Histone deacetylase 6 (HDAC6) inhibition has been reported to protect against ischemic stroke and prolong survival after sepsis in animal models. However, it remains unknown whether HDAC6 inhibition offers a renoprotective effect after acute kidney injury (AKI). In this study, we examined the therapeutic effect of tubastatin A (TA), a highly selective inhibitor of HDAC6, on AKI in a murine model of glycerol (GL) injection-induced rhabdomyolysis. Following GL injection, the mice developed severe acute tubular injury as indicated by renal dysfunction, expression of neutrophil gelatinase-associated lipocalin (NGAL), an injury marker of renal tubules and increase of TUNEL positive tubular cells...

The research aims to examine the prognostic value of the lymphocyte-to-monocyte ratio (LMR), neutrophil-to- lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in diffuse large B-cell lymphoma (DLBCL). The relation of these hematologic indicators to poor antitumor immunity and prognosis must be investigated. Clinicopathologic data and survival information of 355 patients with DLBCL was retrospectively analyzed. Univariate analysis revealed that lower LMR (<2.71), higher NLR (≥2.81), CD163+ M2 tumor-associated macrophages (TAM) content ≥9...

Inflammation following hemorrhagic shock/resuscitation (HS/RES) induces acute lung injury (ALI). Dimethyl sulfoxide (DMSO) possesses anti-inflammatory and antioxidative capacities. We sought to clarify whether DMSO could attenuate ALI induced by HS/RES. Male Sprague-Dawley rats were allocated to receive either a sham operation, sham plus DMSO, HS/RES, or HS/RES plus DMSO, and these were denoted as the Sham, Sham + DMSO, HS/RES, or HS/RES + DMSO group, respectively (n = 12 in each group). HS/RES was achieved by drawing blood to lower mean arterial pressure (40-45 mmHg for 60 min) followed by reinfusion with shed blood/saline mixtures...

BACKGROUND: Poncirin (PO) and isosakuranetin (or ponciretin [PT]) are compounds found in fruits of the genus Citrus. They are frequently used in traditional Chinese medicine for the treatment of inflammation and asthma. Therefore, we examined their anti-gastritis effects in vitro and in vivo. METHODS: The anti-inflammatory effects of PO and PT were examined using ethanol- or LPS-stimulated KATO III cells. Gastritis was induced in ICR mice via intragastric injection of absolute ethanol...

Increased levels of myeloid cells, especially myeloid-derived suppressor cells (MDSCs), have been reported to correlate with bad prognosis and reduced survival in cancer patients. However, limited data are available on their conclusive phenotypes and their correlation with clinical settings. The aim of this study was to investigate levels and phenotype of myeloid cells in peripheral blood and tumor microenvironment (TME) of colorectal cancer (CRC) patients, compared to blood from healthy donors (HDs) and paired, adjacent non-tumor colon tissue...

Pulmonary fibrosis is a progressive and fatal lung disease with limited therapeutic options. Although it is well known that lipid mediator prostaglandins are involved in the development of pulmonary fibrosis, the role of prostaglandin D2 (PGD2) remains unknown. Here, we investigated whether genetic disruption of hematopoietic PGD synthase (H-PGDS) affects the bleomycin-induced lung inflammation and pulmonary fibrosis in mouse. Compared with H-PGDS naïve (WT) mice, H-PGDS-deficient mice (H-PGDS-/-) represented increased collagen deposition in lungs 14 days after the bleomycin injection...

BACKGROUND: Langerhans cells (LCs) are epidermis-resident dendritic cells that sense and mediate stimuli from skin and outside world, and participate in various skin diseases, playing either pro-inflammatory or regulatory roles. However, the exact function of LCs in the pathogenesis of psoriasis remains unclear, and the conclusions of previous studies are controversial. OBJECTIVES: To explore the role of LCs in mouse model of imiquimod (IMQ)-induced psoriasis-like dermatitis using langerin-diphtheria toxin A (DTA) mice that are constitutively deficient in LCs...

Myeloid-derived suppressor cells (MDSCs) cause paraneoplastic leukemoid reactions and facilitate tumor cell metastasis. However, the interaction of MDSCs with tumor cells in live tissues has not been adequately visualized. To accomplish this task, we developed an intravital imaging protocol to observe metastasized tumor cells in mouse lungs. For visualization of the activation of MDSCs, bone marrow cells derived from transgenic mice expressing a Förster resonance energy transfer (FRET) biosensor for extracellular signal-regulated kinase (ERK) were implanted into host mice...

Inflammation is a significant risk factor for colon cancer. Recent work has demonstrated essential roles for several infiltrating immune populations in the metaplastic progression following inflammation. Hypoxia and stabilization of hypoxia-inducible factors (HIFs) are hallmark features of inflammation and solid tumors. Previously, we demonstrated an important role for tumor epithelial HIF-2α in colon tumors, however, the function of epithelial HIF-2α as a critical link in the progression of inflammation to cancer has not been elucidated...

Solid tumor metastasis is a complex biology, impinged upon by a variety of dysregulated signaling pathways. PI3'-lipid signaling has been associated with metastasis and inflammation in many cancers, but the relationship between tumor cell-intrinsic PI3'-lipid signaling and inflammatory cell recruitment has remained enigmatic. Elevated PI3'-lipid signaling associates with progression of synovial sarcoma, a deadly soft tissue malignancy initiated by a t(X;18) chromosomal translocation that generates an SS18-SSX fusion oncoprotein...

Interleukin 23 (IL-23) is an inflammatory cytokine which plays a vital role in autoimmune diseases as well as in tumorigenesis. However, the role of IL-23 in tumor procession is still controversial and the underlying mechanism remains unclear. Here we established a stable cell line overexpressing IL-23 to prove that IL-23 promoted tumor growth and pulmonary metastasis through induction of tumor-related inflammation and absence of immune surveillance. IL-23 promotes tumor-associate inflammatory response such as infiltration of M2 macrophages, neutrophils and their elevated secretions of immunosuppressive cytokines transforming growth factor-β (TGF-β), IL-10 and vascular endothelial growth factor (VEGF) into tumor tissues, meanwhile the increase of the matrix metalloprotease MMP9...

In the previous work, we have indicated that HMGB1, a pro-inflammatory cytokine, is closely associated with the pathogenesis of psoriasis. To further clarify the role of HMGB1 in the pathogenesis of psoriasis, we investigated the direct function of HMGB1 application and HMGB1 blockade in imiquimod (IMQ)-induced psoriatic mouse model in this study. Mice were treated with imiquimod (IMQ) to induce psoriasis-like inflammation, and consecutively injected with recombinant HMGB1 or phosphate-buffered saline (PBS) i...

OBJECTIVES: We showed previously that stromal cell-derived factor 1 (SDF-1) is a substrate of cluster of differentiation 26/dipeptidylpeptidase 4 (CD26/DPP4) and exerts regenerative properties on acute lung ischemia-reperfusion injury on CD26/DPP4 inhibition. Here, we extend our studies to test whether an intermediate recovery of lung transplants from ischemia/reperfusion injury by CD26/DPP4 inhibition can be achieved for up to 14 days. METHODS: Syngeneic mouse lung transplantation (Tx) was performed in C57BL/6 and in CD26-/- mice by applying 18 hours of cold ischemia...

Proteolytic cascades are deeply involved in critical stages of cancer progression. During the course of peptide-wise analysis of shotgun proteomic datasets representative of colon adenocarcinoma (AC) and ulcerative colitis (UC), we detected a cancer-specific proteolytic fingerprint composed of a set of numerous protein fragments cleaved C-terminally to V, I, A, T, or C residues, significantly overrepresented in AC. A peptide set linked by a common VIATC cleavage consensus was the only prominent cancer-specific proteolytic fingerprint detected...

Tumor infiltrating neutrophils have been implicated in malignant development and progression but mechanisms are ill-defined. Neutrophils produce a proliferation-inducing ligand APRIL/TNFSF13, a factor that promotes development of tumors from diverse origins, including diffuse large B-cell lymphoma (DLBCL). High APRIL expression in DLBCL correlates with reduced patient survival, but the pathway(s) dictating APRIL expression are not known. Here we show that all blood neutrophils constitutively secrete APRIL, and inflammation-associated stimuli such as TNF further upregulate APRIL...

Indoleamine 2,3-dioxygenase (IDO) is a rate limiting enzyme in tryptophan-degrading pathways and IDO activity results in immune suppression. Targeting IDO is a strategy of cancer immunotherapies. Our previous studies demonstrate that delivery of short hairpin against IDO (IDO shRNA) suppresses tumor growth and increases neutrophils infiltration into tumor. Neutrophils reveal antitumorigenic "N1" or protumorigenic "N2" phenotype in tumor microenvironment. However, the function of IDO shRNA-induced neutrophils is not clear...

Therapeutic strategies that act by eliciting and enhancing antitumor immunity have been clinically validated as an effective treatment modality but may benefit from the induction of both cell death and immune activation as primary stimuli. Using our AdRGD-PG adenovector platform, we show here for the first time that in situ gene transfer of p19Arf and interferon-β (IFNβ) in the LLC1 mouse model of lung carcinoma acts as an immunotherapy. Although p19Arf is sufficient to induce cell death, only its pairing with IFNβ significantly induced markers of immunogenic cell death...
