Oncotarget: cGAS-STING pathway in oncogenesis and cancer therapeutics
October 20, 2020
(Impact Journals LLC) Oncotarget Volume 11, Issue 30 reported that recent evidence shows that the host innate immunity is also critical in sensing the presence of cytoplasmic DNA derived from genomic instability events, such as DNA damage and defective cell cycle progression.
Eureka Alert
October 20, 2020
(Impact Journals LLC) Oncotarget Volume 11, Issue 30 reported that genomic profiling of murine mammary tumor cells with differential VDR expression identified 35 transcripts that were altered by the 1,25D3-VDR complex including Hyaluronan Synthase-2.
Fight Aging!
October 19, 2020
Age-related changes to the microbial populations of the gut, the gut microbiome, appear important in the progression of aging. The effects on long-term health and risk of age-related conditions might be on a par with those of physical activity, and certainly overlap with those of diet. With ageing, beneficial microbes that produce metabolites (such as...
Molecules Leaking from Damaged Muscle Fibers can Activate Muscle Stem Cells
October 19, 2020
Declining muscle stem cell function appears likely to be the most important contributing cause of sarcopenia, the characteristic loss of muscle mass and strength with age. Studies of the stem populations that support muscle tissue have suggested that the cells are largely intact and capable, but quiescent. This may be a reaction to changes in...
Targeting NAD+ Metabolism for the Treatment of Cardiovascular Disease
October 19, 2020
Nicotinamide adenine dinucleotide (NAD+) is important to mitochondrial function, the supply of chemical energy store molecules to power cellular processes, and thus to cell and tissue function. Levels of NAD+ decline with age, a part of the deterioration of mitochondrial function throughout the body:. Too little NAD+ is created, too little NAD+ is recycled after...
Eureka Alert
October 19, 2020
(Oregon Health & Science University) Analysis of nearly 2.5 million Medicare-funded hospitalizations near the end of a patient's life found the use of non-invasive ventilation has increased substantially, even though there is little data to support its use in certain patient groups, such as those with cancer and dementia near the end of life.
