  1. The mass, protein, and nuclei number values shown in Table 2 were divided by the observed high density doubling times from Table 1 (the mass, protein, and nuclei numbers were measured in this density range) to obtain the approximate increases in mass, protein, and nuclei per hour. All values are means ± SEM's from three or more independent assays. A ** indicates that the value was significantly different from the wild-type value with p < 0.01 (1-way ANOVA, Dunnett's test).
