Non-coding RNA plays a key role in regulating behavior of chromosome loops and gene expression

An important player in the healthy development of female embryos turns out also to play a key role in regulating the behavior of chromosome loops and gene expression in both sexes, according to a new study by researchers at Massachusetts General Hospital.

MIT scientists discover how molecular clusters interact with chromosomes in the nucleus

A cell stores all of its genetic material in its nucleus, in the form of chromosomes, but that's not all that's tucked away in there. The nucleus is also home to small bodies called nucleoli - clusters of proteins and RNA that help build ribosomes.

The antiviral function of BET protein against SARS-CoV-2 infection

Considering the past shreds of evidence on BRD2 and BRD4 associated with viral infections, researchers have recently evaluated the function of all relevant BET proteins during COVID-19 infection.

Researchers reveal the mechanism of artificial chromosome formation in C. elegans' embryos

A research team led by Dr Karen Wing Yee YUEN, Associate Professor from the School of Biological Sciences at the University of Hong Kong (HKU), revealed the mechanism of artificial chromosome (AC) formation in the embryos of the model organism Caenorhabditis elegans, a 1-mm long, transparent nematode.

Impact of BRCA1 mRNA expression on survival of patients breast and colorectal cancer

Oncotarget published "Opposing effects of BRCA1 mRNA expression on patient survival in breast and colorectal cancer and variations among African American, Asian, and younger patients" which reported that LMNB2 is a chromatin remodeling protein that also plays a role in eukaryotic cell proliferation by organizing the nuclear membrane during mitosis.

New algorithm provides a high-definition analysis of genome organization in single cells

Within the microscopic boundaries of a single human cell, the intricate folds and arrangements of protein and DNA bundles dictate a person's fate: which genes are expressed, which are suppressed, and - importantly - whether they stay healthy or develop disease.

NIH awards more than $8 million to support seven high-risk, high-reward projects at Penn Medicine

The National Institutes of Health has awarded grants to researchers in the Perelman School of Medicine at the University of Pennsylvania to support "highly innovative and broadly impactful" biomedical science through the NIH Common Fund's High-Risk, High-Reward Research program. The seven awards total approximately $8.2 million over five years,

Characterization of circulating neutrophils from hospitalized COVID-19 patients

A new preprint deals with the characterization of neutrophil phenotypes in an attempt to provide biomarkers that can predict severe disease in patients hospitalized with COVID-19.

Mouse brain atlas may help understand the complex circuits of the human brain

The circuits of the human brain contain more than 100 billion neurons, each linked to many other neurons via thousands of synaptic connections, resulting in a three-pound organ that is profoundly more complex than the sum of its innumerable parts.

Neuroscientists unveil detailed atlas of brain cells

When you clicked to read this story, a band of cells across the top of your brain sent signals down your spine and out to your hand to tell the muscles in your index finger to press down with just the right amount of pressure to activate your mouse or track pad.

Study identifies specific small RNA molecule that can reduce levels of cancer-promoting gene

In a recent study published in CANCER RESEARCH , a team led by researchers at Tokyo Medical and Dental University (TMDU) identified a specific small RNA molecule, called a microRNA (miRNA or miR), that has the potential to be used as an anti-cancer therapeutic.

Study provides novel insights into how KLF4 influences gene expression

A team led by researchers at Baylor College of Medicine has discovered a mechanism by which transcription factor KLF4 can help to organize chromatin, thus influencing gene expression.

Repeated injury to the epithelial tissue of airways causes "biological aging" of stem cells

Are prematurely aged or overworked stem cells a significant factor in chronic lung disease? Findings of a study just released in STEM CELLS Translational Medicine (SCTM) say this is likely so.

Scientists use statistical mechanics to make sense of DNA folding

At more than 2 meters long, the human DNA molecule uses intricate folding patterns to fit into cells while locally unfolding to express genes. Such phenomena, however, are difficult to measure in experiments, and theoretical frameworks explaining them continue to be at odds with one another.

Fountain of youth for the epigenome could become important in the treatment of osteoporosis

As we age, our bones become thinner, we suffer fractures more often, and bone-diseases such as osteoporosis are more likely to occur. One responsible mechanism involves the impaired function of the bone-marrow stem cells, which are required for the maintenance of bone integrity.
