Recent research has revealed that an extract of GP, HH-F3, could inhibit the proliferation of liver cancer cells, could lessen liver fibrosis in rats, and could reduce the secretion of Aβ and the phosphorylation of Tau proteins in induced pluripotent stem cell (iPSC)-derived neurons from AD patients [19,20,21,22]. The gene discussed is MAPT; the disease is Alzheimer disease.
