Multiple changes in brain cells during embryonic development may contribute to schizophrenia

Multiple changes in brain cells during the first month of embryonic development may contribute to schizophrenia later in life, according to a new study by Weill Cornell Medicine investigators.

Identification of genetic variant provides a big step for precision medicine in dialysis

Every day, the human kidneys clean about 1,500 liters of blood by producing approximately 1–2 liters of urine. Thereby, the body gets rid of excess water and toxic waste products of the metabolism or also drugs and maintains the balance of water and minerals in the tissues.

Junk DNA' plays a crucial role in early embryonic development in all mammals, study shows

Nearly half of our DNA has been written off as junk, the discards of evolution: sidelined or broken genes, viruses that got stuck in our genome and were dismembered or silenced, none of it relevant to the human organism or human evolution.

Scientists analyze the molecular machinery of poxviruses at an atomic level

Poxviruses have found a unique way of translating their genes into proteins in the infected organism. A team of researchers from Würzburg shows for the first time how the molecular machinery involved works at an atomic level.

CRISPR-Cas9 system could help perform very effective target gene silencing

CRISPR-Cas9's extraordinary ability to modify specific areas of DNA has made it a favorite among gene-editing tools for researchers.

Exposure to even low levels of lead can trigger epigenetic changes

A research team from Brazil and Portugal has identified a link between a microRNA (miRNA) and the presence of lead in an organism.

Supercoiling characteristic of DNA's structure controls gene expression, research shows

The two meters of -stretched- DNA contained in human cells are continuously twisting and untwisting to give access to genetic information: when a gene is expressed to generate a protein, the two strands of DNA are separated to give access to all the machinery necessary for this expression, resulting in an excessive accumulation of coiling that needs to be resolved later.

New gene editing approach bypasses disease-causing mutations

A new approach to gene editing using the CRISPR/Cas9 system bypasses disease-causing mutations in a gene, enabling treatment of genetic diseases linked to a single gene, such as cystic fibrosis, certain types of sickle cell anemia, and other rare diseases.

Study reveals DNA supercoiling is involved in regulating gene expression

The (when stretched) two-meter-long DNA molecule in each human cell is continuously being unpacked and packed again to enable the expression of genetic information.

CSHL investigator aims to predict the effects of mutations on different tomato varieties

Both people and tomatoes come in different shapes and sizes. That is because every individual has a unique set of genetic variations--mutations--that affect how genes act and function. Added together, millions of small genetic variations make it hard to predict how a particular mutation will impact any individual.

New mechanism of transcriptional regulators influences tumor development

The Wistar Institute scientists have discovered a novel mechanism of transcriptional regulation of cellular senescence that promotes the release of inflammatory molecules that, in turn, affect tumor growth by changing the surrounding microenvironment.

Researchers use CRISPR to tinker with corn kernel numbers

Corn--or maize--has changed over thousands of years from weedy plants that make ears with less than a dozen kernels to the cobs packed with hundreds of juicy kernels that we see on farms today. Powerful DNA-editing techniques such as CRISPR can speed up that process.

Pioneer transcription factors help turn on key genes that give cells unique properties

Biologists have long wondered how complex organisms contain a variety of dramatically different types of cells with specialized functions, even though all of those cells are genetically identical.

New protocol identifies mismatch repair deficiency

Researchers have developed a new integrated genetic/epigenetic DNA-sequencing protocol known as MultiMMR that can identify the presence and cause of mismatch repair (MMR) deficiency in a single test from a small sample of DNA in the colon, endometrial, and other cancers.

New multidimensional model of trophoblast motility uses a functionalized hydrogel

Trophoblast cells, which surround the developing blastocyst in early pregnancy, play an important role in implantation in the uterine wall.

Innovative gene therapy approach for regeneration of functional new neurons

Spinal cord injury (SCI) often causes disability and seriously compromises quality of life. While decades of research have made significant progress in axonal regeneration after SCI, most of the interventions have not been translated into clinical therapies.

Study elucidates genes responsible for Glioblastoma invasiveness

One of the hallmarks of Glioblastoma (GBM), the most aggressive type of brain cancer, is its high invasive capacity, which leads to its expansion into the normal brain tissue.

Research reveals fundamental insights into the causes of severe birth defects

Research by Kai Jiao, M.D., Ph.D., and colleagues at the University of Alabama at Birmingham and in Germany has yielded fundamental insights into the causes of severe birth defects known as CHARGE syndrome cases. These congenital birth defects include severe and life-threatening heart malformations.

Gaining new insights into bacterial pneumonia

Jacqueline Kimmey speaks to AZoLifeSciences about her research into bacterial pneumonia and the genes that drive its spread from the lungs into the blood.

Myeloid cell can suppress the immune response to tumor cells

For a long time, researchers had believed that the brain reduces inflammation by protecting itself from an aggressive immune response.
