KAUST researchers have identified a protein complex of HuR and YB1 that stabilizes messenger RNA during muscle-fiber formation. The complex protects RNA as it carries muscle-forming code through the cell. Further research aims to elucidate the individual roles of each protein in the stabilization process. Why it matters: Understanding this RNA-stabilizing complex could lead to new therapies for muscle recovery and the prevention of muscle-related pathologies.
KAUST Discovery Associate Professor Stefan Arold has established KAUST's first structural biology lab specializing in determining the atomic 3D structure of proteins and other biological macromolecules. The lab setup involved challenges such as assembling instruments and continuing research, but the Bioscience Core Lab at KAUST and support from colleagues aided in the process. Arold's research focuses on understanding protein function through an integrated 'hybrid' approach to analyze 3D structure and function of proteins. Why it matters: This new lab enhances KAUST's capabilities in molecular biophysics and structural biology, enabling advanced research into the functions of proteins and their implications for health and disease.
KAUST researchers developed a statistical approach to improve the identification of cancer-related protein mutations by reducing false positives. The method uses Bayesian statistics to analyze protein domain data from tumor samples, accounting for potential errors due to limited data. The team tested their method on prostate cancer data, successfully identifying a known cancer-linked mutation in the DNA binding protein cd00083. Why it matters: This enhances the reliability of cancer research at the molecular level, potentially accelerating the discovery of new therapeutic targets.
A KAUST team discovered a simple method to fabricate microspheres using block copolymer self-assembly. The resulting particles have pH-responsive gates and a highly porous structure, granting them ultrahigh protein sorption capacity. The team leveraged their expertise in block copolymers and self-assembly to achieve this. Why it matters: This new method and the resulting particles have potential applications in biotechnology, medicine, and catalysis, advancing materials science in the region.
KAUST Research Scientist Dr. Ram Karan received a Young Scientist Award at the 15th International Congress on Thermophiles in Japan for his work on extremozymes from Red Sea brine pools. His research focuses on identifying, purifying, and bioengineering microbial proteins from these pools. He utilizes single-amplified genomes (SAGs) to produce extremozyme proteins without needing to grow cells in the lab. Why it matters: This award recognizes KAUST's innovative research into extremophiles, which have the potential to develop novel, sustainable biotechnical processes for industrial applications.
KAUST researchers have determined the atomic 3D structure of a key protein involved in plant stress signaling using X-ray crystallography at the SOLEIL synchrotron in France. Postdoctoral fellow Umar Farook Shahul Hameed optimized a tiny crystal of the plant enzyme for over six months. The team used the EIGER 9M detector to capture the weak diffraction pattern from the crystal. Why it matters: Understanding the interactions between proteins that communicate plant stress could lead to engineering more stress-tolerant crops, enhancing food security.
Dr. John Bedbrook of DiCE Molecules LLC spoke at KAUST about the challenges of feeding a growing population with increasingly stressed arable land. He noted the increasing demand for meat in emerging economies exacerbates the problem. Bedbrook emphasized the role of genetics and hybridization in improving crop yields and quality to address food security. Why it matters: Investments in agricultural biotechnology are crucial for the GCC region to enhance food security and reduce reliance on imports amid changing climate conditions.
KAUST researchers are exploring the potential of algae for various high-value applications, including animal feed, crop fertilizers, and waste remediation. Claudio Grunewald directs a project focused on producing high-protein algae for agriculture. Kyle Lauersen brings expertise in algal synthetic biology and metabolic engineering. Why it matters: Investment in algae research and biotechnology could yield significant returns for Saudi Arabia, contributing to sustainable solutions and economic diversification.
