| Most 'silent' genetic mutations are harmful, not neutral, a finding with broad implications Posted: 08 Jun 2022 08:25 AM PDT In the early 1960s scientists deciphered the genetic code of life, determining the rules by which information in DNA molecules is translated into proteins, the working parts of living cells. They identified three-letter units in DNA sequences, known as codons, that specify each of the 20 amino acids that make up proteins. Occasionally, single-letter misspellings in the genetic code, known as point mutations, occur. Point mutations that alter the resulting protein sequences are called nonsynonymous mutations, while those that do not alter protein sequences are called silent or synonymous mutations. Between one-quarter and one-third of point mutations in protein-coding DNA sequences are synonymous. Ever since the genetic code was cracked, those mutations have generally been assumed to be neutral, or nearly so. |
| Pregnant women produce super antibodies to protect newborns, now scientists know how Posted: 08 Jun 2022 08:24 AM PDT During pregnancy, a subtle molecular change allows immunoglobulin G -- the body's most common type of antibody -- to take on an expanded protective role. Now scientists say this natural process can be replicated to improve vaccines and other antibody-based treatments. |

| Lessons on how to sleep: What we can learn from worms Posted: 08 Jun 2022 08:24 AM PDT Caenorhabditis elegans is a worm that has been used for decades as a model organism. Researchers have found that a specific neuron, called ALA, and the amount of calcium it contains are essential for the homeostatic regulation of sleep in C. elegans. ALA was found to contain more calcium ions when the worms were awake for a long time, and less when they slept. Considering that the molecules involved in sleep regulation are widely conserved, these results may translate to other animals, including humans. |

| Nanotechnology used to destroy and prevent relapse of solid tumor cancers Posted: 07 Jun 2022 09:10 AM PDT As people across the globe look forward to longer life expectancies, malignant cancers continue to pose threats to human health. The exploration and development of immunotherapy aims to seek new breakthroughs for the treatment of solid tumors. Although immune checkpoint-based immunotherapy has been shown to have great potential, only a small proportion of patients fully respond to this therapy, and the relevant molecular mechanisms need to be further explored. This delivery method is however complex and inefficient. In a breakthrough development, a team of scientists has formulated a novel vaccine which showed high efficacy in the treatment of solid tumors, achieving complete clearance of solid tumors and inducing long-lasting immune memory. This prevents the relapse of tumor growth that the patient originally presented with and provides immunity against similar tumour types. This was shown through the application of this vaccine on melanoma tumor models. |
| New model offers physics-inspired rankings evaluation Posted: 07 Jun 2022 09:10 AM PDT Researchers describe a new way to evaluate rankings. Their goal is not to find one true hierarchy, but to calculate the spread of all possible hierarchies, with each one weighted by its probability. |
| Targeted micronutrition ameliorates allergy symptoms Posted: 07 Jun 2022 09:10 AM PDT Micronutrient deficiencies can promote inflammation and render the immune system particularly sensitive to allergenic substances. In particular, iron deficiency signals danger to immune cells and leads to a more pronounced, exaggerated immune response. For the first time, scientists have conducted a placebo-controlled trial and showed that targeted dietary measures can reduce the symptom burden in allergic reactions. The researchers are therefore treading a completely new path in the care of allergy sufferers. |

| Neuroscientists identify role of basolateral amygdala neurons Posted: 07 Jun 2022 09:08 AM PDT The basolateral amygdala (BLA) is a region of the brain that has been almost exclusively studied in the context of fear and emotion. Only recently have researchers begun to question whether the BLA may play a larger, overarching role in memory and behavior. Yet almost nothing is known about the neuronal activity of the BLA during naturalistic behavior. To address these questions, neuroscientists at the Sainsbury Wellcome Centre at UCL observed the neuronal activity in this brain region while rats freely engaged with a variety of different ethological stimuli. Interactions with ethological stimuli are relevant to the animal's survival and to the propagation of its genes, and include food, prey and conspecifics. In a new study, published today in Cell Reports, the researchers demonstrate strong responses to these classes of events in the BLA. |
