Transcriptomic and proteomic studies of condylar ossification of the temporomandibular joint in porcine embryos.

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
backgroundThe ossification mechanism of the temporomandibular joint (TMJ) condyle remains unclear in human embryo. The size and structure of TMJ, shape of articular disc and the characteristics of omnivorous chewing in the pig are similar to those of humans. The pig is an ideal animal for studying the mechanism of ossification of the TMJ condyle during the embryonic period.
methodIn a previous study by our group, it was found that there was no condylar ossification on embryonic day(E) 45, but the ossification of condyle occurred between E75 and E90. In this study, a total of 12 miniature pig embryos on E45 and E85 were used. Six embryos were used for tissue sections (3 in each group). The remaining six embryos were used for transcriptomic and proteomic studies to find differential genes and proteins. The differentially expressed genes in transcriptome and proteomic analysis were verified by QPCR.
resultsIn total, 1592 differential genes comprising 1086 up-regulated genes and 506 down-regulated genes were screened for fold changes of ≥2 to ≤0.5 between E45 and E85. In the total of 4613 proteins detected by proteomic analysis, there were 419 differential proteins including 313 up-regulated proteins and 106 down-regulated proteins screened for fold changes of ≥2 to ≤0.5 between E45 and E85. A total of 36 differential genes differing in both transcriptome and proteome analysis were found. QPCR analysis showed that 14 of 15 selected genes were consistent with transcriptome analysis.
conclusionCondylar transcriptome and proteomic analysis during the development of TMJ in miniature pigs revealed the regulatory genes/proteins of condylar ossification.
