Abstract
BACKGROUND Compared to humans, colorectal polyps are relatively rare in dogs. Epidemiological and prognostic data remain accordingly sparse, although they could help veterinary clinicians in the management of these cases. OBJECTIVES To report the epidemiological data of dogs with colorectal polyps and identify factors associated with recurrence and survival. ANIMALS Fifty-eight client-owned dogs with colorectal polyps admitted to 7 veterinary hospitals (53 dogs from France, 5 dogs from Spain, and 4 dogs from Portugal) were included. METHODS Retrospective multicentric cohort study. Medical records and long-term outcome of the dogs were reviewed. When available, histological samples were reassessed by 2 board-certified pathologists according to the revised Vienna classification (RVC). RESULTS The West Highland White Terrier (WHWT) breed was significantly associated with the presence of colorectal polyps (OR: 20; 95% CI: 7.5-52; P < .001). The overall median time to recurrence was not reached after 2000 days. The overall estimated median survival time was 1640 days. WHWT breed and larger polyps were significantly associated with a shorter time of polyp recurrence after surgical removal (respectively, P = .05 and P = .01). CONCLUSIONS AND CLINICAL IMPORTANCE The probability of recurrence of colorectal polyps in dogs is low, but increased in WHWTs and larger polyps, which might benefit from routine screening after removal. No effective predictors of polyp recurrence and survival were identified using the RVC.

Abstract
Inflammatory colorectal polyp (ICRP) in miniature dachshunds (MDs) is a chronic inflammatory bowel disease (IBD) characterized by granulomatous inflammation that consists of neutrophil infiltration and goblet cell hyperplasia in the colon. Recently, we identified five MD-associated single-nucleotide polymorphisms (SNPs), namely PLG, TCOF1, TG, COL9A2, and COL4A4, by whole-exome sequencing. Here, we investigated whether TG c.4567C>T (p.R1523W) is associated with the ICRP pathology. We found that the frequency of the T/T SNP risk allele was significantly increased in MDs with ICRP. In vitro experiments showed that TG expression in non-immune cells was increased by inducing the IL-6 amplifier with IL-6 and TNF-α. On the other hand, a deficiency of TG suppressed the IL-6 amplifier. Moreover, recombinant TG treatment enhanced the activation of the IL-6 amplifier, suggesting that TG is both a positive regulator and a target of the IL-6 amplifier. We also found that TG expression together with two NF-κB targets, IL6 and CCL2, was increased in colon samples isolated from MDs with the T/T risk allele compared to those with the C/C non-risk allele, but serum TG was not increased. Cumulatively, these results suggest that the T/T SNP is an expression quantitative trait locus (eQTL) of TG mRNA in the colon, and local TG expression triggered by this SNP increases the risk of ICRP in MDs via the IL-6 amplifier. Therefore, TG c.4567C>T is a diagnostic target for ICRP in MDs, and TG-mediated IL-6 amplifier activation in the colon is a possible therapeutic target for ICRP.

Abstract
Angiogenesis plays an important role in the proliferation and metastasis mechanisms of malignant tumors. Vascular endothelial growth factor (VEGF), a group of cytokines that contribute to
angiogenesis and vasculogenesis. This study aimed to investigate the serum VEGF-A concentrations in dogs with various proliferative diseases. A total of 202 dogs that were
histopathologically diagnosed with proliferative diseases were included in the study. Serum VEGF-A concentrations were measured using enzyme-linked immunosorbent assay. Median serum VEGF-A
concentrations in dogs were as follows: healthy dogs, 4 pg/ml [0–21 pg/ml]; hepatocellular carcinoma, 30 pg/ml [0–158 pg/ml, P=<0.001]; hepatocellular adenoma, 32 pg/ml
[0–49 pg/ml, P=0.003]; hepatic nodular hyperplasia, 18 pg/ml [0–51 pg/ml, P=0.595]; adrenal pheochromocytoma, 32 pg/ml [0–187 pg/ml,
P=<0.001]; adrenocortical carcinoma, 32 pg/ml [3–161 pg/ml, P=0.002]; adrenocortical adenoma, 27 pg/ml [0–106 pg/ml, P=0.005];
colorectal adenocarcinoma, 36 pg/ml [0–75 pg/ml, P=0.002]; colorectal adenoma, 43 pg/ml [0–48 pg/ml, P=0.144]; inflammatory colorectal polyps, 37 pg/ml
[0–111 pg/ml, P=<0.001]; pulmonary adenocarcinoma, 35 pg/ml [4–107 pg/ml, P=0.002]; pulmonary histiocytic sarcoma, 35 pg/ml [0–131 pg/ml,
P=0.016]; and follicular thyroid carcinoma, 35 pg/ml [0–106 pg/ml, P=0.009]. The serum VEGF-A concentrations were significantly higher in dogs with
neoplastic lesions compared to healthy dogs, except for colorectal adenoma. High serum VEGF-A concentrations were observed in dogs with proliferative diseases. The present study suggests
that angiogenesis-inhibiting therapy, which targets VEGF-A, may be useful for canine neoplastic diseases.

Abstract
Hyperplastic goblet cells and abundant mucus are significant characteristics of
inflammatory colorectal polyps (ICRPs) in miniature dachshunds. In this study, selected
mucin gene expressions and goblet cell proportions were evaluated in miniature dachshunds
with ICRPs and in healthy dogs. Mucin 2 (MUC2) gene
expression was not significantly different among the groups, whereas mucin
5AC (MUC5AC) gene expression was significantly higher in the
polypoid lesions than in healthy colonic mucosa. Although the percentage of goblet cells
in the upper crypt regions did not significantly differ between the groups, that in the
lower crypt regions was significantly decreased in polypoid lesions. In conclusion,
increased MUC5AC gene expression and goblet cell proportion changes may
be associated with the pathogenesis of ICRPs.

Abstract
Background Inflammation is believed to influence human colorectal carcinogenesis and may have an impact on prognosis and survival. The mucosal immunophenotype in dogs with colorectal cancer is poorly described. The aim of this study was to investigate whether the density, distribution and grade of tumor-infiltrating immune cells (TIIs) are different in normal colonic tissue vs benign stages (adenomas) and malignant stages (adenocarcinomas) of canine colorectal carcinogenesis, and thus, whether they can be considered as prognostic factors in dogs. This retrospective case-control study was performed on formalin-fixed, paraffin-embedded tissue samples from dogs with histologically confirmed colorectal adenoma (n = 18) and adenocarcinoma (n = 13) collected from archived samples. The samples had been collected by colonoscopy, surgery or during postmortem examination. Healthy colonic tissue obtained post mortem from dogs euthanized for reasons not involving the gastrointestinal tract served as control tissue (n = 9). Results The tumor samples had significantly lower numbers of CD3+ T-cells in the epithelium compared to controls (adenocarcinoma vs control, Kruskal-Wallis test, p = 0.0004, and adenoma vs control, p = 0.002). Adenomas had a significantly lower number of CD18+ cells in the lamina propria, compared to control samples (Kruskal-Wallis test, p = 0.008). Colonic samples from control dogs had uniform staining of β-catenin along the cell membrane of epithelial cells. Compared to normal colonic cells, the expression levels of cytoplasmic β-catenin were significantly higher in adenomas and adenocarcinomas (adenoma vs control Kruskal-Wallis test, p = 0.004, and adenocarcinoma vs control, p = 0.002). None of the control samples showed positive staining of β-catenin in the nucleus of colonic cells. In contrast, adenocarcinomas and adenomas showed moderate to strong staining of the cell nucleus. The nuclear β-catenin expression (signal strength and distribution) was significantly higher in adenomas compared to adenocarcinomas (Kruskal-Wallis test, p < 0.05). Conclusions β-catenin and Ki67 were not useful markers for demonstrating tumor progression from adenomas to adenocarcinomas. The lower presence of CD18 and CD3+ cells in colorectal tumors compared to controls indicates a reduced presence of histiocytes and T-cells, which may have implications for the pathogenesis and progression of colorectal cancer in dogs.

Abstract
There has been an increase in the number of Jack Russell Terriers (JRTs) diagnosed with
adenomas and adenocarcinomas of the gastrointestinal tract in Japan. This study
retrospectively investigated the clinical and histopathological features and prognosis of
adenocarcinomas arising in the gastrointestinal tract in JRT dogs. Seven JRTs and 39 dogs
of other breeds diagnosed with gastrointestinal adenocarcinoma were included in the study.
The most common sites of gastrointestinal adenocarcinoma in JRTs were the pylorus and
rectum. On histopathological examination, these adenocarcinomas showed a papillary or
tubular growth pattern, and the lesions were confined within the mucosal epithelium and
poorly invasive. Among all dogs with gastric adenocarcinoma, the median survival time
(MST) for five of the JRTs could not be determined because more than half of the cases
remained alive, while the MST for nine non-JRT dogs was 34 days. Among all dogs with
adenocarcinoma in the large intestine, the MST for three of the JRTs could not be
determined, while the MST for nine non-JRT dogs was 1,973 days. The difference in MST
between JRT and non-JRT dogs with gastric adenocarcinoma was significant
(P=0.0220). Since gastrointestinal adenocarcinomas in JRTs show
distinct characteristics with respect to their clinical features, treatment course, and
prognosis, a different surgical and medical treatment plan should be considered compared
to the management of gastrointestinal adenocarcinomas in other dog breeds.

Abstract
Inflammatory colorectal polyps (ICRPs) in miniature dachshunds (MDs) are speculated to be a breed-specific inflammatory bowel disease (IBD). Leucine-rich alpha-2 glycoprotein (LRG) has been identified as a novel biomarker of human IBD. The aim of this study was to examine LRG gene expression in the polypoid lesions of ICRPs. Polypoid lesion specimens were collected from 24 MDs with ICRPs. Nonpolypoid colonic mucosa was collected from 18 MDs with ICRPs and 10 controls. The gene expression of LRG, interleukin (IL)-1β, IL-6, tumor necrosis factor-α, and IL-22 was examined. The expression of LRG gene was significantly increased in the polypoid lesions of ICRPs and correlated with that of the four cytokines. In conclusion, the LRG gene was expressed within the polypoid lesions of ICRPs and might be associated with local cytokine expression.

Abstract
OBJECTIVE To investigate the activities of gelatinases (matrix metalloproteinase [MMP]-2 and MMP-9) and serine proteases in the colorectal mucosa of Miniature Dachshunds (MDs) with inflammatory colorectal polyps (ICRPs). ANIMALS 15 MDs with ICRPs and 5 dogs with non-ICRP-related large bowel diarrhea (controls). PROCEDURES Zymographic methods were used to evaluate the activities of MMP-2, MMP-9, latent forms of MMP-2 and MMP-9 (pro-MMP-2 and pro-MMP-9), and serine proteases in inflamed and noninflamed tissue samples from MDs with ICRPs and in noninflamed tissue samples from control dogs. The associations of serine protease activities with MMP-2 or MMP-9 activity were also analyzed. RESULTS Activities of pro-MMP-2 and pro-MMP-9 were detected in most tissue samples, regardless of the tissue type, whereas activities of MMP-2 and MMP-9 were not detected in control tissue samples. In the inflamed tissue samples from MDs with ICRPs, the activities of MMP-2, pro-MMP-9, and MMP-9 were significantly higher than those in the noninflamed tissue samples from those dogs. Serine protease activities were significantly higher in the inflamed and noninflamed tissue samples from MDs with ICRP, compared with findings for control tissue samples. A weak correlation was detected between serine protease activities and MMP-9 activity. CONCLUSIONS AND CLINICAL RELEVANCE Study results suggested that gelatinase and serine protease activities are upregulated in the colorectal mucosa of MDs with ICRPs, possibly contributing to the pathogenesis of this disease through the functions of these enzymes in degradation of extracellular matrix and promotion of inflammatory cell migration and inflammatory responses.

Abstract
Inflammatory colorectal polyps (ICRPs) are frequently observed in miniature dachshunds in Japan and treated by prednisolone and immunosuppressive drugs such as cyclosporine and leflunomide. The purpose of this retrospective study was to compare the treatment efficacy, such as response rate, response interval, recurrence rate, and adverse events between cyclosporine and leflunomide. While the response rates were significantly higher in dogs treated with leflunomide, no significant differences were observed in the response interval or recurrence rate. Two of the 11 dogs treated with leflunomide showed hematological or gastrointestinal adverse events, while no dog treated with cyclosporine showed any adverse events. A case-controlled prospective study to compare the treatment efficacy of leflunomide with that of cyclosporine should be conducted.

Abstract
The present study evaluated the histopathological features, biological nature,
anatomical location, sex, age and breeds of dogs affected by spontaneous gastrointestinal
epithelial tumor. Biopsy samples of gastrointestinal tumors, from 95 dogs were examined
and classified according to the WHO histological classification. A total of 131 samples,
including 38 gastric, 13 small intestinal, and 80 large intestinal tumors were examined.
The study observed that Jack Russell Terriers and Miniature Dachshunds were the breeds
with the highest predisposition for gastrointestinal tumors. Gastric tumors included 5
adenomas, 30 adenocarcinomas (12 tubular, 2 papillary, 4 tubulopapillary and 12
signet-ring cell carcinomas) and 3 undifferentiated carcinomas. Intestinal tumors included
35 adenomas, 57 adenocarcinomas (43 acinar, 4 papillary, 7 mucinous and 3 signet-ring cell
carcinomas), and 1 undifferentiated carcinoma. The study did not detect any difference
among the incidence rates of invasion/metastasis in the tubular (44%), papillary (33%) and
tubulopapillary (25%) adenocarcinomas. Additionally, the tubular (acinar), papillary and
tubulopapillary adenocarcinomas were further divided into 48 polypoid and 17 non-polypoid
types, based on their growth patterns. Invasion/metastasis was detected in 21% of the
polypoid type and 100% of the non-polypoid type of adenocarcinomas. A correlation was
detected between the occurrence of invasion/metastasis and the type of histopathological
growth pattern in adenocarcinomas. The study demonstrated that Jack Russell terriers and
Miniature Dachshunds are the most common breeds affected by gastrointestinal tumors and
the entire group of the canine adenocarcinomas with non-polypoid growth pattern has
greater malignant potentials, compared to the adenocarcinomas with polypoid growth
patterns.

Vet Immunol Immunopathol 2019; 218:109938. [PMID: 31518913 DOI: 10.1016/j.vetimm.2019.109938] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 08/18/2019] [Accepted: 08/31/2019] [Indexed: 02/07/2023]
Abstract
Inflammatory colorectal polyp (ICRP) is an emerging disease in Miniature Dachshunds (MDs). Animals with this disease exhibit multiple polyps with severe neutrophil infiltration that respond to immunosuppressive therapy. Macrophages in polypoid lesions have been described to play an important role in neutrophil infiltration in the lesion by producing IL-8. In contrast, IL-10, an anti-inflammatory cytokine, was also reported to be upregulated in polypoid lesions, but its significance in the pathogenesis of ICRP has not been clarified. Regulatory T cells (Tregs) are the main source of IL-10 production and contribute to the maintenance of intestinal homeostasis. Therefore, the objective of this research was to compare the distribution of Tregs in polypoid lesions of ICRPs and the association between the distribution and expression of pro- or anti-inflammatory cytokines. Tissue biopsy specimens of polypoid lesions were collected from 28 MDs with ICRP. Those of macroscopically non-polypoid colonic mucosa from 24 MDs with ICRPs and 21 control dogs were further included as controls. Real-time quantitative polymerase chain reaction was used to quantify gene expression of IL-1β, IL-4, IL-6, IL-8, IL-10, IL-17, IL-22, IFN-γ, TNF-α, TGF-β, and forkhead box protein P3 (Foxp3) in each tissue sample. The numbers of Foxp3-positive cells (Tregs) and ionized calcium binding adapter molecule 1 (Iba-1)-positive cells (macrophages) were determined by immunohistochemistry. The gene expression of IL-1β, IL-6, IL-8, TNF-α, IFN-γ, IL-17, IL-10, TGF-β, and Foxp3 was significantly upregulated in polypoid lesions relative to control levels. The numbers of Foxp3-positive Tregs and Iba-1-positive macrophages were significantly increased in polypoid lesions compared to those in the non-polypoid colonic mucosa of MDs with ICRPs and control dogs. The upregulation of IL-10 was moderately correlated with the distribution of Tregs in polypoid lesions from MDs with ICRPs. In addition, the relative upregulation of IL-1β, IL-6, and IL-8 in polypoid lesions, compared to expression in non-polypoid colonic mucosa of MDs with ICRPs, was significantly greater than that of IL-10. These results indicate that increases in Treg numbers and anti-inflammatory cytokines in polypoid lesions comprise reactive changes in response to the inflammation, which warrants further investigation.

Abstract
Biopsy samples of colorectal polyps were collected and examined from 67 Miniature Dachshund dogs (including 35 cases with an additional biopsy). Histopathologic diagnoses of the initial biopsy samples were "inflammatory polyp" in 52 cases (78%), "adenoma" in 10 cases (15%), and "adenocarcinoma" in 5 cases (8%). Eight of 10 cases (80%) diagnosed as adenoma also had inflammatory polyp lesions in the same specimen. A second biopsy was performed in 25 cases (48%) initially diagnosed with inflammatory polyp. Pathologic diagnoses for the second biopsy were inflammatory polyp in 11 cases (44%), adenoma in 9 cases (36%), and adenocarcinoma in 5 cases (20%). The number of beta-catenin-positive nuclei in epithelial cells was significantly higher in adenoma (46%) and adenocarcinoma (75%) as compared with inflammatory polyp (6%). Normal epithelial cells and hyperplastic goblet cells in inflammatory polyps showed homogeneous positive cytoplasmic immunoreactivity for adenomatous polyposis coli (APC) antigen. However, APC expression was decreased in areas of intense nuclear beta-catenin expression in adenoma and adenocarcinoma lesions. Foci of cytokeratin 5/6-positive squamous cell-like neoplastic cells showed intense beta-catenin nuclear expression that was similar to squamous morules described in human colorectal tumors. The results of the present study suggest that the inflammatory polyp in Miniature Dachshunds is a progressive disease that may develop into adenoma and/or adenocarcinoma. In addition, immunohistochemical findings suggest that aberrations of APC and beta-catenin expression may be involved in tumor development within the inflammatory polyp lesions.

Abstract
Inflammatory colorectal polyps (ICRP), which are more commonly recognized in miniature dachshunds, are thought to represent an immune-mediated disease. This retrospective case series describes six miniature dachshunds with refractory ICRP, who were treated with chlorambucil (CLB) combined with firocoxib or prednisolone. Improvement in clinical manifestations was seen in five of the six dogs by the end of the study period; four were treated with CLB/firocoxib and one with CLB/prednisolone. One dog had nonregenerative anemia after 23 mo of treatment with CLB, but whether there was a causative relationship was unclear. No severe adverse events were observed during treatment in the remaining five dogs. CLB in combination with firocoxib or prednisolone appears to be an effective alternative treatment for ICRP in dogs. Further studies are needed to confirm the effectiveness and long-term complications of CLB treatment for ICRP in dogs.

Abstract
By using a complex of DNA, polyethylenimine and chondroitin sulfate, the in
vivo transfection of early secretory antigenic target-6 (ESAT-6) gene into
tumor cells was found to cause significant suppression of the tumor growth. In order to
apply the method in clinical cancer treatment in dogs and cats, mechanisms underlying the
suppressive effects were investigated in a tumor-bearing mouse model. The transfection
efficiency was only about 10%, but the transfection of ESAT-6 DNA nevertheless induced
systemic immune responses against ESAT-6. By triple injection of ESAT-6 DNA at three day
intervals, the tumor was significantly reduced and almost disappeared by 5 days after the
start of treatment, and did not increase for more than 15 days after the final treatment.
In the immunohistochemistry, a larger number of dendritic cells (DCs)/macrophages
expressing ionized calcium-binding adapter molecule 1 and CD3+ T cells was
observed in tumors treated with ESAT-6 DNA, and their population further increased
significantly by day 5. Moreover, the amount of tumor necrosis factor, which is an
apoptosis-inducing factor produced mainly by DCs/macrophages, was greater in the ESAT-6
DNA treated tumors than in controls, and increased with repeat of the treatment. These
results indicate that in vivo transfection of ESAT-6 DNA into tumor cells
elicits significant inhibition of tumor growth by inducing potent activity of innate
immunity mediated by DCs/macrophages, which may be followed by adaptive immunity against
tumor associated antigens, elicited by the costimulation with ESAT-6 antigen.

Abstract
Short chain fatty acids (SCFAs) play an important role in the maintenance of colonic
homeostasis, and their depletion has been reported in various gastrointestinal disorders.
Inflammatory colorectal polyps (ICRPs) are a recently recognized disease specific to
miniature dachshunds (MDs), and fecal dysbiosis with a reduction of SCFA-producing
bacteria has been reported with this disease. Therefore, this study was performed based on
the hypothesis that a reduced SCFA concentration associates with the development of ICRPs.
We recruited 11 ICRP-affected MDs and 25 control MDs. Their fecal SCFA concentrations and
bacterial proportions were quantified using high performance liquid chromatography and
quantitative real-time PCR, respectively. The feces of ICRP-affected MDs contained lower
amounts of propionic acid and lower proportions of Bifidobacterium than
the feces of control MDs. Furthermore, fecal proportions of
Bifidobacterium, Firmicutes and Lactobacillus
exhibited significant positive correlations with fecal concentrations of total SCFAs
and/or propionic acid; fecal Escherichia coli proportions correlated
negatively with fecal concentrations of total SCFAs, as well as acetic, propionic and
butyric acid. This result indicates an association between fecal dysbiosis and fecal SCFA
concentrations; these phenomena may contribute to ICRP pathogenesis in MDs. Potential
therapeutic targeting of the reduced propionic acid concentration using probiotics,
prebiotics or SCFA enemas merits further study.

Abstract
Inflammatory colorectal polyps (ICRPs) in miniature dachshunds (MDs) are a possible novel form of breed-specific canine inflammatory bowel disease (IBD). In this pilot study, we investigated the effects of different Toll like receptor (TLR2, TLR4, TLR5 and TLR9) ligands on pro-inflammatory cytokines (IL-1β, IL-6, IL-8 and TNF-α) gene expression in ex vivo-cultured colorectal samples from four MDs with ICRPs and four healthy MDs. At baseline, no significant difference in the mRNA expression levels of TLRs and pro-inflammatory cytokines was observed between cases and control MDs. After 4-h incubation, the relative ratios of TNF-α mRNA expression in the TLR2- or TLR4-stimulated colorectal samples, and IL-1β mRNA expression in the TLR9-stimulated colorectal samples form cases showed higher tendency compared with healthy MDs (P<0.05), although statistically not significant. The results of this pilot study using small number of cases indicated that reactivity against TLR2, TLR4 or TLR9 ligand in the production of pro-inflammatory cytokines might be enhanced in the colorectal mucosa of ICRPs. Further research is needed to perform the functional analysis of TLRs in the sole cell population using intestinal epithelial primary culture and the mononuclear cells isolated from colonic mucosa.

Abstract
An endoscopic examination revealed a mass in the distal esophagus of a 9-year-old intact male bulldog. Histopathologically, the mass was composed of cuboidal to columnar neoplastic epithelial cells and extended from the squamous epithelium of the esophageal mucosa, indicating that the tumor was derived from Barrett’s esophagus. Moreover, highly atypical foci that exhibited a cribriform pattern and high mitotic indices were also observed. The epithelial cells on the surface of the lesion often produced mucus that was positive for Alcian blue and immunohistochemically positive for MUC5AC. The neoplastic epithelial cells were diffusely positive for cytokeratin 7 and p53, and occasionally positive for cytokeratin 20. Based on these findings, the tumor was diagnosed as an adenocarcinoma. This report describes the clinical and pathological features of a spontaneous case of adenocarcinoma of Barrett’s esophagus in a dog.

Abstract
We examine the expression of tight junction and adherence junction proteins in the colorectal mucosa of miniature dachshunds (MDs) with inflammatory colorectal
polyps (ICRPs). Colorectal mucosa samples were endoscopically obtained from 8 MDs with ICRPs and 8 control dogs for immunoblotting. Paraffin-embedded tissues of
surgically resected inflamed lesions from another 5 MDs with ICRPs and full-thickness colorectal specimens from 5 healthy beagles were obtained for
immunohistochemistry. The expression patterns of claudin-1, -2, -3, -4, -5, -7 and -8, E-cadherin and β-catenin were analyzed in the non-inflamed mucosa and
inflamed mucosa of ICRPs and colorectal mucosa of control dogs by immunoblotting. The localization of these proteins in the inflamed lesions was analyzed by
immunohistochemistry. The expressions of each of claudin, E-cadherin and β-catenin were not significantly different between control dogs and non-inflamed
colonic mucosa from MDs with ICRPs. In contrast, only E-cadherin and β-catenin were detected in the inflamed lesions of MDs with ICRPs. By immunohistochemistry,
claudin-2, -3, -4, -5 and -7, E-cadherin and β-catenin were expressed in the colorectal epithelium within the inflamed mucosa, but not in granulation tissue.
Distributions of claudin-2, -3, -4, -5, and -7, E-cadherin and β-catenin in the colonic epithelium were not different between MDs with ICRPs and control dogs.
These results indicated that no significant alteration was detected in several tight junction or adherence junction proteins expression in the colorectal
epithelium of ICRPs.

Localization of Toll-like Receptor (TLR) 2 and TLR4 mRNA in the Colorectal Mucosa of Miniature Dachshunds with Inflammatory Colorectal Polyps. J Comp Pathol 2017; 156:183-190. [PMID: 28089357 DOI: 10.1016/j.jcpa.2016.10.010] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2016] [Revised: 09/30/2016] [Accepted: 10/22/2016] [Indexed: 01/03/2023]
Abstract
Inflammatory colorectal polyps (ICRPs) are characterized by the formation of multiple or solitary polyps with marked neutrophil infiltration in the colorectal area, and are speculated to be a novel form of breed-specific canine idiopathic inflammatory bowel disease (IBD). In human IBD, toll-like receptor (TLR) 2 and TLR4 have been reported to be involved in the pathogenesis of the disease. The aim of this study was to evaluate the expression of TLR2 and TLR4 mRNA in the colorectal mucosa of dogs with ICRPs by in-situ hybridization using an RNAscope assay. Samples of inflamed colorectal mucosa (n = 5) and non-inflamed mucosa (n = 5) from miniature dachshunds (MDs) with ICRPs and colonic mucosa from healthy beagles (n = 5) were examined. TLR2 and TLR4 hybridization signals were localized to the colorectal epithelium, inflammatory cells and fibroblasts in the inflamed colorectal mucosa of affected dogs. The signals were significantly greater in inflamed colorectal epithelium compared with non-inflamed epithelium of MDs with ICRPs and healthy beagles (P <0.05). These results suggest that increased expression of TLR2 and TLR4 mRNA in the inflamed colorectal mucosa results from not only inflammatory cell infiltration, but also the upregulation of TLR2 and TLR4 mRNA in the colonic epithelium.
