Inhibition of induced-hepatic cancer
Article in Frontiers in oncology, 2022. 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
Background: Liver cancer is the deadliest malignancy among common tumors. It is the top cause of cancer-related deaths in Egypt, and it is characterized by increasing occurrence among the population. The objective of this study was to determine the outcome of pre-treatment of IQGAP1-shRNA on induced mouse hepatocellular carcinoma model and evaluate the potency of this IQGAP1-shRNA plasmid to recover hepatic cancer as a new tool of cancer therapy. Therefore, we will use RNA interference (RNAi) technology to silence IQGAP1 oncogene to completely recover the chemically induced models for hepatic cancer by designing short RNAi specific for IQGAP1 gene in HCC cells Results: Our results revealed that the treated group with IQGAP1-shRNA with DENA developed very few cases of hepatic cancer when compared with the positive control group. The positive control group exhibited significant increases in the liver function level as well as a decrease in serum albumin levels when compared to both the treated and the negative control groups. The altered levels of the serum α-fetoprotein as well as of the tumor necrosis factor-alpha, and interleukin-4 in DENA-treated mice were significantly ameliorated by IQGAP1-shRNA administration. Flow cytometer analyses have indicated that the silencing of IQGAP1 cannot significantly modulate DENA-induced apoptosis in the circulating blood cells. Moreover, the elevated mRNA expression levels of IQGAP1, IQGAP3, KRas, HRas, interleukin-8, nuclear factor kappa B, caspase-3, caspase-9 and Bcl-2, were significantly decreased by the IQGAP1-shRNA treatment. However, the IQGAP2, DR4, DR5, p53 and BAX genes were found to be significantly up-regulated post-therapy. In agreement with these findings, IQGAP1-shRNA was able to modulate the DENA-induced histological changes in the mice liver which were represented by severe necrosis and hydropic degenerative changes. Conclusion: Our study revealed that IQGAP1-shRNA was able to preserve hepatocyte integrity and the liver histological architecture through the regulation of the expression of IQGAPs, Ras, TRAILs and IL-8 receptors, as well as of pro-apoptotic and anti-apoptotic genes. Therefore, the silencing of IQGAP1 could be part of a promising therapeutic strategy against hepatic cancer.
