  • Patent number: 10421801
    Abstract: Cytotoxic factors having use in modulating cell death, and their use in methods of treating necrosis or apoptosis-related conditions are disclosed. The invention also relates to methods for identifying active agents useful in treating conditions related to cell death or uncontrolled growth. The present inventors have found that different microorganisms produce different cytotoxic factor(s) having anticancer activity. The substantially pure cytotoxic factors can be used in a method of treating an infectious disease or a cancer.

  • Patent number: 10072049
    Abstract: The present invention discloses methods and materials for delivering a cargo compound into a brain cancer cell and/or across the blood-brain barrier. Delivery of the cargo compound is accomplished by the use of protein transport peptides derived from Neisseria outer membrane proteins, such as Laz. The invention also provides synthetic transit peptides comprised of the pentapeptide AAEAP. The invention further discloses methods for treating cancer, and specifically brain cancer, as well as other brain-related conditions. Further, the invention provides methods of imaging and diagnosing cancer, particular brain cancer.

  • Patent number: 9107881
    Abstract: The present invention relates to compositions comprising cupredoxins, and their use to inhibit angiogenesis in mammalian cells, tissues, and animals, and particularly the angiogenesis that accompanies tumor development and particularly in humans. Specifically, the present invention relates to compositions comprising the cupredoxin(s), and or peptides that are variants, derivatives or structural equivalents of cupredoxins, which retain the ability to inhibit angiogenesis in mammalian cells, tissues or animals. These compositions may be peptides or pharmaceutical compositions, among others. The compositions of the invention may be used to treat any pathological condition that has as a symptom or cause, inappropriate angiogenesis, and particularly inappropriate angiogenesis related to tumor development.
