Unveiling Epidermal Hemoglobin: A Breakthrough in Skin Research

Scientists have, for the first time, demonstrated the presence of hemoglobin—a protein primarily known for its role in binding with oxygen within red blood cells—in the epidermis, the outermost tissue layer of human skin.

New Proof-of-Concept Model for Delivering Gene Editing Tools to Treat Blood Disorders

In a step forward in the development of genetic medicines, researchers at Children's Hospital of Philadelphia (CHOP) and the Perelman School of Medicine at the University of Pennsylvania have developed a proof-of-concept model for delivering gene editing tools to treat blood disorders, allowing for the modification of diseased blood cells directly within the body.

Scientists Develop Method to Create Artificial Allosteric Sites in Protein Complexes

According to a recently published research paper by a team of scientists, a groundbreaking approach has been developed to create artificial allosteric sites (where by binding an effector molecule, activity at the distal active site is regulated) in protein complexes.

Computational Approach Could Uncover Transcriptional Regulatory Mechanisms and Causal Noncoding Variants

Less than two percent of the human genome codes for proteins, with the rest being noncoding and likely helping with gene regulation.

STING-seq Discovers Causal Variants and Genetic Mechanisms for Blood Cell Traits

A major challenge in human genetics is understanding which parts of the genome drive specific traits or contribute to disease risk. This challenge is even greater for genetic variants found in the 98% of the genome that does not encode proteins.

Sickle Cell Disease Cure? Prime Editing Offers Hope for Blood Disorder

At St Jude Children’s Research Hospital and the Broad Institute of MIT and Harvard, researchers have shown how prime editing could help correct the mutation that results in sickle cell disease in a possibly curative method.

Researchers provide an entirely new perspective on tissue oxygenation

Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others.

Globins in the body help fight liver disease

Anti-fibrotic therapy is still a medical necessity in the treatment of chronic liver disease in humans. The anti-fibrotic activity of globin family members in hepatic stellate cells (HSCs), the principal cell type involved in liver fibrosis, was reported by a research group led by Professor Norifumi Kawada of Osaka Metropolitan University (OMU).

Researchers discover dysregulation of transfer RNA expression in cancer

A recently published paper in the journal Molecular Cancer by the group of Dr. Manel Esteller, Director of the Josep Carreras Leukaemia Research Institute, ICREA Research Professor and Genetics Chairman at the University of Barcelona, shows that transfer RNAs for certain amino acids are altered at the epigenetic level in some types of cancer, expressing it in an exaggerated manner in some cases and being deficient in others.

Hemoglobin plays role as a chemosensory signal for mother mice to protect offspring

Biochemists in Japan were surprised to discover that the molecule hemoglobin in the blood works not only as an oxygen carrier, but when the blood is spilled as a result of aggression, accident or predator attack, the molecule also acts as a chemosensory signal -; a chemical stimulus picked up by the senses, namely smell in this case -; for lactating mother mice, prompting digging or rearing behavior in them to check the surrounding environment and keep their offspring safe.

New technology offers an alternative way to produce highly detailed images of the brain

The gold standard in functional brain imaging for over two decades, functional magnetic resonance imaging (fMRI) has transformed the landscape of research and clinical care. Yet, because of its cost and functional limitations, scientists have continued to look for new ways to see into the human brain.
