Amyotrophic lateral sclerosis (ALS) only affects a fraction of cells and must be treated with high specificity. Scientists have achieved that by targeting mRNA sites associated with the disease [1]. Cryptic behavior ALS is a neurodegenerative disease in which age is a major factor. While it can be diagnosed at almost any age, the average...

In Aging Cell, researchers have published a potential method of ameliorating disc degeneration that focuses on the cells living in a low-oxygen environment within the discs. Living on low oxygen Yesterday, we discussed how an antioxidant compound was found to alleviate intervertebral disk degeneration (IVDD). This related paper focuses on a tissue that is already...

In Nature Genetics, researchers have described how a defect in RNA transcription constitutes a previously undiscovered mechanism of aging. When the blueprint becomes harder to read Gene expression begins when a cell transcribes RNA from DNA protein codes. This process, like almost all others, is affected by aging. One key reason behind this is, of...

A paper published in Aging explains the relationship of long noncoding RNAs, which change with aging, to age-related macular degeneration (AMD). A disease of deposits and aging This paper begins with a discussion of AMD and its prevalence. AMD is the most common cause of vision loss in people over 70 years old [1]. Its...

A paper published in Aging goes into detail about the proteins and RNA pieces that increase and decrease with aging, suggesting a multiple-clock approach to biomarkers. Blood proteins change with age The researchers start out by discussing existing clocks based on such measurements as imaging [1] and epigenetic methylation [2], which is the most well-known...

Scientists from Duke University have found a way to make adult fibroblasts differentiate into cardiomyocytes, which might help develop better heart attack treatments [1]. The imperfect repair HeartThe heart is a four-chambered organ located between our lungs. Blood is pumped by the heart through two loops, one to the lungs, oxygenating the blood, and the...
