Question

A researcher is working to generate a new cancer drug. Thus far, he has identified a compound that can reduce the size of tumors in the lung. However, in order for the drug to work, the lung tumor has to be small. In addition, the tumor cannot have metastasized (spread to other areas of the body). Furthermore, he knows that the drug acts to prohibit the signaling from one tumor cell to another tumor cell. Given the above information, this new drug prohibits:

Answer 1

Answer:

This new drug prohibits the paracrine signaling between the tumor cells.

Explanation:

To this new drug work it will have to stop the tumor cell communication.

That can be done by suppressing the paracrine molecule that is secreted in the extracellular environment and is responsible for the cell-to-cell signaling and further spreading of the tumor cells. If that can be done the small lung tumor can be traded.
