Study Notes
Carcinogens and Cancer Cells
- Carcinogens include substances like UV light, cigarette smoke, fat, and testosterone; all of these are linked to cancer.
- Fat is specifically identified as a carcinogen promoting colon cancer.
- Cancer cells differ from normal cells as they continue to divide even when densely packed.
Cell Division and Specialized Cells
- Neurons and specialized cells divide infrequently because they enter the G0 phase of the cell cycle, indicating a quiescent state.
- Cell lines that do not exhibit density-dependent inhibition or anchorage dependence show characteristics of tumors.
Chemotherapy and Cancer Treatment
- Effective chemotherapeutic drugs target rapidly dividing cells to combat cancer.
- All cancers share a commonality in that they have escaped normal cell cycle controls.
Tumor Induction and Cancer Management
- Tumors in mice were previously implanted under the skin for cancer studies.
- In treating advanced prostate cancer, standard protocol involves chemical castration.
Hormonal Influence and Cancer Resistance
- High levels of dihydrotestosterone in prostate cancer patients suggest that their condition has become resistant to standard treatments.
- Prostate cancer cells possess the ability to both activate and inactivate specific genes.
Monitoring and Genetic Risks
- Improvement in prostate cancer is indicated by a decreasing PSA (Prostate-Specific Antigen) level.
- All individuals carry the BRCA gene, including men, but only certain mutated versions of this gene increase the risk of aggressive breast and ovarian cancers.
- Genetic tests do not confirm the presence of the BRCA gene but can identify the version of the BRCA gene present. The normal BRCA gene does not cause breast cancer.
