Identification of essential genes for Acanthamoeba castellanii excystation during encystation and excystation.
Article in Parasites, hosts and diseases, 2024. 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
Acanthamoeba is an opportunistic pathogen that causes Acanthamoeba keratitis, granulomatous amoebic encephalitis, and other cutaneous diseases. The life cycle of Acanthamoeba consists of 2 stages of trophozoites and cysts. Under adverse environmental conditions, Acanthamoeba encysts, while the conditions become favorable for growth, it reverts to the trophozoite form. Acanthamoeba excystation is crucial for its proliferation and can lead to recurrent infections after incomplete treatment. To identify the factors involved in excystation, A. castellanii was subjected to either encystation- or excystation-inducing conditions, and gene expression profiles were compared using mRNA sequencing. A. castellanii samples were collected at 8 h intervals for analysis under both conditions. Differentially expressed gene analysis revealed that 1,214 and 1,163 genes were upregulated and downregulated, respectively, by more than 2-fold during early excystation. Five genes markedly upregulated in early excystation (ACA1_031140, ACA1_032330, ACA1_374400, ACA1_275740, and ACA1_112650) were selected, and their expression levels were confirmed via real-time PCR. Small interfering RNA (siRNA) targeting these 5 genes was transfected into Acanthamoeba and gene knockdown was validated through real-time PCR. The silencing of ACA1_031140, ACA1_032330, ACA1_374400, and ACA1_112650 inhibited excystation and suggested that these genes might be essential for excystation. Our findings provide valuable insights for suppressing Acanthamoeba proliferation and recurrence.
