Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

Researchers identify 32 genetic regions associated with osteoporosis, fracture

Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have been identified by a large, worldwide consortium of researchers, including Stanford Prevention Research Center chief John Ioannidis, MD, DSc. Variations in the DNA sequences in these regions confer either risk or protection from the bone-weakening disease. Many, but not all, of the regions encode proteins involved in pathways known to involve bone health.

Two research studies on genetic components of Alzheimer's

Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics.

New genes may explain individual differences in brain size and intelligence

In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease.

Researchers identify new mechanism by which colon cancer develops

A team of researchers at Case Western Reserve University School of Medicine have identified a new mechanism by which colon cancer develops. By focusing on segments of DNA located between genes, or so-called "junk DNA," the team has discovered a set of master switches, i.e., gene enhancer elements, that turn "on and off" key genes whose altered expression is defining for colon cancers.

The key to treating AML may lie within FTL3 gene mutations

The key to treating one of the most common types of human leukemia may lie within mutations in a gene called FLT3, according to new research led by physician-scientists at the University of California, San Francisco (UCSF) Helen Diller Family Comprehensive Cancer Center.

Researchers discover new class of molecular mutation in breast cancer

Mayo Clinic researchers have discovered a new class of molecular mutation in various forms of breast cancer, a finding that may shed new light on development and growth of different types of breast tumors. Called fusion transcripts, the mutated forms of RNA may also provide a way to identify tumor subtypes and offer new strategies to treat them, investigators say.

First study to show genetic adaptation of human fat metabolism

About 300 000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans. In today's life situation, this genetic adaptation contributes instead to a higher risk of developing disorders like cardiovascular disease.

Study contains warning for obese expectant mother

A new University of Illinois study contains a warning for obese women who are planning pregnancies. Even if they eat a healthy diet when they are pregnant, their babies will develop in an unhealthy environment that places the infants at risk for future health problems.

Researchers discover intra-cellular function of LOXL2 protein

Researchers at the Hospital de Mar Research Institute (IMIM) have discovered that the protein LOXL2 has a function within the cell nucleus thus far unknown. They have also described a new chemical reaction of this protein on histone H3 that would be involved in gene silencing, one of which would be involved in the progression of breast, larynx, lung and skin tumours.

Huntington’s disease may protect against cancer: Study

Dr Jianguang Ji, Lund University, and Skåne University Hospital, Malmö, Sweden, and colleagues investigated data from the Swedish Cancer Registry. Researchers analyzed Swedish hospital data from 1969 to 2008. They found 1,510 patients with Huntington's disease. During the study period, 91 of those patients subsequently developed cancer. The authors said that was 53% lower than the levels expected for the general population.

Niceness is gene deep

Researchers at the University of Buffalo and University of California, Irvine, found a connection between people being nice and versions of receptor genes for two hormones, oxytocin and vasopressin, that have been associated with niceness in past studies.

ALL induction treatment failure should not be an automatic indication for bone marrow transplant

International study that included St. Jude Children's Research Hospital reports some young acute lymphoblastic leukemia patients who fail induction therapy can achieve high cure rates without bone marrow transplantation.

Scientists discover mutation limited to brain tissue that causes HMG

Scientists have discovered a mutation limited to brain tissue that causes hemimegalencephaly (HMG), a condition where one half of the brain is enlarged and dysfunctional, leading to intellectual disability and severe epilepsy.

Hi-C sequencing decodes 3-D structure of DNA folds in chromosomes

Chromosomes are strands of DNA that contain the blueprint of all living organisms. Humans have 23 pairs of chromosomes that instruct how genes are regulated during development of the human body. While scientists have developed an understanding of the one-dimensional structure of DNA, until today, little was known about how different parts of DNA are folded next to each other inside the nucleus.

Transcription factors do not act like an 'on-off' switch

A UNC-led team of scientists has now shown that transcription factors don't act like an 'on-off' switch, but instead can exhibit much more complex binding behavior.

Austrian scientists challenge the clinical relevance of the term “basal-like” breast cancer subtype

Not all breast cancers are the same. Different types can mean different prognoses for the patient, and a different kind of treatment may be adequate. But how to classify tumors? Are molecular classification methods reliable? Mohammad Ali Lavasani and Farid Moinfar from the Unit of Breast and Gynecologic Pathology at the Medical University of Graz, Austria give a critical review of the literature with focus on “basal-like” carcinoma.

CLYD gene serves as crucial negative regulator in pulmonary fibrosis

An international team of researchers led by Georgia State University scientists have found a key component in the pathological process of pulmonary fibrosis, a fatal disease for which there is currently no cure.

Botanical formula controls aggressive human prostate tumors in mice

A non-toxic, botanical formula controls aggressive human prostate tumors in mice, according to a peer-reviewed study in the The International Journal of Oncology. Researchers at Indiana University, Methodist Research Institute, showed the prostate formula significantly suppresses tumor growth in aggressive, hormone-refractory (androgen-independent) human prostate cancer cells.
