Aging, Senescence and Insulin-Like Growth Factors

aging senescence
One approach to understanding the senescent growth arrest is to examine the factors that are required for the division of young cells and to determine whether the senescent cells are able to respond to these factors. Any defect in their response would presumably shed light on the mechanism of the growth arrest. In virtually all cell types, cell division is regulated by the presence of growth factors. Growth factors are small proteins that bind to specific receptors on the surface of cells. The receptors for growth factors contain intrinsic enzymatic activity that is activated by growth factor binding. (more…)

Overview of Hormonal Changes with Age

Altered cellular metabolism and intracellular and intercellular signaling with advancing age result in widespread changes in endocrine function. Several mechanisms interact in most systems to bring about the observed changes. Aging is associated with anatomic changes of the endocrine glands. In addition, with age, changes in hormone secretion occur, including alterations in circadian or seasonal biorhythms, changes in pulsatile frequency or amplitude of hormone secretion, as well as absolute changes in mean serum hormonal levels.

Hormonal Changes with Age – An Overview

Altered cellular metabolism and intracellular and intercellular signaling with advancing age result in widespread changes in endocrine function. Several mechanisms interact in most systems to bring about the observed changes. Aging is associated with anatomic changes of the endocrine glands. In addition, with age, changes in hormone replacement secretion occur, including alterations in circadian or seasonal biorhythms, changes in pulsatile frequency or amplitude of growth hormone secretion, as well as absolute changes in mean serum hormonal levels. The three main hormone systems that show decline with age are the gonadal hormones (menopause and andropause), the adrenal steroids DHEA and DHEA-S (adrenopause), and the GH/IGF-1 axis (somatopause).

Anabolic Therapies For Elderly

Involuntary weight loss is the result of many chronic progressive diseases, often leading to diminished lean body mass, frailty, susceptibility to illness, and increased mortality. Various anabolic agents have been used to combat weight loss with mixed results. Similar to the frustration experienced by advocates of weight loss in the obese, none of the pharmacological appetite stimulants available at the current time have been uniformly successful in combating involuntary weight loss in the elderly population.

Growth Hormone Replacement in Adults and Elderly

Growth Hormone Replacement
The systemic benefits of exogenous Growth Hormone therapy in the healthy elderly remain unclear and controversial. Studies have not been able to demonstrate a clear anabolic effect of replacement of Growth Hormone in elderly subjects, possibly because Growth Hormone replacement cannot completely correct the alterations in binding recommended proteins.

Estrogen-Progestin Hormone Replacement Therapy?

hormone replacement therapy
When approaching menopause or during post-menopause period, most women suffered from menopausal symptoms irritability like hot flashes, vaginal dryness, urination difficulty, night sweats and osteoporosis.

All symptoms above were as the result of your body reducing hormone production as you are aging. It may start as early as age 25 for women, and hormone level production reduce significantly until menopause period. (more…)
