Study Notes
Cell Cycle and Cancer
- Cancer cells primarily show defects in the G1 phase of the cell cycle.
Genetic Alterations and Cancer
- Genetic alterations driving the progressive transformation of cancer cells are primarily mutations in tumor suppressor genes and oncogenes.
Cellular Proliferation
- The process that marks the end of a cell's proliferation due to reaching the limit of divisions is senescence.
Angiogenesis in Cancer
- The main purpose of angiogenesis in cancer is to supply tumors with oxygen and nutrients.
Metastasis
- Metastasis is the process that involves the spread of cancer cells to secondary organs.
Cancer Drug Targets
- Approximately 78% of cancer drugs target crucial drivers of cancer.
Cell Cycle Checkpoints
- The main function of cell cycle checkpoints in cancer is to detect and respond to DNA damage.
Cancer Drug Targets
- Cancer drugs target cancer cells, specifically proliferating cells.
DNA Replication Inhibitors
- An example of a drug targeting DNA replication is Gemcitabine.
Immunotherapy
- Immunotherapy is a type of cancer treatment that involves harnessing the patient's immune system to target their own cancer.
Tumor Heterogeneity
- Tumor heterogeneity describes the combination of genetic, non-genetic, and tumor microenvironment factors.
Engineered Immune Cells
- Chimeric Antigen Receptor (CAR) T-cells are an example of engineered immune cells used as cancer drugs.
