Rest Flashcards
Olaparib
Inhibits PARP1 > double strand break >when tumors don’t have HR > apoptosis
Only ovarian cancer
POLE/MMR deficient tumors
Better prognosis
Lots of T-cell infiltration
MMR proficient tumors
Worse prognosis
MSI
Caused by MMR deficiency
Associated with colon and gastric cancer
EMT
Loss of E-cadherin
Gain of N-cadherin
CHEK2 mutation
BRC
1100delC
NTHL1 mutation
ademenatous polyposis, CRC
HIF-1alpha
Oxgen sensing, stimulation of angiogenesis
KRAS mutational tumors
Not sensitive to EGF-inhibitors
5-FU
MMR proficient tumors
PD1
Expressed by activated T-cells
When bound to PDL1 inhibits T cell activity
Anti-PD1 therapy
Best for tumors with lots of mutations
Double minutes
Small fragments of extrachromosomal DNA
Chromothripsis>gene amplification>double minutes
Chromothripsis
Thousands of chromosomal rearrangements
