Links between a number of common respiratory diseases and an increased risk of developing lung cancer have been found in a large pooled analysis of seven studies involving more than 25,000 individuals.
Melbourne researchers have revealed the critical importance of highly specialized immune cells, called natural killer cells, in killing melanoma cells that have spread to the lungs. These natural killer cells could be harnessed to hunt down and kill cancers that have spread in the body.
A modified version of the Clostridium novyi (C. novyi-NT) bacterium can produce a strong and precisely targeted anti-tumor response in rats, dogs and now humans, according to a new report.
In this episode of Bioscience Technology This Week, Rob Fee discusses how studying fruit flies could revolutionize diabetes research. Our second story focuses on how venom could form the basis of a new class of cancerfighting drugs.
Scientists have known for decades that cancer can be caused by genetic mutations, but more recently they have discovered that chemical modifications of a gene can also contribute to cancer. These alterations, known as epigenetic modifications, control whether a gene is turned on or off.
Oncologists are melding magnetic resonance imaging (MRI) technology with a traditional ultrasound prostate exam to create a three-dimensional map of the prostate that allows physicians to view growths that were previously undetectable.
Researchers at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified a gene that contributes to the development of several childhood cancers, in a study conducted with mice designed to model the cancers. If the findings prove to be applicable to humans, the research could lead to new strategies for targeting certain childhood cancers at a molecular level.
Researchers from The University of Texas at Austin and five other institutions have created a molecule that can cause cancer cells to self-destruct by ferrying sodium and chloride ions into the cancer cells. These synthetic ion transporters confirm a two-decades-old hypothesis that could point the way to new anticancer drugs while also benefiting patients with cystic fibrosis.
Dangerous brain tumors hijack the brain’s existing blood supply throughout their progression, by growing only within narrow potential spaces between and along the brain’s thousands of small blood vessels, new research shows for the first time.
Researchers have hijacked a defense system normally used by bacteria to fend off viral infections and redirected it against the human papillomavirus (HPV), the virus that causes cervical, head and neck, and other cancers.Using the genome editing tool known as CRISPR, the Duke University researchers were able to selectively destroy two viral genes responsible for the growth and survival of cervical carcinoma cells.
Scientists from the University of Leeds have discovered a gene that plays a vital role in blood vessel formation, research which adds to our knowledge of how early life develops. The discovery could also lead to greater understanding of how to treat cardiovascular diseases and cancer.
Cancer cells that break away from tumors to go looking for a new home may prefer to settle into a soft bed. Some particularly enterprising cancer cells can cause a cancer to spread to other organs, called metastasis, or evade treatment to resurface after a patient is thought to be in remission. A team found that these so-called tumor-repopulating cells may lurk quietly in stiffer cellular environments, but thrive in a softer space.
Researchers with The Cancer Genome Atlas (TCGA) Research Network have completed the largest, most diverse tumor genetic analysis ever conducted, revealing a new approach to classifying cancers. The work not only revamps traditional ideas of how cancers are diagnosed and treated, but could also have a profound impact on the future landscape of drug development.
It's long been known that faulty BRCA genes greatly raise the risk for breast cancer. Now, scientists say a more recently identified, less common gene - called PALB2 - can do the same.
Researchers have achieved a technical breakthrough that should result in speedier diagnosis of cancer and various pre-natal conditions. The key discovery lies in a new tool that allows researchers to load long strands of DNA into a tunable nanoscale imaging chamber in ways that maintain their structural identity and under conditions that are similar to those found in the human body.
A large DNA analysis of people with and without pancreatic cancer has identified several new genetic markers that signal increased risk of developing the highly lethal disease, scientists report.
Researchers report that dietary capsaicin– the active ingredient in chili peppers– produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.
In what is believed to be the largest genetic analysis of what triggers and propels progression of tumor growth in a common childhood blood cancer, researchers report that they have identified a possible new drug target for treating the disease.
Just as no two people possess the same genetic makeup, a recent study has shown that no two single tumor cells in breast cancer patients have an identical genome.
The best way to cure most cases of cancer is to surgically remove the tumor. The Achilles heel of this approach, however, is that the surgeon may fail to extract the entire tumor, leading to a local recurrence. With a new technique, researchers at the University of Pennsylvania have established a new strategy to help surgeons see the entire tumor in the patient, increasing the likelihood of a positive outcome.
Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200 percent jump in deadly melanoma cases since 1973.
When cancers spread into the bloodstream, they often take on different characteristics, requiring different therapies. But it is hard to find these rare blood-borne cells. So, relapsed patients often do not get personalized care. Now, researchers have come up with a solution that zeros in on elusive circulating tumor cells (CTCs).
Researchers have identified a mechanism that overrides the cells’ warning signals, enabling cancers to continue to divide even without a robust blood supply.
In a massive effort to catalog the molecular causes of stomach cancer, scientists have identified four subtypes of tumors based on shared mutations and other molecular abnormalities.
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study by Tulane University School of Medicine cancer researchers.
