Hui Zhang (Chemistry and Biochemistry) and a team of UNLV biochemistry researchers recently published a paper in the journal Nature Communications. The paper is entitled “Methylated DNMT1 and E2F are Targeted for Proteolysis by L3MBTL3 and CRL4DCAF5 Ubiquitin Ligase”. Lysine-specific methylation of histones is a major epigenetic modification that regulates chromatin structure and gene expression. Emerging evidence indicates that a large number of nonhistone proteins are also lysine methylated and a major function of this modification is to control the stability of the methylated proteins. The research team  discovered for the first time a novel mechanism by which the stability of methylated proteins is regulated to control the epigenetic inheritance of DNA methylation and gene expression during cell division.

Jun Yong Kang and Hai Huang (both Chemistry and Biochemistry), as well as computational study collaborators at the University of Colorado, Denver, published a research article, "Direct Aryloxylation/Alkyloxylation of Dialkyl Phosphonates for the Synthesis of Mixed Phosphonates," in Angewandte Chemie. This research demonstrates a new synthetic transformation of dialkylphosphonates to mixed phosphonates under mild reaction conditions. The mixed phosphonates are prevalent in pharmaceuticals and bioactive small molecules such as antibacterial, ligand prodrug, and enzyme inhibitors. This synthetic method avoids the use of toxic metals, hazardous chloride reagents, and moisture sensitive chloride intermediates for the synthesis of biologically important mixed phosphonate compounds.

Hong Sun (Chemistry and Biochemistry) and her laboratory's research were featured in the most recent issue of Research Features for their model on target acid sphingomyelinase (ASM) for anti-cancer therapy. Titled, "Acid Sphingomyelinase – A Novel Target for Anti-Cancer and Degenerative Diseases?," their research explores how ASM interacts with key components of the plasma membrane of the cell, thereby influencing cell signaling. Her team has discovered that mutations or abnormal expression in the gene that encodes ASM can result in a wide range of impacts, from regulating lifespan to enhancing the risk of cancer and neuron degenerative disease. According to the magazine, "As we enter the new year we look forward to showcasing new research from around the world and learning how researchers are working to make a difference. This issue we pay homage to the scientists behind our ever-increasing quality of life as we feature the latest in health research. Whether it's the technology that allows us to peer deep into the body or medicines that extend the lives of those with chronic diseases, it's easy to see how advances in health and medicine have touched the lives of nearly every person on the planet." Other laboratories featured included those at Stanford University, University of Chicago, and Brown University.

Ken Czerwinski (Chemistry and Biochemistry) has accepted an invitation from the director of the Nuclear and Radiation Studies Board at the National Academies of Sciences, Engineering, and Medicine to serve as an expert on a study mandated by Congress on the treatment of low-level radioactive waste at the Hanford site in Washington state. Czerwinski, a radiochemist, will serve on this task force for the next 20 months.

David Hatchett (Chemistry and Biochemistry) was recently awarded a $232,936 research grant from National Security Technologies. The funding will support his “Metals Separation Project.”

MaryKay Orgill (Chemistry and Biochemistry) was shocked by the news of the Oct. 1 incident on the Las Vegas Strip. How she reacted and some of her students' responses were featured recently in Chemical & Engineering News.   The morning after the incident, Orgill decided to talk to her class about how the mass shooting affected them. She brought up Martin Luther King Jr.'s quote, "“Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.” The article includes excerpts from just two of the more than 80 responses she received that exemplify what those students took from her lesson.

Jun Kang (Chemistry and Biochemistry) and the Division of Research and Economic Development have partnered with the reagent company Kerafast to market and distribute two novel reagents. The agreement allows Kerafast, a global supplier of biological research tools, to market two reagents that generate phosphorus- and nitrogen-containing compounds without toxic heavy metals. The reagents should make new drug development less costly and more environmentally friendly. These compounds are particularly important in pharmaceuticals. These reagents are the first products to be commercially available due to support from the 2015 Faculty Opportunity Awards.

Laurel Raftery, Andrew Andres, Ai-Sun "Kelly" Tseng, and Boo Shan Tseng (all Life Sciences), and Hong Sun (Chemistry & Biochemistry), have been awarded a National Science Foundation Major Research Instrumentation grant to purchase a multiphoton fluorescence imaging system titled "MRI: Acquisition of a High Speed Multiphoton Laser-Scanning Microscope for Research and Training at UNLV." Raftery is the principal investigator, while Andres, Sun, Tseng, and Tseng are co-principal investigators. Collaborators on the award are Nora Caberoy, Sophie Choe, Jeffery Shen, and Jenifer Utz (all Life Sciences), Rochelle Hines (Psychology), and Kwang Kim (Mechanical Engineering). The $998,614 microscope system will be installed in 2018, and operated on a first-come-first-served,  fee-for-service basis, through the UNLV confocal and biological imaging core. It will be Nevada's first multiphoton system for thick tissue (1mm) time-lapse imaging. This technology enables new discoveries in neurobiology, tissue formation, organ repair and whole-scale regeneration, and ion flux in biological tissues and in eletroactive polymer materials for engineering, and expands to other research areas through graduate student training and through recruitment of new faculty and other scientists to work at UNLV and other Southern Nevada technology centers.  

Aug 17, 2017
Jason Richards (Chemistry and Biochemistry), a doctoral student in the radiochemistry program, was awarded a first-place prize in the 2017 Innovations in Nuclear Technology R&D Awards sponsored by the U.S. Department of Energy's office of nuclear technology R&D. His award is in the open competition in the category of nuclear science and engineering. His award-winning research paper, “Selective Partitioning of Ruthenium from Nitric Acid Media,” was published in the journal Solvent Extraction and Ion Exchange in February.

James Croft and Balakrishnan Naduvalath (Chemistry and Biochemistry) and a team of researchers recently published a paper, "Universality and Chaoticity in Ultracold K + KRb Chemical Reactions," in the journal Nature Communications. The team performed the first-ever quantum-mechanical simulation of the benchmark ultracold chemical reaction between potassium-rubidium (KRb) and a potassium atom, opening the door to new controlled chemistry experiments and quantum control of chemical reactions that could spark advances in quantum computing and sensing technologies. The research by the multi-institutional team simulated the ultracold chemical reaction, with results that had not been revealed in experiments. The research addressed open questions about whether chemical reactions occur at a billionth of a degree above absolute zero and whether the outcome can be controlled. Scientists worldwide are addressing these questions experimentally by cooling and trapping atoms and molecules at temperatures close to absolute zero and allowing them to interact chemically. This field of chemistry, widely referred to as ultracold chemistry, has become a hotbed for controlled chemistry experiments and quantum control of chemical reactions, the holy grail of chemistry.
