“Exosomes are minuscule membrane vesicles — or sacs — released from most, if not all, cell types, including cancer cells,” said Yong Zeng, assistant professor of chemistry at the University of Kansas. “First described in the mid-’80s, they were once thought to be ‘cell dust,’ or trash bags containing unwanted cellular contents. …
Sonic Hedgehog belongs to a family of proteins that gives cells the information needed for the embryo to develop properly. It also plays a significant role in tumorigenesis, the process that transforms normal cells into cancer cells…

Assessing if and how far breast cancer has spread throughout the body is what doctor’s refer to as staging. …
The San Diego-based company has developed an experimental treatment, called ZMapp, which contains antibodies manufactured in plants. …
“Anorexia and cachexia are among the most troubling and distressing symptoms of advanced cancer, for both patients and their families,” says the study’s principal investigator, Dr Jennifer Temel from the Department of Medicine, Massachusetts General Hospital, Boston, USA. Symptoms of the wasting syndrome can include a loss of weight and muscles, together with fatigue, weakness, and loss of appetite. The condition is very common in patients with advanced lung cancer. Anamorelin aims to address the symptoms by mimicking the effects of the so-called “hunger hormone” ghrelin, which is secreted by the stomach…
CLEOPATRA was a pivotal phase III study where researchers evaluated the safety and efficacy of pertuzumab, trastuzumb and chemotherapy in 808 patients with previously untreated HER2-positive metastatic breast cancer. …
“Oncology is an exceptionally rewarding career, but it can be demanding and stressful at times,” said Dr Susana Banerjee, lead author of the study and a consultant medical oncologist at The Royal Marsden NHS Trust in London, UK. “Oncologists make complex decisions about cancer management, supervise the use of toxic therapies, work long hours, and continually face patients suffering and dying,” she said…
The researchers base their findings on almost 93,000 women taking part in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) in England. The women were all aged over 50, had gone through the menopause, and had no known breast cancer when they entered the study between 2005 and 2010. At enrolment they provided detailed information on height and weight (BMI); reproductive health; fertility; family history of breast and ovarian cancer; and use of hormonal contraceptives and HRT, all of which influence breast cancer risk. They were also asked about their current skirt size, and what this had been in their 20s. …
As cancer cells divide, they accumulate random mistakes (mutations). This process creates new versions of proteins, some of which are recognized as foreign invaders by immune cells called T cells, prompting the cells to attack and eliminate the cancer cells. With our current ability to identify all of the mutations in a patient’s cancer and to understand which protein sequences can be recognized by T cells, scientists can now predict which mutations will result in new T cell targets (called “neoepitopes”)…
