Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

open access: yesAdvanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore

Magnetic Bioprinting and Actuation of Stretchable Muscle Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
Human and murine myoblasts labeled with iron oxide nanoparticles are magnetically bioprinted into wrench‐shaped tissues, which are then anchored between two magnetic needles. Mechanical stretching of these tissues enhances both their maturation and functional performance. Abstract Engineering tissues with precise, long‐lasting shapes and the capability

Genetics of signal transduction in invertebrates

Current Opinion in Genetics & Development, 1994
Receptor tyrosine kinases regulate a number of different cell fate decisions during invertebrate development. Genetic analysis of the signal transduction pathways activated by these kinases suggests that they converge upon a common pathway involving Ras and a cascade of cytoplasmic kinases, diverging again in the nucleus with the regulation of specific

Genetic approaches to mechanosensory transduction

Current Opinion in Neurobiology, 1995
Genetic approaches in several organisms provide the means of solving a previously intractable problem: characterizing the molecular foundations of the mechanical senses. In nematode mechanosensory cells, members of a novel class of epithelial ion channel subunits have been implicated as components of a mechanically gated channel.

Chemical genetic analysis of signal transduction pathways

Expert Opinion on Therapeutic Targets, 2006
Covalent modification of proteins by phosphorylation represents a major mechanism of signal transduction that contributes to many physiological and pathophysiological processes. The enzymes that regulate protein phosphorylation (e.g., protein kinases and phosphatases) are, therefore, potential targets for the rational design of small-molecule drugs for
