Cellular Senescence Promotes Malignant Brain Tumor Growth
Senescent cells act to suppress risk of cancer its very earliest stage. The pro-inflammatory secretions of cells made senescent as a result of mutational damage and the response of tumor suppressor genes attract the immune system to places in which damaged cells may give rise to a tumor. When senescent cells are present in larger numbers, and linger over time, as is the case in aged tissues, they actively encourage tumor growth, however. Here, researchers produce a compelling demonstration of this harmful consequence of cellular senescence, categorizing and eliminating senescent cells present in glioblastoma tumors in mice...

In this study, we develop a rFOXN1 fusion protein that contains the N-terminal of CCR9, FOXN1, and TAT. We show here that, when injected intravenously (i.v.) into aged mice, the rFOXN1 fusion protein can migrate into the thymus and enhance T cell generation in the thymus, resulting in increased number of peripheral T cells. Our results suggest that the rFOXN1 fusion protein has the potential to be used in preventing and treating T cell immunodeficiency in the older adult.

Alpha TAU Killing Tumors With Highly Targeted Alpha Radiation
Radiation is commonly employed in hospitals around the world to treat tumors, typically using gamma ray beams of high energy photons, with a relatively long range, that penetrate all the tissues on the way to and from the tumor. This leads to substan...

This study tested the hypothesis that ischemic vascular repair in aging by Ang-(1-7) involves attenuation of myelopoietic potential in the bone marrow and decreased mobilization of inflammatory cells.
Young or Old male mice of age 3-4 and 22-24 months, respectively, received Ang-(1-7) for four weeks. Myelopoiesis was evaluated in the bone marrow (BM) cells by carrying out the colony forming unit (CFU-GM) assay followed by flow cytometry of monocyte-macrophages. Expression of pro-myelopoietic factors and alarmins in the hematopoietic progenitor-enriched BM cells was evaluated. Hindlimb ischemia (HLI) was induced by ...

In this study, researchers stimulate the ghrelin receptor using a suitable small molecule for much of the lifespan of mice, and observe the results. The overall extension of life span is a quarter of that produced by calorie restriction, and so we might draw some conclusions from that as to the relative importance of hunger in the benefits resulting from the practice of calorie restriction or fasting. Interestingly, the short term weight gains observed in mice given this ghrelin receptor agonist in the past don't appear in this long term study, in which the controls are the heaver animals. This is possibly because the rese...

Nanowire Assay Detects Brain Tumors from Urine
Researchers at Nagoya University in Japan have developed a nanowire assay that can be used to capture and detect specific extracellular vesicles in a urine sample that indicate the presence of a brain tumor. These extracellular vesicles are naturally...

This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed.
The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

Microglial Autophagy in the Context of Neurodegenerative Conditions
Changes in the function and activity of microglia in the brain, innate immune cells analogous to the macrophages present in the rest of the body, are known to be involved in the onset and progression of neurodegenerative conditions. Aging and neurodegeneration are associated with a growing presence of both senescent microglia and activated microglia Both of these states producing inflammatory signaling, contributing to the chronic, unresolved inflammation of brain tissue that is also characteristic of later life.
Autophagy is the name given to a collection of cellular maintenance processes responsible for recycling ...

Ultrasound is Ultra-Cool
This study is also a major step forward for the exciting possibility of combining focused ultrasound with targeted delivery of medications or antibodies that normally have limited capability to cross the blood brain barrier from the blood to the brain.”
Similarly, researchers at Yonsei University College of Medicine (South Korea) found that focused ultrasound improved the delivery of Alzheimer’s drugs by over eight times. “While there is no complete cure for dementia, we hope that open BBB [blood brain barrier] surgery using FUS surgery can help give hope to dementia patients,” the lead researcher said.

This study explored the association between tap drinking water and longevity in Cilento, Italy, to understand whether trace elements in local drinking water may have an influence on old, nonagenarian, and centenarian people and promote their health and longevity.
Data on population and water sources were collected through the National Demographic Statistics, the Cilento Municipal Archives, and the Cilento Integrated Water Service. Ordinary least squares (OLS) regression and a geographically weight regression (GWR) model were used to study the spatial relationship between the explanatory and outcome variables of long...

ADAR1 in Immunity and Aging
This short overview skims recent work on the role of ADAR1 expression in aging. Levels of ADAR1 are reduced with age in many tissues, and this may affect a number of processes relevant to aging, such as cellular senescence. ADAR1 edits RNA, affecting the behavior of gene expression at a very low level. It is a good example of a protein that is thus involved in many, many processes in the cell, and which has indirect effects on any number of cell behaviors. It is exceptionally challenging to pin down specific important roles for such proteins. There is such a large space of possibilities to cover that decades of work may or...
