Abstract

OBJECTIVE: In white adipose tissue, adipocytes and adipocyte precursor cells are enmeshed in a dense network of type I collagen fibrils. The fate of this pericellular collagenous web in diet-induced obesity, however, is unknown. This study seeks to identify the genetic underpinnings of proteolytic collagen turnover and their association with obesity progression in mice and humans. RESEARCH DESIGN AND METHODS: The hydrolysis and degradation of type I collagen at early stages of high-fat diet feeding was assessed in wild-type or MMP14 (MT1-MMP)-haploinsufficient mice using immunofluorescent staining and scanning electron microscopy. The impact of MMP14-dependent collagenolysis on adipose tissue function was interrogated by transcriptome profiling with cDNA microarrays. Genetic associations between MMP14 gene common variants and obesity or diabetes traits were examined in a Japanese cohort (n = 3,653). RESULTS: In adult mice, type I collagen fibers were cleaved rapidly in situ during a high-fat diet challenge. By contrast, in MMP14 haploinsufficient mice, animals placed on a high-fat diet were unable to remodel fat pad collagen architecture and display blunted weight gain. Moreover, transcriptional programs linking type I collagen turnover with adipogenesis or lipogenesis were disrupted by the associated decrease in collagen turnover. Consistent with a key role played by MMP14 in regulating high-fat diet–induced metabolic programs, human MMP14 gene polymorphisms located in proximity to the enzyme's catalytic domain were closely associated with human obesity and diabetes traits. CONCLUSIONS: Together, these findings demonstrate that the MMP14 gene, encoding the dominant pericellular collagenase operative in vivo, directs obesogenic collagen turnover and is linked to human obesity traits.

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.
