Disease relevance of TIMP-1

 

High impact information on TIMP-1

 

Biological context of TIMP-1

  • The 887-basepair cDNA obtained was 95%, 86%, and 77% identical to the reported nucleotide sequences of bovine, human, and mouse TIMP-1 cDNAs, respectively [3].
  • Concentrations of TIMP-1 mRNA in luteal tissue did not differ throughout the luteal phase (P = 0.07) [3].
  • We previously reported a decrease in luteal TIMP-1 within 15 min of prostaglandin F(2 alpha) (PGF(2 alpha))-induced luteolysis [4].
  • Expression of mRNA for TIMP-1 and TIMP-2 was examined by Northern analysis of endometrial RNA derived from steroid-treated ovariectomized ewes and from intact ewes during the estrous cycle and early pregnancy [5].
  • In experiment 1, we tested the effects of PGF(2alpha) administration (Day 10 postestrus; Day 0 = estrus) on luteal TIMP-1, -2, and -3 mRNA and protein expression [6].
 

Anatomical context of TIMP-1

  • However, TIMP-1 mRNA was localized predominantly to specific cells located in the connective tissue surrounding and within day 3 corpora lutea [3].
  • We investigated whether PGF(2alpha) also influenced the endogenous protein levels of tissue inhibitors of metalloproteinases, TIMP-1 and TIMP-2, and matrix metalloproteinases, MMP-2 and MMP-9, all of which have been implicated in remodeling of the extracellular matrix (ECM) [7].
  • TIMP-1 immunoreactivity was observed within the granulosa cells of postsurge but not presurge follicles [8].
  • TIMP-1 was secreted by both epithelial and stromal cells in primary culture, and its identity was confirmed by Western analysis, while reverse zymography demonstrated TIMP-1 and TIMP-2 along with a putative ovine TIMP-3 in the culture medium from both cell types [5].
  • TIMP-1 immunoactivity was localized in large luteal cells, smooth muscle and endothelial cells, and in all antral follicles, including oocytes [9].
 

Associations of TIMP-1 with chemical compounds

  • Serum concentrations of progesterone and luteal concentrations of TIMP-1 mRNA and protein were similar at 0 and 6 h after PGF(2alpha) injection on Day 3 postestrus [6].
  • In situ hybridization for MCP-1 mRNA combined with immunocytochemical labeling of tissue inhibitor of metalloproteinase-1 (TIMP-1) in large luteal cells was used to determine whether the steroidogenic cells that have PGF2alpha receptors express MCP-1 mRNA in response to PGF2alpha [10].
 

Other interactions of TIMP-1

  • In parallel to the development of LVH at B, gene expression was increased significantly for MMP-1, MMP-2, MMP-3, and MMP-9 and for TIMP-1 and TIMP-2 and decreased significantly for TIMP-3 [11].
  • In contrast to the rapid decrease in TIMP-1 and -2 levels, an increase in MMP-2 activity (165% of controls, P < 0.05) occurred at 8 h, which corresponded to the nadir in plasma progesterone [7].
  • Collagen I, III and IV, alpha-smooth muscle actin, MMP-1, 2 and 9, TIMP-1 and 2 and PAX2 protein were assessed using immunochemistry [12].
  • It has been suggested in postnatal animal studies that dysregulation of the RAS, and subsequent increased expression of TGF-beta1 and TIMP1, leads to changes in extracellular matrix composition [1].
