Similar genetic origins possible for schizophrenia and bipolar disorder

...dividuals with neither disorder. "The expression profiles of most known oligodendrocyte-specific and myelin-associated genes were greatly reduced, and several transcription factors known to coordinate myelin gene expression showed corresponding changes," says Yolken. "These results provide strong evidence f...

Using GPR to estimate tree root biomass

Chemical change may help predict seriousness and course of some cancer

...neously. The researchers examined the methylation profiles of RASSF1A genes taken from 37 primary breast tumors, seven breast-cancer cell lines and 10 samples of normal breast tissue. Specifically, they measured methylation levels at 19 sites spanning two adjoining regions of the gene: the promoter region, w...

Temple study identifies molecular mechanisms that may assist gene in blocking lung cancer

...lung cancer," says Giordano. "The gene expression profiles provided by microarray analysis will someday help tailor specific gene therapies to individual patients." Lung cancer is the leading cause of cancer death worldwide and is usually diagnosed at an incurable stage, most likely due to the absence of eff...

...mental chemicals induce in the genetic and protein profiles of the mammary gland. "This research should provide clues about the pathways that are responsible for modulating the susceptibility or resistance of the mammary tissue to carcinogenesis," explained Russo. Dr. Mary Wolff and her colleagues at Mt. Si...

NSF awards four-year, $3.9 million grant to plant biology team led by University of Georgia

... permit the simultaneous examination of expression profiles of 15,000 to 30,000 genes. Among a number of goals, the UGA research project will seek to improve LM for use on maize shoot apical meristems and then make the information available on a project web site. Profiles of global gene expression in the SAM...

PTEN and prostate cancer--the devil is in the doses

...o allow more accurate assessments. These molecular profiles can also help researchers design targeted, more efficient prostate cancer treatments. For example, if prostate tissue is hypersensitive to PTEN in humans--which the results suggest may be the case, since male mice with only 30% of normal PTEN levels ...

UB researchers show first evidence of pharmacogenomic differences in patients' responses to MS drug

...ex gene-expression modulation. The pharmacodynamic profiles indicate that changes in the gene expression occur as early as 1-4 hours of injection and that these changes modulate the immune system. "Our results support the premise that gene expression profiling using microarray techniques and studying the pha...

Ethical guidelines needed before 'nutrigenomic' groceries come to market

... dietary changes. Tests to determine genetic risk profiles are currently being offered by a small number of companies in Canada, the United States and the United Kingdom. At least two companies say the tests will help people choose diets that will improve their health. "In order to ensure that only the best...

Clock cells, tumor suicide, tailored therapies among subjects of AACR-NCI-EORTC Conference

...f head and neck cancer by examining the biological profiles of different tumors, which affect their responsiveness to radiotherapy. Scientists hope eventually to be able to tailor cancer therapy specifically to the biological behavior of an individual patient's tumor. "This is the foremost annual meeting ...

Gliomas' 'molecular fingerprint' predicts how aggressive tumor will be

... the researchers used mass spectrometry to develop profiles of proteins active in 60 human brain samples. These included 19 samples of normal tissue and 15 grade II, 11 grade III and 15 grade IV gliomas. The researchers identified more than 200 potential molecular markers that distinguished normal from mali...

A first glance at global genetic networks

...re genetic networks. Analyzing the gene expression profiles of six distantly related organisms--bacteria, yeast, plant, nematode, fruitfly, and human--the researchers found that functionally related genes were co-expressed in each species. The most strongly conserved sets of co-expressed genes were associated...

Researchers unlock key secrets showing how tumors hide from immune system

...nology to study the characteristic gene expression profiles or "molecular signatures" of certain genes that are regulated by the STAT. Scientists suspect that many genes that are directly or indirectly regulated by Stat3 may contribute to cancer, and they are working to develop new drugs based on inhibiting S...

Predicting progression of common cancers
