Hederagenin Attenuates Cardiac Remodeling by Targeting Phosphodiesterase 9A

open access: yesPhytotherapy Research, Volume 40, Issue 5, Page 2710-2729, May 2026.
ABSTRACT Background and Aim New therapeutic strategies for heart failure are urgently needed. The protective effects of cyclic guanosine monophosphate (cGMP)—protein kinase G (PKG) pathway on heart have been widely reported. Despite phosphodiesterase 9A (PDE9A) inhibitors combating cardiac remodeling, clinically available drugs are lacking. Hederagenin

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1399-1420, May 2026.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...
