Gαi1/3 Are Essential for BMP2‐Induced Osteogenesis by Bridging BMP Receptors to the Gab1 Signaling Complex

Advanced Science, EarlyView.
The Gαi1/3 protein is a crucial connecting protein closely related to the signal transduction process of bone formation‐related cytokines such as BMP2. Gαi1/3 mediates downstream signaling pathways such as Smads and MAPK by binding to adaptor proteins like Gab1, thereby promoting the osteogenic effect of BMSCs.

Use of mesenchymal stem cells seeded on the scaffold in articular cartilage repair

Inflammation and Regeneration, 2018
Articular cartilage has poor capacity for repair. Once damaged, they degenerate, causing functional impairment of joints. Allogeneic cartilage transplantation has been performed for functional recovery of articular cartilage.

Renal Tubular Epithelial CRLF1 Interacts With ITGB1 to Accelerate Fibrosis During the Transition From AKI to CKD

Advanced Science, EarlyView.
During renal fibrosis, SMAD3 acts as a transcription factor for CRLF1, promoting its expression and secretion. CRLF1 then binds to ITGB1 via an autocrine mechanism, activating the PI3K‐AKT signaling pathway to mediate renal fibrosis. This accelerates the progression from AKI to CKD, highlighting the therapeutic potential of targeting CRLF1 for ...

Systematic Multi‐Level Analyses Decode the Arthritis‐Neurodegeneration Axis With In Vivo Validation

Advanced Science, EarlyView.
Arthritis and neurodegeneration are usually studied as separate disorders, but this study connects them through population evidence, genetic inference, transcriptomic mapping, and mouse models. It highlights RNF40 as a context‐dependent joint‐brain candidate, induced in inflammatory joints yet functionally linked to dopamine‐neuron vulnerability ...

Imaging of cartilage repair procedures

Indian Journal of Radiology and Imaging, 2014
AbstractThe rationale for cartilage repair is to prevent precocious osteoarthritis in untreated focal cartilage injuries in the young and middle-aged population. The gamut of surgical techniques, normal postoperative radiological appearances, and possible complications have been described.

Ion‐Driven Regulation of Ca2+ Flow by Ti/Zn Composite Activates ERK/MAPK Signaling and Maintains Mitochondrial Homeostasis to Promote Macrophage‐Mediated Bone Regeneration

Advanced Science, EarlyView.
A 3D‐printed interpenetrating Ti/Zn composite enables sustained Zn2+ release to regulate intracellular Ca2+ redistribution, preserve mitochondrial homeostasis, activate ERK/MAPK signaling, and promote M2 macrophage polarization, thereby enhancing osteoimmune‐mediated bone regeneration and peri‐implant osseointegration.

Advances in articular cartilage repair

Injury, 2005
Many joint and systemic disorders may lead to cartilage defects. Partial thickness defects of the articular cartilage do not have healing potential. When the lesion reaches the subchondral bone, spontaneous healing may be observed, but consists of fibrocartilaginous tissue.
