DISP3/PTCHD2 function in neural cells
Konířová, Jana ; Bartůněk, Petr (advisor) ; Anděrová, Miroslava (referee) ; Pacherník, Jiří (referee)
DISP3 protein, also known as PTCHD2, belongs to the PTCHD family of proteins, which contain a sterol-sensing domain in their structure. The expression of the Disp3 gene is high in neural tissues and is regulated by thyroid hormone. The DISP3 gene is associated with development and progression of certain types of tumors, as well as with development of some neural pathologies. Neural stem cells also display high expression of the Disp3 gene. Neural stem cells are defined by their capability to self-renewal and capacity to differentiate into the basic types of neural cells - neurons, astrocytes, and oligodendrocytes. Precise regulation of the balance between proliferation and differentiation of neural stem cells is crucial for development of the central nervous system and its subsequent proper functioning, and disruption of this balance may lead to development of various pathologies. In this work we mainly focused on describing the function of the DISP3 protein in neural cells and tissues. We have shown that during differentiation of neural stem cells, the expression of the Disp3 gene is significant decreased. Furthermore, we have found that in neural stem and progenitor cells, the increased expression of the Disp3 gene promotes their proliferation. Moreover, when Disp3 expression was disrupted, the...
