Adipocyte PCPE2 Expression: Links Between Fibrosis and Beiging in White Adipose Tissue

Study overview and title context

The document in the JINA source is a bioRxiv preprint titled “Adipocyte Expression of O-Glycoprotein Procollagen C-Endopeptidase Enhancer Protein 2 (PCPE2): Mechanisms Linking Fibrosis and Beiging of White Adipose Tissue.” The title indicates the manuscript addresses adipocyte expression of PCPE2 and examines mechanisms that may connect fibrosis and beiging processes within white adipose tissue. The source content provided to this editorial summary consists primarily of article metadata and author information; the body of the manuscript (abstract, methods, results, figures, and detailed conclusions) was not included in the supplied content.

Author list and institutional affiliations

The preprint lists multiple contributing authors and their institutional affiliations as provided in the JINA source. Key affiliations and author–institution pairings reported in the source include:

• Medical College of Wisconsin (several authors, including corresponding author Mary G Sorci-Thomas)
• Duke University (authors listed with that affiliation)
• Washington University in St. Louis (authors listed with that affiliation)
• Pohang University of Science and Technology (authors listed with that affiliation)
• Seoul National University (authors listed with that affiliation)
• Yale University (authors listed with that affiliation)

The JINA source contains individual author names tied to these institutions; readers wishing to cite or contact specific contributors should consult the original preprint for the full, authoritative author list and order.

Preprint status, DOI, and correspondence

The manuscript is hosted on bioRxiv and is explicitly identified as a preprint that has not been peer reviewed. The DOI reported in the source is https://doi.org/10.64898/2026.07.24.740318. Correspondence for the manuscript is directed to Mary G Sorci-Thomas (email: msthomas@mcw.edu), with Medical College of Wisconsin listed as her affiliation in the source metadata.

Primary topics signaled by the title (PCPE2, fibrosis, beiging, white adipose tissue)

Based on the article title alone, the work focuses on the following concepts as signaled by the JINA metadata:

• Adipocyte expression of the O-glycoprotein Procollagen C-Endopeptidase Enhancer Protein 2 (PCPE2).
• Mechanistic links between fibrosis and the beiging (i.e., acquisition of brown-like features) of white adipose tissue.

The title implies an investigation of molecular or cellular mechanisms in adipose tissue biology that connect extracellular matrix or fibrotic processes with adipocyte phenotypic changes described as beiging. However, the supplied JINA content does not include experimental descriptions, pathways, or mechanistic results.

Available metadata versus missing manuscript content

The JINA-provided source contains comprehensive bibliographic and author metadata but omits core manuscript elements necessary to evaluate the study’s scientific claims. Specifically, the following were not reported in the supplied source content:

• Abstract and concise summary of aims, hypotheses, and main conclusions.
• Experimental design, methods, and models used (in vitro, in vivo, genetic models, human samples, etc.).
• Results, quantitative data, statistical analyses, and figures or tables.
• Detailed mechanistic descriptions, proposed pathways, or molecular interactions involving PCPE2.
• Discussion of implications, limitations, or clinical/translational relevance beyond what is implied by the title.

Because these elements are absent from the provided material, no domain-specific results, effect sizes, or mechanistic assertions can be restated here without access to the full preprint.

Implications, limitations, and recommended next steps for readers

Implications:

• The title indicates the manuscript may present data relevant to adipose tissue remodeling, extracellular matrix biology, and adipocyte phenotype regulation via PCPE2, with potential relevance to metabolic physiology and tissue fibrosis.

Limitations of this summary:

• This editorial rewrite is limited to the bibliographic and author metadata available in the JINA source. The absence of the abstract, methods, results, and discussion in the supplied content prevents summarizing or evaluating the study’s evidence, methodology, or conclusions.

Recommended next steps for readers interested in the study:

• Consult the full preprint at the DOI provided (https://doi.org/10.64898/2026.07.24.740318) or the bioRxiv page to read the complete manuscript, including methods, data, and authors’ interpretation.
• Note the preprint status: findings have not been peer reviewed. For clinical or translational application, await peer review and, where available, corroborating studies.
• Contact the corresponding author (msthomas@mcw.edu) for clarifications or requests for data/tools if needed and appropriate.

Conclusion

The JINA source supplies full citation and author metadata for a bioRxiv preprint investigating adipocyte PCPE2 expression and its proposed mechanistic links to fibrosis and beiging in white adipose tissue, but does not include experimental content or results. Readers should review the full preprint for substantive scientific details and interpretation.
