Article Title: Caspase-9b interacts directly with cIAP1 to drive agonist-independent activation of NF-κB and lung tumorigenesis

doi: 10.1158/0008-5472.CAN-15-2512

Figure Lengend Snippet: (A–D) A549 cells were transfected with the indicated siRNAs,48hr. HBECs were transfected with adenovirus (Ad) control (Con) or expressing C9b,24hr. RNA was isolated and analyzed by RNAseq. (A) Network computationally generated on the basis of IPA knowledge memory indicated a high relevance to the NF-κB pathway. Red, increased expression; green, reduced expression; higher color intensity indicates higher difference in expression level. Cell localization of NF-κB-related factors is indicated (Fig. S1, larger legend). (B) Total protein was subjected to SDS-PAGE/immunoblotting. (C) The network for A549 cells comprises 77 NF-κB-related genes significantly different between control siRNAs and C9b siRNA samples. The network for HBECs comprises 133 NF-κB-related genes significantly different between AdCon and AdC9b samples. There are 15 overlapping genes; (Table S2). (D) Heatmap showing hierarchical clustering of 7 overlapping NF-κB genes that expression is contrastingly affected by C9b siRNA (A549) versus up-regulation of C9b (HBEC); red=increased expression; green=reduced expression (Table S3). Results were repeated on 2 separate occasions. (E) Total RNA from C9b-downregulated A549 cells was subjected to RT-qPCR for 7 overlapping NF-κB genes in (D). Data in E are shown as mean ± SD; n=6: one-way ANOVA followed by a Tukey’s HSD test (##p<0.01, **p<0.001); C9b-siRNA sample was compared to each control siRNA sample. (F) RT-qPCR for C9b and 5 NF-κB target genes was performed on lung tissues of 22 NSCLC patients. Values=means of triplicates; each dot represents a patient; Pearson correlation coefficient (r value) and corresponding significance level (p value) are indicated (Fig.S2). (G) LCM images of pre-LCM slide, post-LCM slide after isolating tumors and post-LCM cap view of purified tumor epithelium; tumor and normal epithelial cells are indicated in pre-LCM slides. (H) RT-qPCR for C9b and BIRC5 was performed from RNA prepared from LCM purified epithelium in (G); data are shown as means ± SD (n=3). (I) RT-qPCR for C9a, C9b or BIRC5 was performed with RNA purified from the NSCLC cell lines in Table S3.; Values=means of triplicates; each dot represents a NSCLC cell line.

doi: 10.3390/cancers17223721

Figure Lengend Snippet: Drug screening and validation of Niclosamide using CCA cell lines and primary biliary epithelial cells. ( A ) A library of 104 off-patent drugs was screened using the CCLP CCA cell line. CCLP cells were plated at 1 × 10 4 cells per well in a 96 well plate and treated with each drug at its clinically relevant peak serum concentration for 96 h. Cell viability was then determined using an MTT assay and normalised to cells treated with the corresponding vehicle control for each drug. N = 3 biological repeats with a paired, two-tailed T-test followed by Benjamini–Hochberg multiple corrections. The inhibition of viability (%) is plotted against the reciprocal of the p value for each drug and Niclosamide is labelled. ( B – E ) Niclosamide dose–response curves for CCA cell lines (CCLP, RBE, and KKU-M055) and primary biliary epithelial cells (BECs) plated as in ( A ) and treated with Niclosamide [10 nM–100 μM] or vehicle control for 72 h. Cell viability was measured using an MTT assay and normalised to vehicle control. N = 3 biological repeats each performed in triplicate. Error bars represent SEM. When error bars cannot be seen they are smaller than the symbols. ( F ) The graph shows the relative EC50 values for each cell type calculated using GraphPad Prism. Error bars represent SEM (* = p < 0.05 unpaired t -test). The inserted Western blot shows PRH levels in the CCA cell lines prior to treatment and with β-actin as a loading control.

( D ) CCLP cells and BECs were grown as spheroids for 5 days before treatment with 0.5 μM Niclosamide, 1 μM Palbociclib, or both drugs in combination for a further 72 h.

Article Title: Corylin Ameliorates LPS-Induced Acute Lung Injury via Suppressing the MAPKs and IL-6/STAT3 Signaling Pathways

doi: 10.3390/ph14101046

Figure Lengend Snippet: Anti-inflammatory effect of corylin on LPS-induced ALI. The experimental results demonstrated that corylin attenuated the overproduction of IL-6 in LPS-activated human bronchial epithelial cells. In intratracheal LPS-induced ALI mice, corylin attenuated tissue damages, suppressed inflammatory cell infiltration, and decreased secretion of IL-6 and TNF-α in the BALF and serum; moreover, it further inhibited the expression of phosphorylation of mitogen-activated protein kinases (MAPKs), including the expression of p-JNK/JNK, p-ERK/ERK, p-p38/p38, and repressed the activation of signal transducer and activator of transcription 3 (STAT3) in lung. Taken together, our results are the first to demonstrate the anti-inflammatory effects of corylin on LPS-induced ALI and suggest corylin has significant potential as a novel therapeutic agent for ALI.
