Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Turning back the clock on aging immune systems: New treatment rejuvenates elderly defenses

Study demonstrated that selectively reducing myeloid-biased hematopoietic stem cells (my-HSCs) in aged mice rejuvenated the immune system, enhanced lymphopoiesis, reduced inflammation, and improved responses to viral infection, highlighting a potential strategy for countering age-related immune decline.

Heart at risk from ARDS: Inflammatory responses fuel cardiovascular complications

Research highlights the inflammatory impacts of ARDS on the heart, underscoring the role of immune responses in cardiovascular complications from viral infections, including COVID-19, and emphasizes the potential of TNF-α neutralizing therapy to mitigate these effects.

Study shows cellular, molecular overlaps in ALS and FTLD

On the surface, the movement disorder amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, and the cognitive disorder frontotemporal lobar degeneration (FTLD), which underlies frontotemporal dementia, manifest in very different ways. In addition, they are known to primarily affect very different regions of the brain.

Aging linked to length of genes, study suggests

Aging may be less about specific "aging genes" and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers in an opinion piece publishing March 21 in the journal Trends in Genetics.

Scientists uncover four proteins that govern the identity of anaplastic large cell lymphoma

A collaboration between scientists from St. Jude Children's Research Hospital and Dana-Farber Cancer Institute uncovered four proteins that govern the identity of anaplastic large cell lymphoma (ALCL), an aggressive form of cancer.
