Anticancer activity of Helicobacter pylori ribosomal protein (HPRP) with iRGD in treatment of colon cancer.

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
purposeAs the conventional therapeutic approaches were not completely successful in the treatment of colon cancer, there is still a need for finding the most efficient therapeutic agents. Here we investigated the anticancer activity of HPRP-A1 that was derived from the N-terminal region of Helicobacter pylori ribosomal protein L1 (RpL1) alone or in combination with tumor-homing peptide iRGD and 5-Fluorouracil (5FU) on colon cancer cell lines (CT26 and HT29) and isograft models of colon cancer.
methodWe assessed the tumor growth inhibitory activity of HPRP-A1 with or without iRGD and 5FU on colon cancer in vitro and in vivo. In the in vitro part, we investigate the effect of HPRP-A1 alone and in combination with iRGD/5FU.
resultsOur results demonstrated that co-administration of HPRP-A1 with iRGD increased the apoptosis, while these two peptides in combination with 5FU increased the intracellular level of p53 that upregulate the pro-apoptotic gene BAX and downregulate the anti-apoptotic gene BCL2. HPRP-A1 blocks the cell cycle progression in G0/G1. Co-administration of two peptides significantly reduced the size and weight of the tumors, while the group that received 5FU in combination with the peptides increased the necrotic and decrease the fibrotic area significantly in the tumor tissues, which also disrupt the oxidant/antioxidant balance.
conclusionsOur results indicated that HPRP-A1 could be considered an effective agent toward colon cancer in vitro and in vivo with the ability to enhance the effects of conventional chemotherapy agent 5FU.
