Cancer invasion of the surrounding tissue is a multiscale process collective cell movement that involves not only tumour cells but also other immune in environment, such as tumour-associated macrophages (TAMs). The heterogeneity these cells, with two extremes being pro-inflammatory and anti-tumour M1 anti-inflammatory pro-tumour M2 has significant impact on cancer interact different ways ExtraC...

Inflammatory cells play important roles in progression of solid neoplasms including ovarian cancers. Tumor-associated macrophages (TAMs) contribute to angiogenesis and immune suppression by modulating microenvironment. Ovarian cancer develops occasionally on the bases of endometriosis, a chronic inflammatory disease. We have recently demonstrated differential expressions of CXCR3 variants in en...

BACKGROUND The ability of malignant tumors to metastasize presents a severe challenge in cancer treatment. Lymphatic vessels provide one of the main routes for tumor-metastasis on the way to regional lymph nodes. Increasing evidence suggests that inflammatory cells play an important role in tumor-associated angiogenesis and lymphangiogenesis. Recent data show that a specialized sub fraction of ...

BACKGROUND Treatment failure during highly active antiretroviral therapy (HAART) is ultimately common and associated with the development of resistance mutations. Trizivir (zidovudine/lamivudine/abacavir) and tenofovir disoproxil fumarate may improve adherence and enhance virological suppression in individuals who have failed previous regimens. METHODS Individuals were identified who had fail...

This study analyses the effects of vagotomy on tumor growth and survival in a murine, pancreatic cancer model in wild-type and TNFα-knockout (-/-) mice.Throughout many operative procedures in the upper gastrointestinal tract the partial or complete transection of the vagus nerve or its local nerve fibers is unavoidable. Thereby its anti-inflammatory effects in residual tumor tissue may get lost...

Purpose: The presence of tumor-associatedmacrophages (TAM) in breast cancer correlates strongly with poor outcome. The purpose of this study was to develop a clinically applicable, noninvasive diagnostic assay for selective targeting and visualization of TAMs in breast cancer, based on magnetic resonanceI and clinically applicable iron oxide nanoparticles. Experimental Design: F4/80-negativemam...

We show by immunohistochemical labeling that prominent cell types in the tumor microenvironment of PyMT transgenic mice are tumor-associated macrophages (TAMs) and endothelial cells, and that both populations are decreased in the presence of mitochondrial targeted catalase (mCAT). This observation suggests that mitochondrial ROS can drive tumor invasiveness in conjunction with the presence of T...

It is unclear how tumor-associated macrophages (TAMs) contribute to the initiation of oncogenesis and how they are regulated at the molecular level. By using a lineage-specific deletion strategy, we found that heat shock protein 90kDa β (Grp94), member 1 (HSP90B1), a master chaperone for Toll-like receptors and integrins also known as GP96, critically endows TAMs with the ability to promote gen...

Tumor-associated macrophages (TAMs) play a central role in tumor progression, metastasis, and recurrence after treatment. Macrophage plasticity and diversity allow their classification along a M1-M2 polarization axis. Tumor-associated macrophages usually display a M2-like phenotype, associated with pro-tumoral features whereas M1 macrophages exert antitumor functions. Targeting the reprogrammin...

Tumor-associated macrophages (TAMs) are key components of the tumor microenvironment in non-medullary thyroid cancer (TC), the most common endocrine malignancy. However, little is known regarding the regulation of their function in TC. Transcriptome analysis in a model of TC-induced macrophages identified increased inflammatory characteristics and rewiring of cell metabolism as key functional c...
