Abstract:
:Colorectal cancer occurs throughout the world but is most common in developed countries. Cancer progression is believed to be driven by genetic mutations in this complex condition. Risk factors for developing colorectal cancer include a genetic family history, long-term ulcerative colitis, and colonic polyps. The use of baicalin has been reported to be clinically efficacious against colon tumors in Asian countries despite an unclear mechanism of action. Several cancers have been found to be biologically dependent on the specificity protein 1 (sp1) transcription factor family. We hypothesized that baicalin may exert its chemotherapeutic effects by sp1 downregulation. Using the SW480 human colorectal cancer cell line, we investigated the physiological properties of baicalin. Our experiments were designed toward clarifying three goals: (a) to determine the mRNA expression profile of transcription factors in colorectal cancer patients using a microarray-based analysis; (b) to determine the effects of baicalin on the sp1 transcription factor with western blotting and reporter cell assays; and (c) to contrast the effects of mithramycin-A (an sp1 transcription factor inhibitor) and baicalin using western blotting and reporter cell assays. Both baicalin and mithramycin-A downregulated sp1 expression, attenuated SW480 cell proliferation, and increased cell apoptosis. Baicalin inhibited sp1 expression and led to SW480 apoptosis, thus clarifying the effect of this traditional Chinese medicine compound in the treatment of colon cancer.
