Genes that predispose to Cancer Flashcards
name 3 mechanisms for gene mutation
chromosomal translocation, point mutation and viral/bacterial
6 established hallmarks of cancer
evading apoptosis, angiogenisis, evading growth inhibition, autonomous growth signalling, Activating Invasion +
Metastasis, immortality (unlimited replicative potential)
4 emerging hallmarks
avoiding immune destruction, tumour promoting inflammation, genome instability, deregulating cellular energetics
role of p 53?
guardian of genome. invokes apoptosis or DNA repair, also inhibits growth signalling
Philadelphia chromosome is involved in which leukaemia? 2 chromosomes and genes involved
CML. 22;9 Bcr-Abl
Gleevec (imatinib) is a treatment for which leukaemia? what is its MOA
CML. A specific Bcr-Abl tyrosine-kinase inhibitor
does gleevec cure CML?` why/not?
progenitor cell is protected from Gleevec. Therefore Gleevec doesnt cure. Must be taken continuously to remove downstream effect
BH-3 only mimetic ABT-199 is a drug in clinical trial for which disease?
CLL
Main gene involved in CLL? what happens
Bcl-2 - over-expression prevents apoptosis
miRNA(15,16), ZAP -70 and p53 involved with which cancer?
CLL
