First, the advent of highly sensitive fluorescent (bio)chemicals revealed cellular pools of zinc ions involved in signaling and secretion from cells for paracrine, autocrine, and possibly endocrine functions. Zinc signaling adds a yet unaccounted number of targeted proteins to the already impressive number of zinc proteins. Second, cellular zinc concentrations are remarkably high in the order of the concentrations of major metabolites and, therefore, at the cellular level zinc is not a trace element. Zinc is also not an antioxidant because zinc ions are redox-inactive in biology. However, zinc can express indirect pro-oxidant or proantioxidant effects depending on how cellular zinc is buffered. Zinc sites in proteins and other biomolecules can become redox-active when zinc is bound to the redox-active sulfur donor atom of cysteine. This interaction links zinc and redox metabolism, confers mobility on tightly bound zinc, and has implications for treating zinc deficiency. Third, the concept of zinc deficiency in blood as the only measure of an inadequate zinc status needs to be extended to zinc dyshomeostasis in cells because overwhelming the mechanisms controlling cellular zinc homeostasis can result in either not enough or too much available zinc. We need additional biomarkers of zinc status that determine cell-specific changes and perturbations of the system regulating cellular zinc, including functional deficits, and address the multiple genetic and environmental factors that can cause a conditioned zinc deficiency or overload. Considering the wider context of altered zinc availability in different organs, cells, and organelles impinges on whether zinc supplementation will be efficacious and adds another dimension to the already high health burden of zinc deficiency and its sequelae worldwide.</div></div>","PeriodicalId":16620,"journal":{"name":"Journal of Nutrition","volume":"155 3","pages":"Pages 669-675"},"PeriodicalIF":3.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142950488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dr. Salim has responded to JN by stating that the paper was part of a collaborative study with two other laboratories conducted more than 10 years ago. Both laboratories were shut down due to the death of one leader and the retirement of the other. In addition, Dr. Salim has changed her research directions, and her laboratory was relocated, resulting in misplaced or lost research record. Thus, she was unable to supply any of the requested original image files. Instead, she has indicated that similar protein expression profiles among the hippocampus, amygdala, and prefrontal cortex as shown in the figures were caused by their similar vulnerabilities and responses to oxidative stress induced by the pro-oxidant drug treatments and the multiple uses of the same blots for probing and re-probing different proteins.&lt;/div&gt;&lt;div&gt;However, the editorial board of JN (with the aid of image analysis software), solicited experts, and external professionals are not convinced that the explanations given by the corresponding author can address the above-described issues in Figures 5, 6, and 7 of the paper.&lt;/div&gt;&lt;div&gt;In light of the concerns affecting multiple figure panels that question the reliability of these data, The Journal of Nutrition's Editor retracts this article.
