Demonstrate the function of dysregulated miR-365a-5p-PELI3 signaling axis in the generation of gefitinib resistance during treatment for non-small-cell lung cancer (NSCLC). All the NSCLC patients who participated in this research were recruited from the Second Hospital of Hebei Medical University. PC9 cells and PC9GR cells were cultured for experiments. Patients who were primary resistant to EGFR-tyrosine kinase inhibitor had lower miR-365a-5p levels. MiR-365a-5p directly targeted PELI3 mRNA. MiR-365a-5p overexpression enhanced the function of gefitinib in inhibiting cell viability. Tumor growth was suppressed through miR-365a-5p in nude mice. Dysregulated miR-365a-5p-PELI3 signaling axis triggered the generation of gefitinib resistance in NSCLC.

Preclinical studies have shown that the anti-malarial drug hydroxychloroquine (HCQ) improves the anti-cancer effects of various therapeutic agents by impairing autophagy. These findings are difficult to translate in vivo as reaching an effective HCQ concentration at the tumor site for extended times is challenging. Previously, we found that free HCQ in combination with gefitinib (Iressa, ZD1839) significantly reduced tumor volume in immunocompromised mice bearing gefitinib-resistant JIMT-1 breast cancer xenografts.

Background: The incidence and mortality of lung cancer are high, and treatment with epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) is the preferred first-line treatment for patients suffering from non-small cell lung cancer (NSCLC) with EGFR mutations. However, EGFR-TKI resistance leads to treatment failure. Yifei-Sanjie pill (YFSJ) is a novel type of Chinese patent medicine for lung cancer.

Esophageal cancer is a grave malignant condition. While radiotherapy, often in conjunction with chemotherapy, serves as a cornerstone in the management of locally advanced or metastatic cases, patient tolerance and treatment resistance frequently hinder its efficacy. Cell-in-cell structures, prevalent in various tumors, have been linked to prognosis.

Mesenchymal-epithelial transition factor (MET) gene mutation is a large class of mutations commonly seen in non-small cell lung cancer (NSCLC). MET mutation includes subtypes such as MET exon 14 skipping mutation (METex14m) and MET amplification (METamp). For advanced NSCLC with METex14m, Savolitinib has a high sensitivity as a member of tyrosine kinase inhibitors (TKIs).
