BMP-2 regulates the expression of myosin Va via smad in melan-a melanocyte.
Article in Archives of dermatological research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Myosin Va (Myo Va) is one of three protein complexes involved in melanosome transport. In this study, we identified BMP-2 as an up-regulator of Myo Va expression using 2-methyl-naphtho[1,2,3-de]quinolin-8-one (MNQO). Our results showed that MNQO reduced the mRNA and protein expression of Myo Va and BMP-2 in melanocytes. Knockdown of BMP-2 by siRNA also affected Myo Va mRNA and protein expression, confirming that MNQO regulates Myo Va through BMP-2. Furthermore, phosphorylation of Smad1/5/8 by BMP2 treatment confirmed that the BMP-2/Smad signaling pathway regulates Myo Va expression in Melan-a melanocytes. Smad-binding elements were found in the Myo Va promoter and phosphorylated Smad1/5/8 bind directly to the Myo Va promoter to activate Myo Va transcription and BMP-2 enhances this binding. These findings provide insight into a new role for BMP-2 in Melan-a melanocytes and a mechanism of regulation of Myo Va expression that may be beneficial in the treatment of albinism or hyperpigmentation disorders.
