DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Researchers supplement synthetic biology toolkit to streamline investigations into genetic code expansion

One of modern biologists' most ambitious goals is to learn how to expand or otherwise modify the genetic code of life on Earth, in order to make new, artificial life forms.

Researchers find potential cure for a previously unknown childhood genetic condition

Describing a previously unknown genetic condition that affects children, researchers at University of California San Diego School of Medicine and Rady Children's Institute for Genomic Medicine say they also found a potential method to prevent the gene mutation by administering a drug during pregnancy.

Novel strategy for in vitro cell-selective protection has potential for use in adoptive cell therapy

Adoptive cell therapy (ACT) is an emerging powerful cancerimmunotherapy, which includes a complex process of genetic modification, stimulation and expansion. During invitroorexvivomanipulation, sensitive cells are inescapably subjected to harmful external stimuli. Although a variety ofcytoprotectionstrategies have been developed, their application on ACT remains challenging.

Methylation of TDP-43 DNA linked to age-dependent motor cortex involvement in ALS

Amyotrophic lateral sclerosis (ALS) is an intractable neurological disease. Aging is a risk factor for the accumulation of TDP-43 (transduction responsive region DNA-binding protein of 43kDa) in the motor cortex. TDP-43 is a protein that tends to accumulate in increasing amounts, and the amount is strictly controlled by the splicing of TDP-43. Through cell experiments and analysis of human brain tissue, researchers at Brain Research Institute, Niigata University, led by Akihiro Sugai, M.D., Ph.D., have found that methylation of TDP-43 DNA is involved in the background of motor cortex involvement with aging in ALS

Researchers compare transcriptomic and cytokine responses of colorectal cancer cells

Oncotarget published "Pan-drug and drug-specific mechanisms of 5-FU, irinotecan (CPT-11), oxaliplatin, and cisplatin identified by comparison of transcriptomic and cytokine responses of colorectal cancer cells" which reported that there was an increase in IL-8 by oxaliplatin and increase in ferritin by cisplatin which may contribute to cancer cell survival.

Aging may not be due to build-up of mutations alone, study suggests

New research exploring theories of ageing has found that small mutations accumulating in DNA are unlikely to be fully responsible for this process.

Supercoiling and looping can transmit mechanical stress along the DNA backbone, research shows

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are known to influence every aspect of DNA activity, but how this happens has not been clear.

Researchers create an integrated pipeline for performing genetic screening studies

Today's genetic engineers have a plethora of resources at their disposal: an ever-increasing number of massive datasets available online, highly precise gene editing tools like CRISPR, and cheap gene sequencing methods. But the proliferation of new technologies has not come with a clear roadmap to help researchers figure out which genes to target, which tools to use, and how to interpret their results. So, a team of scientists and engineers at Harvard's Wyss Institute for Biologically Inspired Engineering, Harvard Medical School (HMS), and the MIT Media Lab decided to make one.

Evidence of persisting autoreactivity in post-acute sequelae of SARS-CoV-2 infection?

It has been demonstrated in recent studies that there is a significant breadth of emerging autoreactivity associated with severe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. More specifically, researchers from Emory University have identified a relaxation of peripheral tolerance within early antibody secretion cells that arise in individuals infected with SARS-CoV-2, as important drivers of those responses.

Novel antibody candidate shows potent binding to diverse SARS-CoV-2 variant mutations

Twist Bioscience Corporation (Nasdaq: TWST) today reported that its internally-discovered antibody candidate TB202-3 (CoVIC-094), demonstrated potent binding to diverse SARS-CoV-2 variant mutations, including strains with the E484K, N501Y, D614G, Y453F and K417N mutations in pseudovirus assays, indicating this therapeutic antibody may be effective in treating many strains of COVID-19.

Researchers describe a novel role for hnRNP E1 protein in binding DNA in the nucleus

Cancer is a devastating disease and is the second leading cause of death in the U.S. One of the hallmarks of cancer is genomic instability, or the tendency to accumulate mutations and damage to the DNA that leads to genome alterations during cell division.
