Abstract

Polyunsaturated fatty acids (PUFAs) are important molecules for human health. We investigated the effects of three major omega-3 PUFAs on C2C12 myoblast proliferation. Both docosahexaenoic (DHA) and eicosapentaenoic (EPA) acids decreased cell growth, whereas linolenic (ALA) acid did not, compared with the control. Cell cycle analysis showed that G(1) phase duration was increased markedly and S-phase duration was decreased by DHA and EPA. In contrast, there was no change in the G(1) or S-phase duration when the cells were treated with linolenic acid. To determine how DHA and EPA affected the cell cycle, cyclins and MAPK proteins were investigated. Western blotting and real-time quantitative PCR showed that DHA and EPA decreased cyclin E and CDK2 levels at both the protein and mRNA level. Also, MAPK phosphorylation levels were decreased by treatment with DHA and EPA. Our results indicated that different kinds of n-3 PUFA differentially affected myoblast cell proliferation. DHA and EPA decreased skeletal muscle cell proliferation through a mechanism involving MAPK-ERK.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
