Advanced cancers: eradication in all cases using 3-bromopyruvate therapy to deplete ATP.
نویسندگان
چکیده
A common feature of many advanced cancers is their enhanced capacity to metabolize glucose to lactic acid. In a challenging study designed to assess whether such cancers can be debilitated, we seeded hepatocellular carcinoma cells expressing the highly glycolytic phenotype into two different locations of young rats. Advanced cancers (2-3cm) developed and were treated with the alkylating agent 3-bromopyruvate, a lactate/pyruvate analog shown here to selectively deplete ATP and induce cell death. In all 19 treated animals advanced cancers were eradicated without apparent toxicity or recurrence. These findings attest to the feasibility of completely destroying advanced, highly glycolytic cancers.

Hexokinase-2 bound to mitochondria: cancer's stygian link to the "Warburg Effect" and a pivotal target for effective therapy.
The most common metabolic hallmark of malignant tumors, i.e., the "Warburg effect" is their propensity to metabolize glucose to lactic acid at a high rate even in the presence of oxygen. The pivotal player in this frequent cancer phenotype is mitochondrial-bound hexokinase [Bustamante E, Pedersen PL. High aerobic glycolysis of rat hepatoma cells in culture: role of mitochondrial hexokinase. Pro...
متن کاملThe Reversal Effects of 3-Bromopyruvate on Multidrug Resistance In Vitro and In Vivo Derived from Human Breast MCF-7/ADR Cells
PURPOSE P-glycoprotein mediated efflux is one of the main mechanisms for multidrug resistance in cancers, and 3-Bromopyruvate acts as a promising multidrug resistance reversal compound in our study. To test the ability of 3-Bromopyruvate to overcome P-glycoprotein-mediated multidrug resistance and to explore its mechanisms of multidrug resistance reversal in MCF-7/ADR cells, we evaluate the in ...
متن کاملNovel therapy for liver cancer: direct intraarterial injection of a potent inhibitor of ATP production.
Most types of cancer are difficult to eradicate and some, like liver carcinomas, are almost always fatal. Significantly, we report here that direct intraarterial delivery of 3-bromopyruvate (3-BrPA), a potent inhibitorof cell ATP production, to liver-implanted rabbit tumors, inflicts a rapid, lethal blow to most cancer cells therein. Moreover, systemic delivery of 3-BrPA suppresses "metastatic"...

Background and Aims: Chemotherapy is utilized as a part of combined-modality programs to achieve organ preservation and improve survival in patients with locally advanced head and neck cancer. Combinedmodality protocols can be used in three forms: a) neoadjuvant induction chemotherapy before definitive surgery or radiotherapy; b) concomitant chemoradiotherapy; and c) sequential therapy consisti...

Background and Purpose: Each year, about 50,000 new cases of cancer occur in Iran and the most common being the gastrointestinal (GI) tract (38%). Colorectal cancers account for the 3rd and 4th most prevalent cancers in Iranian men and women, respectively. Since genetic and environmental factors lead to differences in colorectal cancer occurrence in different geographic regions and races, we ...
