Foundations Flashcards
amino acids modified in Golgi apparatus
serine, threonine, asparagine
nuclear localization signals
proline, arginine, lysine
G1–>S
Cyclin D-CDK4
Cyclin E-CDK2
G2–>M2
Cyclin A-CDK2
Cyclin B-CDK1
target lysosomal protein
mannos-6-phosphate
important for phospholipids found in myelin and sythesized in peroxisomes
plasmalogen
mechanism of cell injury
ATP depletion, mitochondrial damage, influx of calcium, accumulation of oxygen-derived free radicals
irreversible cell injury
calcium influx, damage to plasma membrane, rupture of lysosome, mitochondrial permeability, pyknosis, karyolysis, karyorrhexis
acute inflammation (neutrophils)
IL-1, IL-6, TNF-alpha
netrophil extravasation
rolling, tight binding, diapedesis, migration
neutrophil chemotaxis
IL-8, LTB4, C5a, kallikrein
types of collagen mnemonic
“strong, slippery, stretchy, BM”
type 1 collagen
strong: bone, skin, dentin, scar tissue
type II collagen
slippery: cartilage, vitreous body, nucleus pulposus
type III collagen
stretchy: blood vessels, skin, uterus, fetal tissue, granulation tissue, reticular fibers
