  • Patent number: 11878997
    Abstract: This invention relates to methods of administering compounds containing selenium, selenocysteine, or a selenocysteine peptide to treat, for example, conditions associated with selenium deficiency, or ferroptoptic, parthanototic, and endoplasmic reticulum stress, and/or cancer. The methods of treatment may activate or inhibit (via TFAP2C and Sp1 proteins) the adaptive homeostatic response of the selenome. The compounds may contain a targeting sequence that causes them to be delivered to specific organs and/or tissues. The compounds may be administered, for example, orally, intranasally, intravenously, or by a minimally invasive catheter or BrainPath.
