Breast Tumor Angiogenesis and Tumor-Associated Macrophages: Histopathologist's Perspective
Much progress has been made since the conceptualization of tumor angiogenesis-the induction of growth of new blood vessels by tumor-as a salient feature of clinically significant primary or metastatic cancers. From a practicing histopathologist's point of view, we appraise the application of this concept in breast cancer with particular reference to the evaluation of proangiogenic factors and t...
متن کاملCCL18 from tumor-associated macrophages promotes angiogenesis in breast cancer.
The infiltration of tumor-associated macrophages (TAMs) is associated with extensive angiogenesis, which contributes to a poor prognosis in breast cancer. However, anti-angiogenic therapy with VEGF-specific monotherapy has been unsuccessful in treating breast cancer, and the molecular mechanisms associated with chemoresistance remain unclear. Here, we investigated whether CCL18, a chemokine pro...
متن کاملRole of tumor associated macrophages in tumor angiogenesis and lymphangiogenesis
Tumor angiogenesis is an essential process for supplying rapidly growing malignant tissues with essential nutrients and oxygen. An angiogenic switch allows tumor cells to survive and grow, and provides them access to vasculature resulting in metastatic disease. Monocyte-derived macrophages recruited and reprogrammed by tumor cells serve as a major source of angiogenic factors boosting the angio...
متن کاملFlowcytometric Analysis of Tumor Associated Macrophages in Invasive Ductal Carcinoma of Breast
Background: Invasive ductal carcinoma is the most common type of breast cancer in Iran. Impaired immune responses occur frequently in cancer patients, but the mechanisms of the induced immune defects remain poorly understood. It is believed that infiltrated immune cells, especially macrophages, may provide help for tumor cell growth and metastasis. Objective: To analyze the status of tumor as...
متن کاملP157: Periostin Recruits Tumor Associated Macrophages in Glioblastoma Multiform
Glioblastoma multiform (GBM) is the most common and lethal type of primary brain tumors with high rates of morbidity and mortality. Treatment options are limited and ineffective in most of the cases. Epidemiological studies have shown a link between inflammation and glioma genesis. In addition, at the molecular level, pro-inflammatory cytokines released from activated microglia can increa...
