Background: There are few clinical challenges associated with the treatment of colorectal cancer (CRC). Studies have shown that TGF-β plays a crucial role in CRC. Importantly, celastrol, a major components of the root extract of the traditional Chinese herb, has been shown to inhibit the growth, adhesion, and metastasis of human CRC cells through the inhibition of TGF-β1/Smad signaling.

Materials and methods: Real-time PCR and Western blot tests were proceeded to present TGF-β1, TGF-β receptor type I (TGFβRI), TGF-β receptor type II (TGFβRII), Smad2/3, p-Smad2/3, Smad4, and glyceraldehyde-3-phosphate dehydrogenase expression in human colon cancer cell samples.

Results: Our results indicated that celastrol can reduce the expression levels of TGF-β1, TGFβRI, and TGFβRII in HCT116 and SW620 cells. Furthermore, celastrol could also prevent the increase in Smad4 and p-Smad2/3 in HCT116 and SW620 cells.

Conclusion: Celastrol could inhibit tumor growth through TGF-β1/Smad signaling and might be a promising therapeutic component against CRC.
