Simulation of biochemical dynamics of C a 2 + and P L C in fibroblast cell.

Calcium dynamics is not only responsible for maintaining the framework and functions of the cell but also plays a role in the dynamics of other biochemical systems in the cell. Phospholipase C- γ l ( P L C ) has a crucial role in the function of fibroblast cells. Experiments have shown that P L C and C a 2 + have interdependent dynamics in fibroblast cells. However, no reaction-diffusion model exists for the two-way feedback system dynamics of C a 2 + and P L C in fibroblasts till date. The computational model is designed to investigate the impact of variations in several processes, such as the S E R C A pump, buffer process, source inflow, etc., on the system dynamics of C a 2 + and P L C in fibroblast cells. The computational findings are obtained using finite element techniques, and the consequences of dysregulation in various processes on the spatiotemporal calcium and P L C dynamics in fibroblasts are investigated. The results lead to the conclusion that the effects of buffer, source influx, diffusion, and S E R C A pump can cause fluctuations in the dynamics of C a 2 + and P L C in fibroblasts. Disruptions in these constitutive processes can result in changes in the dynamics of calcium and P L C . Thus, the current model provides new/novel information regarding the precise dysregulatory constitutive systems that regulate calcium and P L C kinetics, such as source inflow, diffusion, S E R C A , and buffer, can be responsible for excessive calcium and P L C concentrations leading to fibrotic illnesses such as cancer and fibrosis.
