Humanin gene expression in subjects with Parkinson's disease.
Article in Molecular biology reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundBradykinesia, tremor, rigidity and postural instability are the hallmark of Parkinson's disease (PD). Non-motor symptoms including cognitive, behavioral, and neuropsychiatric changes, sensory and sleep disturbances that may precede the motor symptoms by years. The peculiar pathological features of PD are decreased dopaminergic neurons and dopamine levels in the substantia nigra pars compacta and pontine locus coeruleus. Humanin is produced by a small gene peptide, which is located in the mitochondria genome. Inflammation, oxidative stress, mitochondrial dysfunction and altered transcription have been recognized as causative factors of PD. This evidence has prompted many researchers to focus on studying the functions of DNA and mitochondria. The purpose of the present study was to evaluate Humanin mRNA levels in peripheral blood mononuclear cells (PBMCs) of PD subjects, compared with those in PBMCs of normal control (NC) subjects. METHODS AND
resultsA total of 220 participants, including 154 PD patients (57 females and 97 males; mean age 71.54 years, SD 7.8) and 66 CN (28 females and 38 males; mean age 70.54 years, SD 9.45) were enrolled for the qRT-PCR analysis. Increased Humanin mRNA levels were found in PD samples, compared to controls.
conclusionIn conclusion, the present data confirm the tendency of mitochondria to overexpress mRNA in PD, which could be a cellular attempt to reduce apoptotic damage in PD subjects. Humanin might be useful as a marker for a better diagnosis of PD, and we cannot exclude that in the future it might also play a role on prognosis and in the possible therapies for PD.
