Epac1-selective cyclic-AMP analog 8-pCPT-2'-O-Me-cAMP induces vasodilation on porcine coronary artery in endothelium-independent pathway [PDF]

, 2011
BACKGROUND: Exchange protein directly activated by cyclic AMP (cAMP) 1, Epac1, is a newly discovered cAMP target which acts beyond the classical cAMP effector protein kinase A (PKA).

Decellularized Aged Bruch's Membrane Confers Unique Biochemical Cues to Retinal Pigment Epithelium for In Vitro Modeling of Age‐Related Macular Degeneration

Aging Cell, Volume 25, Issue 5, May 2026.
A Bruchs membrane (BrM) mimic based on aged decellularized BrM was developed and differentially expressed proteins in aged dECM‐BrM that may provide specific biochemical cues fundamental to model AMD in vitro were identified. RPE culture on aged dECM‐BrM developed certain AMD‐like features including reduced TEER and expression of drusen components ...

A role for epithelium‐derived 6‐nitrodopamine on human ureter contractility

British Journal of Pharmacology, Volume 183, Issue 10, Page 2360-2375, May 2026.
Abstract Background and Purpose To investigate the basal release of 6‐nitrodopamine (6‐ND) from human isolated ureter and the role of this novel catecholamine in the ureter contractility. Experimental Approach Ureters from 67 brain‐dead organ donors (40 males and 27 females) were used during kidney transplantation procedures.

Transcriptional Reinforcement of the HER2–RAS Network in HER2‐Positive Gastric Cancer: The RUNX–SOS1 Axis in Context

Cancer Science, Volume 117, Issue 5, Page 1235-1243, May 2026.
RUNX‐dependent transcriptional control of SOS1 reinforces HER2–RAS signaling and may attenuate responses to HER2‐targeted therapies in HER2‐positive gastric cancer. ABSTRACT HER2‐positive gastric cancer represents a distinct molecular subtype characterized by chromosomal instability, variable HER2 amplification, and substantial intratumoral ...

Decoding the Role of Caveolin‐1 in Morphological Diversity and Self‐Renewal of Breast Cancer Cells

Cell Proliferation, Volume 59, Issue 5, May 2026.
The silence of caveolin‐1 (Cav‐1) reproduced the morphological evolutionary behaviour of cancer cells, which is similar to the epithelial‐mesenchymal transition process. And Cav‐1 dependent morphological changes could affect cancer cell self‐renewal capacity through maintaining the morphological stability.

Epigenetic analyses suggest different pathways during pregnancy for development of type 1 diabetes in children with high versus low‐neutral human leukocyte antigen‐risk

Journal of Internal Medicine, Volume 299, Issue 5, Page 570-586, May 2026.
Abstract Background and objective The development of Type 1 diabetes (T1D) is shaped by genetic predisposition and epigenetic regulation. Human leukocyte antigen (HLA) risk alleles are major genetic determinants, but the epigenetic landscape in relation to disease onset remains unclear.
