(A) Kaplan-Meyer survival curves of the indicated cohorts. Arrows indicate time of blood extraction.
(B and C) The mean telomere length (B) and percentage of short telomeres (C) were determined by HT-QFISH on white blood cells (n, number of mice). Values are given as average ± SEM, and statistical significance was determined by one-tailed Student’s t test. (B) From left to right (average ± SEM): ± 1.633, ± 1.322, ± 1.118, ± 2.241, ± 2.049, 46.06 ± 2.142, ± 2.053, ± (C) From left to right (average ± SEM): ± , ± , ± 1.257, ± 3.552, ± 1.078, ± 1.237, ± 1.798, 21.93 ±
(D and E) Adjustment of mean telomere length (D) and percentage of short telomeres (E) with aging to a linear or quadratic model. Second-order polynomial adjustment (quadratic) was used for the nonlinear fit model.

The Rate of Increase in the Percentage of Short Telomeres and the Rate of Telomere Shortening Predicts Mouse Longevity
(A–C) The percentage of short telomeres (<15 kb; A and C) and mean telomere length (B and C) were determined by HT-QFISH on white blood cells (see Figure 1). Linear regression lines were calculated for the values obtained for the rate of increase in the percentage of short telomeres and for the rate of mean telomere length shortening (kb/month) versus lifespan (weeks). (A) Rate of increase in the percentage of short telomeres (<15 kb) per month versus lifespan (weeks). (B) Rate of mean telomere length shortening (kb/month) versus the rate of increase in the percentage of short telomeres (per month). (C) Rate of mean telomere length shortening (kb/month) versus the rate of increase in the percentage of short telomeres (<15 kb) per month. The slope of each regression line is indicated.

The Rate of Increase in the Percentage of Short Telomeres and the Rate of Telomere Shortening Is a Predictor of Mouse Longevity, Related to Figure 2
(A and B) The rate of increase in percentage of short telomeres (<15 kb; A) and mean telomere length (B) were determined by HT-QFISH on white blood cells from the indicated mice cohorts at the indicated time points (see Figure 1). Linear regression lines were calculated for the values obtained for the rate of increase in the percentage of short telomeres and for the rate of mean telomere length shortening (kb/month) versus lifespan (weeks). (A) Rate of increase in the percentage of short telomeres (<15 kb) per month versus lifespan (weeks). (B) Rate of mean telomere length shortening (kb/month) versus increase in the percentage of short telomeres (per month). Only results from TgTERT mice for which the four time points were measured are plotted.
