They have identified new functions of cohesin SA1 that are relevant for cancer and CdLS Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their functional specificity has been largely ignored. Researchers of the Spanish National Cancer Research Centre (CNIO) under the direction of Ana Losada have identified new functions of...

(Ivanhoe Newswire) -- In today's society, kids already act and look older than they are. Recent research has proved that the DNA of 10-year-olds who have experienced violence at a young age are found to show wear and tear normally associated with aging. "This is the first time it has been shown that our telomeres can shorten at a faster rate even at a really young age, while kids are still experiencing stress," Idan Shalev, a post-doctoral researcher in psychology and neuroscience at the...

Children Age Faster When Exposed To Violence And Bullying

Researchers have found that violence in the lives of children can cause changes in their DNA equivalent to seven to 10 years of premature aging. Scientists measured this cellular aging by studying the ends of children´s chromosomes, called telomeres. Telomeres are DNA sequences that act like the plastic tips on shoelaces, which prevent the DNA in chromosomes from unraveling. Each time a cell divides, the telomeres become shorter until a cell dies when it can´t divide anymore,...

Children who have experienced violence might really be older than their years. The DNA of 10-year-olds who experienced violence in their young lives has been found to show wear and tear normally associated with aging, a Duke University study has found. "This is the first time it has been shown that our telomeres can shorten at a faster rate even at a really young age, while kids are still experiencing stress," said Idan Shalev, a post-doctoral researcher in psychology and neuroscience at...

Russians born during the Leningrad Siege in World War II, which was responsible for some of the greatest losses of civilian life in history, are giving scientists new strategies to identify people who experienced intrauterine growth restriction (IUGR) and starvation during childhood at greatest risk of developing long term heart complications.vThe abstract study´, presented at the Frontiers in CardioVascular Biology (FCVB) meeting, in London, UK, 30 March to 1 April 2012, makes use of a...

Predicting Risk Of Heart Attacks With Chromosome Length
2012-03-26 12:19:20

Scientists in Boston, Massachusetts have discovered a chromosomal link to heart cancer by studying the length of proteins in a chromosome. The key factor at play in this research are telemores, or DNA protein complexes. These protein complexes can be thought of as “caps”, protecting chromosomes from deteriorating and melding with other chromosomes. As time goes on and chromosomes continue to replicate and cells divide, these telemores will naturally shorten. How much these...

Worm model of back-up telomere repair strategy could speed identification of anti-cancer drugs Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear of telomeres, the protective caps at the end of each chromosome. Loss of telomeres forces cells out of the dividing game and into a growth arrest state called "senescence," but cancer cells evade this by employing an enzyme called telomerase to extend eroded...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
