Concept of Communication through Artificial Intelligence technology
PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.
Molecular Model of Infliximab, or Remicade, a monoclonal antibody against tumour necrosis factor alpha (TNF-α), which is used to treat autoimmune diseases
