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).

Researchers uncover unusual form of cross-talk between proteins that affect gene expression

Turning genes on and off is an intricate process involving communication between many different types of proteins that interact with DNA.

Ovarian cancer therapy may help treat patients with aggressive pancreatic cancer

A targeted therapy that has shown its power in fighting ovarian cancer in women including those with BRCA1 and BRCA2 mutations may also help patients with aggressive pancreatic cancer who harbor these mutations and have few or no other treatment options.

Lizards with bright green blood baffle scientists

A species of lizards has been found to have bright green blood. Researchers in their study published this Tuesday said that this finding could provide understanding in illnesses such as malaria and jaundice. The study was published in Science Advances.

Romaine lettuce contamination possibly towards conclusion says CDC

The Centers for Disease Control and Prevention (CDC) has released a report titled, “Multistate Outbreak of E. coli O157:H7 Infections Linked to Romaine Lettuce”, stating that it is safe to consume romaine lettuce which was implicated in transmitting a toxic strain of E. coli since March this year.

New blood test shows promise for early detection of pancreatic cancer

Pancreatic cancer is expected to become the second deadliest cancer in the United States by 2030. It is tough to cure because it is usually not discovered until it has reached an advanced stage. But a new diagnostic test developed by researchers at UC San Diego shows promise for detecting the disease earlier.

Pancreatic cancer patients with BRCA1 or BRCA2 mutations fare better on platinum-based chemotherapy

A small study of adults with the most common form of pancreatic cancer adds to evidence that patients with BRCA1 or BRCA2 gene mutations long linked to a high risk of breast cancer have poorer overall survival rates than those without the mutations.

Scientists discover how unusually long strands of RNA help colon cancer cells avoid death

Researchers from Case Western Reserve University School of Medicine have discovered how unusually long strands of RNA help colon cancer cells avoid death, allowing unregulated growth.

Researchers discover medulloblastoma subtype that responds to less aggressive therapy

The youngest patients with the brain tumor medulloblastoma are among the most challenging because their rapidly developing brains limit treatment options.

Scientists disrupt two enzymes to shrink cancer cells

Before cell division, the long strings of the cell's DNA are wrapped tightly into the structures we know as chromosomes. This protects the cell's genetic material from physical and chemical damage.

Mayo Clinic researchers identify new possible treatment choice for triple negative breast cancer

In a recent study published in the Journal of Clinical Investigation, Mayo Clinic researchers identified that an FDA drug approved for myelodysplastic syndrome may be useful to treat triple-negative breast cancer, which is one of the most aggressive and lethal types of breast cancer.

Study uncovers mechanism underlying brain malformation linked to severe epilepsy

One of the most frequent causes of drug-resistant epilepsy, considered a difficult disease to control, is a brain malformation known as focal cortical dysplasia.

Researchers are developing new algorithms to predict protein structure

With protein design dating back to the mid-1970s, today’s scientists have access to a huge amount of information and tools that they can use to create proteins – such abundant, diverse material, in fact, that the data they need may be hard to find.

First genomic survey of gonorrhea maps antibiotic resistance across Europe

The first European-wide genomic survey of gonorrhea has mapped antibiotic resistance in this sexually transmitted disease throughout the continent.

Prenatal test to determine child's rhesus factor found to be reliable, but benefit is unclear

If the blood of a pregnant woman is rhesus-negative and the blood of the fetus is rhesus-positive, the woman may develop antibodies, which can cause severe harm to subsequent children in particular.

Volatile biomarkers could help detect acute and asymptomatic malaria infections

Malaria is still a deadly disease in tropical and subtropical regions. Every year the disease infects more than 200 million people worldwide, claiming several hundred thousand victims.

Essential fats in diet may regulate protein secretion in muscles by altering gene expression

A new study reveals that essential fats in the diet may play a role in regulating protein secretion in the muscles by changing the way genes associated with secretion act.

Scientists find overlap between causes of RA and Huntington’s disease

Using new analytic tools, researchers at University of California San Diego School of Medicine and the Icahn School of Medicine at Mount Sinai have decoded the epigenetic landscape for rheumatoid arthritis (RA), a common autoimmune disease that affects more than 1.3 million Americans.
