BACKGROUND: Tumor-associated macrophages (TAMs) play a critical role in modulating the tumor microenvironment and promote tumor metastases. Our studies have demonstrated that ginsenoside Rh2 (G-Rh2), a monomeric compound extracted from ginseng, is a promising anti-tumor agent in lung cancer cells. However, it remains unclear whetherG-Rh2 can modulate the differentiation of TAMs and its interaction with tumor microenvironment. In this study, we investigated how G-Rh2 regulates the phenotype of macrophages and affects the migration of non-small cell lung cancer (NSCLC) cells...

Small cell lung cancer (SCLC) represents the most aggressive pulmonary neoplasm and is often diagnosed at late stage with limited survival, despite combined chemotherapies. We show in an autochthonous mouse model of SCLC that combined anti-VEGF/anti-PD-L1 targeted therapy synergistically improves treatment outcome compared to anti-PD-L1 and anti-VEGF monotherapy. Mice treated with anti-PD-L1 alone relapsed after 3 weeks and were associated with a tumor-associated PD-1/TIM-3 double positive exhausted T cell phenotype...

The self-tumor targeting polymers, lactoferrin (LF) and hyaluronic acid (HA) were utilized to develop layer-by-layer (LbL) lipid nanoparticles (NPs) for dual delivery of berberine (BER) and rapamycin (RAP) to lung cancer. To control its release from the NPs, BER was hydrophobically ion paired with SLS prior to incorporation into NPs. Spherical HA/LF-LbL-RAP-BER/SLS-NPs 250.5 nm in diameter, with a surface charge of -18.5 mV were successfully elaborated. The NPs exhibited sequential release pattern with faster release of BER followed by controlled release of RAP which enables sensitization of lung tumor cells to the anti-cancer action of RAP...

Metastatic colorectal cancer still remains an essentially non curable disease. However, with advances in chemotherapeutic and personalizing therapeutic approaches with the incorporation of targeted therapy such as anti-EGFR and anti-VEGF agents survival associated with metastatic colorectal cancer has certainly improved over the last two decades. Patients who are not amenable to surgery median survival remain approximately 2 to 3 years. In an attempt to improve prognostic outcome over the last decade research has focused on therapeutic options geared towards harnessing the immune system with success observed with the use of immune checkpoint inhibitors in the realm of a number of solid tumors including lung and renal cancer...

BACKGROUND Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have been widely used in the treatment of non-small cell lung cancer (NSCLC) patients with sensitive EGFR mutations. However, the survival of patients with EGFR-TKI administration is limited by the inevitable development of acquired drug resistance. Recently, multi-targeted drugs combination has been shown to be a promising strategy to improve the efficacy of EGFR-TKI treatment and enable the reduction of drug resistance in NSCLC...

NK cells are effector lymphocytes involved in tumor immunosurveillance; however, in patients with solid malignancies, NK cells have compromised functions. We have previously reported that lung tumor-associated NK cells (TANKs; peripheral blood) and tumor-infiltrating NK cells (TINKs) show proangiogenic, decidual NK-like (dNK) phenotype. In this study, we functionally and molecularly investigated TINKs and TANKs from blood and tissue samples of patients with colorectal cancer (CRC), a neoplasm in which inflammation and angiogenesis have clinical relevance, and compared them to NK cells from controls and patients with nononcologic inflammatory bowel disease...

Angiogenesis plays a critical role in tumor aggressiveness, and a lot of anti-angiogenic agents have been used in clinical therapy. The therapeutic efficacy of peptides are generally restricted by the short in vivo life-time, thus, we were interested in developing a novel albumin-based and maleimidopropionic acid-conjugated peptide to prolong the half-life and improve the anti-tumor effect. Methods: We developed a peptide F56 with a maleimidopropionic acid (MPA) at the C-terminal (denoted as F56-CM), which allows immediate and irreversible conjugation with serum albumin...

Introduction: Thalidomide (THA) is an angiogenesis inhibitor and an efficient inhibitor of the tumor necrosis factor-α (TNF-α). However, the clinical application of THA has been limited due to hydrophobicity of the compound. Materials and methods: To increase the water solubility of THA and in order to evaluate the anticancer abilities of this material on human lung carcinoma, methoxy poly(ethylene glycol)-poly(ε-caprolactone) nanoparticles loaded with THA (THA-NPs) were prepared...

Polysaccharide (EPS1-1) extracted from fermentation liquor of Rhizopus nigricans possesses antitumor and immune-enhancing activities. The study was the first to investigate the anti-metastasis effects of EPS1-1 in vitro and in vivo. Results suggested that EPS1-1 dose-dependently suppressed the migration, invasion and adhesion abilities of CT26 cells. Furthermore, EPS1-1 dramatically inhibited the enzyme activity and expression levels of matrix metalloproteinases (MMPs) in CT26 cells, as well as the tube formation of HUVECs...

The growth of cancer metastases in the liver depends on a permissive interaction with the hepatic microenvironment and neutrophils can contribute to this interaction, either positively or negatively, depending on their phenotype. Here we investigated the role of IGF-I in the control of the tumor microenvironment in the liver, using mice with a conditional, liver-specific, IGF-I deficiency (iLID) induced by a single tamoxifen injection. In mice that had a sustained (3 weeks) IGF-I deficiency prior to the intrasplenic/portal inoculation of colon carcinoma MC-38 cells, we observed an increase in neutrophil accumulation in the liver relative to controls...

PURPOSE: Ablative hypofractionated radiation therapy (AHFRT) presents a therapeutic advantage compared with conventional fractionated radiation therapy (CFRT) for primary and oligometastatic cancers. However, the underlying mechanisms remain largely unknown. In the present study, we compared the immune alterations in response to AHFRT versus CFRT and examined the significance of immune regulations contributing to the efficacy of AHFRT. METHODS AND MATERIALS: We established subcutaneous tumors using syngeneic lung cancer and melanoma cells in both immunocompetent and immunocompromised mice and treated them with AHFRT and CFRT under the same biologically equivalent dose...

Epithelial-mesenchymal transition (EMT) is associated with tumor invasion and metastasis, and offers insight into novel strategies for cancer treatment. Sotetsuflavone was isolated from Cycas revolute , which has excellent anticancer activity in the early stages. The present study aims to evaluate the anti-metastatic potential of sotetsuflavone in vitro. Our data demonstrated that sotetsuflavone inhibits metastasis of A549 cells, and EMT. This inhibition was reflected in the upregulation of E-cadherin, and downregulation of N-cadherin, vimentin, and Snail...

Angiogenesis and its role in the growth and development of non-small cell lung cancer (NSCLC) metastases has become an increasing clinical problem. Vascular endothelial growth factor (VEGF) plays a key role in advanced NSCLC. To some extent, anti-angiogenic therapies acquired some efficacy in combination with chemotherapy, target therapy and immunotherapy. However, the reliable clinical benefit obtained with these drugs is still questionable and often quantitatively limited. In this review, the authors highlight the data obtained from first-line, second-line, epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI) target therapy and immunotherapy in NSCLC patients who are treated with anti-angiogenic molecules in advanced NSCLC...

Avemar, a derivative of fermented wheat germ extract, is a non-toxic and natural compound that is used as a dietary supplement by cancer patients undergoing chemotherapy and radiotherapy. Avemar has numerous biological activities, and several recent studies have reported that it may also have metastatic and anti-angiogenic effects. In the present study, the mechanism of the anti-angiogenic effect of Avemar on human cancer cells was investigated. The human cell lines NCI-N87 (gastric tubular adenocarcinoma), PC3 (prostate carcinoma), HeLa (endocervical adenocarcinoma) and A549 (lung adenocarcinoma) were treated with various doses (400, 800, 1,600 and 3,200 µg/ml) of Avemar, and the changes in mRNA and protein levels of two important markers of angiogenesis, vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (Cox-2), were assessed by reverse transcription-quantitative polymerase chain reaction and ELISA...

Non-small cell lung carcinoma (NSCLC) is the most common cause of cancer‑associated mortality in the world and accounts for ~85% of human lung cancers. Metastasis‑associated protein 2 (MTA2) is a component of the histone deacetylase complex and serves a role in tumor progression; however, the mechanism through which MTA2 is involved in the progression of NSCLC remains unclear. The aim of the present study was to investigate the expression and function of MTA2 and the MTA2‑mediated signaling pathway in NSCLC cells...
