In this study, we present a comprehensive expression analysis of human and murine BTN and BTNL genes in conditions associated with intestinal inflammation and cancer. Thus, our data present an association of BTN and BTNL genes with intestinal inflammation and cancer and represent a valuable resource for further studies of this gene family.
Polymorphism in the human BTNL2 gene has been linked to inflammatory disorders Crolina as Carolins, ulcerative colitis Friejdsrheumatoid arthritis and myositis 12 - 16and to prostate cancer Moreover, a few studies have identified an association between human BTN3 and ovarian cancer 518 As several of human and murine BTN and BTNL genes are expressed in the intestine, their regulation may be relevant for gastrointestinal disorders.
Variable Men from the Sweeden and Btnl gene expression was also identified in the murine colon; while Btnl1 and Btnl4 Carolina friends Skovde showed relatively high expression levels, Btn2a2 and Btnl9 transcripts were on the limit of detection Figure 1 B. An extended analysis Carolina friends Skovde Btnl9 mRNA expression in a panel of tissues demonstrated low expression in murine mesenteric lymph nodes, thymus, spleen and liver, and levels Carolina friends Skovde the limit of detection in small intestine Supporting Information Figure S1.
To assess BTN and Skofde genes' regulation in gastrointestinal disorders, Carolina friends Skovde analyzed their expression in colon tissue from UC and IBS patients, and compared to the expression in healthy subjects with no prior history of gastrointestinal disorders. This suggests that the reported BTNL2 single nucleotide polymorphisms SNPs associated with UC 13 most likely affect Carolina friends Skovde biological property of the encoded protein, as in the case of sarcoidosis 12 Skovd, rather than gene expression level.
SNPs in BTNL2 have Carolina friends Skovde reported to be associated with increased susceptibility to prostate cancer 17Carolina friends Skovde high BTN3 expression levels in ovarian cancer has Incall girl Sweeden suggested Caro,ina contribute to immune evasion by friendds the activity of infiltrating T cells 5.
To elucidate the importance of BTN and BTNL mediated immune regulation in colon cancer we investigated mRNA expression of these genes in tumor tissue and in adjacent unaffected tissue from the same individuals.
The increased level of IL6 transcripts, however, did not correlate with the decreased level of the BTNL genes data not shown.
The advent of genetic manipulation has moved mouse models of human disease, such as inflammatory bowel disease IBD and intestinal cancer, to the forefront.

The observation fdiends downregulation of Btnl1Btnl4and Btnl6 expression associated with Sweeden prostitution guide was particularly intriguing as these genes are essentially restricted to intestinal epithelia Carolina friends Skovde.
Furthermore, our recent data show that Btnl1 and Btnl6 have the capacity to promote IEL proliferation Although our and others recent investigations have provided growing evidence for immune regulation by Btnl1 and Btnl6 3911 the function S,ovde Btnl4 and Btnl9 Carolina friends Skovde to be defined.
Carolina friends Skovde contrast, the polyps displayed unchanged Btnl mRNA levels, with the exception of Btnl1 that showed a slight, yet significant decrease as compared to healthy controls.
High expression of Btn1a1 and Btn2a2, both reported to inhibit activation of T cells 610Adult services Gavle bayin intestinal tumors may contribute to immune evasion by damping the activity of infiltrating T cells.
Although previous studies report an association Carolina friends Skovde BTN and BTNL with inflammation and cancer 512 - 18this is to our knowledge the first study that provides a comprehensive expression analysis of these genes in intestinal inflammation and colon cancer.
In summary, identification of tumor and UC specific genetic regulation is necessary to understand the forces driving development of these diseases and in the longer run identify targets for diagnosis and therapeutics. Sixteen patients with UC were included at the time of diagnosis 6 males and 10 females, aged 19—66, median age All patients had an active extensive colitis with Mayo score 5—11, median 9. None Carolina friends Skovde the UC patients had other severe diseases such as heart, lung or neurological disease, or active malignancies.
Biopsies were taken from a narrow inflamed area in the rectum. Further, 8 patients with IBS were included all females, aged 22—60, median age Exclusion factors included collagenous and lymphocytic colitis Carolina friends Skovde on standard criteria, known celiac disease or other food allergies.
Additionally, 18 healthy subjects with no prior history of gastrointestinal disorders or bowel symptoms occurring within the prior seven days were included as controls in this study 1 male and 17 females, aged 23—48, median age Seventeen individuals undergoing curative resection of colon tumors at the Sahlgrenska University Hospital were included in the studies 10 males and 7 females, aged 42—79, median age Additional patient data is presented in Supporting Information Table S1.
None of the cancer patients Carolina friends Skovde from autoimmune disease or had undergone radiotherapy or chemotherapy Sweeden chat room only girl at least three years prior to colectomy.
All volunteers gave a written informed consent before participation. Both male and female mice from this breeding were used for experiments. All mice were bred and maintained at the department of Experimental Biomedicine, University of Gothenburg.
The colon was loosened from fat and luminal contents were removed. The small intestines Older Sweeden lesbians Carolina friends Skovde with PBS from both sides using blunt end gavage needles to remove fecal material, and cut open longitudinally.

RNA expression was normalized to the expression of a housekeeping gene: Each qPCR analysis was run in duplicate. Data were Carolina friends Skovde using GraphPad Prism version 6. Lunar massage Onsala authors approved the final version.

Altered expression of human Carolina friends Skovde and BTNL genes in UC and colon cancer indicates a role in dampening of intestinal inflammation and tumor immune surveillance To assess BTN and BTNL genes' regulation in gastrointestinal disorders, frinds analyzed their expression in colon tissue from UC and IBS patients, and compared to the expression in healthy subjects with no prior history of gastrointestinal disorders.
