“老”是一種病嗎? Nature Reviews Drug Discovery 4, 569 -580, 2005
Accumulation of germ-line mutations with late-acting deleterious effects 在平均年齡 30歲的族群中累積了許多 60歲才會發作的基因突變 …the forces of natural selection weakens with increasing age …. If a genetical disaster… happens late enough in individual life, its consequences may be completely unimportant. Even in such a crude and unqualified form, this dispensation may have a real bearing on the origin of innate deterioration with increasing age. Medawar, 1952

Cellular senescence Human diploid fibroblast has limited replicative life span, termed replicative senescence or cellular senescence. Human diploid fibroblasts can divide ~60 -80 times. Experimental Cell Vol. 25 585 -621, 1961 周成功
Young vs. senescent fibroblasts • Senescent cells are generally larger, less motile, decreased saturation density. • Senescent cell is different from the quiescent cell in G 0. Senescence is irreversible process whereas G 0 cells can reenter cell cycle upon induction. • Senescent cells resist apoptosis, this may explain why senescent cells are not cleared and thus accumulate with age. Experimental Cell Research 212, p 167 -175, 1994

Human telomere shortening during replication Nature 345, 458 – 460; May 1990
Is cellular senescence the same as biological aging? • Cells cultured from old donors tend to senesce after fewer population-doublings than cells from young cell. • Interspecies comparison suggests that cell replicative life span and biological life span is genetically related.
Correlation between telomere length and human aging Nature 346, p. 866 – 868; Aug 1990
Cells from long-lived species are capable of replicating more times Sci Am. 1968 Mar; 218(3): 32 -7
What is the cause of Dolly’s death? • Dolly was cloned in 1997. • Analysis of telomere lengths in Dolly indicates that Dolly’s telomere length is similar to normal six-year-old sheep (1999). • Dolly die on 14 Feb, 2003 Toni Barros Dolly, 1997 -2003
Werner Syndrome • Autosomal recessive; Life Span in Years: 60 • Loss of WRN, a Rec. Q family helicase. • Reduced replicative life span of cultured cells. Increased mutation rate, particularly DNA deletions. Rapid telomere shortening during cellular replicative life span.
