Uncovering the genetic basis of ALT (Alternative Lengthening of Telomeres) — Harold Silva

Dr Haroldo Silva from SENS talks about ALT cancer in this short film.
As normal cells divide, the ends of their chromosomes (telomeres) progressively shorten until eventually the cells reach senescence or undergo apoptosis. Cancers, which disproportionally kill more individuals in the 65 years or above age group, often overcome this built-in replication limit by expressing the enzyme telomerase.
