The effect observed by a cell when treated with only growth hormone and when the cells are treated with both epinephrine and growth factor. Introduction: A cell is the smallest unit which helps in the manufacturing of the structure of an organism. Cells divide by means of the cell cycle. There are a number of hormones and enzymes involved in the process of cellular multiplication. The rate of cell division is altered by the use of hormones.

A growth factor Fsh3 stimulates the proliferation of culture fish cells. The receptor that binds Fsh3 is a receptor tyrosine kinase (RTK) and there are numerous fish tumor cell lines that have a mutation for the gen for this receptor. Which of the following mutations would be expected to promote uncontrolled cell proliferation. a mutation that inactivates the protein tyrosine phosphatase that acts on the receptor a mutation that prevents the binding of the normal extracellular signal to the receptor a mutation that inhibits the Ras GEF a mutation that destroys the kinase activity of the receptor a mutation that prevents dimerization of the receptor

Cell lines divide normally in a defined medium containing growth factors, but fail to divide in the absence AGF (a growth factor). However, a mutant cell line continues to divide even in the absence of AGF. Elevated levels of Rb phosphorylation and the effects of receptor and Mek inhibitors suggest a mutation activating an oncogene. Inhibitors of Mek inhibit cell division of the mutant cell line, but inhibitors to the ADGF receptor, a receptor tyrosine kinase (RTK) with homology to EGFR, do not. Outline the RTK pathway leading to the phosphorylation of Rb to form p-Rb.

Metabolic syndrome is a clustering of various conditions including high blood pressure, high blood sugar, excess body fat, high serum triglycerides, and low high-density lipoproteins. Scientists studying metabolic syndrome cultured fibroblast cells from a metabolic syndrome patient and a healthy volunteer and challenged the cells to 100 nM insulin. Ten minutes after the stimulus was applied, they used a protein immunoblot to measure the amount of phosphorylated insulin receptor in the cultures. Use the passage to answer the question. Some patients with metabolic syndrome can continue to gain weight even if they consume fewer calories than other human adults. Based on this finding, which conclusion is MOST likely true? A. Patients with metabolic syndrome do not eliminate as many calories during excretion. B. Patients with metabolic syndrome do not expend as much energy during muscle contractions. C. Patients with metabolic syndrome have more efficient…
