[PMID: 37176079 PMCID: PMC10179438 DOI: 10.3390/ijms24098373] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/02/2023] [Accepted: 05/05/2023] [Indexed: 05/15/2023] Open
Abstract
Lactoferrin (Lf) is a multifunctional protein from the transferrin family. Of particular interest is the ability of Lf to affect a wide range of neuronal processes by modulating the expression of genes involved in long-term neuroplasticity. The expression of the immediate early gene c-fos that is rapidly activated in response to external influences, and its product, transcription factor c-Fos, is widely used as a marker of long-term neuronal plasticity. The present study aims to examine the effect of human Lf on the induction of transcription factor c-Fos in the primary mouse neuronal cultures after stimulation and to determine the cellular localization of human Lf and its colocalization with induced c-Fos protein. Primary dissociated cultures of hippocampal cells were obtained from the brains of newborn C57BL/6 mice (P0-P1). On day 7 of culturing, human Lf was added to the medium. After 24 h (day 8 in culture), c-Fos protein was induced in cells by triple application of 50 mM KCl. c-Fos content was analyzed using the immunofluorescent method 2 h after stimulation. Stimulation promoted exogenous Lf translocation into the nuclei of cultured neuronal cells, which correlated with increased induction of transcription factor c-Fos and was accompanied by nuclear colocalization of these proteins. These results attest to the potential of Lf as a modulator of neuronal processes and open up new prospects in studying the mechanisms of the regulatory effects of lactoferrin on cell function.

Abstract
Lactoferrin is an 80 kDa monomeric glycoprotein that exhibits multitask activities. Lactoferrin properties are of interest in the pharmaceutical field for the design of products with therapeutic potential, including nanoparticles and liposomes, among many others. In antimicrobial preparations, lactoferrin has been included either as a main bioactive component or as an enhancer of the activity and potency of first-line antibiotics. In some proposals based on nanoparticles, lactoferrin has been included in delivery systems to transport and protect drugs from enzymatic degradation in the intestine, favoring the bioavailability for the treatment of inflammatory bowel disease and colon cancer. Moreover, nanoparticles loaded with lactoferrin have been formulated as delivery systems to transport drugs for neurodegenerative diseases, which cannot cross the blood-brain barrier to enter the central nervous system. This manuscript is focused on pharmaceutical products either containing lactoferrin as the bioactive component or formulated with lactoferrin as the carrier considering its interaction with receptors expressed in tissues as targets of drugs delivered via parenteral or mucosal administration. We hope that this manuscript provides insights about the therapeutic possibilities of pharmaceutical Lf preparations with a sustainable approach that contributes to decreasing the resistance of antimicrobials and enhancing the bioavailability of first-line drugs for intestinal chronic inflammation and neurodegenerative diseases.

Abstract
Recent studies have shown that the gut microbiome changes brain function, behavior, and psychiatric and neurological disorders. The Gut-Brain Axis (GBA) provides a neuronal pathway to explain this. But exactly how do commensal bacteria signal through the epithelial layer of the large intestine to activate GBA nerve afferents? An in vitro model is described. We differentiated two human cell lines: Caco2Bbe1 into mature epithelium on 0.4-micron filters and then SH-SY5Y into mature neurons in 24-well plates. These were co-cultured by placing the epithelium-laden filters 1 mm above the neurons. Twenty-four hours later they were tri-cultured by apical addition of 107Lactobacillus rhamnosus or Lactobacillus fermentum which settled on the epithelium. Alone, the Caco2bbe1 cells stimulated neurite outgrowth in underlying SH-SY5Y. Beyond this, the lactobacilli were well tolerated and stimulated further neurite outgrowth by 24 h post-treatment, though not passing through the filters. The results provide face validity for a first-of-kind model of transepithelial intestinal lumen-to nerve signaling. The model displays the tight junctional barrier characteristics found in the large intestine while at the same time translating stimulatory signals from the bacteria through epithelial cells to attracted neurons. The model is easy to set-up with components widely available.

Abstract
Lactoferrin (Lf), a bioactive protein initially found in many biological secretions including milk, is regarded as the nutritional supplement or therapeutic ligand due to its multiple functions. Research on its mode of action reveals that intact Lf or its active peptide (i.e., lactoferricin) shows an important multifunctional performance. Oral delivery is considered as the most convenient administration route for this bioactive protein. Unfortunately, Lf is sensitive to the gastrointestinal (GI) physicochemical stresses and lactoferricin is undetectable in GI digesta. This review introduces the functionality of Lf at the molecular level and its degradation behavior in GI tract is discussed in detail. Subsequently, the absorption and transport of Lf from intestine into the blood circulation, which is pivotal to its health promoting effects in various tissues, and some assisting labeling methods are discussed. Stabilization technologies aiming at preserving the structural integrity and functional properties of orally administrated Lf are summarized and compared. Altogether, this work comprehensively reviews the structure-function relationship of Lf, its oral fate and the development of stabilization technologies for the enhancement of the oral bioavailability of Lf. The existing limitations and scope for future research are also discussed.

Abstract
Glycoproteins and glycolipids at the plasma membrane contribute to a range of functions from growth factor signaling to cell adhesion and migration. Glycoconjugates undergo endocytic trafficking. According to the glycolipid-lectin (GL-Lect) hypothesis, the construction of tubular endocytic pits is driven in a glycosphingolipid-dependent manner by sugar-binding proteins of the galectin family. Here, we provide evidence for a function of the GL-Lect mechanism in transcytosis across enterocytes in the mouse intestine. We show that galectin-3 (Gal3) and its newly identified binding partner lactotransferrin are transported in a glycosphingolipid-dependent manner from the apical to the basolateral membrane. Transcytosis of lactotransferrin is perturbed in Gal3 knockout mice and can be rescued by exogenous Gal3. Inside enterocytes, Gal3 is localized to hallmark structures of the GL-Lect mechanism, termed clathrin-independent carriers. These data pioneer the existence of GL-Lect endocytosis in vivo and strongly suggest that polarized trafficking across the intestinal barrier relies on this mechanism.

Han YC, Chiu HF, Ho YT, Venkatakrishnan K, Wang CK. Improved bioavailability of EGCG after complexation with royal jelly protein. J Food Biochem 2020; 44:e13372. [PMID: 32710596 DOI: 10.1111/jfbc.13372] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 06/05/2020] [Accepted: 06/19/2020] [Indexed: 12/20/2022]
Abstract
This study was designed to check whether complexation of royal jelly (RJ) proteins with green tea extract enriched with EGCG, would enhance the bioavailability on C2BBe1 cells. The total phenolic and EGCG of green tea extract (GTex) as well as the protein level of RJ were measured. The best entrapment efficiency (30.47%) was noted at a 10:4 ratio (RJ:EGCG of GTex) to confirm the maximum EGCG-RJ complexation. Followed by in vitro studies to check the cytotoxicity, morphological changes, EGCG uptake, and TBARS (antioxidant) activity were evaluated on C2BBe1 cells. The EGCG-RJ protein complex showed less toxicity without any morphological changes with better cellular EGCG uptake than GTex or GTex-RJ mixture on CeBBe1 cells. Besides, the EGCG-RJ protein complex display maximum TBARS suppressing activity to showcase better stability. This study infers that complexation of RJ proteins with EGCG (EGCG-RJ protein complex) could significantly improve the bioavailability of EGCG. PRACTICAL APPLICATIONS: EGCG is the major active component of green tea, which is responsible for various biological functions. Previous studies have indicated that complexation of EGCG with proteins (act as a carrier) could considerably improve the bioavailability of EGCG. Hence, the author speculates that complexation or combination of RJ with green tea (EGCG), might improve the bioavailability as well as enhance its biological properties. The outcome of this cell line study showed that the EGCG-RJ protein complex showed better bioavailability than EGCG or GTex, and thus, indicating that this novel complex can be used in the future for better EGCG bioavailability with improved biological function. However, further studies are needed to confirm the types of interaction and the reason for better bioavailability.

Abstract
An Intact form of lactoferrin (LF) is known to be absorbed from the small intestine and transported into the blood circulation. We reevaluated the cellular uptake and release of LF using an enterocyte model of human small intestinal cells derived from the Caco-2 cell line. In contrast to a previous report, we observed that intact bovine LF was taken up into seven and 21 d-cultured Caco-2 cells and successfully released back into the culture medium, even though the human intestinal LF receptor, intelectin-1, was not immunochemically detectable. Similar observations were made for human LF and its derivatives (the N-terminal half of LF designated N-lobe and Fc fusions). These observations regarding the uptake and release of intact LF in Caco-2 cells were consistent with in vivo observations. Therefore, we propose that the uptake and release of intact LF by Caco-2 cells should be assessed as a potential in vitro model of in vivo LF absorption in human intestines.

Abstract
Intelectin displays carbohydrate binding capacity and has been demonstrated to agglutinate bacteria, suggesting its role in innate immunity. It has also been linked to many pathogenic conditions in human. After reporting two amphioxus orthologs and the zebrafish intelectin 2 (zITLN2), here we cloned and characterized zebrafish intelectin 1 (zITLN1). Like zITLN2, zITLN1 also contains a conserved fibrinogen-related domain (FReD) and a unique intelectin domain (ITLN-D), expresses in all the tissues tested, with the highest level in intestine, and responds to bacterial challenge in acute phase. We also expressed zITLN1 in E. coli system, and purified recombinant zITLN1 could agglutinate both Gram-positive and Gram-negative bacteria in a calcium dependent manner. Its ability to agglutinate Gram-positive bacteria is stronger than that to Gram-negative bacteria whereas zITLN2 did not show such preference. This is probably due to the fact that recombinant zITLN1 could bind peptidoglycan (PGN) with a higher degree to lipopolysaccharide (LPS). Our results of zITLN1 provided new insight into the evolution and function of the intelectin family.

Abstract
Casein (CN) is the major milk protein to nourish infants but, in certain population, it causes cow's milk allergy, indicating the uptake of antigenic CN and their peptides through the intestinal epithelium. Using human intestinal Caco-2 cell monolayers, the apical-to-basal transepithelial transport of CN was investigated. Confocal microscopy using component-specific antibodies showed that αs1-CN antigens became detectable as punctate signals at the apical-side cytoplasm and reached to the cytoplasm at a tight-junction level within a few hours. Such intracellular CN signals were more remarkable than those of the other antigens, β-lactoglobulin and ovalbumin, colocalized in part with an early endosome marker protein (EEA1) and decreased in the presence of cytochalasin D or sodium azide and also at lowered temperature at 4°C. Liquid chromatography coupled with mass spectroscopy analysis of the protein fraction in the basal-side medium identified the αs1-CB fragment including the N-terminal region and the αs2-CN fragment containing the central part of polypeptide at 100-1,000 fmol per well levels. Moreover, β-CN C-terminal overlapping peptides were identified in the peptide fraction below 10 kDa of the basal medium. These results suggest that CNs are partially degraded by cellular proteases and/or peptidases and immunologically active CN fragments are transported to basal side of the cell monolayers.

Abstract
We examined the in-vitro effects of bovine lactoferrin (LF) on the production of interferon-λ (IFN-λ), an antiviral cytokine important for the defense of enterocytes, using the human intestinal epithelial cell line HT-29. HT-29 cell cultures were treated with LF for 1 h, and the cultures were stimulated with polyinosinic-polycytidylic acid (poly I:C). LF increased the concentration of IFN-λ in the culture supernatant after stimulation in a dose-dependent manner. A similar increase in the concentration of IFN-λ was observed in the supernatant of cells washed between treatment with LF and stimulation with poly I:C. At 6 and 24 h after stimulation with poly I:C (early and late phases, respectively) treated cultures contained significantly higher concentrations of IFN-λ1 in the culture supernatant, and significantly higher IFN-λ1 and IFN-λ2 mRNA levels, than controls. These results suggest that LF activates the innate cellular immunity of the enterocytes to double-stranded RNA and increases the production of IFN-λ.

FISH & SHELLFISH IMMUNOLOGY 2016; 55:729-736. [PMID: 27329687 DOI: 10.1016/j.fsi.2016.06.023] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/07/2016] [Revised: 05/24/2016] [Accepted: 06/18/2016] [Indexed: 06/06/2023]
Abstract
Intelectins are glycan-binding lectins found in various species including cephalochordates, urochordates, fish, amphibians and mammals. But their detailed functions are not well studied in zebrafish which is a good model to study native immunity. In this study, we cloned a zebrafish intelectin ortholog, zebrafish intelectin 2 (zITLN2), which contains a conserved fibrinogen-related domain (FReD) in the N-terminus and the unique intelectin domain in the C-terminus. We examined the tissue distribution of zITLN2 in adult zebrafish and found that zITLN2 was expressed in various organs with the highest level in intestine. Like amphioxus intelectins, zITLN2 expression was upregulated in adult zebrafish infected with Staphylococcus aureus with the highest expression level at 12 h after challenge. Recombinant zITLN2 protein expressed in E. coli was able to agglutinate both Gram-negative and Gram-positive bacteria to similar degrees in a calcium-dependent manner. Furthermore, recombinant zITLN2 bound lipopolysaccharide (LPS) and peptidoglycan (PGN) comparably. Our work on zITLN2 provided further information to understand functions of this new family of lectins and the innate immunity in vertebrates.

Abstract
Fucoidan is a sulfated polysaccharide from brown sea algae. In the present study, it was demonstrated that oral administration of F-fucoidan from Saccharina japonica possessed anti-allergic effects using the passive cutaneous anaphylaxis reaction, but not by intraperitoneal administration. The inhibitory mechanism was dependent on galectin-9, which belongs to a soluble lectin family that recognizes β-galactoside and prevents IgE binding to mast cells. The anti-allergy properties of F-fucoidan were cancelled by an intravenous dose of anti-galectin-9 antibody or lactose, which bind competitively with galectin-9 before the passive cutaneous anaphylaxis reaction. F-fucoidan increased the expression level of galectin-9 mRNA in intestinal epithelial cells and serum galectin-9 levels. Oral treatment with F-fucoidan suppressed allergic symptoms through the induction of galectin-9. This is the first report that F-fucoidan can induce the secretion of galectin-9.

SILAC-based proteomic profiling of the human MDA-MB-231 metastatic breast cancer cell line in response to the two antitumoral lactoferrin isoforms: the secreted lactoferrin and the intracellular delta-lactoferrin. PLoS One 2014; 9:e104563. [PMID: 25116916 PMCID: PMC4130549 DOI: 10.1371/journal.pone.0104563] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2014] [Accepted: 07/10/2014] [Indexed: 11/19/2022] Open
Abstract
Background Lactoferrins exhibit antitumoral activities either as a secretory lactoferrin or an intracellular delta-lactoferrin isoform. These activities involve processes such as regulation of the cell cycle and apoptosis. While lactoferrin has been shown to exert its function by activating different transduction pathways, delta-lactoferrin has been proven to act as a transcription factor. Like many tumor suppressors, these two proteins are under-expressed in several types of cancer, particularly in breast cancer. Methodology/Principal Findings In order to compare the differential effects of the re-introduction of lactoferrin isoforms in breast cancer cells we chose the cancerous mammary gland MDA-MB-231 cell line as a model. We produced a cell line stably expressing delta-lactoferrin. We also treated these cells with fresh purified human breast lactoferrin. We performed two quantitative proteomic studies in parallel using SILAC coupled to mass spectrometry in order to compare the effects of different doses of the two lactoferrin isoforms. The proteome of untreated, delta-lactoferrin expressing and human lactoferrin treated MDA-MB-231 cells were compared. Overall, around 5300 proteins were identified and quantified using the in-house developed MFPaQ software. Among these, expression was increased by 1.5-fold or more for around 300 proteins in delta-lactoferrin expressing cells and 190 proteins in lactoferrin treated cells. At the same time, about 200 and 40 proteins were found to be downregulated (0-0.7-fold) in response to delta-lactoferrin and lactoferrin, respectively. Conclusions/Significance Re-introduction of delta-lactoferrin and lactoferrin expression in MDA-MB-231 mainly leads to modifications of protein profiles involved in processes such as proliferation, apoptosis, oxidative stress, the ubiquitin pathway, translation and mRNA quality control. Moreover, this study identified new target genes of delta-lactoferrin transcriptional activity such as SelH, GTF2F2 and UBE2E1.

Lyar, a cell growth-regulating zinc finger protein, was identified to be associated with cytoplasmic ribosomes in male germ and cancer cells. Mol Cell Biochem 2014; 395:221-9.

Abstract
Translational control is a basic mechanism for gene regulation in cells and important for tissue growth and development in mammals. Deregulation of the mechanism thus causes diseases such as cancer. Considering the importance of the ribosome as a factory of polypeptide synthesis, some new factors have been expected to be associated with the ribosome and involved in translational control. Our proteomic survey for these factors identified a zinc finger protein, Lyar, in cytoplasmic ribosomes of the rodent testis. Subcellular fractionation of the testis provided data supporting association of Lyar with ribosomes. Lyar was then suggested to be included in the 60S large subunit, but not in polysomes, by ultracentrifugation of testicular ribosomes. While analysis of tissue distribution of Lyar has indicated its testis-predominant expression, Lyar mRNA was expressed in the cancer cells originated from tissues other than testis, and Lyar promoted proliferation of NIH-3T3 cells. Furthermore, translation was increased by Lyar in vitro, pointing out the first experimental link between this protein and translation. Taken together, Lyar seems to be a new player in translational control and a potential target for cancer therapy.

Lactoferrin directly scavenges hydroxyl radicals and undergoes oxidative self-degradation: a possible role in protection against oxidative DNA damage. Int J Mol Sci 2014; 15:1003-13.

Abstract
In this study, we examined the protective effect of lactoferrin against DNA damage induced by various hydroxyl radical generation systems. Lactoferrin (LF) was examined with regard to its potential role as a scavenger against radical oxygen species using bovine milk LF. Native LF, iron-saturated LF (holo-LF), and apolactoferrin (apo-LF) effectively suppressed strand breaks in plasmid DNA due to hydroxyl radicals produced by the Fenton reaction. In addition, both native LF and holo-LF clearly protected calf thymus DNA from fragmentation due to ultraviolet irradiation in the presence of H2O2. We also demonstrated a protective effect of all three LF molecules against 8-hydroxydeoxyguanosine (8-OHdG) formation in calf thymus DNA following ultraviolet (UV) irradiation with H2O2. Our results clearly indicate that native LF has reactive oxygen species-scavenging ability, independent of its nature as a masking component for transient metals. We also demonstrated that the protective effect of LF against oxidative DNA damage is due to degradation of LF itself, which is more susceptible to degradation than other bovine milk proteins.

Abstract
Intelectin 1 (IntL) is known as a lectin expressed in intestinal epithelia and also as a receptor for an iron-binding protein, lactoferrin (LF). Uptake of LF with bound iron by enterocytes via receptor-mediated endocytosis has been well investigated, whereas subsequent fate of endocytized LF and LF/IntL complexes remains largely unknown. In the present study, we examined contribution of IntL to the uptake, sub-cellular localization and subsequent release of LF by intestinal Caco-2 IntL-transfectants using two-site ELISA and fluorescence confocal microscopy. LF taken up by IntL-transfectants was immunochemically detected mostly as intact protein in the cell lysates, and it was a little larger in amount than that of the mock-transfectants. In the IntL-transfectants cultured on porous membrane, LF taken up from the apical side was detected immunochemically as punctate signals in the apical-side cytoplasmic region near nucleus. The LF signals were co-localized with IntL and, in a time-dependent manner, partially with early endosome antigen 1 (EEA1), but not with alkaline phosphatase. LF taken up, retained and subsequently released by the IntL-transfectants was larger in amount than that of mock-transfectants. Moreover, uptake of LF altered sub-cellular localization of IntL and markedly enhanced the IntL signals within the cells.
