  • Patent number: 10004775
    Abstract: An extract of Carica papaya leaves obtained from a plant of age six months and younger from the date of germination of the seed is used as an inhibitor of HIF to effectively block hypoxia-inducible factor (HIF) function and methods of use thereof. More specifically it relates to the use of the Carica papaya plant extract to eliminate unwanted cells by inhibiting HIF in the prevention and treatment of hypoxia-related conditions and diseases such as inflammatory diseases, vascular diseases, cancer and infectious diseases. In a particular embodiment, a solid hypoxic tumor in a patient is treated by administering to the patient a therapeutically acceptable amount of an extract of Carica papaya leaves obtained from a plant of age six months and younger from the date of germination of the seed, preferably an alcohol extract such as a methanol extract, whereby to inhibit hypoxia-inducible factors in the tumor.

  • Patent number: 9995730
    Abstract: The present invention relates to the construction of a new hypoxia inducible factor (HIF) responsive reporter gene construct, the genetic constructs and vectors containing the same. Further, the present invention relates to a stable cell line comprising the HIF responsive reporter construct, as well as methods and uses of the inventive constructs and cell lines to identify modulators of HIF activity.

  • Publication number: 20050186661
    Abstract: A biologically pure strain of Bacillus stearothermophilus F1 capable of Producing protease which is tolerant to any organic compound selected from the group leucine, cysteine, arginine, glycine, asparagine (BDH) and aspartic acid. Peptone iv derived from soybean was the best organic compound for the enzyme production. Sodium nitrate, ammonium salts and amino acids as sole nitrogen sources interfered with protease formation. In addition Bacteriocin-release-protein (BRP) system was used for the release of heterologous proteins from Escherichia coli into culture medium. The gene from the alkaline protease was cloned from Bacillus stearothermophilus F1 and the recombinant F1 protease was efficiently excreted into the culture medium using two vectors pTrcHis bearing the protease gene and pJL3 containing the BRPs. The recombinant enzyme was purified through single-step heat treatment at 70° C. for 3 hours at pH level from 8 to 10.
