Stopping cholesterol drugs may be associated with increased risk of Parkinson’s

The current study involved 43,810 people in Taiwan who were taking statins and did not have Parkinson’s disease. Taiwan’s compulsory national health insurance program reimbursement policy requests that doctors stop prescribing statins once the patient’s cholesterol reaches the treatment goal, which is contrary to standard treatment in the United States. "This policy allowed us to see whether there was any difference in the risk of Parkinson’s in people who stopped taking statins compared to the ones who kept taking them," said study author Jou-Wei Lin, MD, PhD, of National Taiwan University in Taipei. …

Large study reveals increased cancer risks associated with family history of the disease

The research, published in the leading cancer journal Annals of Oncology today (Thursday), provides a comprehensive picture of the risk of developing various different types of cancer in families where there is a history of the disease, and is one of the few large studies of this kind that takes into account other important factors, such as individual characteristics and lifestyles, that could affect the degree of risk as well. Results from the study supported known associations, such as the increased risk of developing the same cancer as a close relative, and the 1.5-fold increased risk of breast cancer in women with a history of colorectal cancer in the family. However, the study also found a 3.3-fold increased risk of developing oral and pharyngeal cancer among people who had a first-degree relative with cancer of the larynx, and a four-fold increased risk of cancer of the gullet (esophageal cancer) where a first-degree relative had oral or pharyngeal cancer. If a first-degree relative had breast cancer, female family members had a 2.3-fold increased risk of ovarian cancer…

Keeping centrioles in check to ensure proper cell division

Their results are published in the journal Current Biology today. Centrioles — orchestrators of cell division When our cells divide, their genetic material — in the form of X-shaped chromosomes — is aligned in the middle of the cell and segregated to opposite poles of the cell by a spindle of long tubular fibers, so-called microtubules. The structures that organize the two poles of the spindle in animal cells are called centrosomes…

Gene that may stop the spread of breast cancer identified

This finding, published in Cancer Research, a journal of the American Association for Cancer Research (AACR), may be used to develop therapeutic treatments for patients. "Our research has shown that HGMA2 plays a part in regulating the spread of cancer and could be considered a driver of the process," said Dr. Chada, who was principal investigator of the study. "Further studies could result in the development of therapeutic treatments for patients with breast cancer which could prevent HGMA2’s function, reduce the spread of cancer and extend a patient’s life." According to Dr…

Vaccinating boys plays key role in HPV prevention

HPV has been linked to anal, penile and certain types of throat cancers in men. Since the virus is also responsible for various cancers in women, vaccinating boys will play a crucial role in reducing cancer rates across the sexes. "HPV is the single most common sexually transmitted infection," says Newman, Canada Research Chair in Health and Social Justice. …

Flip of mitotic spindle has disastrous consequences for epithelial cells

Stowers Institute for Medical Research Associate Investigator Matt Gibson, Ph.D., and his team use simple animal systems like fruit flies and sea anemones to investigate how epithelial cells maintain order while getting jostled by cell division. New findings from his lab published in the July 21 advance online issue of Nature demonstrate that the way the mitotic spindle — the machinery that separates chromosomes into daughter cells during cell division — aligns relative to the surface of the cell layer is essential for the maintenance of epithelial integrity. It also hints at a surprising way that cells initiate a gene expression program seen in invasive cancers when that process goes awry. The study employs live imaging of fruit fly imaginal discs, simple larval tissues that ultimately give rise to the adult wing…

Missing piece of pediatric cancer puzzle found

In a study published in the July issue of the Proceedings of the National Academy of Sciences, researchers found a missing piece of the pediatric cancer puzzle. Changxian Shen, PhD, senior research associate at the Center for Childhood Cancer and Blood Diseases at The Research Institute at Nationwide Children’s Hospital, and Peter Houghton, PhD, director of the center, may have identified one mechanism behind the early development of some pediatric solid tumors — as well as a target for future pediatric cancer therapies…

New plan of attack in cancer fight: Two-drug combination, under certain circumstances, can eliminate disease

As described in a paper recently published in eLife, Martin Nowak, a professor of mathematics and of biology and director of the Program for Evolutionary Dynamics, and co-author Ivana Bozic, a postdoctoral fellow in mathematics, show that, under certain conditions, using two drugs in a "targeted therapy" — a treatment approach designed to interrupt cancer’s ability to grow and spread — could effectively cure nearly all cancers. Though the research is not a cure for cancer, Nowak said it does offer hope to researchers and patients alike. "In some sense this is like the mathematics that allows us to calculate how to send a rocket to the moon, but it doesn’t tell you how to build a rocket that goes to the moon," Nowak said…
