Hi Answer:
Q. 1. Which of the following would be considered stromal cells (Choose all that apply):
Answer: Option A & D [Macrophages in adipose tissue and Connective tissue cells surrounding muscle tissue]
The stromal cells are the connective tissue cells of any organ. These cells support the function of parenchymal cells of that organ. In addition to this stromal cells play an active role in inflammation responses and also controlling the amount of cells accumulating at an inflamed region of tissue.
Q. 2. Is cell growth/proliferation promoted or inhibited when these events occur:
Answer:
AMPK is inactivated: Promotes the cell growth/proliferation
Rheb is in its GTP-bund state: Promotes the cell growth/proliferation
Akt phosphorylates in the TSC complex: Inhibit the cell growth/proliferation
P53 drives the expression of p21: Inhibit the cell growth/proliferation
pRB gets phosphorylated: Promotes the cell growth/proliferation
Adenylate kinase generate AMP: Promotes the cell growth/proliferation
Enhanced insulin/IGF1 signalling: Promotes the cell growth/proliferation Telomerase attrition: Inhibit the cell growth/proliferation
