In vivo models of Inflammatory Bowel Diseases (IBD) elucidate important mechanisms of chronic inflammation. Complex intestinal responses to food components create a unique "fingerprint" discriminating health from disease. Five-week-old IL10(-/-) and C57BL/6J (C57; control) mice were inoculated orally with complex intestinal microflora (CIF) and/or pure cultures of Enterococcus faecalis and E. faecalis (EF) aiming for more consistent inflammation of the intestinal mucosa. Inoculation treatments were compared to non-inoculated IL10(-/-) and C57 mice, either kept in specific pathogen free (SPF) or conventional conditions (2x5 factorial design). At 12 weeks of age, mice were sacrificed for intestinal histological (HIS) and transcriptomic analysis using limma and Ingenuity Pathway Analysis Software. Colonic HIS was significantly affected (P<0.05) in inoculated IL10(-/-) mice and accounted for approximately 60% of total intestinal HIS. Inoculation showed a strong effect on colonic gene expression, with more than 2000 genes differentially expressed in EF.CIF-inoculated IL10(-/-) mice. Immune response gene expression was altered (P<0.05) in these mice. The second study investigated the effect of arachidonic (AA) and eicosapentaenoic acid (EPA) on colonic HIS and gene expression to test whether EPA, contrary to AA, diminished intestinal inflammation in EF.CIF IL10(-/-) mice (2 x 4 factorial design). AIN-76A (5% corn oil) and AIN-76A (fat-free) +1% corn oil supplemented with either 3.7% oleic acid (OA), AA or EPA were used. IL10(-/-) mice fed EPA- and AA-enriched diets had at least 40% lower colonic HIS (P<0.05) than those fed control diets (AIN-76A and OA diets). The expression of immune response and 'inflammatory disease' genes (down-regulated: TNFalpha, IL6, S100A8, FGF7, PTGS2; up-regulated: PPARalpha, MGLL, MYLK, PPSS23, ABCB4 with EPA and/or AA) was affected in IL10(-/-) mice fed EPA- and AA-enriched diets, compared to those fed AIN-76A diet.

Establishment of implantation in pig is accompanied by a coordinated interaction between the maternal uterine endometrium and conceptus development. We investigated the expression profiles of endometrial tissue on Days 9, 12 and 15 of pregnancy and on Day 12 of non-pregnancy in Yorkshire, and performed a comprehensive analysis of long non-coding RNAs (lncRNAs) in endometrial tissue samples by using RNA sequencing. As a result, 2805 novel lncRNAs, 2,376 (301 lncRNA and 2075 mRNA) differentially expressed genes (DEGs) and 2149 novel transcripts were obtained by pairwise comparison. In agreement with previous reports, lncRNAs shared similar characteristics, such as shorter in length, lower in exon number, lower at expression level and less conserved than protein coding transcripts. Bioinformatics analysis showed that DEGs were involved in protein binding, cellular process, immune system process and enriched in focal adhesion, Jak-STAT, FoxO and MAPK signaling pathway. We also found that lncRNAs TCONS_01729386 and TCONS_01325501 may play a vital role in embryo pre-implantation. Furthermore, the expression of FGF7, NMB, COL5A3, S100A8 and PPP1R3D genes were significantly up-regulated at the time of maternal recognition of pregnancy (Day 12 of pregnancy). Our results first identified the characterization and expression profile of lncRNAs in pig endometrium during pre-implantation phases.
