Butrin Tackles Retinoblastoma – A Clinical Hypothesis †
Abstract: Breach of association of legumain protein activities to the corresponding cellular components results in over-expression of legumain, and constitutes a key biomarker for a variety of life-taxing sicknesses like cancer, Alzheimer’s/Parkinson’s and acute kidney injury. To suppress the functions of legumain, it is hypothesized that a water soluble and edible biomolecule, namely, butrin (7, 3’, 4’-trihydroxy flavanone-7, 3’-diglucoside) may have the therapeutic potential owing to its special ability to bind …
