Researchers found a genetic connection between permanent hair dye use and bladder cancer risk, particularly among women with certain slow genes. The study suggests that exposure to hair dyes increases the risk of bladder cancer, likely due to the presence of carcinogenic arylamines.
Researchers at the University of Michigan have identified a gene, AMACR, which triggers production of a specific enzyme involved in fat metabolism. The protein is detected in over 95% of localized prostate cancer cells and shows high sensitivity and selectivity ratings for diagnostic purposes.
Korenberg's work enables doctors to predict treatment outcome and adverse reactions using gene-expression profiles, bringing personalized medicine closer. The advance could lead to more effective treatments and minimize hospitalizations due to drug-induced side effects.
Research reveals wheat contains antioxidants that combat free-radicals, potentially fighting cancer, diabetes, and heart disease. Modified wheat strains with high levels of these antioxidants could be created to fight cancer through dietary inclusion.
Researchers found that plants inherit traits from factors outside of genes, such as DNA modification and packaging, which can be passed on to offspring. The study suggests a cost of resistance in plants, where hyperactive defense systems lead to physical damage despite low disease threat.
A new study reveals a reliable method for identifying proximal colorectal cancers through faecal DNA analysis. The test, which detected mutations in the BAT26 gene, showed zero false positives and high specificity.
A new stool test developed by Johns Hopkins Medicine can detect the earliest, curable stages of colon cancer with high accuracy. The test uses a technology called Digital Protein Truncation to identify a key genetic marker of the disease, and has been shown to reliably detect cancers at an early stage, yielding no false positives.
Researchers found that Egfr signaling is essential for intestinal tumor formation in mice, with 90% fewer polyps developing in one group. The study suggests a potential treatment approach using Egfr inhibitors for advanced colorectal cancers.
Researchers at Cold Spring Harbor Laboratory have developed a new technique for carrying out genetic analysis directly in mammalian cells, enabling them to switch off or switch on genes in mouse cells. This ability allows researchers to infer gene function, identify potential cancer therapies, and discover new properties in cells.
Researchers have discovered that specific cellular mechanisms confer resistance to cancer in rats, allowing them to develop pre-cancerous lesions but then return to normal. The study aims to identify genes involved in this resistance, which could lead to breakthroughs in human cancer prevention and therapy.
Researchers found that the most accurate method of detecting genetic mutations, direct nucleotide sequence analysis, is also the most expensive and labor-intensive. This method was used correctly to identify all previously identified mutations, while other methods, such as SSCP and CSGE, failed to detect over 20% of the mutations.
Researchers at Thomas Jefferson University identified a possible link between APC gene mutation and colon cancer, suggesting survivin's role in preventing programmed cell death. The study found that abnormal regulation of survivin may contribute to the development of colon cancer by allowing stem cells to overpopulate.
Researchers at Johns Hopkins have developed a potential new screening test for prostate cancer by measuring the level of GSTP1 methylation in tissue samples. High levels of methylation were detected in 91.3% of early-stage cancers and 53.6% of precancerous lesions, suggesting its potential as an early diagnostic marker.
Arsenic inhibits transcription of the hTERT gene, which in turn inhibits telomerase, causing genetic instability that may lead to cancer in healthy cells. The study's findings also have implications for developing more effective chemotherapy treatments for leukemia.
Researchers stress the need for updated informed consent models for population-based genetic research. Older models may not adequately address risks and benefits, particularly in studies involving common gene variations with smaller disease impacts.
Dana-Farber Cancer Institute scientists have developed a new biological classification of adenocarcinomas using miniaturized gene chips. The technique groups tumors by their genetic 'signatures', which can capture distinctive patterns of active and inactive genes, allowing for more accurate diagnoses and treatments.

Their findings have significant implications for our understanding of intelligence, anxiety, and climate change.
A study by Ohio State University researchers reveals minute genetic changes in normal colonic tissue that may signal later development of certain types of colon cancer. The changes, which occur through hypermethylation, appear to be age-related and associated with microsatellite instability.
Researchers at Massachusetts General Hospital have found a gene called archipelago, or ago, involved in destroying the protein cyclin E. This regulation is crucial for cell division, and irregularities may lead to uncontrolled growth and cancer.
Researchers used gene therapy to treat mice with beta-glucuronidase deficiency, a condition that affects approximately 1 in 5,000 babies. The treatment showed promise by improving symptoms for up to a year, but six mice eventually developed cancer, raising questions about the long-term safety of this approach.
Researchers have uncovered evidence suggesting that genetic changes leading to breast cancer occur first in epithelial cells of breast tissue. LOH analysis reveals frequent mutations in both epithelial and stromal cells, indicating a multi-step process.
A large population-based study in Nordic countries found no increased cancer risk for siblings of children with common non-inheritable cancers. Siblings younger than 10 years were at higher risk, but this decreased with age. The study suggests that childhood cancer is not a predictor of increased cancer risk in siblings.
UCLA researchers have discovered a unique gene modification that may be the cause of certain types of lymphoma. The discovery, which involves DNA methylation, could lead to new treatments for these types of cancer.
The grant aims to continue research into breast, prostate, and colorectal cancer's genetic basis using the Hawaii/Los Angeles Multiethnic Cohort Study. The expanded funding will enable the collection of blood samples from over 215,000 participants, providing insights into cancer risks and susceptibilities.
Researchers have isolated a new version of a herpesvirus that kills cancer cells but spares normal tissue, dramatically reducing prostate cancer tumors in mice. The new virus contains an extra genetic mutation that enables more robust reproduction and prevents the cell from mounting a response to stop viral replication.
A new study confirms previous findings that hair color, number of moles on the legs, and history of sunburn are risk factors for malignant melanoma. The study also found that use of sunbeds and other tanning devices is associated with an increased risk of the disease.
