Composite fatty acid ether amides suppress growth of liver cancer cells in vitro and in an in vivo allograft mouse model.
Article in Cellular oncology (Dordrecht, Netherlands), 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe heterogeneity of liver cancer, in particular hepatocellular carcinoma (HCC), portrays the requirement of multiple targets for both its treatment and prevention. Multifaceted agents, minimally or non-toxic for normal hepatocytes, are required to address the molecular diversity of HCC, including the resistance of putative liver cancer stem cells to chemotherapy.
methodsWe designed and synthesized two fatty acid ethers of isopropylamino propanol, C16:0-AIP-1 and C18:1-AIP-2 (jointly named AIPs), and evaluated their anti-proliferative effects on the human HCC cell line Huh7 and the murine hepatoma cell line BNL 1MEA.7R.1, both in vitro and in an in vivo allograft mouse model.
resultsWe found that AIP-1 and AIP-2 inhibited proliferation and caused cell death in both Huh7 and BNL 1MEA.7R.1 cells. Importantly, AIP-1 and AIP-2 were found to block the activation of putative liver cancer stem cells as manifested by suppression of clonal 'carcinosphere' development in growth factor-free and anchorage-free medium. The AIPs exhibited a relatively low toxicity against normal human or rat hepatocytes in primary cultures. In addition, we found that the AIPs utilized multifaceted pathways that mediate both autophagy and apoptosis in HCC, including the inhibition of AKTs and CAMK-1. In immune-competent mice, the AIPs significantly reduced BNL 1MEA.7R.1 cell-driven tumor allograft development, with a higher efficiency than sorafenib. A combination of AIP-1 + AIP-2 was most effective in reducing the tumor allograft incidence.
conclusionsAIPs represent a novel class of simple fatty acid derivatives that are effective against liver tumors via diverse pathways. They show a low toxicity towards normal hepatocytes. The addition of AIPs may represent a new avenue towards the management of chronic liver injury and, ultimately, the prevention and treatment of HCC.
