โ€ฆand it provides a better understanding of the normal function of lamins, particular in skeletal and cardiac muscle cells. The work was led by the amazing Jacob Odell and supported by the National Institutes of Health (NIH), National Science Foundation (NSF), and Leducq Foundation.

This effect is due to the unique rod domain of lamin A/C, and does not require the lamin Ig-fold or tail, nor unique binding partners. This work has direct implications for our understanding of how mutations in the LMNA gene cause muscular dystrophy and heart diseaseโ€ฆ

What allows lamins A and C to confer much stronger mechanical stability to the nuclei than lamin B? We show that even though all lamins can protect the nucleus from small cell intrinsic forces, only lamin A/C protect the nucleus from large deformations: www.biorxiv.org/content/10.1...

The entire nation should protesting this utterly unwarranted, unprecedented, & probably illegal on-going attack on a university. It's right out of the authoritarian playbook. It's an assault on possibility free speech, free thought, & dissent.
Fascism is coming small step by small step, not at once.

If biotech wants to continue to recruit highly talented, energetic, and creative PhDs they need to help us to advocate for stable funding for young scientists in academia to prevent a brain drain and loss of scientific innovation.

Cartoon showing key mechanotransduction signalling pathways to the nucleus. Mechanosensitive ion channels at the plasma and nuclear membranes allow Ca2+ entry into the cytoplasm and nucleus, activating downstream signalling pathways. NE stretching opens NPCs, facilitating entry of transcription factors (TF) and transcriptional coregulators (TCR) that alter gene expression. Additionally, NE stretching activates Ca2+ channels in the ER, promoting Ca2+ entry into the nucleus. Stretch-induced activation of cytosolic phospholipase A2 (cPLA2) further drives the arachidonic acid (AA) pathway, leading to gene expression changes.

Second, women make terrific leaders. They tend to be organized and prepared. They also tend to be more empathic as they have often experienced more challenges and setbacks than men in similar positions. They tend to be more courageous, particularly when the stakes are high.

Direct Economic Contributions NIH directly supports the economy through investments in research institutions and job formation.

Executive wants to frame the NIH indirects cut as $4B in savings.

But given that NIH returns $2.5 on every $1 investment, this would actually cost US economy a net $6 BILLION (per year!). Not to mention the human costs of wrecking education and research sectors and the communities they serve.
