In the world of tiny molecules, long noncoding RNAs (lncRNAs) are like secret bosses. They don't make proteins, but they control many important jobs in our cells. One of these bosses, TMEM9B-AS1, has been found to be less active in the muscles of people with type 2 diabetes and muscle loss. This is a big deal because it might be a key player in muscle health. Scient...
The way our muscles grow and change with exercise isn't the same for everyone, especially as we get older. This is because muscle loss due to aging doesn't happen evenly across all muscle groups. So, it's important to look at how different muscles react to exercise in older adults. A lot of studies have been done on this topic. Over 6000 research papers were looked ...
The offspring of mothers with gestational diabetes often face long-term health challenges. These include problems with their skeletal muscles. Traditional treatments mostly focus on controlling blood sugar levels. However, they do not address the underlying changes in muscle metabolism and structure. This is where theabrownin (TB), a compound found in Pu-erh tea, com...
Oxygen shortage, whether from high altitudes or health issues, can shrink muscles. This is because the body struggles to build and repair muscle tissue when oxygen is scarce. Traditional methods to fight this muscle loss, such as moving to lower altitudes, exercising, or taking supplements, often fall short for those with severe oxygen deprivation. Scientists have...
Insulin is a crucial player in how our bodies handle sugar. It sends signals to our muscles to absorb glucose from the bloodstream. For a long time, scientists thought insulin boosted the production of hydrogen peroxide in muscle cells. This would then tweak certain proteins, affecting how insulin works. However, this idea has been hard to prove, especially in human ...
You might think that only being overweight can lead to high blood pressure. But hold on, there's more to it! A study of young African women found something surprising. It turns out that the amount of muscle you have can also affect your blood pressure. The study looked at 1, 162 women and found that those with more muscle mass had higher blood pressure. This was tru...
When you think of diabetes, you probably picture how it affects your blood sugar. But did you know it also messes with how your muscles use fat? That's what we're diving into here. You see, diabetes ties into a whole bunch of health issues, including how your muscles handle fat. When fat builds up in your muscles and causes stress in the powerhouses called mitochond...
Do you know that muscles can store fat? Inside muscle cells, there's intramyocellular lipid (IMCL) and outside, it's called extramyocellular lipid (EMCL). Then, there's fat between muscles, known as intermuscular adipose tissue (IMAT). Scientists think these fats play a role in energy production in our muscles. But does muscle oxidative capacity, which affects energy...
Young Japanese adults, both men and women, were studied to see how their daily diet links to the amount of muscle in their trunk and the presence of fat within those muscles. This study focused on people aged 20 to 26. To measure trunk muscle thickness (MT) and echo intensity (EI), which shows how much non-contractile tissue like fat is present, ultrasound was used a...
Skeletal muscle dysfunction (SMD) is a serious problem for folks with chronic obstructive pulmonary disease (COPD). It affects how well they get better and live their lives. Mitochondria, the powerhouses of cells, play a big role in this. They keep their networks in check through something called mitochondrial quality control (MQC). This process involves making new m...
