TABLE 3.
Ca2+ registrations in SW620 cells pretreated with DHA (70 μM) at time points indicated: SW620 cells stimulated with ATP, 1μM
| Pretreatment | # Cells | Baseline [Ca2+], nM | Maximal [Ca2+] Increase, nM | Decline of the Response | 
|---|---|---|---|---|
| None (control) | 103 | 123 (± 4.1) | 247 (± 10.6) | 2.07 (± 0.09) | 
| DHA 24 h | 85 | 141 (± 4.7)a | 238 (± 14.1) | 1.61 (± 0.07)a | 
| 2. EGTA | 81 | 103 (± 3.7)a | 259 (± 18.2) | 2.51 (± 0.14)a | 
| EGTA, DHA 24 h | 73 | 105 (± 3.8)a,b | 227 (± 17.3) | 2.11 (± 0.12)a,b | 
EGTA, ethylene glycol tetraacetic acid. After 30 s of [Ca2+] registration ATP (1μM) (Sigma-Aldrich) or vehicle was added. Maximal [Ca2+] increase is calculated as difference between baseline and peak [Ca2+] in the responding cells. The decline of the response is quantified as the ratio between peak [Ca2+] and [Ca2+] at the end of the registration (180 s). Registrations are depicted in Fig. 4D. The data are presented as means with standard errors (± SEM).
Significantly different from control (P < 0.05).
Significantly different from DHA 24 h (÷ EGTA) (P < 0.001).
