Cleveland: Despite rapid advances in targeted therapies for cancer, tumors commonly develop resistance to treatment. When resistance emerges, tumor cells continue to grow unchecked, despite all attempts to slow cancer progression. While mutations in cancer cells significantly affect drug sensitivity, it is increasingly recognized that ecological interactions between cells can also play a role. Jacob

A Massachusetts General Hospital (MGH) research team has identified interaction between two elements of the immune system as critical for the transformation of a protective immune response into chronic, cancer-promoting inflammation. In their report published in PNAS, the investigators demonstrate that elevated levels of the immune factor IL-33 and regulatory T cells (Tregs), which suppress

Cardiff University researchers have uncovered new information about the underlying mechanisms for gastric cancer, providing hope of potential new therapies in the future. The team, at the University’s European Cancer Stem Cell Research Institute, found they could stop gastric cells dividing and growing by deleting a particular cell-surface receptor implicated in the function of stem

A new Tel Aviv University study finds that eosinophils — white blood cells that may have played an evolutionary role in combating parasites, but which are today responsible for chronic asthma and modern allergies — may be used to eliminate malignant colon cancer cells. The research was led by Prof. Ariel Munitz of the Department

Almost half of all Americans take a vitamin supplement, and yet many large-scale, placebo-controlled clinical trials of various supplements have found little or no benefit. A new study led by investigators from Brigham and Women’s Hospital suggests an intriguing reason for this: genetic variation may be influencing these effects, increasing risk in some individuals while

Treatment with capivasertib, a drug designed to work against a particular gene mutation found in some tumours, shows signs of being effective in a trial of 35 patients presented today (Tuesday) at the 30th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Dublin, Ireland. The phase 2 trial (EAY131-Y) is part of a larger

Scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now found a cause for the frequent catastrophic events in the genetic material of cancer cells that have only been known for a few years: If an important DNA repair system of the cells has failed, this promotes fragmentation and defective assembly of the

Researchers have discovered a novel consequence of loss of the tumour protein p53 that promotes cancer development, according to new findings in eLife. The study in mouse and human cells, from the Netherlands Cancer Institute, suggests that multiplication of cancer cells in the absence of appropriate growth stimuli is supported by the additional loss of

Simulations with animal models meant to mirror galactic cosmic radiation exposure to astronauts are raising red flags for investigators at Georgetown University Medical Center (GUMC) about the health of astronauts during long voyages, such as to Mars. Their most recent study, published in the Proceedings of the National Academy of Sciences (PNAS), suggests that deep

A team of Hokkaido University scientists studied the molecules involved in mitochondrial movements within highly invasive breast cancer cells. They identified a pathway that ultimately leads to the dispersion of these energy-generating organelles towards the cells’ periphery, increasing cancer invasiveness. When this pathway was blocked, mitochondria aggregated within the cell’s center, where they started overproducing

Routine testing for prostate cancer is not recommended for most men because the benefit is small and uncertain and there are clear harms, say a panel of international experts in The BMJ today. But they acknowledge that some men, such as those with a family history of prostate cancer, may be more likely to consider

Patients with muscle-invasive bladder cancer have been shown to benefit from chemotherapy prior to surgical removal of the bladder. But which type of chemotherapy leads to the best outcomes in terms of complete response rates or cancer control? Moffitt Cancer Center researchers examined data from more than 800 surgical patients with advanced bladder cancer. The

A UCLA-led study has found that a treatment that uses a bacteria-like agent in combination with an immunotherapy drug could help some people with advanced melanoma, an aggressive form of skin cancer, live longer. The research showed that using the immunotherapy drug pembrolizumab and the experimental agent SD-101, a sequence of nucleic acids that mimics

Childhood leukemia is a diagnosis that no family ever wants to endure. While the treatment of most types of leukemia has improved steadily over the years, a few specific types remain very difficult to treat. One of these is called “mixed lineage leukemia,” and for children affected by this cancer, their chance of survival is

When it comes to certain molecules, shape makes all the difference. The shape of limonene, for instance, a compound produced by citrus fruits, determines whether it tastes like orange juice or turpentine. In the case of therapeutics, the 3D shape of a molecule can be critical to activity. Now, scientists at Scripps Research and Bristol-Myers

A Massachusetts General Hospital (MGH) research team has used epigenome editing tools to investigate how the genetic abnormality that drives Ewing sarcoma — the second most common bone cancer in children and young adults — unleashes tumor growth. In their paper in the journal Genes & Development the researchers show that blocking the fusion protein

Scientists headed by ICREA researcher Angel R. Nebreda at the Institute for Research in Biomedicine (IRB Barcelona) report a new mechanism that contributes to the development of inflammation-associated colon cancer and points to new therapeutic targets. The study has been published in the journal EMBO Molecular Medicine. More than a million people worldwide are diagnosed

A team of researchers from Queen Mary University of London have reported the genetic events involved in the early development of bowel cancer in patients with inflammatory bowel disease (IBD). Such knowledge may be able to be exploited to design simple diagnostic tests to stratify patients with IBD at high risk of developing cancer. IBD

A new study of prostate cancer in 202 men, whose cancers had spread and were resistant to standard treatment, found that a surprisingly large number of these cancers — about 17 percent — belong to a deadlier subtype of metastatic prostate cancer. Previously, it was thought that these cancers constituted less than 1 percent of

A new microscope system can image living tissue in real time and in molecular detail, without any chemicals or dyes, report researchers at the University of Illinois. The system uses precisely tailored pulses of light to simultaneously image with multiple wavelengths. This enables the researchers to study concurrent processes within cells and tissue, and could
