Cancerous brain tumor cells may be at ‘critical point’ between order and disorder, study suggests
Glioblastoma cells are poised near a “critical point” of order and disorder — meaning, the cells possess some form of large-scale coordination throughout the whole tumor that allows them to respond in practical unison to attempts to kill tumor cells, such as chemotherapy or radiation, a study suggests. Researchers say disrupting the large-scale organization of brain tumors may result in more powerful ways to treat and one day eliminate brain tumors.
Exercise increases the number of cancer-destroying immune cells in cancer patients
Two new Finnish studies show that short bouts of light or moderate exercise can increase the number of immune cells in the bloodstream of cancer patients.
Stopping a rare childhood cancer in its tracks
Scientists at Cold Spring Harbor Laboratory (CSHL) have discovered a new drug target for Ewing sarcoma, a rare kind of cancer usually diagnosed in children and young adults. Their experiments show that the cells causing this cancer can essentially be reprogrammed with the flick of a genetic switch.
Surprisingly, these microRNAs boost — rather than dampen — protein expression
microRNAs are thought to suppress protein expression in dividing cells, such as tumor cells. But new research in ACS Central Science shows that some of these molecules can elevate the expression of a particular gene in dividing human cells and in cancer cells, challenging conventional wisdom.
What the mechanical forces behind protein folding can tell us about metastatic cancer
Cells communicate with themselves and their cellular environment through mechanical bonds. This work advances understanding of the role of these forces on proteins as they interact to accomplish their biological functions, including the control of cancer.
Getting Tough on Tuft Cell Lung Cancer
Cold Spring Harbor Laboratory (CSHL) Professor Christopher Vakoc’s team discovered in 2018 a new type of small-cell lung cancer. The cancer originates from cells known as tuft cells.
A Mechanism Is Found Explaining How Cancer Cells Turn Into Normal Harmless Ones
A new research describes how highly proliferative leukemia cells end up becoming normal cells that no longer multiply, by changing the chemical modifications -the so-called epigenetics- of a type of its genetic material: the messenger RNA.
Marine sponge chemical and synthetic derivatives hijack human enzyme to kill cells
A human enzyme converts chemicals produced by marine sponges and related synthetic derivatives into cell-killing compounds, shows a study published today in eLife.
How high-fat diets allow cancer cells to go unnoticed
A high-fat diet increases the incidence of colorectal cancer. Cold Spring Harbor Laboratory Fellow Semir Beyaz and collaborators from Harvard Medical School and Massachusetts Institute of Technology have discovered that in mice, fat disrupts the relationship between intestinal cells and the immune cells that patrol them looking for emerging tumors.
New study shows that different types of cancers are likely to spread to specific areas of the brain
Brain metastasis occurs when cancer in one part of the body spreads to the brain. The lifetime incidence of such metastatic brain tumors in cancer patients is between 20%-45%, research shows.
Novel Assay Finds New Mechanism Underlying Red Blood Cell Aging
A multifaceted microfluidic in vitro assay is helping to identify the role of hypoxia on red blood cell aging via the biomechanical pathways. It holds promise for investigating hypoxic effects on the metastatic potential and relevant drug resistance of cancer cells.
Scientists Find a Pair of Proteins Control Supply Lines That Feed Cancer Cells
In human cancer cell and mouse studies, researchers from Johns Hopkins Medicine have found that a set of proteins work in tandem to build supply lines that deliver oxygen and nutrients to tumors, enabling them to survive and grow. The protein twosome, PADI4 and HIF-1, ramp up their activity under low-oxygen conditions that are typically found in a fast-growing tumor, allowing it to build new blood vessels that feed the cancer’s growth.
