Question 15

VHL gene mutation

Answer 15

Von hippel lindau

Question 16

VHL gene mutation disrupt the ——- —- complex

Answer 16

Ubiquitine ligase complex

Question 17

HIF -1 alpha is what? Related to what disease.

Answer 17

Hypoxia indicting factor alpha. Related to VHL disease.

Question 18

Effects of HIF-1 alpha

Answer 18

Induces PDFg, VEGF, EPO and TGF alpha . Which bring about more vessels, so more blood, so more oxygen to respond t hypoxia situations.

Question 19

When is HIF 1 alpha abnormally expressed in large amounts as though person we’re in hypoxia situation?

Answer 19

VHL

Question 20

Hemangioblastoma, Rena cell carcinoma, and pheochromocytoma

Answer 20

VHL

Question 21

vWF gene is in chromosome —-

Answer 21

Chromosome 12

Question 22

What is platelet adhesion? What does it INVOLVE (ingredients, if you will)?

Answer 22

Exposure of collagen, receptors of collagen bind to vWF, then vWF bind tosurfwce receptor on platelet called gp1b

Question 23

What are the ingredients of platelet aggregation?

Answer 23

Platelet changes conformation and expresses on its surface: ADP and TXA2.
Then receptor gp2b3a is expressed and binds fibrinogen, which binds another platelet’s gp2b3a.

Question 24

What drug prevents adhesion of platelets

Answer 24

Clopidogrel

Question 25

What drugs prevent platelet aggregation?

Answer 25

Abciximab, agrostat

Question 26

Early clotting is done by —— or white clots

Answer 26

Platelet clots

Question 27

Late clotting is done by red or —- clots

Answer 27

Fibrin clots

Question 28

Types of vWF:
Type 1, what happens with vWF?
Type 2a?
Type 2b
Type 3?

Answer 28

Type 1- quantitative, very little vWF (most cases)
Type 2a— quantity is normal but quality no, the ones that are present cannot function well
Type 2b - the ones present function too well, they hyper bind to collagen so they get out of circulation, so very little available vWF and little platelets
Type 3 - complete absence of vWf
