Nuclear membrane disassembly and rupture.
The nuclear envelope consists of two membranes traversed by nuclear pore complexes. The outer membrane is continuous with the endoplasmic reticulum. At mitosis nuclear pore complexes are dismantled and membranes disperse. The mechanism of dispersal is controversial: one view is that membranes feed into the endoplasmic reticulum, another is that they vesiculate. Using Xenopus egg extracts, nucle...
متن کاملpremature rupture of membrane (prom)
for diagnosing prom, the need has been acutely felt for special care in obstetrics. coordinated management for patient care between the clinician and midwives is the custom in several obstetric care centers. diagnosis and treatment by the physician has greatly facilitated the work of midwives, to the extent that they now play an important role in the special nursing of women in solving obstetri...
متن کاملNuclear envelope breakdown in mammalian cells involves stepwise lamina disassembly and microtubule-drive deformation of the nuclear membrane.
We have studied nuclear envelope disassembly in mammalian cells by morphological methods. The first signs of nuclear lamina depolymerization become evident in early prophase as A-type lamins start dissociating from the nuclear lamina and diffuse into the nucleoplasm. While B-type lamins are still associated with the inner nuclear membrane, two symmetrical indentations develop on antidiametric s...
متن کاملMicrocanonical Lattice Gas Model for Nuclear Disassembly
Microcanonical calculations are no more difficult to implement than canonical calculations in the Lattice Gas Model. We report calculations for a few observables where we compare microcanonical model results with canonical model results. 25.70.Pq, 24.10.Pa, 64.60.My Typeset using REVTEX 1
متن کاملRNA-dependent disassembly of nuclear bodies.
Nuclear bodies are membraneless organelles that play important roles in genome functioning. A specific type of nuclear bodies known as interphase prenucleolar bodies (iPNBs) are formed in the nucleoplasm after hypotonic stress from partially disassembled nucleoli. iPNBs are then disassembled, and the nucleoli are reformed simultaneously. Here, we show that diffusion of B23 molecules (also known...
