New Mexico contains hundreds of historic uranium mines. Although active uranium mining in the state has ceased, rates of cardiovascular and metabolic disease remain high in the population residing close to mines within the Navajo Nation. According to a new study in ACS’ journal Environmental Science & Technology Letters, inhaled uranium in dusts from the

A powerful new biochemical platform is fueling the study of a family of enzymes that are promising targets for cancer treatment. Published today in Science Advances, the new method provides a high-resolution view of how these enzymes, called lysine methyltransferases, selectively mark proteins with chemical tags that alter their function. Because of their central role

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

When a cell divides — a process known as mitosis — its chromosomes need to be separated and evenly distributed into the newly created daughter cells. Although this is known to be extremely complicated and to feature a range of cellular components, many of its details remain unclear, which has hampered efforts to develop treatments

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

A phase I clinical trial investigating the use of bacterial Clostridium novyi-NT spores as an injectable monotherapy had manageable toxicities and showed early clinical efficacy in patients with treatment-refractory solid tumor malignancies, according to data presented at the Fourth CRI-CIMT-EATI-AACR International Cancer Immunotherapy Conference: Translating Science into Survival, held Sept. 30-Oct. 3. “Even after a

Scientists have known for decades that certain bacteria produce small spherical versions of themselves. Although they lack basic materials to reproduce or function like normal cells, recent interest in such “minicells” has spiked due to their proficiency as nano-sized delivery tools for drugs and vaccines to targeted cells and tissues. Yet the natural role of

A new cell culture platform allows researchers to observe never-before-seen behaviors of live cancer cells under the microscope, leading to explanations of long-known cancer characteristics. The easy-to-produce platform developed by Hokkaido University researchers offers cancer cells micro-scale attachment sites that elicit never-before-seen behaviors highly relevant to cancer’s clinical properties. The observation of these behaviors shed

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

Cancer researchers struggle to identify tumor cells that are interspersed within nonmalignant tissues because tumor cells exploit the tissue environment and monopolize available resources to continue growing. Researchers attribute cancer cell’s ability to use cell signaling and metabolic pathways that override normal cell growth restrictions to complicated chemical exchanges between tissue and tumor cells. A

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

A new combination of existing drugs shows promise that it could reduce the size of cancerous tumors much more effectively than current treatments. As cancer patients know all too well, many highly effective anti-cancer drugs don’t stay effective long. Most tumors will become drug resistant over time as their cells rapidly mutate. Chemists from The

In the first experiment of its kind, scientists have revealed the precise identity of cancer cells of the most common childhood and adult kidney cancers. Researchers from the Wellcome Sanger Institute, the University of Cambridge, University of Newcastle and their collaborators showed that the cancer cells are versions of specific healthy cells from developing or

Certain molecular drivers of cancer growth are “undruggable” — it’s been nearly impossible to develop chemicals that would block their action and prevent cancer growth. Many of these molecules function by passing cancer-promoting information through a gate in the nucleus, where the instructions are carried out. Researchers at the Sidney Kimmel Cancer Center — Jefferson

Researchers report in Nature Communications they figured out why air sacs in the lungs clog up with a thick substance called surfactant in a brutal disease called Pulmonary Alveolar Proteinosis (PAP), and they show taking cholesterol-busting pills called statins can effectively treat the disease. That’s good news for people with PAP because at present the

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

In an alarming new research study, researchers have stated that lung cancer mortality rates among women could increase by 43% by 2030. The findings are according to an analysis of data from 52 countries. The global age-standardised breast cancer mortality rate is projected to decrease by 9% in the same time frame. Globally, among women,
