Abstract Background To investigate the anticancer effects of 5-Fluorouracil (5-FU), thymoquinone (TQ), and/or coenzyme Q10 (CQ10), alone and combined, in HT29, SW480, SW620 human colorectal cancer (CRC) cell lines. Methods Cell cycle progression apoptosis were assessed by flow cytometry. Gene protein expression molecules involved (BLC2, survivin, BAX, Cytochrome-C, Caspase-3), (CCND1, CCND3, p21, p27), PI3K/AKT/mTOR/HIF1α oncogenic pathway, glycolysis (LDHA, PDH, PDHK1) also analysed quantitative RT-PCR Western blot. Oxidative stress markers (ROS/RNS, MDA, Protein carbonyl groups) antioxidants (GSH CAT) quantified ELISA. Results All treatments resulted depicted arrest apoptosis, with TQ demonstrating greater efficacy than CQ10, both without 5-FU. However, 5-FU/TQ/CQ10 triple therapy exhibited most potent pro-apoptotic activity all lines, portrayed lowest levels oncogenes BCL2, survivin) highest upregulation tumour suppressors (p21, p27, Caspase-3). The showed strongest suppression a concurrent increase its endogenous inhibitors (PTEN AMPKα) lines used. Additionally, favoured glucose oxidation upregulating while decreasing LDHA PDHK1 enzymes. displayed significant decline antioxidant increases oxidative markers. Conclusions This study is first to demonstrate superior compared 5-FU, CRC treatment. Moreover, this report reveal improved therapy, potentially through promoting phosphorylation, attenuating increasing stress-induced apoptosis.
