Serotonin 3 receptor signaling regulates 5-fluorouracil-mediated apoptosis indirectly via TNF-alpha production by enhancing serotonin release from enterochromaffin cells.

S. Mikawa et al.


Antagonists of the 5-hydroxytryptamine (serotonin) 3 receptor (5-HT3R) have anti-inflammatory and anti-apoptotic activities, but the detailed, underlying mechanisms are not well understood. We focused on anti-apoptotic activities via 5-HT3R signaling to clarify the underlying mechanisms. Mice were administered 5-fluorouracil (5-FU), which induced apoptosis in intestinal epithelial cells. Coadministration with 5-HT3R antagonists or agonists tended to decrease or increase the number of apoptotic cells, respectively. In serotonin 3A receptor (5-HT3AR) null (HTR3A-/-) mice, the number of apoptotic cells induced by 5-FU was decreased compared with that in wild-type (WT) mice. Bone marrow (BM) transplantation was performed to determine if BM-derived immune cells regulated 5-FU-induced apoptosis, but they were found to be unrelated to this process. Data from 5-HT3AR/enhanced green fluorescent protein reporter mice revealed that 50{\%} of enterochromaffin (EC) cells expressed 5-HT3AR, but the number of apoptotic cells induced by 5-FU in the intestinal crypt organoids of HTR3A-/- mice was not altered compared with WT mice. In contrast, plasma 5-HT concentrations in WT mice but not in HTR3A-/- mice administered 5-FU were increased significantly. In conclusion, 5-HT3R signaling may enhance 5-HT release, possibly from EC cells intravascularly, or paracrine, resulting in increases in plasma 5-HT concentration, which in turn, enhances apoptotic activities induced by 5-FU.-Mikawa, S., Kondo, M., Kaji, N., Mihara, T., Yoshitake, R., Nakagawa, T., Takamoto, M., Nishimura, R., Shimada, S., Ozaki, H., Hori, M.

Integrated Analysis of Mouse and Human Gastric Neoplasms Identifies Conserved microRNA Networks in Gastric Carcinogenesis.

Z. Chen et al.


BACKGROUND AIMS microRNAs (miRNAs) are small non-coding RNAs that bind to 3'UTR regions of mRNAs to promote their degradation or block their translation. Mice with disruption of the trefoil factor 1 gene (Tff1) develop gastric neoplasms. We studied these mice to identify conserved miRNA networks involved in gastric carcinogenesis. METHODS We performed next-generation miRNA sequencing analysis of normal gastric tissues (based on histology) from subjects without evidence of gastric neoplasm from patients (n=64) and TFF1-knockout mice (n=22). We validated our findings using 270 normal gastric tissues (including 61 samples from patients without evidence of neoplastic lesions) and 234 gastric tumor tissues from 3 separate cohorts of patients and from mice. We performed molecular and functional assays using cell lines (MKN28, MKN45, STKM2, and AGS cells), gastric organoids, and mice with xenograft tumors. RESULTS We identified 117 miRNAs that were significantly deregulated in mouse and human gastric tumor tissues, compared with non-tumor tissues. We validated changes in levels of 6 miRNAs by quantitative real-time PCR analyses of neoplastic gastric tissues from mice (n=39) and 3 independent cohorts patients (332 patients total). We found levels of MIR135B-5p, MIR196B-5p, and MIR92A-5p to be increased in tumor tissues whereas levels of MIR143-3p, MIR204-5p, and MIR133-3p were decreased in tumor tissues. Levels of MIR143-3p were reduced not only in gastric cancer tissues, but also in normal tissues adjacent to tumors in humans and low-grade dysplasia in mice. Transgenic expression of MIR143-3p in gastric cancer cell lines reduced their proliferation and restored their sensitivity to cisplatin. AGS cells with stable transgenic expression of MIR143-3p grew more slowly as xenograft tumors in mice than control AGS cells; tumor growth from AGS cells that expressed MIR143-3p, but not control cells, was sensitive to cisplatin. We identified and validated bromodomain containing 2 (BRD2) as a direct target of MIR143-3p; increased levels of BRD2 in gastric tumors associated with shorter survival times of patients. CONCLUSIONS In an analysis of miRNA profiles of gastric tumors from mice and human patients, we identified a conserved signature associated with early stages of gastric tumorigenesis. Strategies to restore MIR143-3p or inhibit BRD2 might be developed for treatment of gastric cancer.

Neonatal intestinal organoids as an ex vivo approach to study early intestinal epithelial disorders.

B. Li et al.


BACKGROUND Adult intestinal organoids have been used to study ex vivo intestinal injury in adulthood. However, the neonatal intestinal epithelium has many unique features that are different from adult mature intestine. Establishing a neonatal ex vivo organoid model is essential to study the epithelial physiology in early postnatal development and to investigate derangements associated with disease processes during the neonatal period like necrotizing enterocolitis (NEC). METHODS Fresh and frozen terminal ileum was harvested from mice pups on postnatal day 9. Crypts were isolated and organoids were cultured. Organoids were exposed to hypoxia and lipopolysaccharide (LPS) for 48 h to induce epithelial injury. Inflammatory cytokines and tight junction proteins were evaluated. RESULTS Robust intestinal organoids can be formed from both fresh and frozen intestinal tissue of neonatal mice pups. Hypoxia and LPS administration induced intestinal inflammation and disrupted tight junctions in these neonatal intestinal organoids. CONCLUSIONS We have established a novel method to grow organoids from neonatal intestine. We demonstrated that these organoids respond to the injury occurring during neonatal intestinal diseases such as NEC by increasing the organoid inflammation and by disrupting the organoid barrier function. Organoids provide an ex vivo platform to study intestinal physiology and pathology during the neonatal period.

Human Organoids Share Structural and Genetic Features with Primary Pancreatic Adenocarcinoma Tumors.

I. Romero-Calvo et al.


Patient-derived pancreatic ductal adenocarcinoma (PDAC) organoid systems show great promise for understanding the biological underpinnings of disease and advancing therapeutic precision medicine. Despite the increased use of organoids, the fidelity of molecular features, genetic heterogeneity, and drug response to the tumor of origin remain important unanswered questions limiting their utility. To address this gap in knowledge, primary tumor- and patient-derived xenograft (PDX)-derived organoids, and 2D cultures for in-depth genomic and histopathologic comparisons with the primary tumor were created. Histopathologic features and PDAC representative protein markers (e.g., claudin 4 and CA19-9) showed strong concordance. DNA- and RNA-sequencing (RNAseq) of single organoids revealed patient-specific genomic and transcriptomic consistency. Single-cell RNAseq demonstrated that organoids are primarily a clonal population. In drug response assays, organoids displayed patient-specific sensitivities. In addition, the in vivo PDX response to FOLFIRINOX and gemcitabine/abraxane treatments were examined, which was recapitulated in vitro with organoids. This study has demonstrated that organoids are potentially invaluable for precision medicine as well as preclinical drug treatment studies because they maintain distinct patient phenotypes and respond differently to drug combinations and dosage. IMPLICATIONS: The patient-specific molecular and histopathologic fidelity of organoids indicate that they can be used to understand the etiology of the patient's tumor and the differential response to therapies and suggests utility for predicting drug responses.

Developing a 3D intestinal epithelium model for livestock species.

H. Derricott et al.


The in vitro 3D culture of intestinal epithelium is a valuable resource in the study of its function. Organoid culture exploits stem cells' ability to regenerate and produce differentiated epithelium. Intestinal organoid models from rodent or human tissue are widely available whereas large animal models are not. Livestock enteric and zoonotic diseases elicit significant morbidity and mortality in animal and human populations. Therefore, livestock species-specific models may offer novel insights into host-pathogen interactions and disease responses. Bovine and porcine jejunum were obtained from an abattoir and their intestinal crypts isolated, suspended in Matrigel, cultured, cryopreserved and resuscitated. 'Rounding' of crypts occurred followed by budding and then enlargement of the organoids. Epithelial cells were characterised using immunofluorescent staining and confocal microscopy. Organoids were successfully infected with Toxoplasma gondii or Salmonella typhimurium. This 3D organoid model offers a long-term, renewable resource for investigating species-specific intestinal infections with a variety of pathogens.
