Application

3-Methyladenine (3-MA) is used to inhibit and study the mechanism of autophagy (lysosomal self-degradation) and apoptosis under various conditions. 3-MA inhibits autophagy by blocking autophagosome formation via the inhibition of type III Phosphatidylinositol 3-kinases (PI-3K). For use as an autophagy inhibitor, 3-MA is typically used at a concentration of 5 mM.
3-Methyladenine has been used as an autophagy inhibitor:
  • to determine the expressions of autophagy-related genes (Beclin 1, light chain 3 (LC3) and p62) using the transfected human bone marrow mesenchymal stem cells (BM-MSCs)
  • with cisplatin to study the inhibition of autophagy influenced cisplatin-induced apoptosis in A2780cp cells
  • to study the interplay between colistin-induced autophagy and apoptosis

Standard for detection of nucleic acid methylation during carcinogenesis.

Staphylococcus aureus is an important pathogen causing chronic and subclinical mastitis of cows. Autophagy is an important regulatory mechanism that participates in the elimination of invading pathogenic organisms. Here, we hypothesize that autophagy is involved in the process of Staph.
