Additionally, other in vitro studies have found, under no thermal effects, changes in cell apoptosis in primary cultures of neurons and astrocytes [6], increases in cell proliferation in human astrocytoma cells [7], inhibition of the formation of p53 binding protein 1 (53BP1) in a primary culture of human fibroblasts [8] and a possible activation of fibroblast proliferation [9]. The gene discussed is TP53BP1; the disease is astrocytoma (excluding glioblastoma).
