Abstract
Backgroud: Pinoresinol (Pin) and pinoresinol monoglucoside (PMG) are plant-derived lignan molecules with multiple functions. We showed previously that an endophytic fungus from Eucommia ulmoides Oliv., Phomopsis sp. XP-8 is able to produce Pin and PMG.
Objective: This study was carried out to test the anti-tumor capability of the culture of XP-8 and identify the major effective compounds. Method: The fungal culture was added in the culture of HepG2 and K562 cells, and the viabilities of these cells were detected and the possible mechanism was analyzed. Result: The fungal culture showed significant capaiblity in decreasing the viability of tumor cells and induce apoptosis via up-regulation of the expression of apoptosis-related genes. It also significantly inhibited the adhesion and migration of HepG2 cells by blocking MMP-9 expression. Pin and PMG were isolated from the growth culture and shown to be the major effective components for inhibition. Conclusion: The study indicated the potential application of XP-8 in the production of anti-tumour products by the bioconversion of glucose.Keywords: Apoptosis, caspase, inhibition effects, pinoresinol, pinoresinol monoglucosid.

Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
