Question

what's the right answer?

Question 4 1 pts USE THIS INFORMATION FOR ALL QUESTIONS: Many forms of cancer are influenced by hormones and growth factors. Some breast cancers are "HR-positive" or "HR-negative" and "HER2-positive" or "HER2-negative," meaning that the tumor cells have or lack hormone receptors (HR) for estrogen and/or progesterone, and they have or lack receptors (called HER2) for human epidermal growth factor 2 (hEGF-2). Pigray only works on these cancers when the cancer cells have a mutation in the gene for the phosphatidylinositol 3-kinase enzyme (PIK3). Mutated PIK3 enzymes are overactive. Piqray is a PIK3 inhibitor. What happens in Piqray-treated cancer cells? Pigray digests PIK3 enzymes. PIK3 activity increases more than in untreated cells. Pigray slows the phosphorylation of phosphatidylinositol Pigray repairs PIK3 genes. Next →

Answer 1

Piqray slows the phosphorylation of phosphatidylinositol

Piqray is an inhibitor of phosphatidylinositol 3 kinase (PIK3). The inhibition of PIK3 by Piqray leads to increase in estrogen receptor transcription in bresat cancer cells.
