LF was slightly better than VI for advanced lesions on occlusal surfaces of permanent teeth in the clinical setting and for all lesions on proximal surfaces of permanent teeth in the laboratory setting. Still, LF was worse than VI for advanced occlusal lesions in permanent teeth in the laboratory setting. Although LF showed slightly better performance than VI with advanced lesions, the latter had significantly higher specificity than other methods in all settings. Visual caries detection alone is adequate for most patients in daily clinical practice regardless of tooth type or surface.

Lysophosphatidic acid receptor 1 (LPA1) is a receptor for bioactive lysophospholipid, LPA. LPA/LPA1-mediated signaling contributes to inflammatory and fibrotic responses in lung diseases; thus understanding regulation of LPA1 stability is important for modulating LPA/LPA1 signaling. Our previous study has shown that LPA1 is degraded in the Nedd4 like (Nedd4L) E3 ubiquitin ligase-mediated ubiquitin-proteasome system. In the current study, we attempt to identify a peptide that stabilizes LPA1 through disrupting LPA1 association with Nedd4L. LPA treatment induces both endogenous and overexpressed LPA1 degradation, which is attenuated by a proteasome inhibitor, suggesting that LPA1 is degraded in the proteasome. LPA increases phosphorylation of extracellular signal-regulated kinase 1/2 (Erk1/2) and I-κB kinase in lung epithelial cells, and this effect is promoted by overexpression of a peptide (P1) that mimics C-termin
