Accumulation of passenger mutations can slow or even halt tumor growth

A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression.

Non-coding RNA essential for normal embryonic cardiogenesis

Many different tissues and organs form from pluripotent stem cells during embryonic development. To date it had been known that these processes are controlled by transcription factors for specific tissues. Scientists from the Max Planck Institute for Molecular Genetics in Berlin, in collaboration with colleagues at MIT and the Broad Institute in Boston, have now been able to demonstrate that RNA molecules, which do not act as templates for protein synthesis, participate in these processes as well.

DRCRF announces recipients of Nov. 2012 Damon Runyon Fellows

The Damon Runyon Cancer Research Foundation, a non-profit organization focused on supporting innovative early career researchers, named 15 new Damon Runyon Fellows at its fall Fellowship Award Committee review.

Telomerase gene mutation immortalizes deadly skin cancer

About ten percent of all cases of malignant melanoma are familial cases. The genome of affected families tells scientists a lot about how the disease develops. Prof. Dr. Rajiv Kumar of the German Cancer Research Center together with Prof. Dr. Dirk Schadendorf from Essen University Hospital studied a family where 14 family members were affected by malignant melanoma.

Study shows how GATA3 protein acts downstream biochemically to prevent breast cancer metastasis

The spread of breast cancer to distant organs within the body, an event that often leads to death, appears in many cases to involve the loss of a key protein, according to UC San Francisco researchers, whose new discoveries point to possible targets for therapy.

Genome sequencing data gives important clues on cancer

Genome sequencing data once regarded as junk is now being used to gain important clues to help understand disease.

Research shows brain cells regulate blood vessel development

Zhen Huang freely admits he was not interested in blood vessels four years ago when he was studying brain development in a fetal mouse. Instead, he wanted to see how changing a particular gene in brain cells called glia would affect the growth of neurons.

New details about molecular surveillance system that helps detect and correct errors in cell division

Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.

Scientists identify a possible lead in treatment of two childhood leukemia subtypes

Research led by St. Jude Children's Research Hospital scientists has identified a possible lead in treatment of two childhood leukemia subtypes known for their dramatic loss of chromosomes and poor treatment outcomes.

G-quadruplexes also exist within the human genome

In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving 'double helix' DNA structure - the chemical code for all life.

Scientists identify new mechanism for schistosomiasis-bladder cancer connection

About 200 million people across 75 of the poorest countries in the world are now infected by the blood parasite Schistosoma haematobium (S. haematobium). The infection causes severe urogenital disease, but also causes bladder cancer in a number of patients and why this occurs is not clear.

Young humans capable of generating new heart muscle cells

Researchers at Boston Children's Hospital have found, for the first time that young humans (infants, children and adolescents) are capable of generating new heart muscle cells.

Combination of pazopanib and paclitaxel shows promise in slowing anaplastic thyroid cancer

A combination of the drugs pazopanib and paclitaxel shows promise in slowing anaplastic thyroid cancer (ATC), according to a Mayo Clinic-led study published in the journal Science Translational Medicine.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

Novel approach to sort out good or bad mutations associated with lymphoma

As anyone familiar with the X-Men knows, mutants can be either very good or very bad - or somewhere in between. The same appears true within cancer cells, which may harbor hundreds of mutations that set them apart from other cells in the body; the scientific challenge has been to figure out which mutations are culprits and which are innocent bystanders.

Scientists develop two novel model systems for human corneal endothelium

Human corneal endothelial cells (HCEnCs) form a monolayer of hexagonal cells whose main function is to maintain corneal clarity by regulating corneal hydration. Cell loss due to aging or corneal endothelial disorders, such as Fuchs dystrophy, can lead to cornea edema and blindness, resulting in the need for cornea transplants.

New light on genome replication

New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome replication and may offer insights into the factors behind the production of abnormal numbers of chromosomes.

BubR1 and its associated regulators promising targets for aging disorders and cancer

A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span. The findings appear in today's online issue of Nature Cell Biology.

Klerokinesis may prevent some cancers from developing

Researchers at the University of Wisconsin Carbone Cancer Center have discovered a new form of cell division in human cells.

Study reveals how BRCA1 enzymatic activity may stop cancer cell growth

A new study by Georgetown University Medical Center researchers reveals how a well-known tumor suppressor gene may be functioning to stop cancer cell growth.
