ZEB1 regulates bone metabolism in osteoporotic rats through inducing POLDIP2 transcription.
Article in Journal of orthopaedic surgery and research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundOsteoporosis (OP) is a common metabolic bone disease mainly involving bone remodeling and blood vessels. The current study aimed to explore the role of zinc finger E-box binding homeobox 1 (ZEB1) in OP.
methodsFirst, gene expression microarrays for OP were downloaded from the Gene Expression Omnibus database and analyzed to screen for potential targets. Subsequently, a rat OP model was constructed using ovariectomy (OVX), and osteoblastic and osteoclastic differentiation and alterations in osteoporotic symptoms were observed upon intraperitoneal injection of oe-ZEB1 lentiviral vectors. DNA polymerase delta interacting protein 2 (POLDIP2) was predicted to be a downstream target of ZEB1, which was validated by ChIP-qPCR and dual-luciferase experiments. RAW264.7 cells were subjected to lentiviral vector infection of oe-ZEB1 and/or sh-POLDIP2, followed by RANKL treatment to induce osteoclast differentiation.
resultsZEB1 was poorly expressed in blood samples of postmenopausal patients with OP and in bone tissues of OVX-treated rats. Overexpression of ZEB1 or POLDIP2 in OVX rats promoted osteoblastogenesis and inhibited osteoclast differentiation. In RANKL-treated RAW264.7 cells, the transcription factor ZEB1 enhanced the expression of POLDIP2, and silencing of POLDIP2 attenuated the inhibitory effect of oe-ZEB1 on the differentiation of macrophages RAW264.7 to osteoclasts.
conclusionsZEB1 promotes osteoblastogenesis and represses osteoclast differentiation, ultimately reducing the occurrence of postmenopausal OP by elevating the expression of POLDIP2.
