Epidermal growth factor receptor (EGFR) mutations are leading oncogenic drivers in non-small cell lung cancer (NSCLC). Many third-generation EGFR tyrosine kinase inhibitors (TKIs) have been developed to target EGFR T790M and activating mutations. Osimertinib (AZD9291) was the first approved drug and...

Analysis of the lncRNA-miRNA-mRNA network reveals a potential regulatory mechanism of EGFR-TKIs resistance in NSCLC
nCounter analysis of patients progressed to TKIs
Chronic myeloid leukemia (CML) epitomizes successful targeted therapy, with 86% of patients in the chronic phase treated with tyrosine kinase inhibitors (TKIs) attaining remission. However, resistance to TKIs occurs during treatment, and patients with resistance to TKIs progress to the acute phase c...

In this study, to investigate the underlying molecular mechanisms of how EGFR-TKIs resistance occurs in NSCLC, we examined gene expression using microarray technology on gefitinib-resistant NSCLC cells to obtain differentially expressed (DE) lncRNAs and mRNAs. Then we carried out KEGG enrichment ana...

A431 wild-type (wt) cancer cell line is sensitive to treatment with EGFR tyrosine kinase inhibitors (TKIs). By culturing it chronically under gefitinib, it eventually becomes resistant (A431_GR cell). We know of a few proteins involved in this mechanism of drug resistance, but a cDNA exprssion array...
