The Anti-tumoral Effect of β-D-Mannuronic Acid (M2000) as a Novel NSAID on Treg Cells Frequency and MMP-2, MMP-9, CCL22 and TGFβ1 Gene Expression in Pre-surgical Breast Cancer Patients.

The Anti-tumoral Effect of β-D-Mannuronic Acid (M2000) as a Novel NSAID on Treg Cells Frequency and MMP-2, MMP-9, CCL22 and TGFβ1 Gene Expression in Pre-surgical Breast Cancer Patients. Iran J Allergy Asthma Immunol. 2019 Feb;18(1):80-90 Authors: Kashefi S, Ahmadi H, Omranipour R, Mahmoodzadeh H, Jafarnezhad-Ansariha F, Tofighi Zavareh F, Mirshafiey A Abstract With respect to the role of chronic inflammation in the induction and progression of breast cancer (BC). The relationship between tumor and tumor microenvironment may be a hopeful strategy for BC therapy. According to the effect of β-D-Mannuronic acid (M2000) as a novel non-steroidal anti-inflammatory drug (NSAID) on BC murine model and 4T1 cell line, we started to study that was a phase II, randomized, controlled clinical trial. 24 women with BC were included in this study and were followed by fixed oral doses of M2000, 500 mg two times a day (6-8 weeks). Blood samples were collected at baseline and weeks 6-8. To compare the patterns of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), C-C motif chemokine ligand 22 (CCL22) and The transforming growth factor-beta 1 (TGFβ1) gene expression and T regulatory cells (Tregs) frequency of healthy women normal controls with BC patients, a set of 10 blood samples of  women healthy volunteers was collected. The gene expression was evaluated by quantitative Real-time PCR (qRT-PCR) and the frequency of Tregs was ...
