Disease relevance of Timp1

 

High impact information on Timp1

  • The 28- and 38-kD proteins were shown to be identical to the tissue inhibitor of metalloproteinase-1 (TIMP-1) and the proenzyme form of cathepsin L, respectively [5].
  • Ribonuclease protection analysis of liver RNA extracted at each recovery time point demonstrated a rapid decrease in expression of the collagenase inhibitors TIMP-1 and TIMP-2, whereas collagenase mRNA expression remained at levels comparable to peak fibrosis [6].
  • Local overexpression of TIMP-1 prevents aortic aneurysm degeneration and rupture in a rat model [7].
  • TIMP-1 overexpression did not effect cell proliferation [8].
  • Overexpression of TIMP-1, -2, or -3, or a synthetic MMP inhibitor similarly inhibited SMC chemotaxis and invasion through reconstituted basement membrane [8].
 

Chemical compound and disease context of Timp1

 

Biological context of Timp1

 

Anatomical context of Timp1

  • Western blotting was used to identify a specific MMP, MMP2 (a gelatinase that digests basement membrane collagen and the dominant MMP observed on zymography) and a specific TIMP, TIMP2 [14].
  • RESULTS: MMP and TIMP coding transcripts were detectable in all liver cell types by reverse transcription-polymerase chain reaction; however, the cellular expression levels were markedly different as assessed by Northern blot analysis [17].
  • In the newly forming CL at 24 h after hCG administration, the luteal cells expressed TIMP-1, -2, and -3 mRNA, although the pattern of cellular expression was unique for each of the TIMPs [18].
  • Immunoreactive TIMP-1 was increased in experimental rats and primarily localized in alveolar macrophages [15].
  • The mRNAs for MMP-9, TIMP-1, and -3 were mainly expressed in epithelial cells on day 1-5 [19].
 

Associations of Timp1 with chemical compounds

  • TIMP-1 and TIMP-2 were constitutively expressed, and only TIMP-1 displayed a moderate increase with hyperoxia [20].
  • Terazosin evoked a significant increase in the activity of proMMP-2 and MMP-2 but did not affect TIMP [21].
  • All diabetes-associated changes in renal function and MMP/TIMP were attenuated after benazepril treatment with reduced IV-C accumulation [22].
  • All diabetes-associated changes in MMP and TIMP mRNA and activities were attenuated by perindopril treatment in association with reduced type IV collagen accumulation [23].
  • Pirfenidone partially inhibits the enhancement of the expression of TGF-beta 1 and TIMP-1 in lung tissue [24].
 

Physical interactions of Timp1

 

Regulatory relationships of Timp1

  • Our data suggest that FSH stimulation of TIMP-2 expression may be regulated independently to that of TIMP-1 [26].
  • CMT-3 posttreatment increased TIMP-1 level and thereby inhibited MMP-9, which in turn decreased TGF-beta1 and caspase-3 signaling pathways and improved survivability in septic rats [27].
  • TGF beta1 enhanced the expression of tissue inhibitors of metalloproteinases (TIMP) 1 and 3 and caused a modest decrease of TIMP 2 mRNA levels [28].
  • We conclude that emodin effectively inhibits PMA- and TGFbeta1-stimulated TIMP-1 expression in hepatic stellate cells by suppressing the AP-1 signaling pathway and extracellular signal-regulated kinase activation, respectively [29].
  • We recently demonstrated that IGFs inhibit bone collagen degradation, and we postulated that they may either inhibit the expression of interstitial collagenase or stimulate the synthesis of tissue inhibitors of metalloproteinase-1 (TIMP-1), -2, or -3 [30].
 

Other interactions of Timp1

  • Westerns were run on the MMPs known to cleave fibrillar collagen in the rat (MMP-8, -13, and -14) as well as TIMP-1, -2, and -4 [2].
  • In contrast, TIMP-1 and TIMP-3 expression in E19 scarring wounds increased six-fold and four-fold, respectively [31].
  • IL-10 exhibits an antifibrogenic effect by suppressing MMP-2 and TIMP-1 expression [32].
  • MMP-13 active form was elevated during the first 2 weeks post-MI while TIMP-1 and TIMP-2 protein levels were not significantly elevated until 2 weeks post-MI [2].
  • Partial hepatectomy was followed by a dramatic increase of MMP-14 and to a lesser extent also of TIMP-1 expression; other MMPs and TIMPs were not significantly induced [33].
 

Analytical, diagnostic and therapeutic context of Timp1

  • RT-PCR demonstrated the presence of mRNA for metalloproteinase inhibitors TIMP1 and TIMP2 in PSCs while reverse zymography revealed the presence of functional TIMP2 in PSC secretions [14].
  • The present study was designed to assess whether expression of mRNA for extracellular matrix (ECM) components, metalloproteinases (MMP) and tissue inhibitor of metalloproteinases (TIMP) in glomeruli is affected by a low protein diet during the course of focal glomerulosclerosis (FGS) [34].
  • Total collagen IV, the different alpha(IV) chains, matrix degrading metalloproteinases (MMP), and tissue inhibitors of metalloproteinases (TIMP) were quantified by immunocytochemistry and/or Western blotting [35].
  • Correct polymerase chain reaction product amplification was confirmed by probing the blotted polymerase chain reaction product with a 32P-labeled oligonucleotide specific for a given MMP or TIMP [36].
  • There was a marked elevation of TIMP-1 mRNA expression after UUO, which was first noted at 12 h after ureteral ligation [37].
