Toxoplasma gondii profilin and tachyzoites RH strain may manipulate autophagy via downregulating Atg5 and Atg12 and upregulating Atg7.
Article in Molecular biology reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundAutophagy process is an important defense mechanism against intracellular infection. This process plays a critical role in limiting the development of Toxoplasma gondii. This study aimed to investigate the effects of T. gondii profilin and tachyzoites on the expression of autophagy genes. METHODS AND
resultsPMA-activated THP-1 cell line was incubated with T. gondii profilin and tachyzoites for 6 h. After RNA extraction and cDNA synthesis, the expression of Atg5, Atg7, Atg12, and LC3b was evaluated using real-time PCR. The results revealed statistically significant downregulation of Atg5 for 1.43 (P-value = 0.0062) and 4.15 (P-value = 0.0178) folds after treatment with T. gondii profilin and tachyzoites, respectively. Similar to Atg 5, Atg 12 revealed a statistically significant downregulation for profilin (1.41 fold; P-value = 0.0047) and T. gondii tachyzoites (3.25 fold; P-value = 0.011). The expression of Atg7 elevated in both T. gondii profilin (2.083 fold; P-value = 0.0087) and tachyzoites (1.64 fold; P-value = 0.206). T. gondii profilin and tachyzoites downregulated (1.04 fold; P-value = 0.0028) and upregulated (twofold; P-value = 0.091) the expression of LC3b, respectively.
conclusionsOur findings suggest that T. gondii and profilin may manipulate autophagy via preventing from the formation of Atg5-12-16L complex to facilitate replication of T. gondii and development of toxoplasmosis.
