BACKGROUND In osteosarcoma, the presence of tumor-infiltrating macrophages positively correlates with patient survival in contrast to the negative effect of tumor-associated macrophages in patients with other tumors. Liposome-encapsulated muramyl tripeptide (L-MTP-PE) has been introduced in the treatment of osteosarcoma patients, which may enhance the potential anti-tumor activity of macrophage...

Background: Ligustrazine, active ingredients extracted from the natural herb Ligusticum Chuanxiong Hort, has promising anti-tumor properties on tumor cell lines. However, potential activity of ligustrazine colorectal cancer (CRC) cells and molecular mechanisms have not been elucidated. In this study, we explored critical functions SW480 CT26 at cellular levels.

Like the anti-angiogenic strategy, anti-vascular mimicry is considered as a novel targeting strategy for glioma. In the present study, we used NGR as a targeting ligand and prepared NGR-modified liposomes containing combretastatin A4 (NGR-SSL-CA4) in order to evaluate their potential targeting of glioma tumor cells and vasculogenic mimicry (VM) formed by glioma cells as well as their anti-VM ac...

objective: gelatinases are a large group of proteolytic enzymes that belong to the matrix metalloproteinases (mmps). mmps are a broad family of peptidases, which proteolyse the extracellular matrix and have an important role in inflammation. verapamil is a calcium channel blocker extensively used in the treatment of numerous cardiovascular diseases such as arrhythmia and hypertension. the anti-...

Tumor-associated macrophages (TAMs) frequently help to sustain tumor growth and mediate immune suppression in the tumor microenvironment (TME). Here, we identified a subset of iron-loaded, pro-inflammatory TAMs localized in hemorrhagic areas of the TME. The occurrence of iron-loaded TAMs (iTAMs) correlated with reduced tumor size in patients with non-small cell lung cancer. Ex vivo experiments ...

Abstract CAR-T cell therapy targeting CD19 demonstrated strong activity against advanced B leukemia, however shows less efficacy lymphoma with nodal dissemination. To target both Non-Hodgkin’s (B-NHLs) and follicular T helper (Tfh) cells in the tumor microenvironment (TME), we apply here a chimeric antigen receptor (CAR) that recognizes human CXCR5 high avidity. CXCR5, physiologically expressed...

Background and objectives: Angiogenesis is essential for tumor survival. Inhibiting angiogenesis could be a mechanism for hindering tumor development. Numerous studies have now been focused on agiogenesis inhibitors and many of such studies have targeted plant materials. In the present study, Crocus pallasii subsp. haussknechtii has been evaluated for anti-angiogenesi...

objective(s):recently anti-inflammatory effects of antidepressants have been demonstrated. venlafaxine belongs to newer antidepressants with serotonin norepinephrine reuptake inhibition property. the pain alleviating properties of venlafaxine in different pain models such as neurogenic pain, diabetic neuropathy, and fibromyalgia have been demonstrated. anti-inflammatory effects of venlafaxine a...
