CD133, also known as prominin-1, was first described as a cell surface marker on early progenitor and hematopoietic stem cells. It is a five-domain transmembrane protein composed of an N-terminal extracellular tail, two small cytoplasmic loops, two large extracellular loops containing seven potential glycosylation sites, and a short C-terminal intracellular tail. CD133 has been used as a marker to identify cancer stem cells derived from primary solid tumors and as a prognostic marker of gliomas. Herein, we developed novel anti-CD133 monoclonal antibodies (mAbs) and characterized their efficacy in flow cytometry, Western blot, and immunohistochemical analyses...

The epidermal growth factor receptor (EGFR) is a member of the human epidermal growth factor receptor (HER) family of receptor tyrosine kinases and is involved in cell growth and differentiation. EGFR homodimers or heterodimers with other HER members, such as HER2 and HER3, activate downstream signaling cascades in many cancers. In this study, we developed novel anti-EGFR monoclonal antibodies (mAbs) and characterized their efficacy in flow cytometry, Western blot, and immunohistochemical analyses. First, we expressed the full-length or ectodomain of EGFR in LN229 glioblastoma cells and then immunized mice with LN229/EGFR or ectodomain of EGFR, and performed the first screening using enzyme-linked immunosorbent assays...

Podocalyxin is a CD34-related type I transmembrane protein that is highly glycosylated with N-glycan, O-glycan, and keratan sulfate. Podocalyxin was originally found in the podocytes of rat kidney and is reportedly expressed in many types of tumors, including brain tumors, colorectal cancers, and breast cancers. Overexpression of podocalyxin is an independent predictor of progression, metastasis, and poor outcome. We recently immunized mice with recombinant human podocalyxin, which was produced using LN229 glioblastoma cells, and produced a novel antipodocalyxin monoclonal antibody (mAb), PcMab-47, which reacts with endogenous podocalyxin-expressing cancer cell lines and normal cell lines independent of glycosylation in Western blot, flow cytometry, and immunohistochemical analyses...

Podoplanin (PDPN) is expressed in several normal tissues, such as lymphatic endothelial cells, podocytes of renal glomerulus, and type I alveolar cells of lung. PDPN activates platelet aggregation by binding to C-type lectin-like receptor-2 (CLEC-2) on platelet. Although monoclonal antibodies (mAbs) against human PDPN, mouse PDPN, rat PDPN, rabbit PDPN, dog PDPN, and bovine PDPN have been established, anticat PDPN (cPDPN) mAbs have not been developed. In this study, we immunized mice with Chinese hamster ovary (CHO)-K1 cell lines expressing cPDPN, and developed anti-cPDPN mAbs...

Human lipocalin 6 (hLCN6) is a member of the lipocalin family, which is a group of structurally conserved hydrophobic ligand binding proteins, and widely distributed in animal, plant, and bacteria. Specific expression of hLCN6 in the epididymis and localization of this protein on the surface of spermatozoa suggest a role played by hLCN6, which may function as a transporter to carry ligands in the epididymal channel. However, the role of hLCN6 in sperm maturation has been largely unknown due to the lack of effective antibodies...

The chicken glucocorticoid-induced leucine zipper (chGILZ) participates in the inflammation of avian immunosuppressive diseases. We aimed to establish a monoclonal antibody (MAb) against chGILZ and to investigate its distribution in clinical diagnosis. A gene cloned from chicken embryo fibroblast (CEF) cell was inserted into the expression vector pET-28a and pGEX-6p-1. The recombinant expression vectors were transformed into Escherichia coli BL21 (DE3). Then the recombinant proteins His-chGILZ and GST-chGILZ were successfully expressed and purified...

Diacylglycerol kinase (DGK) is responsible for the enzymatic conversion of diacylglycerol to phosphatidic acid. Since both diacylglycerol and phosphatidic acid serve as signaling molecules, DGK is regarded as a hub between diacylglycerol-mediated and phosphatidic acid-mediated signaling. One of the 10 DGK isozymes, DGKα, is shown to be involved in T cell function. Transfection studies using tagged expression vectors revealed that DGKα localizes to the cytoplasm and nucleus and translocates to the plasma membrane in response to T cell receptor stimulation...

Pancreatic carcinoma is the fourth leading cause of cancer death and is characterized by early invasion and metastasis. Advances in molecular biology directed new strategies in targeted therapy using monoclonal antibodies. To identify new biomarkers, we generated a panel of monoclonal antibodies against the newly established cell line, Faraz-ICR, from a patient with acinar cell carcinoma. After immunization of BALB/c female mice with Faraz-ICR cell line and fusion of splenocytes with SP2/0 myeloma cell line, high reactive hybridoma producing antibodies to Faraz-ICR were detected using enzyme-linked immunosorbent assay, immunofluorescence staining and flow cytometry...

More recently, alternative splicing of specific genes are investigated for their therapeutic potential. In particular, we reported the existence of BCR-ABL alternative splicing isoforms, in about 80% of Philadelphia-positive patients, which lead to the expression of aberrant proteins. These fusion proteins are characterized by an orphan initial and correct Bcr portion attached to a 112 amino acid sequence, arising from the impairment in the reading frame (reading of ABL exon 4 and 5). We demonstrated that these Abl-out-of-frame (OOF) isoforms could have an immunological role with therapeutic implications...

Human epidermal growth factor receptor 2 (HER2) plays a critical role in the progression of breast cancers, and HER2 overexpression is associated with poor clinical outcomes. Trastuzumab is an anti-HER2 humanized antibody that leads to significant survival benefits in patients with HER2-positive metastatic breast cancers. In this study, we developed novel anti-HER2 monoclonal antibodies (mAbs) and characterized their efficacy in flow cytometry, Western blot, and immunohistochemical analyses. Initially, we expressed the full length or ectodomain of HER2 in LN229 glioblastoma cells and then immunized mice with ectodomain of HER2 or LN229/HER2, and performed the first screening by enzyme-linked immunosorbent assays using ectodomain of HER2...

Podocalyxin (PODXL) is expressed in several cancers, including brain tumors and colorectal cancers. PODXL overexpression is an independent predictor of progression, metastasis, and poor outcome. We recently immunized mice with recombinant human PODXL, which was produced using LN229 glioblastoma cells, and produced a clone PcMab-47 that could be used for investigating PODXL expression by flow cytometry and immunohistochemical analysis. Herein, we produced a human-mouse chimeric PcMab-47 (chPcMab-47) and investigated its antitumor activity against PODXL-expressing tumors...

High mobility group box 1 (HMGB1) is a key member of the "danger associated molecular patterns" (DAMPs), which can localize in various compartments of the cell, and plays important roles in systemic inflammation. In the present study, monoclonal antibodies (MAbs) specifically against chicken HMGB1 were generated. The open reading frame of chicken HMGB1 was amplified by RT-PCR and cloned into the prokaryotic expression vector pET-28a to construct a recombinant plasmid pET-chHMGB1. The recombinant chicken HMGB1 protein was expressed in Escherichia coli Rosetta under IPTG induction and then purified by Ni-NTA Purification System...

IgA nephropathy (IgAN) is a globally common primary glomerulonephritis characterized by an elevated level of serum IgA and immune complex deposition in the mesangial area. In the serum of patients with IgAN, the hinge region of IgA1 immunoglobulin contains aberrantly glycosylated O-glycans deficient in galactose, which is normally added to the core 1 O-glycan structure by core 1 synthase, glycoprotein-N-acetylgalactosamine 3-beta-galactosyltransferase 1 (C1GALT1), the key enzyme in the process of glycosylation...

Repair of DNA damage is vital to the health and survival of all organisms. In Escherichia coli, a protein known as RadA (or Sms) participates in recombinational repair, a process that uses an undamaged DNA strand in one DNA duplex to fill a gap in a homologous DNA strand in a sister DNA duplex. In a prior report, we described the production of monoclonal antibodies (MAbs) specific for RadA. Here, we investigated the epitopes recognized by two of the antibodies, MAbs 6F5 and 2A2. Premature stop codons (ochre mutations) were introduced into the radA gene at selected sites, and the truncated RadA proteins were probed by western blotting...
