Targeting the tumor microenvironment (TME) pathways with ACROBio

Data obtained from The Global Cancer Observatory (GCO) reports that cancer is currently one of the most serious diseases throughout the world. There are nearly 20 million new cancer cases and almost 9.6 million deaths.

Besides an extensive range of genetic and epigenetic alterations, components of the tumor microenvironment tend to exert a significant impact on tumor progression.

The so-called tumor microenvironment (TME) is known to be the environment around the tumor and includes the encircling blood vessels, fibroblasts, signaling molecules, immune cells and the extracellular matrix (ECM).

Such cellular and non-cellular components of TME have the ability to reprogram the processes of tumor emergence and development by controlling various cascade signaling pathways.

Therefore, gaining better insights into the basic cellular and molecular mechanisms controlling these interactions could be an innovative strategy to interrupt cancer development and add up to the development of effective and safe therapeutic strategies to combat cancer.

At present, the TME has turned out to be a hot area for antibody drug development and cancer treatment. ACROBiosystems has come up with a range of TME-related targets, like TGF-β, Notch, etc., supporting cancer treatment and accelerating the R&D procedure of users.

 

Hot targets

TGF-β

  • Foster angiogenesis and migration in TME
  • Cytokines exhibiting pleiotropic biological activities
  • Suppress immune system by controlling the function of immune cell groups in the TME

Notch

  • Control the cell differentiation, proliferation, apoptosis and cell boundary formation
  • High expression in malignant tumors
  • Communication with FGF and Wnt signaling pathways, maintain cancer stem cell (CSC) growth and reshape the TME
