Metals May Cause Improper "Flight-Fright" Reactions to Stresses Including Hypoxia~!

Heavy metals have been shown to inhibit the binding of Sp1.  This study shows that "knock down of Egr-1 or Sp1 prevents promoter activation while siRNA knock down of HIF1α inhibits Egr-1 and Sp1 induction. Findings suggest that hypoxia activates the PNMT gene indirectly via HIF1α stimulation of Egr-1 and Sp1. Thus, for stress-induced illnesses where adrenergic dysfunction is implicated, HIF1α may be an "on-off" switch regulating adrenergic responses to stress and a potential target for therapeutic intervention."

Prolactin promotes oxytocin and vasopressin release by activating neuronal nitric oxide synthase

"Prolactin enhances nNOS activity in the PVN and SON, thereby contributing to the regulation of OXT and AVP release. This mechanism likely contributes to the regulation of processes beyond those of female reproduction."

Oxytocin and vasopressin in the medial amygdala differentially modulate approach and avoidance behavior toward illness-related social odor

This study shows an essential role of OT and AVP receptors, especially type 1a, in the MeA in regulating approach/avoidance behaviors, respectively, in social odorant communication.

Polluted Air Increases Obesity Risk In Young Animals

Polluted Air Increases Obesity Risk In Young Animals: "Columbus, OH - Exposure to polluted air early in life led to an accumulation of abdominal fat and insulin resistance in mice even if they ate a normal diet, according to new research."

Biomechanical consequences of rapid evolution in the polar bear lineage.

"continuation of current climate trends could affect polar bears by not only eliminating their primary food source, but also through competition with northward advancing, generalized brown populations for resources that they are ill-equipped to utilize"
