Evaluation of cytotoxic and anti-tumor activity of partially purified serine protease isolate from the Indian earthworm Pheretima posthuma

Exact molecular mechanism of the cytotoxic and antitumor activities is yet to be explored and currently we are working on ultra-purification and biophysical characterization of this fraction. Further investigation into the mechanism(s) of cytotoxic and antitumor activities at molecular level would be useful in treatment of various classes of cancer and viral infections in future.
