Xenohormesis: Sensing the Chemical Cues of Other Species
نویسندگان
چکیده
Many plant molecules interact with and modulate key regulators of mammalian physiology in ways that are beneficial to health, but why? We propose that heterotrophs (animals and fungi) are able to sense chemical cues synthesized by plants and other autotrophs in response to stress. These cues provide advance warning about deteriorating environmental conditions, allowing the heterotrophs to prepare for adversity while conditions are still favorable.

What is Xenohormesis?
Polyphenols such as resveratrol and quercetin, which are produced by stressed plants, activate sirtuin enzymes and extend the lifespan of fungi and animals, ostensibly by mimicking the beneficial effects of caloric restriction. This observation raises an interesting question: Why should foreign molecules that are non-nutritive and seemingly unrelated to any endogenous molecule modulate the same...
متن کاملThe Possibility of Selective Adsorption and Sensing of the Noble Gaseous Species by the C20 Fullerene, the Graphene Sheets, and the N4B4 Cluster
There are only a handful reports about the sensor systems having the ability of detecting the existence of the noble gases. Chemical reluctance of these gaseous species causes them to have no chemical interactions like hydrogen bonding with the chemically designed nano-sized sensors. Noble gasses usually have no atomic charges nor do change the total polarity of the molecular sensor systems. Th...
متن کاملQuorum Sensing in Microbial Virulence
Cell-to cell communication occurs via a signaling pathway referred to as quorum sensing. There are four main types of these systems according to the chemical nature of signal molecules used by microorganisms to elicit expression of target genes in response to environmental stimuli or need of microbial communities. Type I system acts by using acyl homoserine lactones as signals to trigger the ex...
متن کاملBenthic Biotopes Remote Sensing Using Single Beam Acoustics on the South Coast of the Qeshm Island, the Persian Gulf
The study presents the result of a new attempt for benthic biotopes remote sensing in the southern coast of the Qeshm Island in the Persian Gulf. This survey site covers approximately 233 km2 in water depth between five and 25 m. Bathymetric data was derived from the single beam survey and grab stations, underwater video and photos were undertaken as ground-trusthing. The acoustic results showe...
متن کاملSpontaneous Adsorption, and Selective Sensing of CO, and CO2 Greenhouse Gaseous Species by the more Stable Forms of N4B4 Clusters
Carbon oxide gaseous species are potentially considered as pollutants of the atmosphere of earth; especially, carbon monoxide and carbon dioxide which are of the well-known carbon oxids, play an effective role in the greenhouse gas emissions. Moreover, these species could initiate or handle some chain reactions in the troposphere that lead to emergence of some secondly air pollutants which may ...
