Computational Simulations to Guide Cancer Therapy
Researchers from Argonne National Laboratory and University of Chicago have developed a new supercomputer-based tool to model tumor progression and destruction by the immune system. Their work demonstrates that computational simulations of immune-tum...

In this study, we identify a link between members of the genus Veillonella and exercise performance. We observed an increase in Veillonella relative abundance in marathon runners postmarathon and isolated a strain of Veillonella atypica from stool samples. Inoculation of this strain into mice significantly increased exhaustive treadmill run time.
Veillonella utilize lactate as their sole carbon source, which prompted us to perform a shotgun metagenomic analysis in a cohort of elite athletes, finding that every gene in a major pathway metabolizing lactate to propionate is at higher relative abundance postexercise. Us...

In this study, analysis of antioxidant defense was performed on the blood samples from 184 "aged" individuals aged 65-90+ years, and compared to the blood samples of 37 individuals just about at the beginning of aging, aged 55-59 years. Statistically significant decreases of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were observed in elderly people in comparison with the control group. Moreover, an inverse correlation between the activities of SOD-1, CAT, and GSH-Px and the age of the examined persons was found. No age-related changes in glutathione reductase activiti...

Recap of the first day of the AANP annual meeting
Dr. Maria Martinez-Lage was kind enough to write the following summary of events at today ’s American Association of Neuropathologists meeting in Atlanta:The opening day of the 95th Annual Meeting of the American Association of Neuropathologists in Atlanta featured a special course dedicated to a topic both old and new: what happens when treatments go awry? Under the title “Unintended Consequences: The Iatrogenic Neuropathology of Systemic Therapies” the faculty discussed neurologic adverse effects of novel immunotherapies,other cancer and non-cancer related treatments, a...

Senolytic Therapies to Clear Senescent Cells Should Benefit Cancer Patients
It is well known that the present dominant approaches to cancer therapy - meaning toxic, damaging chemotherapy and radiotherapy, only slowly giving way to immunotherapy - produce a significant burden of senescent cells. Indeed, forcing active cancer cells into senescence is the explicit goal for many treatments, and remains an aspirational goal for a large fraction of ongoing cancer research. Most senescent cells self-destruct, or are destroyed by the immune system, but some always linger - and more so in older people, due to the progressive incapacity of the immune system. An immune system that becomes ineffective in supp...

Topical treatment helps prevent actinic keratosis from developing into skin cancer
In this study, 624 patients with multiple actinic keratoses were randomized to treatment with one of the four aforementioned field-directed treatments.
The primary endpoint of the study was the percentage of patients who had at least 75% reduction in their number of actinic keratoses after one year. The study found that the percentage of patients who achieved this goal was significantly higher in people treated with topical fluorouracil (75%), compared to those treated with topical imiquimod (54%), photodynamic therapy (38%), and topical ingenol mebutate (29%).
This seminal study highlights the important role of field-dire...

In this study, we found that cofilin competes with tau for direct microtubule binding in vitro, in cells, and in vivo, which inhibits tau-induced microtubule assembly. Genetic reduction of cofilin mitigates tauopathy and synaptic defects in Tau-P301S mice and movement deficits in tau transgenic C. elegans. The pathogenic effects of cofilin are selectively mediated by activated cofilin, as active but not inactive cofilin selectively interacts with tubulin, destabilizes microtubules, and promotes tauopathy. These results therefore indicate that activated cofilin plays an essential intermediary role in neurotoxic signaling th...

A Conservative View of the Present State of Senolytic Development for Rejuvenation
Here, one of the leading researchers working on the biochemistry of senescent cells - and their relevance to aging - considers the state of development of senolytic therapies. These are treatments, largely small molecule drugs at this stage, but also including suicide gene therapies, immunotherapies, and more, that are capable of selectively destroying some fraction of the senescent cells present in old tissues. There is tremendous enthusiasm in the scientific and development communities for the potential to create significant degrees of rejuvenation via this approach. The results in mice are far and away more impressive a...

Keynote speech on the JAVELIN not going far enough to improve survival
The treatment landscape for metastatic renal-cell carcinoma has changed dramatically with the introduction of immunotherapies. Unfortunately though, we are promoting combinations over single agents without having much idea of added benefit of each drug. This is an important issue because when we combine two drugs, the only thing we are certain of are the added toxicities. PD-1 inhibitor nivolumab had improved OS when given in second line, however nivolumab was tested in combination with ipilimumab (not as a nivolumab monother...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an ass...

In this study, we report the age-associated differences between fetal MSC (fMSC) populations and MSCs isolated from elderly donors with respect to their transcriptomes. We successfully reprogrammed fMSCs (55 days post conception) and adult MSC (aMSC; 60-74 years) to iPSCs and, subsequently, generated the corresponding iMSCs. In addition, iMSCs were also derived from ESCs. The iMSCs were similar although not identical to primary MSCs. We unraveled a putative rejuvenation and aging gene expression signature. We show that iMSCs irrespective of donor age and cell type re-acquired a similar secretome to that of their parent...
