An unusual glycoform of human salivary mucin MG2.

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
Since in a previous study we encountered a subject with an unusual split MG2 banding pattern, the aim of this study was to investigate the molecular basis of this observation. Submandibular/sublingual secretion was collected under resting and stimulated conditions and examined on Western blots probed with anti-MG2 antibodies or on gels stained with periodic acid-Schiff reagent. Genomic DNA was isolated and the N-, tandem repeat (TR), and C-terminal regions of MUC7 were amplified by PCR since MG2 is known to display a genetic polymorphism. Although the typical appearance of MG2 on blots and gels is a single 180 kDa band, salivary secretions from the subject exhibited doublet immunoreactive bands of approximately 180 and 125 kDa. Additionally, under resting conditions the 180 kDa band was predominant whereas upon stimulation the 125 kDa band became predominant. Genomic DNA analysis showed that MUC7 in the individual with split MG2 bands was not truncated and that the MUC7 genotype in this individual was (6/6) where both alleles encoded six TRs. The MG2 split banding pattern observed in this subject was not derived from proteolytic degradation of this salivary mucin in whole saliva or from genetic polymorphism. The expression of two isoforms of MG2 could in principle improve or reduce the activity of this key component of the oral host defense system.
