Not The Protein, But Its Location In The Cell, Determines The Onset Of Leukemia

10 years ago from Science Daily

Scientists are still searching for the cause of many forms of Leukemia, including T-cell acute lymphoblastic leukemia. Researchers have now discovered that the carcinogenic property of the fusion protein NUP214-ABL1...

Genes That Control Embryonic Stem Cell Fate Identified

10 years ago from Science Daily

Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they...

Mechanism That Explains How Cancer Enzyme Winds Up On Ends Of Chromosomes Found

10 years ago from Science Daily

Researchers have shown a mechanism that explains how two essential components of human telomerase -- normally active only in early prenatal development but turned back on during cancer growth --...

Purified Stem Cells Restore Muscle In Mice With Muscular Dystrophy

10 years ago from Science Daily

Researchers have demonstrated for the first time that transplanted muscle stem cells can both improve muscle function in animals with a form of muscular dystrophy and replenish the stem cell...

Molecular Motor Works By Detecting Minute Changes In Force

10 years ago from Science Daily

Researchers discovered that the activity of a specific family of nanometer-sized molecular motors called myosin-I is regulated by force. The motor puts tension on cellular springs that allow vibrations to...

Unsuspected Gene Mutation Found For Atrial Fibrillation

10 years ago from Science Daily

Researchers have found a gene mutation linked to one family's hereditary form of atrial fibrillation. The study was based on a large family with an inherited form of atrial fibrillation...

Learning Suffers If Brain Transcript Isn't Transported Far Out To End Of Neurons

10 years ago from Science Daily

Neuroscientists have solved a mystery that lies at the heart of human learning, and they say the solution may help explain some forms of mental retardation as well as provide...

Detecting Early Forms Of Cancer By Analyzing Structure of Specific Sugar Molecules

10 years ago from Science Daily

Scientists have developed a system which can pinpoint potential "biomarkers" of early forms of cancer, by looking at structures of specific sugar molecules which are attached either to proteins of...

Enzyme key to 'sister act' that maintains genome stability

10 years ago from Biology News Net

Keeping the genome stable is a "sister act" of matched chromatids – the pairs of the double helix DNA molecule that exist during the chromosome duplication in the S phase...

Crime scene DNA is typically recovered from blood or semen stains, but the DNA that exonerated members of JonBenet Ramsey's family came from invisible skin cells.

Scientists use genomic tools to create maps of DNA methylation

10 years ago from Physorg

(PhysOrg.com) -- Much of the field of stem cell biology and development remains uncharted territory. Just as famous explorers and astronomers mapped out landmasses and constellations, researchers are working fervently...

Researchers catch ion channels in their opening act

10 years ago from Physorg

Each thought or action sends a million electrical signals pulsing through your body. At the heart of the process of generating these electrical impulses is the ion channel.

Conservation areas 'attracting human settlement'

10 years ago from SciDev

Protected conservation areas attract human settlement rather than drive people away, which could threaten biodiversity, finds a study.

Researchers Hack Final Part Of The Immune System Code

10 years ago from Science Daily

Researchers have managed to decipher the final part of the immune system's key codes. The human body has its own natural inbuilt defense mechanism which uses access or “pincodes” to...

Scientists generate the most precise map of genetic recombination ever

10 years ago from Physorg

Genetic recombination, the process by which sexually reproducing organisms shuffle their genetic material when producing germ cells, leads to offspring with a new genetic make-up and influences the course of...
