Abstract
Non-Small Cell Lung Carcinoma (NSCLC) remains a leading cause of cancer death. Resistance to therapy is a significant problem, highlighting the need to find new ways of sensitising tumour cells to therapeutic agents. βIII-tubulin is associated with aggressive tumours and chemotherapy resistance in a range of cancers including NSCLC. βIII-tubulin expression has been shown to impact kinase signalling in NSCLC cells. Here, we sought to exploit this interaction by identifying co-activity between βIII-tubulin suppression and small-molecule kinase inhibitors. To achieve this, a forced-genetics approach combined with a high-throughput drug screen was used. We show that activity of the multi-kinase inhibitor Amuvatinib (MP-470) is enhanced by βIII-tubulin suppression in independent NSCLC cell lines. We also show that this compound significantly inhibits cell proliferation among βIII-tubulin knockdown cells expressing the receptor tyrosine kinase c-Met. Together, our results highlight that βIII-tubulin suppression combined with targeting specific receptor tyrosine kinases may represent a novel therapeutic approach for otherwise difficult-to-treat lung carcinomas.

Abstract
Metaplasia, dysplasia, and cancer arise from normal epithelia via a plastic cellular transformation, typically in the setting of chronic inflammation. Such transformations are the focus of numerous studies that strive to identify the changes in RNA/Protein expression that drive such plasticity along with the contributions from the mesenchyme and immune cells. However, despite being widely utilized clinically as biomarkers for such transitions, the role of glycosylation epitopes is understudied in this context. Here, we explore 3'-Sulfo-Lewis A/C, a clinically validated biomarker for high-risk metaplasia and cancer throughout the gastrointestinal foregut: esophagus, stomach, and pancreas. We discuss the clinical correlation of sulfomucin expression with metaplastic and oncogenic transformation, as well as its synthesis, intracellular and extracellular receptors and suggest potential roles for 3'-Sulfo-Lewis A/C in contributing to and maintaining these malignant cellular transformations.

PLoS One 2021; 16:e0261082. [PMID: 34910746 PMCID: PMC8673611 DOI: 10.1371/journal.pone.0261082] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 11/23/2021] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION Multiple previous studies have shown the monoclonal antibody Das-1 (formerly called 7E12H12) is specifically reactive towards metaplastic and carcinomatous lesions in multiple organs of the gastrointestinal system (e.g. Barrett's esophagus, intestinal-type metaplasia of the stomach, gastric adenocarcinoma, high-grade pancreatic intraepithelial neoplasm, and pancreatic ductal adenocarcinoma) as well as in other organs (bladder and lung carcinomas). Beyond being a useful biomarker in tissue, mAb Das-1 has recently proven to be more accurate than current paradigms for identifying cysts harboring advanced neoplasia. Though this antibody has been used extensively for clinical, basic science, and translational applications for decades, its epitope has remained elusive. METHODS In this study, we chemically deglycosylated a standard source of antigen, which resulted in near complete loss of the signal as measured by western blot analysis. The epitope recognized by mAb Das-1 was determined by affinity to a comprehensive glycan array and validated by inhibition of a direct ELISA. RESULTS The epitope recognized by mAb Das-1 is 3'-Sulfo-Lewis A/C (3'-Sulfo-LeA/C). 3'-Sulfo-LeA/C is broadly reexpressed across numerous GI epithelia and elsewhere during metaplastic and carcinomatous transformation. DISCUSSION 3'-Sulfo-LeA/C is a clinically important antigen that can be detected both intracellularly in tissue using immunohistochemistry and extracellularly in cyst fluid and serum by ELISA. The results open new avenues for tumorigenic risk stratification of various gastrointestinal lesions.

Abstract
Background Heritable factors are well known to increase the risk of cancer in families. Known susceptibility genes account for a small proportion of all colorectal cancer cases. The aim of this study was to identify the genetic background in a family suggested to segregate a dominant cancer syndrome with a high risk of rectal- and gastric cancer. We performed whole exome sequencing in three family members, 2 with rectal cancer and 1 with gastric cancer and followed it up in additional family members, other patients and controls. Results We identified 12 novel non-synonymous single nucleotide variants, which were shared among 5 affected members of this family. The mutations were found in 12 different genes; DZIP1L, PCOLCE2, IGSF10, SUCNR1, OR13C8, EPB41L4B, SEC16A, NOTCH1, TAS2R7, SF3A1, GAL3ST1, and TRIOBP. None of the mutations was suggested as a high penetrant mutation. It was not possible to completely rule out any of the mutations as contributing to disease, although seven were more unlikely than the others. Neither did we rule out the effect of all thousands of intronic, intergenic and synonymous variants shared between the three persons used for exome sequencing. Conclusions We propose this family, suggested to segregate dominant disease, could be an example of complex inheritance.

Abstract
C-type lectins on dendritic cells function as antigen uptake and signaling receptors, thereby influencing cellular immune responses. Dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) is one of the best-studied C-type lectin receptors expressed on DCs and its glycan specificity and functional requirements for ligand binding have been intensively investigated. The carbohydrate specificity of dendritic cell immunoreceptor (DCIR), another DC-expressed lectin, was still debated, but we have recently confirmed DCIR as mannose/fucose-binding lectin. Since DC-SIGN and DCIR may potentially share ligands, we set out to elucidate the interaction of DCIR with established DC-SIGN-binding ligands, by comparing the carbohydrate specificity of DCIR and DC-SIGN in more detail. Our results clearly demonstrate that DC-SIGN has a broader glycan specificity compared to DCIR, which interacts only with mannotriose, sulfo-Lewis(a), Lewis(b) and Lewis(a). While most of the tested DC-SIGN ligands bound DCIR as well, Candida albicans and some glycoproteins on some cancer cell lines were identified as DC-SIGN-specific ligands. Interestingly, DCIR strongly bound human immunodeficiency virus type 1 (HIV-1) gp140 glycoproteins, while its interaction with the well-studied DC-SIGN-binding HIV-1 ligand gp120 was much weaker. Furthermore, DCIR-specific ligands were detected on keratinocytes. Furthermore, the interaction of DCIR with its ligands was strongly influenced by the glycosylation of DCIR. In conclusion, we show that sulfo-Lewis(a) is a high affinity ligand for DCIR and that DCIR interacts with ligands from both pathogenic and endogenous origin of which most are shared by DC-SIGN.

Abstract
Inflammation is defined as the normal response of living tissue to injury or infection. It is important to emphasize two components of this definition. First, that inflammation is a normal response and, as such, is expected to occur when tissue is damaged. Infact, if injured tissue does not exhibit signs of inflammation this would be considered abnormal and wounds and infections would never heal without inflammation. Secondly, inflammation occurs in living tissue, hence there is need for an adequate blood supply to the tissues in order to exhibit an inflammatory response. The inflammatory response may be triggered by mechanical injury, chemical toxins, and invasion by microorganisms, and hypersensitivity reactions. Three major events occur during the inflammatory response: the blood supply to the affected area is increased substantially, capillary permeability is increased, and leucocytes migrate from the capillary vessels into the surrounding interstitial spaces to the site of inflammation or injury. The inflammatory response represents a complex biological and biochemical process involving cells of the immune system and a plethora of biological mediators. Cell-to-cell communication molecules such as cytokines play an extremely important role in mediating the process of inflammation. Inflammation and platelet activation are critical phenomena in the setting of acute coronary syndromes. An extensive exposition of this complex phenomenon is beyond the scope of this article (Rankin 2004).

Abstract
To study the roles of microRNA-223 (miR-223) in regulation of cell growth, we established a miR-223 over-expression model in HeLa cells infected with miR-223 by Lentivirus pLL3.7 system. We observed in this model that miR-223 significantly suppressed the proliferation, growth rate, colony formation of HeLa cells in vitro, and in vivo tumorigenicity or tumor formation in nude mice. To investigate the mechanisms involved, we scanned and examined the potential and putative target molecules of miR-223 by informatics, quantitative PCR and Western blot, and found that insulin-like growth factor-1 receptor (IGF-1R) was the functional target of miR-223 inhibition of cell proliferation. Targeting IGF-1R by miR-223 was not only seen in HeLa cells, but also in leukemia and hepatoma cells. The downstream pathway, Akt/mTOR/p70S6K, to which the signal was mediated by IGF-1R, was inhibited as well. The relative luciferase activity of the reporter containing wild-type 3′UTR(3′untranslated region) of IGF-1R was significantly suppressed, but the mutant not. Silence of IGF-1R expression by vector-based short hairpin RNA resulted in the similar inhibition with miR-223. Contrarily, rescued IGF-1R expression in the cells that over-expressed miR-223, reversed the inhibition caused by miR-223 via introducing IGF-1R cDNA that didn't contain the 3′UTR. Meanwhile, we also noted that miR-223 targeted Rasa1, but the downstream molecules mediated by Rasa1 was neither targeted nor regulated. Therefore we believed that IGF-1R was the functional target for miR-223 suppression of cell proliferation and its downstream PI3K/Akt/mTOR/p70S6K pathway suppressed by miR-223 was by targeting IGF-1R.

Abstract
Carbohydrate structures with a 3'-sulfo betaGal linkage, such as 3'-sulfo-Le(x), can be synthesized by Gal:3-O-sulfotransferase-2 (Gal3ST-2) catalysis, but little is known about their roles in many biological processes. To investigate the role of Gal3ST-2 and its product 3'-sulfo-Le(x), we depleted Gal3ST-2 via siRNA and added exogenous Lewis-x trisaccharide 3'-sulfate sodium salt in human SMMC7721 hepatoma cells. After siRNA transfection, a striking morphological change in SMMC7721 hepatoma cells from polygon to shuttle shape and a significant decrease in the level of adhesion to sL-selectin, HUVEC, fibronectin, vitronectin, and fibrinogen were observed. The expression of integrin subunit alphaV was markedly downregulated, and 3'-sulfated subunit alphaV almost disappeared in the transfectants. The level of cell surface integrin alphaVbeta3 was reduced simultaneously, although total subunit beta3 underwent almost no change. After treatment with exogenous Lewis-x 3'-sulfate, cellular integrin subunit alphaV was upregulated and the level of cell surface integrin alphaVbeta3 was elevated. Interestingly, knockdown of Gal3ST-2 expression effectively inhibited cell proliferation, and the result was significantly correlated with the decrease in the levels of ILK, phosphorylated AKT, and ERK. On the other hand, treatment with Lewis-x trisaccharide 3'-sulfate sodium salt greatly upregulated the phosphorylation of AKT and ERK. Our results also indicated that downregulation of Gal3ST-2 via siRNA transfection was associated with the decrease in the level of expression of anti-apoptotic protein, Bcl-2, with a consequent decrease in the ratios for Bcl-2 to Bax. By exposure to Lewis-x trisaccharide 3'-sulfate sodium salt, the apoptotic response of cells was inhibited. Therefore, Gal3ST-2 and its product, 3'-sulfo-Le(x), were involved in regulation of integrin subunit alphaV and might be associated with cancer cell regulation.
