Discovery of potential ferroptosis and osteoporosis biomarkers through TMT proteomics and bioinformatics analysis.
Article in Biomedical engineering online, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPrimary osteoporosis has increasingly emerged as a major issue affecting human health, with a complex specific pathogenic mechanism. As a research hotspot, ferroptosis plays a vital role in the pathogenesis of primary osteoporosis, aiming to explore the link and specific target genes between ferroptosis and primary osteoporosis.
methodsBy utilizing TMT proteomics and bioinformatics analyses, we elucidated the linkages and key targets of the ferroptosis pathway in an ovariectomized osteoporotic rat model. Forty 12-week-old SD female rats were employed in the study, of which 20 female SD rats were ovariectomized as the OVX group and 20 female SD rats were employed as the SHAM group. At the end of the experiments, the femurs of the rats were excised for computed tomography tests and used for hematoxylin and eosin staining. Finally, we extracted bone tissue proteins for TMT proteomics analysis and protein blotting verification.
resultsThe proteomics results of the VX and SHAM groups showed that 133 proteins were significantly changed, of which 91 proteins were upregulated and 42 proteins were downregulated, including TXN, TMSB4X, TFRC, TF, RELA, PARP14, CP, CAPG, and ADIPOQ. The expression of key proteins in the bone tissues was detected by protein blotting. The expression of TFR1, TFRC and TF was upregulated, whereas the expression of Cp, TXN and BMP-2 was downregulated.
conclusionsTMT proteomics and functional enrichment analyses in our study substantiated that in osteoporosis, disturbances in lipid metabolism lead to the emergence of oxidative stress with iron homeostasis imbalance.
