BACKGROUND: Increasing rice demand is one of the consequences of the steadily improving socio-economic status of the African countries. New Rice for Africa (NERICA), which are interspecific hybrids between Asian and African rice varieties, are one of successful breeding products utilizing biodiversity across the two different rice crop species. Upland NERICA varieties (NU) exhibit agronomic traits of value for the harsh eco-geography, including shorter duration, higher yield and stress tolerance, compared to local African varieties...

Umbilical cord blood (UCB)-derived hematopoietic stem cells (HSCs) are considered because of their self-renewing, differentiating, proliferating, and readily available properties. Moreover, HSCs' homing to the hematopoietic microenvironment is an important step in their transplantation process. But low content of progenitor cells in one unit of UCB and defect in the bone marrow (BM) homing limit their applications. Hence, we decided to correct this deficiency with ex vivo incubation of CD133+ cells using fucosyltransferase VI and GDP-fucose...

Flooding negatively affects the growth of soybean, whereas the plant-derived smoke enhances seedling growth of crops. To clarify the mechanism underlying the recovery from flooding stress, proteomic analysis was performed based on morphological results. Growth of soybean seedlings was inhibited under flooding stress, but it recovered after water removal following treatment with plant-derived smoke. Sucrose/starch metabolism and glycolysis were suppressed in smoke-treated flooded soybean compared to flooded soybean...

Dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) is an important C-type lectin and plays a critical role in the recognition of pathogens and self-antigens. It has recently been shown that DC-SIGN directly interacts with acute T lymphoblastic leukemia cells. However, the mechanism regulating DC-SIGN-dependent DC association as well as related functions is still elusive. Here we showed that DC-SIGN preferentially bound to a set of malignant T lymphocytes, including Jurkat, CCRF-HSB2 and CCRF-CEM...

N -linked glycosylation is one of the key post-translational modifications. α1,3-Fucosyltransferase (OsFucT) is responsible for transferring α1,3-linked fucose residues to the glycoprotein N -glycan in plants. We characterized an Osfuct mutant that displayed pleiotropic developmental defects, such as impaired anther and pollen development, diminished growth, shorter plant height, fewer tillers, and shorter panicle length and internodes under field conditions. In addition, the anthers were curved, the pollen grains were shriveled, and pollen viability and pollen number per anther decreased dramatically in the mutant...

Transient recombinant protein production is a promising alternative to stable transgenic systems, particularly for emergency situations in which rapid production of novel therapeutics is needed. In plants, Agrobacterium tumefaciens can be used as a gene delivery vector for transient expression. A potential barrier for plant-based production of human therapeutics is that different glycosylation patterns are found on plant and mammalian proteins. Since glycosylation can affect the efficacy, safety and stability of a therapeutic protein, methods to control glycan structures and distributions in plant-based systems would be beneficial...

In humans, six α(1,3)-fucosyltransferases (α(1,3)-FTs: FT3/FT4/FT5/FT6/FT7/FT9) reportedly fucosylate terminal lactosaminyl glycans yielding Lewis X (LeX ; CD15) and/or sialyl Lewis X (sLeX ; CD15s), structures that play key functions in cell migration, development, and immunity. Prior studies analyzing α(1,3)-FT-specificities utilized either purified and/or recombinant enzymes to modify synthetic substrates under non-physiological reaction conditions or molecular biology approaches wherein α(1,3)-FTs were expressed in mammalian cell lines, notably excluding investigations using primary human cells...

Dowling-Degos disease (DD) (OMIM: 179850, 615327, 615674, 615696) is a rare autosomal-dominant genetic disorder belonging to the spectrum of reticulated pigmented dermatitis(1). Galli-Galli disease is considered as being a variant of DD, harboring all clinical, histological and genetics features of DD in association with acantholysis (2). In 2006, exome sequencing revealed loss-of-function mutations in KRT5 (cytokeratin 5) (p.Ile140fsAsnfs*39, p.Ser5*) in 8 of 10 DD cases (3). Since then, mutations in POGLUT1, encoding O-glucosylosyltransferase 1 enzyme, were reported in Galli-Galli cases (4)...

Heritability analysis of the microbiota has demonstrated the importance of host genotype in defining the human microbiota. The alpha (1,2)-fucosyltransferase 2 encoded by FUT2 is involved in the formation of the H antigen and the SNP, rs601338 is associated with ABO histo-blood group antigen secretion in the intestinal mucosa. Previous studies have provided non replicated results for the association of this polymorphism with the composition and inferred function of intestinal microbiota. We aimed to assess this relationship in a large cohort of 1,190 healthy individuals...

Aberrant glycosylation of tumor cells is recognized as a universal hallmark of cancer pathogenesis. Overexpression of fucosylated epitopes, such as type I (H1, Lewisa , Lewisb , and sialyl Lewisa ) and type II (H2, Lewisx , Lewisy , and sialyl Lewisx ) Lewis antigens, frequently occurs on the cancer cell surface and is mainly attributed to upregulated expression of pertinent fucosyltransferases (FUTs). Nevertheless, the impact of fucose-containing moieties on tumor cell biology is not fully elucidated yet. Here, we review the relevance of tumor-overexpressed FUTs and their respective synthesized Lewis determinants in critical aspects associated with cancer progression, such as increased cell survival and proliferation, tissue invasion and metastasis, endothelial to mesenchymal transition, endothelial and immune cell interaction, angiogenesis, multidrug resistance, and cancer stemness...

Tissue stroma is known to be important in regulating Hp-mediated inflammation, but its interaction with Hp and dendritic cells (DCs) remains to be determined. To this end, the potential crosstalk between H. pylori (Hp) infected gastric stromal cells (Hp-GSCs) and DCs was investigated. Primary GSCs from cancerous and adjacent normal tissues were generated from gastric cancer patients, and monocyte-derived DCs were obtained from healthy individuals. Levels of cytokines and prostaglandin E2 (PGE2 ) were measured by ELISA, and C-type lectin expression in GSCs was assessed by flow cytometry and immunohistochemistry...

T cells mediating influenza viral control are instructed in lymphoid and nonlymphoid tissues to differentiate into memory T cells that confer protective immunity. The mechanisms by which influenza virus-specific memory CD4+ T cells arise have been attributed to changes in transcription factors, cytokines and cytokine receptors, and metabolic programming. The molecules involved in these biosynthetic pathways, including proteins and lipids, are modified to varying degrees of glycosylation, fucosylation, sialation, and sulfation, which can alter their function...

During pollen-pistil interactions in angiosperms, the male gametophyte (pollen) germinates to produce a pollen tube. To fertilize ovules located within the female pistil, the pollen tube must physically penetrate specialized tissues. Whereas the process of pollen tube penetration through the pistil has been anatomically well described, the genetic regulation remains poorly understood. In this study, we identify a novel Arabidopsis ( Arabidopsis thaliana ) gene, O-FUCOSYLTRANSFERASE1 ( AtOFT1 ), which plays a key role in pollen tube penetration through the stigma-style interface...

Protein O-fucosyltransferase-1 (POFUT1) adds O-fucose monosaccharides to epidermal growth factor-like (EGF) repeats found on approximately 100 mammalian proteins, including Notch receptors. Haploinsufficiency of POFUT1 has been linked to adult-onset Dowling Degos Disease (DDD) with hyperpigmentation defects. Homozygous deletion of mouse Pofut1 results in embryonic lethality with severe Notch-like phenotypes including defects in somitogenesis, cardiogenesis, vasculogenesis, and neurogenesis, but the extent to which POFUT1 is required for normal human development is not yet understood...

CD4+ T cell activation promotes the pathogenic process of systemic lupus erythematosus (SLE). T cell receptor (TCR) complex are highly core fucosylated glycoproteins, which play important roles in T cell activation. In this study, we found that the core fucosylation of CD4+ T cells was significantly increased in SLE patients. Loss of core fucosyltransferase (Fut8), the sole enzyme for catalyzing the core fucosylation of N-glycan, significantly reduced CD4+ T cell activation and ameliorated the experimental autoimmune encephalomyelitis-induced syndrome in Fut8-/- mice...

Selectin-ligand interactions are important for leukocyte homing and functionality. The roles of selectin-ligand interactions in modulating immunity to intracellular infections are not completely understood. Mice lacking the expression of fucosyltransferase-IV and -VII (Fucosyltransferase-IV and -VII double knockout, FtDKO) exhibit deficient functionality of selectin-ligand interactions. We addressed the kinetics of infection and immunity to Listeria monocytogenes (LM), an intracellular pathogen, in FtDKO mice...

Glycosylation is recognized as one of the most common modifications on proteins. Recent studies have shown that aberrant expression of α (1,6) fucosyltransferase (FUT8), which catalyzes the transfer of fucose from GDP-fucose to core-GlcNAc of the N-linked glycoproteins, modulates cellular behavior that could lead to the development of aggressive prostate cancer. While the relationship between the abnormal expression of FUT8 and glycoprotein fucosylation in different prostate cancer cells has been demonstrated, there is no evidence that shows dysregulated fucosylation might be involved in prostate cancer progression from androgen-dependent to castration-resistant prostate cancer...
