Methylation-specific PCR confirmed PTX4 promoter methylation in multiple AML cell lines including THP-1, and treatment with the demethylating agent 5-azacytidine restored PTX4 expression. To elucidate the molecular mechanisms by which PTX4 exerts its tumor suppressive function, we performed RNA-sequencing analysis of THP-1 cells with stable PTX4 overexpression compared to empty vector controls. Total RNA was extracted from three biological replicates each of THP-1-EV and THP-1-PTX4-OE cells using the RNeasy mini kit (Qiagen). RNA library construction and sequencing were performed by Novogene Singapore using the Illumina NovaSeq 6000 platform with paired-end sequencing. Raw reads were quality-assessed using FastQC v0.11.5, followed by adapter trimming and alignment to the human reference genome (GRCh38/hg38). Pathway analysis demonstrated that PTX4 suppresses oncogenic programs including NF-κB signaling, IL-17 signaling, and Toll-like receptor pathways, while enhancing T cell receptor signaling and MAPK pathways. This dataset provides molecular insights into PTX4-mediated tumor suppression in AML and supports its potential as a therapeutic target through demethylating agents.</description><dates><publication>2026/06/01</publication></dates><accession>GSE316513</accession><cross_references><GSM>GSM9455117</GSM><GSM>GSM9455116</GSM><GSM>GSM9455115</GSM><GSM>GSM9455119</GSM><GSM>GSM9455118</GSM><GSM>GSM9455120</GSM><GPL>24676</GPL><GSE>316513</GSE><taxon>Homo sapiens</taxon></cross_references></HashMap>
