Molecular Mechanism of the βAR Agonist Activity of a β-Blocker.

Development of subtype-selective drugs for G protein-coupled receptors poses a significant challenge due to high similarity between subtypes, as exemplified by the three β-adrenergic receptors (βARs). The βAR agonists show promise for treating the overactive bladder or preterm birth, but their potential is hindered by off-target activation of βAR and βAR. Interestingly, several β-blockers, which are antagonists of the βARs and βARs, have been reported to exhibit agonist activity at the βAR.

The relationship between cancer and biomechanics.

The onset, development, diagnosis, and treatment of cancer involve intricate interactions among various factors, spanning the realms of mechanics, physics, chemistry, and biology. Within our bodies, cells are subject to a variety of forces such as gravity, magnetism, tension, compression, shear stress, and biological static force/hydrostatic pressure. These forces are perceived by mechanoreceptors as mechanical signals, which are then transmitted to cells through a process known as mechanical transduction.
