The effects of insulin on the expression levels of ADAMTS6 & 19 in OUMS-27 cell
Journal Title: Dicle Tıp Dergisi - Year 2014, Vol 41, Issue 3
Abstract
Objective:A Disintegrin-like Metalloproteinase with Thrombospondin Motifs (ADAMTS) proteins are kind of matrix metalloproteinase enzymes that primarily founds in the extracellular matrix (ECM). Insulin is an important anabolic hormone, which acts on many tissues. The aim of this study is to evaluate the time-dependent effects of insulin on the two functionally unknown enzyme expressions (ADAMTS6 & 19) in OUMS-27 human chondrosarcoma cell line. Methods: OUMS-27 cells were cultured in Dulbecco’s modified Eagle’ medium (DMEM) alone and DMEM containing 10 μg/mL insulin. The medium was changed every other day up to 11th day. Cells were harvested at 1, 3, 7, and 11th days and RNA isolation was performed at appropriate times according to study setup. The levels of RNA expression of ADAMTS6 and 19 were estimated by qRT-PCR using appropriate primers. Results: According to qRT-PCR analysis, ADAMTS6 mRNA expression was found to be decreased as early as one day after insulin application and continued up to day 11, the last day of insulin induction (p=0.008). The ratio of ADAMTS6 in insulin-applied groups was changed between 1/2 and 1/4 of control values. The changes in ADAMTS19 mRNA levels in insulin-applied cells were not statistically significant compared to control cell group. Conclusion: Our results demonstrated that insulin has a potential effect on lleviation of loss of extracellular matrix compounds by diminishing ADAMTS6 levels. To test this hypothesis and finding, more investigations are needed to recognize the real functions of orphan ADAMTS proteins. Key words: Insulin, ADAMTS6, ADAMTS19, chondrosarcoma, OUMS-27, RNA
