1 · What the graph read from it

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.

2 · The registry

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

Although we have shown earlier that aldose reductase (AR) inhibitors prevent colorectal cancer cell (CRC) growth in culture as well as in nude mice xenografts, the mechanism(s) is not well understood. In this study, we have investigated how AR inhibition prevents CRC growth by regulating the mitochondrial biogenesis via Nrf2/HO-1 pathway. Incubation of CRC cells such as SW-480, HT29, and HCT116 with AR inhibitor, fidarestat that non-covalently binds to the enzyme, increases the expression of Nrf2. Further, fidarestat augmented the EGF-induced expression of Nrf2 in CRC cells. Fidarestat also increased the Nrf2 -DNA binding activity as well as expression of HO-1 and NQO1 and activation of SOD and catalase in SW480 cells. Similarly, in nude mice xenograft tumor tissues, Nrf2 and HO-1 levels were significantly higher in fidarestat-treated mice compared to controls. Further, stimulation of CRC cells with EGF in the presence of fidarestat increased the mRNA levels of PGC-1α, Nrf1 and TFAM and protein levels of PGC-1α, TFAM and COX-IV and decreased the mitochondrial DNA damage as measured by 8-hydroxy-2'-deoxyguanosine levels. AR inhibitor also modulated the phosphorylations of AMPK and mTOR and expression of p53 in EGF-treated cells. Collectively, our results indicate that AR inhibitor prevents CRC growth by increasing mitochondrial biogenesis via increasing the expression of Nrf2/HO-1/AMPK/p53 and decreasing the mitochondrial DNA damage.
