Abstract
BACKGROUND Osteosarcoma is one of the most common cancers worldwide. Intense efforts have been made to elucidate the pathogeny, but the mechanisms of osteosarcoma are still not well understood. We aimed to investigate the potential biomarker, allograft inflammatory factor-1 (AIF1), affecting the progression and prognosis of osteosarcoma. METHODS Three microarray datasets were downloaded from GEO datasets and one was obtained from the TCGA dataset. The differentially expressed genes (DEGs) were identified. GO and KEGG functional enrichment analyses of overlapped DEGs were performed. The PPI network of overlapped DEGs was constructed by STRING and visualized with Cytoscape. Overall survival (OS) and Metastasis free survival (MFS) were analyzed from GSE21257. Finally, the effect of the most relevant core gene affecting the progression of osteosarcoma was examined in vitro. RESULTS One hundred twenty six DEGs were identified, consisting of 65 upregulated and 61 downregulated genes. Only AIF1 was significantly associated with OS and MFS. It was found that AIF1 could be enriched into the NF-κB signaling pathway. GSEA and ssGSEA analyses showed that AIF1 was associated with the immune invasion of tumors. Cell experiments showed that AIF1 was underexpressed in osteosarcoma cell lines, while the malignant propriety was attenuated after overexpressing the expression of AIF1. Moreover, AIF1 also affects the expression of the NF-κB pathway. CONCLUSION In conclusion, DEGs and hub genes identified in the present study help us understand the molecular mechanisms underlying the carcinogenesis and progression of osteosarcoma, and provide candidate targets for diagnosis and treatment of osteosarcoma.

Abstract
Allograft inflammatory factor-1 (AIF-1) is expressed in microglia. Unilateral common carotid artery occlusion (UCCAO) was conducted to elucidate mechanisms that regulate AIF-1 expression in C57BL/6 male mice. Immunohistochemical reactivity of microglia against anti-AIF-1 antibody was increased significantly in the brain of this model. The increased AIF-1 production was further confirmed by ELISA using brain homogenate. Real-time PCR demonstrated that the increased AIF-1 production was regulated at the transcriptional level. Serum AIF-1 levels were further examined by ELISA and marked increase was observed on Day 1 of UCCAO. To examine the influence of AIF-1, immunohistochemical staining was performed and revealed that the immunoreactivity against anti-Iba-1 antibody was significantly increased in various organs. Among them, the accumulation of Iba-1+ cells were observed prominently in the spleen. Intraperitoneal injection of minocycline, a potent microglia inhibitor, reduced the number of Iba-1+ cells suggesting microglia activation-dependent accumulation. Based on these results, AIF-1 expression was further examined in the murine microglia cell line MG6. AIF-1 mRNA expression and secretion were up-regulated when the cells were cultured under hypoxic condition. Importantly, stimulation of the cells with recombinant AIF-1 induced the expression of AIF-1 mRNA. These results may suggest that increased AIF-1 production by microglia in cerebral ischemia regulate the AIF-1 mRNA expression at least in part by an autocrine manner.

Abstract
Allograft inflammatory factor-1 (AIF-1) is a 17 kDa calcium-binding protein associated with numerous inflammatory diseases. The full-length cDNA of AIF-1 has been identified in grass carp, Ctenopharyngodon idellus in our previous study, and it was assumed to be a novel molecule involved in immune responses. To clarify this aspect, the level of AIF-1 expression was amplified and reduced in grass carp peripheral blood leukocytes via transfection of vector pcDNA3.1-AIF1-EGFP and pLKO.1-shRNA-EGFP-puro, respectively. Thereafter, AIF-1 stimulated cell proliferation, inhibited cell apoptosis, which might benefit from improved mitochondrial function as evidenced by increased mitochondrial membrane potential, subsequently promoted ATP production. In addition, AIF-1 induced leukocyte migration via up-regulated monocyte chemotactic protein-1(MCP-1) secretion, enhanced neutral red uptake into leukocyte, provoked pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-α), interleukin 1β (IL1β), interleukin 6 (IL6), interleukin 8 (IL8) and suppressed anti-inflammatory cytokine interleukin 10 (IL10) production. These results indicated AIF-1 played a critical role in grass carp innate immune system.

Abstract
Allograft inflammatory factor-1 (AIF-1) is a 17 kDa calcium-binding protein produced by monocytes, macrophages, and lymphocytes; its synthesis is induced by INF-γ. The AIF-1 gene is located in the major histocompatibility complex (MHC) class III region on chromosome 6p21.3, surrounded by surface glycoprotein genes and complement cascade protein genes as well as TNF-α, TNF-β, and NF-κB genes. Increased expression of AIF-1 was observed in several diseases, including endometriosis, breast cancer, atherosclerosis, rheumatoid arthritis, and fibrosis. In this review, we summarise the role of AIF-1 in allograft rejection and the pathogenesis of diseases.

Abstract
Recent studies demonstrated that allograft inflammatory factor-1 (AIF-1) and RNASET2 act as chemoattractants for macrophages and modulate the inflammatory processes in both vertebrates and invertebrates. The expression of these proteins significantly increases after bacterial infection; however, the mechanisms by which they regulate the innate immune response are still poorly defined. Here, we evaluate the effect of bacterial lipopolysaccharide injection on the expression pattern of these genes and the interrelation between them during innate immune response in the medicinal leech, an invertebrate model with a simple anatomy and a marked similarity with vertebrates in inflammatory processes. Collectively, prokaryotic-eukaryotic co-cultures and in vivo infection assays suggest that RNASET2 and AIF-1 play a crucial role in orchestrating a functional cross-talk between granulocytes and macrophages in leeches, resulting in the activation of an effective response against pathogen infection. RNASET2, firstly released by granulocytes, likely plays an early antibacterial role. Subsequently, AIF-1+ RNASET2-recruited macrophages further recruit other macrophages to potentiate the antibacterial inflammatory response. These experimental data are in keeping with the notion of RNA-SET2 acting as an alarmin-like molecule whose role is to locally transmit a "danger" signal (such as a bacterial infection) to the innate immune system in order to trigger an appropriate host response.

Abstract
Allograft inflammatory factor-1 (AIF-1) is an inflammation-related protein mainly produced by immune cells, such as monocyte/macrophages and activated T lymphocytes. It is essential for the survival and proinflammatory activity of immune cells. However, the function of AIF-1 in chicken still has not been defined. In the present study, AIF-1-like (AIF1L) gene was identified in Luning chicken. Bioinformatics analysis revealed that the molecular weight of the chicken AIF-1 protein was 16290.8 Da. AIF1L contained a Ca2+ binding EF hand and could interact with actin filament. Its transcript was found in all tested tissues including spleen, brain, heart, kidney, liver, thymus, bursa of Fabricius, lung, and a relative low-level expression was detected in leg muscle. Furthermore, AIF1L expression in peripheral blood lymphocyte was depressed in a dose-dependent manner with cadmium exposure and peripheral blood lymphocyte viability decrease displayed a similar pattern with AIF1L expression. The results indicated that newly identified chicken AIF1L might be associated with lymphocyte viability.

Abstract
BACKGROUND/AIMS Allograft inflammatory factor-1 (AIF-1) is an inflammatory cytokine produced mainly by macrophages within human white adipose tissue. Its expression is increased in obese subjects and positively correlated with insulin resistance. The purpose of this study is to characterize the regulatory role of AIF-1 in insulin signaling of adipocyte. METHODS AIF-1 was over-expressed via transfection of AIF-1 cDNA into murine RAW 264.7 macrophages, and the constitutive expression of AIF-1 was decreased via transfection of targeting siRNA. Murine 3T3L1 adipocytes were treated with macrophage-conditioned medium or AIF-1 protein. Intracellular lipid accumulation was assayed by oil red O stain. Reactive oxygen species production was determinated by a flow cytometer and adipokine secretion was measured with ELISA. Glucose uptake was detected using the glucose oxidase method and insulin-signal-transduction related molecules were analyzed by Western blot. RESULTS Short term (48 h) AIF-1 treatment slightly promoted intracellular lipid storage in differentiating 3T3L1 cells. The protein stimulated reactive oxygen species production, provoked TNFα, IL6, resistin, but suppressed adiponectin release and insulin-stimulated glucose uptake both under normal basal and insulin resistance conditions. Furthermore, AIF-1 induced NF-κB activation, inhibited PPARγ expression, GLUT4 translocation to plasma membrane and Akt phosphorylation. CONCLUSION Macrophage-derived AIF-1 up-regulated reactive oxygen species production, adipokine TNFα, IL6, resistin release, and inhibited adiponectin secretion. Moreover, it suppressed insulin-stimulated glucose uptake by down-regulating insulin signaling. Thus, AIF-1 could be related to obesity-related diseases.

Abstract
Allograft inflammatory factor-1 (AIF-1) is a protein expressed by macrophages infiltrating the area around the coronary arteries in a rat ectopic cardiac allograft model. We previously reported that AIF-1 is associated with the pathogenesis of rheumatoid arthritis and skin fibrosis in sclerodermatous graft-versus-host disease mice. Here, we used an animal model of bleomycin-induced lung fibrosis to analyze the expression of AIF-1 and examine its function in lung fibrosis. The results showed that AIF-1 was expressed on lung tissues, specifically macrophages, from mice with bleomycin-induced lung fibrosis. Recombinant AIF-1 increased the production of TGF-β which plays crucial roles in the mechanism of fibrosis by mouse macrophage cell line RAW264.7. Recombinant AIF-1 also increased both the proliferation and migration of lung fibroblasts compared with control group. These results suggest that AIF-1 plays an important role in the mechanism underlying lung fibrosis, and may provide an attractive new therapeutic target.

Abstract
The allograft inflammatory factor-1 (AIF-1) is one of the key factors associated with inflammatory response and immune defense. In the present study, we report the identification and characterization of AIF-1 from triangle sail mussel Hyriopsis cumingii (HcAIF-1). The full-length cDNA of HcAIF-1 consisted of a 5'-terminal untranslated region (UTR) of 80 bp, a 3'-UTR of 420 bp with a poly (A) tail, and an open reading frame of 444 bp encoding a polypeptide of 147 amino acids with two conserved EF-hand Ca2+-binding motifs. HcAIF-1 mRNA and protein were expressed in all examined tissues and showed higher mRNA expression levels were observed in immune tissues, especially hemocytes and mantle, and the highest protein expression level was in mantle. The expression level of HcAIF-1 mRNA was significantly upregulated in hemocytes 12-48 h after lipopolysaccharide challenge. After mantle tissue implantation, the expression level of this gene in pearl sac decreased significantly at 3-48 h (P < 0.01), and then was significantly upregulated at 96 h (P < 0.05) and recovered to the control level at 21-28 d. There was significant increase HcAIF-1 transcript abundance in hemocytes 96 h (P < 0.05) after mantle tissue implantation. The phagocytosis rate was significantly enhanced in hemocytes 3-24 h (P < 0.01) after the injection of recombinant HcAIF-1 protein. These findings suggest that HcAIF-1 is important in the underlying mechanism of the innate immune responses and pearl sac formation of H. cumingii.

Abstract
OBJECTIVE Allograft inflammatory factor-1 (AIF-1) is a cytoplasmic protein expressed in various human cells such as monocyte/macrophages and activated T lymphocytes. A recent study showed that AIF-1 is strongly expressed in infiltrating mononuclear cells and synovial fibroblasts in rheumatoid arthritis and that AIF-1 induces the proliferation of cultured synovial cells. In this study we analysed the expression of AIF-1 in peripheral blood monocytes and synovial membranes from patients with rheumatoid arthritis (RA). METHODS We examined 71 patients with rheumatoid arthritis and 25 control subjects. RESULTS Using flow cytometry we found significantly increased numbers of circulating AIF-1(+) monocytes in peripheral blood from RA patients compared with controls. Moreover, there were statistically significant positive correlations between AIF-1(+) monocytes, DAS28 and the Sharp erosion score. Immunofluorescence staining showed strong expression of AIF-1 by infiltrating mononuclear cells - predominantly macrophages in RA synovial tissues - compared with tissues derived from joints affected by osteoarthritis. CONCLUSION The results of this study suggest that AIF-1 may be associated with the pathogenesis of RA and may be a novel cytokine involved in the immunological process underlying RA.

Abstract
Allograft Inflammatory Factor-1 (AIF-1) is an inflammation responsive protein that is mainly produced by immunocytes. As a pro-inflammatory cytokine, AIF-1 is a key moderator in host immune defense reaction. However, the inflammatory properties of AIF-1 in freshwater fish still hasn't been clearly elucidated. In the present study, AIF-1 was identified from grass carp (Ctenopharynogodon idella). It's transcript was found in all examined tissues including brain, spleen, kidney, liver, heart, while a relative low level in red muscle, gill, thymus, white muscle, intestine and fin. Furthermore, AIF-1 transcription and expression level decreased in spleen and didn't change a lot in kidney with cadmium induction, respectively. The result indicated that grass carp AIF-1 might be involved in cadmium-induced stress.

Abstract
Allograft inflammatory factor-1 (AIF-1) is an interferon (IFN)-γ-inducible Ca(2+)-binding cytokine that associates with the immune defense and inflammatory response. In this study, we reported AIF-1 gene in sea cucumber Apostichopus japonicus (AjAIF-1). The full-length cDNA of AjAIF-1 is 1541 bp with an open reading frame (ORF) of 477 bp encoding 158 amino acids. Two EF-hand Ca(2+)-binding motifs were found in the deduced AjAIF-1. AjAIF-1 was widely expressed in all tested tissues (body wall, intestine, respiratory tree, tube feet, coelomocytes and longitudinal muscle), with the highest expression in respiratory tree. After Vibrio splendidus challenge and physical injury, AjAIF-1 transcripts were significantly upregulated in coelomocytes. The mRNA expression level of AjAIF-1 in coelomocytes reached to the highest value at 4 h (3.38-folds vs. the PBS control, P < 0.05) post injection. After papilla injury, the mRNA level of AjAIF-1 in coelomocytes was upregulated, and its peak value was found at 4 h (3.88-folds vs. the control, P < 0.05). These results indicated that 1) AjAIF-1 sensitively responds to pathogen infection; 2) AjAIF-1 is involved in acute inflammatory response. Our findings gain general information about the role of AjAIF-1 in the innate immunity of A. japonicus.

Abstract
Allograft inflammatory factor-1 (AIF-1) is expressed by macrophages, fibroblasts, endothelial cells and smooth muscle cells in immune-inflammatory disorders such as systemic sclerosis, rheumatoid arthritis and several vasculopathies. However, its molecular function is not fully understood. In this study, we examined gene expression profiles and induction of chemokines in monocytes treated with recombinant human AIF (rhAIF-1). Using the high-density oligonucleotide microarray technique, we compared mRNA expression profiles of rhAIF-1-stimulated CD14(+) peripheral blood mononuclear cells (CD14(+) PBMCs) derived from healthy volunteers. We demonstrated upregulation of genes for several CC chemokines such as CCL1, CCL2, CCL3, CCL7, and CCL20. Next, using ELISAs, we confirmed that rhAIF-1 promoted the secretion of CCL3/MIP-1α and IL-6 by CD14(+) PBMCs, whereas only small amounts of CCL1, CCL2/MCP-1, CCL7/MCP-3 and CCL20/MIP-3α were secreted. Conditioned media from rhAIF-1stimulated CD14(+) PBMCs resulted in migration of PBMCs. These findings suggest that AIF-1, which induced chemokines and enhanced chemotaxis of monocytes, may represent a molecular target for the therapy of immune-inflammatory disorders.
