Human cells can convert RNA sequences into DNA

Cells include machinery that replicates DNA into a new set, and this, in turn, develops into a newly formed cell.

Researchers discover what fuels the immune system’s “natural killers”

Natural killer (NK) cells, while having a name straight out of a Tarantino film, are allies of humans when it comes to combating cancer and infections.

More informed choices of contraceptives can prevent breast cancer

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.

Study identifies new epigenetic control pathways in multiple myeloma growth

An international group of researchers from Japan, the United States, and the UK studied the role of the histone demethylase KDM5A in multiple myeloma.

Supercoiling characteristic of DNA's structure controls gene expression, research shows

The two meters of -stretched- DNA contained in human cells are continuously twisting and untwisting to give access to genetic information: when a gene is expressed to generate a protein, the two strands of DNA are separated to give access to all the machinery necessary for this expression, resulting in an excessive accumulation of coiling that needs to be resolved later.

New integrative genetic screening technology offers insights into role of DNA accessibility in cancer

In a new resource for the scientific community, published today in Nature Biotechnology, researchers in the lab of Neville Sanjana, PhD, at the New York Genome Center (NYGC) and New York University (NYU) developed CRISPR-sciATAC, a novel integrative genetic screening platform that jointly captures CRISPR gene perturbations and single-cell chromatin accessibility genome-wide.

3D biomaterial helps implanted stem cells stick around to reverse arthritis

A 3D biomaterial scaffold design to slowly release stem cells has worked to ensure implanted stem cells stick around to relieve pain and reverse arthritis in mice knee joints.

Study reveals DNA supercoiling is involved in regulating gene expression

The (when stretched) two-meter-long DNA molecule in each human cell is continuously being unpacked and packed again to enable the expression of genetic information.

Strong cell-cell junctions preserve the quiescent properties of stem cells

The skin is known to be the largest organ in the human body, and its outermost layer, called the epidermis, is renewed every three weeks.

Study reveals molecular mechanisms involved in the maintenance of naïve embryonic stem cells

Researchers have explained mechanisms that play a role in maintaining the embryonic stem cells in the most optimized state for use in regenerative medicine.

Stem cell therapy could help restore debilitating muscle loss that happens with age

As the name implies, induced pluripotent stem cells can become any type of cell in our body, and scientists have evidence that when they prompt them to become muscle progenitor cells they can help restore the sometimes debilitating muscle loss that happens with age.

ADAR1 protein offers a potential therapeutic target for cancer

A research team has discovered a new role of ADAR1 and found that the ADAR1p110 isoform controls genome stability at the ends of chromosomes.

Study reveals mechanism through which plant hormone controls cell division

The mechanism through which cytokinin—a plant hormone—regulates the division of cells has been identified.

Enzyme in fruit fly larvae plays key role in waking up brain stem cells

Researchers studying an enzyme in fruit fly larvae have found that it plays an important role in waking up brain stem cells from their dormant 'quiescent' state, enabling them to proliferate and generate new neurons.

Researchers explore the regulatory role of protein in human health and disease

Researchers from the University of Virginia, Lehigh University and the Massachusetts Institute of Technology are pooling their respective labs' expertise to unlock the mysteries of a protein that plays a critical regulatory role in human health and disease.

3D genome study reveals molecular regulatory mechanisms of human brain evolution

A team led by Prof. SU Bing from the Kunming Institute of Zoology (KIZ) of the Chinese Academy of Sciences (CAS), Prof. LI Cheng from Peking University, and Prof. ZHANG Shihua from the Academy of Mathematics and Systems Science of CAS has reported the highest resolution by far of the 3D genome of the primate brain, and demonstrated the molecular regulatory mechanisms of human brain evolution through cross-species multi-omics analysis and experimental validation. The study was published in Cell.
