Druggable genome-wide Mendelian randomization integrating GWAS and eQTL/pQTL data identifies targets for lung squamous cell carcinoma.

ABSTRACT: Lung squamous cell carcinoma (LUSC) is one of the most common types of non-small cell lung cancer with poor prognosis. Druggable genome-wide Mendelian randomization (MR) was conducted to discover LUSC-related targets using expression quantitative trait loci (eQTL) and protein QTL (pQTL) in the ieu_b_4953 dataset and finngen dataset. Bayesian co-localization analysis, summary‑data‑based MR (SMR) analysis, and HEIDI test were conducted to verify the causal associations between genes and LUSC risk. Prediction of prognosis and immune infiltration was performed at the transcriptomic level, and expression patterns of genes were analyzed at the single-cell level. We identified DNMT1, ACSS2, YBX1, SELENOS, PPARA, MST1, CPA4, and MPO as LUSC-related genes based on MR analysis. Although Bayesian co-
