Particulate matter PM2.5 is a class of airborne particles and droplets with sustained high levels in many developing countries. Epidemiological studies have shown the association between sustained high level of PM2.5 and the risk of many diseases in the respiratory system, including lung cancer. However, the precise mechanisms through which PM2.5 induces respiratory diseases are still unclear. In this study, we demonstrated that CD4(+) and CD8(+) T cells following PM2.5 treatment demonstrated significantly elevated mRNA and protein levels of interferon (IFN)-γ, interleukin (IL)-10, IL-17, and IL-21 production...

The incidence of disease relating to nanoparticle exposure has been rising rapidly in recent years, for which there is no effective treatment. Macrophage is suggested to play a crucial role in the development of pulmonary disease. To investigate the changes in macrophage after being stimulated by nanometer silica dust and to explore potential biomarkers and signaling pathways, the gene chip GSE13005 was downloaded from Gene Expression Omnibus database, which contained 21 samples: 3 samples per group and 7 groups in total...

The new synthetically prepared quinolone derivative 7-ethyl 9-ethyl-6-oxo-6,9-dihydro[1,2,5]selenadiazolo [3,4-h]quinoline-7-carboxylate (E2h) showed in our previous study cytotoxic effects towards tumor cells and immunomodulatory activities on RAW 264.7 cell line murine macrophages. E2h may have a potential use as a novel chemotherapeutic agent with immunomodulatory properties and the ability to induce apoptotic death of cancer cells. The aim of the present study was to examine the antiproliferative/cytotoxic activities of E2h on human non-cancer fibroblast BHNF-1 cells and reconstructed human epidermis EpiDerm™...

Long non-coding RNAs play a pivotal role in tumor progression, but their role in cancer cells in the nutrient-starved tumor microenvironment remains unknown. Here, we show that a nutrient starvation-responsive long non-coding RNA, JHDM1D antisense 1 (JHDM1D-AS1), promotes tumorigenesis by regulating angiogenesis in response to nutrient starvation. Expression of JHDM1D-AS1 was increased in cancer cells. In addition, expression of JHDM1D-AS1 was increased in clinical tumor samples compared to that in normal tissue...

Blood transfusion is a clinical replacement therapy with many successes with some benefit and, also, some harm. Cancer is a multifaceted disease potentially associated with the immune system's weakness where the cancerous tumor cells escape from the immune system. Allogeneic blood transfusion, through five major mechanisms including the lymphocyte-T set, myeloid-derived suppressor cells (MDSCs), tumor-associated macrophages (TAMs), natural killer cells (NKCs), and dendritic cells (DCs) can help the recipient's defense mechanisms...

Background/Aims: In inflammatory bowel disease (IBD), repeated bouts of remission and relapse occur in patients and can impose a risk of colitis-associated cancer. We hypothesized that plant extracts of Atractylodes macrocephala (AM) or Taraxacum herba (TH) may be better than sulfasalazine for treating this disease because these extracts can promote additional regeneration. Methods: Murine intestinal epithelial IEC-6 cells were pretreated with AM or TH before a lipopolysaccharide (LPS)-induced challenge...

Growing evidence indicates that adiposity is associated with breast cancer risk and negatively affects breast cancer recurrence and survival, a paracrine role of mammary adipose tissue being very likely in this process. In contrast to other adipose depots, occurrence of a sub-inflammatory state of mammary adipose tissue defined by dying adipocytes surrounded by macrophages forming crown-like structures in overweight and obese subjects, remains only partially described. In a general population of breast cancer patients (107 patients) mostly undergoing breast-conserving surgery, we found a positive association between patient's body composition, breast adipocytes size, and presence of crown-like structures in mammary adipose tissue close to the tumor...

Since its first description in 1966, macrophage migration inhibitory factor (MIF) was found to play a critical role in inflammatory and immune responses as well as in disease pathogenesis especially in tumor pathogenesis and cancer progression. MIF is expressed in different cell types and is associated with many disease severity and tumor pathogenesis. Here, we investigated the influence of TLR7 and TLR8 agonist resiquimod (R848), an immune response inducer used as a prophylactic agent for several infectious diseases as well as anticancer agents and vaccine adjuvant on MIF expression in cells and organs...

The objective of this study was to examine the effect of autophagy on stress-induced M2 macrophage polarization in the tumor microenvironment of breast cancer and to determine whether the underlying mechanism was related to the reactive oxygen species (ROS)/ERK and mTOR pathway. In vitro, we found that the basal autophagy level in mouse RAW 264.7 macrophages decreased with the incubation of tumor cell culture supernatant. Similarly, the polarization of RAW 264.7 to M2 macrophages was inhibited by the autophagy inducer rapamycin and increased by the autophagy inhibitor 3-MA or by siBeclin1...

Bruton's tyrosine kinase (BTK) regulates many vital signaling pathways and play critical role in cell proliferation, survival, migration, and resistance. Earlier we reported that a small molecule KS99 is an inhibitor of tubulin polymerization. In the present study we explored that whether KS99 is a dual inhibitor of BTK and tubulin polymerization. While it is known that BTK is required for clonogenic growth, and resistance; and microtubules are essential for cancer cell growth; dual targeting of these two components has not been explored...

When expressed on the surface of cells, CD47 inhibits phagocytosis of these cells by phagocytes. Most human cancers overexpress CD47, and antibodies to CD47 have shown a remarkable ability to clear a range of cancers in animal models. However, the mechanism by which these antibodies cause cancer cell death is unclear. We find that CD47 is expressed on the surface of three B-cell lines from human malignancies: 697 (pre-B-ALL lymphoblasts), Ramos and DG-75 (both mature B-cells, Burkitt's lymphoma), and anti-CD47 antibodies greatly increase the phagocytosis of all three cell line by macrophages...

INTRODUCTION: Cytokine gene therapy is one of the cancer treatment strategies. Recently, granulocyte-monocyte colony-stimulating factor (GM-CSF), as an important cytokine in activating dendritic cells and boosting the anti-tumor immune responses, has been utilized as an immunotherapeutic agent in cancer gene therapy. The purpose of the present investigation was to study the GM-CSF gene therapy effects in regression of tumor masses in fibrosarcoma mouse model. MATERIALS AND METHODS: To investigate the therapeutic efficacy of GM-CSF, WEHI-164 tumor cells were transfected with murine GM-CSF plasmid...

PURPOSE: Given its extremely poor prognosis, there is a pressing need for an improved understanding of the biology of glioblastoma multiforme (GBM), including the roles of tumor subpopulations that may contribute to their growth rate and therapy resistance. The most malignant phenotypes of GBM have been ascribed to the presence of subpopulations of cancer stem cells (CSCs), which are resistant to chemotherapeutic drugs and ionizing radiation and which promote invasiveness and metastasis...

M2-like tumor-associated macrophages promote breast tumor growth and survival and may migrate into the peripheral blood. However, the frequency of circulating M2-like monocytes in the peripheral blood of breast cancer patients has not been clarified. The objective of this study was to determine the percentages of circulating M2-like monocytes in patients with breast cancer. Immunofluorescence staining for CD68 and CD163 was performed to detect M2-like macrophages in pathological tissues. Flow cytometry was used to assess the frequencies of circulating CD14(+)CD163(+)/CD14(+)CD204(+)/CD14(+)CD163(+)CD204(+) M2-like monocytes in 99 breast cancer patients, 56 patients with benign breast disease, and 60 healthy controls...

Tumor microenvironment (TME) contains a variety of infiltrating immune cells. Among them, tumor-associated macrophages (TAMs) and their alternative activation contribute greatly to the progression of tumors. The mechanisms governing macrophage polarization in the TME are unclear. Here, we show that in TAMs or macrophages under tumor-conditioned medium treatment, the expression of transcription factor EB (TFEB) is reduced and more of the TFEB protein is in an inactive cytosolic form. Transforming growth factor (TGF)-β is identified as a main driving force for the reduced TFEB expression and activity in TAMs via activating ERK signaling...

Nuphar lutea L. SM., leaf and rhizome extracts (NUP), contain nupharidines as active components. Nupharidines belong to the sesquiterpene lactones class of a naturally occurring plant terpenoids. This family of compounds has gained considerable interest for treating infection, inflammation and cancer. NF-κB is a central, downstream regulator of inflammation, cell proliferation and apoptosis. In our previous work we demonstrated strong inhibition of NF-κB activity and induction of apoptosis by NUP. In addition, NUP exhibited anti-inflammatory properties and partial protection from LPS-induced septic shock by modulating ERK pathway and cytokine secretion in macrophages...

The molecular events that promote the development of pulmonary hypertension (PH) are complex and incompletely understood. The complex interplay between the pulmonary vasculature and its immediate microenvironment involving cells of immune system (i.e. macrophages) promotes a persistent inflammatory state, pathological angiogenesis and fibrosis that is driven by metabolic reprogramming of mesenchymal and immune cells. Consistent with previous findings in the field of cancer metabolism, increased glycolytic rates, incomplete glucose and glutamine oxidation to support anabolism and anaplerosis, altered lipid synthesis/oxidation ratios, increased one-carbon metabolism and activation of the pentose phosphate pathway to support nucleoside synthesis are but some of the key metabolic signatures of vascular cells in PH...

Background Clonal hematopoiesis of indeterminate potential (CHIP), which is defined as the presence of an expanded somatic blood-cell clone in persons without other hematologic abnormalities, is common among older persons and is associated with an increased risk of hematologic cancer. We previously found preliminary evidence for an association between CHIP and atherosclerotic cardiovascular disease, but the nature of this association was unclear. Methods We used whole-exome sequencing to detect the presence of CHIP in peripheral-blood cells and associated such presence with coronary heart disease using samples from four case-control studies that together enrolled 4726 participants with coronary heart disease and 3529 controls...
