Potential Protective Role Exerted by Secoiridoids from Olea europaea L. in Cancer, Cardiovascular, Neurodegenerative, Aging-Related, and Immunoinflammatory Diseases [PDF]

open access: yes, 2020
Iridoids, which have beneficial health properties, include a wide group of cyclopentane [c] pyran monoterpenoids present in plants and insects. The cleavage of the cyclopentane ring leads to secoiridoids.

Cardenolide‐Engineered Extracellular Vesicles Augment Drug Uptake and Cytotoxicity in Non‐small Cell Lung Cancer Cells

open access: yesSmall Methods, EarlyView.
Cardenolide‐functionalized extracellular vesicles enable targeted delivery of the chemotherapeutic doxorubicin to A549 lung cancer cells by binding Na+/K+‐ATPase, which is overexpressed in these cells. Surface‐modified, drug‐loaded EVs exhibit enhanced cytotoxicity compared to unmodified EVs and free drug, suggesting this system may lower the effective

Aging‐Derived Alterations in Genomic, Immune, and Metabolic Networks: Implications for Cancer Development and Therapy

open access: yesMedComm – Oncology, Volume 5, Issue 1, March 2026.
Ageing acts as a double‐edged sword in cancer. In the elderly, open chromatin, immunosenescence, and chronic inflammation drive SASP (IL‐6, MMPs), MDSC accumulation and T‐cell suppression, fostering tumor‐promoting microenvironments and limited therapeutic benefit.
