A step closer to understanding how BPA may promote breast cancer growth
3/11/2014
Subhrangsu Mandal, associate professor of chemistry/biochemistry, and Arunoday Bhan, a PhD student in Mandal's lab, looked at a molecule called RNA HOTAIR. HOTAIR is an abbreviation for long, non-coding RNA, a part of DNA in humans and other vertebrates.
Leukemia gene mutation linked to new childhood growth disorder
3/10/2014
New research led by the Institute of Cancer Research in the UK has discovered that a gene mutation associated with leukemia may be the cause of a newly described condition that affects the growth and intellectual development of children.This is according to a study recently published in the journal Nature Genetics.
Protein synthesis studied in stem cells for the first time
3/10/2014
A new breakthrough in stem cell research has occurred, thanks to scientists at the Children's Medical Center Research Institute at UT Southwestern Medical Center in Dallas, Texas. The researchers claim that protein synthesis - an essential biological process - can be studied in adult stem cells. This is something that scientists have been previously unable to accomplish.
Only 25% of ovarian cancer cases diagnosed in Stage I
3/10/2014
During ovarian cancer awareness month, analysis from global independent analyst firm, Datamonitor Healthcare, has revealed that just 25% of ovarian cancer cases are diagnosed in Stage I despite it being the fourth most common cancer among women.
UV light accelerates melanoma cancer cells that creep along the outside of blood vessels
3/10/2014
Based on the pioneering work of Dr. Claire Lugassy and Dr. Raymond Barnhill at UCLA's Jonsson Comprehensive Cancer Center, a new study provides additional support for a process by which melanoma cells, a deadly form of skin cancer, can spread throughout the body by creeping like tiny spiders along the outside of blood vessels without ever entering the blood stream, and that this process is...
Mutations in leukaemia gene linked to new childhood growth disorder
3/10/2014
Mutations in a gene associated with leukaemia cause a newly described condition that affects growth and intellectual development in children, new research reports.A study led by scientists at The Institute of Cancer Research, London, identified mutations in the DNA methyltransferase gene, DNMT3A, in 13 children.
Targeted therapy with erlotinib may prolong survival of patients with cervical cancer
3/10/2014
A new clinical study has found that erlotinib, a targeted antitumor agent, has promising potential to improve treatment for cervical cancer. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the results indicate that larger trials are warranted to determine whether the drug should become part of standard therapy for women with the disease.
7-Tesla MRI scanner allows even more accurate diagnosis of breast cancer
3/10/2014
Taking part in a recent study, scientists at the MedUni Vienna have demonstrated for the first time worldwide that 7-Tesla ultra-high-field magnetic resonance imaging (MRI) can be used for clinical applications in patients with breast tumours. This may in future facilitate even more accurate diagnosis of breast cancer.
Device to prevent cancer patient hair loss being tested at UCLA
3/10/2014
Research physicians at UCLA's Jonsson Comprehensive Cancer Center have begun a clinical trial on a new device that promises to reduce hair loss of patients receiving chemotherapy for breast cancer. The apparatus, called the DigniCap® System, works by cooling the patient's scalp. The clinical trial will be led at UCLA by Dr.
Enzyme controls transport of genomic building blocks
3/10/2014
Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers show how an enzyme controls reliable and high-speed delivery of histones to DNA copying hubs in our cells.
