Study: Cancer stem-like cells are maintained by MTHFD2 mitochondrial metabolic enzyme

An increase in the incidence and mortality rate of cancer has been noted worldwide, especially for lung cancer.

Researchers comprehensively sequence the human immune system

For the first time ever, researchers are comprehensively sequencing the human immune system, which is billions of times larger than the human genome. In a new study published in Nature from the Human Vaccines Project, scientists have sequenced a key part of this vast and mysterious system -- the genes encoding the circulating B cell receptor repertoire.

Cloning-free Nested CRISPR uses long DNA fragments for efficient gene editing

CRISPR is a technique that is revolutionizing biomedical research through high-precision genome editing. However, even though it allows the creation or correction of mutations consisting of a single or few nucleotides with relative ease, it still possesses limitations upon introducing larger fragments of DNA in the genome.

New discovery can explain resistance of cancer types to fatty acid metabolism inhibition

Fatty acid metabolism is an essential process in tumor growth and proliferation. Despite different attempts to block fatty acid metabolism as a therapeutic strategy to reduce tumor size and growth, the outcome was not always positive.

Researchers describe first case of patient affected by dysfunctions in SLC28 gene family

A research team has described the first case of a patient affected by dysfunctions in a nucleoside transporter of the SLC28 gene family, which brings a set of genes which were not related to human pathologies in the scientific bibliography so far.

Mapping mutations in esophageal cancer could improve treatment options

Mutations that cause oesophageal adenocarcinoma have been mapped in unprecedented detail - unveiling that more than half could be targeted by drugs currently in trials for other cancer types.

UCLA-led scientists discover new clues to what goes wrong in the brains of people with autism

A team of UCLA-led scientists has discovered important clues to what goes wrong in the brains of people with autism -- a developmental disorder with no cure and for which scientists have no deep understanding of what causes it.

Researchers identify major compounds that impart taste to pufferfish without harmful toxin

Some people consider pufferfish, also known as fugu, a delicacy because of its unique and exquisite flavor, which is perhaps seasoned by knowledge that consumption of the fish could be deadly.

CRISPR-Cas9 circular permutants can sense and respond to viral proteases

Using a technique called circular permutation, researchers at the University of California Berkeley have created a new suite of Cas9 variants called Cas9-CPs, which will simplify design of Cas9-fusion proteins for diverse applications beyond simple DNA cutting, such as base editing and epigenetic modifications.

New method to speed up genetic diagnosis of Huntington’s disease

Elongated segments of DNA cause Huntington's disease and certain other disorders of the brain. Researchers funded by the SNSF have developed a method to determine the length of the mutated genes quickly and easily.

PAC1R mutation in children with autism may be linked to severity of social problems

A mutation of the gene PAC1R may be linked to the severity of social deficits experienced by kids with autism spectrum disorder, finds a study from a multi-institutional research team led by Children's faculty.

Study elucidates how essential amino acid in humans acts as growth signal for cells

A recent study from the Laxman lab elucidates how a small metabolite and amino acid, methionine, acts as a growth signal for cells, by setting into motion a metabolic program for cell proliferation.

New method for automation of DNA origami

Nature has made extravagant use of a simple molecule--DNA, the floorplan of all earthly life.

Research illuminates abilities of ADAR1 to ‘hyper-mutate’ tumor suppressor RNAs in leukemia

Writing in the January 3 issue of Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of "copy editing" by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and represent a new therapeutic target for preventing cancer cell resistance to chemotherapy and radiation.

New technique using microneedles may mean rapid diagnoses of major illnesses

When people are in the early stages of an undiagnosed disease, immediate tests that lead to treatment are the best first steps. But a blood draw -- usually performed by a medical professional armed with an uncomfortably large needle -- might not be quickest, least painful or most effective method, according to new research.

Weakened metabolism of immune T cells may account for serious complications in elderly

The elderly suffer more serious complications from infections and benefit less from vaccination than the general population.

New discovery will improve the safety and predictability of CRISPR

Scientists have discovered a simple set of rules that can be used to precisely predict how DNA will be modified by the CRISPR gene editing technique.

Epigenetic maps of the inner ear could lead to development of therapeutics for hearing loss

Epigenetics is the expression and control of genes. The epigenetics involved in the inner ear is a critical part of the mystery of hearing.

Research may pave way for development of potent weapons against cancer

Despite significant advances in cancer research, the disease continues to exact a devastating toll. Because cancer is a disease of the body's own cells, which mutate and develop under evolutionary pressure, conventional treatments like chemotherapy and radiation often leave behind a residue of resistant cells that go on to expand and wreak havoc.

New method enhances efficiency and accuracy of single cell RNA sequencing

In the era of personalized medicine, scientists are using new genetic and genomic insights to help them determine the best treatment for a given patient. In the case of cancer, the first step toward these treatments is an investigation into how tumor cells behave in an effort to figure out the best drugs to use to attack them.
