Fourier Transform Infrared Spectroscopic Characterization of Aortic Wall Remodeling by Stable Gastric Pentadecapeptide BPC 157 After Unilateral Adrenalectomy in Rats.

Researchers used Fourier Transform Infrared Spectroscopy to examine how the peptide BPC 157 affected aortic wall composition and structure in rats that underwent unilateral adrenalectomy (removal of one adrenal gland). The study identified specific changes in protein and collagen organization within the aortic tissue following BPC 157 treatment compared to control animals. **Evidence level: Animal model (rat study).**

Safranal-Standardized Saffron Extract Improves Metabolic, Cognitive, and Anxiolytic Outcomes in Aged Mice via Hypothalamic-Amygdalar Peptide Modulation.

This animal model study investigated safranal-standardized saffron extract in aged mice, examining its effects on metabolic function, cognitive performance, and anxiety-related behaviors through changes in hypothalamic-amygdalar peptide signaling. Researchers found that the saffron extract improved metabolic markers, cognitive outcomes, and anxiolytic (anxiety-reducing) measures in aged mice, with these improvements associated with modulation of peptides in brain regions involved in metabolism, learning, and emotional regulation. This is evidence-level animal model research that does not directly translate to human outcomes.

Inflammation-triggered self-immolative conjugates enable oral peptide delivery by overcoming gastrointestinal barriers.

Research Summary

Researchers developed inflammation-triggered self-immolative conjugates designed to deliver peptides orally by protecting them from gastrointestinal degradation and enhancing intestinal absorption in an animal model. The conjugates were engineered to release their peptide payload specifically in response to inflammatory markers present in the gastrointestinal tract, potentially enabling oral administration of peptides like KPV that are normally destroyed by stomach acid and digestive enzymes. This is an animal model study published in *Science Advances*.

Tracheocutaneous Fistula Resolved by Pentadecapeptide BPC 157 Therapy Through the NO-System-Triple NO-Agent Approach in Rats.

This animal model study in rats investigated whether the peptide BPC 157 could resolve tracheocutaneous fistulas (abnormal passages between the trachea and skin) through mechanisms involving the nitric oxide (NO) system. Researchers found that BPC 157 treatment promoted fistula healing and closure, with evidence suggesting involvement of three NO-related pathways. This is an animal model study and does not represent human clinical evidence.
