Cellular biology of colorectal cancer: New Insight

Lead author Kristi Neufeld, associate professor in the Department of Molecular Biosciences and co-leader of the Cancer Biology program at the KU Cancer Center, has spent the better part of her career trying to understand the various activities of APC, a protein whose functional loss is thought to initiate roughly 80 percent of all colon polyps, a precursor to colon cancer. Neufeld, along with her postdoctoral fellow Maged Zeineldin, undergraduate student Mathew Miller and veterinary pathologist Ruth Sullivan, now reports that APC found in a particular subcellular compartment, the nucleus, protects from inflammation as well as tumor development associated with chronic colitis. Whether APC reaches the nucleus may well affect the ability of intestinal stem cells to produce differentiated cells with specialized functions, Neufeld said. …

Novel gene predicts both breast cancer relapse, response to chemotherapy

Despite advancements in cancer treatment, breast cancer remains the most common cancer among Singapore women. Thirty percent of early breast cancer patients in the world experience relapse due to metastasis, or the spread of cancer cells to other organs in the body. Some patients also do not respond well to chemotherapy…

New ways to treat solid tumors using protein

As EphA3 is present in normal organs only during embryonic development but is expressed in blood cancers and in solid tumors, this antibody-based approach may be a suitable candidate treatment for solid tumors. The researchers from Monash University and Ludwig Cancer Research, in Australia, and KaloBios Pharmaceuticals, in the US, have had their findings published in the journal Cancer Research…

Brain tumors fly under body’s radar like stealth jets, new research suggests

Like a stealth fighter jet, the coating means the cells evade detection by the early-warning immune system that should detect and kill them. The stealth approach lets the tumors hide until it’s too late for the body to defeat them. The findings, made in mice and rats, show the key role of a protein called galectin-1 in some of the most dangerous brain tumors, called high grade malignant gliomas…
