Tissue inhibitor of metalloproteinase-1 (TIMP-1) regulates mesenchymal stem cells through let-7f microRNA and Wnt/β-catenin signaling.

Tissue inhibitor of metalloproteinases 1 (TIMP-1) is a matrix metalloproteinase (MMP)-independent regulator of growth and apoptosis in various cell types. The receptors and signaling pathways that are involved in the growth factor activities of TIMP-1, however, remain controversial. RNA interference of TIMP-1 has revealed that endogenous TIMP-1 suppresses the proliferation, metabolic activity, ...

angiotensin ii differentially induces matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 production and disturbs mmp/timp balance

angiotensin ii, the main component of the renin-angiotensin system, is associated with cardiovascular diseases such as hypertension, vascular remodeling and inflammation. remodeling process results from dysregulation of matrix metalloproteinases (mmps) and their tissue inhibitors (timps). mmps are considered as important target genes for angiotensin ii. the aim of this study was to determine th...

All trans-retinoic acid selectively down-regulates matrix metalloproteinase-9 (MMP-9) and up-regulates tissue inhibitor of metalloproteinase-1 (TIMP-1) in human bronchoalveolar lavage cells.

BACKGROUND The balance between proteinases and antiproteinases plays an important role in tissue destruction and remodelling. In chronic obstructive pulmonary disease (COPD) and emphysema, an imbalance between matrix metalloproteinases (MMPs) and inhibitors of tissue metalloproteinase (TIMPs) has been reported. Alveolar macrophages are considered to be the main source of MMPs. We therefore have...

Astrocytic tissue inhibitor of metalloproteinase-1 (TIMP-1) promotes oligodendrocyte differentiation and enhances CNS myelination.

Tissue inhibitor of metalloproteinase-1 (TIMP-1) is an extracellular protein and endogenous regulator of matrix metalloproteinases (MMPs) secreted by astrocytes in response to CNS myelin injury. We have previously reported that adult TIMP-1 knock-out (KO) mice exhibit poor myelin repair following demyelinating injury. This observation led us to hypothesize a role for TIMP-1 in oligodendrogenesi...

the let-7f microrna functions as a negative regulator of hnf4a expression in human adipose tissue-derived stem cells

objective: micrornas (mirnas) are noncoding rnas that function as key regulators of diverse biological activities such as cellular metabolism, cell proliferation and cell cycle regulation. recent studies have indicated the high potential of these small molecules to control stem cell differentiation into desired cells. the aim of present study is to investigate the possible effect of let-7f on e...
