Kidney cancer study provides new insights into tumor invasion and metastatic competence

How cancers metastasize remains poorly understood. The process begins when cancer cells break off from a tumor and invade blood and lymphatic vessels, the body's alleyways. But studying invasion - typically a microscopic process - is challenging.

Researchers develop a new method to remove old cells from tissues to slow down aging

No one knows why some people age worse than others and develop diseases -such as Alzheimer's, fibrosis, type 2 diabetes or some types of cancer- associated with this ageing process.

Study offers clues to why calorie-restricted diet may slow tumor growth

In recent years, there has been some evidence that dietary interventions can help to slow the growth of tumors.

Washington University receives $7.5 million to support NIH's research on senescent cells

Washington University School of Medicine in St. Louis is joining the National Institutes of Health's new research network focused on the study of senescent cells, a rare and important population of cells that is difficult to study but vital for understanding aging and the diseases of aging, including cancer and neurodegeneration.

NIH launches new program to identify and characterize the differences in senescent cells

The National Institutes of Health has launched a program to study a rare type of cells, called "senescent" cells, that play both positive and negative roles in biological processes.

Understanding how brain cells talk could help find new treatments for neurological, psychiatric conditions

Experts from the University of Nottingham have discovered that reversing the modification of molecular messages at synapses in the human brain, may contribute to reversible mental health conditions such as anxiety, and memory diseases such as dementia.

Tau reduction impacts brain cells involved in creating abnormal activity

With the school year well on its way, we all recognize the importance of getting students energized. However, we also know that overstimulated children can wreak havoc on a classroom, leaving a teacher trying to regain control of their group. The situation is very similar in the brain, where cells must remain active-;but in an orderly manner-;to carry out their many important tasks.

Study highlights the critical role of junk DNA in mammalian development

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.

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.

Immune system activation is modulated according to the time of day

Circadian clocks, which regulate most of the physiological processes of living beings over a rhythm of about 24 hours, are one of the most fundamental biological mechanisms.

Researchers use game theory to understand how cells compete in tumors

Game theory applied to cell encounters inside a tumor provides a sociological perspective on the possible behaviors of cells in a collectivity, and offers a more comprehensive understanding of the complex rules that govern a neoplasm.

Research reveals new role of immune cells that protect the brain from disease and injury

University of Virginia School of Medicine researchers have revealed a vital but previously unknown role for immune cells that protect the brain from disease and injury: The cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels.
