GSE119004: Establishment and disease modeling of non-small cell lung cancer organoids

Bulk RNA sequencing

Purpose: The goal of this study is to establish and molecularly characterize non-small cell lung cancer (NSCLC) organoids. Generation of NSCLC organoids would provide additional preclinical models for drug screening and biomarker discovery.; Methods: Patient lung tumors and previously established patient-derived xenografts (PDX) were processed to generate organoids. Total RNA was extracted and subjected to RNA-seq to examine the gene expression similarity between patient/PDX/organoid of the same model using t-SNE clustering.; Results: Through RNA-sequencing, we generated TPM values of patient, PDX and organoid samples of 5 models. t-SNE analysis showed that the patient/PDX/organoid of the same models clustered together. The lung adenocarcinoma samples formed a separate cluster from the squamous cell carcinoma samples based on gene expression.; Conclusions: Our study introduces the establishment of NSCLC organoids and demonstrates the gene expession similarity of the organoid model to its corresponding PDX and patient sample.
