General description

TP53-induced glycolysis and apoptosis regulator (TIGAR) is a p53 target gene mapped to human chromosome 12p13-3. The gene contains six exons and it is characterized with two possible p53 binding sites, one upstream of the first exon (BS1) and one within the first intron (BS2).
Monoclonal Anti-TIGAR (mouse IgG2b isotype) is derived from the hybridoma 9C10 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a peptide corresponding to a fragment in exon 6-encoding region of human TIGAR . TIGAR expression was found to correlate with fludarabine sensitivity in chronic lymphocytic leukemia (CLL) cells.

Application

Monoclonal Anti-TIGAR antibody produced in mouse has been used in:
  • enzyme linked immuno sorbent assay (ELISA)
  • immunoblotting
  • immunoprecipitation

Biochem/physiol Actions

TP53-induced glycolysis and apoptosis regulator (TIGAR) inhibits glycolysis by decreasing the fructose-2, 6-bisphosphate levels in cells. This p53 induced protein also plays a vital role in regulation of intracellular reactive oxygen species (ROS) levels. TIGAR expression is associated with oncogenesis and development of several human cancers. Overexpression of TIGAR is observed in colorectal cancer patients. Thus, TIGAR expression might function as a potential biomarker for diagnosis of colorectal cancer and it can act as a target for developing therapeutics for the treatment of colorectal cancer. Nullified expression of TIGAR, increases the radiosensitivity of tumor cells and also enhances the autophagy activity in cells with nutrient starvation or metabolic stress. TIGAR increases cancer cell survival rate in response to tumor chemotherapy by inhibiting both apoptosis and autophagy.

The p53 tumor-suppressor protein prevents cancer development through various mechanisms, including the induction of cell-cycle arrest, apoptosis, and the maintenance of genome stability. We have identified a p53-inducible gene named TIGAR (TP53-induced glycolysis and apoptosis regulator). TIGAR expression lowered fructose-2,6-bisphosphate...
