Mitochondrial and sex steroid hormone crosstalk during aging

چکیده

Decline in circulating sex steroid hormones accompanies several age-associated pathologies which may influence human healthspan. Mitochondria play important roles in biosynthesis of sex steroid hormones, and these hormones can also regulate mitochondrial function. Understanding the cross talk between mitochondria and sex steroid hormones may provide insights into the pathologies associated with aging. The aim of this review is to summarize the current knowledge regarding the interplay between mitochondria and sex steroid hormones during the aging process. The review describes the effect of mitochondria on sex steroid hormone production in the gonads, and then enumerates the contribution of sex steroid hormones on mitochondrial function in hormone responsive cells. Decline in sex steroid hormones and accumulation of mitochondrial damage may create a positive feedback loop that contributes to the progressive degeneration in tissue function during aging. The review further speculates whether regulation between mitochondrial function and sex steroid hormone action can potentially influence healthspan.

Role of Sex Hormones on Brain Mitochondrial Function, with Special Reference to Aging and Neurodegenerative Diseases

The mitochondria have a fundamental role in both cellular energy supply and oxidative stress regulation and are target of the effects of sex steroids, particularly the neuroprotective ones. Aging is associated with a decline in the levels of different steroid hormones, and this decrease may underline some neural dysfunctions. Besides, modifications in mitochondrial functions associated with agi...

The neuroprotective steroid progesterone promotes mitochondrial uncoupling, reduces cytosolic calcium and augments stress resistance in yeast cells

The steroid hormone progesterone is not only a crucial sex hormone, but also serves as a neurosteroid, thus playing an important role in brain function. Epidemiological data suggest that progesterone improves the recovery of patients after traumatic brain injury. Brain injuries are often connected to elevated calcium spikes, reactive oxygen species (ROS) and programmed cell death affecting neur...

The correlation of anandamide with gonadotrophin and sex steroid hormones during the menstrual cycle

Objective(s): The purpose of this study was to investigate the change in plasma anandamide (AEA) levels throughout the normal menstrual cycle, and to analyze the relationship among AEA, sex steroids and gonadotrophins. Materials and Methods: The patients were fertile women with normal menstrual cycle, proposed to get in vitro fertilization (IVF) treatment due to oviduct obstruction or male infe...

Sandifish (Holothuria scabra) ameliorates aging in menopausal women by increasing estradiol hormones

Introduction: Sandfish (Holothuria scabra) is a marine species generally sold as a raw material that has been dried even though the meat contains steroid hormone with high economic value, which has the potential to become a source of safe natural steroid hormone. This study was aimed to look at the potency of sandfish as an anti-aging for menopausal women. Sandfish could become a source of natu...

The rate of change in declining steroid hormones: a new parameter of healthy aging in men?

Research on healthy aging in men has increasingly focused on age-related hormonal changes. Testosterone (T) decline is primarily investigated, while age-related changes in other sex steroids (dehydroepiandrosterone [DHEA], estradiol [E2], progesterone [P]) are mostly neglected. An integrated hormone parameter reflecting aging processes in men has yet to be identified. 271 self-reporting healthy...
