Rational Design of Dual-Targeted Nanomedicines for Enhanced Vascular Permeability in Low-Permeability Tumors.

Designing dual-targeted nanomedicines to enhance tumor delivery efficacy is a complex challenge, largely due to the barrier posed by blood vessels during systemic delivery. Effective transport across endothelial cells is, therefore, a critical topic of study. Herein, we present a synthetic biology-based approach to engineer dual-targeted ferritin nanocages (Dt-FTn) for understanding receptor-mediated transport across tumor endothelial cells.

Ribosomal S6 protein kinase 4 (RSK4), a member of the serine‒threonine kinase family, plays a vital role in the Ras‒MAPK pathway. This kinase is responsible for managing several cellular activities, including cell growth, proliferation, survival, and mobility. In this study, we observed higher RSK4 protein expression in clear cell renal cell carcinoma (ccRCC) than in normal kidney tissue, and the overexpression of RSK4 might predict poor outcomes for ccRCC patients.

Hyperhomocysteinemia (HHcy), characterized by elevated homocysteine (HCys) levels, is associated with increased risks of neurovascular diseases such as stroke or hydrocephalus. HHcy promotes oxidative stress, neuroinflammation, and endothelial dysfunction, disrupting the blood-brain barrier and accelerating neurodegeneration. These processes highlight HCys as both a biomarker and a potential therapeutic target in vascular-related neurological disorders.

Stroke is the leading cause of death and disability worldwide, with ischemic stroke accounting for the majority of these. HBA is the active ingredient in and has potential therapeutic effects on central nervous system diseases. In this study, the cell model of cerebral ischemia was replicated by the culture method of oxygen-glucose deprivation/reoxygenation, and the rat model of vascular dementia was established by the two-vessel occlusion method.

The prevalence of cardiovascular disease varies with sex, and the impact of intrinsic sex-based differences on vasculature is not well understood. Animal models can provide important insights into some aspects of human biology; however, not all discoveries in animal systems translate well to humans. To explore the impact of chromosomal sex on proteomic phenotypes, we used iPSC-derived vascular smooth muscle cells from healthy donors of both sexes to identify sex-based proteomic differences and their possible effects on cardiovascular pathophysiology.
