Endoplasmic reticulum stress and IRE-1 signaling cause apoptosis in colon cancer cells in response to andrographolide treatment.

Banerjee A et al.


The plant metabolite andrographolide induces cell cycle arrest and apoptosis in cancer cells. The mechanism(s) by which andrographolide induces apoptosis however, have not been elucidated. The present study was performed to determine the molecular events that promote apoptosis in andrographolide treated cells using T84, HCT116 and COLO 205 colon cancer cell lines. Andrographolide was determined to limit colony formation and Ki67 expression, alter nuclear morphology, increase cytoplasmic histone-associated-DNA-fragments, and increase cleaved caspase-3 levels. Andrographolide also induced significantly higher expression of endoplasmic reticulum (ER) stress proteins GRP-78 and IRE-1 by 48 h but not PERK or ATF6. Apoptosis signaling molecules BAX, spliced XBP-1 and CHOP were also significantly increased. Moreover, chemical inhibition of ER stress or IRE-1 depletion with siRNA in andrographolide treated cells significantly limited expression of IRE-1 and CHOP as determined by immunofluorescence staining, real time PCR, or immunobloting. This was accompanied by a decreased BAX/Bcl-2 ratio. Andrographolide significantly promotes cancer cell death compared to normal cells. These data demonstrate that andrographolide associated ER stress contributes to apoptosis through the activation of a pro-apoptotic GRP-78/IRE-1/XBP-1/CHOP signaling pathway.

Olfactomedin 4 deletion induces colon adenocarcinoma in Apc(Min/+) mice.

Liu W et al.


Colon carcinogenesis is a multiple-step process involving the accumulation of a series of genetic and epigenetic alterations. The most commonly initiating event of intestinal carcinogenesis is mutation of the adenomatous polyposis coli (APC) gene, which leads to activation of the Wnt/$-catenin pathway. Olfactomedin 4 (OLFM4) has emerged as an intestinal stem-cell marker, but its biological function in the intestine remains to be determined. Here we show that Olfm4 deletion induced colon adenocarcinoma in the distal colon of Apc(Min/+) mice. Mechanistically, we found that OLFM4 is a target gene of the Wnt/$-catenin pathway and can downregulate $-catenin signaling by competing with Wnt ligands for binding to Frizzled receptors, as well as by inhibition of the Akt-GSK-3$ (Akt-glycogen synthase kinase-3$) pathway. We have shown that both Wnt and nuclear factor-$B (NF-$B) signaling were boosted in tumor tissues of Apc Olfm4 double-mutant mice. These data establish OLFM4 as a critical negative regulator of the Wnt/$-catenin and NF-$B pathways that inhibits colon-cancer development initiated by APC mutation. In addition, Olfm4 deletion significantly enhanced intestinal-crypt proliferation and inflammation induced by azoxymethane/dextran sodium sulfate. Thus, OLFM4 has an important role in the regulation of intestinal inflammation and tumorigenesis, and could be a potential therapeutic target for intestinal malignant tumors. Unlike the human colonic epithelium, the mouse colonic epithelium does not express OLFM4, but nevertheless, systemic OLFM4 deletion promotes colon tumorigenesis and that loss from mucosal neutrophils may have a role to play.Oncogene advance online publication, 14 March 2016; doi:10.1038/onc.2016.58.

An LGG-derived protein promotes IgA production through upregulation of APRIL expression in intestinal epithelial cells.

Wang Y et al.


p40, a Lactobacillus rhamnosus GG (LGG)-derived protein, transactivates epidermal growth factor receptor (EGFR) in intestinal epithelial cells, leading to amelioration of intestinal injury and inflammation. To elucidate mechanisms by which p40 regulates mucosal immunity to prevent inflammation, this study aimed to determine the effects and mechanisms of p40 on regulation of a proliferation-inducing ligand (APRIL) expression in intestinal epithelial cells for promoting immunoglobulin A (IgA) production. p40 upregulated April gene expression and protein production in mouse small intestine epithelial (MSIE) cells, which were inhibited by blocking EGFR expression and kinase activity. Enteroids from Egfr(fl/fl), but not Egfr(fl/fl)-Vil-Cre mice with EGFR specifically deleted in intestinal epithelial cells, exhibited increased April gene expression by p40 treatment. p40-conditioned media from MSIE cells increased B-cell class switching to IgA(+) cells and IgA production, which was suppressed by APRIL receptor-neutralizing antibodies. Treatment of B cells with p40 did not show any effects on IgA production. p40 treatment increased April gene expression and protein production in small intestinal epithelial cells, fecal IgA levels, IgA(+)B220(+), IgA(+)CD19(+), and IgA(+) plasma cells in lamina propria of Egfr(fl/fl), but not of Egfr(fl/fl)-Vil-Cre, mice. Thus p40 upregulates EGFR-dependent APRIL production in intestinal epithelial cells, which may contribute to promoting IgA production.Mucosal Immunology advance online publication, 29 June 2016; doi:10.1038/mi.2016.57.

Glial-cell-derived neuroregulators control type 3 innate lymphoid cells and gut defence.

Ibiza S et al.


Group 3 innate lymphoid cells (ILC3) are major regulators of inflammation and infection at mucosal barriers. ILC3 development is thought to be programmed, but how ILC3 perceive, integrate and respond to local environmental signals remains unclear. Here we show that ILC3 in mice sense their environment and control gut defence as part of a glial–ILC3–epithelial cell unit orchestrated by neurotrophic factors. We found that enteric ILC3 express the neuroregulatory receptor RET. ILC3-autonomous Ret ablation led to decreased innate interleukin-22 (IL-22), impaired epithelial reactivity, dysbiosis and increased susceptibility to bowel inflammation and infection. Neurotrophic factors directly controlled innate Il22 downstream of the p38 MAPK/ERK-AKT cascade and STAT3 activation. Notably, ILC3 were adjacent to neurotrophic-factor-expressing glial cells that exhibited stellate-shaped projections into ILC3 aggregates. Glial cells sensed microenvironmental cues in a MYD88-dependent manner to control neurotrophic factors and innate IL-22. Accordingly, glial-intrinsic Myd88 deletion led to impaired production of ILC3-derived IL-22 and a pronounced propensity towards gut inflammation and infection. Our work sheds light on a novel multi-tissue defence unit, revealing that glial cells are central hubs of neuron and innate immune regulation by neurotrophic factor signals.

Hydroxytyrosol supplementation modulates the expression of miRNAs in rodents and in humans.

Tomé-Carneiro J et al.


Dietary microRNAs (miRNAs) modulation could be important for health and wellbeing. Part of the healthful activities of polyphenols might be due to a modulation of miRNAs' expression. Among the most biologically active polyphenols, hydroxytyrosol (HT) has never been studied for its actions on miRNAs. We investigated whether HT could modulate the expression of miRNAs in vivo. We performed an unbiased intestinal miRNA screening in mice supplemented (for 8 weeks) with nutritionally relevant amounts of HT. HT modulated the expression of several miRNAs. Analysis of other tissues revealed consistent HT-induced modulation of only few miRNAs. Also, HT administration increased triglycerides levels. Acute treatment with HT and in vitro experiments provided mechanistic insights. The HT-induced expression of one miRNA was confirmed in healthy volunteers supplemented with HT in a randomized, double-blind and placebo-controlled trial. HT consumption affects specific miRNAs' expression in rodents and humans. Our findings suggest that the modulation of miRNAs' action through HT consumption might partially explain its healthful activities and might be pharmanutritionally exploited in current therapies targeting endogenous miRNAs. However, the effects of HT on triglycerides warrant further investigations.
