Expressions of RNAs were analyzed with Affymetrix Genechip <em>C. elegans </em>Genome Array and Genespring GX11 software where differentially expressed genes were further analyzed using gene ontology (GO). Selected genes (unc-15, cit-1.2, ftn-1, rsks-1, unc-4 and daf-12) were analyzed with RT-qPCR to validate the results.</p> <p><strong><em>Results: </em></strong>TRF modulated the expression of 314 genes involved in determination of adult lifespan, regulation of growth and lipid modification. A total of 440 genes involved in RNA metabolic processes, transcription, growth and differentiation of muscle and nerve cells were differently expressed following H202 induction. TRF treatment before and after H202- induction resulted in 438 differentially expressed genes involved in RNA metabolic processes, transcription, response to xenobiotic stimulus and protein amino acid phosphorylation.</p> <p><strong><em>Conclusion</em></strong>: TRF modulates the expression of genes involved in the regulation of lifespan in <em>C. elegans</em>.</p> <p>Bangladesh Journal of Medical Science Vol.18(4) 2019 p.711-721</p>}, number={4}, journal={Bangladesh Journal of Medical Science}, author={Aan, Goon Jo and Karim, Noralisa Abdul and Zainudin, Mohd Shahril Aszrin and Makpol, Suzana}, year={2019}, month={Aug.}, pages={711–721} }
