REG1A and lung carcinoma: Moreover, based on gene set enrichment analysis (GSEA) with The Cancer Genome Atlas (TCGA) dataset, we found that TRIM65 was positive related to cell cycle, metastasis up and RHOA-REG pathways, which was further validated by RT-PCR and Western blot in TRIM65 knockdown lung cancer cells and indicated a possible mechanism underlying its effects on lung cancer.
