Endothelial Deletion of Wt1 Gene During Coronary Vessel Formation Affects Embryonic Heart Development

How is the mammals' heart formed? What role do endothelial cells play? Do the same pathways and genes involved in the formation of the embryonic heart also play a role in repair processes?

Study expands understanding of PAK1-related IDDMSSD

A recent study from Texas Children's Hospital and Baylor College of Medicine has expanded the clinical spectrum of a new epileptic disorder called Intellectual Developmental Disorder with Macrocephaly, Seizures, and Speech Delay (IDDMSSD) with the identification of the first recurrently affected residue identified in the protein kinase domain of PAK1 protein.

Identifying the underlying causes of rare genetic immune disorders

The activated PI3K Delta syndrome 2 (APDS2) is a rare genetic disease that is caused by cellular anomalies, according to experts from the Garvan Institute of Medical Research.

Study discovers the ability of certain blood immune cells to proliferate

The ability of a cell to divide, to proliferate, is essential for life and gives rise to the formation of complex organisms from a single cell.

Researchers find methods to awaken and revive neural stem cells

Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood. A team led by scientists from the Universities of Geneva (UNIGE) and Lausanne (UNIL) has discovered the importance of cell metabolism in this process and identified how to wake up these neural stem cells and reactivate them. Biologists succeeded in increasing the number of new neurons in the brain of adult and even elderly mice. These results, promising for the treatment of neurodegenerative diseases, are to be discovered in the journal Science Advances.

Role of probiotics and functional materials in the treatment of intestinal inflammation

Maintenance of sulfomucin is a key end point in the treatment of diarrhea and inflammatory bowel disease (IBD). However, the mechanism underlying the microbial sense to sulfomucin are poorly understood, and to date, there are no therapies targeting the secretion and maturation of sulfomucin in IBD. Considering the important role of gut microbiota in host immune regulation, maintain sulfomucin by modulating the gut microbiota is inspired.

Study reveals the mechanisms that prevent effective cancer cell death

Cancer is a disease driven by gene mutations. These mutated genes in cancer fall into two major categories: tumor suppressors and oncogenes. Mutations in tumor suppressor genes can allow tumors to grow unchecked – a case of no brakes – while mutations in oncogenes can activate cell proliferation, pushing the gas pedal all the way to the floor.

A treatment strategy to hasten cancer cell death

Gene mutations are the cause of cancer. Tumor suppressors and oncogenes are the two main groups of these altered genes in cancer. Mutations in oncogenes can drive cell proliferation, pushing the gas pedal to the floor, whereas mutations in tumor suppressor genes can cause tumors to grow unchecked—a situation in which there is no control.

Researchers report the genome-wide atlas of chromatin-accessibility during stomatal development

Researchers at Nagoya University in Japan, the University of Texas at Austin, and the University of Washington have elucidated a mechanism that makes tiny plant stem cells destined to give rise to stomata, cellular valves of plants that facilitate global carbon cycles.

Elaborating three-dimensional coordination of cell-division site positioning in a cyanobacterium

Cyanobacteria are considered to be the earliest oxygenic photosynthetic organisms present on Earth, and they have played crucial roles in the progress of the environment and life on the planet. Today, cyanobacteria are still found extravagantly in several ecological niches.

Exploring how plants can adapt to accelerating aridity due to climate change

At a time when climate change is making many areas of the planet hotter and drier, it's sobering to think that deserts are relatively new biomes that have grown considerably over the past 30 million years.

Deletion of p16Ink4a cells does not negatively impact β-cell mass and proliferation in mice

A new research paper was published on the cover of Aging (listed as "Aging (Albany NY)" by Medline/PubMed and "Aging-US" by Web of Science) Volume 15, Issue 2, entitled, "Clearance of p16Ink4a-positive cells in a mouse transgenic model does not change β-cell mass and has limited effects on their proliferative capacity."

Deep learning model can accurately predict the growth of deadly brain tumors

Researchers at the University of Waterloo have created a computational model to predict the growth of deadly brain tumors more accurately.

Molecular staple: The DNA repair mechanism impeding cancer treatment

Due to the continuous cellular activity, malfunctions frequently occur, making error-correcting systems crucial for cells. However, it serves the cancer cells’ best interests to cause errors when it comes to destroying them.

Role of clonal hematopoiesis as a broad driver of atherosclerosis

A group at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), collaborating with institutions in the USA, has shown that acquired mutations in the gene encoding the protein p53 contribute to the onset of atherosclerotic cardiovascular disease.

Researchers expand the known defensive abilities of CRISPR–Cas systems

Viruses can infect bacteria and archaea, just as they can humans. These microbes have evolved their own immune defense mechanisms to combat their pathogens. Bacterial defenses, like CRISPR-Cas systems, contain a variety of proteins and functions that aid bacteria in protecting themselves from foreign intruders.

Improving cancer immunotherapies with bioengineered synthetic gene circuits

In two distinct studies, scientists show how synthetic biology can be used to address a challenging problem in cancer immunotherapy: the way immunotherapy-related approaches focused on the short-term killing of tumor cells could fail to eradicate tumors because tumor growth occurs on longer timescales.

RXR: A key protein in the balanced production of different blood cells

In the regulation of hematopoietic stem cells—which are the immature stem cells that produce all the blood cell lineages—the cell protein retinoid X receptor (RXR) is an important element.

NIH funds research on mRNA vaccines to stop cancer development

The National Cancer Institute at the National Institutes of Health has awarded a multidisciplinary team of Weill Cornell Medicine researchers a five-year $5.7 million grant to support a center dedicated to creating messenger RNA (mRNA) vaccines to prevent the development of cancer in at-risk groups.
