Roles of estrogen receptor-alpha in mediating life span: the hypothalamic deregulation hypothesis.
In several species caloric restriction (CR) extends life span. In this paper we integrate data from studies on CR and other sources to articulate the hypothalamic deregulation hypothesis by which estrogen receptor-alpha (ER-α) signaling in the hypothalamus and limbic system affects life span under the stress of CR in mammals. ER-α is one of two principal estrogen-binding receptors differentially expressed in the amygdala, hippocampus, and several key hypothalamic nuclei: the arcuate nucleus (ARN), preoptic area (POA), ventromedial nucleus (VMN), antero ventral periventricular nucleus (AVPV), paraventricular nucleus (PVN), supraoptic nucleus (SON), and suprachiasmatic nucleus (SCN). Estradiol signaling via ER-α is essential in basal level functioning of reproductive cycle, sexually receptive behaviors, physiological stress responses, as well as sleep cycle, and other nonsexual behaviors. When an organism is placed under long-term CR, which introduces an external stress to this ER-α signaling, the reduction of ER-α expression is attenuated over time in the hypothalamus. This review paper seeks to characterize the downstream effects of ER-α in the hypothalamus and limbic system that affect normal endocrine functioning

Religious Transhumanism and Its Critics
Why do representatives of different religious traditions find the transhumanist vision of the future not only theologically compatible but even inspiring? Transhumanism is a global movement seeking radical human enhancement. The trans in transhumanism marks the transition from the present stage in human evolution into the future, namely, post-human existence. Containing chapters written by adherents to a variety of religious traditions, Religious Transhumanism and Its Critics provides first-hand testimony to the value of the transhumanist vision perceived by the religious mind. In addition, the contributors critique both secular and religious transhumanism in light of realistic science and commitment to social justice.https://scholarcommons.scu.edu/faculty_books/1556/thumbnail.jp
