Abstract:
:p21-activated Kinase 6 (PAK6) is a serine/threonine kinase belonging to the p21-activated kinase (PAK) family. PAK kinases are well-known regulators of a wide variety of cellular functions, including regulation of cytoskeleton rearrangement, cell survival, apoptosis and the mitogen-activated protein kinase signaling pathway. To elucidate the expressions and possible functions of PAK6 in central nervous system (CNS) lesion and repair, we performed a traumatic brain injury (TBI) model in adult rats. Western blot analysis revealed that PAK6 level significantly increased at day 3 after damage, and then declined during the following days. Besides, double immunofluorescence staining showed PAK6 was primarily expressed in the neurons and a few of glial cells in the normal group. While after injury, the expression of PAK6 was increased significantly in the astrocytes and neurons, and the astrocytes had largely proliferated. We also examined the expression of proliferating cell nuclear antigen (PCNA) whose change was correlated with the expression of PAK6. Importantly, double immunofluorescence staining revealed that cell proliferation evaluated by PCNA appeared in many PAK6-expressing cells at day 3 after injury. In addition, injury-induced expression of PAK6 was co-labeled by active caspase-3 during neuronal apoptosis after injury. Collectively, we hypothesized PAK6 may play important roles in CNS pathophysiology after TBI and further research is needed to have a good understanding of its function and mechanism.
