Question

Anatomy & Physiology question HELP

Wingless-type genes and the proteins they manufacture help body tissues repair more quickly. Mice with increased wingless-type proteins were able to repair bone tissue 3.5 times faster after a fracture than normal mice. The wingless-type protein was originally discovered in cancerous cells. What is one bioethical concern with testing this protein on humans?

A.) What works in mice may not work in humans.
B.) Wingless-type proteins may increase the risk of cancer.
C.) Wingless-type proteins can cause damage to tissues
D.) This treatment could eliminate stem cells.

so far I've eliminated D as an answer choice.

Answer 1

It's easy, it's B - wingless-type proteins may increase the risk of cancer.

Dangerous to experiment like that unless extended trials in rats have been done to eliminate unknowns in terms of cancer-risk assessment (that is, uncontrolled proliferation of cells)

Answer 2

@kassem23 why can't it be A or C?

Answer 3

@kassem23 hello

Answer 4

@aaronq can you help? please

Answer 5

What do you think it is?

Answer 6

I think its A, B or C. leaning more towards A, but @kassem23 is trying to say its B so I don't know

Answer 7

I would go with A but ask @aaronq

Answer 8

"Mice with increased wingless-type proteins were able to repair bone tissue 3.5 times faster after a fracture than normal mice. The wingless-type protein was originally discovered in cancerous cells"

Read and consider this.

Answer 9

"The wingless-type protein was originally discovered in cancerous cells""

What does that suggest? It suggests that this protein MIGHT be involved in the proliferation of cells (due to mutagenic effects) causing cancer.

Answer 10

Thus, we can conclude that it's unsafe to treat human beings with this protein given its ASSOCIATION with cancer.

Answer 11

Also, don't give out answers. @kassem23

Answer 12

Looking at it another way -- what does it mean to increase the proliferation of bone cells 4.5 times? It's increasing the number of cells. What is cancer? It's the UNCONTROLLED proliferation of cells.

Thus, given that they found this protein IN cancerous cells, it's very likely that it can CAUSE cancer, since the proliferation goes haywire, and it becomes uncontrolled.

Do you understand now?

Answer 13

Kassem has the right answer, the keywords in the question you need to address are "bioethical concern".

Answer 14

all the answers they provided are true, but you need to look for what the question is asking

Answer 15

okay i get it now, thanks guys
