Leptin resistance during aging is independent of fat mass
I Gabriely, XH Ma, XM Yang, L Rossetti, N Barzilai - Diabetes, 2002 - Am Diabetes Assoc
Increased fat mass, abdominal adiposity, and insulin resistance are typical findings in aging
mammals and are frequently associated with leptin resistance and increased plasma leptin …

Aging is associated with resistance to effects of leptin on fat distribution and insulin action
XH Ma, R Muzumdar, XM Yang… - The Journals of …, 2002 - academic.oup.com
Leptin has been shown to modulate total body fat and visceral fat distribution and to
enhance insulin action in young rats. We hypothesize that failure of leptin action may …

Role of leptin resistance in the development of obesity in older patients
Obesity is a global epidemic associated with aging-like cellular processes; in both aging and
obesity, resistance to hormones such as insulin and leptin can be observed. Leptin is a …

Transgenic mice overexpressing leptin accumulate adipose mass at an older, but not younger, age
J Qiu, S Ogus, R Lu, FF Chehab - Endocrinology, 2001 - academic.oup.com
Sensitivity to leptin is associated with a normal regulation of the adipose mass, whereas
decreased leptin sensitivity results in elevated adipose tissue stores. To address whether …

Leptin and aging: Review and questions with particular emphasis on its role in the central regulation of energy balance
Leptin is produced mainly in the white adipose tissue and emerged as one of the key
catabolic regulators of food intake and energy expenditure. During the course of aging …
