What are the two hallmark characteristics that determine if a cell is a stem cell or not? Capacity for: - Self renewal - Give rise to differentiated cells What does knowledge of stem cells entail? Helps: - with information about developmental biology - understand adult tissue homeostasis - understand disease biology - * immense potential to serve as therapeutic agents What is an example of an approved SC treatment in Canada? Prochymal: Mesenchymal stem cells indicated for graft vs ...

What are the 5 well-known enzyme-linked cell surface receptors? - Answer 1. Receptor Guanylyl Cyclase: produces cGMP 2. RTK: phosphorylate tyrosine residues leading to association of signalling molecules and cascade 3. TK Associated Receptors: associate with proteins having TK activity 4. Receptor Tyrosine Phosphates: Removes phosphate on tyrosine residues 5. Receptor Serine/Threonine Kinases: phosphorylate specific Serine/Threonine residues on IC signalling molecules How are RTK and T...

CPPS 325 FINAL EXAM QUESTIONS WITH COMPLETE SOLUTIONS RTK vs. Serine/Threonine Phosphorylation ? - Answer-Tyrosine phosphorylation is rare (1%) relative to serine/threonine residue phosphorylation. Tyrosine phosphorylation is the major mechanism of receptor signal transduction. What is the net effect of activated TKs? - Answer-Tyrosine phosphorylation on target proteins. What do TK pathways mediate? - Answer-Cell growth (growth factors), differentiation, host defense, metabolic regulati...

CPPS 325 FINAL EXAM QUESTIONS WITH COMPLETE SOLUTIONS What is src? - Answer-Src is a non-receptor TK, so it does not span a membrane. It is a tyrosine kinase. And although it is cytoplasmic TK it can still bind to activated RTKs. What is contact inhibition confluency? - Answer-Stops Src domains signalling and therefore cells stop dividing. If there is an issue then cancer can result and mutation causes an inhibition of the stop signal so the cells keep growing and dividing. What are...
