“In the human neuroblastoma SK-N-MC cell line, exogenous PROG (9300–93,000 pg/ml) had a significant effect on overall Tau and nuclear TDP-43 levels, reducing total Tau levels by ∼1.5-fold and increasing nuclear TDP-43 by 1.7- to 2.0-fold.”

“Furthermore, progesterone administration resulted in an increase in the phosphorylation of two epitopes of Tau (Tau‐1 and PHF‐1) phosphorylated by GSK3β, but did not affect the phosphorylation of an epitope of Tau (Ser262) that is GSK3β insensitive.”
“In contrast, progesterone and its metabolites resulted in a significant decrease in the expression of Tau and GSK3β in the cerebellum.”
“The regulation of Tau expression and phosphorylation by progesterone may contribute to the hormonal regulation of cerebellar function by the modification of neuronal cytoskeleton.”
