Fructose-Induced Metabolic Dysfunction Is Dependent on the Baseline Diet, the Length of the Dietary Exposure, and Sex of the Mice.

High sugar intake, particularly fructose, is implicated in obesity and metabolic complications. On the other hand, fructose from fruits and vegetables has undisputed benefits for metabolic health. This raises a paradoxical question-how the same fructose molecule can be associated with detrimental health effects in some studies and beneficial in others.

The propensity of fructose to induce metabolic dysfunction is dependent on the baseline diet, length of the dietary exposure, and sex of the mice.

Background/objectives: Numerous studies have implicated high intake of sugar, particularly fructose, with the development of obesity and metabolic complications. On the other hand, fructose from fruits and vegetables has undisputed benefits for metabolic health. This paradox questions how the same fructose molecule can be associated with detrimental health effects in some studies and beneficial in others.

Knockdown of ketohexokinase versus inhibition of its kinase activity exert divergent effects on fructose metabolism.

Excessive fructose intake is a risk factor for the development of obesity and its complications. Targeting ketohexokinase (KHK), the first enzyme of fructose metabolism, has been investigated for the management of metabolic dysfunction-associated steatotic liver disease (MASLD). We compared the effects of systemic, small molecule inhibitor of KHK enzymatic activity with hepatocyte-specific, N-acetylgalactosamine siRNA-mediated knockdown of KHK in mice on an HFD.

Growth Hormone Treatment Normalized Liver Enzymes in an Adolescent with Obesity and Short Statute.

Metabolic Dysfunction Associated Steatotic Liver disease is the most common cause of chronic hepatitis in children and adults. The patients with MASLD have low thyroid hormone activity in the liver. Recent evidence suggests that patients with MASLD may also have haptic growth hormone deficiency.

The combined pioglitazone and topiramate therapy for management of pediatric patients with severe MASLD.

Background: Metabolic dysfunction associated steatotic liver disease (MASLD) is the most common cause of chronic hepatitis in adult and pediatric patients. Adolescents with severe MASLD can demonstrate a more aggressive disease phenotype as they more commonly develop liver fibrosis than BMI matched adults. Therefore, MASLD is the fastest growing indication for liver transplants in young adults.
