Article Title: The Antihistamine Drugs Carbinoxamine Maleate and Chlorpheniramine Maleate Exhibit Potent Antiviral Activity Against a Broad Spectrum of Influenza Viruses

doi: 10.3389/fmicb.2018.02643

Figure Lengend Snippet: (A,B) Time of addition assay for analysis of mechanism of CAM and SCM against influenza A/shanghai/37T (2009H1N1) infection. MDCK cells cultured in DMEM supplemented with 10% FBS (Biowest, France), penicillin (100 U/ml), and streptomycin (10 μg/ml) at 37°C/5% CO 2 were infected with influenza A/shanghai/37T (2009H1N1) at 0.1 MOI in DMEM containing 2 μg/mL TPCK-Trypsin. CAM and SCM diluted in DMEM to give a final concentration of 20 μM were added to mixture of virus and cells at 0, 0.5, 1, 2, 4, and 12 h post infection. Inhibition activity of CAM and SCM was measured by CPE reduction assay using CCK-8, according to the manufacturer’s instruction. The data were presented as means ± SE of triplicate assays and the experiment was repeated at least twice.

Article Title: The MEK-ERK1/2 signaling pathway regulates hyaline cartilage formation and the redifferentiation of dedifferentiated chondrocytes in vitro

Figure Lengend Snippet: Cell morphology and gene and protein expression of Col2a1, Col1a1, Sox9, and MMP13 in chondrocytes stimulated with RS. A. Rat chondrocytes were cultured with DMEM plus 5% RS (5R) or DMEM plus 10% FBS (10F) for 24 h, and cell cultures were analyzed by microscopy. The chondrocytes dedifferentiated into fibroblastic chondrocytes after normal medium (DMEM plus 10% FBS, 10F) was replaced with DMEM containing 5% RS (5R). B. Col2a1, Col1a1 and MMP13 protein levels were analyzed by western blot. Col1a1 and MMP13 protein expression increased and Col2a1 protein expression decreased in the 5R group when compared to the 10F group. C. In situ expression of Col2a1, Col1a1, and Sox9 were detected in chondrocytes cultured with 5% RS or 10% FBS. The blue color indicates DAPI staining of nuclei. Red indicates Col2a1 expression and green indicates Col1a1 or Sox9 expression. Col1a1 and Sox9 expression increased and Col2a1 expression decreased in the 5R group when compared to the 10F group. D. Chondrocytes were cultured with RS or FBS for 24 h, mRNA was isolated from the chondrocytes, and expression of matrix degradation enzymes and collagen synthesis genes were analyzed by qRT-PCR. Data are expressed as the mean ± SD from three separate experiments. * P

Article Snippet: Chondrocytes were isolated from the articular cartilage of 24-hour-old Sprague-Dawley (SD) rats and dispersed in 0.1% collagenase type II (C6885, Sigma-Aldrich, Switzerland) for 3 h. Chondrocytes were collected and cultured in Dulbecco’s Modified Eagle’s Medium (DMEM, Biowest, France) supplemented with 10% FBS (Biowest, France) and 1% penicillin-streptomycin.

Figure Lengend Snippet: Analysis of GAG content and gene expression in chondrocytes cultured with the MEK inhibitor PD0325901. A. Chondrocytes were cultured in DMEM supplemented with 5% RS (5R), 10% FBS (10F), or 5% RS plus various PD0325901 concentrations for 24 h. Chondrocytes were stained with Safranin O (left), and the GAG content in the chondrocytes was measured using the DMB method (right). B. Gene expression of matrix degradation enzymes and collagen synthesis genes in chondrocytes was evaluated by qPCR after treatment with and without various concentrations of the MEK-ERK1/2 pathway inhibitor PD0325901. Data are expressed as the mean ± SD from three separate experiments. # P

doi: 10.1186/1471-2407-12-130

Figure Lengend Snippet: Release of NO from JS-K . (A) Generation of NO from JS-K in RPMI-1640 medium containing 10% fetal bovine serum was determined indirectly by photorimetric detection of nitrite according to Green et al. [ 31 ]. (B) Detection of nitrotyrosine by fluorescence microscopy in 22Rv1 cells: Generation of intracellular NO was detected indirectly by detection of nitrotyrosine (green). Cell nuclei were stained with DAPI. [A] untreated cells, [B] 2 μM JS-K neg , [C] 2 μM JS-K, [D] 200 μM DETA/NO.

doi: 10.1371/journal.pone.0183003

Figure Lengend Snippet: Crizotinib-induced apoptosis in Ba/F3 cells transformed by NPM-ALK. Ba/F3 cells were infected with an empty virus (-) and retrovirus expressing NPM-ALK or TEL-JAK2.

(B) Transduced Ba/F3 cells were incubated with RPMI containing 10% FBS in the absence of IL-3 for 2 days. Viable cell numbers at 24 hr and 48 hr were counted by the Trypan blue exclusion method. Values are the mean ± SD of three independent experiments. (C-F) Transduced Ba/F3 cells were incubated with RPMI containing 10% FBS in the presence of crizotinib (0.25, 0.5, 1 μM) and MMC (0.1, 1, 10 μg/mL) for 24 hr. (C) Cell viability was measured by the WST assay. Values are the mean ± S.D. of four independent experiments. (D) Cells were fixed, treated with propidium iodide, and subjected to a flow cytometric analysis. The percentages of cells in the sub-G1 phase were graphed. Values are the mean ± S.D. of four independent experiments. (E) To evaluate the apoptotic cell death, the chromatin DNA was isolated from cells and subjected to agarose gel electrophoresis. (F) Whole cell lysates were prepared and the phosphorylation of STAT3 and STAT5 was analyzed by immunoblotting. The relative phosphorylation level of STAT3 and STAT5 is shown in the graphs. Values are given as the mean ± SD of three independent experiments. *** P
