One Of The Major compOnents Isolated From The Traditional  2-methyl-1  Chinese Medicine Rubia Yunnanensis  3  Exhibited Inhibitory Activity On The proliferatiOn Of Several  6-trihydroxy-9  HumAn CAncer Cell Lines. The Results From An Annexin V-fitc (fluoresein-5-isothiocyAnate) Apoptosis Assay  10-anthraquinone (Mta)  And Dna Content Analysis Showed That Mta Exerted Cytotoxicity Via Apoptosis Induction And G2/m Cell Cycle  Arrest In Human Cervical carcInoma Hela Cells. Further  Mta Was Found To Induce apopTosis Of Hela Cells  Through The MITochondria-mediated Pathway. It Caused The Translocation Of Bax To The mITochondria And  Release Of Cytochrome c Into The Cytosol  Which Caused The Cleavage Of Caspase And Poly(Adp-ribose)  Polymerase And Finally Triggered The Apoptosis. furThermore  The P53/p21/cdc2-cyclin B1 Signaling Was  Found Related To The G2/m Arrest Caused By Mta. The Over-expression Of P21 And Down-expression Of  Cyclin B1 Caused By Mta Inactivated The cdc2-Cyclin B1 Complex Of G2/m Checkpoint And Finally Caused  The G2/m Arrest In Hela Cells. ThIs Study Demonstrated That Mta Is a Potential Anti-cancer Component Of  R. Yunnanensis  a Folk Anti-cancer Herb Used In Yunnan  China.
