Environmental Toxicology Faculty Lead in Solving Important PFAS Contamination Problems

Per- and polyfluoroalkyl substances (PFAS), widely used in industrial and consumer products, have become a major environmental and public health concern.  They are known as forever chemicals because their fluorine carbon bonds are strong and extremely resistant to degradation.  Four ETOX faculty, Jinyong Liu, Haizhou Liu and Yujie Men, professors of Chemical and Environmental Engineering and Ying-Hsuan Lin, a professor of Environmental Sciences, are making significant progress in identifying chemical and microbiological processes that can degrade PFAS and clean up contaminated industrial sites and water.  The work of these faculty and their research teams have been highlighted in a recent article in the Fall 2023 edition of UCR Magazine.  Our congratulations to Jinyong, Haizhou, Yujie and Ying-Hsuan and their research groups for this recognition of their important work.

Prof. Mirhi Ozkan Investigates Carbon-Capturing Materials



A research team led by Dr. Mihri Ozkan, a Professor of Electrical and Computer Engineering and an ETOX faculty member, has recently conducted an exhaustive analysis of extremely thin MXene and MBene compounds, which because of their large surface area, have the potential to absorb significant amounts of carbon dioxide from the atmosphere.  If their research continues to be successful, these compounds will help reduce the harmful effects associated with climate change by safely capturing carbon dioxide. Their work has recently been published in the journal Chem and was the focus of a UCR News article. Our congratulations to Mihri and her collaborators for their innovative and impactful research.  [The figure above is from their Chem article.]

Research Shows High Intake of Soybean Oil Induces Colitis in Mice



Recent research by Prof. Frances Sladek, an ETOX faculty member, Prof. James Borneman, Research Scientist Poonam Deol (shown above in photo from UC Riverside News) and colleagues has shown that the consumption of elevated levels of soybean oil by mice alters the bacterial microflora in the gut and resulted in a high incidence of colitis - a form of inflammatory bowel disease, or IBD, characterized by chronic inflammation of the large intestine.  Their studies indicate that olive oil, which has lower amounts of linoleic acid, is a healthier oil to consume. Their work was published in the journal Gut Microbes.  A news release with more detail can be found at UC Riverside News.  

More recently, their work has also been featured on an ABC7 Eyewitness News segment in the Southern California area.  Our congratulations to Frances, Poonam and James for the recognition of their research.

Discovery Leading to Potential Degradation of Select PFAS Chemicals by Professors Men and Liu is Highlighted

Professors Yujie Men, Jinyong Liu, ETOX faculty members, graduate student Bosen Jin and colleagues have discovered two strains of bacteria which are capable of degrading chlorinated forms of per- and poly-fluoroalkyl substances (PFAS).  PFAS are so resistant to degradation that they are called forever chemicals.  The newly identified bacteria offer hope that a low cost approach can be found to degrade the PFAS class of chemicals. Their work has recently been published in the journal Nature Water.  Their work has resulted in a UCR News article and a brief mention in the Christian Science Monitor.  Our congratulations to Bosen, Yujie, Jinyong for the recognitions of their work.  [The above illustration is from the UCR News article.]

Professors Zhou and Chen Uncover Multigenerational Effects of Dicyclohexyl Phthalate


Changcheng Zhou and Qi Chen, professors in the Biomedical Sciences Division and Environmental Toxicology faculty members, and their colleagues have recently investigated the effects of paternal exposure to dicyclohexyl phthalate, or DCHP, on the metabolism of first generation (F1) and second generation (F2) offspring in mice.  As described in a UCR News article, "the researchers found that paternal DCHP exposure for four weeks led to high insulin resistance and impaired insulin signaling in F1 offspring. The same effect, but weaker, was seen in F2 offspring." Their research indicates that "paternal exposure to endocrine disrupting phthalates may have intergenerational and transgenerational adverse effects on the metabolic health of their offspring".  The research article has recently been published in Environment International. Our congratulations to Chengchang and Qi for this recognition of their important research.

Gonzalez and Wang Help Identify New Enzyme Involved with COVID-19 Infection

Dr. Gwendolyn Gonzalez, ETOX alumna and Yinsheng Wang, Distinguished Professor of Chemistry and ETOX faculty member, were part of a research team led by Tariq Rana of UC San Diego that identified a new enzyme called, as described in the UC San Diego Today article, "phosphorylated CTD-interacting factor 1 or PCIF1, which regulates cellular entry through the mediation of N6,2-O-dimethyladenosine (m6Am) activity, an evolutionarily conserved and abundant mRNA modification. The researchers found that PCIF1 promotes the stability of both ACE2 and TMPRSS2 mRNAs, sustaining two key entry factors for SARS-CoV-2 and other coronaviruses."  Their article has recently been published in the Proceedings of the National Academy of Science.  Our congratulations to Gwendolyn and Yinsheng for this recognition of their important work.
