Unlocking vinpocetine's oncostatic potential in early-stage hepatocellular carcinoma: A new approach to oncogenic modulation by a nootropic drug.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The development of new drugs for the inhibition of hepatocellular carcinoma (HCC) development and progression is a critical and urgent need. The median survival rate for HCC patients remains disappointingly low. Vinpocetine is a safe nootropic agent that is often used to enhance cognitive function. The impact of vinpocetine on HCC development and progression has not been fully explored. Our main objective was to investigate the possible inhibitory role of vinpocetine in rats exposed to diethylnitrosamine. We observed that vinpocetine increased the survival rate of these rats and improved the ultrastructure of their livers. Additionally, vinpocetine reduced the liver weight index, mitigated liver oxidative stress, and improved liver function. In both in vitro and in vivo settings, vinpocetine demonstrated antiproliferative and apoptotic properties. It downregulated the expression of CCND1 and Ki-67 while exhibiting anti-BCL-2 effects and enhancing the levels of Bax and cleaved caspase-3. Vinpocetine also successfully deactivated NF-κB, STAT3, and HIF-1α, along with their associated transcription proteins, thereby exerting anti-inflammatory and anti-angiogenic role. Furthermore, vinpocetine showed promise in reducing the levels of ICAM-1 and TGF-β1 indicating its potential role in tissue remodeling. These findings strongly suggest that vinpocetine holds promise as a hepatoprotective agent by targeting a range of oncogenic proteins simultaneously. However, further approaches are needed to validate and establish causal links between our observed effects allowing for a more in-depth exploration of the mechanisms underlying vinpocetine's effects and identifying pivotal determinants of outcomes.
