RNA Editing Defects in the Autistic Brain

A molecular mechanism that explains the development of autism remains enigmatic. Here, researchers from UCLA sequenced the DNA and RNA from patients with and without autism to catalog differences in RNA editing – a little-studied process where the RNA produced from our genes is edited to produce novel RNAs that differ from the DNA sequence [...]

New Nucleotides = New Genes = New Proteins

DNA is not new. A pairs with T, G pairs with C, and these 4 nucleotides are organized into genes and intervening sequences that twist up into the famous double helix that ultimately explains all of life and heredity. But what if this settled science was reimagined as something new? https://www.economist.com/science-and-technology/2019/01/19/adding-new-dna-letters-make-novel-proteins-possible

Rearranged DNA in Alzheimer’s Disease Susceptibility Genes?

A very strange but crucial phenomenon occurs in the DNA of B and T cells that comprise the adaptive immune system: their DNA is cut and pasted in different, random combinations during a very complex process that ultimately helps to fights infection. Nowhere else in the body at any stage of development has this been [...]

Why doesn’t the maternal immune system attack a developing fetus?

The immune system differentiates between “self” and “non-self”, and attacks any entity it perceives as foreign. Microorganisms like bacteria and viruses are obviously recognized as foreign, but the immune system also recognizes tissue from different individuals within the same species as foreign, which can cause major problems for organ transplantation. But why doesn’t the maternal [...]

How do cancer cells move around the body?

Metastasis – the process by which cancer cells leave their tumor-of-origin, enter the blood stream and colonize distant tissues – is responsible for 90% of cancer deaths. The first step in this complex process is invasion into surrounding tissue and blood vessels, which requires the degradation of connective tissue (extracellular matrix) that compartmentalizes these sub-regions. [...]

2018 Nobel Prize in Physiology/Medicine Awarded for Cancer Immunotherapy

Congratulations to James Allison and Tasuko Honjo for winning the 2018 Nobel Prize for Physiology/Medicine. Specifically, they discovered the CTLA-4 and PD-1 proteins, and found that inhibiting these proteins allowed the immune system to attack tumors. These discoveries were instrumental in launching the cancer immunotherapy revolution. 2018 Nobel Prize

How does Zika virus cause birth defects?

How does Zika virus cause birth defects?  This study demonstrates that the birth defects associated with Zika virus infection arise due to the detrimental effects of type 1 interferon, which (paradoxically) is produced by your immune system to protect you from viral infections.  This is a story that is interesting in its own right, but [...]

FDA-Approved Sedative Rapidly Reduces Suicidal Thoughts

Ketamine is used clinically as a sedative, but also abused recreationally due to its hallucinogenic properties. Here, researchers describe the amazing ability of ketamine to rapidly reduce suicidal thoughts. What is the molecular mechanism? And how can we use that information to prevent these thoughts from appearing in the first place? Ketamine Reduces Suicidal Thoughts
