Answer #1

The correct answer is True. Aspartate Rescues the cell from S-phase Arrest Caused by Suppression of Glutamine deprivation in KRas-driven Cancer Cells. The S- phase arrest occurs due to the deficiency of nucleotides for the DNA synthesis. Hence the cell is unable to synthesise DNA in S phase. Aspartate is the metabolite for purine and pyrimidine nucleotides. Thus aspartate helps in the synthesis of the nucleotides that in return help in the DNA synthesis and rescue the cell from S phase arrest.

Thank you. Please do provide with a Thumbs up.

Metabolic reprogramming in KRas-driven cancer cells involves glutaminolysis whereby glutamine is deamidated by glutaminase to glutamate, which is then deaminated by glutamate dehydrogenase to a-ketoglutarate and NH4+.  a-ketoglutarate can then continue through the TCA cycle to citrate and exit the mitochondria where acetyl-CoA is regenerated for fatty acid synthesis.
