The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics.

    INPUT: Acetyl-11-keto-beta-boswellic acid ( AKBA ) is a naturally occurring pentacyclic triterpene isolated from the gum resin exudate from the stem of the tree Boswellia serrata ( frankincense ) . AKBA has been recently identified as a novel , orally active , non-redox and non-competitive 5-lipoxygenase inhibitor that also inhibits topisomerase I and II in vitro . Because natural pentacyclic triterpenes have an antiproliferative effect against different tumor types , we investigated the effects of AKBA on the proliferation of 11 primary cell cultures established from human surgical specimens of meningiomas , common central nervous system tumors . Treatment of meningioma cells by AKBA revealed a potent cytotoxic activity with half-maximal inhibitory concentrations in the range of 2-8 microM . At similar , physiologically achievable concentrations , AKBA rapidly ( within minutes ) and potently inhibited the phosphorylation of extracellular signal-regulated kinase 1 and 2 ( Erk-1 and Erk-2 ) in meningioma cells stimulated with platelet-derived growth factor BB . High expression level of 5-LO was detected in primary meningioma cells and surgical specimens by immunoblotting analysis , suggesting the possible role of 5-LO in meningioma tumorigenesis . Considering the critical importance of the Erk-1/2 signal transduction pathway not only in meningiomas but in other human neoplasms , the interruption of signaling through this evolutionarily conserved pathway might be one of the mechanisms by which AKBA induces suppression of proliferation and apoptosis of different tumor types .
    OUTPUT:
