Background: To detect the expression of Nesprin-1 in aortic dissection (AD) in patients and to investigate the role of Nesprin-1 in the pathogenesis of AD in a mouse model.

Methods: Blood and tissue specimens from AD patients were collected. The expression of Nesprin-1 in tissues from AD patients and non-AD patients with heart disease was studied by western blotting and quantitative real-time polymerase chain reaction (qRT-PCR). In addition, the expression and distribution of Nesprin-1 in AD and sham mice were compared in an induced AD mouse model, and detected by immunohistochemistry and qRT-PCR.

Results: Immunoblotting and qRT-PCR both showed that the expression of Nesprin-1 was significantly higher in AD versus control patients. An animal model of AD was established by continuous injection of Ang II into ApoE mice. The expression of Nesprin-1 in aortic tissue of AD mice was higher than that of sham-operated mice as determined by immunohistochemistry. qRT-PCR showed that Nesprin-1 gene expression in aorta of AD mice was higher than that of sham-operated mice.

Conclusions: An increased expression of Nesprin-1 was associated with AD, and hence Nesprin-1 may be involved in the pathogenesis of ADs. Preliminary findings suggest that Nesprin-1 may be a therapeutic target for the treatment of AD.

Article Synopsis
  • Dilated cardiomyopathy is a serious heart condition where the heart chambers enlarge and weaken, causing difficulty in pumping blood and heart failure.
  • Nesprins, which are proteins that connect the nuclear envelope and cytoskeleton, are important for maintaining heart muscle structure and function, especially in the context of dilated cardiomyopathy.
  • Mutations in genes related to Nesprin-1 and Nesprin-2 have been linked to this heart disorder, suggesting their critical role in cardiac health and potential targets for new treatments.

Nesprin proteins, which are components of the linker of nucleoskeleton and cytoskeleton (LINC) complex, are located within the nuclear envelope and play prominent roles in nuclear architecture. For example, LINC complex proteins interact with both chromatin and the cytoskeleton. Here, we report that the Drosophila Nesprin MSP300 has an additional function in autophagy within larval body wall muscles.

Article Synopsis
  • Nuclear architectural abnormalities are characteristic of nuclear envelopathies caused by mutations in nuclear envelope proteins, particularly the lamin A/C gene, leading to diseases like muscular dystrophies and progeria.
  • A mouse model with the Lmna H222P mutation showed severe cardiomyopathy and abnormal nuclei in skeletal muscle, with myoblasts and myotubes exhibiting different degrees of nuclear shape abnormalities during in vitro differentiation.
  • Myonuclei from H222P mice displayed persistent deformities, with a significant portion having blebs, while maintaining some nuclear envelope protein localization, indicating disruptions in nuclear structure without triggering DNA damage or apoptosis.

Article Synopsis
  • Nesprins are proteins that connect the nucleoskeleton and cytoskeleton, important for muscle function, and mutations in nesprin-1/-2 are linked to muscular dystrophy and heart conditions.
  • Specific nesprin-2 isoforms are found in cardiac muscle, particularly at the sarcomere, indicating a possible role in muscle structure.
  • Nesprin-2 interacts with other proteins, like telethonin, which is affected by mutations linked to heart diseases, suggesting nesprin-2 helps maintain muscle integrity and function.

Introduction: Nuclear envelope spectrin repeat protein (Nesprin) 1 encoded by SYNE1, crucially regulates the morphology and functions of the cell. Mutations in the SYNE1 gene are associated with various diseases; however, their significance in renal cell carcinoma (RCC) remains unknown. In this study, we have investigated the association of SYNE1/Nesprin1 with the progression and prognosis of clear cell RCC (ccRCC).
