RETRACTED: Crocin Inhibits Angiogenesis and Metastasis in Colon Cancer via TNF-α/NF-kB/VEGF Pathways

Area of Science:

• Oncology
• Molecular Biology
• Pharmacology

Background:

• Angiogenesis and metastasis are critical for cancer progression.
• Crocin, a carotenoid from saffron, has shown potential in inhibiting colon cancer cell growth.
• The precise effects of crocin on angiogenesis and metastasis in colorectal cancer require further investigation.

Purpose of the Study:

• To investigate the role of crocin in inhibiting angiogenesis and metastasis in colorectal cancer.
• To elucidate the molecular mechanisms underlying crocin's anti-cancer effects.

Main Methods:

• In vitro studies using colon cancer cell lines (HT-29, Caco-2) and human umbilical vein endothelial cells (HUVEC).
• Assessing cell viability, migration, invasion, and tube formation.
• Analyzing the impact of crocin on TNF-α, NF-κB, and VEGF signaling pathways.
• In vivo studies using angiogenesis models to evaluate tumor growth inhibition.

Main Results:

• Crocin reduced the viability of colon cancer cells and HUVECs but not normal colon epithelial cells.
• Crocin inhibited cancer cell migration, invasion, and angiogenesis in a concentration-dependent manner.
• Crocin suppressed TNF-α, NF-κB activation, and VEGF secretion, both in vitro and in vivo, reducing tumor growth.

Conclusions:

• Crocin effectively inhibits angiogenesis and metastasis in colorectal cancer.
• The anti-cancer effects of crocin are mediated through the inhibition of the TNF-α/NF-κB/VEGF signaling pathway.
• Crocin represents a potential therapeutic agent for colorectal cancer treatment.
