Abstract
Gastric cancer with peritoneal dissemination is difficult to treat surgically, and frequently recurs and metastasizes. Currently, there is no effective treatment for this disease, and there is an urgent need to elucidate the molecular mechanisms underlying peritoneal dissemination and metastasis. Our previous study demonstrated that galectin-4 participates in the peritoneal dissemination of poorly differentiated gastric cancer cells. In this study, the glycan profiles of cell surface proteins and glycosphingolipids (GSLs) of the original (wild), galectin-4 knockout (KO), and rescue cells were investigated to understand the precise mechanisms involved in the galectin-4-mediated regulation of associated molecules, especially with respect to glycosylation. Glycan analysis of the NUGC4 wild type and galectin-4 KO clones with and without peritoneal metastasis revealed a marked structural change in the glycans of neutral GSLs, but not in N-glycan. Furthermore, mass spectrometry (MS) combined with glycosidase digestion revealed that this structural change was due to the presence of the lacto-type (β1-3Galactosyl) glycan of GSL, in addition to the neolacto-type (β1-4Galactosyl) glycan of GSL. Our results demonstrate that galectin-4 is an important regulator of glycosylation in cancer cells and galectin-4 expression affects the glycan profile of GSLs in malignant cancer cells with a high potential for peritoneal dissemination.

Abstract
Galectins are carbohydrate-binding lectins that modulate the proliferation, apoptosis, adhesion, or migration of cells by cross-linking glycans on cell membranes or extracellular matrix components. Galectin-4 (Gal-4) is a tandem-repeat-type galectin expressed mainly in the epithelial cells of the gastrointestinal tract. It consists of an N- and a C-terminal carbohydrate-binding domain (CRD), each with distinct binding affinities, interconnected with a peptide linker. Compared to other more abundant galectins, the knowledge of the pathophysiology of Gal-4 is sparse. Its altered expression in tumor tissue is associated with, for example, colon, colorectal, and liver cancers, and it increases in tumor progression, and metastasis. There is also very limited information on the preferences of Gal-4 for its carbohydrate ligands, particularly with respect to Gal-4 subunits. Similarly, there is virtually no information on the interaction of Gal-4 with multivalent ligands. This work shows the expression and purification of Gal-4 and its subunits and presents a structure-affinity relationship study with a library of oligosaccharide ligands. Furthermore, the influence of multivalency is demonstrated in the interaction with a model lactosyl-decorated synthetic glycoconjugate. The present data may be used in biomedical research for the design of efficient ligands of Gal-4 with diagnostic or therapeutic potential.

Abstract
BACKGROUND Galectins are β-galactoside binding proteins. Galectin-4 has shown an effect on cancer progression/metastasis, especially in cancers of the digestive system. This can be attributed to altered glycosylation pattern of cell membrane molecules, which is a characteristic attribute of oncogenesis. The aim of this paper is to systematically review galectin-4 in different cancers and its role in disease progression. METHODS The study was designed on the basis of Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. PubMed, Scopus, Web of Science, and Science Direct were used to search relevant literature with keywords "galectin-4 AND cancer", "galectin-4", "LGALS4", and "LGALS4 AND cancer". Inclusion criteria for study selection were availability of full-text articles, articles in English language and articles relevant to current topic, i.e., galectin-4 and cancer. Exclusion criteria were studies that investigated other disease conditions, interventions unrelated to cancer or galectin-4 and bias outcome. RESULTS A total of 73 articles were retrieved after removing duplication from databases, out of which 40 studies were included in the review that followed the inclusion criteria, including low to moderate bias. These included 23 studies in digestive system, 5 in reproductive system, 4 in respiratory system, and 2 in brain and urothelial cancers. CONCLUSIONS A differential expression of galectin-4 was observed in different cancer stages/ and types. Furthermore, galectin-4 was found to modulate disease progression. A meta-analysis and comprehensive mechanistic studies, pertaining to different aspects of galectin-4 biology, could give statistically driven correlations, elucidating multifaceted role of galectin-4 in cancer.

Abstract
Galectin-4, a member of the galectin family of animal glycan-binding proteins (GBPs), is specifically expressed in gastrointestinal epithelial cells and is known to be able to bind microbes. However, its function in host-gut microbe interactions remains unknown. Here, we show that intracellular galectin-4 in intestinal epithelial cells (IECs) coats cytosolic Salmonella enterica serovar Worthington and induces the formation of bacterial chains and aggregates. Galectin-4 enchains bacteria during their growth by binding to the O-antigen of lipopolysaccharides. Furthermore, the binding of galectin-4 to bacterial surfaces restricts intracellular bacterial motility. Galectin-4 enhances caspase-1 activation and mature IL-18 production in infected IECs especially when autophagy is inhibited. Finally, orally administered S. enterica serovar Worthington, which is recognized by human galectin-4 but not mouse galectin-4, translocated from the intestines to mesenteric lymph nodes less effectively in human galectin-4-transgenic mice than in littermate controls. Our results suggest that galectin-4 plays an important role in host-gut microbe interactions and prevents the dissemination of pathogens. The results of the study revealed a novel mechanism of host-microbe interactions that involves the direct binding of cytosolic lectins to glycans on intracellular microbes.

Abstract
Galectin-4 (Gal-4) is a β-galactoside-binding protein belonging to the galectin family. Although Gal-4 is known to be involved in several physiologic processes of the gastrointestinal tract, its immunomodulatory roles remain unclear. In this study, we investigated whether Gal-4 influences the function of M1 and M2 macrophages. Gal-4 treatment drove more robust changes in the gene expression of M2 macrophages compared to M1 macrophages. Antiviral immune response-related genes were significantly upregulated in Gal-4-treated M2 macrophages. Gal-4 significantly enhanced the immunostimulatory activity of M2 macrophages upon Toll-like receptor 7 stimulation or infection with lymphocytic choriomeningitis virus (LCMV). Moreover, the antibody production against LCMV infection and the antiviral CD4+ T-cell responses, but not the antiviral CD8+ T-cell responses, were greatly increased by Gal-4-treated M2 macrophages in vivo. The present results indicate that Gal-4 enhances the ability of M2 macrophages to promote antiviral CD4+ T-cell responses. Thus, Gal-4 could be used to boost antiviral immune responses.

Abstract
The tandem-repeat Galectin-4 (Gal-4) contains two different domains covalently linked through a short flexible peptide. Both domains have been shown to bind preferentially to A and B histo blood group antigens with different affinities, although the binding details are not yet available. The biological relevance of these associations is unknown, although it could be related to its attributed role in pathogen recognition. The presentation of A and B histo blood group antigens in terms of peripheral core structures differs among tissues and from that of the antigen-mimicking structures produced by pathogens. Herein, the binding of the N-terminal domain of Gal-4 toward a group of differently presented A and B oligosaccharide antigens in solution has been studied through a combination of NMR, isothermal titration calorimetry (ITC), and molecular modeling. The data presented in this paper allow the identification of the specific effects that subtle chemical modifications within this antigenic family have in the binding to the N-terminal domain of Gal-4 in terms of affinity and intermolecular interactions, providing a structural-based rationale for the observed trend in the binding preferences.

Abstract
Galectins are soluble carbohydrate binding proteins that can bind β-galactose-containing glycoconjugates by means of a conserved carbohydrate recognition domain (CRD). In mammalian systems, galectins have been shown to mediate very important roles in innate and adaptive immunity as well as facilitating host-pathogen relationships. Many of these studies have relied on purified recombinant galectins to uncover key features of galectin biology. A major limitation to this approach is that certain recombinant galectins purified using standard protocols are easily susceptible to loss of glycan-binding activity. As a result, biochemical studies that employ recombinant galectins can be misleading if the overall activity of a galectin remains unknown in a given assay condition. This article examines fundamental considerations when purifying galectins by lactosyl-sepharose and nickel-NTA affinity chromatography using human galectin-4N and -7 as examples, respectively. As other approaches are also commonly applied to galectin purification, we also discuss alternative strategies to galectin purification, using human galectin-1 and -9 as examples. © 2021 Wiley Periodicals LLC.

Abstract
Emerging evidence on efficient tumor growth regulation by endogenous lectins directs interest to determine on a proof-of-principle level the range of information on alterations provided by full-scale analysis using phosphoproteomics. In our pilot study, we tested galectin-4 (gal-4) that is a growth inhibitor for colon cancer cells (CRC), here working with the LS 180 line. In order to cover monitoring of short- and long-term effects stable isotope labeling by amino acids in cell culture-based quantitative phosphoproteomic analyses were conducted on LS 180 cell preparations collected 1 and 72 h after adding gal-4 to the culture medium. After short-term treatment, 981 phosphosites, all of them S/T based, were detected by phosphoproteomics. Changes higher than 1.5-fold were seen for eight sites in seven proteins. Most affected were the BET1 homolog (BET1), whose level of phosphorylation at S50 was about threefold reduced, and centromere protein F (CENPF), extent of phosphorylation at S3119 doubling in gal-4-treated cells. Phosphoproteome analysis after 72 h of treatment revealed marked changes at 33 S/T-based phosphosites from 29 proteins. Prominent increase of phosphorylation was observed for cofilin-1 at position S3. Extent of phosphorylation of the glutamine transporter SLC1A5 at position S503 was decreased by a factor of 3. Altered phosphorylation of BET1, CENPF, and cofilin-1 as well as a significant effect of gal-4 treatment on glutamine uptake by cells were substantiated by independent methods in the Vaco 432, Colo 205, CX 1, and HCT 116 cell lines. With the example of gal-4 which functions as a tumor suppressor in CRC cells, we were able to prove that cell surface binding of the lectin not only markedly influences the cell proteome, but also has a bearing on malignancy-associated intracellular protein phosphorylation. These results underscore the potential of this approach to give further work on elucidating the details of signaling underlying galectin-triggered growth inhibition a clear direction. © 2018 IUBMB Life, 71(3):364-375, 2019.

Abstract
Disseminated castration-resistant prostate cancer (CRPC) is a common disease in men that is characterized by limited survival and resistance to androgen-deprivation therapy. The increase in human epidermal growth factor receptor 2 (HER2) signaling contributes to androgen receptor activity in a subset of patients with CRPC; however, enigmatically, HER2-targeted therapies have demonstrated a lack of efficacy in patients with CRPC. Aberrant glycosylation is a hallmark of cancer and involves key processes that support cancer progression. Using transcriptomic analysis of prostate cancer data sets, histopathologic examination of clinical specimens, and in vivo experiments of xenograft models, we reveal in this study a coordinated increase in glycan-binding protein, galectin-4, specific glycosyltransferases of core 1 synthase, glycoprotein- N-acetylgalactosamine 3-β-galactosyltransferase 1 (C1GALT1) and ST3 beta-galactoside α-2,3-sialyltransferase 1 (ST3GAL1), and resulting mucin-type O-glycans during the progression of CRPC. Furthermore, galectin-4 engaged with C1GALT1-dependent O-glycans to promote castration resistance and metastasis by activating receptor tyrosine kinase signaling and cancer cell stemness properties mediated by SRY-box 9 (SOX9). This galectin-glycan interaction up-regulated the MYC-dependent expression of C1GALT1 and ST3GAL1, which altered cellular mucin-type O-glycosylation to allow for galectin-4 binding. In clinical prostate cancer, high-level expression of C1GALT1 and galectin-4 together predict poor overall survival compared with low-level expression of C1GALT1 and galectin-4. In summary, MYC regulates abnormal O-glycosylation, thus priming cells for binding to galectin-4 and downstream signaling, which promotes castration resistance and metastasis.-Tzeng, S.-F., Tsai, C.-H., Chao, T.-K., Chou, Y.-C., Yang, Y.-C., Tsai, M.-H., Cha, T.-L., Hsiao, P.-W.

Abstract
Galectine-4 (gal-4), encoded by the LGALS4 gene, was recently shown to exhibit a tumor suppressive effect in colorectal carcinoma and pancreatic adenocarcinoma, although how the expression of this gene is regulated remains unknown. No reports describe the significance of gal-4 in the malignant potential of urothelial tumors. Thus, we analyzed LGALS4 methylation and gene expression and their clinical relevance and biological function in urothelial carcinoma (UC). LGALS4 methylation was initially identified as a progression biomarker for UC patients through genome-wide DNA methylation profiling of 16 tumor samples. Bisulfite sequencing PCR and immunohistochemistry were performed to validate the promoter methylation and expression of LGALS4. We used quantitative methylation-specific PCR to determine the methylation levels of LGALS4 normalized to ACTB in the tumor samples of 79 UC patients and compared the levels between patients with different clinicopathological characteristics. The association with survival probability was analyzed with the Kaplan-Meier method and Cox regression analysis. The ectopic expression of gal-4 in cancer cell lines was used to address its biological function in UC in vitro. The promoter hypermethylation of LGALS4 (>2.51, log10 scale) revealed a positive correlation with high levels of both histological grade and tumor T category and with lymph node metastasis (all P≤0.001). In addition, LGALS4 hypermethylation was an independent predictor of inferior survival in UC patients (P<0.05). The ectopic expression studies demonstrated that gal-4 suppressed urothelial cancer cell growth, migration, and invasion. Thus, LGALS4 may function as a tumor suppressor gene in UC progression. Our findings provide evidence that methylation-mediated LGALS4 gene repression may be involved in urothelial tumor progression.

Abstract
One long-term complication of chronic intestinal inflammation is the development of colorectal cancer. However, the mechanisms linking inflammation to the colorectal tumorigenesis are poorly defined. Previously, we have demonstrated that galectin-4 is predominantly expressed in the luminal epithelia of the gastrointestinal tract, and its loss of expression plays a key role in the colorectal tumorigenesis. However, the mechanism by which galectin-4 regulates inflammation-induced tumorigenesis is unclear. Here, we show that galectin-4 secreted by the colorectal cancer cell lines was bound to the cell surface. Neutralization of surface-bound galectin-4 with anti-galectin-4 antibody resulted in increased cell proliferation with concomitant secretion of several chemokines into the extracellular medium. Neutralization of the surface-bound galectin-4 also resulted in the up-regulation of transcription of 29 genes, several of which are components of multiple inflammation signaling pathways. In an alternate experiment, binding of recombinant galectin-4 protein to cell surface of the galectin-4-negative colorectal cancer cells resulted in increased p27, and decreased cyclin D1 and c-Myc levels, leading to cell cycle arrest and apoptosis. Together, these data demonstrated that surface-bound galectin-4 is a dual function protein-down-regulating cell proliferation and chemokine secretion in galectin-4-expressing colorectal cancer cells on one hand and inducing apoptosis in galectin-4-negative colorectal cancer cells on the other hand.

Abstract
Galectin-4, a tandem repeat member of the β-galactoside-binding proteins, possesses two carbohydrate-recognition domains (CRD) in a single peptide chain. This lectin is mostly expressed in epithelial cells of the intestinal tract and secreted to the extracellular. The two domains have 40% similarity in amino acid sequence, but distinctly binding to various ligands. Just because the two domains bind to different ligands simultaneously, galectin-4 can be a crosslinker and crucial regulator in a large number of biological processes. Recent evidence shows that galectin-4 plays an important role in lipid raft stabilization, protein apical trafficking, cell adhesion, wound healing, intestinal inflammation, tumor progression, etc. This article reviews the physiological and pathological features of galectin-4 and its important role in such processes.

Abstract
Breast cancer is the most frequent cancer threatening the lives of women between the ages of 30 and 64. The cancer antigen 15-3 assay (CA15-3) has been widely used for the detection of breast cancer recurrence; however, its sensitivity and specificity are inadequate. We previously found that the breast cancer cell line YMBS secretes mucin 1 possessing 3'-sulfated core1 (3Score1-MUC1) into the medium. Therefore, we here evaluated whether 3Score1-MUC1 is secreted into the blood streams of breast cancer patients, and whether it can serve as an improved breast cancer marker. We developed a lectin-sandwich immunoassay, called Gal4/MUC1, using a 3'-sulfated core1-specific galectin-4 and a MUC1 monoclonal antibody. Using the Gal4/MUC1 assay method, we found that 3Score1-MUC1 was profoundly expressed in the blood streams of patients with recurrent and/or metastatic breast cancer. The positive ratio of the Gal4/MUC1 assay was higher than that of the CA15-3 assay in both primary (n = 240) and relapsed (n = 43) patients, especially in the latter of which the positive ratio of Gal4/MUC1 was 86%. whereas that of CA15-3 was 47%. Furthermore, serum Gal4/MUC1 levels could more sensitively reflect the recurrence of primary breast cancer patients after surgery. Therefore, the Gal4/MUC1 assay should be an excellent alternative to the CA15-3 tumor marker for tracking the recurrence and metastasis of breast cancer.

Abstract
Galectin-4 is a multifunctional lectin found at both intracellular and extracellular sites. It could serve as a tumor suppressor intracellularly and promote tumor metastases extracellularly during colorectal cancer development. However, galectin-4 expression and its prognostic value for patients with hepatocellular carcinoma (HCC) have not been well investigated. Here we report that galectin-4 was significantly downregulated in early recurrent/metastatic HCC patients, when compared to non-recurrent/metastatic HCC patients. Low expression of gelectin-4 was well associated with larger tumor size, microvascular invasion, malignant differentiation, more advanced TNM stage, and poor prognosis. Cancer cell migration and invasion could be significantly reduced through overexpression of galectin-4, but upregulated by knocking down of galectin-4 in vitro. Moreover, the serum galectin-4 level could be significantly elevated solely by hepatitis B virus infection. Combined with clinicopathological features, the higher serologic level of galectin-4 was well associated with more aggressive characteristics of HCC. Taken together, galectin-4 expression closely associates with HCC progression and might have potential use as a prognostic biomarker for HCC patients.

Abstract
Galectin-4 (Gal-4) has been recently identified as a pivotal factor in the migratory capabilities of a set of defined pancreatic ductal adenocarcinoma (PDAC) cell lines using zebrafish as a model system. Here we evaluated the expression of Gal-4 in PDAC tissues selected according to their lymph node metastatic status (N0 vs. N1), and investigated the therapeutic potential of targeting the cross-link with the Wnt signaling pathway in primary PDAC cells. Analysis of Gal-4 expression in PDACs showed high expression of Gal-4 in 80% of patients without lymph node metastasis, whereas 70% of patients with lymph node metastases had low Gal-4 expression. Accordingly, in primary PDAC cells high Gal-4 expression was negatively associated with migratory and invasive ability in vitro and in vivo. Knockdown of Gal-4 in primary PDAC cells with high Gal-4 expression resulted in significant increase of invasion (40%) and migration (50%, P<0.05), whereas enforced expression of Gal-4 in primary cells with low Gal-4 expression reduced the migratory and invasive behavior compared to the control cells. Gal-4 markedly reduces β-catenin levels in the cell, counteracting the function of Wnt signaling, as was assessed by down-regulation of survivin and cyclin D1. Furthermore, Gal-4 sensitizes PDAC cells to the Wnt inhibitor ICG-001, which interferes with the interaction between CREB binding protein (CBP) and β-catenin. Collectively, our data suggest that Gal-4 lowers the levels of cytoplasmic β-catenin, which may lead to lowered availability of nuclear β-catenin, and consequently diminished levels of nuclear CBP-β-catenin complex and reduced activation of the Wnt target genes. Our findings provide novel insights into the role of Gal-4 in PDAC migration and invasion, and support the analysis of Gal-4 for rational targeting of Wnt/β-catenin signaling in the treatment of PDAC.
