New model to study, find ways to target rare tumor Angiosarcoma or lymphangiosarcoma, a rare malignant tumor of the blood or lymphatic vessels, has no cure, say cancer researchers. However, through recent study, a team has found a new target that could lead to therapies for this rare type of tumor.
Intelligent gel attacks cancer A new injectable “bio gel” is effective in delivering anti-cancer agents directly into cancerous tumours and killing them. This technology has already been successfully tested in the laboratory. If it works in patients, the therapy could one day revolutionize treatment for many forms of cancer
Personalized drug screening on horizon for multiple myeloma patients A personalized method for testing the effectiveness of drugs that treat multiple myeloma may predict quickly and more accurately the best treatments for individual patients with the bone marrow cancer. The process also may aid patients with leukemia or lymphoma
Portable device can quickly test for sickness-causing toxins in shellfish Mussels, oysters, scallops and clams might be ingredients for fine cuisine, but they can also be a recipe for diarrhetic shellfish poisoning That's a gastrointestinal illness people can get if those tasty morsels contain marine toxins. Now, researchers are reporting the development of a portable, inexpensive device that can quickly and easily screen freshly caught shellfish for these substances
Study lays groundwork for blood test to aid in the detection and monitoring of myeloma Only 5 percent of myeloma cases are stage I when diagnosed. One reason may be the lack of good routine screening tests to identify patients who will progress to myeloma. A new study has found that abnormal levels of microRNAs (miRNAs) detected in the bone marrow of multiple myeloma patients may also be detectable in peripheral blood, and their measurement may be a way to both mark myeloma onset and track its progression from earlier asymptomatic stages.
New test detects all viruses that infect people, animals A new test detects virtually any virus that infects people and animals, according to new research. The new test could be used to detect outbreaks of deadly viruses such as Ebola, Marburg and severe acute respiratory syndrome (SARS), as well as more routine viruses, including rotavirus and norovirus, both of which cause severe gastrointestinal infections
Elabela identified as potential hormone for regenerative medicine A hormone is found to be critical in promoting growth of human embryonic stem cells, paving the way for improved regenerative medicine and cell-based therapies
Hybrid cells cause chaos around cancers Like all cells, those in tumors need access to the body's fine network of blood vessels to bring them oxygen and carry away waste. Tumors have learned to game the process called angiogenesis in which new vessels sprout from existing ones, like branches from a tree. Now, researchers have built a simulation to understand how cancerous tumors manipulate blood-vessel growth
Multiple myeloma hides in bones like a wolf in sheep's clothing Multiple myeloma uses a trick akin to a wolf in sheep’s clothing to grow in and spread to new bone sites. By overexpressing Runx2, a gene that normally is a master regulator of bone formation, the cells of this largely incurable cancer produce proteins that mimic the normal bone-resident cells.
New technique for precise light-activated chemotherapy drugs A new technique that uses light to activate chemotherapy drugs in specific cells shows promise as a way to improve the effectiveness of cancer therapies while preventing severe side effects, according to a study. The approach could be used to treat a range of tumors with unprecedented precision by making existing cancer drugs sensitive to light
Super graphene can help treat cancer Silver is often used as a coating on medical equipment used for chemotherapy. The problem is that this silver coating can break down drugs. Now, researchers have found a graphene coating that will help boost chemotherapy's effects.
Cell structure discovery advances understanding of cancer development A cell structure has been discovered that could help scientists understand why some cancers develop. For the first time, a structure called 'the mesh' has been identified which helps to hold together cells. This discovery changes our understanding of the cell's internal scaffolding.
What makes cancer cells spread? New device offers clues Cancer becomes deadly when it spreads, or metastasizes. Why do some cancer cells break away from a tumor and travel to distant parts of the body? A team of oncologists and engineers teamed up to help understand this crucial question.
Biomarker may boost ovarian cancer chemotherapy response A molecule that helps control gene expression may play a role in controlling chemotherapy resistance among patients with the most common form of ovarian cancer. Chemoresistance is a major challenge in cancer treatment and this study may provide a means to overcome resistance.
