A new study of 15,000 people world-wide has identified 1,450 genes tied with the aging process and has indicated that our aging process is tied to changes in how these genes are expressed (i.e., how genes => RNA => protein transcription occurs). Using this information, the researchers were able to devise a measure of “biological age”, often different than chronological age. And in particular, they were able to observe that individuals whose “biological age” is older than their chronological age tended to suffer higher cholesterol levels, blood pressure and body mass index (BMI). Links to two articles on the study, together with the study itself, have been posted in Aging.
