Efficacy of beta 1-adrenergic receptors is lower than that of beta 2-adrenergic receptors. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1993
We investigated the relative activity at which fully occupied human beta 1- and beta 2-adrenergic receptors (beta 1AR and beta 2AR) activate the stimulatory G protein (Gs)/adenylyl cyclase (AC) system in isolated membranes. The receptors were cloned and coexpressed in permanent cell lines at beta 1/beta 2 ratios that varied from 1:2 to 3:1 and at total

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Impact of noradrenergic inhibition on neuroinflammation and pathophysiology in mouse models of Alzheimer’s disease

open access: yesJournal of Neuroinflammation
Norepinephrine (NE) modulates cognitive function, arousal, attention, and responses to novelty and stress, and it also regulates neuroinflammation. We previously demonstrated behavioral and immunomodulatory effects of beta-adrenergic pharmacology in ...

BETA-ADRENERGIC RECEPTORS IN VARIOUS ORGANS

open access: yesJapanese Journal of Pharmacology, 1970
The concept of two adrenergic receptor mechanisms or α- and β-adrenergic receptor systems, originally postulated by Ahlguist (1) is presently accepted. Furchgott (2) has presented evidence suggesting that there may be different types of receptors in the β- class.

Bioprinting High‐Cell‐Density Cardiac Tissue Constructs With Sustained Contractile Function

open access: yesAdvanced Healthcare Materials, EarlyView.
Contractile cardiomyocytes in 3D culture provide insights into the behavior of the heart. Combining a 3D bioprinting approach with a multi‐electrode array allows the development of the 3D culture to be monitored over time, and matured cultures allow the effect of drugs on cardiac function to be modelled, replicating effects seen in clinical application.

Beta-Blockers and Cancer: Where Are We?

open access: yesPharmaceuticals, 2020
Cancer is one of the leading causes of death worldwide. After diagnosis, cancer treatment may involve radiotherapy, chemotherapy, and surgery. Several of the approaches used to treat cancer also attack normal cells and, thus, there is the need for more ...

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

open access: yesAdvanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity

open access: yesAdvanced Science, EarlyView.
We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

Beta-adrenergic receptor blockers effects on the antinociceptive action of imipramine against thermal induced pain in albino mice

open access: yesLibyan International Medical University Journal, 2016
Introduction: Tricyclic antidepressant have been shown to be effective in treatment of pain of varying etiology, monoaminergic system seems to be implicated in this phenomena.

Agnuside Stabilizes the Complex I Assembly Factor NDUFAF6 to Reinforce Mitochondrial Efficiency and Thermogenic Responsiveness

open access: yesAdvanced Science, EarlyView.
ABSTRACT Brown and beige adipocytes dissipate energy as heat, yet effective strategies to enhance their mitochondrial efficiency remain limited. Here, we identify Agnuside (AGN) as a selective stabilizer of the complex I assembly factor NDUFAF6. AGN directly binds cytosolic NDUFAF6, suppresses its ubiquitination, prolongs its half‐life, and facilitates
