Study unearths previously unknown role of CTCF, the transcription regulator

Researchers discovered evidence that CTCF governs chromatin accessibility, the mechanism of opening tightly spooled DNA facilitating gene expression.

Study reveals mechanisms promoting overall glioma tumor growth

Researchers from Northwestern Medicine unearthed the epigenetic processes involved in the regulation of multiple oncogenes in glioma cells.

New technique can map out nearly all of the regulatory switches across a maize genome

Getting a full understanding of how genes are regulated is a major goal of scientists worldwide. Now, a Florida State University professor and his research partners have developed a technique that can map out nearly all of the likely regulatory switches across a genome.

Research provides a detailed 'proteogenomic' view of lung squamous cell carcinoma

Lung cancer remains the leading cause of cancer-associated death in the United States and worldwide. Patients with a subtype called lung adenocarcinoma (LUAD) have benefited from the development of new targeted medicines, but the search for effective new therapies for another subtype called lung squamous cell carcinoma (LSCC) has largely come up short.

Study on protein complex could help support cancer prevention efforts, drug development

Researchers have used sophisticated imaging technology to offer unmatched insights into the BRCA1-BARD1 protein complex.

Study reveals the role of transcription in shaping the genome

Developments in the field of microscopy allowed scientists to picture loops of DNA strands for the first time.

Study shows that inactivation of BRG1 leads to high genetic instability

Following the p53 tumor suppressor gene, the genes encoding two proteins of the SWI/SNF chromatin remodeling complex are the most often identified mutated.

Cancer cells re-organize DNA structure to ramp up the activity of oncogenes

A lot of biological mechanisms go wrong in cancer—for example genes mutate and cells proliferate in an uncontrollable manner.

Researchers study the unique genomic organization of coral symbionts

According to recent findings, the genome of single-celled plankton, called dinoflagellates, is arranged in an extremely unusual and strange manner. The study results set the foundations for further research into these vital aquatic species and significantly broaden the understanding of what a eukaryotic genome can look like.

New integrative genetic screening technology offers insights into role of DNA accessibility in cancer

In a new resource for the scientific community, published today in Nature Biotechnology, researchers in the lab of Neville Sanjana, PhD, at the New York Genome Center (NYGC) and New York University (NYU) developed CRISPR-sciATAC, a novel integrative genetic screening platform that jointly captures CRISPR gene perturbations and single-cell chromatin accessibility genome-wide.

Natural molecule can effectively block the binding of human antibodies to SARS-CoV-2

Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

DNAJC9 protein plays a key role in protecting histones in the cell nucleus

Histones play an important role in the cell nucleus by packaging DNA into chromatin.

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.

Study reveals key process by which plants switch between different stress responses

To design effective strategies that protect significant agricultural crops from climate change, it is important to understand how plants react to stressful environmental conditions.

3D genome study reveals molecular regulatory mechanisms of human brain evolution

A team led by Prof. SU Bing from the Kunming Institute of Zoology (KIZ) of the Chinese Academy of Sciences (CAS), Prof. LI Cheng from Peking University, and Prof. ZHANG Shihua from the Academy of Mathematics and Systems Science of CAS has reported the highest resolution by far of the 3D genome of the primate brain, and demonstrated the molecular regulatory mechanisms of human brain evolution through cross-species multi-omics analysis and experimental validation. The study was published in Cell.

LEAFY protein licenses cell reprogramming to floral fate

Cells don't express all the genes they contain all the time. The portion of our genome that encodes eye color, for example, doesn't need to be turned on in liver cells. In plants, genes encoding the structure of a flower can be turned off in cells that will form a leaf.

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.

Researchers use heat map data to reverse engineer chromosome models

Genome analysis can provide information on genes and their location on a strand of DNA, but such analysis reveals little about their spatial location in relation to one another within chromosomes -- the highly complex, three-dimensional structures that hold genetic information.

Study reveals richness of space-time gene expression dynamics of the liver

Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".
