Which protein's overexpression is associated with GM6112 cells becoming cancerous?

• A. cFLIP
• B. Caspase-8
• C. FADD
• D. Fas

Answer: (A)

The correct choice indicates that the overexpression of cFLIP is associated with GM6112 cells becoming cancerous. cFLIP, or cellular FADD-like IL-1β-converting enzyme-inhibitory protein, is known to inhibit apoptosis by interfering with the activation of caspases, particularly caspase-8. When cFLIP is overexpressed, it prevents the normal apoptotic process from being initiated in response to cellular stress or damage, which can lead to uncontrolled cell proliferation and tumorigenesis. In normal physiological conditions, caspase-8 plays a crucial role in the apoptotic pathway mediated by death receptors, which, when activated, lead to programmed cell death and thus help eliminate damaged or potentially harmful cells. Overexpression of cFLIP results in decreased caspase-8 activity, allowing cells to evade apoptosis and contribute to cancer development. FADD (Fas-associated protein with death domain) and Fas (a member of the TNF receptor family involved in apoptosis) are also related to the apoptotic pathways. However, their roles are typically more related to promoting apoptosis rather than inhibiting it. Therefore, in the context of GM6112 cells becoming cancerous, the overexpression of cFLIP specifically
