The structure of human telomerase reverse transcriptase (hTERT). Human TERT contains four key domains: the telomerase essential N-terminal (TEN) domain; the TERT RNA binding (TRB) domain; the reverse transcriptase (RT) domain and the C-terminal extension (CTE) domain.
Researchers from several institutions, including, UCLA, Boston University, Stanford University and the Institute for Aging Research at Hebrew SeniorLife, analyzed blood samples from nearly 10,000 people to find that genetic markers in the gene responsible for keeping telomeres (tips of chromosomes) youthfully longer, did not translate into a younger biologic age as measured by changes in proteins coating the DNA.
DNA methylation age is a biomarker of chronological age and predicts lifespan, but its underlying molecular mechan...
