Deletion of the Transient Receptor Potential Melastatin 2 Gene Mitigates the 6-Hydroxydopamine-Induced Parkinson's Disease-Like Pathology.
Article in Molecular neurobiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Pharmacological inhibition of the transient receptor potential melastatin 2 (TRPM2), an oxidative stress-activated calcium channel, was previously reported to be protective in Parkinson's disease (PD). However, the inhibitors used were not TRPM2 specific, so the involvement of this channel in PD remains unclear. Here, for the first time, Trpm2 partial (+ / -) and complete (- / -) knockout mice underwent stereotaxic surgery for PD induction. Six-hydroxydopamine was injected in the right striatum. On days 3 and 6, motor behavior tests (cylinder, apomorphine, and pole test) were performed. On day 7, brains were collected for dopaminergic neuron immunostaining. Our results showed that Trpm2 + / - male and female mice had reduced motor impairment and dopaminergic neuron death after PD induction. In addition, Trpm2 - / - male and female mice showed absent or lesser motor deficit and the dopaminergic neuronal loss was no longer observed. These findings suggest that TRPM2 is involved in the PD-like pathology and that targeting TRPM2 may possibly represent a potential neuroprotective strategy for PD.
