Purpose The use of prophylactic α-adrenergic receptor antagonists prior to surgery is associated with reduced postoperative urinary retention. However, α-adrenergic receptor antagonists have been associated with intraoperative floppy iris syndrome (IFIS).

Receptor-mediated enhancement of beta adrenergic drug activity by ascorbate in vitro and in vivo. [PDF]
RATIONALE: Previous in vitro research demonstrated that ascorbate enhances potency and duration of activity of agonists binding to alpha 1 adrenergic and histamine receptors.

Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Recent preclinical studies have associated beta-adrenergic receptor (β-AR) signaling with breast cancer pathways such as progression and metastasis. These findings have been supported by clinical and epidemiological studies which examined the effect of ...

Long‐Term Efficacy of Immunotherapy in Autoimmune Autonomic Ganglionopathy—A 10‐Year Follow Up Study
ABSTRACT Objective Autoimmune autonomic ganglionopathy (AAG) is a rare but potentially treatable cause of severe autonomic failure. Evidence guiding long‐term immunotherapy, treatment sequencing, and residual autonomic impairment is limited. We evaluated long‐term treatment response, residual autonomic dysfunction, and relapse patterns in patients with

Adrenergic Autoantibody‐Induced Postural Tachycardia Syndrome in Rabbits
Background Previous studies have demonstrated that functional autoantibodies to adrenergic receptors may be involved in the pathogenesis of postural tachycardia syndrome.

β-Adrenergic agonist and antagonist regulation of autophagy in HepG2 cells, primary mouse hepatocytes, and mouse liver. [PDF]
Autophagy recently has been shown to be involved in normal hepatic function and in pathological conditions such as non-alcoholic fatty liver disease. Adrenergic signalling also is an important regulator of hepatic metabolism and function.

Role of β-adrenergic receptors in insulin resistance: Induction or protection?
β Adrenergic receptors, in particular β2 subtype, are key regulators of glucose homeostasis. Previous studies showed that activation of hepatic and adipose tissue β adrenergic receptors mediates insulin desensitizing effects.
