The State of Cancer Research

And we already know how small a role the cancer gene plays in the onset of cancer: there has been an 8-fold to 17-fold increase in the incidence of cancer in the last hundred years, but not even one-millionth of 1 percent of that increase can be related to genes.

Genes evolve over hundreds of thousands (if not millions) of years, which means that the so-called cancer gene has had no impact on the huge increase we’ve seen since 1900. Virtually 90 percent of the cancer that we see today cannot possibly have anything to do with genes.

Are nitrosomamine impurities a hot topic?

Posted by Michael A. S. Guth on March 5th, 2025

Yes, nitrosamine impurities have been a significant and hot topic in the pharmaceutical industry and regulatory circles in recent years. Nitrosamines are a class of chemical compounds that can be potentially carcinogenic, and their presence in pharmaceutical products has raised serious safety concerns.

Key Points of Concern:

  1. Regulatory Focus: Regulatory agencies such as the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA), and others have intensified their scrutiny of nitrosamine impurities in drugs. This is due to their potential to cause cancer even at very low levels of exposure.
  2. Widespread Recalls: Several high-profile cases of nitrosamine contamination have led to recalls of widely used medications, including certain batches of angiotensin II receptor blockers (ARBs) like valsartan, and even over-the-counter drugs like ranitidine (Zantac).
  3. Root Causes: Nitrosamines can form during the manufacturing process, often due to the interaction of certain reagents or solvents under specific conditions. They can also arise from degradation of the drug substance or impurities in raw materials.
  4. Analytical Challenges: Detecting and quantifying nitrosamines at very low levels (parts per billion or even parts per trillion) requires advanced analytical techniques, which has been a challenge for both manufacturers and regulators.
  5. Global Impact: The issue has had a global impact, with regulatory agencies worldwide issuing guidelines and requiring manufacturers to assess and mitigate the risk of nitrosamine contamination in their products.

Regulatory Responses:

  • Guidelines and Limits: Regulatory bodies have established strict limits for nitrosamine impurities in pharmaceuticals. For example, the FDA has set interim limits for certain nitrosamines in ARBs.
  • Risk Assessments: Manufacturers are required to conduct thorough risk assessments of their manufacturing processes to identify potential sources of nitrosamine formation.
  • Testing Requirements: Enhanced testing protocols have been mandated to ensure that nitrosamine levels are within acceptable limits.

Industry Actions:

Posted by Michael A. S. Guth on March 4th, 2025

The future of cannabinoid therapy, particularly in the context of targeted mitochondrial activation, is an emerging and promising area of research. Cannabinoids, the active compounds found in cannabis, have been shown to interact with the endocannabinoid system (ECS) and other cellular pathways, influencing various physiological processes. Mitochondria, often referred to as the powerhouses of the cell, play a crucial role in energy production, cellular signaling, and apoptosis (programmed cell death). Here are some key points and potential directions for the future of cannabinoid therapy focused on mitochondrial activation:

1. Mitochondrial Function and Cannabinoids

  • Energy Metabolism: Cannabinoids like CBD (cannabidiol) and THC (tetrahydrocannabinol) have been shown to influence mitochondrial function. CBD, in particular, has been reported to enhance mitochondrial activity and promote cellular energy production.
  • Antioxidant Properties: Cannabinoids exhibit antioxidant properties, which can help mitigate oxidative stress—a key factor in mitochondrial dysfunction. By reducing oxidative damage, cannabinoids may help maintain mitochondrial integrity and function.

2. Neuroprotection and Neurodegenerative Diseases

  • Neurodegenerative Disorders: Conditions such as Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS) are associated with mitochondrial dysfunction. Cannabinoids have shown potential in preclinical studies to protect neurons by enhancing mitochondrial function and reducing oxidative stress.
  • Anti-inflammatory Effects: Chronic inflammation is a common feature of neurodegenerative diseases. Cannabinoids can modulate inflammatory responses, potentially protecting mitochondria from inflammation-induced damage.

3. Cancer Therapy

  • Apoptosis Induction: Some cannabinoids have been found to induce apoptosis in cancer cells by targeting mitochondrial pathways. This could lead to the development of cannabinoid-based therapies that selectively induce cancer cell death while sparing healthy cells.
  • Mitochondrial Membrane Potential: Cannabinoids can alter the mitochondrial membrane potential, leading to the release of pro-apoptotic factors and subsequent cell death in cancer cells.

4. Metabolic Disorders

  • Obesity and Diabetes: Mitochondrial dysfunction is implicated in metabolic disorders such as obesity and type 2 diabetes. Cannabinoids may help improve mitochondrial function and insulin sensitivity, offering a potential therapeutic avenue for these conditions.
  • Lipid Metabolism: The ECS plays a role in lipid metabolism, and cannabinoids can influence lipid accumulation and mitochondrial biogenesis, which are critical for metabolic health.

5. Cardiovascular Health

  • Cardioprotection: Cannabinoids have been shown to have cardioprotective effects, partly through their actions on mitochondria. By enhancing mitochondrial function and reducing oxidative stress, cannabinoids may help protect against ischemic heart disease and other cardiovascular conditions.

6. Targeted Delivery Systems

  • Nanotechnology: Advances in nanotechnology could enable the targeted delivery of cannabinoids to specific tissues or cells, enhancing their therapeutic effects on mitochondria while minimizing side effects.
  • Mitochondrial Targeting: Developing cannabinoid derivatives or conjugates that specifically target mitochondrial membranes could improve the efficacy and precision of cannabinoid therapy.

7. Personalized Medicine

  • Genetic and Epigenetic Factors: Understanding the genetic and epigenetic factors that influence individual responses to cannabinoids could lead to personalized cannabinoid therapies tailored to optimize mitochondrial function based on a person’s unique genetic makeup.

8. Regulatory and Ethical Considerations

  • Clinical Trials: Rigorous clinical trials are needed to establish the safety and efficacy of cannabinoid therapies targeting mitochondrial function. Regulatory frameworks will need to adapt to accommodate these new therapeutic approaches.
  • Ethical Implications: As with any emerging therapy, ethical considerations regarding access, equity, and potential misuse must be addressed.

Conclusion

The future of cannabinoid therapy focused on targeted mitochondrial activation holds significant promise for treating a wide range of diseases, from neurodegenerative disorders to cancer and metabolic conditions. However, much research is still needed to fully understand the mechanisms involved and to develop safe, effective, and targeted therapies. As the field advances, interdisciplinary collaboration between researchers, clinicians, and policymakers will be essential to realize the full potential of cannabinoid-based mitochondrial therapies.

Reflections on AGING

Posted by Michael A. S. Guth on February 9th, 2025

From join1440.com

“Background

Aging is the progressive decline of the human body’s function that results from a combination of genetic, environmental, and metabolic factors. As our cells accumulate damage, important systemic processes within the body become dysregulated, leading to an increased rate of disease and mortality (see overview here).

The global population is aging at an unprecedented rate, a phenomenon that carries significant social and economic challenges. Societies are investing heavily in the fight against aging—a recent analysis revealed that a slowdown of aging by just one year could be worth $38T in the US alone.

What Happens to the Body

As we age, our cells accumulate damage on many fronts, including mutations in DNA (the information code of our cells), shortening of telomeres (protective end caps on DNA strands), and epigenetic alterations (changes in how our cells read DNA information).

This causes our microscopic machinery to go awry. The result is decreased cellular function, impaired mitochondrial energy production, and less efficient repair mechanisms. Read more about the causes of cellular aging.

As our body’s building blocks break down, our organs and tissues experience an associated loss of structure and function. This results in a cycle of inflammation and tissue fibrosis that reduces the functional capacity of our vital organs.

All of these microscopic changes add up to what we see as “getting older.” Our bones lose the ability to resist stress (i.e., osteoporosis), the structural integrity of our skin fails (i.e., wrinkles), our heart no longer pumps with the necessary strength (i.e., heart failure), and we are more at risk of injury and disease.

What Happens to the Brain

The same cellular- and tissue-level changes associated with aging have a particularly destructive effect on our brains.

As cellular function decreases, inflammation rises and the accumulation of cellular waste disrupts the ability of our brain cells to talk to each other. This impairs our processing of complex cognitive tasks and weakens our memory (what happens to your brain through life).

These neurologic changes often translate to depression, social withdrawal, and increased susceptibility to diseases like Alzheimer’s and Parkinson’s dementia.

Chronological Versus Biological Aging

While the most familiar convention of measuring age is “chronological” (that is, measuring age in years), there is an emerging interest in determining “biological age.”

This method uses formulas or blood test results to estimate the cellular age of a person. In other words, biological age is not a function of time but rather of how well cellular and organ systems are functioning in each individual. In this way, interventions such as exercise, healthy lifestyles, and perhaps even medications could reverse one’s biological age—all while their chronological age increases.

While some testable biomarkers have emerged as candidates (e.g., the epigenetic clock), there is ongoing research to uncover simple, reliable means to measure and track one’s biological age over time.

Lifespan Versus Healthspan

While tremendous recent progress has been made in the field of aging, the emphasis has begun to shift from extending lifespan (the number of years one is alive) to maximizing an individual’s healthspan (the number of years one is active and without disease).

Researchers emphasize a holistic approach to nurturing your healthspan, including consistent daily movement and exercise, high-quality sleep hygiene, a balanced diet with whole foods, and more.”

Patient Compliance, Investigator Compliance, and More Compliance

Posted by Michael A. S. Guth on February 9th, 2025
  1. Importance of Compliance: Compliance (adherence to the study protocol by participants and researchers) is a cornerstone of successful clinical trials. Poor compliance can lead to unreliable results, increased costs, and even trial failure.
  2. Types of Compliance:
    • Participant Compliance: Refers to how well participants follow the trial protocol, including taking medications as prescribed, attending scheduled visits, and completing required procedures.
    • Investigator Compliance: Involves adherence by researchers to the trial protocol, including proper data collection, reporting, and ethical conduct.
  3. Consequences of Non-Compliance:
    • Non-compliance by participants can lead to biased outcomes, reduced statistical power, and difficulty in interpreting results.
    • Non-compliance by investigators can result in protocol violations, ethical issues, and compromised data integrity.
  4. Factors Affecting Compliance:
    • Participant Factors: Lack of understanding, forgetfulness, side effects, and personal beliefs can reduce participant compliance.
    • Trial Design Factors: Complex protocols, frequent visits, and burdensome procedures can discourage participation and adherence.
    • Investigator Factors: Inadequate training, lack of resources, and poor communication can lead to non-compliance by researchers.
  5. Strategies to Improve Compliance:
    • Participant Engagement: Educating participants about the importance of the trial, simplifying protocols, and providing reminders (e.g., phone calls, text messages) can enhance adherence.
    • Investigator Training: Ensuring researchers are well-trained and motivated to follow protocols strictly.
    • Monitoring and Feedback: Regular monitoring of compliance and providing feedback to participants and investigators can help identify and address issues early.
    • Incentives: Offering incentives (e.g., financial compensation, travel reimbursement) can improve participant retention and adherence.
  6. Technological Solutions: Leveraging technology, such as electronic monitoring devices and mobile apps, to track and improve compliance.
  7. Ethical Considerations: Ensuring compliance should not compromise ethical standards. Participants must provide informed consent, and their autonomy and well-being should always be prioritized.
  8. Conclusion: Compliance is not just a minor detail but a fundamental aspect of clinical trial success. Addressing compliance proactively through thoughtful trial design, participant engagement, and investigator training is essential for generating reliable and valid results.

Best podcast episode of all the podcasts in 2024

Posted by Michael A. S. Guth on December 18th, 2024

The best single episode of any podcast (subscribe to 70) that I have heard this year. The episode is so good, I will probably repost this message a couple times in 2025.

“In 1962, President John F. Kennedy said, “Those who make peaceful revolution impossible will make violent revolution inevitable.”

It was a recognition of a universal truth in human history: Social stability, the rule of law, and civilization will eventually break down if a population is immiserated for too long while a handful of elites profit. And just two months after that speech, Kennedy honed in on the health care crisis in America, pressing for the passage of what would become Medicare. ”

“What we are now talking about doing, most of the countries of Europe did years ago,” he said at a Madison Square Garden rally. “We are behind every country, pretty nearly, in Europe, in this matter of medical care for our citizens.”

I’ve been thinking a lot about that moment in history in light of the news over the past week. All of a sudden, after the murder of UnitedHealthcare CEO Brian Thompson, everyone is talking about health care, even though almost nobody was talking about it during the presidential campaign.

David Sirota reflects on the shocking murder of United Health CEO Brian Thompson and the surge of public anger it unleashed against America’s broken health insurance system. Why hasn’t this longstanding outrage translated into universal health care — a system every other wealthy nation already has?

Tracing decades of broken promises and corporate influence — from the Clinton and Obama administrations to today — Sirota looks at how political corruption has trapped Americans in a system that profits from their suffering. Drawing on JFK’s 1960s warnings about social stability and justice, this audio essay explores the health care crisis as a symptom of a deeper democracy crisis — and asks what it will take for Americans to finally demand change.
