Webb11 apr. 2024 · We show that nucleolin is phosphorylated downstream of RAS, which increases its binding to pre-ribosomal RNA (rRNA), boosts rRNA production, and promotes ribosome biogenesis. This nucleolin-dependent enhancement of ribosome biogenesis is crucial for RAS-induced pancreatic cancer cell proliferation and can be targeted … WebbThe proof shown in the video only works for the internal angles of triangles. With any other shape, you can get much higher values. Take a square for example. Squares have 4 angles of 90 degrees. That's 360 degrees - definitely more than 180. A regular pentagon (5-sided polygon) has 5 angles of 108 degrees each, for a grand total of 540 degrees.
