1.11.1.12	phospholipid-hydroperoxide glutathione peroxidase	breast invasive ductal carcinoma cell	PHGPx expression levels are downregulated in poorly differentiated (grade 3) breast invasive ductal carcinoma. PHGPx expression levels decrease gradually with tumor grade from grade 1 to grade 3. Downregulation of PHGPx in cases that showed p53 accumulation compared with cases without p53 immunostaining is observed. PHGPx is downregulated in cases without progesterone receptors immunostaining compared with cases with PR immunostaining	686896
