§ 01 Overview
Overview
Khavinson liver-derived tetrapeptide. Activates ribosomal gene transcription and decondenses heterochromatin in senescent lymphocytes.
Khavinson lab. Limited Western replication.
§ 02 Mechanism
Mechanism of action
Livagen (KEDA) is proposed to activate transcription of ribosomal genes and decondense pericentromeric heterochromatin, which may restore expression in senescent lymphocytes and aged intestinal enzymes.
