UCLA researchers found that men who aren’t well educated about their disease have a much more difficult time making treatment decisions, called decisional conflict, a challenge that could negatively impact the quality of their care and their long-term outcomes. …
Cancer therapies cause unwanted proteins to accumulate in cancer cells, which can trigger a form of cell suicide known as apoptosis. To survive, the cells break down the excess proteins through autophagy, from a Greek term meaning “self eating.” In a study recently published in the journal Molecular and Cellular Biology, scientists induced autophagy using the anti-tumor drug obatoclax while simultaneously blocking the production of p62 using a drug known as a cyclin-dependant kinase (CDK) inhibitor. …
Researchers from the Cancer Research UK Manchester Institute based at The University of Manchester — part of the Manchester Cancer Research Centre — and the Institute of Cancer Research, London, looked at protein kinases, molecules that control various aspects of cellular function. …
“Regardless of the type of solid tumor, the pattern of methylation is much different on the genomes of cancerous cells than in healthy cells,” says Andrew Feinberg, M.D., M.P.H., a professor of medicine, molecular biology and genetics, oncology, and biostatistics at the Johns Hopkins University School of Medicine. …
“These are amazingly useful particles,” noted co-first author Yuanpei Li, a research faculty member in the Lam laboratory. “As a contrast agent, they make tumors easier to see on MRI and other scans…
Colin Collins and Alexander Wyatt, and other researchers from the Vancouver Prostate Centre at the Vancouver Coastal Health Research Institute, matched 25 patients’ treatment outcomes with the RNA sequence of their prostate cancer tumors. They suggest that similarities between the RNA of some of the patients’ tumors could open up new avenues of treatment. Prostate cancer is the fourth most common cancer worldwide, but can be effectively managed…
Cancer is deadly in large part due to its ability to metastasize, to travel from one organ or tissue type to another and malignantly sprout anew. The vast majority of cancer deaths are associated with metastasis…
“There is a growing interest to guide cancer therapy by sequencing the DNA of the cancer cell,” said Clark Chen, MD, PhD, vice-chairman of Research and Academic Development, UC San Diego Division of Neurosurgery and the principal investigator of the study. “Our study demonstrates that the sensitivity of glioblastoma to a drug is influenced not only by the content of its DNA sequences, but also by how the DNA sequences are organized and interpreted by the cell.” The team of scientists, led by Chen, used a method called comparative gene signature analysis to study the genetic profiles of tumor specimens collected from approximately 900 glioblastoma patients. …
Cancer is deadly in large part due to its ability to metastasize, to travel from one organ or tissue type to another and malignantly sprout anew. The vast majority of cancer deaths are associated with metastasis. In breast cancer, a process called “epithelial to mesenchymal transition” aids metastasis…
The multi-institutional group, led by scientists at Cancer and Blood Diseases Institute (CBDI) at Cincinnati Children’s Hospital Medical Center, publish their results in the journal’s online edition on Aug. 24. The researchers suggest their laboratory findings in mouse models of the disease could lead to a more targeted and effective molecular therapy that would also reduce the harmful side effects of current treatments, which include chemotherapy, radiation or surgery. “Although current treatments improve survival rates, patients suffer severe side effects and relapse tumors carry mutations that resist treatment,” said lead investigator Q. …
