Can you lengthen telomeres?

Yes, telomeres can be lengthened under certain experimental conditions. The enzyme telomerase can be activated to add repetitive DNA sequences to the chromosome ends, effectively lengthening the telomeres. In laboratory settings, telomerase activation has been used to extend telomere length in cultured cells. However, activating telomerase in humans presents challenges and risks, such as the potential for encouraging cancerous growth. More research is needed to find safe and effective methods to lengthen telomeres in humans.
