Nuclear lamins in cancer.
Dysmorphic nuclei are commonly seen in cancers and provide strong motivation for studying the main structural proteins of nuclei, the lamins, in cancer. Past studies have also demonstrated the significance of microenvironment mechanics to cancer progression, which is extremely interesting because the lamina was recently shown to be mechanosensitive. Here, we review current knowledge relating ca...
متن کاملNuclear Lamins a and B1
At the end of mitosis, the nuclear lamins assemble to form the nuclear lamina during nuclear envelope formation in daughter cells. We have fused A- and B-type nuclear lamins to the green fluorescent protein to study this process in living cells. The results reveal that the A- and B-type lamins exhibit different pathways of assembly. In the early stages of mitosis, both lamins are distributed th...
متن کاملA role for nuclear lamins in nuclear envelope assembly
The molecular interactions responsible for nuclear envelope assembly after mitosis are not well understood. In this study, we demonstrate that a peptide consisting of the COOH-terminal domain of Xenopus lamin B3 (LB3T) prevents nuclear envelope assembly in Xenopus interphase extracts. Specifically, LB3T inhibits chromatin decondensation and blocks the formation of both the nuclear lamina-pore c...
متن کاملNuclear lamins: key regulators of nuclear structure and activities
The nuclear lamina is a proteinaceous structure located underneath the inner nuclear membrane (INM), where it associates with the peripheral chromatin. It contains lamins and lamin-associated proteins, including many integral proteins of the INM, chromatin modifying proteins, transcriptional repressors and structural proteins. A fraction of lamins is also present in the nucleoplasm, where it fo...
