The question becomes who is invading whom — do cancer cells invade the basement membrane or do some fibroblasts help invading cancers? Researchers at the Institut Curie in Paris now say that they have evidence of a coordinated attack on the basement membrane by cancer cells in situ and CAF cells in the extracellular matrix that begins long before the actual translocation of cancer cells. …
The findings — to be presented in poster form on December 6, from 5:30 PM to 7:30 PM, in the West Building, Level 1 — may ultimately guide doctors in deciding which therapies are best for individual patients with myeloma, the study authors say. The study focused on exosomes, tiny sacs that cells release into the bloodstream as a way of communicating with other cells. The exosomes contain microRNA molecules, fragments of RNA that help control the activity of genes…
The new report by Cancer Research UK and the National Cancer Intelligence Network reveals the difference in rates of surgery across 21 different cancer types. While many factors might be at play — frailty, suffering more than one illness, being diagnosed at a late stage, patients choosing not to undergo surgery — these statistics paint a worrying picture. Younger cancer patients were more likely to have surgery for 19 cancer types, with the largest differences between age groups seen in kidney and ovarian cancers. …
The current study results revolve around proteinases, enzymes that break down proteins as part of cellular life. Matrix metalloproteinases or MMPs specifically target the extracellular matrix, the non-cell, structural framework within tissues. Beyond that role, the new study found that one member of this family, MMP-2, has another signaling role related to the human immune system. It may shift a set of cells to become part of immune response that accelerates healing in some cases, but may worsen inflammatory disease in others. …
The findings are particularly important for men with longer life expectancies because the therapy exposes them to more adverse side effects, and it is associated with increased risk of death and deprives men of the opportunity for a cure by other methods. The research study has been published online in European Urology.� The focus of the new study is androgen deprivation therapy (ADT), in which an injectable or implanted medication is used to disrupt the body’s ability to make testosterone. ADT is known to have significant side effects such as heart disease, diabetes, increased weight gain and impotence; however a growing body of evidence suggests ADT may in fact lead to earlier death…
Published online Dec. 5 in PLOS ONE, the scientists say the agent, YK-4-279, is the first drug targeted at the chromosomal translocations found in about half of prostate cancer cells. These translocations occur when two normal genes break off from a chromosome and fuse together in a new location. …
The results of their study appear online in the journal Nature today. “Treatment for advanced bladder cancer is limited to surgery and chemotherapy…
Q: How was the study set up and what factors were examined? …
Traditionally used to detect cancer, PET imaging shows how organs and tissues are functioning. When used with X-rays generated from CT scans, PET scans provide a more complete picture of the area of the body being examined…
The numbers add up to a strong economic case to invest in services to support mums to carry on breastfeeding, they conclude. In common with many other high income countries, breastfeeding rates in the UK are low, and to find out if boosting these could cut healthcare costs by improving mother and child health, the researchers focused on five priority diseases…
