Proteomic and metabolomic analysis of Nothapodytes nimmoniana (J. Graham) extracts’ treatment on HeLa cells

Nothapodytes nimmoniana is a natural source of camptothecin, a known anticancer drug. Stem and leaf extracts of Nothapodytes nimmoniana were studied to assess its in vitro action on cancer progression events in a cervical cancer cell line, the HeLa. As a well-studied ideal model system, the HeLa has been chosen and the effects of extracts on cancer progression events have been traced out. HeLa cells and media samples were analyzed for differentially expressed proteins and metabolites respectively on RRLC–ESI-QTOFMS. The CBFA2T1, cysteine-rich protein 2-binding protein, Zinc finger protein 788, transcription factor RFX3 and angiomotin-like protein 1 were significantly expressed proteins while 3-hydroxysuberic acid, indole-3-carboxylic acid, N8-acetylspermidine and l-octanoylcarnitine were significantly expressed metabolites. Aminoacyl-tRNA biosynthesis, purine metabolism, and valine, leucine, arginine, proline metabolism were the most prominent pathways. The multi-omics approach has the greatest metabolites and proteins profiling potential, hence was applied here to find signatures of N. nimmoniana extracts’ treatment of cervical cancer.
