This week you learned about glycolysis and the chemical reactions and enzymes involved in this important metabolic pathway. You further learned that glyceraldehyde phosphate dehydrogenase (GAPDH) enzyme is not only an important key regulatory enzyme of glycolysis, but also recognized as a “moonshining” enzyme. GAPDH is also long known as an enzyme that is prone to inhibition by many toxins, e.g., Pertussis toxin, alkylating agents and many thiol compounds. You also heard about the Warburg effect in connection with glycolysis.

As you work on this week’s discussion board assignment, consider the following: 

  • Cervical      cancer is the second highest number of deaths in female cancers, exceeded      only by breast cancer. This cancer carries high risks of morbidity and mortality      amongst women.
  • Most      cervical cancers cells show abnormally high glycolysis rates.
  • The      current standard of care for locally advanced cervical cancer is      concurrent cisplatin chemotherapy with pelvic irradiation.
  • Despite      significant advances in radiation treatment delivery, more than 30% of      patients fail this treatment.
