Previous studies have shown that selenite, a representative of inorganic form selenium, exerts its anticancer effect by inducing apoptosis in androgen-dependent LNCaP prostate cancer cells, but few studies have determined the nature of cell death induced by selenite in metastatic androgen-refractory PC-3 cells. Our study showed that necrosis-like cell death rather than apoptosis, pyroptosis, or autophagic cell death was caused by selenite in PC-3 cells. Mechanistically, this type of cell death was caused by ATP depletion (26.28 ± 3.39 nmol/mg of control versus 9.12 ± 2.44 nmol/mg of 10 μM selenite treatment) that resulted from phosphofructokinase activity reduction (100.17 ± 0.17% of control versus 21.74 ± 6.65% of 10 μM selenite treatment). Our study also showed that ROS production is necessary for the decrease in cellular ATP levels and in phosphofructokinase activity. To our knowledge, this is the first study showing that selenite can induce necrosis-like cell death in PC-3 cells. Our findings support selenite as an effective compound for the therapy of apoptosis-resistant prostate cancer.

An inhibitory T-lymphocyte receptor that has specificity for CD274 ANTIGEN and PROGRAMMED CELL DEATH 1 LIGAND 2 PROTEIN. Signaling by the receptor limits T cell proliferation and INTERFERON GAMMA synthesis. The receptor also may play an essential role in the regulatory pathway that induces PERIPHERAL TOLERANCE.
A costimulatory B7 antigen that has specificity for the T-CELL receptor PROGRAMMED CELL DEATH 1 RECEPTOR. It is closely-related to CD274 antigen; however, its expression is restricted to DENDRITIC CELLS and activated MACROPHAGES.
The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences CELL DEATH via the process of APOPTOSIS.
A family of calcium/calmodulin-dependent PROETIN-SERINE-THREONINE KINASES. They are ubiquitously expressed in adult and embryonic mammalian tissues, and their functions are tightly related to the early stages of eukaryotic programmed cell death.
A forkhead box transcription factor and transcriptional activator which triggers type 1 programmed cell death (APOPTOSIS) in the absence of APOPTOSIS INHIBITING PROTEINS, including neuronal cell death induced by OXIDATIVE STRESS. It recognizes and binds to the DNA sequence 5'-(AG)TAAA(TC)A-3' and also functions in post-transcriptional regulation of the c-MYC PROTO-ONCOGENE.
