Abstract
Background Edible plants can exert anti-inflammatory activities in humans, being potentially useful in the treatment of inflammatory diseases. Plant-derived microRNAs have emerged as cross-kingdom gene expression regulators and could act as bioactive molecules involved in the beneficial effects of some edible plants. We investigated the role of edible plant-derived microRNAs in the modulation of pro-inflammatory human genes. Methods MicroRNAs from plant-derived foods were identified by next-generation sequencing. MicroRNAs with inflammatory putative targets were selected, after performing in silico analyses. The expression of candidate plant-derived miRNAs was analyzed by qPCR in edible plant-derived foods and their effects were evaluated in THP-1 monocytes differentiated to macrophages. The bioavailability of candidate plant miRNAs in humans was evaluated in feces and serum samples by qPCR. Results miR482f and miR482c-5p are present in several edible plant-derived foods, such as fruits, vegetables, and cooked legumes and cereals, and fats and oils. Transfections with miR482f and miR482c-5p mimics decreased the gene expression of CLEC7A and NFAM1, and TRL6, respectively, in human THP-1 monocytes differentiated to macrophages, which had an impact on gene expression profile of inflammatory biomarkers. Both microRNAs (miR482f and miR482c-5p) resisted degradation during digestion and were detected in human feces, although not in serum. Conclusion Our findings suggest that miR482f and miR482c-5p can promote an anti-inflammatory gene expression profile in human macrophages in vitro and their bioavailability in humans can be achieved through diet, but eventually restricted at the gut level.

Abstract
NFAT activating protein with ITAM motif 1 (NFAM1) is an ITAM bearing-transmembrane receptor that has been reported to play a role in B cell signaling and development. We performed expression analysis of NFAM1 using publicly available gene expression data sets and found that NFAM1 expression is significantly induced in intestinal biopsies from Crohn’s disease (CD) and ulcerative colitis (UC) patients. At the cellular level, we further observed high expression of NFAM1 in monocytes and neutrophils, and low expression in B and T cells. To explore the role of NFAM1 in multiple immune cells and its potential role in IBD, we generated NFAM1-/- mice. In contrast with previous reports using NFAM1-transgenic mice, NFAM1-/- mice have no obvious defects in immune cell development, or B cell responses. Interestingly, NFAM1-/- monocytes produce reduced levels of TNF-α in response to activation by multiple IBD-relevant stimuli, including CD40L, TLR ligands and MDP. Additional cytokines and chemokines such as IL-6, IL-12, CCL3 and CCL4 are also reduced in CD40L stimulated NFAM1-/- monocytes. Collectively, these findings indicate that NFAM1 promotes monocyte activation, thereby amplifying the response to diverse stimuli. Similarly, we observed that deletion of NFAM1 in human monocytes reduces expression of CD40L-induced CCL4. Lastly, to assess the role of NFAM1 in IBD, we compared development of anti-CD40 induced colitis in NFAM1+/+ and NFAM1-/- mice. We found that although NFAM1 deletion had no impact on development of gut pathology, we did observe a decrease in serum TNF-α, confirming that NFAM1 promotes pro-inflammatory cytokine production in vivo. Taken together, we conclude that NFAM1 functions to amplify cytokine production and should be further evaluated as a therapeutic target for treatment of autoimmune disease.

Abstract
We have recently demonstrated NFAT activating protein with ITAM motif 1 (NFAM1) signaling increases osteoclast (OCL) formation/bone resorption associated with the Paget's disease of bone, however, the underlying molecular mechanisms of the NFAM1 regulation of OCL differentiation and bone resorption remains unclear. Here, we showed that RANK ligand stimulation enhances NFAM1 expression in preosteoclast cells. Conditioned media collected from RANKL stimulated RAW264.7 NFAM1 knockdown (KD) stable cells showed inhibition of interleukin-6 (2.5-fold), tumour necrosis factor-α (2.2-fold) and CXCL-5 (3-fold) levels compared to wild-type (WT) cells. Further, RANKL stimulation significantly increased p-STAT6 expression (5.5-fold) in WT cells, but no significant effect was observed in NFAM1-KD cells. However, no changes were detected in signal transducer and activator of transcription 3 levels in either of cell groups. Interestingly, NFAM1-KD suppressed the RANKL stimulated c-fos, p-c-Jun and c-Jun N-terminal kinase (JNK) activity in preosteoclasts. We further showed that the suppression of JNK activity is through inhibition of p-SAPK/JNK in these cells. In addition, NFATc1 expression, a critical transcription factor associated with osteoclastogenesis is significantly inhibited in NFAM1-KD preosteoclast cells. Interestingly, NFAM1 inhibition suppressed the OCL differentiation and bone resorption capacity in mouse bone marrow cell cultures. We also demonstrated inhibition of tartrate-resistant acid phosphatase expression in RANKL stimulated NFAM1-KD preosteoclast cells. Thus, our results suggest that NFAM1 control SAPK/JNK signaling to modulate osteoclast differentiation and bone resorption.

Abstract
BACKGROUND AND AIMS Circulating monocytes have been proven to be critical mediators in the propagation and progression of atherosclerosis and myocardial infarction. The present study was designed to characterise a new transmembrane protein-NFAT activating protein with ITAM motif 1 (NFAM1)-on monocytes and uncover the potential effects and underlying mechanisms in coronary artery disease. METHODS Monocytes from a population of four controls, five stable coronary artery disease patients and five acute coronary syndrome patients were isolated for RNA sequencing. A potential monocyte biomarker molecule was discovered and then validated with a group of 79 controls, 70 stable coronary artery disease patients and 183 acute coronary syndrome patients. A stable cell line was generated as an in vitro model to determine chemotaxis migration and chemokine receptor expression. RESULTS NFAM1 was identified through RNA sequencing analysis. The validation results confirmed that NFAM1 expression on monocytes was significantly increased by coronary artery disease status. A higher expression level of NFAM1 on classical and intermediate monocytes was observed compared with that on nonclassical monocytes. As shown in the in vitro cell model, knockdown of NFAM1 significantly attenuated chemotactic migration of monocytes by downregulating chemokine receptor expression and the p38 MAPK signalling pathway. Multivariable regression analysis of a group of 16 individuals suggested that NFAM1 was positively correlated with CCR2 expression. CONCLUSIONS The present study reported for the first time that distinctive alterations of NFAM1 expression on monocytes may correlate with atherosclerosis pathobiology and serve as a potential monocyte biomarker and therapeutic target for coronary artery disease.

Abstract
Introduction Phelan-McDermid syndrome (PMS) is caused by SHANK3 haploinsufficiency. Its wide phenotypic variation is attributed partly to the type and size of 22q13 genomic lesion (deletion, unbalanced translocation, ring chromosome), partly to additional undefined factors. We investigated a child with severe global neurodevelopmental delay (NDD) compatible with her distal 22q13 deletion, complicated by bilateral perisylvian polymicrogyria (BPP) and urticarial rashes, unreported in PMS. Methods Following the cytogenetic and array-comparative genomic hybridization (CGH) detection of a r(22) with SHANK3 deletion and two upstream duplications, whole-genome sequencing (WGS) in blood and whole-exome sequencing (WES) in blood and saliva were performed to highlight potential chromothripsis/chromoanagenesis events and any possible BPP-associated variants, even in low-level mosaicism. Results WGS confirmed the deletion and highlighted inversion and displaced order of eight fragments, three of them duplicated. The microhomology-mediated insertion of partial Alu-elements at one breakpoint junction disrupted the topological associating domain joining NFAM1 to the transcriptional coregulator TCF20. WES failed to detect BPP-associated variants. Conclusions Although we were unable to highlight the molecular basis of BPP, our data suggest that SHANK3 haploinsufficiency and TCF20 misregulation, both associated with intellectual disability, contributed to the patient’s NDD, while NFAM1 interruption likely caused her skin rashes, as previously reported. We provide the first example of chromoanasynthesis in a constitutional ring chromosome and reinforce the growing evidence that chromosomal rearrangements may be more complex than estimated by conventional diagnostic approaches and affect the phenotype by global alteration of the topological chromatin organisation rather than simply by deletion or duplication of dosage-sensitive genes.

Abstract
Paget's disease of bone (PDB) is marked by the focal activity of abnormal osteoclasts (OCLs) with excess bone resorption. We previously detected measles virus nucleocapsid protein (MVNP) transcripts in OCLs from patients with PDB. Also, MVNP stimulates pagetic OCL formation in vitro and in vivo. However, the mechanism by which MVNP induces excess OCLs/bone resorption activity in PDB is unclear. Microarray analysis identified MVNP induction of NFAM1 (NFAT activating protein with ITAM motif 1) expression. Therefore, we hypothesize that MVNP induction of NFAM1 enhances OCL differentiation and bone resorption in PDB. MVNP transduced normal human PBMC showed an increased NFAM1 mRNA expression without RANKL treatment. Further, bone marrow cells from patients with PDB demonstrated elevated levels of NFAM1 mRNA expression. Interestingly, shRNA suppression of NFAM1 inhibits MVNP induced OCL differentiation and bone resorption activity in mouse bone marrow cultures. Live cell widefield fluorescence microscopy analysis revealed that MVNP induced intracellular Ca2+ oscillations and levels were significantly reduced in NFAM1 suppressed preosteoclasts. Further, western blot analysis demonstrates that shRNA against NFAM1 inhibits MVNP stimulated PLCγ, calcineurin, and Syk activation in preosteoclast cells. Furthermore, NFAM1 expression controls NFATc1, a critical transcription factor expression and nuclear translocation in MVNP transuded preosteoclast cells. Thus, our results suggest that MVNP modulation of the NFAM1 signaling axis plays an essential role in pagetic OCL formation and bone resorption activity.

Abstract
Tumor necrosis factor-α (TNF) is a promoter of inflammation. Genes in the TNF pathway include tumor necrosis factor receptor superfamily member 1A (TNFRSF1A), TNF receptor-associated factor 2 (TRAF2), mitogen activated protein kinase 8 (MAPK8), 14 (MAPK14), and mitogen activated protein kinase kinase kinase 7 (MAP3K7), nuclear factor of activated-T-5 (NFAT5) cells and NFAT activated protein with ITAM motif 1 ﹛NFAM1). Data from population-based studies of colon cancer (cases=1,555; controls=1,956) and rectal cancer (cases=754; controls=959) were used. We observed that MAP3K7 rs13208824 was associated with reduced colon cancer risk (OR 0.83, 95% CI 0.71, 0.98 dominant model), TNF rs1800630 was associated with an increased colon cancer risk (OR 1.19 95% CI 1.03, 1.38 for CA/AAvsCC), and TNFRSF1A rs4149570 was associated with reduced risk (OR 0.79 95% CI 0.64, 0.96 TTvsGG). For rectal cancer MAPK8 rs10508901 was associated with increased risk (OR 1.45 95% CI 1.05, 1.99 AA vs CC/CA; NFAT5 (rs12447326 and rs16959025) was associated with a 40% reduced risk for the recessive model. Aspirin/NSAID interacted with MAP3K7 (colon cancer) and with MAPK14, NFAT5, and TRAF2 (rectal cancer); smoking cigarettes interacted with NFAM1 and NFAT2 (colon cancer) and MAPK8, NFAT5, and TNFRSF1A (rectal cancer); BMI interacted with NFAM1 and NFAT5 (colon cancer) and with MAPK8 and TNFRSF1A (rectal cancer). A genotype summary score showed a threefold increased risk of dying with higher mutational load. Although few independent associations were detected, aspirin/NSAID, cigarette smoking, and BMI influenced genes in this pathway. These data suggest pathways through which TNF-signaling operates.
