Abstract: A method for treating cancer stem cells with cold atmospheric plasma using a cold atmospheric plasma system The method comprises the steps of placing an exit port of a cold plasma delivery device 5 cm or less from target cancer stem cells, flowing the inert gas from the source through the housing at a flow rate of 5-10 ml/minute, applying electrosurgical energy of 2-5 kV at a frequency of 20-35 kHz to at least one of the central electrode and the ring electrode to produce a cold plasma jet from the exit port, directing the cold plasma jet onto the target cancer stem cells, and applying the cold plasma jet onto the target cancer stem cells for at least 2 minutes. In a preferred embodiment the inert gas is helium.

Abstract: A device uses cold plasma to treat cancerous tumors. The device has a gas supply tube with a delivery end. The gas supply tube is configured to carry a gas to the delivery end. A syringe is provided having an opening. The syringe is connected to the supply tube and configured to carry the gas to the opening. A first electrode is positioned inside said syringe, and a second electrode is positioned adjacent to the opening. The first and second electrodes excite the gas to enter a cold plasma state prior to being discharged from the opening of the syringe. An endoscopic tube can be used instead of the syringe. An exhaust tube can be provided to remove gas introduced into the body cavity by the cold plasma jet.

Abstract: We have discovered p40, the shortest variant of a new human p53 homologue (p40/p51/p63/p73H). We have also found that it plays a role in cancer. Low level amplification of the p40 locus accompanied by RNA and protein overexpression was observed in primary lung cancers, and head and neck cancer cell lines. P40 protein overexpression in primary lung tumors was limited to squamous cell carcinoma, tumors known to harbor a high frequency of p53 mutations. Overexpression of p40 in Rat 1a cells led to an increase in soft agar growth and tumor size in mice. We searched for p40 binding proteins using the yeast two-hybrid system. P53 was the most common binding target of the 1.6×106 clones screened from a mouse embryonic library. Moreover, coexpression of p40 and p53 led to a decrease in p53 transcriptional activity. Our results support the notion that p40 plays an oncogenic role in human cancer.
