S100A8 and S100A9 are calcium-binding proteins predominantly expressed by neutrophils and monocytes, and play key roles in both normal and pathological inflammation. Recently, both proteins were found to promote tumor progression through the establishment of pre-metastatic niches and to inhibit antitumor immune responses. Although S100A8 and S100A9 have been studied in solid cancers, their functions in hematological malignancies remain poorly understood. However, S100A8 and S100A9 are highly expressed in acute myeloid leukemia (AML), and S100A8 expression has been linked to a poor prognosis in AML...

Calgranulin genes (S100A8, S100A9 and S100A12) play key immune response roles in inflammatory disorders, including cardiovascular disease. Long-chain omega-3 polyunsaturated fatty acids (LC n-3 PUFA) may have systemic and adipose tissue-specific anti-inflammatory and cardio-protective action. Interactions between calgranulins and the unsaturated fatty acid arachidonic acid (AA) have been reported, yet little is known about the relationship between calgranulins and the LC n-3 PUFA eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)...

Spontaneous tumor regression, regression in the absence of therapeutic intervention, can be identified histologically in over 25% of primary cutaneous melanomas at initial diagnosis. A unique subset of T lymphocytes found in areas of regression can be histologically distinguished from tumor-infiltrating T lymphocytes (TIL) found in areas of tumor progression. We call this unique subset of T lymphocytes regression-associated T lymphocytes (RATs). The aim of this study is to determine the phenotype of lymphocytes and the density of specific cell types linked to immunosuppression in areas of tumor progression compared with areas of tumor regression...

Aberrant chromobox (CBX) family protein expression has been reported in a variety of human malignancies. However, the role of CBX6 in hepatocellular carcinoma (HCC) progression and patient prognosis remains unknown. In this study, we found that CBX6 was frequently up-regulated in HCC clinical samples and HCC cell lines and that CBX6 expression was significantly correlated with larger tumor sizes (≥ 5 cm, p = 0.011) and multiple tumors (n ≥ 2, p = 0.018). Survival analyses indicated that patients with higher CBX6 expression levels had significantly shorter recurrence-free survival (RFS) and overall survival (OS) than patients with lower CBX6 expression levels, and multivariate analyses confirmed that increased CBX6 expression was an independent unfavorable prognostic factor for HCC patients...

The anti-microbial compound triclosan is incorporated into numerous consumer products and is detectable in the urine of 75% of the general United States population. Recent epidemiological studies report positive associations with urinary triclosan levels and allergic disease. Although not sensitizing, earlier studies previously found that repeated topical application of triclosan augments the allergic response to ovalbumin (OVA) though a thymic stromal lymphopoietin (TSLP) pathway in mice. In the present study, early immunological effects following triclosan exposure were further evaluated following topical application in a murine model...

: ᅟ: Matrix metalloproteinases can modulate the inflammatory response through processing of cyto- and chemokines. Among them, MMP-14 is a non-dispensable collagenase responsible for the activation of other enzymes, triggering a proteolytic cascade. To identify the role of MMP-14 during the pro-inflammatory response, wildtype and Mmp14 (-/-) mice were challenged with lipopolysaccharide. MMP-14 levels decreased after endotoxemia. Mutant animals showed 100% mortality, compared to 50% in wildtype mice...

We recently reported that the accumulation of myeloid-derived suppressor cells (MDSC), defined as CD33(+)HLA-DR(-)Lin(-), plays a direct role in the pathogenesis of myelodysplastic syndrome (MDS). In particular, CD33 is strongly expressed in MDSC isolated from patients with MDS where it plays an important role in MDSC-mediated hematopoietic suppressive function through its activation by S100A9. Therefore, we tested whether blocking this interaction with a fully human, Fc-engineered monoclonal antibody against CD33 (BI 836858) suppresses CD33-mediated signal transduction and improves the bone marrow microenvironment in MDS...

Accumulation of myeloid-derived suppressor cells (MDSCs) is one of the major obstacles against achieving appropriate anti-tumor immune responses and successful tumor immunotherapy. Granulocytic MDSCs (G-MDSCs) are common in tumor-bearing hosts. However, the mechanisms regulating the development of MDSCs, especially G-MDSCs, remain poorly understood. In this report, we showed that interferon regulatory factor 7 (IRF7) plays an important role in the development of G-MDSCs, but not monocytic MDSCs. IRF7 deficiency caused significant elevation of G-MDSCs, and therefore enhanced tumor growth and metastasis in mice...

S100A8 and S100A9 are myeloid cell-derived proteins that are elevated in several types of inflammatory lung disorders. Pro- and anti-inflammatory properties are reported and these proteins are proposed to activate TLR4. S100A8 and S100A9 can function separately, likely through distinct receptors but a systematic comparison of their effects in vivo are limited. Here we assess inflammation in murine lung following S100A9 and S100A8/A9 inhalation. Unlike S100A8, S100A9 promoted mild neutrophil and lymphocyte influx, possibly mediated in part, by increased mast cell degranulation and selective upregulation of some chemokine genes, particularly CXCL-10...

S100A9, a calcium-binding protein, participates in the inflammatory process and development of various tumors, thus attracting much attention in the field of cancer biology. This study aimed to investigate the regulatory mechanism of S100A9 and its function involvement in APL. We used real-time quantitative PCR to determine whether PML/RARα affects the expression of S100A9 in NB4 and PR9 cells upon ATRA treatment. ChIP-based PCR and dual-luciferase reporter assay system were used to detect how PML/RARα and PU...

S100 family genes encode low molecular weight, acidic-Ca(2+) binding proteins implicating in a wide spectrum of biological processes. S100 family contains at least 20 members, most of which are frequently dysregulated in human malignancies including breast cancer. However, the prognostic roles of each individual S100, especially the mRNA level, in breast cancer patients remain elusive. In the current study, we used "The Kaplan-Meier plotter" (KM plotter) database to investigate the prognostic values of S100 mRNA expression in breast cancer...

BACKGROUND: Olmsted syndrome (OS) is a congenital dermatosis characterized by palmoplantar keratoderma and periorificial keratotic plaque. TRPV3 (transient receptor potential vanilloid subtype 3) encodes a thermosensitive Ca(2+) channel and is the causative gene of OS. However, the molecular mechanism that causes the pathological development of OS is unclear. OBJECTIVE: We aimed to investigate the molecular mechanisms underlying OS pathology from the perspective of lipid metabolism...
