Intrathecal siRNA against GPNMB attenuates nociception in a rat model of neuropathic pain.
Article in Journal of molecular neuroscience : MN, 2015. 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
Neuropathic pain is characterized by hyperalgesia, allodynia, and spontaneous pain. Recent studies have shown that glycoprotein nonmetastatic melanoma B (GPNMB) plays a pivotal role in neuronal survival and neuroprotection. However, the role of GPNMB in neuropathic pain remains unknown. The aim of the present study was to assess the role of GPNMB in neuropathic pain. In cultured spinal cord neurons, we used two small interfering RNAs (siRNAs) targeting the complementary DNA (cDNA) sequence of rat GPNMB that had potent inhibitory effects on GPNMB, and siRNA1-GPNMB was selected for further in vivo study as it had the higher inhibitory effect. After sciatic nerve injury in rats, the endogenous level of GPNMB was increased in a time-dependent manner in the spinal cord. Furthermore, the intrathecal injection of siRNA1-GPNMB inhibited the expression of GPNMB and pro-inflammatory factors (TNF-α, IL-1β, and IL-6) and alleviated mechanical allodynia and thermal hyperalgesia in the chronic constriction injury (CCI) model of rats. Taken together, our findings suggest that siRNA against GPNMB can alleviate the chronic neuropathic pain caused by CCI, and this effect may be mediated by attenuated expression of TNF-α, IL-1β, and IL-6 in the spinal cord of CCI rats. Therefore, inhibition of GPNMB may provide a novel strategy for the treatment of neuropathic pain.
