Certain mutated cells continue DNA replication process even after drug treatment

Certain mutated cells keep trying to replicate their DNA - with disastrous results - even after medications rob them of the raw materials to do so, according to new research from USC.

Pachytene piRNAs play an essential role in protecting post-meiotic germ cells

Passing one's genes on to the next generation is a mark of evolutionary success. So it makes sense that the body would work to ensure that the genes the next generation inherits are exact replicas of the originals.

Review: Even very low radiation levels are harmful to life

Even the very lowest levels of radiation are harmful to life, scientists have concluded in the Cambridge Philosophical Society's journal Biological Reviews.

Study describes role of TFIIB protein in helping cells repair DNA damage

In a new study, University at Buffalo scientists describe the role that a protein called TFIIB plays in helping cells repair DNA damage, a critical function for preventing the growth of tumors.

Green tea may reduce risk of digestive system cancers among women

Women who drink green tea may lower their risk of developing some digestive system cancers, especially cancers of the stomach/esophagus and colorectum, according to a study led by researchers from Vanderbilt-Ingram Cancer Center.

Scientists identify mechanism via Top2b enzyme that drives doxorubicin-induced heart damage

Doxorubicin, a 50-year-old chemotherapy drug still in widespread use against a variety of cancers, has long been known to destroy heart tissue, as well as tumors, in some patients.

Lipid droplets play an unexpected role in embryo development

Histones are proteins needed to assemble DNA molecules into chromosomes. They have long represented a classic balancing act in biology; too few histone molecules result in DNA damage, while too many histones are toxic to the cell. New research at the University of Rochester is causing a fundamental shift in the concept of histone balance and the mechanism behind it.

DNA damage response contains previously unknown components: Study

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida; Duke University; Johns Hopkins University; the Brazilian National Cancer Institute; and the Rio de Janeiro Federal Institute of Education, Science and Technology have discovered that an intricate system to repair DNA damage called the "DNA damage response" (DDR) contains previously unknown components, including proteins that could be targeted as sensitizers for chemotherapy.

Salk findings on cold virus proteins may spur new cancer treatments

Cold viruses generally get a bad rap----which they've certainly earned----but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ally in the fight against cancer.

Researcher uncovers mechanisms involved in prognosis of acute myeloid leukemia

When patients suffering from Acute Myeloid Leukemia (AML) express high levels of the gene, MN1, an already aggressive leukemia is accelerated and shortens survival time. While that's a known fact, the mechanisms involved aren't well understood which is why a Wake Forest Baptist Medical Center researcher decided to take a closer look.

Sun protection: an interview with Jane Hanrahan

UV radiation is a form of energy being transmitted. Sunlight is main source of UV radiation, although manmade sources also exist, such as the lamps used in sunbeds. At the earth’s surface sunlight consists of approximately 2 percent UV light, 47 percent visible light and 51 percent IR light.

PARP-1 plays a major role in controlling AR function in prostate cancer patients

A newly discovered function of PARP-1 could be the key to more effective therapeutics to treat advanced prostate cancer patients, a recent preclinical study published in Cancer Discovery by Jefferson's Kimmel Cancer Center researchers suggests.

Skin's outmost layer is the first line of defense against UV radiation

Reinhold Dauskardt, PhD, of Stanford's Department of Materials Science and Engineering has been studying skin for years. But when he sent his students to look for data on the mechanical properties of skin, they came back empty-handed. A lot was known about skin structure and disease, but few papers actually talked about its mechanical function - its ability to stretch and resist tension without tearing.

Treatment with Lfcin4-14 reduces DNA damage in colon cancer cells exposed to UV light

Milk consumption has been linked to improved health, with decreased risks of diabetes, metabolic syndrome, and colon cancer. A group of scientists in Sweden found that lactoferricin4-14 (Lfcin4-14), a milk protein with known health effects, significantly reduces the growth rate of colon cancer cells over time by prolonging the period of the cell cycle before chromosomes are replicated. In a new study, investigators report that treatment with Lfcin4-14 reduced DNA damage in colon cancer cells exposed to ultraviolet (UV) light.

Synthetic hybrid molecules more effectively tackle chemo-resistant cancers

When Linda Tuttle was diagnosed with breast cancer, she never imagined her experience would inspire her colleagues to design new treatments to tackle the disease.

Zinc deficiency mechanism associated with many health problems, aging

A new study has outlined for the first time a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes.

Genetic profile predicts postradiation erectile dysfunction

Scientists have identified a group of genetic markers that can predict the risk for erectile dysfunction after radiotherapy for prostate cancer.

RRM2 may be a facilitating factor in colorectal cancer and UV-induced DNA damage repair

Colorectal cancer (CRC) is the leading cause of cancer-related death worldwide. In addition, the incidence and mortality rates of colorectal cancer are on the rise. Recently, metabolic genes have received increasing and specific attention due to their potential role in carcinogenesis.

BGI Tech achieves whole exome sequencing analysis of total degraded DNA from FFPE samples

BGI Tech Solutions Co., Ltd., a subsidiary company of BGI, announced today that they have achieved whole exome sequencing analysis of total degraded DNA as low as 200 ng from formalin fixed paraffin embedded (FFPE) samples.
