... glioblastoma multiforme, she says. Telomeres, the structures that cap the end of cellular chromosomes, have been linked to both the aging process and cancer development. Telomerase is an enzyme that helps regulate the length of telomeres, and in normal cells, it is not generally active past fetal development. ...Technique may speed drug production, reduce costs and waste
