Defactinib inhibits FAK/SRC-JNK signaling, suppressing ferroptosis by modulating ACSL4 expression. This pathway impacts cancer therapy and acute pancreatitis, offering new therapeutic targets.
Area of Science:
- Cell Biology
- Molecular Biology
- Pathology
Background:
- Ferroptosis, an iron-dependent cell death, is implicated in diseases.
- Modulating ferroptosis presents therapeutic opportunities.
Purpose of the Study:
- To identify novel regulators of ferroptosis.
- To investigate the role of FAK/SRC-JNK signaling in ferroptosis.
- To explore therapeutic potential in cancer and pancreatitis.
Main Methods:
- Defactinib identified as a ferroptosis suppressor.
- Analysis of FAK/SRC-JNK signaling pathway.
- Investigated transcription factor regulation of ACSL4.
- Utilized cancer cell models and acute pancreatitis models.
Main Results:
- FAK/SRC-JNK signaling upregulates ACSL4, promoting ferroptosis.
- Specific transcription factors (ATF2, NFATC1/3, SMAD4) promote ferroptosis via ACSL4.
- Other transcription factors (c-Jun, STAT3, ELK1, HSF1) inhibit ferroptosis via ACSL4.
- Elevated FAK/SRC-JNK sensitizes cancer cells to ferroptosis therapies.
- Inhibition of FAK/SRC-JNK protects against acute pancreatitis.
Conclusions:
- FAK/SRC-JNK signaling is a key regulator of ferroptosis.
- Targeting FAK/SRC-JNK pathway offers therapeutic strategies for cancer and acute pancreatitis.
