| Comments： | PTEN mutations are one of the the most frequent genetic alterations found in human prostate cancers. This cell line, PTEN-CaP8, along with its isogenic partner, PTEN-P8 were generated to better understand the underlying molecular mechanisms of PTEN in prostate cancer progression and control, as well as the signaling pathways controlled by PTEN. PTEN-CaP8 is homozygous for Pten deletion. This cell line was generated from tissue that had not been subjected to hormone ablation therapy and are thus ideal for the study of human refractory prostate cancer formation, as many of the most well-studied human prostate cancer cell lines are from late-stage cancer tissue that has undergone such therapy. PTEN-CaP8 cells have lost the second Pten loxp allele and PTEN function as shown by the loss of PTEN protein expression and increased P-AKT levels. Pten null cells are tumorigenic in both male and female severe combined immunodeficiency mice despite no prior exposure to hormone ablation therapy. Complete loss of PTEN causes decreased p27 and E-cadherin expression. |
| Complete Growth Medium： | The base medium for this cell line is Dulbecco’s Modified Eagle’s Medium (ATCC® 30-2002™). To make the complete growth medium, add the following components to 500 ml of the base medium: Fetal bovine serum (FBS; ATCC® 30-2020™) to a final concentration of 10% |
| Subculturing： | Subculture when culture reaches ~70-85% confluence. A subcultivation ratio of 1:20 to 1:50 is recommended.
|
