Pck1 Deficiency Drives Mitochondrial Dysfunction and Cellular Senescence in Adipocytes

Aging Cell, Volume 25, Issue 4, April 2026.
Phosphoenolpyruvate carboxykinase 1 (Pck1) expression is downregulated in aging white adipose tissue. Adipocyte Pck1 deficiency impairs TCA cycle cataplerosis, causing fumarate accumulation. Excess fumarate disrupts mitochondrial homeostasis, triggers oxidative stress and mtDNA release, activating cGAS–STING signaling and driving inflammaging ...

In Vitro Modeling of Age‐Associated Lipid Mediator's Impact on Vascular Biology Following Platelet Concentrate Transfusion

Aging Cell, Volume 25, Issue 4, April 2026.
Age‐associated LPA affects adverse reactions and alters platelet and endothelial biology following platelet concentrate transfusion. Age‐associated LPC, S1P could be involved in adverse reactions, in platelet and endothelium biology following a PC transfusion.

Tacrolimus Induced Hypertension and Vascular Remodeling Includes Mechanisms of Cellular Senescence—The Protective Effect of Valsartan

Acta Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Calcineurin inhibitors (CNI) such as tacrolimus (Tac) are the first‐line treatment to prevent transplant rejection. However, CNI have adverse effects on blood vessels and renal function, which may be linked to cellular senescence. Valsartan, a common angiotensin II type 1 receptor (AT1R) blocker, exhibits anti‐senescence properties.

IAP Antagonists Selectively Eliminate Therapy‐Induced Senescent Cancer Cells via TNFα‐Independent Apoptosis

Cancer Science, Volume 117, Issue 4, Page 1043-1056, April 2026.
Upon chemotherapy, a subset of cancer cells enters a senescent state, referred to as TIS. When IAP antagonists are administered, TIS cells are selectively eliminated through TNFα‐independent apoptosis. TNFα secreted by TIS cancer cells may also act in a paracrine manner to enhance extrinsic apoptosis in neighboring non‐senescent cancer cells.

First Detection of Lactococcus formosensis subsp. formosensis in Rainbow Trout (Oncorhynchus mykiss) in Europe

Journal of Fish Diseases, Volume 49, Issue 4, April 2026.
ABSTRACT Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis are etiological agents of piscine lactococcosis, a disease reported in Italy since the early 1990s and linked to significant aquaculture losses. To the best of our knowledge, this study reports the first detection of L. formosensis subsp. formosensis in farmed rainbow trout (

Rhizobial motility preference in root colonization of Medicago truncatula

New Phytologist, Volume 250, Issue 1, Page 547-562, April 2026.
Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.
