At the Kenneth R. Peak Brain & Pituitary Tumor Treatment Center, we are developing new and exciting treatments to fight cancer through our genomic sequencing and proteomics labs, novel approaches such as mitochondrial smart bombs, nanosyringes that allow us to inject agents into individual cancer cells, drug pump inhibitors that keep those agents in the cells (meaning lower doses of chemotherapy are necessary) and new and unique gene therapies.
Some of the investigational therapies we are developing include nanosyringes (especially their role in delivering highly targeted cellular drug pump blockers), mitochondrial-based “smart bomb” chemotherapy and gene therapy for treatment of glioblastomas, the most common and most aggressive malignant primary brain tumor in humans.
DR. DAVID BASKIN EXPLAINS HOW A CANCEROUS GLIOMA IS TRICKED INTO TAKING IN A DAMAGING DRUG
Mitochondrial “Smart Bombs”
Monoamine oxidase B (MAO-B) is a mitochondrial enzyme that is restricted to brain cells and is highly expressed in glioma. We have developed a mitochondrial “smart bomb,” a drug that is transformed by MAO-B into a form that is selectively imported into the mitochondria of the cancer cell where it attacks the mitochondrial DNA, disrupting power generation in the cell and making the cell generate harmful free radicals. This leads to the death of the cancer cell.
DAVID BASKIN, MD EXPLAINS HOW NANOSYRINGES CAN TARGET DRUG DELIVERY TO A SINGLE CANCER CELL
Nanosyringes for Drug Delivery
Our scientists at the center, in collaboration with Nobel Laureate Richard E. Smalley, PhD and James Tour, PhD of Rice University, have developed a form of nanosyringe to treat malignant tumors. The nanosyringes are microscopic carbon barrels made by shattering carbon nanotubes and then attaching a substance such as polyethylene glycol to make them soluble in the blood. We load the nanodevice with chemotherapy drugs then we target the cancer cell by attaching an antibody that sticks to the proteins that are expressed on the surface of the cancer cell; the antibody keeps the chemotherapy drug in place. Once the syringe binds to the cancer cell and the antibody dissipates, the chemotherapy drug is released in the immediate vicinity of the cancer cell. This selective microinjection therapy has potential for reducing chemotherapy side effects because it delivers smaller dosages and primarily the cancer cell receives most of the drug.
DR. DAVID BASKIN EXPLAINS HOW INSERTING A MODIFIED COLD VIRUS IN THE BRAIN CAN KILL GLIOBLASTOMA
Using a Trojan Horse to Kill Glioblastoma Cancer in the Brain
This gene therapy approaches uses a common cold virus as shuttle to deliver conditionally active herpes virus DNA directly into brain cancer cells. After delivery of 10 injections of the altered cold virus into the margins of a tumor, the virus spreads rapidly through the tumor. Gene expression is then activated with valacyclovir (Valtrex), commonly used to treat cold sores, and the modified cold virus interrupts the cancer’s cell replication cycle thereby killing the cell. This therapy was shown to be safe and nontoxic in a Phase Ib study and a Phase 2a study is in progress.
