of approximately 5 and interact with two to three calcium ions (Ca2+) with a KD of 10(-7) to 10(-8) M. Mg2+

Calcium-binding proteins and development

Biometals, 1998
The known roles for calcium-binding proteins in developmental signaling pathways are reviewed. Current information on the calcium-binding characteristics of three classes of cell-surface developmental signaling proteins (EGF-domain proteins, cadherins and integrins) is presented together with an overview of the intracellular pathways downstream of ...
