What signals the cell to die in response to factors like UV and cytotoxic T-cells?
Cell death signals
How are signals transmitted to the nucleus for cell division?
Via signal transduction and mitogenic signalling pathways
What maintains the balance in cell proliferation and inhibition in tissues?
External stimuli and normal tissue restoration
What characterises receptor tyrosine kinases (RTKs) and their activation?
Cytoplasmic tyrosine kinase domain phosphorylates peptides when ligands bind
What happens when a cell receives a mitogenic signal?
Activated protein translation and pathways for energy production, anabolic metabolism, and creation of organelles
How does oncogenic activation of p21 RAS influence cell proliferation?
Stimulates excessive proliferation by amplifying signals
