NEU4 inhibits motility of HCC cells by cleaving sialic acids on CD44. Oncogene 2021; 40:5427-5440. [PMID: 34282273 DOI: 10.1038/s41388-021-01955-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 06/19/2021] [Accepted: 07/09/2021] [Indexed: 02/07/2023]
Abstract
Hepatocellular carcinoma (HCC) is an extremely metastatic tumor. Sialic acids (SAs) are associated with cancer development and metastasis. NEU4 is a sialidase that removes SAs from glycoconjugates, while the function of the NEU4 in HCC has not been clearly explored. In our research, we found the NEU4 expression was significantly down-regulated in HCC tissues, which was correlated with high grades and poor outcomes of HCC. The NEU4 expression could be regulated by histone acetylation. In the functional analysis of NEU4, the cell motility was inhibited when NEU4 was overexpressed, and restored when NEU4 expression was down-regulated. Similarly, NEU4 over-expressed HCC cells showed less metastasis in athymic nude mice. Further study revealed that NEU4 could inhibit cell migration by enzymatic decomposition of SAs. Our results verified a NEU4 active site (NEU4E235) and overexpressing inactivates NEU4E235A that weakens the inhibition ability to cell migration. Further, 70 kinds of specific interacting proteins of NEU4 including CD44 were identified through mass spectrum. Moreover, the α2,3-linked SAs on CD44 were decreased and the hyaluronic acid (HA) binding ability was increased when NEU4 over-expressed or activated. Additionally, the mutation of CD44 with six N-glycosylation sites showed less sensibility to NEU4 on cell migration compared with wild-type CD44. In summary, our results revealed the mechanism of low expression of NEU4 in HCC and its inhibitory effect on cell migration by removal of SAs on CD44, which may provide new treatment strategies to control the motility and metastasis of HCC.

Abstract
Extracellular matrix (ECM) is a non-cellular three-dimensional macromolecular network composed of collagens, proteoglycans/glycosaminoglycans, elastin, fibronectin, laminins, and several other glycoproteins. Matrix components bind each other as well as cell adhesion receptors forming a complex network into which cells reside in all tissues and organs. Cell surface receptors transduce signals into cells from ECM, which regulate diverse cellular functions, such as survival, growth, migration, and differentiation, and are vital for maintaining normal homeostasis. ECM is a highly dynamic structural network that continuously undergoes remodeling mediated by several matrix-degrading enzymes during normal and pathological conditions. Deregulation of ECM composition and structure is associated with the development and progression of several pathologic conditions. This article emphasizes in the complex ECM structure as to provide a better understanding of its dynamic structural and functional multipotency. Where relevant, the implication of the various families of ECM macromolecules in health and disease is also presented.

Abstract
Extensive experimental evidence in cell and animal tumor models show that hyaluronan-CD44 interactions are crucial in both malignancy and resistance to cancer therapy. Because of the intimate relationship between the hyaluronan-CD44 system and tumor cell survival and growth, it is an increasingly investigated area for applications to anticancer chemotherapeutics. Interference with the hyaluronan-CD44 interaction by targeting drugs to CD44, targeting drugs to the hyaluronan matrix, or interfering with hyaluronan matrix/tumor cell-associated CD44 interactions is a viable strategy for cancer treatment. Many of these methods can decrease tumor burden in animal models but have yet to show significant clinical utility. Recent advances in nanomedicine have offered new valuable tools for cancer detection, prevention, and treatment. The enhanced permeability and retention effect has served as key rationale for using nanoparticles to treat solid tumors. However, the targeted and uniform delivery of these particles to all regions of tumors in sufficient quantities requires optimization. An ideal nanocarrier should be equipped with selective ligands that are highly or exclusively expressed on target cells and thus endow the carriers with specific targeting capabilities. In this review, we describe how the hyaluronan-CD44 system may provide such an alternative in tumors expressing specific CD44 variants.

Abstract
Targeted molecular imaging with hyaluronic acid (HA) has been highlighted in the diagnosis and treatment of CD44-overexpressing cancer. CD44, a receptor for HA, is closely related to the growth of cancer including proliferation, metastasis, invasion, and angiogenesis. For the efficient detection of CD44, we fabricated a few kinds of HA-modified MnFe2O4 nanocrystals (MNCs) to serve as specific magnetic resonance (MR) contrast agents (HA-MRCAs) and compared physicochemical properties, biocompatibility, and the CD44 targeting efficiency. Hydrophobic MNCs were efficiently phase-transferred using aminated polysorbate 80 (P80) synthesized by introducing spermine molecules on the hydroxyl groups of P80. Subsequently, a few kinds of HA-MRCAs were fabricated, conjugating different ratios of HA on the equal amount of phase-transferred MNCs. The optimized conjugation ratio of HA against magnetic content was identified to exhibit not only effective CD44 finding ability but also high cell viability through in vitro experiments. The results of this study demonstrate that the suggested HA-MRCA shows strong potential to be used for accurate tumor diagnosis.

Abstract
It is becoming increasingly clear that signals generated in tumor microenvironments are crucial to tumor cell behavior, such as survival, progression and metastasis. The establishment of these malignant behaviors requires that tumor cells acquire novel adhesion and migration properties to detach from their original sites and to localize to distant organs. CD44, an adhesion/homing molecule, is a major receptor for the glycosaminoglycan hyaluronan, which is one of the major components of the tumor extracellular matrix. CD44, a multistructural and multifunctional molecule, detects changes in extracellular matrix components, and thus is well positioned to provide appropriate responses to changes in the microenvironment, i.e. engagement in cell-cell and cell-extracellular matrix interactions, cell trafficking, lymph node homing and the presentation of growth factors/cytokines/chemokines to co-ordinate signaling events that enable the cell responses that change in the tissue environment. The potential involvement of CD44 variants (CD44v), especially CD44v4-v7 and CD44v6-v9, in tumor progression has been confirmed for many tumor types in numerous clinical studies. The downregulation of the standard CD44 isoform (CD44s) in colon cancer is postulated to result in increased tumorigenicity. CD44v-specific functions could be caused by their higher binding affinity than CD44s for hyaluronan. Alternatively, CD44v-specific functions could be caused by differences in associating molecules, which may bind selectively to the CD44v exon. This minireview summarizes how the interaction between hyaluronan and CD44v can serve as a potential target for cancer therapy, in particular how silencing CD44v can target multiple metastatic tumors.

Abstract
Myofibroblasts are contractile cells that are characterized by the expression of alpha-smooth muscle actin and mediate the closure of wounds and the formation of collagen-rich scars. Their presence in organs such as lungs, liver, and kidney has long been established as a marker of progressive fibrosis. The transforming growth factor beta(1)-driven differentiation of fibroblasts is a major source of myofibroblasts, and recent data have shown that hyaluronan is a major modulator of this process. This study examines this differentiation mechanism in more detail. Transforming growth factor beta(1)-dependent differentiation to the myofibroblastic phenotype was antagonized by the inhibition of hyaluronan synthesis, confirming that hyaluronan was necessary for differentiation. This response, however, was not reproduced by simply adding hyaluronan to fibroblasts, as the results implicated hyaladherins, as well as the macromolecular assembly of de novo hyaluronan, as essential in this process. We previously suggested that there is a relocalization of lipid-raft components during myofibroblastic differentiation. The present study demonstrates that the hyaluronan receptor CD44, the hyaluronidase HYAL 2, and the transforming growth factor beta(1)-receptor ALK5 all relocalized from raft to non-raft locations, which was reversed by the addition of exogenous hyaluronan. These data highlight a role for endogenous hyaluronan in the mediation of myofibroblastic differentiation. While hyaluronan synthesis was both essential and necessary for differentiation, exogenously provided hyaluronan antagonized differentiation, underscoring a pathological role for hyaluronan in such cell fate processes.

Abstract
We have shown recently that cDNA vaccination, using a virtual lymph node, ameliorates experimental allergic encephalomyelitis. Successful cure from mammary tumor requires resolution of local tumor growth and metastases. We have examined whether targeting of CD44 cell surface adhesion molecule by cDNA vaccination plays a role in resolving mammary tumor development. We show here that CD44 cDNA vaccination decreases the tumor mass and metastatic potential in experimental mammary tumor of BALB/c mice. Vaccination of mice, inoculated with the mammary tumors, by cDNA of CD44 variant (CD44v) but not by cDNA of standard CD44, markedly reduced local tumor development and lung metastasis. Concomitantly, transfection of CD44 antisense into a highly metastatic mammary tumor cell line disrupted the CD44 expression of the cells and reduced their ability to establish local tumors as well as metastatic colonies in the lung. Moreover, when CD44v, but not standard CD44 sense cDNA, was transfected into the poorly metastatic cell line, tumor development was markedly enhanced. It is possible therefore that DNA vaccination with a specific CD44v construct could induce an immune resistance to mammary tumor progression.

Abstract
The complex system involved in the synthesis, degradation and binding of the high molecular weight glycosaminoglycan hyaluronic acid (hyaluronan or HA) provides a variety of structures that can be exploited for targeted cancer therapy. In many cancers of epithelial origin there is an upregulation of CD44, a receptor that binds HA. In other cancers, HA in the tumor matrix is overexpressed. Both CD44 on cancer cells and HA in the matrix have been targets for anticancer therapy. Even though CD44 is expressed in normal epithelial cells and HA is part of the matrix of normal tissues, selective targeting to cancer is possible. This is because macromolecular carriers predominantly extravasate into the tumor and not normal tissue; thus CD44-HA targeted carriers administered intravenously localize preferentially into tumors. Anti-CD44 antibodies have been used in patients to deliver radioisotopes or mertansine for treatment of CD44 expressing tumors. In early phase clinical trials, patients with breast or head and neck tumors treated with anti-CD44 conjugates experienced stabilized disease. A dose-limiting toxicity was associated with distribution of the antibody-drug conjugate to the skin, a site in the body with a high level of CD44. HA has been used as a drug carrier and a ligand on liposomes or nanoparticles to target drugs to CD44 overexpressing cells. Drugs can be attached to HA via the carboxylate on the glucuronic acid residue, the hydroxyl on the N-acetylglucosamine or the reducing end which are located on a repeating disaccharide. Drugs delivered in HA-modified liposomes exhibited excellent antitumor activity both in vitro and in murine tumor models. The HA matrix is also a potential target for anticancer therapies. By manipulating the interaction of HA with cell surface receptors, either by degrading it with hyaluronidase or by interfering with CD44-HA interactions using soluble CD44 proteins, tumor progression was blocked. Finally, cytotoxic drugs or prodrug converting enzymes can be attached to the HA matrix to generate a cytotoxic fence around the tumor. This review describes how the complex interplay among cancer biology, the CD44-HA interaction, drug carriers and drug targeting has been used to improve anticancer therapies. As these approaches evolve, they hold forth the prospect of significantly improved targeted anticancer treatments.

Abstract
Tumor progression is substantially dependent on network of multiple factors, including adhesion and homing molecules, which support the malignant metastatic spread. CD44, one of the adhesion/homing molecules, has attracted much attention not only because it is expressed on many types of tumors, but also owing to its numerous functions, such as supporting cell migration and transmitting survival signals, thereby being pro-oncogenic by nature. We have used the mouse malignant LB lymphoma cell line as a model for comprehensive in vitro and in vivo analyses of the interaction between CD44 and hyaluronic acid (HA), and its relevance to tumor dissemination. The in vitro studies revealed that LB cells could not bind HA, either under static or dynamic (i.e., shear flow) conditions, unless their CD44 is activated by phorbol ester, deglycosylated (to increase the CD44 positive net charge) or transfected with CD44 variants. In parallel, in vivo experiments showed that LB cell dissemination could be controlled by injection of anti-CD44 monoclonal antibodies or hyaluronidase. Furthermore, LB cells transfected with CD44v4-v10 variant, rather than standard CD44, displayed enhanced invasion of the peripheral lymph nodes. This effect was completely lost if the HA binding site of CD44 were mutated. LB cell accumulation in the lymph nodes is caused by enhanced migration via the afferent lymphatics rather than by accelerated proliferation within the lymph node. This information can be exploited to tailor a "therapeutic suit" that should be maximally effective in inducing tumor resistance, while minimizing destructive side effects.

Abstract
Phosphatase and tensin homolog deleted on chromosome 10 (Pten) is a tumor suppressor protein whose loss of lipid phosphatase activity is associated with lymphomagenesis. We made use of the Cre-loxP system to delete Pten expression in Lck- or CD4-expressing T-lineage cells. Mice initially showed modest thymic hyperplasia and subsequently developed expanding and infiltrating T-cell lymphomas, leading to a premature death within 5 to 23 weeks. Frequently, all thymocyte and peripheral T-cell populations displayed phenotypes characteristic for immature developing thymocyte precursors and shared elevated levels of clonally rearranged T-cell receptor (TCR) beta chains. In concert, CD2, CD5, CD3epsilon and CD44, proteins associated with increased expression and signaling capacity of both the immature pre-TCR and the mature alphabetaTCR, were more abundantly expressed, reflecting a constitutive state of activation. Although most T-cell lymphomas had acquired the capability to infiltrate the periphery, not all populations left the thymus and expanded clonally exclusively in the thymus. In line with this, only transplantation of thymocytes with infiltrating capacity gave rise to T-cell lymphoma in immunodeficient recipients. These results indicate that T-cell-specific Pten deletion during various stages of thymocyte development gives rise to clonally expanding T-cell lymphomas that frequently infiltrate the periphery, but originate in the thymus.

Abstract
Although blood monocytes exhibit significant cytotoxic activity against tumor cells, the function of tumor infiltrating macrophages (TIM) is depressed in cancer patients. This study addresses the question of how the antitumor response of human monocytes, assessed by production of cytokines (tumor necrosis factor alpha, TNF; IL-10; IL-12p40) and cytotoxicity, is altered by exposure to cancer cells. Tumor cell--pre-exposed monocytes restimulated with tumor cells showed significantly decreased production of TNF, IL-12, increased IL-10 (mRNA and release) and inhibition of IL-1 receptor-associated kinase-1 (IRAK-1) expression. This down-regulation of cytokine production was selective, as the response of pre-exposed monocytes to lipopolysaccharide (LPS) was unaffected. Treatment of tumor cell--pre-exposed monocytes with hyaluronidase (HAase) improved their depressed production of TNF, while HAase-treated cancer cells did not cause monocyte dysfunction. The response of hyaluronan (HA)--pre-exposed monocytes to stimulation with tumor cells was also inhibited. Cytotoxic activity of monocytes pretreated with cancer cells was also decreased. This study shows that tumor cells selectively deactivate monocytes and suggests that tumor cell-derived HA by blocking CD44 on monocytes inhibits their antitumor response. These observations may provide some explanation for the depressed function of TIM in human malignancy.

Abstract
Tissue anoxia occurs early in wound healing. This is accompanied by production of lactate followed by increased hyaluronan and CD44 expression, suggesting a cause and effect relationship. Fibroblasts increased hyaluronan and CD44 when lactate was added to cultures. Increased deposition of hyaluronan correlates with greater turnover. In current models of hyaluronan catabolism, it is tethered to cell surfaces by CD44 in caveolin-enriched invaginations. It is cleaved to 20-kDa fragments by Hyal-2 on the plasma membrane, endocytosed, and delivered ultimately to lysosomes, and further digested by Hyal-1. Sequence analyses of promoter regions of genes for CD44, caveolin-1, Hyal-1, and -2 revealed multiple AP-1 and ets-1 response elements. To test their relevance, RNA from lactate-treated fibroblasts was analyzed by reverse transcriptase-polymerase chain reaction. Increased transcripts of c-fos, c-jun, c-ets, Hyal-1, -2, CD44, and caveolin-1 mRNAs were observed. We have thus identified lactate-activated genes important in the wound healing responses. Similar responses facilitating tumor progression, the Warburg effect, may share such mechanisms.

Abstract
CD44 is a multistructural and multifunctional cell surface molecule involved in cell proliferation, cell differentiation, cell migration, angiogenesis, presentation of cytokines, chemokines, and growth factors to the corresponding receptors, and docking of proteases at the cell membrane, as well as in signaling for cell survival. All these biological properties are essential to the physiological activities of normal cells, but they are also associated with the pathologic activities of cancer cells. Experiments in animals have shown that targeting of CD44 by antibodies, antisense,and CD44-soluble proteins markedly reduces the malignant activities of various neoplasms, stressing the therapeutic potential of anti-CD44 agents. Furthermore, because alternative splicing and posttranslational modifications generate many different CD44 sequences, including, perhaps, tumor-specific sequences, the production of anti-CD44 tumor-specific agents may be a realistic therapeutic approach. However, in many cancers (renal cancer and non-Hodgkin's lymphomas are exceptions), a high level of CD44 expression is not always associated with an unfavorable outcome. On the contrary, in some neoplams CD44 upregulation is associated with a favorable outcome. Even worse, in many cases different research grows analyzing the same neoplastic disease reached contradictory conclusions regarding the correlation between CD44 expression and disease prognosis, possibly due to differences in methodology. These problems must be resolved before applying anti-CD44 therapy to human cancers.

Abstract
Osteoclast (OC) precursors migrate to putative sites of bone resorption to form functionally active, multinucleated cells. The preOC FLG 29.1 cells, known to be capable of irreversibly differentiating into multinucleated OC-like cells, displayed several features of primary OCs, including expression of specific integrins and the hyaluronan (HA) receptor CD44. OC-like FLG 29.1 cells adhered to and extensively migrated through membranes coated with fibronectin, vitronectin, and laminins, but, although strongly binding to HA, totally failed to move on this substrate. Moreover, soluble HA strongly inhibited OC-like FLG 29.1 cell migration on the permissive matrix substrates, and this behavior was dependent on its engagement with CD44, as it was fully restored by function-blocking anti-CD44 antibodies. HA did not modulate the cell-substrate binding affinity/avidity nor the expression levels of the corresponding integrins. MMP-9 was the major secreted metalloproteinase used by OC-like FLG 29.1 cells for migration, because this process was strongly inhibited by both TIMP-1 and GM6001, as well as by MMP-9-specific antisense oligonucleotides. After HA binding to CD44, a strong down-regulation of MMP-9 mRNA and protein was detected. These findings highlight a novel role of the HA-CD44 interaction in the context of OC-like cell motility, suggesting that it may act as a stop signal for bone-resorbing cells.

Abstract
Multidrug resistance (MDR) lines from a murine T-cell lymphoid leukemia were selected in increasing vincristine (VCR) or doxorubicin (DOX) concentrations. Surface markers were determined by flow cytometry in both resistant (LBR-V 160 and LBR-D 160) and sensitive (LBR-) cell lines. Results obtained revealed similar expression of CD25, CD24, CD8, CD4, C18 and CD44, while differences in binding to hyaluronic acid (HA) were found. LBR- and LBR-D 160 bound to HA only after phorbol ester (PMA) activation, while LBR-V160 failed to bind HA even after PMA treatment. Histopathological analysis disclosed that LBR-V160 was less invasive than LBR- and LBR-D160 cell lines. In vitro growth of cell lines analyzed by sulforhodamine-B uptake showed that doubling time for the three lines was 10.24 h (LBR-), 16.75 h (LBR-V160) and 16.29 h (LBR-D160). Mortality rate was determined after i.p. injection of 10(4) cells. Mice inoculated with LBR- died at 23 2.11) days, while those inoculated with LBR-V160 or LBR-D160 died at 41 (+/- 9.53) or 41 (+/- 4.96) days, respectively. Our results demonstrated that leukemic murine T cells cultured in the long-term presence of VCR or DOX not only presented changes in the resistance phenotype but also variations in their growth and metastatic pattern.

Abstract
Interaction between hyaluronic acid (HA) and CD44 has been considered a key event in tumor invasion and metastasis. HA is a linear, high molecular weight glycosaminoglycan in its native state, but fragmented low molecular forms are found at sites ofneoplastic or inflammatory infiltrates. Both high and low molecular weights HA are involved in diverse biological functions. In this study, we used two clonal variants of a T cell murine lymphoma designated LBLa and LBLc. These cell lines were found to differ in their in vivo and in vitro growth rates. LBLa grew faster and exhibited an enhanced invasive capacity as compared to LBLc. In contrast, cell lines did not differ in the expression of surface markers (CD8, CD24, CD25, CD44, and CD18), or in their capacity to bind HA. However, LBLa cells exhibited higher capacity to migrate to low molecular weight HA than did LBLc. Migration was mediated by CD44 since it was abrogated by anti-CD44 monoclonal antibody as well as by hyaluronidase. We suggest that interaction between CD44 and low molecular weight HA may trigger migration mechanisms in LBLa cells, thus contributing to enhanced invasive cell capacity.

Abstract
Maneuvers that interfere with signals 1, 2, 3, or Ag processing can result in indefinite allograft survival. However, they are not applicable to all tissues, strains, or species, suggesting that there are additional levels of immune regulation. We hypothesized that secondary lymphoid organs are important for interactions among lymphocytes, alloantigen, and immunosuppressants that lead to tolerance. To explore this, cardiac allografts were performed with a tolerogenic immunosuppressive regimen. Concurrent administration of anti-L-selectin (CD62L) Ab, which prevents lymph node homing, prevents indefinite allograft survival and tolerance. Anti-CD62L Ab is not costimulatory, and Fab and F(ab')(2) anti-CD62L have similar activities. Flow cytometry and histologic examination show that Ab shifts T cells away from lymph nodes and into spleen, peripheral blood, and graft. Tolerance is not induced in CD62L(-/-) mice, and adoptive transfer of CD62L(-/-), but not CD62L(+/+), T cells prevents tolerization in wild-type recipients. FTY720, an immunosuppressant that promotes chemokine-dependent, but CD62L-independent, lymph node homing, reverses the Ab effect. Blockade of other homing receptors also prevents tolerization. These results indicate that T lymphocytes use CD62L-dependent migration for alloantigen-specific tolerance, and suggest that lymph nodes or other lymphoid tissues are an important site for peripheral tolerization to alloantigen.

Abstract
Cell motility is an essential element of tumor dissemination, allowing organ infiltration by cancer cells. Using mouse LB lymphoma cells transfected with standard CD44 (CD44s) cDNA (LB-TRs cells) or with the alternatively spliced CD44 variant CD44v4-v10 (CD44v) cDNA (LB-TRv cells), we explored their CD44-dependent cell migration. LB-TRv cells, but not LB-TRs or parental LB cells, bound soluble hyaluronic acid (HA) and other glycosaminoglycans (GAGs), and exclusively formed, under physiological shear force, rolling attachments on HA substrate. Furthermore, LB-TRv cells, but not LB-TRs cells or their parental LB cells, displayed accelerated local tumor formation and enhanced accumulation in the peripheral lymph nodes after s.c. inoculation. The aggressive metastatic behavior of i.v.-injected LB-TRV cells, when compared with that of other LB-transfectants, is attributed to more efficient migration to the lymph nodes, rather than to local growth in the lymph node. Injection of anti-CD44 monoclonal antibody or of the enzyme hyaluronidase also prevented tumor growth in lymph nodes of BALB/c mice inoculated with LB-TRv cells. The enhanced in vitro rolling and enhanced in vivo local tumor growth and lymph node invasion disappeared in LB cells transfected with CD44v cDNA bearing a point mutation at the HA binding site, located at the distal end of the molecule constant region. These findings show that the interaction of cell surface CD44v with HA promotes cell migration both in vitro and in vivo, and they contribute to our understanding of the mechanism of cell trafficking, including tumor spread.
