Chromosome glue repairs damaged DNA

When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired.

Magnetic nano tweezers show how cancer drug works

The annoying bulges of an over-wound telephone cord that shorten its reach and limit a caller's motion help to explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators at St. Jude Children's Research Hospital and Delft University of Technology.

New insights into acute promyelocytic leukemia

Results from two new studies provide key mechanistic insights into the complex molecular events that cause a deadly type of leukemia.

New gene mutation linked to frontotemporal dementia

Researchers have identified a new gene mutation linked to frontotemporal dementia, according to a study published in the July 10, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Neutral genetic drift

Johns Hopkins researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.

ERG gene's activity points to more lethal subtype of acute myeloid leukemia

A new study shows that the activity of a particular gene can identify people who have a more lethal form of acute myeloid leukemia, singling out those patients who should receive more intense therapy.

Genetic risk factor for colorectal and prostate cancer

A study led by researchers at the Keck School of Medicine of the University of Southern California (USC) has found that one of seven genetic risk factors previously identified as increasing the probability of developing prostate cancer also increases the probability of developing colorectal cancer.

Chromosome disorders can arise when sex cells are formed

Chromosome disorders in sex cells cause infertility, miscarriage and irregular numbers of chromosomes (aneuploidy) in neonates.

Chromosome linked to colorectal cancer identified

Researchers at the Ontario Institute for Cancer Research and Cancer Care Ontario have successfully identified a specific genetic variation on chromosome 8 that is associated with colorectal cancer.

Discovery of new gene with links to childhood asthma

New treatments for childhood asthma could be in the pipeline following the discovery of a gene associated with the condition.

New working principle in cancer treatment

Due to defects in chromosomal distribution, a majority of tumor cells would not be able to survive were it not for a trick that cancer cells have developed to avoid this chaos in the genetic material.

Breakthrough new asthma gene found

In a large-scale study conducted with 2,643 children, international researchers with the participation of the Department of Experimental Pneumology of Ruhr-University Bochum (RUB), Germany (Prof. Dr. Albrecht Bufe), have discovered a gene variant that contributes significantly to the risk of childhood asthma.

Artificially replicating the male genome may help infertile men

Artificially replicating the male genome could help men with very low sperm counts become fathers, a scientist told the 23rd annual conference of the European Society of Human Reproduction and Embryology.

Asthma gene found

A gene that is strongly associated with a risk of developing childhood onset asthma was identified by an international team of scientists, whose findings are published in the journal Nature.

Mother donates eggs to infertile daughter

A Canadian mother has taken the unique step of donating her eggs to her daughter to ensure she can have a child.

RNA molecules can orchestrate gene activity across vast portions of the human genome

Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

Link between ciliary signaling and cancer

Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.

Protein ATM prevents DNA damage from persisting through generations

A protein long known to be involved in protecting a cell from genetic damage has been found to play an even more important role in protecting the cell's offspring.

Support for chromosomal theory of cancer found in cancers' development of drug resistance

Thirty-six years into the war on cancer, scientists have not only failed to come up with a cure, but most of the newer drugs suffer from the same problems as those available in the pre-war days: serious toxicity, limited effectiveness and eventual resistance.
