Mouse Models of Prostate Cancer

Prostate Cancer
• Prostate Cancer: disease marked by
abnormal growth of tumor cells in the
prostate gland
• Prostate Cancer is detected by
– Digital Rectal Exam
– Biopsy
– PSA serum reading
PSA Serum Screen
• PSA is a biomarker for CaP
• Our Question: Does PSA play a role in
CaP?
-Mouse studies
PSA mouse study
• Mice don’t have PSA
• We already put WT PSA gene into mice
• We now need a mutant form of PSA gene to
put in mice so that we can compare whether
the mut mouse will develop CaP in a
different way than the WT PSA mouse
Project Goal
• Mutate the PSA gene (in a plasmid) nucleotide
sequence so that a Serine amino acid is changed to
an Alanine in the PSA protein (gene product)
• Prepare the mutated PSA gene for injection into
the mouse
