Researchers Correct Study on Cysteine-Linked Weight Loss After Discovering Copy Error

Researchers at the NYU Grossman School of Medicine have made a correction to a recent study published in the journal Nature. The correction involves a copy-paste error in Extended Data Fig. 2f,g, which has since been updated with the correct panels in both the HTML and PDF versions of the article. According to the correction notice, the error involved the incorrect panels for Day 3 Het No Cys and Day 3 KO Ctrl, which were mistakenly swapped. The mistake did not affect the conclusions of the figure or the overall paper, according to the researchers. The study, which was published on May 21, 2025, explored the effects of cysteine deficiency on fat metabolism and weight loss. "We are pleased to correct this minor error and ensure the accuracy of our research," said Alan Varghese, one of the authors of the study. "Our findings on the role of cysteine in fat metabolism and weight loss remain unchanged, and we are confident in the validity of our results." The study, which involved a team of researchers from the Department of Cell Biology and the Department of Biochemistry and Molecular Pharmacology at NYU Grossman School of Medicine, used a combination of metabolomics and mitochondrial analysis to investigate the effects of cysteine deficiency on fat metabolism and weight loss. Cysteine is an essential amino acid that plays a critical role in various biological processes, including fat metabolism and energy production. The study's findings have important implications for our understanding of the role of cysteine in human health and disease. The correction to the study is a minor one, and it does not affect the overall conclusions of the research. The study's authors are confident in the validity of their results and are continuing to explore the role of cysteine in fat metabolism and weight loss. In related news, researchers continue to study the effects of cysteine deficiency on human health, with a focus on developing new treatments for metabolic disorders. The study's findings have sparked interest in the scientific community, and further research is needed to fully understand the role of cysteine in human health and disease. As of now, the corrected version of the study is available online, and the researchers are continuing to work on further studies to explore the role of cysteine in fat metabolism and weight loss.
