While conventional treatments are effective initially, the disease can become resistant or relapse over time. This study aimed to examine the differentially expressed genes at the transcriptome level and molecular pathways in DLBCL patients.  \nMethods: This investigation utilized RNA sequencing analysis to compare differentially expressed gene samples from five diffuse large B-cell lymphoma patients with two healthy volunteers. These participants were admitted to UKM Medical Center, Kuala Lumpur between 2019 and 2020. The differentially expressed genes were identified using the DESeq2 R package (version 1.10.1) using a negative binomial distribution model. The obtained P values were corrected with the Benjamin and Hochberg method and identified using a False Discovery Rate threshold of \u003C0.05, with log2 fold change (FC) of ≥2 or ≤-2 . Results:Resultsshowed73differentiallyexpressedgenesbetween the two groups, among which 70 genes were downregulated, and three genes were upregulated. The differentially expressed genes analyzed with the Reactome pathway were significantly associated with the downregulation of antimicrobial humoral response (P\u003C0.001), neutrophil degranulation (P\u003C0.001), chemokine receptors bind chemokines (P=0.028), defensins (P=0.028) and metabolism of angiotensinogen (P=0.040). Conclusion: These findings suggest that the identified pathways may contribute to cancer progression and weaken the immune response in diffuse large B-cell lymphoma patients. This study offers fresh insights into previously undiscovered downstream targets and pathways modulated by diffuse large B-cell lymphoma.  \nPlease cite this article as: Johdi NA, Seng A, Lee WK, Mohamad Said HZ, Wan Jamaluddin WF.
