Atm PROTEIN CAN SWITCH OFF THE DNA DAMAGE SIGNAL IN A p53 MODEL<br />
If Λ ≤ 0 then change of sign of ∆ makes a bifurcation which is showed<br />
through cases ( a ),( b)<br />
and (c)<br />
(see the table A and the figure 6). This proves part<br />
(1) of the theorem .<br />
If Λ > 0 then change of the sign of Ω makes a bifurcation which is<br />
