Protective gene variant becomes bad actor on high-fat diet

harminka — Tue, 06 Jan 2009 14:29:37 -0600

New evidence in mice bolsters the notion that a version of a gene earlier shown to protect lean people against weight gain and insulin resistance can have the opposite effect in those who eat a high-fat diet and are heavier, reveals a report in the January 7th issue of the journal Cell Metabolism, a Cell Press publication.

Vitamin K linked to insulin resistance in older men

Vitamin K slowed the development of insulin resistance in elderly men in a study of 355 non-diabetic men and women ages 60 to 80 who completed a three-year clinical trial at the Jean Mayer Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA).

Inheritance of hormonal disorder marked by excessive insulin in daughters

Elevated levels of insulin could be an early sign that girls whose mothers suffer from polycystic ovary syndrome -- or PCOS -- may also be susceptible to the disease, according to gynecologists who have found evidence of insulin resistance in young children.

Lifestyle can alter gene activity, lead to insulin resistance

A Finnish study of identical twins has found that physical inactivity and acquired obesity can impair expression of the genes which help the cells produce energy. The findings suggest that lifestyle, more than heredity, contributes to insulin resistance in people who are obese.

Is There A Link Between Frailty And Insuline Resistance

Armen Hareyan — Sun, 30 Mar 2008 13:26:27 -0500

Two of the great scourges of old age are insulin resistance (often leading to late-onset diabetes) and frailty (a suite of symptoms that may have their roots in runaway inflammatory signaling). A review by Paolisso and Abbatecola investigates the possible connections between the two:

Novel link between excessive nutrient levels and insulin resistance

For quite some time now, scientists suspected the so-called hexosamine pathway — a small side business of the main sugar processing enterprise inside a cell — to be involved in the development of insulin resistance. But they could never quite put their finger on the underlying mechanism.

How does insulin influence resistin?

harminka — Wed, 16 Jan 2008 09:07:28 -0600

Obesity is a worldwide health problem directly linked to several diseases such as hypertension and type 2 diabetes. Resistin is a cysteine-rich hormone mainly secreted by adipose tissues and may form a biochemical link between obesity and type 2 diabetes.

Morbidly obese mice gain protection against diabetes

harminka — Fri, 24 Aug 2007 13:08:15 -0500

The “world’s fattest mice” can overeat without developing insulin resistance or diabetes thanks to a glut of a key hormone, a dichotomy that helps explain why not all obese people are diabetic, a UT Southwestern Medical Center researcher has found.

Fat on chest increases risk of insulin resistance

harminka — Mon, 20 Aug 2007 03:46:32 -0500

Upper trunk fat – deposits of fat on the chest and back –– is associated with an increased risk of insulin resistance, a condition that is a precursor of type 2 diabetes, according to a study led by researchers at the San Francisco VA Medical Center (SFVAMC).

New clue into how diet, exercise enhance longevity

harminka — Fri, 20 Jul 2007 04:00:34 -0500

The traditional prescriptions for a healthy life—sensible diet, exercise and weight control—extend life by reducing signaling through a specific pathway in the brain, according to Howard Hughes Medical Institute researchers who discovered the connection while studying long-lived mice.

New blood test to offer warning of deep belly fat

Measuring levels of a chemical found in blood offers the best indicator yet of the amount of fat surrounding abdominal organs, according to a new study of lean and obese individuals reported in the July issue of Cell Metabolism, a publication of Cell Press.
