Finding Leukemia’s Weakness Using Genome-Wide CRISPR Technology

A team of researchers at University of California San Diego School of Medicine and Moores Cancer Center used CRISPR technology to identify key regulators of aggressive chronic myeloid leukemia, a type of cancer that remains difficult to treat and is marked by frequent relapse. “We used CRISPR technology to carry […]

A subset of suppressive lymphocytes switches to promote autoimmune disease when activated by glycolipids in the face of inflammation

Researchers from Karolinska Institutet in collaboration with a lab in San Antonio USA, have uncovered how a specific population of lymphocytes promotes autoimmune disease by giving up their regulatory role in the immune system. The newly discovered mechanism is published in PNAS from research led by Dr. Saikiran Sedimbi and […]

Electronic health records used in study of drug-effectiveness to reduce risk of Alzheimer’s disease

Researchers have harnessed the power of electronic health records to gain insight in the potential of inflammation-controlling medications to reduce a patient’s Alzheimer’s disease risk. Rong Xu, professor of Biomedical Informatics and director of the Center for Artificial Intelligence in Drug Discovery at Case Western Reserve University; Mark Gurney, chairman […]

The optimal immune repertoire for bacteria

Before CRISPR became a household name as a tool for gene editing, researchers had been studying this unique family of DNA sequences and its role in the bacterial immune response to viruses. The region of the bacterial genome known as the CRISPR cassette contains pieces of viral genomes, a genomic […]

A Phenoptosis Perspective on the Evolution of Exceptional Human Longevity

The conclusion to today's open access paper opens with the following declaration: “There is still no agreement among gerontologists as to the main aging-related issue: whether it is an accidental accumulation of damage in the organism or a result of the operation of a specially evolved program.” This is true in the […]

Using the CellAge Database to Find Genes Associated with Inhibition of Cellular Senescence

The CellAge database was announced last year, a repository of information on genes linked to cellular senescence. Cells become senescent in response to a variety of stresses, or upon reaching the Hayflick limit. A senescent cell ceases replication and secretes inflammatory and pro-growth signals. The process serves a useful function when such cells are present for […]

DNA Damage During Cell Replication is Probably Not Important in Mammalian Aging

The size of the contribution of stochastic nuclear DNA damage to aging is debated. It causes cancer, when rare combinations of cancerous mutations occur and suppression of those early cancerous cells fails, but can it give rise to a meaningful degree of tissue dysfunction otherwise? The present consensus is that most such […]

When Damaged, the Adult Brain Repairs Itself by Going Back to the Beginning

When adult brain cells are injured, they revert to an embryonic state, according to new findings published in the journal Nature by researchers at University of California San Diego School of Medicine, with colleagues elsewhere. The scientists report that in their newly adopted immature state, the cells become capable of re-growing […]

Researchers restore sight in mice by turning skin cells into light-sensing eye cells

Researchers have discovered a technique for directly reprogramming skin cells into light-sensing rod photoreceptors used for vision. The lab-made rods enabled blind mice to detect light after the cells were transplanted into the animals’ eyes. The work, funded by the National Eye Institute (NEI), published in Nature. The NEI is […]

Landmark study of adolescent brain development renews for additional seven years

With nearly $290M of new funding for seven years to research institutions around the country, the National Institutes of Health renewed its commitment to the Adolescent Brain Cognitive Development (ABCD) Study(link is external), the largest long-term study of brain development and child health ever conducted in the United States. Launched in […]
