Key takeaways
Pancragen is the synthetic tetrapeptide Lys-Glu-Asp-Trp (KEDW; amide form H-Lys-Glu-Asp-Trp-NH₂ in school writing), framed for pancreatic differentiation.
Tarnovskaya and Benberin (2013) report KEDW increasing expression of pancreatic differentiation factors (Ptf1a, Ngn3, Pdx1, Pax6, Foxa2, Nkx2.2, Pax4) in ageing pancreatic cell cultures.
Most retrieval noise is pancreatin enzyme hydrolysate literature. This page filters to the peptide trail.
What it is
Pancragen is the synthetic KEDW tetrapeptide from the Khavinson pancreatic line. Multipolar development includes Tarnovskaya-Benberin work at the Institute of Gerontology, Almaty.
It is not pancreatin. Enzyme hydrolysate papers that share search tokens are dropped.
Registry confusion with testagen historically mis-attributed KEDW; this archive keeps KEDW on pancragen.
What the literature describes
Themed chapters drawn only from papers already mapped on this dossier. Archive map. No medical advice.
Pancreatic differentiation factor expression
The cleanest mapped mechanism is KEDW upregulation of pancreatic differentiation transcription factors in ageing pancreatic cell cultures (Tarnovskaya-Benberin 2013). Russian titles on peptidergic regulation of pancreatic function in age-related pathology sit beside that frame.
Proliferotrope titles on immune organs and short-peptide plus amino-acid combinations in organotypic culture place KEDW in the wider synthetic peptide family. The pancreatic gene map stays primary.
Usable trail: Almaty pancreatic gene-expression work plus peptidergic pancreas ageing titles. Pancreatin / whey hydrolysate chips dominate noise.
PubMed rows from the prior map need checking for pancreatin bleed; curated list keeps peptide-bioregulator hooks where possible.
Open limits
Is KEDW present in natural pancreas extracts, or purely synthetic?
Independent replication outside Tarnovskaya-Benberin remains thin in our map.
Diabetes clinical translation under the pancragen name is not established in the mapped set.
