DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Whole-genome sequencing can identify patients' risk for hereditary cancer

UT Southwestern Medical Center cancer researchers have demonstrated that whole-genome sequencing can be used to identify patients' risk for hereditary cancer, which can potentially lead to improvements in cancer prevention, diagnosis, and care.

Next generation sequencing in malignant pleural mesothelioma tumors reveals complex mutational setting

Next generation sequencing in malignant pleural mesothelioma (MPM) tumors shows a complex mutational setting with a high number of genetic alterations in genes involved in DNA repair, cell survival and cell proliferation pathways. Increased accumulation of mutations correlates with early progression of the tumor and decreased survival.

Endogenous retroviruses play critical role in body's immune defense against bacterial, viral pathogens

Retroviruses are best known for causing contagious scourges such as AIDS, or more sporadically, cancer.

Medical researchers at Saint Louis University bring hope to those in pain and sickness

This year, Saint Louis University medical researchers advanced their fields, contributing to human knowledge and bringing hope to those in pain and sickness.

Experimental Ebola vaccine safe and immunogenic in African population

Two experimental DNA vaccines to prevent Ebola virus and the closely related Marburg virus [1] are safe, and generated a similar immune response in healthy Ugandan adults as reported in healthy US adults earlier this year.

Study reveals why older people are at higher risk for developing cancer

Why are older people at higher risk for developing cancer? Prevailing opinion holds that, over time, your body's cells accumulate DNA damage and that eventually this damage catches up with the body in a way that causes cancer.

Offspring of mice treated with drug had delayed onset, reduced symptoms of Huntington's disease

Famine, drug abuse and even stress can "silence" certain genes, causing health problems in generations to come. Now scientists are wondering—could therapies that change gene expression in parents help their children?

Resveratrol activates ancient stress response in human cells, shows study

Scientists at The Scripps Research Institute (TSRI) have found that resveratrol, the red-wine ingredient once touted as an elixir of youth, powerfully activates an evolutionarily ancient stress response in human cells.

Researchers devise new technique to understand how neutrophils move in bodily tissues

Neutrophils, a type of white blood cell, are the immune system's all-terrain vehicles. The cells are recruited to fight infections or injury in any tissue or organ in the body despite differences in the cellular and biochemical composition.

Researchers identify new genetic anomalies in smoking-related lung cancers

Developing effective treatments for lung cancer has been challenging, in part because so many genetic mutations play a role in the disease.

Chromosome X microduplications implicated in infancy-onset gigantism

Researchers report that heritable microduplications on chromosome Xq26.3 may underlie a “striking” form of gigantism with onset in late infancy, and reveal a candidate culprit gene.

New computational technique reveals genetic roots of autism, cancers

In the decade since the genome was sequenced in 2003, scientists and doctors have struggled to answer an all-consuming question: Which DNA mutations cause disease?

FDA approves Myriad’s BRACAnalysis CDx for use with ovarian cancer drug

Myriad Genetics, Inc. today announced that it has received approval from the U.S. Food and Drug Administration (FDA) for BRACAnalysis CDx to be used as the only companion diagnostic in conjunction with AstraZeneca’s drug Lynparza™ (olaparib).

Study: Inactivating polymorphism may influence progression of ovarian and luminal breast cancer

A common polymorphism - a variation in a person's DNA sequence that is found with regularity in the general population - can lead to a chain of events that dictates how a tumor will progress in certain types of cancer, including a form of breast cancer as well as ovarian cancer, according to new research from The Wistar Institute that was published online by the journal Cancer Cell.

SLU investigators find promising candidates for new herpes virus treatments

Saint Louis University research findings published in the December issue of Antimicrobial Agents and Chemotherapy report a family of molecules known as nucleotidyltransferase superfamily (NTS) enzyme inhibitors are promising candidates for new herpes virus treatments.

Scientists develop new system for studying how proteins, other biological molecules unfold and refold

Collaborating scientists from The Scripps Research Institute and the University of California San Diego have developed a powerful new system for studying how proteins and other biological molecules form and lose their natural folded structures.

TUM researchers discover new mechanism for regulating programmed cell death

Programmed cell death is a mechanism that causes defective and potentially harmful cells to destroy themselves. It serves a number of purposes in the body, including the prevention of malignant tumor growth. Now, researchers at Technische Universität München have discovered a previously unknown mechanism for regulating programmed cell death.
