Long noncoding RNA H19 regulates degeneration and regeneration of injured peripheral nerves.
Article in Neural regeneration research, 2023. 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
Our previous studies have shown that long noncoding RNA (lncRNA) H19 is upregulated in injured rat sciatic nerve during the process of Wallerian degeneration, and that it promotes the migration of Schwann cells and slows down the growth of dorsal root ganglion axons. However, the mechanism by which lncRNA H19 regulates neural repair and regeneration after peripheral nerve injury remains unclear. In this study, we established a Sprague-Dawley rat model of sciatic nerve transection injury. We performed in situ hybridization and found that at 4-7 days after sciatic nerve injury, lncRNA H19 was highly expressed. At 14 days before injury, adeno-associated virus was intrathecally injected into the L4-L5 foramina to disrupt or overexpress lncRNA H19. After overexpression of lncRNA H19, the growth of newly formed axons from the sciatic nerve was inhibited, whereas myelination was enhanced. Then, we performed gait analysis and thermal pain analysis to evaluate rat behavior. We found that lncRNA H19 overexpression delayed the recovery of rat behavior function, whereas interfering with lncRNA H19 expression improved functional recovery. Finally, we examined the expression of lncRNA H19 downstream target SEMA6D, and found that after lncRNA H19 overexpression, the SEMA6D protein level was increased. These findings suggest that lncRNA H19 regulates peripheral nerve degeneration and regeneration through activating SEMA6D in injured nerves. This provides a new clue to understand the role of lncRNA H19 in peripheral nerve degeneration and regeneration.
