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: AMP-activated protein kinase ( AMPK ) has been implicated in anti-proliferative actions in a range of cell systems . Recently , it was observed that Compound C , an inhibitor of AMPK , also reduced the cell viability in human diploid fibroblasts ( HDFs ) . Compound C-induced growth arrest was associated with a decrease in the cell cycle regulatory proteins , such as proliferating cell nuclear antigen , phosphorylated pRB , cyclin-dependent protein kinases ( Cdk 2 and 4 ) , cyclins ( D and E ) , and the Cdk inhibitors ( p21 , p16 , and p27 ) . Therefore , the present study examined the molecular mechanism of the antiproliferative effects of Compound C. Although Compound C inhibited serum-induced phosphorylation of Akt and its substrate , glycogen synthase kinase-3Î² , it did not affect the Akt activity in vitro . Compound C significantly inhibited the receptor tyrosine phosphorylation and the activity of downstream signaling molecules , such as p85 phosphoinositide 3-kinase , phospholipase C-Î³1 , and extracellular signal-regulated kinase 1/2 , induced by platelet-derived growth factor ( PDGF ) but not by epidermal growth factor- and insulin-like growth factor . In vitro growth factor receptor tyrosine kinase activity profiling revealed the IC(50) for PDGF receptor-Î² ( PDGFRÎ² ) to be 5.07 Î¼M , whereas the IC(50) for the epidermal growth factor receptor and insulin-like growth factor receptor was â¥100 Î¼M . The inhibitory effect of Compound C on PDGFRÎ² and Akt was also observed in AMPKÎ±(1)/Î±(2)-knockout mouse embryonic fibroblasts , indicating that its inhibitory effect is independent of the AMPK activity . The inhibitory effect of Compound C on cell proliferation and PDGFRÎ² tyrosine phosphorylation was also demonstrated in various PDGFR-expressing cells , including MRC-5 , BEAS-2B , rat aortic vascular smooth muscle cells , and A172 glioblastoma cells . These results indicate that Compound C can be used as a potential antiproliferative agent for PDGF- or PDGFR-associated diseases , such as cancer , atherosclerosis , and fibrosis .
