1 · What the graph read from it

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.

2 · The registry

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

Transient receptor potential melastatin 8 (TRPM8) and transient receptor potential vanilloid 1 (TRPV1) are ion channels that detect cold and hot sensations, respectively. Their activation depolarizes the peripheral nerve terminals resulting in action potentials that propagate to brain via the spinal cord. These receptors also play a significant role in synaptic transmission between dorsal root ganglion (DRG) and dorsal horn (DH) neurons. Here, we show that TRPM8 is functionally downregulated by activation of protein kinase C (PKC) resulting in inhibition of membrane currents and increases in intracellular Ca2+ compared with upregulation of TRPV1 in cloned and native receptors. Bradykinin significantly downregulates TRPM8 via activation of PKC in DRG neurons. Activation of TRPM8 or TRPV1 at first sensory synapse between DRG and DH neurons leads to a robust increase in frequency of spontaneous/miniature EPSCs. PKC activation blunts TRPM8- and facilitates TRPV1-mediated synaptic transmission. Significantly, downregulation is attributable to PKC-mediated dephosphorylation of TRPM8 that could be reversed by phosphatase inhibitors. These findings suggest that inflammatory thermal hyperalgesia mediated by TRPV1 may be further aggravated by downregulation of TRPM8, because the latter could mediate the much needed cool/soothing sensation.
