  9. 9.  Scutellariabaicalensis  <br />Anti-proliferative and apoptotic activity against acute lymphocytic leukemia, lymphoma and myeloma cell lines<br />inhibits cellular growth<br />Chinese skullcap<br />
  10. 10. Targeting tumors with peptides from natural sources<br />Sujit K. Bhutia and Tapas K. Mai, IIT<br />Natural products that contained necrotic peptides, apoptotic peptides, function-blocking peptides, anti-angiogenic peptides, and immunostimulatory peptides in the context of their ability to induce tumor regression <br />Indian scenario – usage of natural products for cancer cure<br />
  11. 11. Indian Americans pioneering cancer research from herbal extracts<br />January 11, 2011 <br />Orally administering 12 grams per day for three months, curcumin was found to inhibit proliferation of cells.<br />no side-effects in the animals<br />

The Hollings Cancer Institute at the University of South Carolina has conducted a study on a group of 500 cervical cancer patients <br />Ellagic acid is causing so-called G-arrest within 48 hours (inhibiting and stopping mitosis-cancer cell division) and apoptosis  in several cancer types<br />This is found in different foods.<br />Ellagic Acid<br />
  14. 14. Green Tea: A recent study from Japan demonstrates that green tea goes way beyond it's role as a well-known antioxidant.<br /> One of the factors that sets cancer cells apart from normal cells is that they have telomerase, an enzyme that maintains telomeres on the ends of DNA. Most normal cells do not have telomerase to maintain their telomeres. Every time a normal cell divides, telomeres are lost.<br />ECGC – telomerase inhibitor<br />Destroy cancer cells<br />Several other natural products are explored for effective cancer treatment in future!<br />FUTURE<br />
