| Title |
Profiling of altered gene expression induced by 1 hr of zinc in human prostate cancer cells |
| Sample type |
RNA |
| |
|
| Source name |
PC-3 cell line
|
| Organism |
Homo sapiens |
| Characteristics |
Androgen-independent prostate carcinoma (PC-3) cell line
|
| Biomaterial provider |
ATCC, Rockville, MD, USA
|
| Treatment protocol |
PC-3 cells at 70-80% confluence in T-75 flasks (Corning, Corning, NY) which were synchronized by 24 hrs hormone-depletion. Serum-free media were refreshed following starving process and zinc (1,500 ng /mL) was introduced for 1 hr. Both media and Cells were collected concurrently. Cell pellets were immediately frozen and stored at -80 oC pending for RNA isolation.
|
| Growth protocol |
Cells were maintained in RPMI 1640 medium (GIBCO BRL) with 5% fetal bovine serum (10% for LNCaP and PC-3) plus 1U/ mL penicillin-streptomycin in a 5% CO2 atmosphere at 37oC
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted with the Qiagen (Valencia, CA) RNeasy Mini kit according to the manufacturer?s protocol.

| Description |
Zinc effect on gene expression of HPR-1 cells was evaluated using Applied Biosystems (Foster City, CA) human genomewise microarray chips V2.0. For each chip, 2 microgram total RNA from each sample was used for converting to cRNA. The synthesis of cRNA and a subsequent hybridization were completed by the Core Facility at UMBI (University of Maryland Biotechnology Institute, Baltimore, MD) according to the ABI standard protocol.
