Several fundamental studies over 20 years by Mirko Beljanski PhD aimed to study what the plant extract Pao pereira could bring to the treatment of brain tumors, especially glioblastoma (GMB). This is the most common and aggressive type of cancer, affecting neuron-support cells called astrocytes. The 1-year and 2-year relative survival rates for GBM are 29.6% and 9.0%, respectively. Only 3.4% of patients with a GBM diagnosis survive more than 5 years.(1,2)
The Beljanski Foundation is collaborating with researchers at the University of California at San Francisco to study the effectiveness of a plant extract, Pao pereira against glioblastoma. This extract was originally developed by French scientist Mirko Beljanski at the Pasteur Institute in Paris. He showed that the Pao pereira extract has a broad spectrum of anti-cancer activity.(3)
Preclinical cell-based studies at UCSF are positive and it has been decided to move forward with an animal model. Exciting results are expected by fall.
For any agent to be successful against brain cancer it must cross the blood-brain barrier—a natural filter that prevents potentially harmful molecules from entering the brain. Beljanski showed that the active compounds in his Pao pereira extract do cross the blood brain barrier and so may exert their anti-tumor effect on brain cancers, including glioblastoma. This observation is critical to the success of the animal studies at UCSF.
Our work is made possible by the generous donations of individuals who believe in the mission of The Beljanski Foundation and share our commitment to making the discoveries of Professor Beljanski available to as many people as possible.
