Ganoderenic acid E is a natural product

The main active compounds of GLE were identified by HPLC, EI-MS and NMR, and the compounds related targets were predicted using docking program. To investigate the functions of GL holistically, the whole active components of GL and related targets were predicted based on four public databases. Subsequently, the compound-target network and component-target network were constructed respectively, and they were overlapped to detect the kernel potential targets in both networks. Furthermore, the qRT-PCR was used to validate the expression levels of target genes in GLE treated Hepa1-6-bearing C57 BL/6 mice. In our work, 12 active compounds of GLE were identified, including Ganoderic acid A, Ganoderenic acid A, Ganoderic acid B, Ganoderic acid H, Ganoderic acid C2, ganoderenic acid D, Ganoderic acid D, Ganoderenic acid G, Ganoderic acid Y, Kaemferol, Genistein and Ergosterol. Using the docking program, 20 targets were mapped to 12 compounds of GLE. Furthermore, 122 effective active components of GL and 116 targets were holistically predicted using public databases. Compare with the compound-target network and component-target network, 6 kernel targets were screened, including AR, CHRM2, ESR1, NR3C1, NR3C2 and PGR, which was considered as potential markers and might play important roles in the process of GLE treatment. GLE effectively inhibited tumor growth in Hepa1-6-bearing C57 BL/6 mice. Moreover, qRT-PCR data demonstrated the expression levels of NR3C1, NR3C2 and AR are up-regulated and PGR, ESR1 and CHRM2 are down-regulated.
