ABSTRACT

Objective:

Isoorientin (ISO) is a flavonoid compound extracted from plant species. The goal of this study was to determine the potential antiproliferative effects of ISO in HT-29 human colorectal adenocarcinoma cell line in vitro, specifically on cell viability, apoptosis, and cell cycle pathways. Materials and

Methods:

The cytotoxic effect of ISO isolated from E. spectabilis was measured using 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assay in HT-29 cell lines. Total RNA was isolated using Tri-Reagent protocol. The effects of ISO on apoptosis-related gene were detected using real-time polymerase chain reaction (RT-PCR). The findings were analyzed using "Delta-Delta CT" ΔΔCT method and evaluated using a computer program. Volcano plot analysis was used for comparing groups and the data obtained were statistically analyzed using Student t test.

Results:

According to XTT result analysis, the 50% inhibitory concentration (IC50) value of ISO was 125 µM at the 48th h in HT-29 cells. The RT-PCR analysis in HT-29 cells showed that Cyclin D1 (CCND1 ), Cyclin-dependent kinase 6 (CDK6), BAX, BCL-2, Checkpoint kinase 1-2 (CHEK1, CHEK2) and Excision repair cross-complementing 1 (ERCC1) expressions were reduced in ISO-treated cells compared with those in the control group of cells. P53, P21, Caspase-3 (CASP-3), Caspase-8 (CASP-8), and Caspase-9 (CASP-9) gene expressions were increased Ataxia Telengiectasia and Rad-3 related (ATR) was activated in the ISO-treated group of cells compared with those in the control group of cells (p<0.05).

Conclusion:

ISO affected the proliferation of colorectal cancer (CRC) cells via cell cycle pathways. It also altered apoptosis gene expression. These results demonstrated that ISO can be a therapeutic agent for CRC treatment; however, more studies are needed to investigate its mechanism of actions.
