Some factors lead to carcinogenesis like infectious diseases. Parasites like\u00a0Toxoplasma gondii, by its components, could modulate the cancer system by inducing apoptosis. The objective of this investigation is to assess the potential of peptides derived from\u00a0T. gondii\u00a0in combating cancer by examining their effects on Caco-2, Hep-G2, and HT29 cell lines.\nMaterials and methods:\u00a0Candidate peptide by its similarity to anticancer compounds was predicted through the computer-based analysis\/platform. The impact of the peptide on cell viability, cell proliferation, and gene expression was evaluated through the utilization of MTT assay, flow cytometry, and real-time polymerase chain reaction (PCR) methodologies.\nResults:\u00a0The cell viability rate exhibited a significant decrease (p &lt; 0.001) across all cell lines when exposed to a concentration of \u2264160 \u03bcg. Within the 48-hour timeframe, the half maximal inhibitory concentration (IC50) for HT29 and Hep-G2 cell lines was determined to be 107.2 and 140.6 \u03bcg\/mL, respectively. Notably, a marked decrease in the expression levels of\u00a0Bcl2\u00a0and\u00a0APAF1\u00a0genes was observed in both the Hep-G2 and HT29 cell lines.\nConclusion:\u00a0These findings indicate that the\u00a0T. gondii\u00a0peptide affected cancer cell mortality and led to changes in the expression of genes associated with apoptosis.<\/jats:p>","DOI":"10.33393\/dti.2024.3177","type":"journal-article","created":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T14:30:59Z","timestamp":1727706659000},"page":"70-77","source":"Crossref","is-referenced-by-count":4,"title":["Enhancement of apoptosis in Caco-2, Hep-G2, and HT29 cancer cell lines following exposure to Toxoplasma gondii peptides"],"prefix":"10.33393","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6941-6360","authenticated-orcid":false,"given":"Firooz","family":"Shahrivar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3312-765X","authenticated-orcid":false,"given":"Javid","family":"Sadraei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0046-4772","authenticated-orcid":false,"given":"Majid","family":"Pirestani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1202-6147","authenticated-orcid":false,"given":"Ehsan","family":"Ahmadpour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"18642","published-online":{"date-parts":[[2024,9,30]]},"reference":[{"key":"13331","doi-asserted-by":"crossref","unstructured":"Flegr J, Prandota J, Sovi\u010dkov\u00e1 M, Israili ZH.
