The tandemly organized highly repetitive satellite DNA is the main DNA component of centromeric/pericentromeric constitutive heterochromatin. For almost a century, it was considered as "junk DNA," only a small portion of which is used for kinetochore formation. The current review summarizes recent data about satellite DNA transcription. The possible(More)
One of the hypotheses suggests that test cells play a part in a larval tunic formation like morula cells in adult ascidians. It was shown that the antibodies against morula cell proteins of 26 and 48 kDa of the ascidian Styela rustica react on the paraffin sections with both the granules of morula cells and test cells of ascidians S. rustica and Boltenia(More)
Abstract—The expression of the DDX5 protein (RNA helicase p68) in cells correlates with processes of proliferation and differentiation. However, involvement of the protein in these processes has not been proven yet. In this paper, we have studied the effect of DDX5 protein inactivation (with small interfering RNAs) on the proliferation of Jurkat cell line(More)
The expression of DDX5 protein (RNA-helicase p68) correlates with processes of proliferation and differentiation. However there is no direct evidence of involvement of the protein in these processes. In present work, we studied the influence of DDX5 protein inactivation by si-RNA on the proliferation of Jurkat cells and dynamic of DDX5 expression during(More)
