First class Flashcards
What is extracellular matrix (ECM)
Fibrous proteins
glycosaminoglycans
What is Kinase
It phosphorylates a substrate
What gene is Marfan syndrome caused by
Fibrillin I
Common dental symptoms in Marfan
micrognalgia High arched palate Narrow thin face Severe periodontal disease. No apparent local factor TMD
What does BMP do
promotes osteoblast differentiation
Acceleration of bone formation/healing
What is the important of bone
Type I collagen
What is the initial of signal transduction
Growth factors--> Receptors(receptor kinases--> Signaling molecules--> Transcription factor--> Gene regulation/cell response
A transcription factor has to be able to
Come into nucleus
Bind to DNA
Turn something on
For signal transduction whats important
direct binding (protein-protein interaction) Protein modifications such as phosphorylation
What is phosphorylation
The addition of a phosphate
What does Smad 3 use
TGF-beta
What is trigered by signal transduction
Cell proliferation cell cycle cell differentiation Cell movement Cell death- necrosis, apoptosis Cell Clearance- Autophagy
How can you tell if cell is diff
Nucleus is at the bottom
is ciliated
Shape
What is chemotaxis
cellular movement
What is cell death
Necrosis
Apoptosis; Programed, not necessarily associated with inflammation.
