Cancer cells can exchange and recombine their genetic material, shows study

Evolution within groups of tumor cells follows the principles of natural selection, as evolution in pathogenic microbes.

Speciation process takes place in the presence of maximal gene flow, indicates study

Spatial isolation is known to promote speciation - but researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.

Study addresses mystery of how chromosomes are inherited during cell division

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.

Scientists show how plants adapt root growth to varying sources of nitrogen

Nitrogen is one of the most essential nutrients for plants. Its availability in the soil plays a major role in plant growth and development, thereby affecting agricultural productivity.

Researchers identify a vital protein needed to regulate anti-tumor immune response

Scientists from The University of Texas MD Anderson Cancer Center have identified a protein known as NF-kappa B-inducing kinase (NIK).

Study reveals evolutionary relationship between two different organelles in liverwort cells

Cells, the basic unit of life, are surrounded by a limiting membrane called the plasma membrane. Inside cells, there are various membrane-bounded organelles, each of which has various and distinctive functions.

Scientists discover molecular defects associated with rare genetic disorder in children

Damien D'Amours and his team at the Ottawa Institute of Systems Biology needed three years to discover the molecular defects associated with the LIC Syndrome, a serious genetic disorder that affects young children and result in acute respiratory distress, immune deficiency and abnormal chromosomes.

New computational tool can segment and analyze cell images of C. elegans

A joint research team co-led by City University of Hong Kong (CityU) has developed a novel computational tool that can reconstruct and visualise three-dimensional (3D) shapes and temporal changes of cells, speeding up the analysing process from hundreds of hours by hand to a few hours by the computer.

New method could help resolve unwanted genetic changes associated with CRISPR-Cas9 technique

A research team has used a novel method that could help resolve the issue of unnecessary genetic changes encountered in the CRISPR-Cas9 technique.

Study confirms that telomere shortening helps prevent cancer in humans

As time goes by, the tips of your chromosomes--called telomeres--become shorter. This process has long been viewed as an unwanted side-effect of aging, but a recent study shows it is in fact good for you.

Study shows how telomeres protect chromosome ends

Telomeres are essentially specialized structures that are located at the end of chromosomes. These structures ensure a healthy cell division.

Researchers use new technique to visualize the world of lipid dynamics

The potential to “see” the inner mechanisms of structures provides the promise of developments in the diagnosis and treatment of various diseases.

Researchers explain how tissue tension influences the orientation of cell division

The human body experiences many cell divisions during a lifetime. Such a biological process is crucial to form and sustain organs and tissues inside the body.

Low levels of hydrogen peroxide can slow down cell aging

High levels of reactive oxygen species, called oxidants, are detrimental to cells in all organisms and have been associated with ageing.

Scientists discover new anti-cancer molecule

A group of Moscow scientists has discovered and explained the activity mechanism of a new anti-cancer molecule -- diphenylisoxazole. This molecule has been shown to be effective against human cancer cells. The research, published in the journal Bioorganic & Medicinal Chemistry Letters, makes it possible to produce an affordable cancer treatment drug.

Researchers identify a promising target for treating chemo-resistant cancer cells

As medical professionals and scientists work to design new therapies for cancer, they come across a range of difficulties.

Components leaking from broken muscle fibers activate 'satellite' muscle stem cells

While building a muscle damage model in a cultured system, a research collaboration between Kumamoto University and Nagasaki University in Japan has found that components leaking from broken muscle fibers activate "satellite" muscle stem cells.

Scientists discern molecular mechanisms underlying plant parasitism and cross-species grafting

Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena.

Proteins act as compasses to guide stem cell division in plants

The stem cells tasked with creating and maintaining biological tissues have a difficult job. They have to precisely divide to form new specialized cells, which are destined to different fates even though they contain identical DNA. An obvious question then is: How do the cells divide in all the right ways to produce a healthy tissue?

New study unravels genetic vulnerability in breast cancer tumors

A new study has unraveled a genetic vulnerability that exists in almost 10% of all breast cancer tumors.
