1. Mice deficient for ST8SiaIV have impaired long-term spatial memory in two tasks that critically rely on the hippocampus.

2. Results demonstrate that the early development of calbindin-positive periglomerular interneurons depends on the presentation of polysialic acid on NCAM and requires the activity of both St8sia2 and St8sia4

3. NCAM-140 significantly promoted cell proliferation, motility and migration, while polysialylation of NCAM-140 catalyzed by STX, but not by PST, enhanced NCAM-mediated cell migration, but not cell proliferation or motility.

4. ST8SiaIV synthesized polySia selectively on a NRP2 glycoform that was characterized by the presence of sialylated core 1 and core 2 O-glycans.

5. Results indicate that the polySTs ST8SiaII and ST8SiaIV not only recognize an acidic patch in the FN1 domain of NCAM but also must contact sequences in the Ig5 domain for polysialylation of Ig5 N-glycans to occur.

6. the negative and positive effects of ST8SiaIV overexpression observed during peripheral nerve regeneration suggest that an optimized time- and differentiation-dependent control of expression in Schwann cells may further improve nerve regeneration

7. While both ST8SiaII and ST8SiaIV mRNA levels decrease around the time of eye opening in mouse visual cortex, only ST8SiaII mRNA level reduction is regulated by sensory experience

8. ST8Sia4 knockout mice display a decreased motivation in social interaction. This deficit can be partly explained by olfactory deficits and was associated with a clear decrease in PSA-NCAM expression in all brain regions analyzed.

9. This study demonistrated that mice lacking St8siaIV polysialyltransferase have an accelerated onset of remyelination after cuprizone-induced demyelination.

10. In summary, the data suggest that the polysialic acid-neural cell adhesion molecule system is a putative target for the modulation of

11. Focusing on the cerebral cortex, our results indicate that ST8SiaIV is solely responsible for PSA expression in mature interneurons and in most regions of cortical neuropil.

12. the coordinated action of ST8SiaII and ST8SiaIV is crucial to fine-tune the amount and structure of polySia on NCAM

13. The developmental changes in neural cell adhesion molecule polysialylation in wild-type, ST8SiaII-, and ST8SiaIV-deficient mice from postnatal days 1 to 21 and from adult mice, was monitored.

1. Different properties of polysialic acids synthesized by the polysialyltransferases ST8SIA2 and ST8SIA4 have been described.

2. our results demonstrate that miR-146a and miR-146b promote proliferation, migration and invasion of FTC via inhibition of ST8SIA4.

3. Data show that miR-181c was inversely correlated with the levels of ST8SIA4 expression in chronic myelocytic leukemia (CML) cell lines and samples.

4. This is the first report to demonstrate a role for a glycosyltransferase in human pluripotent stem cell lineage specification.

5. changes in the glycosylation patterns and sialylation levels may be useful markers of the progression of breast cancer, as well as miR-26a/26b may be widely involved in the regulation of sialylation machinery by targeting ST8SIA4.

6. The polybasic region of the polysialyltransferase ST8Sia-IV binds directly to NCAM.

7. Sequence Requirements for Neuropilin-2 Recognition by ST8SiaIV and Polysialylation of Its O-Glycans.

8. ST8SIA4 gene is involved in the development of multidrug resistance via PI3K/Akt pathway in chronic myeloid leukemia.

9. this study indicated that sialylation involved in the development of MDR of AML cells probably through ST3GAL5 or ST8SIA4 regulating the activity of PI3K/Akt signaling and the expression of P-gp and MRP1.

10. ST8SiaIV synthesized polySia selectively on a NRP2 glycoform that was characterized by the presence of sialylated core 1 and core 2 O-glycans.

11. The ST8SiaIV/PST polybasic region plays a critical role in substrate recognition.

12. polysialylated NCAM persistence, up-regulated polysialyltransferase-1 mRNA and previously uncovered defective myelin-associated glycoprotein may be early pathogenetic events in adult-onset autosomal-dominant leukodystrophy

13. SIAT8D has a role in neural development and sialic acid synthesis on NCAM

14. Pancreatitis risk was highest in individuals with abnormalities in pancreatic duct(CFTR) and acini (PST1) indicating that PST1 is a modifier gene for CFTR-related idiopathic chronic pancreatitis.

15. The upregulation of ST8SIA4 and the donwregulation of ST8SIA2 by valproic acid in HUVEC and tumor cell lines are reported.

16. polysialyltransferase ST8Sia IV/PST recognizes specific amino acids in the first fibronectin type III repeat of the neural cell adhesion molecule

17. PSA-NCAM and ST8Sia-II/IV Expression Is Increased in Pancreatic Carcinomas

18. Amino acid substitutions in conserved sequences are critical for the protein-specific polysialylation of NCAM.
