    Background: In recent years, natural products have received great attention for cancer prevention owing to their various health benefits, noticeable lack of toxicity and side effects, and the limitations of chemotherapeutic agents. Andrographolide, a labdane diterpenoid is a principal bioactive constituent of Andrograp his paniculata Nees, exhibits significant anticancer activity.

    Background Hedgehog signaling pathway (Hh) is abnormally stimulated in colon cancer. Evidence suggests the therapeutic effectiveness of andrographolide against several cancers. This study attempts to delineate the effect of andrographolide on Hh signaling pathway in colon cancer HCT-116 cells.Methods:Effects of andrographolide were studied on HCT-116 cells by evaluating cytotoxicity by MTT assay, morphology assessment, trypan blue exclusion, and colony formation assay; migratory potential by scratch assay; apoptosis by DAPI, Hoechst staining, FITC-Annexin V assay, and caspases activation; mitochondrial membrane potential (Delta psi m) by Mito Tracker and Rhodamine 123. Intracellular ROS by DCFH-DA staining. Cell cycle regulation by flow cytometry. Expression of BAX, BAD, BCL2, Cyclin B1, CDK1, Smo, and Gli1 by qRT-PCR. Interaction between andrographolide and Smo protein by in-silico molecular docking.Results:Andrographolide induced antiproliferative effect on HCT-116 cells in a dose-dependent and time-dependent manner. It also induced apoptosis and anti-migratory effect in HCT-116 cells. In combination with 5FU, andrographolide exhibited synergistic effect. It Induced G2/M phase arrest through downregulating CDK1 and Cyclin B1. Andrographolide also inhibited Hh signaling by downregulating Smo and Gli1 in HCT-116 cells. It showed high affinity toward Smo protein in-silico.Conclusion:Andrographolide repressed the colon cancer cell growth via inhibiting Hh signaling pathway.
