  In this paper the heat signaling in microtubules (MT) is investigated. It is
argued that for the description of the heat signaling phenomena in MT, the
hyperbolic heat transport (HHT) equation must be used. It is shown that HHT is
the Klein-Gordon (K-G) equation. The general solution for the K-G equation for
MT is obtained. For the undistorted signal propagation in MT the Heisenberg
uncertainty principle is formulated and discussed.
  Key words: Microtubules; Heat signaling; Klein-Gordon equation; Heisenberg
principle.
