The Legacy of Dolly the Sheep May Be Your Future Health

The first mammal cloned from an adult cell, Dolly the sheep. In 1997, The Roslin Institute introduced Dolly to the world. It caused a frenzy of attention. In the twenty-five years since Dolly’s birth, we have cloned many more species of animals with little fanfare. In February 2021, scientists announced they’d successfully cloned the first U.S. endangered species, the black-footed ferret. The ferret is just one part of Dolly’s legacy. The other part of the legacy of Dolly the sheep may be your future health. The Life of Dolly the Cloned Sheep Born on July 5th 1996, Dolly’s white face confirmed she was a clone. The black-faced surrogate ewe who birthed her could not be her genetic mother. Scientists tested Dolly’s DNA when she was one. They discovered that her DNA telomeres (end caps) were shorter than expected. Scientists thought that since the cells used to create Dolly came from an adult sheep may have caused the abnormality. They thought the adult cells somehow prevented her telomeres from developing normally. At two, Dolly mated with a Welsh Mountain ram called David. Dolly gave birth to a female lamb in 1998,. She had twin lambs the next year and triplets in […]

Type 1 Diabetes Research-What You Need to Know

Recently researchers at LJI reported they prevented beta cell deaths in mice by blocking nerve signals to the pancreas. Why is this important? They may be one step closer to understanding what causes diabetes. The hope is that understanding will lead to a cure. This is what you need to know. What is the Pancreas? Your pancreas is about six inches long. It lies in the back of the abdomen, on your right side behind your liver. The pancreas creates a cocktail of juices called enzymes.  These enzymes travel from the pancreas through a duct to the upper part of your intestine. There they break down the food you eat into fats, proteins, and starches. Your pancreas also produces hormones that carry messages to other parts of your body. (Read more about the pancreas.) One hormone the healthy pancreas makes is insulin. It makes insulin in specialized cells called beta cells. What is Type I Diabetes Nearly 1.6 million Americans have a life-threatening, but treatable condition. Their beta cells die. When their beta cells die, their bodies do not produce insulin. It happens in every race, gender, and body size and shape. Even mammals can have type I diabetes. Without […]

How Long Do You Want to Live?

If you could choose, how long do you want to live? To 100, 200, 500 years of age? Perhaps your answer is, it depends—will I be healthy? By the end of this decade, nearly 1 in 5 Americans will be 65 or older. Three out of 4 will have two or more serious health conditions. At least 1 in 4 can expect memory lapses and fuzzy thinking, while 1 in 10 will develop dementia. You’re not part of the generation known as the Boomers? Don’t worry. You’ll age, too.  Aging-Factors that Cause Disease The research is extensive. And unfortunately, there isn’t just one thing that leads to age-related diseases. There are many: inflammation; a metabolism system that doesn’t work right; inactive stem cells; stress-related damage, environmental toxins, and more. These problems of aging cells lead to diseases like heart disease, stroke, diabetes, osteoarthritis, Alzheimer’s disease, Parkinson’s, and cancer. Fortunately, there’s been a “perfect storm” in anti-aging research. All kinds of treatments for age-related illnesses are moving into or already in clinical trials. They aim to make us grow old in better health. If you could grow old in good health, how long do you want to live? Anti-Aging Research A new class […]
