BACKGROUND Preclinical studies have demonstrated that β-adrenergic receptor antagonists could improve the prognosis of breast cancer. However, the conclusions of clinical and pharmacoepidemiological studies have been inconsistent. This review was conducted to re-assess the relationship between beta-adrenoceptor blockers and breast cancer prognosis. MATERIALS AND METHODS The literature was sea...
Sympathetic efferent nerves are present in tendons, but their function within tendon is unknown. alpha(1)-Adrenoceptors are expressed by a variety of cell types. In the presence of norepinephrine (NE), adrenoceptors activate G(q/11) signaling pathways that subsequently increase intracellular Ca(2+) concentration ([Ca(2+)](ic)). It was hypothesized that avian tendon cells express functional adre...
Antipsychotic drugs with greater efficacy and tolerance have been sought and studied in recent years. Some of them could be used in new treatment strategies to replace the D(2) receptor antagonism induced by classic neuroleptics such as haloperidol. The development strategies in this field are not only focused on discovering specific antagonists of one subtype of dopaminergic receptor, but on t...
Benign prostatic hyperplasia (BPH) is characterized by stromal cell proliferation and contraction of the periurethral smooth muscle, causing lower urinary tract symptoms. Current BPH treatment, based on monotherapy with a1A-adrenoceptor antagonists, is helpful for many patients, but insufficient for others, and recent reports suggest that stimulation of a1D-adrenoceptors and 5-hydroxytryptamine...
