Lamin C important for keeping cell’s genetic material organized, research shows

In a study with lab-grown mouse cells, Johns Hopkins Medicine researchers say they have found that a protein that helps form a structural network under the surface of the cell's "command center" — its nucleus — is key to ensuring that DNA inside it remains orderly.

Study highlights the need for caution while using CRISPR-based gene therapies

A comprehensive study-;conducted by researchers at Sanford Burnham Prebys, the National Cancer Institute (NCI) and other groups-;has shown that gene editing, specifically gene knockout (KO), with CRISPR -Cas9 can favor cells with mutated forms of genes linked to cancer.

Scientists discover key component of cellular malfunction that contributes to growth of tumors

Scientists have homed in on a crucial step within the sequence of chemical reactions that govern regulation of cell division, proliferation and death, and whose malfunction contributes to the growth of tumors.

Protein plays a previously unknown role in halting cell cycle in response to stressful conditions

UT Southwestern researchers have identified a new mechanism by which stress causes cells to stop dividing.

Researchers identify mechanism behind insufficient treatment efficacy of psoriasis drugs

Interleukin-12 - a messenger molecule of immune cells - was long considered to trigger the development of psoriasis.

Researchers discover how Staphylococcus aureus protects itself against important antibiotic

The skin bacterium Staphylococcus aureus often develops antibiotic resistance. It can then cause infections that are difficult to treat.

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.

Researchers discover a new paradigm for how biological switches are regulated

Quantitative Biosciences Institute (QBI) researchers at UC San Francisco have discovered a new paradigm for how fundamental biological switches, proteins that can be turned on and off to control processes like cell differentiation, cell growth, and transport within a cell, are regulated at the molecular level, specifically by molecules binding at newly discovered sites far away from the main binding site, and the broader impacts these changes have on a cellular level.

New method helps to analyze proteins during dynamic processes on biological membranes

A large proportion of biologically relevant processes take place at membranes. Studying the dynamics of these processes in real time and without disturbing the biological system is still a major methodological challenge.

CRISPR/Cas9-directed epigenetic editing reveals diverse transcriptomic regulation and functional effects

Oncotarget published "Diverse transcriptional regulation and functional effects revealed by CRISPR/Cas9-directed epigenetic editing" which reported that the adequate functioning of this process is indispensable for tissue homeostasis and cell fate determination.

Researchers discover how a genetic mutation in mice and monkeys interferes with viruses

A nationwide team of researchers, led by scientists at University of Utah Health and The Rockefeller University, has determined how a genetic mutation found in mice and monkeys interferes with viruses such as HIV and Ebola.

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.

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.

Novel anti-hormonal therapy may be a new treatment option for early-stage breast cancer

Early results from a UCLA-led clinical trial found treating women with estrogen receptor (ER)-positive and human epidermal growth factor receptor-2 (HER2)-negative early breast cancers with a novel type of anti-hormonal therapy, called an oral selective estrogen receptor degrader (SERD), led to clinically meaningful reductions in tumor activity prior to surgery.

Novel cell reprogramming offers a promising therapeutic strategy to slow down glioblastomas

Gliomas are the most common primary brain tumors in adults. Among them, high-grade glioblastomas (GBMs) are particularly known to be notoriously aggressive and invasive, which makes it challenging to treat them. The disease rapidly progresses to an advanced stage in a short span of time, and the survival of such patients is often dismal.

Results from Phase 0/1 trial of ribociclib plus everolimus in patients with high-grade glioma announced

The Ivy Brain Tumor Center at Barrow Neurological Institute, the largest early-phase drug development program for brain cancer in the world, announced results from their Phase 0/1 clinical trial of ribociclib plus everolimus in patients with high-grade glioma (HGG).

Temperature variations could have driven the division of protocells

A simple mechanism could underlie the growth and self-replication of protocells-;putative ancestors of modern living cells-;suggests a study publishing September 3 in Biophysical Journal.

Researchers show how a protein molecular motor can 'constrict' cell membranes

Cells in the human body constantly receive substances from the outside via a process called endocytosis. One important endocytosis pathway involves the formation of a protrusion within the cell membrane, pointing to the inside of the cell, triggered when a molecule needing to get in reaches the membrane.

Mystery of roe deer embryonic diapause revealed

Everyone is familiar with the roe deer, either from crossword puzzles or from real-life encounters during a jog or a hike in the forest: majestic creatures with elegant big black eyes.
