Description

The human TIEG1 Elisa kit is suitable for the quantitative measurement of human TIEG1 in serum, plasma, tissue homogenates, or cell lysates. This assay employs the sandwich enzyme immunoassay technique and enzyme-substrate chromogenic reaction. The color develops positively to the amount of human TIEG1 in samples. The color development is stopped and the intensity of the color is measured. This kit displays many advantages, including high sensitivity, strong specificity, good linearity, high precision and recovery, as well as lot-to-lot consistency.

TIEG1, also known as KLF10, is inducibly expressed by TGF-β, bone morphogenetic proteins (BMPs), and other cytokines. It is expressed in specific cell types in numerous tissues and is involved in inhibiting cell proliferation and inflammation as well as inducing apoptosis similar to that of TGFβ. TIEG1 binds to Sp-1-GC-rich DNA sequences and can activate or suppress the transcription of numerous genes. TIEG1 also plays an important role in regulating cell apoptosis and proliferation in various diseases, including pancreatic cancer, leukemia, and osteoporosis.

Target Background

Function
(From Uniprot)
Transcriptional repressor which binds to the consensus sequence 5'-GGTGTG-3'. Plays a role in the regulation of the circadian clock; binds to the GC box sequence in the promoter of the core clock component ARTNL/BMAL1 and represses its transcriptional activity. Regulates the circadian expression of genes involved in lipogenesis, gluconeogenesis, and glycolysis in the liver. Represses the expression of PCK2, a rate-limiting step enzyme of gluconeogenesis. May play a role in the cell cycle regulation.
Gene References into Functions
  1. Results from a study on gene expression variability markers in early-stage human embryos shows that KLF10 is a putative marker for the 3-day, 8-cell embryo stage. PMID: 26288249
  2. Zinc is capable of ameliorating the allogeneic immune reaction by enhancement of antigen-specific iTreg cells due to modulation of essential molecular targets by upregulation of Foxp3 and KLF-10 and downregulation of IRF-1. PMID: 27260002
  3. Thus, our study uncovers a novel regulatory mechanism underlying which KLF10 stability and its biological function are mediated by FBW7. PMID: 29198712
  4. In clinical specimens of lung adenocarcinoma, low KLF10 expression associated with decreased patient survival, consistent with a pivotal role for KLF10 in distinguishing the antiproliferative versus prometastatic functions of TGFbeta. Our results establish that KLF10 functions to suppress TGFb-induced EMT, establishing a molecular basis for the dichotomy of TGFb function during tumor progression. PMID: 28249899
  5. the findings show that TIEG1 is highly expressed in human keloids and that it directly binds and represses Smad7 promoter-mediated activation of TGF-beta/Smad2 signaling PMID: 28108300

  7. TIEG-1 overexpression in normal human skin fibroblasts results in improved resistance to oxidative stress PMID: 26922828

  9. KLF10 directly binds to TGF-BRII promoter in T cells, leading to enhanced gene expression. PMID: 25472963

  21. JARID1B is the first TIEG1 corepressor identified, explaining how TIEG1 represses transcription through inducing histone H3 lysine 4 demethylation, which may be important for TIEG1 function in both normal and cancer cells. PMID: 20863814
  22. KLF10 has been shown to play a major role in the TGFbeta inhibition of cell proliferation and inflammation and induction of apoptosis, and its overexpression in human osteoblasts and pancreatic carcinoma cells mimics the actions of TGFbeta[review] PMID: 20087894
