Question

Which of the following proteins promote cellular apoptosis?

Bcl-2

Bax

Bcl-xL

beta-actin

Question 2

Which change in PARP indicates activation?

methylation

phosphorylation

cleavage

nitration

Question 3

Which signaling pathway is activated by Ras in malignant leisions?

MAPK signaling

Nf-kB signaling

PIK3 signaling

Akt signaling

Question 4

Phosphorylation of and P65 result in what fate for Nf-kB?

degradation in the proteasome

nuclear export

translocation into the nucleus

cleavage and activation

Question 5

What is the importance of Kras in PDAC development?

It activates NF-kB signalling and Akt signaling

It inhibits caspase cleavage and apoptosis

It promotes phosphorylation of P65

It promotes PARP phosphorylation

Bcl-2

Bax

Bcl-xL

beta-actin

Explanation / Answer

Q 1). b. Bax

Apoptosis is the programmed cell death. Bcl-2 is anti-apoptotic, Bax- pro apoptotic, Bcl-xL - anti-apoptotic, beta-actin - one of the isoforms of actin.

Q 2). b. phosphorylation

Phosphorylation of PARP (poly ADP-ribose polymerase) activates it.
