Understanding the workings of error correction mechanism in cell division

Cell biologists led by Thomas Maresca at the University of Massachusetts Amherst, with collaborators elsewhere, report an advance in understanding the workings of an error correction mechanism that helps cells detect and correct mistakes in cell division early enough to prevent chromosome mis-segregation and aneuploidy, that is, having too many or too few chromosomes.

Study stresses importance of investigating telomeres to improve diagnoses, develop treatments for many diseases

Studying telomeres, the structures that protect the ends of chromosomes, has become a key issue in biology. In recent years, not only has their relation to ageing been confirmed; defective telomeres seem to be linked to more and more illnesses, including many types of cancer.

Chromosomes play active role in animal cell division

Canadian and British researchers have discovered that chromosomes play an active role in animal cell division. This occurs at a precise stage - cytokinesis - when the cell splits into two new daughter cells.

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.

New research shows how human immune system could be manipulated to better fight disease

New research from Australian and Singaporean scientists has revealed how immune cell 'spies' are created, providing clues on how the immune system could be manipulated to better fight disease.

New JIC research helps to settle important debate on epigenetic inheritance

New research findings by John Innes Centre scientists have helped to settle an important debate in the field of epigenetic inheritance. Using the flowering plant Arabidopsis thaliana as a model for their research, Professor Martin Howard, Professor Caroline Dean and members of their labs, have been trying to understand how organisms 'remember' past events at the cellular level.

Genetically-programmed probiotics could help detect liver cancer metastases early-on

Scientists at the University of California, San Diego and the Massachusetts Institute of Technology have described a new method for detecting liver cancer metastases in mice. The approach uses over-the-counter probiotics genetically programmed to produce signals easily detectable in urine when liver cancer metastases are present.

Secret to the life-long activity of a stem cell niche

The roots of a plant are constantly growing, so that they can provide the plant with water and minerals while also giving it a firm anchor in the ground. Responsible for these functions are pluripotent stem cells. In order to avoid differentiation and to remain pluripotent, these stem cells are dependent on signals from their neighbouring cells.

Study reveals new molecular mechanism that helps protect genome from harmful effect of UV radiations

Researchers have uncovered a new molecular mechanism whereby human cells protect their genome from the detrimental effect of UV radiation and govern DNA replication in cellular mitosis, which, when it malfunctions, leads to harmful results.

Overexpression of cyclin E protein could lead to breast cancer, leukemia

A new study led by scientists at The Scripps Research Institute sheds light on the cause of some cancers, including breast cancer and leukemia.

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.

Research may point to new paradigms in diagnosis, treatment of aggressive cancers

All living things--from dandelions to reindeer--evolve over time. Cancer cells are no exception, and are subject to the two overarching mechanisms described by Charles Darwin: chance mutation and natural selection.

Mitochondrial DNA movement: an interview with Professor Jiri Neuzil, Griffith University

According to our understanding, mitochondria undergo cycles of fusion-fission, i.e. they divide within the constraints of a cell and, upon cell division, each of the two daughter cells gets its ‘share’ of mitochondria.

USF researchers uncover how malaria-related parasites spread at explosive rates

A University of South Florida College of Public Health professor and his team of researchers have become the first to uncover part of the mysterious process by which malaria-related parasites spread at explosive and deadly rates inside humans and other animals.

Researchers show importance of DNA damage in fine tuning of innate immune system

For the first time scientists from Umeå University show the importance of DNA damage in fine tuning of our innate immune system and hence the ability to mount the optimal inflammatory response to infections and other biological dangers.

Johns Hopkins researchers propose novel cancer-fighting strategy

Existing cancer therapies are geared toward massacring tumor cells, but Johns Hopkins researchers propose a different strategy: subtly hardening cancer cells to prevent them from invading new areas of the body. They devised a way of screening compounds for the desired effect and have identified a compound that shows promise in fighting pancreatic cancer.

Scientists challenge prevailing view of how bowel cancer develops in the large intestine

A new study that challenges the prevailing view of how bowel cancer develops in the large intestine is published today in Nature Medicine.

Research findings could provide new insights into esophageal cancer, Barrett's esophagus

Despite previous indications to the contrary, the esophagus does have its own pool of stem cells, said researchers from the University of Pittsburgh School of Medicine in an animal study published online today in Cell Reports.

Research finding could potentially lead to new strategies to improve cancer therapies

Cells are generally able to repair spontaneous damage that arises in their genetic material. Unfortunately, the DNA repair process is not perfect and sometimes, damaged DNA gets passed on to newly made cells. A team of researchers at the Center for Molecular Biology of Heidelberg University has recently discovered that in yeast cells, the amount of nutrients that cells are exposed to can affect DNA surveillance and repair mechanisms and therefore the quality of their DNA.
