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).

Pioneering project on genomic edition through CRISPR/Cas9 to study early embryonic development

Characterization studies of early embryonic development are limited, mainly due to the lack of samples and the obvious legal and ethical limitations.

Finding a cure for canine gliomas may help find treatment for human brain cancer

Cancer research using experimental models--everything from cancer cells in a dish to patient tumors transplanted in mice--has been extremely useful for learning more about the disease and how we might treat it.

Study explores how some mammals postpone development of their embryos

How do some mammals postpone the development of their embryos to await better conditions for having offspring? A recent study at the UW Medicine Institute for Stem Cell and Regenerative Medicine explored this reproductive enigma, which can occur in more than 130 species of mammals as well as in some marsupials.

Depression treatment using AI, brain scans

Artificial intelligence (AI) may be a useful and even essential tool in selecting the best treatment for depression, according to a new study published in the journal Nature Biotechnology on February 2020.

Finding the origins of angiosarcoma

In a new study published in the journal Nature Medicine on February 2020, scientists report some newly discovered reasons for the occurrence of a rare blood vessel wall cancer called angiosarcoma. This could one day help develop better therapies for this aggressive tumor. The project is a striking example of unexpectedly rich findings from a crowd-sourced venture that brings together a scattered group of patients with a rare disease.

Higher maternal blood pressure linked to placental gene modifications

Higher maternal blood pressure in pregnancy is associated with chemical modifications to placental genes, according to a study by researchers from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, part of the National Institutes of Health.

Protein Data Bank archive releases new coronavirus protease structure

The Protein Data Bank archive, which contains more than 160,000 3D structures for proteins, DNA, and RNA, this month released a new Coronavirus protease structure following the recent coronavirus outbreak, an ongoing viral epidemic primarily affecting mainland China that now threatens to spread to populations in other parts of the world.

Growing eggs and sperm to treat infertility

Scientists at the University of California, Los Angeles, have reported, in the journal Cell Reports, the mechanism of how the very early precursor or stem cells which eventually give rise to the germ cells, eggs and sperm, are formed over the course of development. This could help create eggs and sperms under laboratory conditions to help infertile people who don’t have sperms, or eggs, for instance.

CRISPR-edited immune cells can be safely given to cancer patients

The emergence of CRISPR-Cas9 gene-editing technology has spurred hope in both doctors and patients since it shows promise in treating a multitude of diseases, including cancer. For the first time in the United States, a team of scientists has shown that CRISPR-edited immune cells can be safely used to cancer patients.

Genomic sequencing technique helps understand gut microbiota one cell at a time

A population of microorganisms living in our intestine, known as the gut microbiota, plays a crucial role in controlling our metabolism and reducing the risk of conditions such as obesity and diabetes.

Novel method to monitor residual disease after treatment in high-risk neuroblastoma patients

A research group led by Professor NISHIMURA Noriyuki (Graduate School of Health Sciences, Kobe University) has developed a new method to monitor the residual disease after treatment in high-risk neuroblastoma patients.

Research provides new insights into molecular basis of X-chromosome inactivation

Researchers at the European Molecular Biology Laboratory in Heidelberg and Institut Curie in Paris have shown that the protein SPEN plays a crucial role in the process of X-chromosome inactivation, whereby female mammalian embryos silence gene expression on one of their two X chromosomes.

Collaborative research uncovers underlying rules that, when broken, contribute to ALS

Clumps of proteins inside cells are a common thread in many neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease.

Coronavirus - pandemic or not?

The coronavirus strain called 2019-nCoV has been causing widespread illness in China, with 28,276 affected by the virus and over 565 deaths worldwide, mostly in China. As of now, it is already more deadly than the SARS epidemic that raged between 2002 and 2004.

CDC diagnostic coronavirus test gets FDA emergency approval

In the light of the ongoing novel coronavirus epidemic in China, the US Food and Drug Administration has granted approval of a diagnostic test for use in emergency situations (emergency use authorization or EUA). The viral infection has spread to many different and distant parts of the world, involving over 25,000 people and causing nearly 600 deaths since it started in December 2019.

Largest genome study sheds light on how genetic glitches trigger tumor formation

It is well-known that when a gene mutates, it triggers tumor formation by stimulating abnormal cell growth and proliferation. Cancer starts from a mutant gene that kickstarts a series of abnormal growth, forming a tumor. However, the exact mechanism of how this happens remains unclear.

Genetic fingerprints could help identify cancer-causing culprits

Causes of cancer are being cataloged through an international study revealing the genetic fingerprints of DNA-damaging processes that drive cancer development.

Natural antioxidant reverses reproductive harms caused by BPA exposure in worms

From plastics to pesticides, it seems like every week delivers fresh news about the dangers of endocrine disruptors--chemicals in the environment that alter the body's hormones and can lead to reproductive, developmental, neurologic and immune problems and cancer.
