Characteristics of minerals in vesicles produced by human osteoblasts hFOB 1.19 and osteosarcoma Saos-2 cells stimulated for mineralization.[Pubmed:28380345]

J Inorg Biochem. 2017 Jun;171:100-107.

Bone cells control initial steps of mineralization by producing extracellular matrix (ECM) proteins and releasing vesicles that trigger apatite nucleation. Using transmission electron microscopy with energy dispersive X-ray microanalysis (TEM-EDX) we compared the quality of minerals in vesicles produced by two distinct human cell lines: fetal osteoblastic hFOB 1.19 and osteosarcoma Saos-2. Both cell lines, subjected to osteogenic medium with ascorbic acid (AA) and beta-glycerophosphate (beta-GP), undergo the entire osteoblastic differentiation program from proliferation to mineralization, produce the ECM and spontaneously release vesicles. We observed that Saos-2 cells mineralized better than hFOB 1.19, as probed by Alizarin Red-S (AR-S) staining, tissue nonspecific alkaline phosphatase (TNAP) activity and by analyzing the composition of minerals in vesicles. Vesicles released from Saos-2 cells contained and were surrounded by more minerals than vesicles released from hFOB 1.19. In addition, there were more F and Cl substituted apatites in vesicles from hFOB 1.19 than in those from Saos-2 cells as determined by ion ratios. Saos-2 and h-FOB 1.19 cells revealed distinct mineralization profiles, indicating that the process of mineralization may proceed differently in various types of cells. Our findings suggest that TNAP activity is correlated with the relative proportions of mineral-filled vesicles and mineral-surrounded vesicles. The origin of vesicles and their properties predetermine the onset of mineralization at the cellular level.

Is MPP a good prognostic factor in stage III lung adenocarcinoma with EGFR exon 19 mutation?[Pubmed:28380449]

Oncotarget. 2017 Jun 20;8(25):40594-40605.

Epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein encoded by a gene located in the short arm of chromosome 7. This study aimed to investigate the clinicopathologic characteristics of classic EGFR exon mutation in Chinese patients with TMN stage III lung adenocarcinoma who received radical surgery. A total of 1,801 lung adenocarcinomas were analyzed for mutations in EGFR; 35% exhibited mutation of classic EGFR exons. Clinical and pathologic characteristics of patients with EGFR exon 19 mutation were compared with those who harbored EGFR exon 21 mutation. Patients with EGFR exon 19 mutation had a higher overall survival (OS, p=0.023) than those harboring EGFR exon 21 mutation. Our results demonstrated that patients with a micropapillary pattern (MPP) pathologic type in EGFR exon 19 mutation had a higher OS (p=0.022), and patients with exon 19 mutation were more sensitive to EGFR-tyrosine kinase inhibitors (p=0.032). The results of the current study can be used in decision-making regarding the treatment of patients with classic EGFR exon mutations.

Chenodeoxycholic acid stimulated fibroblast growth factor 19 response - a potential biochemical test for bile acid diarrhoea.[Pubmed:28378364]

Aliment Pharmacol Ther. 2017 Jun;45(11):1433-1442.

BACKGROUND: Bile acid diarrhoea is underdiagnosed and better diagnostic tests are needed. Fasting serum fibroblast growth factor-19 (FGF19) has insufficient diagnostic value, but this may be improved by stimulation. AIM: To explore if an impaired FGF19 response identifies primary bile acid diarrhoea. METHODS: Eight patients with primary bile acid diarrhoea and eight healthy volunteers ingested (i) a meal plus 1250 mg chenodeoxycholic acid (CDCA), (ii) 1250 mg CDCA or (iii) the meal. Blood was sampled at fasting and repeatedly after stimulation. We analysed FGF19 by enzyme-linked immunosorbent assay and bile acids including 7alpha-hydroxy-4-cholesten-3-one by liquid chromatography-tandem mass spectrometry. RESULTS: Stimulation with the meal plus CDCA increased median FGF19 in healthy volunteers from fasting 62 pg/mL [interquartile range (IQR): 41-138] to 99 pg/mL (IQR: 67-147; P = 0.012) after 90 min and peaked after 150 min at 313 pg/mL (IQR: 54-512). This response was impaired in primary bile acid diarrhoea patients [fasting 56 pg/mL (IQR: 42-79); 90 min: 48 pg/mL [IQR: 37-63); 150 min: 57 pg/mL (48-198)]. Receiver operating characteristics (ROCAUC ) for fasting FGF19 was 0.55 (P = 0.75) and at 90 min 0.84 (P = 0.02). The difference in FGF19 from fasting to 90 min after the meal plus CDCA separated the groups (ROCAUC 1.0; P = 0.001). 7alpha-hydroxy-4-cholesten-3-one was elevated in primary bile acid diarrhoea (P = 0.038) and not significantly affected by stimulation. CONCLUSIONS: The FGF19 response following chenodeoxycholic acid plus meal is impaired in primary bile acid diarrhoea. This may provide a biochemical diagnostic test.

Identification of a chemical probe for NAADP by virtual screening.[Pubmed:19234453]

Nat Chem Biol. 2009 Apr;5(4):220-6.

Research into the biological role of the Ca(2+)-releasing second messenger NAADP (nicotinic acid adenine dinucleotide phosphate) has been hampered by a lack of chemical probes. To find new chemical probes for exploring NAADP signaling, we turned to virtual screening, which can evaluate millions of molecules rapidly and inexpensively. We used NAADP as the query ligand to screen the chemical library ZINC for compounds with similar three-dimensional shape and electrostatic properties. We tested the top-ranking hits in a sea urchin egg bioassay and found that one hit, Ned-19, blocks NAADP signaling at nanomolar concentrations. In intact cells, Ned-19 blocked NAADP signaling and fluorescently labeled NAADP receptors. Moreover, we show the utility of Ned-19 as a chemical probe by using it to demonstrate that NAADP is a key causal link between glucose sensing and Ca(2+) increases in mouse pancreatic beta cells.
