Background/Aim:
Signal transducer and activator of transcription 3 (STAT3), Janus Kinase 1 (JAK1), extracellular signal-regulated kinase (ERK), and protein kinase B (AKT) are essential for malignant transformation and progression in colorectal cancer (CRC) and can be considered as targets for therapeutic interventions. Hyperforin, an active constituent from Hypericum perforatum, has been reported to inhibit inflammation. However, whether hyperforin may suppress CRC progression via inactivation of JAK/STAT3, ERK or AKT signaling remains unclear.
Materials And Methods:
Human CRC cells were used to identify the treatment efficacy of hyperforin and its underlying mechanisms of action by MTT, flow cytometry, wound healing, and western blotting assays.
Results:
Hyperforin not only induced cytotoxicity, extrinsic/intrinsic apoptosis signaling, but also suppressed the invasion/migration ability of CRC. The phosphorylation of STAT3, JAK1, ERK and AKT was found to be decreased by hyperforin.
Conclusion:
Hyperforin inactivates multiple oncogenic kinases and induces apoptosis signaling in CRC cells.
Insights
Hyperforin, derived from Hypericum perforatum, effectively suppresses colorectal cancer (CRC) progression by inhibiting key signaling pathways like JAK/STAT3, ERK, and AKT, while also inducing cancer cell death.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- Signal transducer and activator of transcription 3 (STAT3), Janus Kinase 1 (JAK1), extracellular signal-regulated kinase (ERK), and protein kinase B (AKT) are crucial for colorectal cancer (CRC) development.
- Hyperforin, a compound from Hypericum perforatum, is known for anti-inflammatory properties, but its effect on CRC signaling pathways was unexplored.
Purpose of the Study:
- To investigate the efficacy of hyperforin in suppressing colorectal cancer (CRC) progression.
- To elucidate the molecular mechanisms by which hyperforin affects CRC, specifically targeting JAK/STAT3, ERK, and AKT signaling pathways.
Main Methods:
- Human colorectal cancer (CRC) cells were utilized to assess hyperforin's effects.
- Standard assays including MTT, flow cytometry, wound healing, and western blotting were employed to determine treatment efficacy and mechanisms.
Main Results:
- Hyperforin demonstrated significant cytotoxicity against CRC cells.
- The compound inhibited CRC cell invasion and migration.
- Hyperforin reduced the phosphorylation of key signaling proteins: STAT3, JAK1, ERK, and AKT.
Conclusions:
- Hyperforin effectively inactivates multiple oncogenic kinase pathways implicated in CRC.
- The study concludes that hyperforin induces apoptosis signaling in colorectal cancer cells, suggesting its therapeutic potential.
