SIAVASH PARKHIDEH MEDICINE, NANOMEDICINE, ONCOLOGY Researchers from Duke University have developed a new DNA-based tool to identify cancer cells. Their system is a DNA circuit. DNA binding to specific cell markers produces a signal if and only if two specific proteins are present, helping to improve specificity and reduce false positives in cancer cell detection....

Cancer researchers discover how immune cells avoid killing themselves
By Michael Irving We have a lot to thank our immune systems for, as they remain ever-vigilant to protect us from cancer and infections. But exactly how do immune cells avoid wiping themselves out while attacking invaders? Researchers at Australia’s Peter MacCallum Cancer Centre and the University College London (UCL) have now found that they...

Eliminating Common Bacterial Infection Significantly Decreases Gastric Cancer Risk
While it is well known within the medical community that there is a link between the bacteria Helicobacter pylori (H pylori) and rates of gastric cancer—commonly referred to as stomach cancer—the rates and risk among Americans has been largely understudied. Now, after analyzing records of close to 400,000 patients, researchers in the Perelman School of...

Forget the Chardonnay, pass me the grape stems: Anti-tumor activity in prostate cancer cells
by Shinshu University Grape stems are discarded en masse during the production of wine. We love and produce a lot of wine in Nagano prefecture, and have been hoping to find a positive use for the previously discarded grape stems. Scientists at Shinshu University studied compounds within grape stem extracts and found significant anti-cancer activity...

3D-printed device finds ‘needle in a haystack’ cancer cells by removing the hay
GEORGIA INSTITUTE OF TECHNOLOGY Finding a handful of cancer cells hiding among billions of blood cells in a patient sample can be like finding a needle in a haystack. In a new approach enabled by 3D-printed cell traps, researchers are removing the hay to expose the cancer cells. Trapping the white blood cells – which...

Study sheds new light on the growth of bladder cancer
by Curtin University New Curtin University-led research has discovered that using drugs to target a pathway in the body that causes cancerous cells to spread aggressively may help to reduce the severity of bladder cancer. The research, published in Nature Communications, aimed to understand the function of two naturally occurring proteins called hepatocyte growth factor...

Research Identifies Proteins Responsible for Cancer Spreading
Posted Yesterday Advances in the sciences have made it easier than ever to live with and survive various kinds of cancer. One of the lingering challenges that remains is metastasis, or the ability of cancer cells to migrate to new pathological sites within the host’s body. October is National Breast Cancer Awareness Month. Too many...

Repurposing heart drugs to target cancer cells
by MRC London Institute of Medical Sciences Senescence is a cellular stress response that results in the stable growth arrest of old and damaged cells. The past decade has revealed that senescent cells play important roles in a growing list of diseases from cancer, to arthritis, atherosclerosis and many more. Previous studies have shown that...

A compound effective to chemotherapy-resistant cancer cells identified
HOKKAIDO UNIVERSITY A compound effective in killing chemotherapy-resistant glioblastoma-initiating cells (GICs) has been identified, raising hopes of producing drugs capable of eradicating refractory tumors with low toxicity. Despite longstanding and earnest endeavors to develop new remedies, the prognosis of most glioblastoma patients undergoing chemotherapies and radiotherapies remains poor. Glioblastoma, a malignant glioma, has a median...
