How Enzymes Handle the Energy Derived from the Cleavage of High-energy Phosphate Compounds [Enzymology]

Introduction I was accepted at the Federal University of Rio de Janeiro Medical School when I was seventeen years old. At that time, I was absolutely sure I was going to be a surgeon. One year later, I received an offer for a fellowship to work in a research laboratory. This originally had not been part of my future professional plan, but I was desperately in need of a source of income, so I joined the research laboratory at the age of eighteen. During the medical school course in Rio de Janeiro, I lived the hormonal tempest typical of youth, and my certainties were shaken badly. I soon discovered that I did not have much of a future in either surgery or clinical practice, but my interest in science increased. I received my M.D. degree in 1961, when I was twenty-three years old, and it was time to decide what to do with my life. With a significant degree of uncertainty, I opted for research. Fortunately, I had excellent supervisors who smoothed out my rite of passage into science. As a medical student in Rio de Janeiro, I worked with Walter Oswaldo Cruz (Fig. 1) in his research laboratory, and shortly after receiving my M.D. degree, I went to the National Institutes of Health (NIH) in Bethesda, where I had the good fortune to work with Herbert and Celia Tabor (Fig. 2) for eighteen months. When I returned to Rio de Janeiro, I was sure that my vocation was...

Smurf1 Protein Negatively Regulates Interferon-{gamma} Signaling through Promoting STAT1 Protein Ubiquitination and Degradation [Signal Transduction]

Interferons are important cytokines that mediate antiviral, antiproliferative, antitumor, and immunoregulatory activities. However, uncontrolled IFN signaling may lead to autoimmune diseases. Here we identified Smurf1 as a negative regulator for IFN-γ signaling by targeting STAT1 for ubiquitination and proteasomal degradation. Smurf1 interacted with STAT1 through the WW domains of Smurf1 and the PY motif in STAT1 and catalyzed K48-linked polyubiquitination of STAT1. Interestingly, the Smurf1-mediated ubiquitination and degradation did not require STAT1 tyrosine and serine phosphorylation. Subsequently, overexpression of Smurf1 attenuated IFN-γ-mediated STAT1 activation and antiviral immune responses, whereas knockdown of Smurf1 enhanced IFN-γ-mediated STAT1 activation, expression of STAT1 target genes, and antiviral immune responses. Furthermore, IFN-γ stimulation led to enhanced expression of Smurf1. Therefore, our results demonstrate that Smurf1 is a negative feedback regulator for IFN-γ signaling by targeting STAT1 for ubiquitination and proteasomal degradation.

Reduce Pain By Looking Away

When you are getting an injection, do you look at the needle or look away? Research suggests that looking away when receiving an injection reduces the strength of the expected pain. In the study, it was discovered that when participants viewed a video of a needle pricking a hand, they experienced a pain that was more intense than viewing a hand only or a hand that was being touched by a Q-tip. The intense pain sensation was also accompanied by increased activity of the participants' autonomic nervous system.

Watch When You Eat

Be careful when you eat. A study published in the journal Cell Metabolism indicates that eating at random times throughout the day can lead to weight gain. The researchers believe this to be so because our organs, including those of the digestive system, have times when they work most efficiently and times when they rest. Our metabolic cycles are set to "turn on" when we eat and slow down when we are not eating. Eating at various times of the day can upset these metabolic cycles.
