mRNA Vaccines: From Tackling A Pandemic To Treating Cancer
The story of the multi-decade uphill battle Katalin Karikó and her fellow researchers fought to prove messenger RNA can viably be used in medicine is widely known today. In just as little as two years, the world has learned about mRNA technology and how fast it can react when the need arises holding almost unlimited promises in future applications. As always is the case with “instant hits” in science, the ride was actually very long and bumpy, but more on that later.
What is mRNA?
In very simple terms: messenger ribonucleic acids (or mRNAs in short) are the body’s natural way to transport messages from o...

In conclusion, long-term cumulative BP was associated with subsequent cognitive decline, dementia risk, and all-cause mortality in cognitively healthy adults aged ≥50 years. Efforts are required to control long-term systolic BP and pulse pressure and to maintain adequate diastolic BP.

Cancer Correlates with Increased Risk of Later Onset of Type 2 Diabetes
Researchers here note a correlation between cancer diagnosis and greater risk of later onset of type 2 diabetes. A reasonable guess is that this is mediated by the increased burden of cellular senescence produced by chemotherapy and radiotherapy, though, as the researchers point out, the widely different risks by cancer type may indicate that tumors are metabolically active in ways that specifically promote the metabolic dysfunction that leads to type 2 diabetes.
For patients with cancer, prevalent type 2 diabetes at the date of cancer diagnosis is associated with increased cancer-specific and all-cause mortality....

Natural Killer Cells Oppose In Vivo Reprogramming
We report that natural killer (NK) cells significantly limit reprogramming, both in vitro and in vivo. Cells and tissues in the intermediate states of reprogramming upregulate the expression of NK-activating ligands, such as MULT1 and ICAM1. NK cells recognize and kill partially reprogrammed cells in a degranulation-dependent manner. Importantly, in vivo partial reprogramming is strongly reduced by adoptive transfer of NK cells, whereas it is significantly increased by their depletion. Notably, in the absence of NK cells, the pancreatic organoids derived from OSKM-expressing mice are remarkably large, suggesting that ablat...

In conclusion, our results suggest that SAH extends lifespan by inducing MetR or mimicking its downstream effects. Since the lifespan-extending effects of SAH are conserved in yeast and nematodes, and MetR extends the lifespan of many species, exposure to SAH is expected to have multiple benefits across evolutionary boundaries. Our findings offer the enticing possibility that in humans the benefits of a MetR diet can be achieved by promoting Met reduction with SAH. The use of endogenous metabolites, such as SAH, is considered safer than drugs and other substances, suggesting that it may be one of the most feasible ways to ...

Bacteria Promote Cancer Metastasis
Given the onset of a particular type of cancer, why does that cancer become a much worse prospect for only some individuals? Why are some people more prone to metastasis, for example? A perhaps underappreciated factor is the interaction of infectious agents with the tumor microenvironment, as researchers discuss here. Exposure to pathogens, and particularly persistent pathogens, may be a good explanation for many areas of medicine in which only some people bearing all of the traditional risk factors go on to develop the worst outcomes.
Microbes play a critical role in affecting cancer susceptibility and tumor prog...

This study tests the feasibility of chronically elevating skeletal muscle NAD+ in mice and investigates the putative effects on mitochondrial respiratory capacity, insulin sensitivity, and gene expression. The metabolic effects of NR and PT treatment were modest. We conclude that the chronic elevation of skeletal muscle NAD+ by the intravenous injection of NR is possible but does not affect muscle respiratory capacity or insulin sensitivity in either sedentary or physically active mice. Our data have implications for NAD+ precursor supplementation regimens.

Muscle Strengthening Activities in Later Life Correlate with Reduced Mortality
Past studies have demonstrated reduced mortality as a result of strength training in older individuals. Muscle tissue is metabolically active, involved in a range of processes in the body, such as insulin metabolism and control of inflammation. Here this review paper, researchers note the correlation between activities that strengthen muscle and lower mortality in epidemiological data. It is worth thinking about for those of us tempted to let the exercise schedule lapse as life moves on.
Physical inactivity is a global public health problem. Regular engagement in muscle-strengthening activities (eg, resistance tra...

Short In Vivo Reprogramming Treatment Reverses Age-Related Omics Changes in Mice
Researchers here demonstrate that, in mice, many biological markers of aging (in the epigenome, transcriptome, and metabolome) are made more youthful by a short in vivo exposure to the Yamanaka factors capable of reprogramming cells into induced pluripotent stem cells. That process also resets epigenetic marks on the genome to a youthful configuration, improving mitochondrial function, among other benefits. In this case, the goal of a short treatment is to minimize any possible cell conversion, keeping the reprogramming exposure short enough to only change epigenetic markers, gene expression, and cell behavior to be more y...

In this study, they found these drugs can kill senescent cells from cultures of human fat tissue. The tissue was donated by individuals with obesity who were known to have metabolic troubles. Without treatment, the human fat tissues induced metabolic problems in immune-deficient mice. After treatment with dasatinib and quercetin, the harmful effects of the fat tissue were almost eliminated.

How MRI-guided radiation therapy is changing the paradigm in pancreatic cancer
I truly believe we ’re at the beginning of something great in terms of fundamentally changing how we approach pancreatic cancer, the third leading cause of cancer death in the United States. With a mortality rate of roughly 80 percent, it’s been referred to as a medical emergency, yet minimal progress has been mad e in itsRead more …How MRI-guided radiation therapy is changing the paradigm in pancreatic cancer originally appeared inKevinMD.com.
