Oncogenesis Flashcards
What are the hallmarks of cancer?
- Self-sufficiency in growth signals
- Insensitivity to anti-growth signals
- Limitless reproduction
- Evading apoptosis
- Tissue invasion and metastasis
Differentiate Oncogenes from Tumor Suppressor genes
Oncogenes: Genes promoting cellular growth
Tumor supressor: Genes inhibiting excessive growth.
Important facts about cancer incidence
- Incidence starts around 30.
2. Palpable cancer means there are a lot of cells
Important facts learned from the models of Human Cancer
- Its the pathway change thats important.
2. Carcinogenesis is a multi-step process
What are the symptoms of CML?
Fatigue, night sweats and high blast counts.
What is the pathogenesis of the Philadelphia Translocation?
BCL is a highly transcribed gene, but when the translocation causes increased ABL expression, it causes an oncogenic mechanism.
How is CML treated?
Gleevec, a tyrosine kinase inhibitor that blocks ABL protein from being phosphorylated.
