How plants learned to respond to changing environments

bianjie submitted, created time 1 year 5 months (www.eurekalert.org)

A team of John Innes Center scientists lead by Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment. Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. They can also repress growth when their environment is not favorable. This involves many complex signalling pathways which are integrated by the plant growth hormone gibberellin.

Hormone that signals fullness also curbs fast food consumption and tendency to binge eat

bioman submitted, created time 1 year 7 months (www.eurekalert.org)

The synthetic form of a hormone previously found to produce a feeling of fullness when eating and reduce body weight, also may help curb binge eating and the desire to eat high-fat foods and sweets. The findings on fast food consumption and binge eating tendencies are based on a 6-week research study of 88 obese individuals.

The research, entitled ramlintide treatment reduces 24-hour caloric intake and meal sizes and improves control of eating in obese subjects, appears in the online edition of the American Journal of Physiology-Endocrinology and Metabolism.

Clubbers who take the "love drug" ecstasy really might be "loved up". Studies in rats suggest the drug causes a brain surge of oxytocin - the hormone that helps bond couples, as well as mothers to their babies.

Postmenopausal Hormone Therapy and Risk of Cardiovascular Disease by Age and Years Since Menopause

amanda submitted, created time 1 year 9 months (jama.ama-assn.org)

"Women who initiated hormone therapy closer to menopause tended to have reduced CHD risk compared with the increase in CHD risk among women more distant from menopause, but this trend test did not meet our criterion for statistical significance. A similar nonsignificant trend was observed for total mortality but the risk of stroke was elevated regardless of years since menopause. These data should be considered in regard to the short-term treatment of menopausal symptoms. "

The prolactin family: effectors of pregnancy-dependent adaptations

athena submitted, created time 1 year 9 months (www.sciencedirect.com)

"Prolactin (PRL) is a hormone involved in many biological functions. In some species, there is a family of PRL-related genes; such is the case in the mouse and rat. The actions of members of the PRL family can be distinguished based on the involvement of the PRL receptor signaling pathway (classical versus nonclassical). Recent insights into the biology of the PRL family have been derived from mouse mutagenesis studies. There is compelling evidence suggesting that the PRL family contributes to the regulation of pregnancy-dependent adaptations to physiological stressors. "

Membrane-Initiated Actions of Estrogens in Neuroendocrinology: Emerging Principles

badboy submitted, created time 1 year 9 months (edrv.endojournals.org)

"Hormonal ligands for the nuclear receptor superfamily have at least two interacting mechanisms of action: 1) classical transcriptional regulation of target genes (genomic mechanisms); and 2) nongenomic actions that are initiated at the cell membrane, which could impact transcription. Although transcriptional mechanisms are increasingly well understood, membrane-initiated actions of these ligands are incompletely understood. Historically, this has led to a considerable divergence of thought in the molecular endocrine field. "

'Trust' hormone helps mind-reading too

THE trust hormone, it seems, is also the mind-reading hormone. A sniff of oxytocin, which underpins social attachment among animals, also turns out to improve men's ability to read other people's emotions.
