| Evidence Level | V |
| Sample | "Young" and "aged" pancreatic cell cultures |
| Peptide(s) Studied | Pancragen |
Key Findings
- Tetrapeptide Pancragen (Lys-Glu-Asp-Trp) stimulated the expression of differentiation factors in both acinar cells and islets of Langerhans cells
- Effects were observed in both "young" and "aged" cell cultures, with the most pronounced effects in aged cultures
- Pancragen promoted expression of markers associated with functional pancreatic cell phenotype
- The peptide appeared to partially restore age-related decline in differentiation marker expression
Study Design
In vitro study using pancreatic cell cultures at different passage numbers ("young" vs. "aged" cultures). Cells were treated with Pancragen and assessed for expression of differentiation markers by immunohistochemistry.
Limitations
- In vitro study using passage-aged cells as an aging model (not true biological aging)
- No functional assessment (e.g., insulin secretion measurement)
- All authors from the Khavinson group
- Published in a journal with limited international impact
- No independent replication
Clinical Relevance
Provides some mechanistic support for Pancragen's proposed pancreatic-supportive activity. However, the in vitro model is very preliminary and does not establish clinical efficacy for diabetes management or pancreatic function.
Methodological Note: This study originates from the Khavinson bioregulation group. Independent replication by Western laboratories is lacking.
