I am excited that you all will have a chance to directly work with an oncologist from the Maine Medical Center Research Institute (MMCRI). Dr. Lucy Liaw has graciously volunteered her time to share her research and data.

In order to understand what Dr. Liaw is researching, you should be able to answer the following questions?
1. What are PC3 cells?
2. How are prostate cancer cells grown in the research laboratory? 3. What is cisplatin? 4. What is shRNA?

Purpose:
Examination of drug resistance in prostate cancer cell lines

Cell lines:
PC3-CTR

PC3-Slug shRNA 2

PC3-Slug sh2 shPTEN 1320

PC3-Slug sh2 shPTEN 3001

Drug:
Cisplatin

Experimental procedure

Drug resistance was tested by using chemotherapeutic drugs including Cisplatin (Sigma, MO)

Cisplatin was dissolved in a minimal volume of DMSO and Adriamycin was

Drug resistance was examined by using colony forming assay.

Briefly, 100,000 cells were seeded in each well of a 6-well cell-culture plate and allowed to grow for 48 hr.

Cells were treated for 24 hr with cisplatin

Cisplatin concentration is ranging from 50, 100, 200 µmol.

After treatment, cells were reseeded at colony forming density (1,000 cells per dish) and allowed to grow for 14–21

days until colonies emerged. Colonies were stained with crystal violet and counted.
