Intervention and comparator
What each group received. Related peptides, analogs and combinations are never treated as the compound itself.
What the authors reported
As stated in the sources. This is the authors’ account, not Peptide Library’s assessment.
Adverse events
None reported. That is not evidence of safety, and how safety was monitored isn’t described.
The authors concluded (paraphrased): Tβ4 and Tβ10 were upregulated in the deep tumor part and associated with Dukes stage and budding grade. The authors suggest both are involved in CRC progression and invasion and are candidate biomarkers and therapy targets.
Peptide Library’s assessment
An automated assessment, made by AI separately from the authors’ conclusions and not reviewed by a person. How risk of bias is assessed.
Limitations
- other: Endogenous tissue levels were measured. Thymosin β4 was not administered to anyone, so the study cannot inform effects of treatment.
- small or imprecise: Tissue samples came from only 18 patients, per the abstract.
- abstract only: Only the PubMed abstract is available in the record. Methods and results detail are limited.
- inappropriate endpoint: Endogenous tissue protein levels are a biomarker measure. No compound was given and no clinical outcomes were assessed.
No risk-of-bias assessment has been published for this study’s results.
Claims this study informs
- Improves dry eye signs and symptoms: not eligible (not primary study) for “Ocular discomfort and corneal staining”
- Is safe for human administration: not eligible (not primary study) for “Adverse events, serious adverse events and discontinuations”

These assessments describe published research. Records marked automated were produced by AI under the published methodology and have not been reviewed by a person; they can contain errors. None of this is medical advice, not a statement about any product’s safety for human use, and not a regulatory approval. Peptide Library’s vendor and partner relationships play no part in them (editorial independence).
