Inhibition of the apoptosis : Apoptosis is programmed cell death which helps to remove the aged as well as damaged cells out of the body. Cancer cells are damaged cell and that should be removed from the body but unfortunately due to the inhibition of apoptosis the number of cacerous cells increases in the body. Unlike mutagens it act on the 3’ UTR region of the cell’s DNA.
Effect of mutagens : Mutagens cause the change in the DNA converting proto oncogenes to oncogens. This cancer causing genes make the proliferation of cancer cells unconditionally. Mutagens such as chemical agents, radiation such as ionic and non-ionic etc. Mutagens act on promoter and that is a major difference from then inhibitors of apoptosis.

All the meachanisms are similar because they allow to cancer cell metastasis as well as uncontrolled growth and proliferation.

Hope it will helpful to you. Thank you

All the best

Describe the common features shared by GPCRs and RTKs in their signaling mechanisms, focusing on how they are able to amplify signals. Specifically, how is the signal from one binding event (i.e., the binding of one ligand molecule to an individual receptor) propagated and strengthened? Describe one difference in how GPCRs and RTKs transform extracellular signals into intracellular responses.

Question 1: You have been studying various oncogenes and tumor suppressor genes in tumor cell lines in vitro, but would now like to address certain questions in mouse models in vivo. For each of the questions below, briefly describe the type of mouse model you would use. For xenograft/allograft experiments, briefly describe the type of cell lines you might use and the experimental end points you would be looking at. For GEMs, briefly describe the type of mouse you would...

Describe the various mechanisms for avoiding and controlling congestion employed by TCP, namely: slow start, congestion avoidance phase and reaction to congestion. Further, assume that a TCP connection at steady state with AIMD parameters alpha = 1 Byte and beta = 0.5 is currently sending 107B of data (i.e., congestion_window = 107B). Assuming no congestion drops occur in the next three rounds of transmission, what is the congestion-window in the next three rounds? If there is a congestion drop after...
