Comet supercomputer reveals the mechanical process of cancer growth

According to the World Health Organization, one in six worldwide deaths have been attributed to cancer; however, these fatalities were not due to initial malignant tumors-;the deaths were caused by the spread of cancer cells to surrounding tissues and subsequent tumor growth. These tissues, which consist largely of collagen, have been the focus of a

Scientists receive grant to investigate tumor development within a natural environment

Unlike many of us during the COVID-19 pandemic, biological cells are not isolated from the outside world. Chemical variations, intercellular activity, and other microenvironmental factors impact cell survival. The relationship between cell and environment also applies to the development of cancer, which a team of Virginia Tech scientists is now researching. After receiving a $1.4

COVID-19 and lung cancer have a common pathway, say researchers

The coronavirus disease 2019 (COVID-19) is a transmissible viral disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen responsible for the ongoing global pandemic. The virus was first detected in Wuhan, China, at the end of 2019 and to date has caused over 109 million infections worldwide. With over 2.4 million

Discovery offers novel possibilities to target drug-resistant HER2-positive cancers

SORLA is a protein trafficking receptor that has been mainly studied in neurons, but it also plays a role in cancer cells. Professor Johanna Ivaska's research group at Turku Bioscience observed that SORLA functionally contributes to the most reported therapy-resistant mechanism by which the cell-surface receptor HER3 counteracts HER2 targeting therapy in HER2-positive cancers. Removing

A more sensitive way to detect circulating tumor cells

Breast cancer is the most frequently diagnosed cancer in women, and metastasis from the breast to other areas of the body is the leading cause of death in these patients. Detecting circulating tumor cells (CTCs) in the bloodstream could help doctors find and treat metastases at an earlier stage, increasing chances of survival. Now, researchers

New research supports clinical utility of circulating tumor cell count for metastatic breast cancer

Menarini Silicon Biosystems has announced the publication of a research study providing support for the reliability of using circulating tumor cell (CTC) count to guide frontline therapy choice for patients with estrogen receptor-positive (ER+), HER2-negative (HER2) metastatic breast cancer. Published in the November issue of JAMA Oncology, this is the first study to support clinical

Focused ultrasound shows promise against deadliest brain tumor

An innovative use of focused ultrasound being pioneered at the University of Virginia School of Medicine is showing promise against glioblastoma, the deadliest brain tumor, and could prove useful against other difficult-to-treat cancers. The technique hits cancer cells with a drug that sensitizes them to sound waves, then blasts them with focused ultrasound. The sound

Traces of immortality in tumor DNA

To gain an infinite lifespan, cancer cells need to maintain the ends of their chromosomes, known as telomeres. They achieve this in various ways. Scientists from the German Cancer Research Center systematically investigated more than 2,500 tumor genomes of 36 types of cancer to find out how these mechanisms are manifest in changes in the

Preventing tumor metastasis

Researchers at the Paul Scherrer Institute, together with colleagues from the pharmaceutical company F. Hoffmann-La Roche AG, have taken an important step toward the development of an agent against the metastasis of certain cancers. Using the Swiss Light Source, they deciphered the structure of a receptor that plays a crucial role in the migration of

This Woman's Brain Tumor Symptoms Were Dismissed as Headaches

After 15 trips to the doctor for migraines, Beckie Hiley’s symptoms were still dismissed. The UK 19-year-old spent months dealing with crippling headaches that were completely hindering her from living a normal life—she couldn’t go to work or school, and she could barely keep food down. Despite her debilitating symptoms, doctors told her her pain
