Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignant tumors of the digestive system, but the mechanisms of its development and progression are unclear. Inflammation is thought to be fundamental to pancreatic cancer development and caffeic acid phenethyl ester (CAPE) is an active component of honey bee resin or propolis with anti-inflammatory and anticancer activities. We investigated the inhibitory effects of CAPE on cell growth and migration induced by human neutrophil elastase (HNE) and report that HNE induced cancer cell migration at low doses and growth at higher doses...

Angiotensin II (AngII)-induced production of inflammatory factors and proliferation in vascular smooth muscle cells (VSMCs) play an important role in the progression of atherosclerotic plaques. Growing evidence has demonstrated that activation of peroxisome proliferator-activated receptor-γ (PPAR-γ) effectively attenuates AngII-induced inflammation and intercellular reactive oxygen species (iROS) production. Curcumin (Cur) inhibits inflammatory responses by enhancing PPAR-γ activity and reducing oxidative stress in various tissues...

Rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are chronic inflammatory rheumatic diseases that affect joints, causing debilitating pain and disability. Adenosine receptors (ARs) play a key role in the mechanism of inflammation, and the activation of A2A and A₃AR subtypes is often associated with a reduction of the inflammatory status. The aim of this study was to investigate the involvement of ARs in patients suffering from early-RA (ERA), RA, AS and PsA. Messenger RNA (mRNA) analysis and saturation binding experiments indicated an upregulation of A2A and A₃ARs in lymphocytes obtained from patients when compared with healthy subjects...

Chronic lymphedema predisposes to develop malignant cutaneous tumors, including angiosarcoma, Kaposi's sarcoma and B cell lymphoma. T cell malignancy has rarely been associated with chronic lymph stasis. Here we report a case of primary cutaneous anaplastic large cell lymphoma (pcALCL) with lymphatic spread associated with chronic lymphedema. The patient is a 56-year-old man who received orchiectomy and right inguinal lymphadenectomy for malignant seminoma 10 years ago, which led to prominent lymphedema of the right leg...

Acute lung injury (ALI) is a deadly symptom for serious lung inflammation. Discoidin Domain Receptor 1 (DDR1) is a new potential target for anti-inflammatory drug discovery. A new selective tetrahydroisoquinoline-7-carboxamide based DDR1 inhibitor 7ae was discovered to tightly bind the DDR1 protein and potently inhibit its kinase function with a Kd value of 2.2 nM and an IC50 value of 6.6 nM, respectively. The compound dose-dependently inhibited lipopolysaccharide (LPS)-induced interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) release in mouse primary peritoneal macrophages (MPMs)...

In addition to antibiotic therapy for treatment of peritonitis, biologics have also been found to exhibit both anti-inflammatory and inflammation-resolving properties. Here, we first developed NF-κB transgenic mice with zymosan-induced acute peritonitis to investigate the effects of a novel anti-Toll-like receptor (TLR)2 antibody (anti-T20). In this mouse model, anti-T20 treatment significantly attenuated the increase of peritoneal NF-κB activity and serum levels of inflammatory cytokines, including monocyte chemoattractant protein (MCP)-1, interleukin (IL)-6 and tumor necrosis factor (TNF)-α, in a dose-dependent manner compared to mice treated with isotype control antibody...

Angiogenesis is an essential process for tissue growth and embryo development. However, inflammation, abnormal wound healing, vascular diseases, and tumor development and progression can result from inappropriate angiogenesis. Lipopolysaccharide (LPS) can activate various cells and alter endothelium function and angiogenesis. This study investigated the underlying molecular events involved in LPS-induced angiogenesis and revealed a novel strategy for controlling abnormal angiogenesis. LPS treatment promoted wound healing and tube formation in human umbilical vein endothelial cell (HUVEC) cultures and induced their expression of miR-146a...

INTRODUCTION: Deep remission, defined as clinical remission with mucosal healing (MH), with anti-tumor necrosis factor (TNF)-α agents is a new target for therapy in Crohn's disease (CD). Provided that the efficacy of infliximab (IFX) for induction of MH in CD has been demonstrated, there are much less data for adalimumab (ADA), and none concerning MH on histopathological examination. AIM: To assess the impact of biological therapy with ADA on both endoscopic and histopathological MH in paediatric patients with CD...

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous subset of cells that expands dramatically in many disease states and can suppress T-cell responses. MDSCs mainly include monocytic and granulocytic subpopulations that can be distinguished in mice by the expression of Ly6G and Ly6C cell surface markers. This identification system has been validated in experimental tumor models, but not in models of inflammation-associated conditions such as sepsis. We challenged growth factor independent 1 transcription repressor green fluorescent protein (Gfi1:GFP) knock-in reporter mice with cecal ligation and puncture surgery and found that CD11b(+)Ly6G(low)Ly6C(high) MDSCs in this sepsis model comprised both monocytic and granulocytic MDSCs...

Antibiotics are always considered for surgical site infection (SSI) in adolescent idiopathic scoliosis (AIS) surgery. However, the use of antibiotics often causes the antibiotic resistance of pathogens and side effects. Thus, it is necessary to explore natural products as drug candidates. Chitin Oligosaccharide (COS) has anti-inflammation and anti-bacteria functions. The effects of COS on surgical infection in AIS surgery were investigated. A total of 312 AIS patients were evenly and randomly assigned into control group (CG, each patient took one-gram alternative Azithromycin/Erythromycin/Cloxacillin/Aztreonam/Ceftazidime or combined daily), experiment group (EG, each patient took 20 mg COS and half-dose antibiotics daily), and placebo group (PG, each patient took 20 mg placebo and half-dose antibiotics daily)...

Glycogen storage disease type Ia (GSD-Ia) is characterized by impaired glucose homeostasis and long-term risks of hepatocellular adenoma (HCA) and carcinoma (HCC). We have shown that the non-tumor-bearing (NT), recombinant adeno-associated virus (rAAV) vector-treated GSD-Ia mice (AAV-NT mice) expressing a wide range (0.9-63%) of normal hepatic glucose-6-phosphatase-α activity maintain glucose homeostasis and display physiologic features mimicking animals living under calorie restriction (CR). We now show that in AAV-NT mice, the signaling pathways of the CR mediators, AMP-activated protein kinase (AMPK) and sirtuin-1 are activated...
