Target gene or protein PCSK9
Gene or Protein evidence PS treatment significantly reduced PCSK9 expression and normalized LDLR levels in collected primary and recurrent breast tumors at the study end.
Target pathways NA
IC50 At 24h, 48h, 72h: 260.83 μM, 98.88 μM, 93.64 μM against BT-474 respectively 260.83 μM, 120.92 μM, 113.08 μM against T47D respectively
Potency PS is a novel first-in-class PCSK9-targeting lead appropriate for the use to control hormone-dependent BC progression and recurrence.
Cell line/ mice model BT-474, T47D
Additional information  The results of this study provide the first evidence for the suppression of the hormone-dependent breast tumor progression and recurrence by targeting the PCSK9-LDLR axis.
