From structural to functional glycomics: core substitutions as molecular switches for shape and lectin affinity of N-glycans [PDF]

, 2009
Glycan epitopes of cellular glycoconjugates act as versatile biochemical signals (sugar coding). Here, we test the hypothesis that the common N-glycan modifications by core fucosylation and introduction of the bisecting N-acetylglucosamine moiety have ...

Surface Avidity of Anionic Polypeptide Coatings on Layer‐by‐Layer Nanoparticles Target Cancer‐Associated Amino Acid Transporters

Angewandte Chemie, EarlyView.
Electrostatically layered nanoparticles (NPs) coated with anionic polypeptides selectively target cancer cells by engaging amino acid transporters. Poly(L‐glutamate) (PLE) coatings cluster the glutamine transporter SLC1A5, prolonging NP surface retention, while poly(L‐aspartate) (PLD) coatings also bind SLC1A3, potentially promoting faster ...

Prognostic significance of endogenous adhesion/growth-regulatory lectins in lung cancer [PDF]

, 2005
Objective: To determine the expression of endogenous adhesion/growth-regulatory lectins and their binding sites using labeled tissue lectins as well as the binding profile of hyaluronic acid as an approach to define new prognostic markers.

Galectin-1(L11A) Predicted from a Computed Galectin-1 Farnesyl-Binding Pocket Selectively Inhibits Ras-GTP [PDF]

Cancer Research, 2004
Abstract Ras biological activity necessitates membrane anchorage that depends on the Ras farnesyl moiety and is strengthened by Ras/galectin-1 interactions. We identified a hydrophobic pocket in galectin-1, analogous to the Cdc42 geranylgeranyl-binding cavity in RhoGDI, possessing homologous isoprenoid-binding residues, including the ...

Synthetic Nanobiology Actuated Lipometabolic Cell Factory for Autologous Tumor Immunotherapy

Advanced Functional Materials, EarlyView.
FA plays a crucial role in the interaction between tumor cells and the tumor microenvironment, especially for the immune response. A biocatalytic immunoenhancement strategy is developed to boost antitumor immunity by FA metabolic orientation to ceramide. Through the design of this delicate catalytic immunoenhancement strategy, the synthetic nanobiology

Galectin-1 Regulates RNA Expression and Alternative Splicing of Angiogenic Genes in HUVECs

Frontiers in Bioscience-Landmark, 2023
Background: Angiogenesis is essential for tissue development, and therefore its dysregulation can cause various diseases, including cerebrovascular disease. Galectin-1, encoded by the lectin galactoside-binding soluble-1 gene (LGALS1), has critical roles

Duodenal intraepithelial lymphocytes of children with cow milk allergy preferentially bind the glycan-binding protein galectin-3 [PDF]

, 2009
A breakdown in intestinal homeostasis results in inflammatory bowel diseases including coeliac disease and allergy. Galectins, evolutionarily conserved beta-galactoside-binding proteins, can modulate immune-epithelial cell interactions by influencing ...

Galectin-1 receptors in different cell types

Journal of Biomedical Science, 2005
Galectins are a family of animal lectins defined by two properties: shared amino acid sequences in their carbohydrate-recognizing domain, and beta-galactoside affinity. A wide variety of biological phenomena are related to galectins, i.e., development, differentiation, morphogenesis, tumor metastasis, apoptosis, RNA splicing, and immunoregulatory ...

Engineered Mesenchymal Stem Cell–NK Cell Complexes for Spatially Targeted and Functionally Revitalized Cancer Immunotherapy

Advanced Science, EarlyView.
IL‐15‐engineered stem cell–NK cell complexes, assembled via bioorthogonal chemistry, enable effective lung cancer immunotherapy. Abstract Natural killer (NK) cells represent a powerful immunotherapeutic strategy due to their intrinsic cytotoxicity and ability to target tumor cells independently of antigen presentation.

Galectin-1-Induced Autophagy Facilitates Cisplatin Resistance of Hepatocellular Carcinoma. [PDF]

PLoS ONE, 2016
Hepatocellular carcinoma (HCC) is one of the most common cancers in Taiwan. Although chemotherapy is the primary treatment for HCC patients, drug resistance often leads to clinical failure.
