N-Terminal 112 amino acid residues are not required for the sialyltransferase activity of Photobacterium damsela α2,6-sialyltransferase

, 2008
Photobacterium damsela α2,6-sialyltransferase was cloned as N- and C- His-tagged fusion proteins with different lengths (16–497 aa or 113–497 aa). Expression and activity assays indicated that the N-terminal 112 amino acid residues of the protein were ...

Sialyltransferase inhibition leads to inhibition of tumor cell interactions with E-selectin, VCAM1, and MADCAM1, and improves survival in a human multiple myeloma mouse model

Haematologica, 2020
Aberrant glycosylation resulting from altered expression of sialyltransferases, such as ST3 β-galactoside α2-3-sialyltransferase 6, plays an important role in disease progression in multiple myeloma (MM).

Genetic risk variants implicate impaired maintenance and repair of periodontal tissues as causal for periodontitis—A synthesis of recent findings

Periodontology 2000, EarlyView.
AbstractPeriodontitis is a complex inflammatory disease in which the host genome, in conjunction with extrinsic factors, determines susceptibility and progression. Genetic predisposition is the strongest risk factor in the first decades of life. As people age, chronic exposure to the periodontal microbiome puts a strain on the proper maintenance of ...

Chemoenzymatic Synthesis of Well‐Defined α(2,8)‐ and α(2,9)‐Linked Oligosialosides

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
Well‐defined α(2,8)‐ and α(2,9)‐linked oligosialic acids of different lengths can be prepared by employing recombinant bacterial polysialyltransferases in combination with chemically modified CMP‐Neu5Ac derivatives. After transfer, a sialoside is formed bearing an artificial entity, which blocks further glycosylation.

Translating gut microbiome research into therapies for type 1 diabetes

Experimental Physiology, EarlyView.
Abstract Type 1 diabetes (T1D) is characterised by the loss of functional pancreatic β‐cells, for which lifelong insulin therapy remains the standard of care. Given that the gut microbiome can influence host health and that shifts in gut microbial profiles have been observed in T1D, growing interest has emerged in the role of the gut microbiome in T1D,

Tissue-specific Expression of Sialyltransferases

Journal of Biological Chemistry, 1989
Three sialyltransferases which attach terminal sialic acids to glycoprotein sugar chains are shown to exhibit striking differential expression in seven tissues of the rat. Using cDNA probes for the Gal beta 1,4GlcNAc alpha-2,6-sialytransferase which forms a NeuAc alpha 2-6Gal beta 1-4GlcNAc sequence on N-linked sugar chains, three different sized mRNAs

Cell Surface Markers Identify Astrocyte Subpopulations in the Adult Hippocampus With a Heterogeneous Response to Aging

Glia, Volume 74, Issue 11, November 2026.
ATP1B2 and GLAST identify two astrocyte subpopulations in the hippocampus with distinct molecular signatures. Transcriptomic shifts during aging differ between both subpopulations. Aged ATP1B2+ astrocytes rewire their metabolism while double‐positive aged astrocytes display a reduced synaptogenic capability.

Sialic Acids in Health and Disease

Biologics
Vertebrate cell surfaces exhibit intricate arrangements of glycosaminoglycan polymers, which are primarily linked to lipids and proteins. Numerous soluble secreted proteins are also decorated with either individual sugar molecules or their polymers.

Glycoengineered Recombinant Alpha1‐Antitrypsin Results in Comparable In Vitro and In Vivo Activities to Human Plasma‐Derived Protein

Biotechnology and Bioengineering, Volume 123, Issue 10, Page 2605-2612, October 2026.
ABSTRACT Alpha‐1‐antitrypsin (A1AT) is a multifunctional, clinically important, high‐value therapeutic glycoprotein that can be used for the treatment of many diseases, such as A1AT deficiency, diabetes, graft‐versus‐host disease, cystic fibrosis, and various viral infections. Currently, the only U.S. food and drug administration‐approved treatment for
