A Comparative Review of Pregnancy and Cancer and Their Association with Endoplasmic Reticulum Aminopeptidase 1 and 2. Int J Mol Sci 2023; 24:ijms24043454. [PMID: 36834865 PMCID: PMC9965492 DOI: 10.3390/ijms24043454] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/03/2023] [Accepted: 02/06/2023] [Indexed: 02/11/2023] Open
Abstract
The fundamental basis of pregnancy and cancer is to determine the fate of the survival or the death of humanity. However, the development of fetuses and tumors share many similarities and differences, making them two sides of the same coin. This review presents an overview of the similarities and differences between pregnancy and cancer. In addition, we will also discuss the critical roles that Endoplasmic Reticulum Aminopeptidase (ERAP) 1 and 2 may play in the immune system, cell migration, and angiogenesis, all of which are essential for fetal and tumor development. Even though the comprehensive understanding of ERAP2 lags that of ERAP1 due to the lack of an animal model, recent studies have shown that both enzymes are associated with an increased risk of several diseases, including pregnancy disorder pre-eclampsia (PE), recurrent miscarriages, and cancer. The exact mechanisms in both pregnancy and cancer need to be elucidated. Therefore, a deeper understanding of ERAP's role in diseases can make it a potential therapeutic target for pregnancy complications and cancer and offer greater insight into its impact on the immune system.

Abstract
Canine tumors are valuable comparative models for human counterparts, especially to explore novel biomarkers and to understand pathways and processes involved in metastasis. Vasculogenic mimicry (VM) is a unique property of malignant cancer cells which promote metastasis. Thus, it represents an opportunity to investigate both the molecular mechanisms and the therapeutic targets of a crucial phenotypic malignant switch. Although this biological process has been largely investigated in different human cancer types, including osteosarcoma, it is still largely unknown in veterinary pathology, where it has been mainly explored in canine mammary tumors. The presence of VM in human osteosarcoma is associated with poor clinical outcome, reduced patient survival, and increased risk of metastasis and it shares the main pathways involved in other type of human tumors. This review illustrates the main findings concerning the VM process in human osteosarcoma, search for the related current knowledge in canine pathology and oncology, and potential involvement of multiple pathways in VM formation, in order to provide a basis for future investigations on VM in canine tumors.

Abstract
Tumor angiogenesis is a hallmark of liver cancer and is necessary for tumor growth and progression. Supervillin (SVIL) is highly expressed and implicated in several malignant processes of liver cancer. However, the functional relationships between SVIL and tumor angiogenesis in liver cancer have not yet been fully elucidated. The present study was based on bioinformatics analysis, patient tissue sample detection, three-dimensional simulated blood vessel formation, a series of cytological experiments and mouse models. The results demonstrated the important role of SVIL in the progression of malignant liver cancer and tumor angiogenesis, both in terms of vasculogenic mimicry (VM) and endothelium-dependent vessel (EDV) development. SVIL knockdown inhibited VM formation and induced tumor cell apoptosis via the VEGF-p38 signaling axis and through various VM-associated transcriptional factors, including vascular endothelial-cadherin, matrix metalloproteinase 9/12 and migration-inducing protein 7. SVIL may therefore be considered a potential tumor vascular biomarker and a promising therapeutic target for patients with liver cancer.

Abstract
Solid tumors carry out the formation of new vessels providing blood supply for growth, tumor maintenance, and metastasis. Several processes take place during tumor vascularization. In angiogenesis, new vessels are derived from endothelial cells of pre-existing vessels; while in vasculogenesis, new vessels are formed de novo from endothelial progenitor cells, creating an abnormal, immature, and disorganized vascular network. Moreover, highly aggressive tumor cells form structures similar to vessels, providing a pathway for perfusion; this process is named vasculogenic mimicry (VM), where vessel-like channels mimic the function of vessels and transport plasma and blood cells. VM is developed by numerous types of aggressive tumors, including ovarian carcinoma which is the second most common cause of death among gynecological cancers. VM has been associated with poor patient outcome and survival in ovarian cancer, although the involved mechanisms are still under investigation. Several signaling molecules have an important role in VM in ovarian cancer, by regulating the expression of genes related to vascular, embryogenic, and hypoxic signaling pathways. In this review, we provide an overview of the current knowledge of the signaling molecules involved in the promotion and regulation of VM in ovarian cancer. The clinical implications and the potential benefit of identification and targeting of VM related molecules for ovarian cancer treatment are also discussed.

Abstract
Vasculogenic mimicry (VM) is a special type of vascular channel formed by tumor cells without endothelial cell participation. Migration-inducing gene 7 (MIG-7) plays an important role in regulating VM. In this study, immunohistochemical staining was used to detect MIG-7 in tissue specimens from 141 primary osteosarcoma patients, and the relationship between MIG-7 and VM was examined. Survival analysis were performed to evaluate the prognoses. MIG-7 knockdown osteosarcoma cells were used for cell proliferation, apoptosis, migration, invasiveness and VM formation assays. A spontaneously metastasizing cell line-derived orthotopic xenograft mouse model was established to evaluate the effect of MIG-7 knockdown on tumorigenesis, VM formation and lung metastasis. MIG-7 expression was associated with VM formation. There were significant differences in overall and metastasis-free survival between the MIG-7-positive and MIG-7-negative groups. The MIG-7 expression was shown to be an independent indicator of both overall and metastasis-free survival. In vitro knockdown of MIG-7 dramatically reduced migration, invasion and VM formation in osteosarcoma cells without any significant effect on cell proliferation and apoptosis. MIG-7 knockdown also exhibited potent antitumor, antimetastasis and anti-VM effects in the orthotopic mouse model of 143B osteosarcoma. Therefore, MIG-7 serves as an independent unfavorable prognostic indicator in osteosarcoma patients and MIG-7 is an important mediator of osteosarcoma VM formation.

Abstract
Epithelial ovarian carcinomas (EOC) cause more mortality than any other cancer of the female reproductive system. New therapeutic approaches to reduce EOC mortality have been largely unsuccessful due to the poor understanding of the mechanisms underlying EOC proliferation and metastasis. Progress in EOC treatment is further hampered by a lack of reliable prognostic biomarkers for early risk assessment. In this study, we identify that Migration-Inducting Gene 7 (MIG-7) is specifically induced in human EOC tissues but not normal ovaries or ovarian cyst. Ovarian MIG-7 expression strongly correlated with EOC progression. Elevated MIG-7 level at the time of primary cytoreductive surgery was a strong and independent predictor of poor survival of EOC patients. Cell and murine xenograft models showed that MIG-7 was required for EOC proliferation and invasion, and MIG-7 enhanced EOC-associated angiogenesis by promoting the expression of vascular endothelial growth factor. Inhibiting MIG-7 by RNA interference in grafted EOC cells retarded tumor growth, angiogenesis and improved host survival, and suppressing MIG-7 expression with a small molecule inhibitor D-39 identified from the medicinal plant Liriope muscari mitigated EOC growth and invasion and specifically abrogated the expression of vascular endothelial growth factor. Our data not only reveal a critical function of MIG-7 in EOC growth and metastasis and support MIG-7 as an independent prognostic biomarker for EOC, but also demonstrate that therapeutic targeting of MIG-7 is likely beneficial in the treatment of EOC.

Abstract
After oncogenic transformation, tumor cells rewire their metabolism to obtain sufficient energy and biochemical building blocks for cell proliferation, even under hypoxic conditions. Glucose and glutamine become their major limiting nutritional demands. Instead of being autonomous, tumor cells change their immediate environment not only by their metabolites but also by mediators, such as juxtacrine cell contacts, chemokines and other cytokines. Thus, the tumor cells shape their microenvironment as well as induce resident cells, such as fibroblasts and endothelial cells (ECs), to support them. Fibroblasts differentiate into cancer-associated fibroblasts (CAFs), which produce a qualitatively and quantitatively different extracellular matrix (ECM). By their contractile power, they exert tensile forces onto this ECM, leading to increased intratumoral pressure. Moreover, along with enhanced cross-linkage of the ECM components, CAFs thus stiffen the ECM. Attracted by tumor cell- and CAF-secreted vascular endothelial growth factor (VEGF), ECs sprout from pre-existing blood vessels during tumor-induced angiogenesis. Tumor vessels are distinct from EC-lined vessels, because tumor cells integrate into the endothelium or even mimic and replace it in vasculogenic mimicry (VM) vessels. Not only the VM vessels but also the characteristically malformed EC-lined tumor vessels are typical for tumor tissue and may represent promising targets in cancer therapy.

Abstract
Paris polyphylla, a traditional antipyretic-detoxicate chinese medicinal herb, has been applied extensively in cancer treatments for nearly 2000 years. The purpose of the present study is to evaluate the potential anti-osteosarcoma effects of Paris polyphylla ethanol extract (PPEE) and to investigate its underlying mechanisms. The antiproliferation activity of PPEE was tested on 143B, MG-63, U-2 OS and hFOB1.19 cells using MTT assay. The pro-apoptotic and cell cycle arrest effects of PPEE were confirmed by Hoechst 33342 staining and flow cytometry. The antimigratory, anti-invasive and antivasculogenic mimicry (VM) effects of PPEE were investigated by wound healing, Transwell and 3D culture assays. Mouse xenograft model was used to examine its anti-osteosarcoma efficacy in vivo. Hematologic profiles and hepatorenal functions were evaluated to assess the toxicity of PPEE. PPEE evidently suppressed cell proliferation of 143B, MG-63 and U-2 OS with IC50 values of 10-60[Formula: see text][Formula: see text]g/mL, but showed little cytotoxicity against normal osteoblastic cell. PPEE promoted apoptosis in 143B cell via caspase activation, increased Bax/Bcl-2 ratio and PARP cleavage. It also induced G2/M phase arrest associated with elevated phosphorylation of CDK1, Cdc25C, Chk2 and down-regulation of cyclin B1, CDK1, Cdc25C expression. Additionally, PPEE inhibited 143B cell migration, invasion and VM formation at noncytotoxic concentrations through decreasing the expression of FAK, Mig-7, MMP2 and MMP9. Finally, daily oral administration of PPEE for four weeks exhibits potent antitumor and anti-VM activity in 143B xenograft model with low toxicity. Taken together, these findings demonstrated PPEE possesses anti-osteosarcoma and anti-VM activity in vitro and in vivo, and therefore is a potential candidate for osteosarcoma treatment.

Abstract
BACKGROUND Human chorionic gonadotropin (hCG) can play a crucial role in angiogenesis. In the present study, we focused on hCG to gain insight into its potential effects on vasculogenic mimicry (VM) in ovarian cancer cells. METHODS Ovarian cancer OVCAR-3 cells were incubated with different concentrations of recombinant hCG in 3-dimensional cultures. VM was identified by morphological observations and vascular endothelial cell marker detection in OVCAR-3 cells. Expression of hCG, hypoxia-inducible factor-1α (HIF-1α), and the endothelial cell markers CD31, VEGF, and factor VIII were detected by reverse transcription polymerase chain reaction and western blotting. The effect of hCG on endothelial cell-marker expression in ovarian cancer cells was further explored using small interfering RNA (siRNA) and plasmid-based approaches. RESULTS Incubation of OVCAR-3 cells with recombinant hCG induced vessel-like network formation, which was accompanied by significant elevation of vascular marker expression. Attenuation of hCG expression by siRNA in OVCAR-3 cells suppressed the expression of endothelial cell markers and HIF-1α by tumour cells. Overexpression of hCG in OVCAR-3 cells resulted in increased expression of endothelial cell markers and HIF-1α. CONCLUSIONS HCG was crucial for changing the phenotype of OVCAR-3 cells to endothelial-like cells. The effect of hCG induction on VM in ovarian cancer cells is potentially associated with HIF-1α.

Abstract
Development of new cancer therapies based on specific recognition of molecules in cancer cells is a significant challenge, as this requires identification of such molecules (molecular targets) and subsequent development of high-affinity, selective binders (targeting molecules). While several molecular targets for cancer therapies are currently under evaluation in clinical trials, greater selectivity for cancer cells over normal cells is required to enhance efficacy. Migration-inducing gene 7 (Mig-7), a membrane protein found in various types of carcinoma cells, is a cancer-specific biomarker and a promising molecular target for targeted cancer therapies. The purpose of this study was to produce and characterize a novel monoclonal antibody (mAb) raised against an N-terminal peptide of human Mig-7 (Mig-7(1-30)). The Mig-7(1-30) peptide was conjugated with a KLH carrier protein for immunization, and the mAb specific to Mig-7 (STmAb-1) was produced using hybridoma technology. Western blot analysis showed that STmAb-1 specifically reacted with a 23-kDa Mig-7 protein expressed in cancer cell lines, and, crucially, not with primary human fibroblasts. The affinity constant (Kaff) of STmAb-1, as measured by non-competitive enzyme immunoassay, was 1.31 × 10(9) M(-1), indicating high mAb affinity against Mig-7. Immunofluorescence assays demonstrated that STmAb-1 could specifically recognize Mig-7 expressed in cancer cell lines, but not in primary human fibroblasts and keratinocytes. Moreover, STmAb-1 inhibited the growth of MCF7 and HeLa cell lines in contrast to primary human fibroblasts, highlighting its potential usefulness in the development of new cancer therapeutics.

[PMID: 25895023 PMCID: PMC4484471 DOI: 10.18632/oncotarget.3416] [Citation(s) in RCA: 52] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2014] [Accepted: 02/19/2015] [Indexed: 01/05/2023] Open
Abstract
Vasculogenic mimicry (VM) is a blood supply modality that is strongly associated with the epithelial-mesenchymal transition (EMT), TWIST1 activation and tumor progression. We previously reported that metastasis-associated in colon cancer-1 (MACC1) induced the EMT and was associated with a poor prognosis of patients with gastric cancer (GC), but it remains unknown whether MACC1 promotes VM and regulates the TWIST signaling pathway in GC. In this study, we investigated MACC1 expression and VM by immunohistochemistry in 88 patients with stage IV GC, and also investigated the role of TWIST1 and TWIST2 in MACC1-induced VM by using nude mice with GC xenografts and GC cell lines. We found that the VM density was significantly increased in the tumors of patients who died of GC and was positively correlated with MACC1 immunoreactivity (p < 0.05). The 3-year survival rate was only 8.6% in patients whose tumors showed double positive staining for MACC1 and VM, whereas it was 41.7% in patients whose tumors were negative for both MACC1 and VM. Moreover, nuclear expression of MACC1, TWIST1, and TWIST2 was upregulated in GC tissues compared with matched adjacent non-tumorous tissues (p < 0.05). Overexpression of MACC1 increased TWIST1/2 expression and induced typical VM in the GC xenografts of nude mice and in GC cell lines. MACC1 enhanced TWIST1/2 promoter activity and facilitated VM, while silencing of TWIST1 or TWIST2 inhibited VM. Hepatocyte growth factor (HGF) increased the nuclear translocation of MACC1, TWIST1, and TWIST2, while a c-Met inhibitor reduced these effects. These findings indicate that MACC1 promotes VM in GC by regulating the HGF/c-Met-TWIST1/2 signaling pathway, which means that MACC1 and this pathway are potential new therapeutic targets for GC.

Abstract
Vasculogenic mimicry (VM) is a brand-new tumour vascular paradigm independent of angiogenesis that describes the specific capacity of aggressive cancer cells to form vessel-like networks that provide adequate blood supply for tumour growth. A variety of molecule mechanisms and signal pathways participate in VM induction. Additionally, cancer stem cell and epithelial-mesenchymal transitions are also shown to be implicated in VM formation. As a unique perfusion way, VM is associated with tumour invasion, metastasis and poor cancer patient prognosis. Due to VM's important effects on tumour progression, more VM-related strategies are being utilized for anticancer treatment. Here, with regard to the above aspects, we make a review of advanced research on VM in cancer.

Abstract
Growth factors and COX-2/PGE2 enhance lung cancer invasion/metastasis via PI3K/Akt and RAS/Raf. Here, we explored their mechanism of action further. We found first that higher levels of migration inducting gene-7 protein (MIG-7) and PHB phosphorylated at threonine 258 (phospho-PHBT258) are positively correlated with advanced stages of human lung cancer in tissue microarray. PGE2 or growth factors such as EGF, HGF and IGF-1 increased complex formation of phospho-PHBT258 with Ras, phospho-AktS473, phospho-Raf-1S338, MEKK1 and IKKα/βS176/180 in the raft domain transiently within 1 hour and MIG-7 in the cytosol 12-24 hours later. Association of phospho-PHBT258 with MEKK1 but not MEKK3 activates IKK/IκB/NF-κB and MEK/ERK to increase cellular COX-2/PGE2 and an E-cadherin suppressor Snail leading to enhancement of epithelial-mesenchymal transition (EMT) and lung cancer migration/invasion. MIG-7, on the other hand, was induced by growth factors and PGE2 via Akt/GSK-3β in a phospho-PHBT258 independent manner. MIG-7 increased two E-cadherin suppressors ZEB-1 and Twist to enhance EMT and cancer migration/invasion. Downregulating phospho-PHBT258 and MIG-7 had an additive effect on attenuating lung cancer invasion/metastasis and prolonging the survival of xenograft mice. Phospho-PHBT258 and MIG-7 may thus play complementary roles in the initiation and sustainment of the effects of growth factors and COX-2/PGE2 on cancer invasion/metastasis.

Abstract
More effective treatments for metastatic lung cancer remain a pressing clinical need. In this study, we identified migration inducting gene-7 (MIG-7) protein as critical for COX-2/prostaglandin E2 (PGE2)- and Akt/GSK-3β-dependent tumor invasion/metastasis. COX-2/PGE2 activated EP4 to enhance Akt and GSK-3β phosphorylation and β-catenin/T-cell factor/lymphoid enhancer factor signaling leading to MIG-7 upregulation. RNAi-mediated attenuation of MIG-7 blocked COX-2/PGE2- and Akt/GSK-3β-mediated migration/invasion effects. Furthermore, MIG-7 protein inhibited protein phosphatase 2A to sustain Akt/GSK-3β phosphorylation and cancer-cell migration/invasion. Cancer cells overexpressing MIG-7 exhibited increased expression of ZEB-1 and Twist in parallel with epithelial-mesenchymal transition, metastasis and cancer lethality. MIG-7 protein level positively correlated with advanced stages of human lung cancers. MIG-7 thus offers a theranostic target for cancer metastases arising from aberrant activation of the cellular COX-2/PGE2 and Akt/GSK-3β signaling pathways.

Abstract
Background Vasculogenic mimicry (VM), as a new blood supply for tumor growth and hematogenous metastases, has been recently described in highly aggressive human melanoma cells, etc. We previously reported VM in human gallbladder carcinomas and its clinical significance. In this study, we further studied histomorphology and hemodynamic of VM in gallbladder carcinomas in vivo and in vitro. Methods The invasive potential of human gallbladder carcinoma cell lines GBC-SD and SGC-996 were identified by Transwell membrane. The vasculogenic-like network structures and the signal intensities i.e. hemodynamic in gallbladder carcinomas stimulated via the three-dimensional matrix of GBC-SD or SGC-996 cells in vitro, the nude mouse xenografts of GBC-SD or SGC-996 cells in vivo were observed by immunohistochemistry (H&E staining and CD31-PAS double staining), electron microscopy and micro-MRA with HAS-Gd-DTPA, respectively. Results Highly aggressive GBC-SD or poorly aggressive SGC-996 cells preconditioned by highly aggressive GBC-SD cells could form patterned networks containing hollow matrix channels. 85.7% (6/7) of GBC-SD nude mouse xenografts existed the evidence of VM, 5.7% (17/300) channels contained red blood cells among these tumor cell-lined vasculatures. GBC-SD xenografts showed multiple high-intensity spots similar with the intensity observed at tumor marginal, a result consistent with pathological VM. Conclusions VM existed in gallbladder carcinomas by both three-dimensional matrix of highly aggressive GBC-SD or poorly aggressive SGC-996 cells preconditioned by highly aggressive GBC-SD cells in vitro and GBC-SD nude mouse xenografts in vivo.

Abstract
“Vasculogenic mimicry (VM)”, is a term that describes the unique ability of highly aggressive tumor cells to express a multipotent, stem cell-like phenotype, and form a pattern of vasculogenic-like networks in three-dimensional culture. As an angiogenesis-independent pathway, VM and/or periodic acid-schiff-positive patterns are associated with poor prognosis in tumor patients. Moreover, VM is resistant to angiogenesis inhibitors. Here, we will review the advances in research on biochemical and molecular signaling pathways of VM in tumors and on potential anti-VM therapy strategy.

Abstract
Many proliferative, invasive, and immune tolerance mechanisms that support normal human pregnancy are also exploited by malignancies to establish a nutrient supply and evade or edit the host immune response. In addition to the shared capacity for invading through normal tissues, both cancer cells and cells of the developing placenta create a microenvironment supportive of both immunologic privilege and angiogenesis. Systemic alterations in immunity are also detectable, particularly with respect to a helper T cell type 2 polarization evident in advanced cancers and midtrimester pregnancy. This review summarizes the similarities between growth and immune privilege in cancer and pregnancy and identifies areas for further investigation. Our PubMed search strategy included combinations of terms such as immune tolerance, pregnancy, cancer, cytokines, angiogenesis, and invasion. We did not place any restrictions on publication dates. The knowledge gained from analyzing similarities and differences between the physiologic state of pregnancy and the pathologic state of cancer could lead to identification of new potential targets for cancer therapeutic agents.

Abstract
Expression of Migration inducting gene-7 (Mig-7) is limited to tumor cells and to date not found in normal tissues. Multiple tumor microenvironment factors, such as epidermal and hepatocyte growth factors, in concert with alphavbeta5 integrin ligation, induce Mig-7 mRNA expression. Gain or loss of Mig-7 protein studies shows that Mig-7 promotes invasion of colon and endometrial carcinoma cells. These data led us to hypothesize that targeting Mig-7 through various methods could decrease invasion, enhance monocyte cell killing of tumor cells, and inhibit disease progression. To begin testing this hypothesis, an in vitro chemoinvasion assay of endometrial carcinoma cells treated with Mig-7-specific or control antibodies was used. Mig-7 antibody significantly reduced invasion by >60% compared with controls. In another approach to test this hypothesis, an in vitro analysis of peptide-stimulated human peripheral blood monocyte cells and their killing of MCF-7 breast carcinoma cells was used. Mig-7 peptide treatment increased monocyte cell tumor necrosis factor expression and killing of MCF-7 cells 30-fold over no peptide stimulation and 3-fold over MUC-1 or control peptide treatments. Furthermore, stably expressing Mig-7-specific short hairpin RNA resulted in significantly reduced Mig-7 protein levels and early primary tumor growth in a xenograft nude mouse model. Reduced phosphorylation of ERK1/2, Akt, and S6 kinase as well as decreased membrane-type 1 matrix metalloproteinase activity were mechanisms through which Mig-7 protein caused these effects. Based on these collective data, Mig-7 expression could be a potential candidate for future targeted cancer therapies.

Abstract
Vasculogenic mimicry (VM), a term that describes a novel form of angiogenesis-independent microcirculation pattern recently found in few highly aggressive tumors, is formed by tumor cells, rather than endothelial cells. VM is closely correlated with the invasiveness, metastasis and prognosis of related tumors. The presence of VM is associated with an embryonic like phenotype acquired by tumor cells and the biological effects of many proteins. Furthermore, tumor microenvironment also plays an important role in the development of VM. Here, we will review the advances in research on the characteristic, formative mechanisms and clinical significance of VM.

Abstract
Gain or loss of Migration inducting gene-7 (Mig-7) protein expression functional studies suggest it causes aggressive tumor cell invasion and tumor cell vessel-like structure formation. In addition, Mig-7 expression is apparently carcinoma and trophoblast cell-specific. Mig-7 is an example of an atypical gene that is unique in its induction, translation and apparent carcinoma-specific expression. However, studies of this predominantly integral membrane protein are hampered because of the cloning and expression techniques required for detection of Mig-7 protein. Because the encoding region possesses stop codons, repeat sequences and secondary structure, we hypothesized that genetically engineered E. coli are required to maintain the number of purine-pyrimidine repeats and reading frame when producing expression plasmids containing the Mig-7 sequence. Cloning Mig-7 sequence using E. coli genetically engineered to lack recombination and rearrangement capabilities prevented extension of the repeat region. Because of multiple stop codons in the sequence, three different constructs starting from three different reading frame ATG sites were tested for protein production in a human carcinoma cell line. Mig-7 protein of ~23 kD is produced from Mig-7 cDNA that contains multiple stop codons downstream from the ATG in a Kozak consensus sequence. In silico analyses imply that multiple Mig-7 mRNA secondary structures may cause frameshifting, read-through, and/or recoding of the multiple stop codons. Experimental results support that one or more of these translational events take place. In this report, we detail requirements for cloning and expression of this novel, atypical, human gene. These techniques can be used to express this unique protein for further studies.
