Study identifies genetic factors crucial in acute myeloid leukemia survival for Black patients

Researchers have led a global study that identified molecular predictors of survival among Black patients with acute myeloid leukemia (AML). The study suggests a need to modify current AML risk layers by including ancestry-specific ...

New study identifies genetic changes in brain development that may contribute to schizophrenia

A collaborative study between researchers at the Icahn School of Medicine at Mount Sinai and Harvard Medical School has identified genetic mutations that occur during brain development and may contribute to the development ...

How your skin tone could affect how well your medication works

Skin pigmentation may act as a "sponge" for some medications, potentially influencing the speed with which active drugs reach their intended targets, a pair of scientists report in a perspective article published in the journal ...

Study uncovers mutations and DNA structures driving bladder cancer

How bladder cancer originates and progresses has been illuminated as never before in a study led by researchers at Weill Cornell Medicine and the New York Genome Center. The researchers found that antiviral enzymes that mutate ...

Genetics

Study finds new genetic loci associated with dementia

A research team comprising several researchers within the University of Kentucky's Sanders-Brown Center on Aging has investigated the genetic risk of neuropathological traits commonly seen by neuropathologists performing ...

How diabetes risk genes make cells less resilient to stress

The cells in your pancreas, like people, can only handle so much stress before they start to break down. Certain stressors, such as inflammation and high blood sugar, contribute to the development of type 2 diabetes by overwhelming ...

Cell line models identify cause of melanoma with drug resistance

Melanoma is a type of cancer that originates from melanocytes, the cells responsible for producing skin pigment, and is known as the most lethal form of skin cancer due to its high rates of metastasis and recurrence. With ...

Cancer mutations caused by bacterial toxin preventable

Reports show that cancer is the second leading cause of death globally. Scientists from Duke-NUS Medical School have found DNA mutations in some cancers that link them to a bacterial toxin called colibactin. Their findings, ...

Genetics

Breaks in the genome

Breaks and rearrangements in the genome can lead to severe diseases, even if all genes remain intact. Hi-C, a method to map the three-dimensional structure of chromosomes, promises more reliable and accurate diagnoses of ...

Genetics

Neandertals may have had a lower threshold for pain

As several Neandertal genomes of high quality are now available researchers can identify genetic changes that were present in many or all Neandertals, investigate their physiological effects and look into their consequences ...

Genetics

Gene in fat plays key role in insulin resistance

Deleting a key gene in mice in just their fat made tissues throughout these animals insulin resistant, in addition to other effects, a new study by UT Southwestern researchers shows. The findings, reported in a recent issue ...

Gene-controlling mechanisms play key role in cancer progression

As cancer cells evolve, many of their genes become overactive while others are turned down. These genetic changes can help tumors grow out of control and become more aggressive, adapt to changing conditions, and eventually ...

Mutation mechanism discovered for neuroendocrine pancreatic cancer

Although neuroendocrine tumors of the pancreas are rare, the available treatment options are currently limited. Researchers have now managed to identify the mutation mechanism, namely a mutation on the gene that activates ...

Genetics

New mutations accumulate in reproductive cells of older mice

Older mice have more new mutations—changes in DNA sequence that occur in the individual rather than being inherited from a parent—than younger mice in the genomes of their mitochondria, according to researchers at Penn ...

Genetics

How to map brain connections using DNA barcodes

A new method developed at Cold Spring Harbor Laboratory (CSHL) uses DNA sequencing to efficiently map long-range connections between different regions of the brain. The approach dramatically reduces the cost of mapping brain-wide ...

Genetics

Researchers generate complete human X chromosome sequence

Researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), have produced the first end-to-end DNA sequence of a human chromosome. The results, published today in ...

Genetics

Artificial RNA editing with ADAR for gene therapy

Many of the diseases caused by point mutations have no established therapeutic approaches. Prof. Tsukahara and colleagues (Japan Advanced Institute of Science and Technology) are studying a therapeutic method using artificial ...

Genetics

Surprisingly many peculiar long introns found in brain genes

In a recent study of genes involved in brain functioning, their previously unknown features have been uncovered by bioinformaticians from the Moscow Institute of Physics and Technology and the Institute of Mathematical Problems ...

Genetics

New clues to lung-scarring disease may aid treatment

Scientists at Vanderbilt University Medical Center (VUMC) and the Translational Genomics Research Institute (TGen) in Phoenix, Arizona, have discovered previously unreported genetic and cellular changes that occur in the ...
