AI Article Synopsis

  • The study focuses on biofunctional scaffolds that enhance the growth and development of mesenchymal stem cells (MSCs) for bone tissue engineering.
  • Researchers used an easy UV-crosslinking method to create gelatin electrospun fibrous (GEF) scaffolds that include important biomolecules like RGD peptide, hydroxyapatite nanoparticles, and BMP-2.
  • The presence of these biomolecules significantly boosts MSC adhesion, proliferation, and differentiation, suggesting a promising approach for designing effective scaffolds in tissue engineering.

Article Abstract

Biofunctional scaffolds that support the adhesion, proliferation, and osteo-differentiation of mesenchymal stem cells (MSCs) are critical for bone tissue engineering. In this study, a simple in situ UV-crosslinking strategy was utilized to fabricate gelatin electrospun fibrous (GEF) scaffolds with multiple biosignals, including cell adhesive Arg-Gly-Asp (RGD) peptide, osteo-conductive hydroxyapatite (HAp) nanoparticles, and osteo-inductive bone morphogenic protein-2 (BMP-2). The adhesion and proliferation of MSCs on the GEF scaffolds were improved by the incorporation of RGD. Meanwhile, the incorporation of HAp and BMP-2 enhanced osteo-differentiation of MSCs. The three incorporated bio-factors exert a synergistic effect on osteogenesis of MSCs in the GEF scaffolds. This strategy of incorporating multiple biomolecules could be used to fabricate crosslinked electrospun scaffolds of natural polymers for tissue-engineering applications.

The gene is nearly ubiquitously subjected to activating mutation in pancreatic adenocarcinomas (PDAC), occurring at a frequency of over 90% in tumors. Mutant KRAS drives sustained signaling through the MAPK pathway to affect frequently disrupted cancer phenotypes including transcription, proliferation and cell survival. Recent research has shown that PDAC tumor growth and survival required a guanine nucleotide exchange factor for RAS homolog family member A (RhoA) called GEF-H1.

Article Synopsis
  • The IA polymorphism is linked to both the Ankyrin Repeat and Kinase Domain-containing I gene (ANKK1) and the D2 dopamine receptor gene, posing challenges in understanding its role in addictions and psychiatric disorders due to unclear ANKK1 functions.
  • Research using SH-SY5Y neuroblastoma models shows that ANKK1 interacts with FARP1, a synapse protein, contributing to neuronal maturation and the activation of the Wnt/PCP pathway while promoting neuritogenesis.
  • Interactions between ANKK1 and WGEF are crucial for regulating RhoGTPases during neuronal differentiation, indicating that ANKK1 may play a significant role in organizing the brain's structural response related to IA-associated

Lead Identification of Novel Naphthyridine Derivatives as Potent SOS1 Inhibitors.

SOS1, a guanine nucleotide exchange factor (GEF), plays a critical role in catalyzing the conversion of KRAS from its GDP- to GTP-bound form, regardless of mutation status, and represents a promising new drug target to treat all KRAS-driven tumors. Herein, we employed a scaffold hopping strategy to design, synthesize, and optimize a series of novel binary ring derivatives as SOS1 inhibitors. Among them, compound (HH0043) displayed potent activities in both biochemical and cellular assays and favorable pharmacokinetic profiles.

Tight junctions are a barrier-forming cell-cell adhesion complex and have been proposed to regulate cell proliferation. However, the underlying mechanisms are not well understood. Here, we used cells deficient in the junction scaffold ZO-1 alone or together with its paralog ZO-2, which disrupts the junctional barrier.

The late stages of Golgi maturation involve a series of sequential trafficking events in which cargo-laden vesicles are produced and targeted to multiple distinct subcellular destinations. Each of these vesicle biogenesis events requires activation of an Arf GTPase by the Sec7/BIG guanine nucleotide exchange factor (GEF). Sec7 localization and activity is regulated by autoinhibition, positive feedback, and interaction with other GTPases.
