Thalidomide inhibits inflammation and angiogenesis in tumor 4T1 growth in mice

چکیده
Results Daily oral dose of thalidomide was able to reduce in 46% the tumor volume. Assessment of tumor vascularization revealed a significant decrease in blood vessels formation by thalidomide. The levels of two cytokines, VEGF and TNF-a were decreased in tumor samples of thalidomidetreated group compared with the control group. Accumulation of neutrophils or macrophages in the 4T1 tumor measured by the activities of inflammatory enzymes, MPO for neutrophils and NAG for macrophages, was inhibited by the treatment. Conclusions By targeting key components of 4T1 tumor simultaneously, thalidomide was effective in attenuating tumor growth. This approach, suppression of inflammation and angiogenesis may provide further insights for both prevention and treatment of cancer.

Objective(s): Controversial results have been reported regarding the anti-tumor properties of extracellular vesicles derived from mesenchymal stem cells (MSCs). The present study was conducted to evaluate whether secretome derived from Human Wharton’s jelly mesenchymal stem cells (hWJMSCs) may stimulate or inhibit breast cancer growth in vitro and in vivo.<st...
متن کاملLicochalcone E present in licorice suppresses lung metastasis in the 4T1 mammary orthotopic cancer model.
We investigated whether licochalcone E (LicE), a phenolic constituent of licorice, inhibits mammary tumor growth and metastasis using animal and cell culture models. 4T1 mammary carcinoma cells were injected into the mammary fat pads of syngeneic BALB/c mice. Starting 7 days after the injection, the mice received LicE (7 or 14 mg/kg body weight/day) via oral gavage for 25 days. LicE suppressed ...
متن کاملCombined therapy of local and metastatic 4T1 breast tumor in mice using SU6668, an inhibitor of angiogenic receptor tyrosine kinases, and the immunostimulator B7.2-IgG fusion protein.
The therapeutic efficacy of combined antiangiogenic and immune therapy was tested against weakly immunogenic and highly metastatic 4T1 breast tumor using SU6668, an angiogenesis inhibitor and recombinant murine (rm) B7.2-IgG fusion protein, an immunostimulator. SU6668 inhibits the tyrosine kinase activity of three angiogenic receptors VEGFR2 (Flk-1/KDR), PDGFRbeta, and FGFR1, which play a cruci...

Background: Tumor associated antigens can be viably used to enhance host immune response. Objectives: The immunomodulatory effect of biogenic selenium nanoparticles (SeNPs) was compared between treated and untreated mice with crude antigens of 4T1 cells. Materials and Methods: Female inbred BALB/c mice (60) were injected by cancinogenic 4T1 cells causing breast cancer. After 10 days, all tumor ...
متن کاملThe Effect of Interval Training on the Expression of Tumor Suppressor Gene, Systemic Inflammation, and Tumor Volume in Breast Cancer–Bearing BALB/c Mice
Introduction: E-cadherin is expressed in most normal epithelial tissues. Loss of E-cadherin can cause dedifferentiation and invasiveness in human carcinomas, leading E-cadherin to be classified as a tumor suppressor. Therefore, the aim of this study was to investigate the effect of interval training on the expression of tumor suppressor gene E-cadherin in breast cancer-bearing BALB/c mice. Meth...
