Researchers have found that kinesin family member 9 (KIF9), a protein that diminishes with aging, is instrumental in allowing cells to consume harmful proteins and fights Alzheimer's in a mouse model. Consuming amyloids before they become a problem Alzheimer's is well-known as a proteostasis disease: it is characterized by amyloid beta plaques outside the cells...

Boosting a key autophagy-related protein discourages a core component of Alzheimer's from taking hold, according to a study published in Aging Cell. Taking out the trash Autophagy is the maintenance process of the cell, in which autophagosomes engulf unwanted organelles and other material and fuse together with lysosomes to be digested. As these unwanted components...

Researchers have published a method of rescuing cells from damaged mitochondria and cellular senescence, potentially alleviating major aspects of aging. Bad mitochondria must be consumed A core part of autophagy involves selective autophagy receptors (SARs), which build the autophagosomes in which the organelles are consumed [1]. Mitophagy is a subset of autophagy that refers to...

A study published in Human Nutrition & Metabolism found that prolonged intermittent fasting causes the expression of genes involved in autophagy, the inflammasome, and senescence to change [1]. Fasting your way to better health and longevity? Previous research has linked fasting to delaying the onset of age-related diseases and longevity along with positive outcomes in...

A study published in Aging Cell has reported that older people with better regulated autophagy in their skeletal muscles have less age-related frailty. Taking out the trash The researchers begin this paper by discussing the various activities and effects of autophagy. Obviously, too much autophagy is not good, as it aggravates tissue degeneration [1], but...

Experimenting in vitro and in mice, scientists have found that ovarian aging is linked to increased autophagy and apoptosis in granulosa cells and that it can be reversed by an estrogen receptor inhibitor [1]. When ovaries get tired Female reproductive aging is an intriguing phenomenon that remains understudied, although things have been changing recently. In...
