Senescent Fibroblasts Drive FAP/OLN Imbalance Through mTOR Signaling to Exacerbate Inflammation and Bone Resorption in Periodontitis.

Fibroblast activation protein (FAP), predominantly expressed in activated fibroblasts, plays a key role in inflammatory bone diseases, but its role in periodontitis remains unclear. Accordingly, this study identified a positive association between FAP levels and periodontitis susceptibility using Mendelian randomization analysis. Human and mouse periodontitis tissues show elevated FAP and reduced osteolectin (OLN), an endogenous FAP inhibitor, indicating a FAP/OLN imbalance.

Methods: A total of 798 patients with 2156 impacted third molars were collected from three centres between 1 December 2018 and 15 December 2018. ERR was identified by cone beam computed tomography examinations.

Split G-Quadruplex Programmed Recyclable AIE-Biosensor for Label-Free Detection of miRNA in Acute Kidney Injury.

We herein rationally designed a target-recyclable AIE-biosensor based on a split G-quadruplex for label-free detection of miRNA in acute kidney injury. Initially, the PG was in an "OFF" state, and the two split segments (G4-a and G4-b) of G4 were tethered at the two terminals of P1 and far away from each other due to the rigid duplex structure formed by the partially complementary intermediate sequences of P2 and P1, bringing MG with quenched fluorescence. In the presence of target, the 5'-PO P2 was displaced from PG probe and competitively hybridized with target, which led to G4-a and G4-b tending to form an intact intermolecular G-quadruplex, providing sites for MG intercalation, thus generating an activated "ON" fluorescence signal due to the restriction of intermolecular motion.

The consistently up-regulated expression of NLRP3 in severe asthma patients from mRNA microarray and ovalbumin-induced mouse model of asthma.
