Role of O-linked glycosylation modification on internalization and replication of avian leukosis virus subgroup J.
Article in Veterinary research, 2026. 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
Upon infection, viruses reprogram the host metabolic system to hijack metabolic resources for proliferation. Avian leukosis virus subgroup J (ALV-J), an avian oncogenic virus, poses significant challenges to the poultry industry. ALV-J infection upgrades monosaccharide N-acetylgalactosamine (GalNAc) and galactosyltransferase (core 1 β3-Gal-T) in DF-1 cells, both of which are crucial for O-linked glycosylation. Addition of GalNAc or overexpression of core 1 β3-Gal-T in DF-1 cells can promote ALV-J replication. ALV-J envelope protein (Env) undergoes complex post-translational modifications. Two O-linked glycosylation sites (T32 and T271) located in the head region of the ALV-J Env have been identified for the first time using liquid chromatography-mass spectrometry (LC-MS). The results of coimmunoprecipitation and flow cytometry indicate that mutations in T32 or T271 diminish ALV-J infection by affecting viral internalization, rather than attachment. The viral internalization efficiency was partially restored under a low pH environment. Incorporation of T32A and T271A into ALV-J led to significantly reduced replication capacity in vivo and viral shedding of the recombinant virus. These findings are valuable for our understanding of the roles of glycans in the ALV-J infection cycle, as well as for providing potential anti-ALV-J strategies.
