Ferroptosis Sensitization in Pancreatic Cancer
Research goal
What are the key molecular regulators of ferroptosis in pancreatic cancer cells, and how might their modulation enhance chemotherapy sensitivity?
Example overview
The proposals share a redox-resistance theme. Priority should go to biomarker-stratified combinations with orthogonal death-pathway controls before moving beyond cell and organoid models. The ranked program deliberately keeps competing mechanisms separate, then uses perturbation, rescue, and independent-model replication to decide which should advance.
Leading hypotheses
CPEB1-low tumors depend on NRF2 redox buffering
CPEB1-low pancreatic cancer models may have a measurable NRF2-buffering state that predicts reduced response to a ferroptosis-inducing combination.
ARID3A-PTEN-GPX4 status selects a chemosensitization subgroup
An ARID3A-high, PTEN-suppressed subgroup may be selectively sensitized when ferroptosis resistance is relieved during gemcitabine exposure.
Early lipid-peroxidation kinetics predict durable combination response
Early lipid-peroxidation kinetics may distinguish transient stress from a durable ferroptosis-linked chemosensitization response.
