Abstract

Extrinsic periodic information including physiological cyclical and circadian replacement would affect inevitably a real cell, in this paper we investigate the effect of extrinsic periodic information on intracellular calcium dynamics by means of second-order algorithm for stochastic simulation colored noises. By simulating time evolutions and stationary probability distribution of intracellular Ca2+ concentrations, the results show: (i) intracellular calcium oscillation between cytosol and calcium store shows synchronous and anti-synchronous oscillation as intensity and frequency of extrinsic periodic information vary; (ii) extrinsic periodic information interpolates stability from bistable state → monostable state → bistable state → monostable state as frequency of extrinsic periodic information increases; (iii) extrinsic periodic information interpolates stability from monostable state → bistable state as intensity of extrinsic periodic information increases.
