BACKGROUND: Long-term exposure to particulate matter (PM) air pollution may increase blood pressure and the risk of hypertension. However, epidemiological evidence is scarce and inconsistent. OBJECTIVES: We investigated the associations between long-term exposure to PM with an aerodynamic diameter <2.5μm (PM2.5), blood pressure, and incident hypertension in a large Taiwanese cohort. METHODS: We studied 361,560 adults ≥18y old from a large cohort who participated in a standard medical examination program during 2001 to 2014...

BACKGROUND: Vemurafenib, a selective inhibitor of BRAF kinase, is approved for the treatment of adult stage IIIc/IV BRAF V600 mutation-positive melanoma. We conducted a phase I, open-label, dose-escalation study in pediatric patients aged 12-17 years with this tumor type (NCT01519323). PROCEDURE: Patients received vemurafenib orally until disease progression. Dose escalation was conducted using a 3 + 3 design. Patients were monitored for dose-limiting toxicities (DLTs) during the first 28 days of treatment to determine the maximum tolerated dose (MTD)...

Several dual-action Tam-Pt(iv) complexes derived from tamoxifen (Tam) and platinum(ii) drugs were designed and synthesized for targeting estrogen receptors (ERs) and DNA. These novel compounds not only exhibited potent cytotoxicity against breast cancer cells, but also reversed the tamoxifen resistance of TamR-MCF-7 cancer cells. Computational docking assays together with cellular uptake data demonstrated that the ER ligand portion of these conjugates plays a targeting role in ER-positive tumor cells and promotes the uptake of platinum via an estrogen receptor-mediated pathway...

Tumor-associated macrophages (TAMs) are correlated with the prognosis of different types of solid tumors and lymphoma, according to many clinical studies. In vitro experiments have demonstrated the roles of these cells in myeloma cell survival, angiogenesis, immunomodulation, drug resistance, and the interaction between malignant myeloma cells and the microenvironment. Here, we investigated the prognostic significance of TAMs in patients with multiple myeloma (MM). We evaluated the polarized functional status of bone marrow infiltrated by TAMs by immunohistochemical staining of CD68, iNOS, and CD163 in 240 patients with MM from January 2009 to December 2014...

Growth factor receptor tyrosine kinase (RTK) pathway activation is a key mechanism for mediating cancer growth, survival, and treatment resistance. Cognate ligands play crucial roles in autocrine or paracrine stimulation of these RTK pathways. Here, we show SEMA3C drives activation of multiple RTKs including EGFR, ErbB2, and MET in a cognate ligand-independent manner via Plexin B1. SEMA3C expression levels increase in castration-resistant prostate cancer (CRPC), where it functions to promote cancer cell growth and resistance to androgen receptor pathway inhibition...

Pevonedistat (TAK-924/MLN4924) is a novel inhibitor of NEDD8-activating enzyme (NAE) with single-agent activity in relapsed/refractory acute myeloid leukemia (AML). We performed a phase 1b study (NCT01814826) of pevonedistat (PEV) with azacitidine (AZA) based on synergistic activity seen preclinically. Primary objectives included safety and tolerability, and secondary objectives included pharmacokinetics (PK) and disease response. Patients ≥60 years with treatment-naïve AML, unfit for standard induction therapy, received PEV 20 or 30 mg/m2 IV on days 1, 3, and 5, combined with fixed-dose AZA (75 mg/m2 IV/SC) on days 1-5, 8, and 9, every 28 days...

The Tobacco Control Scorecard, published in 2004, presented estimates of the effectiveness of different policies on smoking rates. Since its publication, new evidence has emerged. We update the Scorecard to include recent studies of demand-reducing tobacco policies for high-income countries. We include cigarette taxes, smoke-free air laws, media campaigns, comprehensive tobacco control programs, marketing bans, health warnings, and cessation treatment policies. To update the 2004 Scorecard, a narrative review was conducted on reviews and studies published after 2000, with additional focus on 3 policies in which previous evidence was limited: tobacco control programs, graphic health warnings, and marketing bans...

Sihang Han, Jeff P Hamm
Illusory line motion (ILM) refers to perception of motion in a bar that onsets or offsets all at once. When the bar onsets or offsets between two boxes after one of the boxes flashes, the bar appears to shoot out of the flashed box (flashILM). If the bar offsets during the flash, it appears to contract into the flashed box (reverse ILM; rILM). Onset bars do not show rILM. Moreover, rILM and flashILM are not correlated, indicating they are two different illusions. To date, rILM has only been studied using a 50-ms flash where the bar offsets 16...

Tumor-associated macrophages (TAMs) are an important component of leukocyte infiltration in tumors. TAMs can be classified into M1 and M2 phenotypes. In the present study, the expression of CD204, an M2-polarized macrophage receptor, was investigated by immunohistochemistry in the area surrounding TAMs in 101 cases of canine mammary gland tumor (CMT). We examined the relationship between M2-polarized TAMs and malignancy, histological subtype, histological grade, molecular subtype, hormone receptor (HR) status, and clinical obesity indices...

Deoxyschizandrin, a major lignan of Schisandra berries, has been demonstrated to have various biological activities such as antioxidant, hepatoprotective, and antidiabetic effects. However, the anti-cancer effects of deoxyschizandrin are poorly characterized. In the present study, we investigated the anti-cancer effect of deoxyschizandrin on human ovarian cancer cell lines and tumour-associated macrophages (TAMs). Deoxyschizandrin induced G₀/G₁ phase cell cycle arrest and inhibited cyclin E expression in human ovarian cancer cells...

Amongst Indigenous Australians, "cancer" has negative connotations that detrimentally impact upon access to cancer care services. Barriers to accessing cancer services amongst Indigenous Australians are widely reported. In contrast, factors that facilitate this cohort to successfully navigate cancer care services ("enablers") are scarcely reported in the literature. Through qualitative interviews, this article examines factors that assist Indigenous Australians to have positive cancer experiences. Semi-structured interviews were conducted with twelve adult Indigenous oncology patients recruited from a tertiary hospital in Queensland, Australia during 2012-2014...

OBJECTIVE: Women with antiphospholipid antibodies (aPL) are at risk for pregnancy complications associated with poor placentation and placental inflammation. While these antibodies are heterogeneous, some anti-β2 GPI antibodies can activate human first trimester trophoblast TLR4 and NLRP3. The objective of this study was to determine the role of negative regulators of TLR and inflammasome function in aPL-induced trophoblast inflammation. METHODS: Human trophoblast cells were treated with or without anti-β2 GPI aPL or control IgG in the presence or absence of the common TAM receptor ligand, GAS6, or the autophagy inducer, rapamycin...

Background: We hypothesized that immune-infiltrates were associated with superior survival, and examined a primary osteosarcoma tissue microarrays (TMAs) to test this hypothesis. Methods: 129 patients (pts) with localized osteosarcoma treated within protocol ISG-OS1 were included in the study. Clinical characteristics, expression of CD8, CD3, FOXP3, CD20, CD68/CD163 (tumor associated macrophage, TAM), Tia-1 (cytotoxic T cell), CD303 (plasmacytoid dendritic cells: pDC), Arginase-1 (myeloid derived suppressor cells: MDSC), PD-1 on immune-cells (IC), and PD-L1 on tumoral cells (TC) and IC were analysed and correlated with outcome...

BACKGROUND: M2-polarized macrophages are tumor-associated-macrophages (TAMs), which are important contents of tumor-infiltrating immune cells. Toll-like receptor 4 (TLR4) is a molecular biomarker of tumor aggressiveness and poor prognosis. Toll-like receptors (TLRs) have important roles in the immune system and M2-polarized macrophages. However, the effects of TLR4 on M2-polarized macrophages in hepatocellular carcinoma (HCC) are unknown. Here, TLR4 expressed on HCC cells mediates the pro-tumor effects and mechanisms of M2-polarized macrophages...

Accumulating evidence has confirmed that malignant tumors have a complex microenvironment, which consists of a heterogeneous collection of tumor cells and other cell subsets (including the full gamut of immune cells). Tumor-associated macrophages (TAMs), derived from circulating Ly6Chi monocytes, constitute the most substantial fraction of tumor-infiltrating immune cells in nearly all cancer types and contribute to tumor progression, vascularization, metastasis, immunosuppression and therapeutic resistance...

Endocannabinoids (eCBs) are internal lipid mediators recognized by the cannabinoid-1 and -2 receptors (CB1R and CB2R, respectively), which also mediate the different physiological effects of marijuana. The endocannabinoid system, consisting of eCBs, their receptors, and the enzymes involved in their biosynthesis and degradation, is present in a vast number of peripheral organs. In this review we describe the role of the eCB/CB1R system in modulating the metabolism in several peripheral organs. We assess how eCBs, via activating the CB1R, contribute to obesity and regulate food intake...

Human natural killer (NK) cells are divided into two subsets: CD56bright and CD56dim NK cells, which differ in maturation, function and distribution. Mechanisms regulating NK cell functions are not completely understood. Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, that binds to a variety of endogenous and exogenous molecules, and that has recently been shown to modulate the function and differentiation of immune cells. Here, we studied the expression of AhR and its involvement in the regulation of NK cell functions...

EGFR-mutant lung adenocarcinomas (LUAD) display diverse clinical trajectories and are characterized by rapid but short-lived responses to EGFR tyrosine kinase inhibitors (TKIs). Through sequencing of 79 spatially distinct regions from 16 early stage tumors, we show that despite low mutation burdens, EGFR-mutant Asian LUADs unexpectedly exhibit a complex genomic landscape with frequent and early whole-genome doubling, aneuploidy, and high clonal diversity. Multiple truncal alterations, including TP53 mutations and loss of CDKN2A and RB1, converge on cell cycle dysregulation, with late sector-specific high-amplitude amplifications and deletions that potentially beget drug resistant clones...
