Table 2. Effects of P18, P24, and Ap2A on the [Ca²⁺]_i and on the content of thapsigargin-sensitive Ca²⁺ stores in CD38^+/- HeLa cells.

Basal [Ca²⁺]_i and thapsigargin-induced Ca²⁺ release (bold numbers) were measured on FURA 2-loaded CD38⁺ and CD38^– HeLa incubated in the absence (control) or in the presence of 1 M dinucleotides for 18 hr. During this time, partial (≤30%) dinucleotide degradation occurred in CD38⁺ cell cultures, with production of Ade and hypoxanthine (see Table 3). Mean results from at least eight different determinations are shown; SD ≤ 15% of the mean value.
