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.

ABSTRACT

2

Previous studies have shown that short-chain fatty acids (SCFAs) are capable of

3

decreasing plasma cholesterol. However, the relative plasma cholesterol-lowering activity of

4

individual SCFAs and the underlying mechanisms by which SCFAs decrease plasma cholesterol

5

remain largely unknown. The present study was to compare plasma cholesterol-lowering

6

potency of four common SCFAs with 2-5 carbons, and to investigate their interactions with

7

gene expressions of key regulatory factors involved in cholesterol metabolism. Five groups of

8

male Golden hamsters were fed either a high cholesterol control diet (HCD) or one of the four

9

experimental HCD diets containing 0.5 mol/kg diet of acetate (Ac), propionate (Pr), butyrate

10

(Bu), and valerate (Va), respectively, for 6 weeks. Results showed that Ac, Pr, and Bu

11

significantly reduced plasma total cholesterol (TC) by 24%, 18%, and 17% (p
