1. Field of the Invention
The present invention relates generally to a novel microorganism strain, Salmonella typhimurium CRC2631, and it use as a cancer therapeutic.
FIG. 1: Fluorescent CRC2636 binds preferentially to PC-3M cells but not to normal RWPE-1 cells.
FIG. 2: CRC2631 more effectively invades PC-3M carcinoma cells over time.
FIG. 3: Archived S. typhimurium preferentially targets PC-3M prostate carcinoma cells but do not target normal RWPE-1 prostate cells.
“Agent” or “Therapeutic Agent:” As used herein, the terms “agent” and “therapeutic agent” refer to any natural or synthesized composition that when administered to a subject relieves the subject of disease or improves health. Wherein the disease being treated is cancer. The “agent” or “therapeutic agent” may be a pro-drug, further defined below.
“Bind, Binds, or Interacts With:” As used herein, “bind,” “binds,” or “interacts with” means that one molecule recognizes and adheres to a particular second molecule in a sample, in vitro or in vivo, but does not substantially recognize or adhere to other structurally-unrelated molecules in the sample. Generally, a first molecule that “specifically binds” a second molecule has a binding affinity of greater than about 105 or 106 moles/liter for that second molecule.
“Gene:” As used herein, the term “gene” means a nucleic acid molecule that codes for a particular protein, or in certain cases, a functional or structural RNA molecule.
