Using immunofluorescence and live-cell imaging, researchers were recently able to determine the mechanism underlying the repairing mechanism of the nuclear envelope, which play a key role in various ...

All living cells harbor nuclei - key biological structures that play an important role in information storage, retrieval, and duplication of genetic information. In mammals, these nuclei possess the ...

“What used to be a cell with components, the reality of which was often a matter of dispute and functions as a rule unknown is now a system of great organizational sophistication with units for the ...

Mitosis in vertebrates involves nuclear-envelope breakdown and dispersal. On completion of chromatid segregation, disassembled nuclear-envelope components are reused to form nuclear membranes in the ...

In 2022 alone, over 20 million people were diagnosed with cancer, and nearly 10 million died from the disease, according to the World Health Organization. While the reaches of cancer are massive, the ...

Context matters. It's true for many facets of life, including the tiny molecular machines that perform vital functions inside our cells. Scientists often purify cellular components, such as proteins ...

Fluorescence microscopy illustrates immune cell–mediated extraction of nuclear DNA from dying cells, highlighting a newly identified process called nucleocytosis. Over the years, cell biology has ...

Nuclear pore complexes (NPCs) allow for the transport of cargo across the nuclear envelope between the nucleus and cytoplasm. They are composed of roughly thirty different nucleoporins that are ...

All living cells harbor nuclei—key biological structures that play an important role in information storage, retrieval, and duplication of genetic information. In mammals, these nuclei possess the ...

In a recent landmark study, scientists have unveiled how HIV-1 penetrates the cell's nuclear barrier—a discovery that could reshape antiviral strategies. The research, led by Professor Peijun Zhang, ...
