Mendelian randomization combined with transcriptomic data reveals LINC00652 as a protective factor against the risk of acute lymphoblastic leukemia

LINC00652 plays pivotal roles in acute lymphoblastic leukemia (ALL) a heterogeneous hematological malignancy. Here, we investigated the potential regulatory mechanisms of LINC00652 in ALL. Genome-wide association study data for LINC00652 were obtained for Mendelian randomization and integrated with RNA sequencing data, Bioinformatics analyses, including weighted gene co-expression network analysis (WGCNA), Spearman or Pearson correlation analysis, function, immune microenvironment, subcellular localization, and competing endogenous RNA (ceRNA) network construction, were employed explore the potential mechanisms of LINC00652 in ALL. LINC00652 exhibited no significant causal relationship with ALL but was identified as a protective factor (<i>p</i> &gt; 0.05). LINC00652 levels were significantly decreased in patients with ALL, while WGCNA demonstrated the significance of black and blue modules for ALL. Seventy-nine messenger RNA (mRNAs) (SYT7) significantly correlated with LINC00652 (<i>p</i> &gt; 0.05) and were enriched in the Janus kinase/signal transducer and activator of transcription (STAT), interleukin 2-STAT5, apoptosis, and adipogenesis pathways. Twenty-eight immune cells infiltrated the ALL, with immature B-cells and gamma delta T-cells significantly associated with LINC00652 expression (<i>p</i> &lt; 0.05). LINC00652 was predominantly cytoplasmic, and a ceRNA network involving LINC00652, 36 microRNAs, and 18 mRNAs were proposed. LINC00652 May protect against ALL and influence its pathogenesis through ceRNA mechanisms.
