New drug could help in battle against cervical cancer

A Cancer Research UK-funded UK study led by researchers at the University of Leicester, with key collaborators from the Universities of Glasgow, Manchester and Edinburgh, has discovered that adding the investigational agent cediranib, which has been developed by the multinational pharmaceutical and biologics company AstraZeneca, to standard chemotherapy may be beneficial for patients with metastatic or recurrent cervical cancer and could pave the way for future treatment of the disease. Professor Paul Symonds from the Department of Cancer Studies and Molecular Medicine at the University of Leicester and a consultant at Leicester’s Hospitals, explained: “Cancers develop their own blood supply and cancers of the cervix with a well-developed blood supply can have a particularly bad outcome for the patient. “One of the substances which increase new blood vessels in cervical cancer is Vascular Endothelial Growth Factor (VEGF). The experimental drug cediranib blocks the receptor for VEGF in the cancer, potentially limiting its growth in the body. …

New hope for potential prostate cancer patients

The only place in the Southeast offering the MRI-US image fusion technique is at the University of Alabama at Birmingham Program for Personalized Prostate Cancer Care. It is estimated that 2014 will see more than 240,000 new cases of prostate cancer, and more than 29,000 deaths from the disease, according to the National Cancer Institute. Jeffrey Nix, M.D., along with colleague Soroush Rais-Bahrami, M.D., both assistant professors in the UAB Department of Urology, studied the MRI-US image fusion as fellows at the NCI. Nix and Rais-Bahrami are two of a select few urologists in the United States trained to utilize this technology; together they have five years’ experience using this approach. …

Cancer exosome ‘micro factories’ aid in cancer progression — ScienceDaily

“Exosomes derived from cells and blood serum of patients with breast cancer, have been shown to initiate tumor growth in non-tumor-forming cells when Dicer and other proteins associated with the development of miRNAs are present,” said Raghu Kalluri, M.D., Ph.D., chair of the department of cancer biology at MD Anderson. “These findings offer opportunities for the development of exosomes-based biomarkers and shed insight into the mechanisms of how cancer spreads.” Exosomes are small vesicles consisting of DNA, RNA and proteins enclosed in a membranes made up of two lipid layers…

Silencing the speech gene FOXP2 causes breast cancer cells to metastasize

Now a research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has identified an unexpected link between a transcription factor known to regulate speech and language development and metastatic colonization of breast cancer. Currently described online in Cell Stem Cell, the new findings demonstrate that, when silenced, the FOXP2 transcription factor, otherwise known as the speech gene, endows breast cancer cells with a number of malignant traits and properties that enable them to survive — and thrive. “We have identified a previously undescribed function for the transcription factor FOXP2 in breast cancer,” explains senior author Antoine Karnoub, PhD, an investigator in the Department of Pathology at BIDMC and Assistant Professor of Pathology at Harvard Medical School. “We have found that depressed FOXP2 [a member of the forkhead family of transcriptional regulators] and elevated levels of its upstream inhibitor microRNA 199a are prominent features of clinically advanced breast cancers that associate with poor patient survival.” Karnoub’s lab investigates the roles that mesenchymal stem cells (MSCs) play in the development and metastasis of breast cancer…

Hidden subpopulation of melanoma cells discovered

The research, published in the journal Nature Communications, provides evidence for how these particular melanoma cells help tumors resist drugs designed to block blood vessel formation. “For a long time the hope has been that anti-angiogenic therapies would starve tumors of the nutrients they need to thrive, but these drugs haven’t worked as well as we all had hoped,” said Andrew C…

With three first-in-human trials, therapeutic stem cell science takes a bold step

The procedure, conducted on Sept. 30 under the auspices of the Sanford Stem Cell Clinical Center at UC San Diego Health System and in collaboration with Neuralstem, Inc., a Maryland-based biotechnology firm, is the first of four in the Phase I clinical trial. …

Patients treated with radiation therapy who have tumors in left breast have comparable overall survival to those with tumors in right breast –…

Studies have shown that breast cancer patients treated with radiation therapy have improved local-regional recurrence, and breast cancer-specific survival after breast-conserving surgery and overall survival (OS) after mastectomy. Long-term follow-up of historic radiation therapy trials for breast cancer has demonstrated a potential increase in cardiac mortality. However, these studies used earlier modes of radiation therapy including Cobalt and orthovoltage radiotherapy, and did not employ CT-based planning, which allows for greater cardiac avoidance. Three recent studies suggest that cardiac mortality has not been greater for patients treated for left-sided breast cancer since the 1980s, when techniques allowing for greater cardiac avoidance became more commonplace[1-3]. …

Discovery of cellular snooze button advances cancer, biofuel research

The discovery that the protein CHT7 is a likely repressor of cellular quiescence, or resting state, is published in the current issue of the Proceedings of the National Academy of Sciences. This cellular switch, which influences algae’s growth and oil production, also wields control of cellular growth — and tumor growth — in humans…
