Weekend quote - Steve Cole
"What this study tells us is that doing good and feeling good have very different effects on the human genome, even though they generate similar levels of positive emotion," he said. "Apparently,
the human genome is much more sensitive to different ways of achieving happiness than are conscious minds." (1)
"In effect, according to Cole, the stress reaction requires “mortgaging our long-term health in favor of our short-term survival.” Our bodies, he concluded, are “programmed to turn misery into death.” (2)
"The IL6 gene controls immune responses but can also serve as 'fertilizer' for cardiovascular disease and certain kinds of cancer," said Cole, who is also a member of UCLA's Jonsson Comprehensive Cancer Center and UCLA's Molecular Biology Institute. "Our studies were able to trace a biochemical pathway through which adverse life circumstances -- fight-or-flight stress responses -- can activate the IL6 gene. (3)
"Adverse social conditions can become embedded within the basal transcriptome of primate immune cells within the first 4 mo of life, and they implicate sympathetic nervous system-linked transcription control pathways as candidate mediators of those effects and potential targets for health-protective intervention. " (4)
"Gating of depression-related mortality risk by IL6 genotype pertained only to inflammation-related causes of death and was associated with increased chronic inflammation as indexed by plasma C-reactive protein. Computational modeling of molecular interactions, in vitro biochemical analyses, in vivo animal modeling, and human molecular epidemiologic analyses thus converge in identifying β-adrenergic activation of GATA1 as a molecular pathway by which social adversity can alter human health risk selectively depending on individual genetic status at the IL6 locus.
