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).

Turning tumor-promoting fibroblasts against pancreatic cancer

Pancreatic cancer has a grim prognosis. It is usually detected after the disease has spread, and chemotherapy tends to do little to slow the cancer's growth. Even with treatment, most patients live only about six months after they are diagnosed with the disease.

Study uses data from 500,000 people to elucidate risks of obesity

Elevated body mass index - a measure of weight accounting for a person's height - has been shown to be a likely causal contributor to population patterns in mortality, according to a new study led by the University of Bristol using measurements and mortality data from 500,000 people.

'Cancer Gene Census' could help find drug targets and design treatments

Researchers at the Wellcome Sanger Institute have created the first comprehensive summary of all genes known to be involved in human cancer, the "Cancer Gene Census". Describing all genes strongly implicated in causing cancer, the Census also describes how they function across all forms of this disease.

New liquid biopsy test confirms remission in patients with HPV-associated oropharyngeal cancer

A highly sensitive blood test that detects minute traces of cancer-specific DNA has been shown to accurately determine whether patients with HPV-related oropharyngeal squamous cell carcinoma are free from cancer following radiation therapy.

New discovery may lead to better treatment options for pancreatic cancer patients

Pancreatic cancer is one of the most difficult cancers to treat and is a leading cause of cancer-related deaths. Now, Sidney Kimmel Cancer Center - Jefferson Health and Lankenau Institute for Medical Research scientists find that a gene involved in the immune system called IDO2 plays a significant role in pancreatic ductal adenocarcinoma, the most common type of pancreatic cancer.

Immunotherapy is better than chemotherapy as first-line treatment for advanced head and neck cancer

Immunotherapy on its own is better than aggressive chemotherapy as a first-line treatment for advanced head and neck cancer, according to surprising new data from a major phase III clinical trial.

23 Oct 2018

Cancer treatment may undergo a paradigm shift to immunotherapy soon

Immunotherapy when used for cancer treatment could extend life longer finds studies. Experts have explained that until now immunotherapy was reserved as a last resort for most patients and treatment usually comprised of chemotherapy and radiation therapy failing which these were tried. In a pair of clinical trials, researchers have found that using immunotherapy as first line treatment can extend lives of these cancer patients.
