Physical activity guidelines
150min/week moderate-intensity

Phytochemicals
Natural compounds in plants that have biological activity
p53
Cell repair, division
Li Fraumeni syndrome
RB-1 mutation
Retinoblastoma
E2F etc etc
APC
Familial adenomatous polyposis
APC targets B-cetenin for degradation
B-catenin = cell proliferation
BRCA1/2
Breast cancer
Repairs double stranded breaks, cell division, cell death
WT1/2
Cell division, transcriptional regulation
NF1 mutation
Neurofibromatosis
GAP that slows RAS pathway
PTCH mutation
PTCH inhibits SMO (pro proliferation genes)
No PTCH function = SMO function = constitutive cell proliferation
Methotrexate
Inhibits Dihydrofolate Reductase
DHF –> THF
5-Fluorouracil
Inhibits Thymidylate synthase
Azaserine
Inhibits Nitrogen transer from glutamine
Hereditary Orotic aciduria
Defect in UMP synthase
Retarded growth, hypochromin anemia, excretion of orotic acid
Treatment with uridine/uracil
N-acetylglutamate synthase defect
Cannot make N-acetyl glutamate
Cannot activate CPS-I
Elevated ammonia, early death
CPS-I defect
Cannot make carbamoyl phosphate
Elevated ammonia in blood and urine
