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.

UMass Amherst cell biologists propose new detailed cytokinesis model

Along with copying and splitting DNA during division, cells must have a way to break safely into two viable daughter cells, a process called cytokinesis. But the molecular basis of how plant cells accomplish this without mistakes has been unclear for many years.

Genetic mutation caused by ultraviolet light is likely driving force behind human skin cancers

A genetic mutation caused by ultraviolet light is likely the driving force behind millions of human skin cancers, according to researchers at the Stanford University School of Medicine.

Novogen, CanTx believe Intra-Peritoneal Trx-1 could be utilized as first-line therapy for ovarian cancer

Australian oncology drug development company Novogen Limited and CanTx Inc., its joint venture with Yale University, today announced the success of proof-of-concept pre-clinical studies confirming the potency of experimental drug, Trx-1, in the treatment of primary ovarian cancer when delivered into the peritoneal cavity.

Analysis of key cellular protein demonstrates the effectiveness of Taxol anti-cancer drug

A pathway to the design of even more effective versions of the powerful anti-cancer drug Taxol has been opened with the most detailed look ever at the assembly and disassembly of microtubules, tiny fibers of tubulin protein that form the cytoskeletons of living cells and play a crucial role in mitosis.

Stowers team reports genome-wide analysis of genes that drive cell division in multicellular organism

In textbooks, the grand-finale of cell division is the tug-of-war fought inside dividing cells as duplicated pairs of chromosomes get dragged in opposite directions into daughter cells.

Tumor suppressor gene linked to stem cell function

Just as archeologists try to decipher ancient tablets to discern their meaning, UT Southwestern Medical Center cancer biologists are working to decode the purpose of an ancient gene considered one of the most important in cancer research.

Subtle epigenetic change plays important role in correct segregation of chromosomes

Abnormal number of chromosomes is often associated with cancer development. In a new study published in the journal Nature Structural and Molecular Biology researchers at Karolinska Institutet in Sweden have shown that a subtle epigenetic change plays an important role in the correct segregation of chromosomes.

Researchers identify protein critical to hematopoietic stem cell function, blood formation

Researchers at the University of California, San Diego School of Medicine have identified a protein critical to hematopoietic stem cell function and blood formation. The finding has potential as a new target for treating leukemia because cancer stem cells rely upon the same protein to regulate and sustain their growth.
