# Narration and storyboard draft: Nuclear Lamina as Global Regulator

Authored draft, approximately 60–90 seconds; no rendered video claimed.

The nuclear lamina is more than a mechanical shell, but peripheral contact is not a universal gene-off switch. Genome maps show that lamina-associated domains tend to have low expression. Causal tests reveal a more varied picture. Lamin-null stem cells can retain gene repression and differentiation, while other cell states show real changes in genome organization and transcription. In one local system, the enzyme needed for silencing differed from the enzyme needed to keep the locus at the edge. A recent study identified LBR and LAP2 as redundant anchors: major early detachment changed relatively few genes, whereas prolonged loss produced much broader effects. Consensus also helped locate a new B-lamin study linking speckle proximity and RNA, but the same cells had increased apoptosis and reduced proliferation. Those controls matter. Our global-claim rating is Gamma; context-specific architecture regulation scores Epsilon. The next decisive test should separate a lamin-silencer interaction from mechanics and use native genes, matched rescue, timing and cell-state controls.

1. Show the exact claim, grade and confidence.
2. Show selected publication milestones; label experimental systems and clinical endpoints.
3. Contrast the strongest result with its source-specific limitation.
4. End with the boundary experiment and primary-source links.
