Nonmulberry Silk Fibroin Doping Boosts Charge Transfer and Charge Injection in Aligned Polypyrrole‐Silk Scaffolds for Low‐Voltage Neurostimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Conductive silk‐polypyrrole scaffolds couple redox stability with cell‐affinitive peptides present innately in an endogenous silk fibroin, enabling optimized electrical stimulation to drive neurite outgrowth. Findings establish electrochemical‐biological link for biomaterial design rules for smart nerve guidance conduits that can provide low voltage ...

HPLC-MS characterisation of chelate modified somatropin [PDF]

open access: yes, 2010
Somatropin is a recombinant human growth hormone, consisting of 191 amino acids. This protein is clinically used in children and adults with inadequate endogenous growth hormone to stimulate a normal bone and muscle growth.

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Identification of PKN2 and MOB4 as Coordinators of Collective Cell Migration

open access: yesAdvanced Science, EarlyView.
Through a genetic screen, PKN2 and MOB4 are identified as two proteins regulating the healing of an epithelial model wound. PKN2 promotes collective cell migration by maintaining the cohesion of cell monolayers from their lateral junctions, whereas MOB4 restrains collective cell migration and provides a lamellipodial cue for front‐rear polarity in ...

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

open access: yesAdvanced Science, EarlyView.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Novel serine proteases in spinach plants [PDF]

open access: yes, 1985
分泌タンパク質や細胞内小器官に局在するタンパク質の多くは、前駆体タンパク質として合成され、合成および移送の過程で限定分解を受けた後、成熟タンパク質として機能することが知られている。この限定分解に関与するproteasesの研究は動物・植物を問わずほとんど進展をみていない現状にある。本研究はホウレンソウを用いて、細胞内に微量に存在する膜結合性のserine proteasesを検出し、あわせて酵素としての性質を明らかにしたものであり、4章から成る。 ・・・Thesis--University of ...

Vitamin D Regulates Olfactory Function via Dual Transcriptional and mTOR‐Dependent Translational Control of Synaptic Proteins

open access: yesAdvanced Science, EarlyView.
Vitamin D (VitD) modulates olfactory function by remodeling dendrodendritic synapses in tufted cells through vitamin D receptor‐dependent transcriptional and translational mechanisms. VitD regulates synaptic protein translation partially via mTOR signaling.

Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

open access: yesAdvanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.
