Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain. ACS cannot be held responsible for errors or consequences arising from the use of information contained in these “Just Accepted” manuscripts.

ABSTRACT

22

Bioactive peptides derived from foods have shown beneficial anti-inflammatory

potential. Inhibitory κB kinase-β (IKKβ) plays a crucial role on the activation of

24

nuclear factor-κB (NF-κB), a transcription factor involved in inflammation. Here we

25

applied proteomic and bioinformatics approaches to identify anti-inflammatory

peptides that target IKKβ from corn silk. Corn silk extract significantly suppressed

lipopolysaccharide (LPS)-induced NF-κB activities (1.7±0.2 fold vs. 3.0±0.6 fold,
