AKT1 Phosphorylates FDX1 to Promote Cuproptosis Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study demonstrates that copper activates the AKT signaling pathway, which inhibits ferredoxin‐1 (FDX1), a key regulator of cuproptosis. AKT1‐mediated FDX1 phosphorylation not only abrogates FDX1‐induced cuproptosis and aerobic respiration but also promotes glycolysis.

PCSK9 Promotes the Malignancy of Triple‐negative Breast Cancer Cells by Reducing Cholesterol Levels at the Plasma Membrane to Activate EGFR and HER3

Advanced Science, EarlyView.
By decreasing cholesterol and lipid raft levels in the plasma membrane, proprotein convertase subtilisin/kexin type 9 (PCSK9) boosts human epidermal growth factor receptor 1 and 3 (EGFR and HER3) activation, driving tumor growth and metastasis in triple‐negative breast cancer (TNBC).

FGF2 Mediated USP42‐PPARγ Axis Activation Ameliorates Liver Oxidative Damage and Promotes Regeneration

Advanced Science, EarlyView.
USP42 is identified as a novel DUB of PPARγ in hepatocytes. USP42 mediated PPARγ deubiquitylation determines its transcriptional preference on proliferative and redox balance genes. USP42 knockdown exacerbates liver damage and delays regeneration. FGF2 is the upstream signal that initiates and activates the USP42‐PPARγ axis.
