Some participants argued that it can provide some benefit, depending on the individual patient's symptom profile, while others disagreed with the practice, citing the lack of alpha receptors to target in that setting.
Alpha receptors are the ones that cause relaxation of smooth muscles around bronchial tubes when stimulated, while stimulation of beta receptors increases heart activity.
Wright explains that estrogen stimulation of alpha receptors tends to increase cell proliferation, while beta receptors tend to decrease it.
These nine articles describe some of the work being done to differentiate markers and use their presence to detect and treat a range of cancers, addressing the characterization of breast cancer subtypes in a large retrospective study, intraocular lymphoma markers, polymorphisms in genes associated with certain T-cell lymphomas, tumor antigens that are markers of minimal residual disease in acute myeloid leukemia, thyroid tumor markers, activity and expression of dipeptidyl peptidase IV and cathepsin H in human cutaneous melanoma compared to other common cancers, melanoma inhibitory activity as a serological marker in metastic melanoma, and the promise (or myth) of the tumor necrosis factor alpha receptors p55 and p75 in ovarian cancer detection.
