Article Synopsis
- Plants from the Asteraceae family are popular for their economic, medicinal, and ornamental uses, but the specific properties of a hybrid species (×) from South Korea have not been well-studied.
- This research focused on analyzing phenolic acid levels in different parts of × and tested how growth at various temperatures (20, 25, and 30 °C) affected these levels.
- The findings revealed that chlorogenic acid was most abundant in the leaves and that while growth characteristics remained similar at different temperatures, 30 °C was optimal for producing phenolic acids.
α2-Adrenergic blockade mimics the enhancing effect of chronic stress on breast cancer progression.
Psychoneuroendocrinology
January 2015
Experimental studies in preclinical mouse models of breast cancer have shown that chronic restraint stress can enhance disease progression by increasing catecholamine levels and subsequent signaling of β-adrenergic receptors. Catecholamines also signal α-adrenergic receptors, and greater α-adrenergic signaling has been shown to promote breast cancer in vitro and in vivo. However, antagonism of α-adrenergic receptors can result in elevated catecholamine levels, which may increase β-adrenergic signaling, because pre-synaptic α2-adrenergic receptors mediate an autoinhibition of sympathetic transmission.
