Anyone with an annoying roommate story knows what a difficult living situation can change you in many ways. Now, imagine that instead of just eating your food in the refrigerator, that could be more tolerant of their behavior.
Does it sound too good to be true? Well, this is exactly what has happened in the case of some of the most important things in the world, such as stinging insects and pungent food sources.
I am a behavioral geneticist studying how to reduce the risk of cancer. My goal is to improve the treatment of opioids.
These are a powerful tool to treat bread, particularly acute bread, but they do not specifically target a specific breadmaking mechanism or signal. Instead, opioids primarily act to decrease the ability of cells to transmit messages.
These creatures have evolved insensitivity to very specific types of painful stimuli. This occurs as a result of subtle differences in gene activity and protein structure, rather than deletions or mutations of genes.
It is becoming more widely accepted than these types of differences in the development of chronic pain.
More importantly, it would be a natural lead to innovative methods for safe and effective breadcrumbs.
Stinky burrows drive
Naked mole rats (Heterocephalus glaber) are native to East Africa and live in densely populated underground burrows. Inside these burrows, the exhaled carbon dioxide levels are so high that the air becomes so acidic that it would cause a painful burning sensation in the nose, eyes and exposed skin of most mammals.
But the naked mole rat is completely insensitive to these high acid conditions, making it extremely tolerant of all that togetherness. These are also insensitive to capsaicin, the chemical responsible for the burning bread of chili peppers.
New research led by Gary Lewin, a sensory system physiologist in Berlin, Germany, reveals that naked moles are not the only African elephants that have evolved to tolerate tough living conditions.
Throughout the world, the results of this study have been shown to be completely insensitive to at least one of three painful substances: acid, capsaicin or AITC, which is the active ingredient in mustard oil.
All of these stimuli cause different types of bread. The acid is the one that mimics the high carbon dioxide in the burrow. The capsaicin and mustard oil (AITC) – which causes a burning pain – are found in typical foods that the naked mole rats eat. But each cause causes a different biochemical pathway.
Implications for the opioid crisis
The evidence points to the insensitivity to acid, capsaicin and AITC all evolving separately in related rodent species. But in the end these adaptations help these rodents survive and thrive in their hot, dark and acidic environments.
Without major alterations in structure and function of the pain-sensing pathway in their bodies, these principles have evolved multiple ways of reducing their sensitivity to common painful stimuli. In short, they relate to one another to become uber-tolerant to their living conditions and their roommates.
In my mind, understanding the molecular changes that allow the naked mole rat and its relative to become resistant to certain types of bread has implications far beyond the rodent roommate market. They are not directly involved in the treatment of allergic diseases.
The misuse, misuse and addiction of mischief, misuse, and mischief.
