Definitions for nuclear matrix
This page provides all possible meanings and translations of the word nuclear matrix
A framework of fibers extending throughout the nucleus of a cell.
In biology, the nuclear matrix is the network of fibres found throughout the inside of a cell nucleus and is somewhat analogous to the cell cytoskeleton. However, in contrast to the cytoskeleton, the nuclear matrix has been proposed to be a highly dynamic structure, perhaps more like a dynamic sponge with open compartments for free diffusion of molecules in the nucleus. The exact function of this matrix is still disputed, and its very existence has recently been called into question. There is evidence that the nuclear matrix is involved in regulation of gene expression in Arabidopsis thaliana.
U.S. National Library of Medicine
The residual framework structure of the CELL NUCLEUS that maintains many of the overall architectural features of the cell nucleus including the nuclear lamina with NUCLEAR PORE complex structures, residual CELL NUCLEOLI and an extensive fibrogranular structure in the nuclear interior. (Advan. Enzyme Regul. 2002; 42:39-52)
