Pyromaker can rapidly sequence cancer-driving mutations

Using precise information about an individual's genetic makeup is becoming increasingly routine for developing tailored treatments for breast, lung, colon and other cancers. But techniques used to identify meaningful gene mutations depend on analyzing sequences of both normal and mutant DNA in tumor samples, a process that can yield ambiguous results. Now, a team of Johns Hopkins researchers says it has developed an easy-to-use online computer software application that can clear up any confusion faster and cheaper than other methods currently used to do the job.

Chemists create new molecule that can tangle inside the DNA for up to 16 days

Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.

Epigenetic mechanisms maintain tolerance in T cells specific for self antigens

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens).

New software key for personalized cancer medicine

High-throughput DNA sequencing technologies are leading to a revolution in how clinicians diagnose and treat cancer. The molecular profiles of individual tumors are beginning to be used in the design of chemotherapeutic programs optimized for the treatment of individual patients.

UC Riverside uncovers new insight into colon cancer

An international research team led by cell biologists at the University of California, Riverside has uncovered a new insight into colon cancer, the third leading cause of cancer-related deaths in the United States. The research provides potential new avenues for diagnosing and treating the disease.

Pyromaker can more accurately identify complex genetic mutations

DNA sequencing to detect genetic mutations can aid in the diagnosis and selection of treatment for cancer. Current methods of testing DNA samples, Sanger sequencing and pyrosequencing, occasionally produce complex results that can be difficult or impossible to interpret. Scientists at the Johns Hopkins University School of Medicine have developed a free software program, Pyromaker, that can more accurately identify such complex genetic mutations.

Cancer Genomics now available online

Genome Research publishes online and in print today a special issue entitled, "Cancer Genomics," highlighting insights gained form cutting-edge genomic and epigenomic analyses of cancer.

Newly discovered molecular pathway may explain how AML develops

Researchers at UC Santa Barbara have discovered a molecular pathway that may explain how a particularly deadly form of cancer develops. The discovery may lead to new cancer therapies that reprogram cells instead of killing them. The findings are published in a recent paper in the Journal of Biological Chemistry.

DNA sequencing for difficult diagnoses of mitochondrial diseases may hit clinics soon

Identifying complete DNA sequences could identify difficult-to-diagnose diseases in humans. This concept is being used for the first time in a clinic. MitoExome sequencing uses new technologies known as next-generation sequencing (NGS) to decode all of the genes associated with mitochondria. Mitochondria are a capsule shaped organelle present within the cell. It is the powerhouse of the cell and its genes are inherited completely from the mother.

Genes may predict maintenance of intelligence over lifetime: Study

A Scottish study that began 80 years ago has shown that genes may play a role in maintaining intelligence till old age. The study participants joined when they were 11 years old. Researchers have long been interested in understanding how cognition changes with age, and why these changes are more rapid in some people than in others. But, in the past, studies of age-related intelligence changes were often performed when the subjects were already elderly.

Study explains gender-related incidence of liver cancer

Men are four times more likely to develop liver cancer compared to women, a difference attributed to the sex hormones androgen and estrogen. Although this gender difference has been known for a long time, the molecular mechanisms by which estrogens prevent -- and androgens promote -- liver cancer remain unclear.

Genetic link to prostate cancer discovered

A new study has found that men who inherit a rare genetic mutation are 10 to 20 times more likely than average to develop prostate cancer. The gene variant may help explain cases of the disease that run in families and strike men at unusually young ages.
