Chemotherapy Supports Cancer Cell Dissemination in a Melanoma Preclinical Model.

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
objectiveThe aim of the study was to determine how the chemotherapeutic alkylating agent dacarbazine, together with the application of the miR-204-5p mimic in vivo, affects the presence of disseminated melanoma cells in distant organs - the lungs and liver.
methodsThe study was carried out on B16 melanoma-bearing mice (n = 48). The animals were treated with dacarbazine (50 mg/kg) or dacarbazine combined with the microRNA miR-204-5p mimic (5 nM). Real-time PCR was used to evaluate the expression of miR-204-5p target genes following miR-204-5p mimic application. The presence of melanoma cells in distant organs was assessed by immunovisualization of the melanocyte marker PMEL using an immunohistochemical assay and by evaluating the expression of the melanocyte-specific protein tyrosinase via real-time PCR.
resultThe level of PMEL expression increased twofold in the lungs of mice treated with dacarbazine (p = 0.014) and 4.2-fold in the group of animals treated with a combination of dacarbazine and the miR-204-5p mimic (p = 0.001), as compared to the control group. However, tyrosinase expression was detected in the lungs of B16 melanoma-bearing mice treated with dacarbazine and the negative control only, due to the sporadic presence of melanoma cells in distant organs.
conclusionTaken together, dacarbazine and the miR-204-5p mimic favor the dissemination of B16 melanoma cells in the lungs, which may support further metastatic development. Although miR-204-5p has been described as a tumor-suppressive microRNA in melanoma, the application of a synthetic mimic to overexpress it in distant organs promoted tumor cell dissemination.
