Abstract
Five previously unknown isotopes (^{182,183}Tm, ^{186,187}Yb, ^{190}Lu) were produced, separated, and identified for the first time at the Facility for Rare Isotope Beams (FRIB) using the Advanced Rare Isotope Separator (ARIS). The new isotopes were formed through the interaction of a ^{198}Pt beam with a carbon target at an energy of 186 MeV/u and with a primary beam power of 1.5 kW. Event-by-event particle identification of A, Z, and q for the reaction products was performed by combining measurements of the energy loss, time of flight, magnetic rigidity Bρ, and total kinetic energy. The ARIS separator has a novel two-stage design with high resolving power to strongly suppress contaminant beams. This successful new isotope search was performed less than one year after FRIB operations began and demonstrates the discovery potential of the facility which will ultimately provide 400 kW of primary beam power.

Extreme low pH, not Al 3+ , is a key abiotic stressor for the extremophyte Carex angustisquama (Cyperaceae) in highly acidic solfatara fields. Plant Biol (Stuttg) 2023; 25:551-562.

Abstract
Volcanic acidification creates extreme soil conditions, where rhizotoxicity from extremely low pH (2-3) and high Al3+ strongly inhibit plant growth. C. angustisquama is a dominant extremophyte in highly acidic solfatara fields, where no other vascular plants can survive. Here we investigated the key abiotic stressor determining survival of this extremophyte. Soil analyses and topographic surveys were conducted to examine the effects of low pH and Al3+ , two major abiotic stressors in acidic soils, on the occurrence of C. angustisquama in solfatara fields. Hydroponic culture experiments were also performed to test its growth responses to these stressors. In field surveys, the spatial distribution of soil pH was consistent with vegetation zonation within a solfatara field. In contrast, soil exchangeable Al content was overall low due to strong eluviation. Statistical analysis also supported the significant role of soil pH in determining the distribution of C. angustisquama in a solfatara field. Furthermore, hydroponic culture experiments revealed a higher tolerance of C. angustisquama to low pH than a sister species, especially in the range pH 2-3, corresponding to the pH values of the actual habitats of C. angustisquama. Conversely, no significant interspecific difference was detected in Al3+ tolerance, indicating that both species had high Al3+ tolerance. This study suggests that low pH is a critical abiotic stressor leading to formation of the extremophyte in highly acidic solfatara fields. In contrast, C. angustisquama displayed high tolerance to Al3+ toxicity, probably acquired prior to speciation.

Abstract
OBJECTIVES Gastroesophageal reflux can occur during anaesthesia and may lead to esophagitis and occasionally oesophageal stricture formation. The aim of the study is to assess two omeprazole protocols on gastroesophageal reflux incidence and pH in anaesthetised dogs. MATERIALS AND METHODS Fifty-five dogs undergoing elective ovariectomy were randomly assigned to: omeprazole single dose 1 mg/kg orally the evening before anaesthesia (20 dogs), omeprazole two doses 1 mg/kg orally the evening and 3 hours before anaesthesia (15 dogs), and control group that did not receive omeprazole (20 dogs). An oesophageal impedance/pH probe was used to measure gastroesophageal reflux incidence and pH during anaesthesia. RESULTS Gastroesophageal reflux was observed in 55% (11/20) of control dogs, 55% (11/20) of dogs receiving omeprazole once and 47% (7/15) of dogs receiving omeprazole twice. The incidence was not statistically significant different between groups. Gastroesophageal reflux pH (mean ± sd) was higher in dogs receiving omeprazole twice (6.3 ± 1.5), when compared to either control dogs (3.8 ± 1.1) or dogs receiving omeprazole once (4.1 ± 1.5). Strongly acidic reflux (pH < 4) was observed in 7% (1/15) of dogs receiving omeprazole twice versus 55% (11/20) and 35% (7/20) of control dogs and dogs receiving omeprazole once, respectively. CLINICAL SIGNIFICANCE Omeprazole administered the evening and 3 hours before anaesthesia increased gastroesophageal reflux pH and decreased the incidence of strongly acidic reflux in dogs. A single dose of omeprazole given the evening before anaesthesia had no effect on reflux pH.

Abstract
Experimental studies of the simultaneous acceleration of three-charge-state ^{129}Xe^{49+,50+,51+} beam from 17 to 180 MeV/nucleon in a superconducting linear accelerator are presented. The beam parameters for each individual- and multiple-charge-state beam were measured and compared with the particle tracking simulations. Detailed measurements were performed to characterize the multiple-charge-state beam's recombination after a second-order achromat and isopath 180° bending system. As a result of the recombination of three charge states in the six-dimensional phase space, the xenon beam intensity was increased by 2.5-fold compared to the single-charge-state beam. The results presented in the Letter fully validate the possibility to produce and utilize high-quality multiple-charge-state heavy-ion beams in a large-scale superconducting linac to increase the available beam power on an isotope production target.

Abstract
Abstract
Background
The high dose (20mg/day) of apixaban is used for the initial treatment of venous thromboembolism for the first week. Although patients taking direct oral anticoagulants do not require routine coagulation monitoring, the correlations between anti-factor Xa activity (AXA) and routine coagulation markers such as prothrombin time (PT) and activated partial thromboplastin time (APTT) at peak and trough times especially when using high dose of apixaban have not been reported so far.
Purpose
The purpose is to assess the correlations between AXA values and PT/APTT at peak and trough times in patients with venous thromboembolism using high dose of Apixaban.
Methods
Twenty-six patients (10 male; 71±15 years) with proximal venous thromboembolism or pulmonary embolism using high dose (20mg/day) of apixaban were enrolled. We measured AXA, using chromogenic assay with the HemosIL Liquid Heparin kit, PT and APTT at peak and trough times. The peak time was defined as 3 hours after the intake of apixaban, and the trough time was defined as that immediately before the intake of apixaban.
Results
A significant and strong positive correlation was observed between AXA and PT at both peak and trough times (R=0.795, p<0.01 and R=0.766, p<0.01, respectively). A significant and moderate positive correlation was observed between AXA and APTT at trough time (R=0.527, p<0.01), but no correlation was observed between AXA and APTT at peak time (R=0.366, p=0.07).
Conclusion
Our findings reveal the relationship between AXA and PT at peak and trough times has a significant strong correlation. These results suggest measuring of PT may be alternative and effective way of monitoring of AXA values when using high dose of apixaban.

Abstract
Abstract
Background
Although patients taking direct oral anticoagulants (DOACs) do not require routine coagulation monitoring, the distribution of anti-factor Xa activity (AXA) values, prothrombin time (PT), PT-international normalized ratio (INR) and activated partial thromboplastin time (APTT) in patients on apixaban, edoxaban and rivaroxaban therapy is still not clear.
Purpose
The aim is to set the standard values of AXA values, PT, PT-INR and APTT in patients using DOACs.
Methods
We measured AXA, using chromogenic assay with the HemosIL Liquid Heparin kit, PT, PT-INR and APTT at trough and peak times in 224 patients with non-valvular atrial fibrillation and venous thromboembolism, of whom 90 received apixaban, 100 received edoxaban and 34 received rivaroxaban. The peak time was defined as 3 hours after the intake of apixaban or rivaroxaban, and 2 hours after the intake of edoxaban. The trough time was defined as that immediately before the intake. The AXA values, PT, PT-INR and APTT were measured at least 72 hours after the start of treatment. The dosage of DOACs is defined according to the prescribing information in Japan.
Results
(The order of results below is apixaban, edoxaban and rivaroxaban, respectively.) The average AXA values were 2.29, 0.23 and 0.39 (IU/mL) at trough time, and 3.04, 1.01 and 1.70 (IU/mL) at peak time. The average PT values were 17.9, 12.9 and 13.1 (s) at trough time, and 19.7, 15.5 and 17.5 (s) at peak time. The average PT-INR values were 1.49, 1.07 and 1.08 at trough time, and 1.65, 1.29 and 1.45 at peak time. The average APPT values were 34.5, 31.3 and 32.0 (s) at trough time, and 39.5, 35.9 and 39.8 (s) at peak time.
Conclusion
Our findings reveal the standard values of AXA, PT, PT-INR and APTT in patients using apixaban, edoxaban and rivaroxaban in each dosage. The DOACs should be changed if the measured value is out of those standard values in 90% confidence interval.

Abstract
Abstract
Purpose
Papillary muscle ischemia (PMI) is caused by micro-vessels' occlusion in the broad endocardium because papillary muscle perfusion is supply from micro-vessels of peripheral coronary arteries and is easy to fail by the increase in peripheral vascular resistance. However, the clinical significant is not understood because PMI could not be detected by existing perfusion imaging such as SPECT and MRI. We propose the detection method of PMI using 13N-ammonia PET (NH3-PET), and investigate the association with the global myocardial flow reserve (Global-MFR) reflecting coronary microvascular dysfunction.
Methods
Data of adenosine-stress NH3-PET for consecutive 260 patients with coronary artery disease (CAD) or suspected CAD was retrospectively analyzed. Using high-resolution cine imaging derived from NH3-PET, PMI was defined as the absence of the PM accumulation at stress conditions. Myocardial flow was generated from the time activity curve of left ventricle input and myocardial uptake using 3-compartment model and the first 2 minutes' dataset of list mode images. Global-MFR was calculated by stress to rest flow ratio. Summed stress score (SSS) was used as an estimate of the extent of myocardial ischemia. 150 out of 260 patients (58%) with SSS ≥4 or with the past history of coronary artery diseases were classified as ischemic group, and 110 patients (42%) with SSS<4 were classified as non-ischemic group.
Results
PMI was seen in 68 of 260 patients (26.6%). The frequency of PMI was higher in the ischemic group than the non-ischemic group (37.8% vs. 10.1%, p<0.0001). Global-MFR was significantly lower in patients with PMI than those without (1.87±0.55 vs. 2.39±0.80, p<0.0001). In both ischemic and non-ischemic group, global-MFR was significantly reduced in patients with PMI. (Ischemic group: 1.83±0.56 vs. 2.12±0.52, p=0.0043, Non-ischemic group: 2.06±0.45 vs. 2.63±0.91, p=0.040).
Typical case of PMI
Conclusion
High-resolution cine imaging derived from NH3-PET makes it possible to detect PMI in about a quarter of patients with CAD or suspected CAD. PMI associates with reduced Global-MFR regardless of the presence of myocardial ischemia, suggesting that PMI is an important sign of early ischemia confined to the papillary muscle or the broad microvascular injury.

Abstract
Score sheets were first introduced 30 years ago to assess pain, distress and suffering in animals. To date, however, there is still no general agreement on their use in research practice, and only a few publications can be found on this topic. In the present work, we demonstrate the use of a special score sheet for severity assessment in the first three postoperative days in two showcased studies performed on Wistar and Lewis rats undergoing liver resection or orthotopic liver transplantation, respectively. Scoring of different criteria and the total score were evaluated within each intervention. Additionally, both procedures were compared regarding their degree of severity. Suitability of these score sheets was evaluated for assessing severity of the procedures and these showed a minor severity within each investigated study. A comparison of both studies showed slightly higher scores involving liver transplantation. In contradiction to the common classification of these procedures as a moderate severity grade the score sheets applied here indicates a minor severity grade within each investigated study. Also, limitations and possible improvements in the design of our score sheets for defined interventions are reconsidered.

Abstract
Although cytology is a rapid diagnostic procedure in dogs, the cytologic criteria of endoscopic biopsies for chronic enteritis and intestinal lymphoma are not well defined. An immediate diagnosis using cytology would benefit patients by enabling prompt initiation of therapy. The objective of this study was to investigate the correlation between the results of endoscopic cytology and histopathology. In this study, 167 dogs with clinical signs of chronic gastrointestinal disease were included. On the basis of histopathology, the following diagnoses were determined: lymphocytic-plasmacytic enteritis in 93 dogs; eosinophilic enteritis in 5 dogs; small cell intestinal lymphoma in 45 dogs; and large cell intestinal lymphoma in 24 dogs. Two clinical pathologists retrospectively evaluated the endoscopic cytology of squash-smear preparations. The cytologic diagnoses of inflammation, small cell lymphoma, and large cell lymphoma were based on the severity of lymphocyte infiltration, the size of infiltrated lymphocytes, and eosinophil/mast cell infiltration. The clinical severity score was significantly increased along with the degree of lymphocyte infiltration evaluated by cytology. The cytologic diagnosis was in complete agreement with the histopathologic diagnosis in 136 of 167 (81.4%) cases. For the differentiation between enteritis and lymphoma, endoscopic cytology had a sensitivity of 98.6%, a specificity of 73.5%, a positive predictive value of 72.3%, and a negative predictive value of 98.6%. The log-rank test and Cox regression analysis showed that the results of cytology predicted the prognosis. These results suggest that endoscopic cytology is a useful technique to aid diagnosis of intestinal inflammation and lymphoma in dogs.

Abstract
OBJECTIVE To reveal the relationship between canine corticosteroid-induced alkaline phosphatase isoenzyme activity and hepatobiliary diseases. MATERIALS AND METHODS Retrospective analysis of the relationship between serum corticosteroid-induced alkaline phosphatase activity and diagnosis, serum cortisol concentration and alanine transferase activity in dogs with hepatobiliary diseases. Dogs with a history of glucocorticoid administration were excluded. RESULTS Seventy-two dogs with hepatobiliary diseases were analysed. The serum corticosteroid-induced alkaline phosphatase concentration was increased in dogs with hepatobiliary diseases. There was no correlation between serum cortisol concentration and serum corticosteroid-induced alkaline phosphatase percentage or activity. CLINICAL SIGNIFICANCE Dogs with hepatobiliary disease can exhibit high serum alkaline phosphatase activity even if the dogs have not been administrated glucocorticoids and the serum cortisol concentration is normal.

Abstract
Although the recognition of pain, distress and discomfort has already been described in 1985 by Morton and Griffiths there is still very little known about the establishment of score sheets especially, regarding post-surgical pain and severity assessment for laboratory animals such as rabbits. In this paper we describe the estimation of severity and recovery status of 36 female New Zealand White rabbits (NZW) in a standardized liver resection model using two different adhesive treatments and one control group. Welfare was assessed at 3–4 consecutive days after surgery using a scoring system which included the following criteria: body weight, general state, clinical results, spontaneous behavior and clinical examination. Values could range from 0 to 20 where increasing values indicated increasing severity with a predefined humane endpoint for a score ≥20 points. Documented score points were almost exclusively a result of body weight loss, whereas clinical signs and general health status had no influence on the overall sum of points scored. Behavioral variation was solely observed postoperatively, within the first 24 h, with an average score ≤1. In contrast to the classification of a laparotomy as a moderate procedure in the EU Directive 2010/63 (annex VIII) the assessment herein presented showed a mild burden in all groups according to the scoring system used. The partial hepatectomy itself, as well as the adhesive treatment using either synthetic glue VIVO-107 or fibrin glue, were well tolerated.

Abstract
With about 1000-h of relativistic high-energy ion beams provided by Heavy Ion Medical Accelerator in Chiba, about 70 users are performing various biology experiments every year. A rich variety of ion species from hydrogen to xenon ions with a dose rate of several Gy/min is available. Carbon, iron, silicon, helium, neon, argon, hydrogen, and oxygen ions were utilized between 2012 and 2014. Presently, three electron cyclotron resonance ion sources (ECRISs) and one Penning ion source are available. Especially, the two frequency heating techniques have improved the performance of an 18 GHz ECRIS. The results have satisfied most requirements for life-science studies. In addition, this improved performance has realized a feasible solution for similar biology experiments with a hospital-specified accelerator complex.

Abstract
There is a desire that a carbon-ion radiotherapy facility will produce various ion species for fundamental research. Although the present Kei2-type ion sources are dedicated for the carbon-ion production, a future ion source is expected that could provide: (1) carbon-ion production for medical use, (2) various ions with a charge-to-mass ratio of 1/3 for the existing Linac injector, and (3) low cost for modification. A prototype compact electron cyclotron resonance (ECR) ion source, named Kei3, based on the Kei series has been developed to correspond to the Kei2 type and to produce these various ions at the National Institute of Radiological Sciences (NIRS). The Kei3 has an outer diameter of 280 mm and a length of 1120 mm. The magnetic field is formed by the same permanent magnet as Kei2. The movable extraction electrode has been installed in order to optimize the beam extraction with various current densities. The gas-injection side of the vacuum chamber has enough space for an oven system. We measured dependence of microwave frequency, extraction voltage, and puller position. Charge state distributions of helium, carbon, nitrogen, oxygen, and neon were also measured.

Abstract
BACKGROUND/PURPOSE In oxidative coloring, the hair cuticle layers are not only the penetration pathway for active ingredients but also one of the most important dyeing regions. The dyeing mechanism of oxidative dyes in fine structures of the cuticle remains unclear. To investigate the dyeing behavior of oxidative dyes in fine structures of the cuticle, hair cross-sections were analyzed by nanoscale secondary ion mass spectrometry (NanoSIMS). METHODS The preparation method of hair cross-section for NanoSIMS measurement was improved. Improved hair cross-sections were analyzed using NanoSIMS. RESULTS The cuticle layer thickness of the hair cross-section could be widened. It was confirmed that (12) C(-) ions were more strongly detected from endocuticle than from other fine structures of cuticle. The NanoSIMS (12) C(-) image and hue saturation intensity (HSI) D(-) /(1) H(-) ratio image of the hair, dyed with deuterium-labeled oxidative dye, indicated that the endocuticle had a higher D(-) /(1) H(-) ratio than the other fine structures of the cuticle. It was substantiated that more colored chromophores were fixated in the endocuticle than in other fine structures of the cuticle. CONCLUSION The dyeing behavior of oxidative dyes in fine structures of hair cuticle was substantiated by NanoSIMS analysis using the improved hair cross-section preparation method.

Abstract
In this study, plasma MMP-9 activity was evaluated in cats with lymphoma. Plasma samples were obtained from 26 cats with lymphoma before treatment. From 13 of the included 26 cats, plasma samples were obtained 4 weeks after the initiation of treatment. Plasma samples were also obtained from 10 healthy cats as a control. Plasma MMP-9 activity was examined by gelatin zymography and semi-quantitative value (arbitrary unit; a.u.) for each sample was calculated. Relatively high levels of MMP-9 were observed in cats with lymphoma compared with those in healthy control cats. MMP-9 quantification through zymography showed significantly higher activity in cats with lymphoma (median, 0.63 a.u.; range, 0.23-3.24 a.u.) than in healthy controls (0.22 a.u.; 0.12-0.46 a.u.; P < 0.01). MMP-9 activities were significantly different before (0.73 a.u.; 0.30-3.24 a.u.) and after treatment (0.50 a.u.; 0.14-1.32 a.u.; P = 0.017). Measuring plasma MMP-9 activity in cats with lymphoma may become an appropriate monitoring tool for feline lymphoma.

Abstract
Canine extrahepatic congenital portosystemic shunts (EH-cPSS) are classified into several anatomical types, depending on the origin and termination of the shunt vessel. The aim of this retrospective study was to determine the proportion and clinical features of each anatomical shunt type in a population of dogs presented to a veterinary teaching hospital in Japan. Dogs diagnosed with EH-cPSS using computed tomographic (CT) portography were included (n=172) and shunts were classified based on previous reports. Clinical data were collected from case records and analysed statistically. The most common anatomical type was the spleno-phrenic shunt (n=64), followed by the spleno-azygos (n=38), right gastric-caval (n=29), spleno-caval (n=21), right gastric-caval with caudal loop (n=9), right gastric-phrenic (n=6), colono-caval (n=3), spleno-phrenic and azygos (n=1), and porto-caval (n=1) shunts. Spleno-phrenic and spleno-azygos shunts were diagnosed more frequently in older dogs than right gastric-caval and spleno-caval shunts (P<0.05). The portal vein/aortic (PV/Ao) ratio was significantly larger in dogs with spleno-phrenic shunts than in dogs with spleno-azygos, right gastric-caval or spleno-caval shunts (P<0.05). The PV/Ao ratio was significantly larger in dogs with spleno-azygos shunts than in dogs with right gastric-caval shunts. Dogs with spleno-phrenic shunts had significantly lower serum alkaline phosphatase activities than those with right gastric-caval or spleno-caval shunts. Dogs with spleno-phrenic shunts had significantly lower fasting ammonia concentrations than those with spleno-caval shunts.

Abstract
The diagnosis of gall bladder mucoceles (GM) in dogs has become increasingly frequent in veterinary medicine. Primary breed-specific hyperlipidaemia is reported in Shetland Sheepdogs and Miniature Schnauzers, breeds in which GM are known to occur more frequently than in other breeds. The objective of this study was to evaluate the association between GM and hyperlipidaemia in dogs. The study design was a retrospective case control study. Medical records of dogs diagnosed with GM at the Veterinary Medical Centre of The University of Tokyo between 1 April 2007 and 31 March 2012, were reviewed. Fifty-eight dogs with GM and a record of either serum cholesterol, triglyceride, or glucose concentrations were included in the study. Hypercholesterolaemia (15/37 cases; odds ratio [OR]: 2.92; 95% confidence interval [CI]: 1.02-8.36) and hypertriglyceridaemia (13/24 cases; OR: 3.55; 95% CI:1.12-15.91) showed significant association with GM. Pomeranians (OR: 10.69), American Cocker Spaniels (OR: 8.94), Shetland Sheepdogs (OR: 6.21), Miniature Schnauzers (OR: 5.23), and Chihuahuas (OR: 3.06) were significantly predisposed to GM. Thirty-nine out of 58 cases had at least one concurrent disease, including pancreatitis (five cases), hyperadrenocorticism (two cases), and hypothyroidism (two cases). A significant association between GM and hyperlipidaemia was confirmed, suggesting that hyperlipidaemia may play a role in the pathogenesis of GM.

Abstract
An X-ray intravital microscopy technique was developed to enable in vivo visualization of the coronary, cerebral, and pulmonary arteries in rats without exposure of organs and with spatial resolution in the micrometer range and temporal resolution in the millisecond range. We have refined the system continually in terms of the spatial resolution and exposure time. X-rays transmitted through an object are detected by an X-ray direct-conversion type detector, which incorporates an X-ray SATICON pickup tube. The spatial resolution has been improved to 6 μm, yielding sharp images of small arteries. The exposure time has been shortened to around 2 ms using a new rotating-disk X-ray shutter, enabling imaging of beating rat hearts. Quantitative evaluations of the X-ray intravital microscopy technique were extracted from measurements of the smallest-detectable vessel size and detection of the vessel function. The smallest-diameter vessel viewed for measurements is determined primarily by the concentration of iodinated contrast material. The iodine concentration depends on the injection technique. We used ex vivo rat hearts under Langendorff perfusion for accurate evaluation. After the contrast agent is injected into the origin of the aorta in an isolated perfused rat heart, the contrast agent is delivered directly into the coronary arteries with minimum dilution. The vascular internal diameter response of coronary arterial circulation is analyzed to evaluate the vessel function. Small blood vessels of more than about 50 μm diameters were visualized clearly at heart rates of around 300 beats/min. Vasodilation compared to the control was observed quantitatively using drug manipulation. Furthermore, the apparent increase in the number of small vessels with diameters of less than about 50 μm was observed after the vasoactive agents increased the diameters of invisible small blood vessels to visible sizes. This technique is expected to offer the potential for direct investigation of mechanisms of vascular dysfunctions.

Abstract
BACKGROUND Although immunoglobulin A (IgA) plays a key role in regulating gut homeostasis, its role in canine inflammatory bowel disease (IBD) is unknown. HYPOTHESIS IgA expression may be altered in dogs with IBD, unlike that observed in healthy dogs and dogs with other gastrointestinal diseases. ANIMALS Thirty-seven dogs with IBD, 10 dogs with intestinal lymphoma, and 20 healthy dogs. METHODS Prospective study. IgA and IgG concentrations in serum, feces, and duodenal samples were measured by ELISA. IgA(+) cells in duodenal lamina propria and IgA(+) CD21(+) peripheral blood mononuclear cells (PBMCs) were examined by immunohistochemistry and flow cytometry, respectively. Duodenal expression of the IgA-inducing cytokine transforming growth factor β (TGF-β), B cell activating factor (BAFF), and a proliferation-inducing ligand (APRIL) was quantified by real-time RT-PCR. RESULTS Compared to healthy dogs, dogs with IBD had significantly decreased concentrations of IgA in fecal and duodenal samples. The number of IgA(+) CD21(+) PBMCs and IgA(+) cells in duodenal lamina propria was significantly lower in dogs with IBD than in healthy dogs or dogs with intestinal lymphoma. Duodenal BAFF and APRIL mRNA expression was significantly higher in IBD dogs than in the healthy controls. Duodenal TGF-β mRNA expression was significantly lower in dogs with IBD than in healthy dogs and dogs with intestinal lymphoma. CONCLUSIONS AND CLINICAL IMPORTANCE IBD dogs have decreased IgA concentrations in feces and duodenum and fewer IgA(+) PBMCs, which might contribute to development of chronic enteritis in dogs with IBD.

Abstract
Involvement of the aryl hydrocarbon receptor (AHR) in carcinogenesis has been suggested in many studies. Upregulation of AHR has been reported in some cancer species, and an association between single-nucleotide polymorphisms (SNPs) of AHR and cancer risk or cancer development has also been reported. This evidence suggests the involvement of some specific SNPs in AHR transcriptional regulation in the process of carcinogenesis or cancer development, but there have been no studies to elucidate the mechanism involved. In this study, we identified the transcription factor Nuclear Factor 1-C (NF1C) as a candidate to regulate AHR transcription in a polymorphism-dependent manner. SNP rs10249788 was included in a consensus binding site for NF1C. Our results suggested that NF1C preferred the C allele to the T allele at rs10249788 for binding. Forced expression of NF1C suppressed the activity of the AHR promoter with C at rs10249788 stronger than that with T. Moreover, expression analysis of human uterine endometrial cancer (HEC) specimens showed greater upregulation of AHR and downregulation of NF1C than those of normal endometrium specimens. Sequence analysis showed HEC patients at advanced stages tended to possess T/T alleles more frequently than healthy women. We also demonstrated that NF1C suppressed proliferation, motility and invasion of HEC cells. This function was at least partially mediated by AHR. This study is the first to report that a polymorphism on the AHR regulatory region affected transcriptional regulation of the AHR gene in vitro. Because NF1C is a tumor suppressor, our new insights into AHR deregulation and its polymorphisms could reveal novel mechanisms of genetic susceptibility to cancer.
