Profiling of HCAR1 signalling reveals Gαi/o and Gαs activation without β‐arrestin recruitment and the discovery of an allosteric agonist

British Journal of Pharmacology, Volume 183, Issue 10, Page 2219-2235, May 2026.
Abstract Background and Purpose Lactate, historically viewed as a metabolic by‐product, has emerged as a signalling molecule via the G protein–coupled receptor Hydroxycarboxylic Acid Receptor 1 (HCAR1). The receptor is primarily expressed in adipocytes but also found in various other tissues.

G12 signaling through JNK promotes breast cancer cell invasion

The FASEB Journal, 2008
The G12 family of heterotrimeric G proteins has been implicated in such cellular processes as cytoskeletal rearrangements, cell‐cell adhesion and oncogenic transformation. Recently, work done in our laboratory has shown that G12 signaling via Rho induces a striking increase in breast cancer cell invasion in ...

Longitudinal Surveillance of Influenza A Virus Exposure in Wild Boars (Sus scrofa) in Spain (2015–2023): Serologic and Virologic Evidence of Subtype Infections and H5N1 Spillover Risk

Zoonoses and Public Health, Volume 73, Issue 3, Page 191-204, May 2026.
ABSTRACT Introduction Influenza A viruses (IAVs) are responsible for respiratory infections in a wide range of species, including birds, swine and humans. The role of wild boar (Sus scrofa) in IAV epidemiology remains underexplored. Here, we present a longitudinal serologic and virologic surveillance study of wild boars in Spain from 2015 to 2023 ...

Decadal Variability of Eddy Kinetic Energy Along the Eastern Boundary of the Subtropical South Indian Ocean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Using more than three decades (1993–2024) of satellite altimetry and ocean reanalysis, we reassess the dominant timescales of low‐frequency mesoscale eddy variability along the eastern boundary of the subtropical South Indian Ocean. After removal of the seasonal cycle, eddy kinetic energy (EKE) is primarily modulated on decadal timescales (8 ...

The Regulation and Function of Hippo/YAP Pathway in Cancer

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
Hippo/YAP pathway signaling plays critical roles in the progression of multiple cancer types. This review summarizes current knowledge of Hippo/YAP pathway regulation and function in cancer. We discuss the core components of the Hippo/YAP pathway; its crosstalk with other signaling pathways; regulation by non‐coding RNAs; roles of YAP signaling in ...
