All-Trans Retinoic Acid Reduces Matrix Metalloproteinase-2 and Increases E-Cadherin Levels in BeWo Choriocarcinoma Cells

All-trans-retinoic acid: measurement

A quantitative determination of physiological levels of all-trans-retinoic acid (vitamin A acid) in human serum has been developed. A double-phase extraction of 3.5 ml of serum followed by a specific and sensitive high performance liquid chromatography procedure allowed measurement of levels down to 1 ng/ml. Serum concentrations in 37 fasting volunteers ranged from 2.7 to 4.2 ng/ml and fitted a...

All-trans Retinoic Acid Regulates the Balance of Treg-Th17 Cells through ERK and P38 Signaling Pathway

Studies on Multifunctional Effect of All-Trans Retinoic Acid (ATRA) on Matrix Metalloproteinase-2 (MMP-2) and Its Regulatory Molecules in Human Breast Cancer Cells (MCF-7)

Background. Vitamin A derivative all-trans retinoic acid (ATRA) is considered as a potent chemotherapeutic drug for its capability of regulating cell growth and differentiation. We studied the effect of ATRA on MMP-2 in MCF-7, human breast cancer cells, and the probable signaling pathways which are affected by ATRA on regulating pro-MMP-2 activity and expression. Methods. Gelatin zymography, RT...

All-Trans Retinoic Acid Increases Aquaporin 3 Expression in Human Vaginal Epithelial Cells

INTRODUCTION Water channel aquaporin 3 (AQP3) is an aquaglyceroporin that transports small neutral solutes and water. All-trans retinoic acid (ATRA), a member of the retinoid drug class, acts as a regulator in several biological processes. AIM To investigate the effect of ATRA on the expression of AQP3 in human vaginal epithelial cells. METHODS Human vaginal mucosal epithelial cells (CRL261...

All-trans-retinoic acid and bleeding/thrombosis.

Hematology-Oncology Department Ospedali Riuniti Largo Barozzi, 1 24128 Bergamo (Italy) Tel. 39 035 269492, Fax 39 035 266659 E-Mail [email protected] All-trans-retinoic acid (ATRA) inhibits cell growth and proliferation by inducing cyto-differentiation and/or apoptosis in several cell types. These effects have become a therapeutic objective in human cancers. In addition to these functions, ...
