Non-small cell lung cancer (NSCLC), EGFR downstream pathway activation and TKI targeted therapies sensitivity: Effect of the plasma membrane-associat…
2017
Adenocarcinoma of Non-Small Cell Lung Cancer (NSCLC) is a severe disease. Patients carrying EGFR mutations may benefit from EGFR targeted therapies (e.g.: gefitinib). Recently, it has been shown that sialidase NEU3 directly interacts and regulates EGFR. In this work, we investigate the effect of sialidase NEU3 overexpression on EGFR pathways activation and EGFR targeted therapies sensitivity, in a series of lung cancer cell lines. NEU3 overexpression, forced after transfection, does not affect NSCLC cell viability. We demonstrate that NEU3 overexpression stimulates the ERK pathway but this activation is completely abolished by gefitinib treatment. The Akt pathway is also hyper-activated upo…

Editorial: Emerging heterocycles as bioactive compounds
2023
Heterocycles represent a privileged scaffold due to their ability to interact with biological systems via heteroatoms. It is no coincidence that every year the Food and Drug Administration approves numerous new drugs that contain at least one heterocyclic system as active pharmacophoric part in their structure. Many heterocyclic compounds with therapeutic properties, including anticancer, antimicrobial, anti-inflammatory and so on, come from natural sources such as plants and animals, and medicinal chemists very often use them to study their chemical space and improve their biological activity. In fact, several efficient approaches for the formation of aromatic heterocyclic compounds and th…
