PC3 or PC-3 is a human prostate cancer cell line used in prostate cancer research and drug development. PC3 cells are useful in investigating biochemical changes in advanced prostate cancer cells and in assessing their response to chemotherapeutic agents. PC3 cells are also used to study viral infection in mammalian cells that exhibit an immune response.

PC3 cells are also used to study viral infection in mammalian cells that exhibit an immune response. ==History== The PC3 cell line was established in 19791 from lumbar vertebral metastasis of grade IV prostatic adenocarcinoma in a 62-year-old Caucasian male. ==Responses and behaviours== These cells do not respond to androgens, glucocorticoids or fibroblast growth factors, but results suggest that the cells are influenced by epidermal growth factors. PC3 cells have high metastatic potential Comparisons of the protein expression of PC3, LNCaP, and other cells have shown that PC3 is characteristic of small cell neuroendocrine carcinoma. PC3 cells have low testosterone-5-alpha reductase and acidic phosphatase activity, and do not express PSA (prostate-specific antigen). ==Characteristics== Karyotypic analysis: near-triploid, having 62 chromosomes. Expression of CK7, CK8, CK18, and CK19, non AR and PSA. From a morphological point of view, electron microscopy revealed that PC3 cells show characteristics of a poorly-differentiated adenocarcinoma. Tumor size approximately 100 % increase: approximately 33 h. They have features common to neoplastic cells of epithelial origins, such as numerous microvilli, junctional complexes, abnormal nuclei and nucleoli, abnormal mitochondria, annulate lamellae, and lipoidal bodies. Q-band analysis showed no Y chromosome. ==Applications in science== PC3 cells can be used to create subcutaneous tumor xenografts in mice to investigate the tumor environment and therapeutic drug functionality. ===in vitro study=== Treatment by quercetin induced various tumor suppressor genes including transforming growth factor β receptor 11, and quenched reactive oxygen species.
