In news- Recently, researchers at the Indian Institute of Technology (IIT), Kanpur, have discovered a particular gene (DLX1).

About DLX1 protein–

  • The DLX1 plays an important role in the development of jaws, skeleton, and interneurons in the brain.
  • It has an important role to play in the growth and development of prostate cancer.
  • The DLX1 protein is found at elevated levels in prostate cancer patients, the reason why the DLX1 protein has been used as a urine-based biomarker. 
  • Homeobox protein DLX-1 is a protein that in humans is encoded by the DLX1 gene.
  • Now the team of researchers fromIIT Kanpur has found that the DLX1 protein, which is expressed at higher levels in the prostate cancer cells, has a huge role in the growth and development of the tumour and the spread of the cancer to other organs in the body (metastasis).
  • Using small molecules as inhibitors, the researchers have shown in mice a new therapeutic strategy to treat people with DLX1-positive prostate cancer.

Key findings related to prostate cancer & DLX1 protein- 

  • Androgen receptor is responsible for promoting the development of prostate cancer. 
  • Also, about 50% of prostate cancer harbors an aberrant gene which is a product of two genes (TMPRSS2 and ERG) being fused together and results in production of higher levels of ERG protein.
  • About 96% of TMPRSS2-ERG fusion-positive prostate cancer patients show high levels of DLX1 protein as well. 
  • In concert with this, about 70% of the patients with high androgen receptor signaling also have elevated DLX1 protein levels.
  • The researchers have further shown that both androgen receptor and fusion gene product, ERG, are responsible for increased levels of DLX1 in prostate cancer cells.
