Cell birth and death III Flashcards
what is important during development?
apoptosis
what happens in polycystic disease?
too much apoptosis
what happens to chromatin during apoptosis?
it gets disorganized
dna ladder
characteristic of apoptosis
basic process of apoptosis (3)
induction
modulation
execution
induction
physiologic, damage related, therapy associated
2 major pathways induction
intrinsic and extrinsic
Modulation
Bcl proteins
intrinsic pathway only
Modulation
execution
caspases followed by endonucleases
directly responsible for blebbing
caspases
caspases
cytoskeletal cleaving, and activate endonuclease
inducers of apoptosis (3)
- physiological activators
- damage-related activators
- therapy associated
endonucleases are responsible for what we see in the
DNA ladder
can be both pro- and anti- apoptotic
