Key Concepts in Cancer prevention
Car t-cells (chimeric antigen receptor t-cells)
CAR T-cells are a type of immunotherapy where a patient's own T-cells are genetically modified in a lab to express artificial receptors (Chimeric Antigen Receptors) on their surface. These engineered T-cells are then reinfused into the patient to specifically identify, search, and destroy cancer cells that express a particular antigen, offering a highly targeted treatment approach.
Crispr-cas9
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary gene-editing technology derived from a bacterial immune system. It uses a Cas9 protein (the 'scissor') guided by an RNA molecule to make precise cuts in specific DNA sequences. This allows scientists to remove, insert, or modify genes with high accuracy, enabling the reprogramming of cells for therapeutic purposes.
Immunotherapy / checkpoint inhibitors
Immunotherapy is a category of cancer treatment that boosts or restores the immune system's ability to fight cancer. Checkpoint inhibitors are a specific type of immunotherapy that block proteins (like PD1 or CTLA4) that act as 'brakes' on T-cells. By taking these brakes off, T-cells can become more active and effective at targeting and eliminating cancer cells.
Innate vs. adaptive immune system
The immune system is divided into two main components: the innate immune system, which provides a rapid, non-specific 'first alarm' response using cells like dendritic cells and macrophages, and the adaptive immune system, which offers a highly specific, long-lasting response through lymphocytes (B cells and T cells) that learn to recognize and target specific pathogens.
Mutagens & carcinogens
Mutagens are agents (like chemicals, radiation, or viruses) that cause changes (mutations) in the DNA sequence of a cell. Carcinogens are substances or agents that can cause cancer. While closely related, all carcinogens are typically mutagens, but not all mutagens necessarily lead directly to cancer; they increase the probability of accumulating cancer-causing mutations.
Lipid nanoparticles (lnps)
Lipid nanoparticles are tiny spherical vesicles made of lipids that are used as delivery systems for genetic material, such as mRNA or CRISPR components, into cells. They gained prominence with mRNA vaccines (like COVID-19 vaccines) and are now being engineered with targeting molecules to deliver genetic cargo to specific cell types or organs within the body without needing to remove cells.
What Experts Say About Cancer prevention
- 1.Engaging in just 9 minutes of unstructured exercise snacks daily (three 1-3 minute bursts) can lead to a 40% reduction in all-cause mortality, a 40% reduction in cancer-related mortality, and a 50% reduction in cardiovascular-related mortality.
- 2.Even 10 minutes of vigorous intensity exercise can immediately increase neuronal connections, improve executive function by 14%, and enhance impulse control by boosting plasma serotonin levels.
- 3.Dr. Rhonda Patrick's personal exercise regimen involves 5-6 hours per week, blending high-intensity interval training (HIIT) with strength training (including deadlifts, squats, and cleans, sometimes working down to single reps) alongside running and hiking.
- 4.Prioritizing consistent resistance training and HIIT is crucial for overall health and vitality, even more so than solely focusing on protein intake, though protein remains essential.
- 5.Jumping rope provides unique benefits beyond cardiovascular fitness, specifically contributing to bone density through its weight-bearing nature, which is particularly valuable for banking bone health early in life.
- 6.Consciously avoiding phone use during workouts can significantly enhance the mental and physical resetting aspects of exercise and improve focus.
