Diabetes Flashcards
What happens to the incretic effect in T2D?
Reduced
GLP-1 analogs are contraindicated w/ family hx of what 3 disorders?
- TMC (Thyriod microcarcinoma)
- Pancreatitis
- Renal failure
Stable microtubules moved by dynein
Cilia and Flagella
Strong regulator of actin organization
Rho family GTPase
secreted from ileum and colon, incretin, decrease, gastric emptying, glucogon decrease, improved cardiovascular risks
GLP-1
Incretin effect
GI peptides that increase insulin senstivity
In type 1D, Hypoglycemia-associated autonomic failure, increase in cortisol is induced by?
When glucagon response is lost, and epinephrine signaling is desensitized
Why is adherence important?
Extend quality of life,
Avoid complication (neuropathy, vision problems, organ failures),
Cost of non-adherence is high
Factors of nonadherence:
Patient family characteristics (SES and family composition Knowledge patient/family adjustment and coping), Disease related characteristics, Healthcare providers/ system
GLP-1 analagoues
Exanatide, Liraglutide
How is GLP-1 analogues given?
Subcutaneous
Interventions to improve adherence
Educational,
Organisational
Behavioural
cAMP increases due to signaling molecules
Glucagon and epinephrine
PFK-1 Is inhibited by
ATP and citrate
PFK-1 is activated by
AMP, fructose 2,6 Bis-P
How is glycogen synthase inactivated? and glycogen phosphorylase activated
Phosphorylation from Protein Kinase A (G-protein signaling pathway, activated by cAMP)
What does Protein Kinase A activate
Glycogen phosphorylase and synthase in liver, and R-domain in CFTR
How is glycogen used?
phosphorylated to Glucose-1-phosphate
What does glucagon do in gene expression levels?
Glucagon induced expression of phosphoenolpyruvate carboxykinase
eg. of compartmentation of metabolic activities
transport fatty acid to mitochondria for beta oxidation and synthesis takes place in cytoplasm
Secondary messengars of catecholamines
cAMP and Calcium
How is catecholamines secreted
sympathetic nervous system–> adrenal gland–> catecholamines–> secondary messengers—-> acute response
Example of catecholamines
epinephrine and norepinephrine
Effect of catecholamines
Lungs: more oxygen,
Adipose: Free fatty acid,
Liver: Glycogen breakdown,
muscle : ATP production for movement from Free FA and glucose
