Introduction:

The 1989 Nobel prize winner in Chemistry, Prof. Thomas R. Cech from the BioFrontiers Institute, USA has published a research paper in the 13 December 2012 Nature (492(7428):285-9; and I.F: >42) stating that “The TEL patch of telomere protein TPP1 mediates telomerase recruitment and processivity.”  This study provides mechanistic insights into how TPP1 regulates telomerase function.

In connection with this finding, Dr Boominathan, Founder Director-cum-chief scientist of GBMD, reports that: Anti-telomerase cancer therapy: Bisindole-PBD (Compound 5b) suppresses the expression of Tripeptidyl Peptidase 1 (TPP1) and inhibits cancer progression via down-regulation of its target gene


Significance:

Given that: (1) over 90% human tumors overexpress immortality gene telomerase; (2) cancer causes the highest economic loss compared to all the known causes of death worldwide, there is an urgent need to find: (i) a way to inhibit telomerase activity in human tumors, to increase the efficacy of anticancer therapy;  (ii) a cheaper alternative to the existing expensive drugs; (iii) a side-effect-free natural product-based drug; (iv) a way to effectively treat cancers that are resistant to anti-cancer drugs; and (v) a way to effectively treat and eradicate metastatic progression of cancer.


Research Findings:

Bisindole-PBD (Compound 5b), by decreasing the expression of its target gene, it may suppress the expression of Tripeptidyl Peptidase 1 (TPP1). Thus, pharmacological formulations encompassing Bisindole-PBD (Compound 5b) or its analogs may be used to treat human cancers that specifically over express immortality gene telomerase.
