A team from Universitat Jaume I creates a biostimulant composition using proline particles encapsulated in silica, enhancing plant tolerance to drought, high temperatures and salinity. The new compound's production process is scalable, cost-effective and reproducible, with potential for industrial-level application.
Researchers at King's College London have developed a novel drug delivery system using biologically compatible peptides found in chicken feathers and skin tissue. This innovative approach enables targeted delivery of chemotherapy drugs and repair of faulty enzymes, potentially reducing side effects and improving treatment outcomes.
Candida albicans requires proline metabolism to mount virulent infections, according to a new study. Proline is an important source of energy for the fungus, and its breakdown in the mitochondria generates chemical energy similar to glucose.
Researchers found that a mutation in RPL3L, expressed only in heart and skeletal muscle, leads to impaired cardiac contractility by causing ribosomal collisions and protein folding abnormalities. The study aims to develop new treatments for cardiomyopathy and atrial fibrillation.
Researchers have developed a novel catalytic approach to synthesize monocyclic 3-(pyrrol-1-yl)-azetidin-2-ones, which show potential as therapeutic agents. The method yields all four diastereomers with high selectivity and has been published in Current Organocatalysis.
Scientists used multi-isotope imaging mass spectrometry to identify key contributors to blood vessel obstruction in PAH. The study reveals proline and glucose play a crucial role in forming excess scar tissue, which obstructs blood flow.
Researchers found that elevated plasma levels of proline and a diet rich in this amino acid are associated with severe depression. The study also discovered a link between microbiota alterations and proline metabolism impacting depressive mood.
Researchers developed a new NMR spectroscopic method to map IDP function more easily, fast, and accurately. The method sheds light on mechanisms of diseases like Parkinson's, Alzheimer's, and type 2 diabetes.
Researchers discovered spider silk's supercontraction property, where it twists and contracts in response to humidity changes, potentially leading to new robotic actuators. This unique property could enable precise control of motions using controlled humidity levels.
Researchers have introduced polyproline as an effective cryoprotectant for monolayers of cells, doubling cell recovery after freezing compared to dimethyl sulfoxide. The proline/polyproline combination minimizes solvent exposure and retains cell functions.
Researchers found that diabetic rats on a high protein diet with arginine and proline showed better wound healing compared to those without supplementation. The study suggests that arginine and proline enrichment could offer new hope for effective treatment in diabetic patients with chronic wounds.
Harvard researchers uncover how halofuginone, a compound derived from an ancient Chinese herb, regulates autoimmunity and inflammation by triggering a stress-response pathway. The discovery provides new insights into the physiological regulation of the immune system and novel therapeutic approaches for autoimmune disorders.
Researchers found that a common variant of the p53 gene increases inflammatory responses following DNA damage, making African Americans more susceptible to certain diseases and cancers. The proline variant interacts with NF-kB, a protein complex regulating the immune response, leading to enhanced activation of inflammation genes.
Research team designed synthetic molecules to study proline residue's role in cancer cell apoptosis by XIAP protein. The results suggest that these tetrapeptide analogs can be further developed into new molecular tools to analyze protein-protein interactions and signal transduction pathways of XIAP in cancer cells.
Scientists have visualized a donut-shaped structure of an enzyme involved in degrading proline, a key amino acid in metabolism. This discovery will aid in understanding the enzyme's function and developing drugs to inhibit its activity.
Researchers discovered that longer proline repeats contract protein bubbles, helping to form longer enamel crystals. This finding could lead to new ways to engineer tooth enamel.
The study reveals that Fbox proteins alternate between attaching to and being kicked off CRL1 by competing protein CAND1. This process is stabilized by the phosphorylated substrate N8, allowing for efficient degradation of aberrant proteins. The research highlights the importance of the proline residue in Fbox protein-CRL1 interaction.
Spider silk exhibits different mechanical properties based on its amino acid composition, with proline-rich silks behaving like rubber bands and low-proline silks acting as rigid springs. The presence of proline affects the silk's hydration level, causing some silks to shrink and swell more than others.
Scientists created a model of proline dehydrogenase, an enzyme that enables the creation of superoxide, a reactive oxygen species involved in cell death and cancer prevention. The human form of this enzyme is difficult to work with, so researchers studied its bacterial counterpart, Thermus thermophilus.
