Acceleration of cell cycle transition kinetic can make human blood stem cells more powerful

For the first time, the research group of Prof. Claudia Waskow at the Carl Gustav Carus Faculty of Medicine at Dresden Technical University is now describing a new mechanism in which the length of the G1 phase of the cell cycle has a dramatic impact on the fitness of human blood stem cells.

Chromosomal abnormalities in embryos created for IVF can be predicted at earliest stage of human development

Scientists at Oregon Health & Science University, Stanford University, University of Valencia and IGENOMIX have discovered that chromosomal abnormalities in human embryos created for in vitro fertilization, or IVF, can be predicted within the first 30 hours of development at the cell-1 stage which results from the union of a female egg and male sperm.

IRB Barcelona scientists provide molecular details about Seckel Syndrome

Today in Nature Communications, scientists at the Institute for Research in Biomedicine (IRB Barcelona) provide molecular details about Seckel Syndrome, a rare disease that causes microcephaly, or small brain, and growth delays.

Imaging proteasome complex helps show target site for potential cancer drugs

Scientists have pioneered the use of a high-powered imaging technique to picture in exquisite detail one of the central proteins of life - a cellular recycling unit with a role in many diseases.

Latent CMV infection induces telomere shortening

The telomeres are repetitive DNA sequences at each end of our chromosomes. Studies show that in every cell division, the telomere is shortened. As a result, the telomere limits the cell to a fixed number of divisions and a limited life span. An essential part of human cells they affect how our cells age - as people with longer telomeres live longer lives. Surprisingly, people who are infected with a latent virus, that is, an asymptomatic virus, have shorter telomeres.

Taranis protein could hold key to a good night's sleep

Most of us need seven to eight hours of sleep a night to function well, but some people seem to need a lot less sleep. The difference is largely due to genetic variability. In research published online June 18th in Current Biology, researchers report that two genes, originally known for their regulation of cell division, are required for normal slumber in fly models of sleep: taranis and Cyclin-dependent kinase 1 (Cdk1).

UCSF scientists identify characteristics of progenitor cells

University of California San Francisco scientists have identified characteristics of a family of daughter cells, called MPPs, which are the first to arise from stem cells within bone marrow that generate the entire blood system. The researchers said the discovery raises the possibility that, by manipulating the fates of MPPs or parent stem cells, medical researchers could one day help overcome imbalances and deficiencies that can arise in the blood system due to aging or in patients with specific types of leukemia.

Living in disadvantaged neighborhoods has direct impact on cellular health

Regardless of chronological age, people who live in neighborhoods with high crime, noise and vandalism are biologically more than a decade older than those who do not, according to a study led by researchers from the University of Pittsburgh.

New study shows that estrogen receptors vanish in cervical cancer tumors

Scientists have prior evidence that the hormone estrogen is a major driver in the growth of cervical cancer, but a new study examining genetic profiles of 128 clinical cases reached a surprising conclusion: Estrogen receptors all but vanish in cervical cancer tumors.

Yeast could serve as a test organism for study of human obesity

A team of biologists and a mathematician have identified and characterized a network composed of 94 proteins that work together to regulate fat storage in yeast.

Scientists reveal why lone kidney gets bigger when the other one is lost

Scientists have found an explanation for the century-old observation that if you end up with just one kidney, the lone organ gets bigger.

CNIO researchers identify new strategy to combat cancer

Scientists from the Spanish National Cancer Research Centre have discovered a new strategy to fight cancer, which is very different from those described to date. Their work shows for the first time that telomeres -- the structures protecting the ends of the chromosomes -- may represent an effective anti-cancer target: by blocking the TRF1 gene, which is essential for the telomeres, they have shown dramatic improvements in mice with lung cancer.

Obese people at greater risk of developing cancer

Cancer is more likely to develop in people who are very overweight (obese), because surplus body fat interferes with various hormone cycles and with glucose and fat metabolism. On the occasion of European Obesity Day this coming Saturday (16 May), metabolic expert Alexandra Kautzky-Willer, Comprehensive Cancer Center at MedUni Vienna and Vienna General Hospital, draws attention to the fact that, even in Austria, more and more people are suffering from obesity.

New study shows ulcer-causing bacteria can directly interact with stomach stem cells

The ulcer-causing bacterium Helicobacter pylori can directly interact with stomach stem cells, causing the cells to divide more rapidly, according to a new study by researchers at the Stanford University School of Medicine.

Max Planck Institute researchers find protein profiles of DNA repair

During each cell division, more than 3.3 billion base pairs of genomic DNA have to be duplicated and segregated accurately to daughter cells. But what happens when the DNA template is damaged in such a way that the replication machinery gets stuck? To answer this question, scientists in the team of Matthias Mann at the Max Planck Institute of Biochemistry in Martinsried near Munich, with colleagues in Copenhagen and at Harvard, have analyzed how the protein composition of the DNA replication machinery changes upon encountering damaged DNA.
