DLL3 Archives

Tag: DLL3

DLL3, or Delta-like ligand 3, is a protein that plays a role in the Notch signalling pathway, which is involved in cell development and differentiation. It is particularly known for its high expression in small cell lung cancer (SCLC) and other neuroendocrine tumours, making it a potential therapeutic target. DLL3 is an inhibitory Notch ligand, meaning it can block the signalling pathway.

What is Radioligand Therapy? When you browse the internet, you may see the term "Radioligand Therapy (RLT)" and wondered what it is. There's a simple explanation to what it is; and why you may be seeing more of it. Firstly, you will all be aware of Peptide Receptor Radionuclide Therapy (PRRT), right? Well that is just a type of RLT where the target is somatostatin receptors (SSTR). RLTs can have different targets. You may be seeing the term Radioligand Therapy more because this technology is starting to be used on other cancers but almost always different target routes. The obvious…

Updated 24th September 2025. Introduction There's a lot of Immunotherapy stuff out there! The picture regarding its use in Neuroendocrine Neoplasms is not clear and there is no general roadmap printed. I first heard of Immunotherapy for NETs following attendance at ENETS 2017 in Barcelona. The presentation that sticks out was one given by Dr Matthew Kulke, a well-known NET Specialist in Boston. My reaction to the presentation was one of 'expectation management' and caution i.e. it's too soon to know if we will get any success and when we will get it. He also hinted that it's more likely…

DLL3 Expression in Neuroendocrine Neoplasms – an overview

Clinical Trials and Research, TreatmentDLL3, High grade neuroendocrine neoplasm (NEN), Large cell neuroendocrine carcinoma (LCNEC), Lung NETs, Neuroendocrine carcinoma (NEC), Poorly differentiated, Small cell lung cancer (SCLC)

Updated 20th August 2025 Background - Conventional therapeutic targets for neuroendocrine tumours (NETs) include somatostatin receptors (SSTRs), mammalian Target of Rapamycin (mTOR), Vascular Endothelial Growth Factor (VEGF), and tyrosine kinases. These pathways are crucial for tumour growth, survival, and angiogenesis. The most well known is SSTRs given that most NETs express these and allows targeted therapies such as somatostatin analogues (SSA) and peptide receptor radionuclide therapy (PRRT) to be used. Other targeted therapies like everolimus and sunitinib, which inhibit mTOR and tyrosine kinases respectively. Sunitinib also targets VEGF as does cabozantinib. For neuroendocrine carcinomas (Grade 3 poorly differentiated), targeting has…
