Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells´ sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research. Researchers would to like see their laboratory findings — published in the journal´s Dec. 5 print edition — lead to safer, more effective combination therapies for hard-to-treat pediatric brain cancers like medulloblastoma and high-grade...

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that cancer cells tap into a natural recycling system to obtain the energy they need to keep dividing. In a study with potential implications for cancer treatments, Einstein researchers used genetic manipulation to turn off this recycling system within the walls of cells and stop both tumor growth and metastasis (cancer spread). The findings were published in today's online edition of Science...

Researchers at the RIKEN Brain Science Institute (BSI) have discovered a key mechanism responsible for selectively degrading aggregates of ubiquitinated proteins from the cell. Their findings indicate that the capture and removal of such aggregates is mediated by the phosphorylation of a protein called p62, opening the door to new avenues for treating neurodegenerative diseases such as Huntington's disease and Alzheimer's disease. One of the most important activities of a cell is the...

Scientists of the German Cancer Research Center have discovered an alternative mechanism for the extension of the telomere repeat sequence by DNA repair enzymes. The ends of the chromosomes, the telomeres, are repetitive DNA sequences that shorten every time a cell divides during the process of duplicating its genome. Once the telomeres become very short the cell stops dividing. Thus, telomeres work like a cellular clock that keeps an eye on the number of cell divisions. And once the...

How Chromosomes Find Each Other

[ Watch the Video ] After more than a century of study, mysteries still remain about the process of meiosis–a special type of cell division that helps insure genetic diversity in sexually-reproducing organisms. Now, researchers at Stowers Institute for Medical Research shed light on an early and critical step in meiosis. The research, to be published in the Nov. 8, 2011 issue of Current Biology, clarifies the role of key chromosomal regions called centromeres in the formation of a...

An international team of scientists, including biologists from the University of North Carolina at Chapel Hill, may have pinpointed for the first time the mechanism responsible for cell polyploidy, a state in which cells contain more than 2 paired sets of chromosomes. When it comes to human chromosomes and the genes they carry, our tissue cells prefer matched pairs. Bundled within the nucleus of our cells are 46 chromosomes, one set of 23 inherited from each of our parents. Thus, we are...

Understanding the endocycle has implications for agriculture and medicine An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass. This discovery, led by a geneticist at Fred Hutchinson Cancer Research Center and reported Oct. 30 in Nature, leads to a new...

Cell Cultures From A Machine
2011-10-28 11:01:58

Cell cultures form the basis of day-to-day research work in applications that range from the development of drugs and vaccines to the decoding of functions of individual genes. Up until now, cell cultures have been sown, tended, observed and transferred to vessels — all by hand. A new device automates these worksteps completely. The human genome has been decoded. Of all the puzzles it contains, though, many remain unsolved. We know that the genome provides the blueprint for various...
