Plasmid DNA vaccine coding eight repeats of gonadotrophin-releasing hormone induced atrophy of prostate in male mice.

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
backgroundProstate hyperplasia and neoplasia are major illness of men and elderly dogs. Treatment of prostate cancer requires androgen deprivation surgery or therapy to prevent metastases and alleviate pain. Recently, six DNA vaccines have entered clinical trials against prostate cancer in humans with limited success. There is a need for new therapies that delay the establishment of malignancy and prolong survival. MATERIALS AND
methodsA plasmid DNA vaccine coding for eight gonadotrophin-releasing hormone (GnRH-I) interspersed in eight T-helper epitopes was used. Sexually mature male mice were immunized with the vaccine in hemagglutinating virus of Japanese envelope vector and boosted in nonionized surfactant vesicles in study weeks 0, 3, 6, 9, and 12. Plasma anti-GnRH-I antibody response, serum testosterone concentration, and effect on prostate were evaluated.
resultsResults of an indirect enzyme linked immunosorbent assay (ELISA) showed anti-GnRH-I antibody response (OD value) detected in the study week 3 (0.613 ± 0.179) with a highest response in the week 12 (1.205 ± 0.219). Serum testosterone concentration (ng/ml) in vaccinated mice was significantly reduced (
conclusionsImmunization strategy designed with the plasmid DNA vaccine in hemagglutinating virus of Japanese envelope and nonionized surfactant vesicles can be the genetic immunization platform. This vaccine bears potentials in terms of reducing serum testosterone concentration and induction of atrophy of prostate. Targeted ablation of native GnRH-I by genetic immunization could offer leverage to vaccinologists, seeking therapeutic target to control and prevent malignancy of prostate.
