Title |
Profiling of altered gene expression induced by 6 hrs of zinc in human prostate cells |
Sample type |
RNA |
|
|
Source name |
HPR-1
|
Organism |
Homo sapiens |
Characteristics |
Human prostatic cell line derived from normal prostate epithelial tissue (HPR-1)
|
Biomaterial provider |
Dr. C.K. Choo, University of Hong Kong, China
|
Treatment protocol |
Zinc effect was initiated with cells at 70-80% confluence in T-75 flasks (Corning, Corning, NY) which were synchronized by 24 hrs hormone-depletion before the introduction of zinc treatments. Hormone-free media were refreshed following starving process and zinc (1,500 ng /mL) was introduced for 6 hrs. Both media and Cells were collected concurrently. Pellets were immediately frozen and stored at -80 oC pending for RNA isolation.
|
Growth protocol |
Cells were maintained and propagated in Keratinocyte-SFM supplemented with 1U/mL penicillin and streptomycin sulfate, EGF 0.005 mg/mL, and bovine pituitary extract 0.05 mg/mL 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.
