Human | HOPX | 84525 | HOP homeobox | Loss of NECC1 expression, biallelic deletions at the critical (7p12-7q11.23) region and enhanced H19 expression in choriocarcinoma would reflect the genetic features exhibited by the putative forerunner, complete mole. | Human | PHLDA2 | 7262 | pleckstrin homology-like domain, family A, member 2 | The product of the imprinted gene IPL marks human villous cytotrophoblast and is lost in complete hydatidiform mole. IPL protein was absent in both of two cases of androgenetic complete hydatidiform mole examined by immunostaining, and IPL mRNA was absent in an additional three cases of this neoplasm examined by northern blotting. | Human | TJP1 | 7082 | tight junction protein 1 | A striking result was the altered expression of ZO-1 and occludin in partial and complete moles. | Human | TIMP1 | 7076 | TIMP metallopeptidase inhibitor 1 | While 8 (73.0%) placentas, 14 (87.5%) partial moles, and 19 (76.0%) complete moles showed strong immunoreactivity for TIMP-1 in syncytiotrophoblasts, no strong staining was found in choriocarcinomas (P < 0.01, P < 0.01, P < 0.01, respectively). METHODS: Paraffin sections of 16 partial moles, 25 complete moles, 10 gestational choriocarcinomas, and 11 normal first-trimester placentas were studied immunohistochemically for expression of MMP-1, MMP-2, MMP-3, MMP-9, MMP-13, and tissue inhibitor of metalloproteinase-1 (TIMP-1). | Human | ST14 | 6768 | suppression of tumorigenicity 14 (colon carcinoma) | To determine the genetic origin of the complete hydatidiform mole, 20 abnormal pregnancies were studied with restriction fragment length polymorphism with five genomic probes: EJ 6.6, beta-globin gene, 3;alpha-hypervariable region, J-Bir, and St14. | Human | PGM1 | 5236 | phosphoglucomutase 1 | In the present study, to shed some light on the genesis of trophoblastic tumor, chromosome, HLA and PGM1 polymorphisms were examined for complete moles and choriocarcinomas. Using chromosomal heteromorphisms, human lymphocyte antigen (HLA) and phosphoglucuromutase 1 (PGM1) polymorphisms, we established the androgenetic origin of complete mole in 84 of 91 cases. Using chromosomal heteromorphism, HLA and PGM1 polymorphisms, we established the androgenetic origin of complete mole in 82 of 91 cases. | Human | NOS3 | 4846 | nitric oxide synthase 3 (endothelial cell) | METHODS: The immunoperoxidase technique with an antibody directed against eNOS was applied to paraffin sections from first and second trimester placentas, placenta accreta, partial and complete hydatidiform moles, and choriocarcinoma. Cells with differentiation to intermediate trophoblast in complete hydatidiform mole and choriocarcinoma also show high levels of eNOS, which may be associated with the haematogenous mode of spread of trophoblastic disease. | Human | NME1 | 4830 | NME/NM23 nucleoside diphosphate kinase 1 | RESULTS: Expression of c-erbB-2 and p53 gene products was significantly increased and expression of nm23 and c-ras products was remarkably decreased in complete hydatidiform moles that progressed into postmolar tumor compared with those that remitted spontaneously after evacuation. We examined the clinical significance of nm23-H1 expression in complete hydatidiform mole. expression of nm23-H1 showed a negative relation to invasion, suggesting its use as a potential marker of myometrial invasion in complete hydatidiform moles Expression of nm23-H1 showed a negative relation to invasion, suggesting its use as a potential marker of myometrial invasion in complete hydatidiform moles. Formalin-fixed paraffin sections of 50 cases of complete mole that progressed to gestational tumor and 32 cases of complete mole that remitted spontaneously were studied immunohistochemically for c-ras, c-erbB-2, p53, and nm23 proteins. INTRODUCTION: There is scant information about the expression of CD44 and E-cadherin, two cell adhesion molecules, and the antimetastatic protein nm23-H1, in complete hydatidiform moles. METHODS: Sections of 105 cases of complete hydatidiform moles (including 25 cases of invasive mole) and 95 cases of gestational age--matched normal placentas were immunohistochemically stained with anti-nm23-H1 antibody, which recognizes the nm23-H1/NDP kinase A gene product. Expression of CD44, E-cadherin, and antimetastatic protein nm23-H1 in complete hydatidiform moles. Expression of nm23-H1 protein in relation to myometrial invasion in complete hydatidiform moles. The relationship between expression of c-ras, c-erbB-2, nm23, and p53 gene products and development of trophoblastic tumor and their predictive significance for the malignant transformation of complete hydatidiform mole. OBJECTIVE: Although nm23-H1 protein expression has been related to invasion in many cancers, its expression and prognostic significance in complete hydatidiform moles has not yet been investigated. CONCLUSION: In this preliminary study, there is no relationship between CD44, E-cadherin, and nm23-H1 expression in complete hydatidiform moles and the risk of invasive disease. OBJECTIVE: The aims of this retrospective study by means of immunohistochemical staining were (1) to study the expression of c-ras, c-erbB-2, p53, and nm23 gene products in complete hydatidiform moles that progress to gestational trophoblastic tumor and in those that remit spontaneously after evacuation, and (2) to estimate the predictive value of the expression of these four gene products in malignant transformation of complete hydatidiform mole. CONCLUSION: nm23-H1 expression could be used as a marker for accurate evaluation of myometrial invasion in complete hydatidiform mole. | Human | RNR1 | 4549 | s-rRNA | This strategy resulted in the isolation of four mitochondrial transcripts downregulated in benign, as well as in malignant, trophoblastic diseases encoding the cytochrome oxidase subunit I (COX I), the ATPase subunit 6, the 12S ribosomal RNA (12S rRNA) and the transfer RNA for phenylalanine (tRNA(Phe)).This expression pattern was confirmed by Northern blot in normal early placenta (NEP), complete hydatidiform mole (CHM), persistent gestational trophoblastic disease (PGTD) and the human choriocarcinoma derived cell line JEG-3. | Human | MMP13 | 4322 | matrix metallopeptidase 13 (collagenase 3) | METHODS: Paraffin sections of 16 partial moles, 25 complete moles, 10 gestational choriocarcinomas, and 11 normal first-trimester placentas were studied immunohistochemically for expression of MMP-1, MMP-2, MMP-3, MMP-9, MMP-13, and tissue inhibitor of metalloproteinase-1 (TIMP-1). | Human | MCM7 | 4176 | minichromosome maintenance complex component 7 | METHODS AND RESULTS: Immunohistochemical staining for MCM7 was performed on 122 samples of paraffin-embedded trophoblastic tissues including 22 normal first-trimester placentas, 12 term placentas, 12 spontaneous miscarriages (SM), 21 partial moles (PM), 44 complete hydatidiform moles (CM), and 11 choriocarcinomas (CCA). | Human | LNPEP | 4012 | leucyl/cystinyl aminopeptidase | In this study, we confirmed the distribution of P-LAP and AP-A proteins and messenger RNAs in human trophoblasts in normal placenta and complete hydatidiform mole by immunohistochemical and in-situ hybridization techniques. Differential distribution of placental leucine aminopeptidase/oxytocinase and aminopeptidase A in human trophoblasts of normal placenta and complete hydatidiform mole. | Human | HLA-G | 3135 | | STUDY DESIGN: We examined 5 complete hydatidiform mole specimens and 5 partial hydatidiform mole specimens to determine whether HLA-G is expressed by immunohistochemistry and by RNA in situ hybridization analysis. Furthermore, expression of HLA-G in the complete hydatidiform mole, a naturally occurring androgenote, confirms expression of the paternal allele of HLA-G. | Human | F2RL2 | 2151 | coagulation factor II (thrombin) receptor-like 2 | Likewise, high expression levels of PAR1 and PAR3 were observed in the cytotrophoblast cells of complete hydatidiform mole as compared to minimal levels in normal age-matched placenta. | Human | ENPEP | 2028 | glutamyl aminopeptidase (aminopeptidase A) | Differential distribution of placental leucine aminopeptidase/oxytocinase and aminopeptidase A in human trophoblasts of normal placenta and complete hydatidiform mole. | Human | DAB2 | 1601 | Dab, mitogen-responsive phosphoprotein, homolog 2 (Drosophila) | Subsequent study using immunohistochemistry showed high levels of DOC-2/hDab2 protein expression in normal trophoblast tissues but significantly lower levels of expression in gestational trophoblastic disease tissues, particularly in complete mole and choriocarcinoma. | Human | CSF1R | 1436 | colony stimulating factor 1 receptor | OBJECTIVE: To determine the expression of bcl-2, c-myc, c-fms and c-erbB-2 oncoproteins in normal placentas, partial and complete hydatidiform moles, and choriocarcinomas and to examine the possible presence of mutations in the K-ras gene in complete moles and choriocarcinomas. CONCLUSION: Our data suggest that c-myc, c-erbB-2, c-fms and bcl-2 oncoproteins may be important in the pathogenesis of complete mole and choriocarcinoma. | Human | CDKN1C | 1028 | cyclin-dependent kinase inhibitor 1C (p57, Kip2) | findings support the hypothesis that misexpression of p57 is involved in the abnormal development of androgenetic complete moles | Human | CCNE1 | 898 | cyclin E1 | The different expression patterns of cyclin E and E2F-1 in partial and complete moles may be useful in distinguishing these two entities. Cyclin E was maximally expressed by complete moles and choriocarcinomas, and showed an inverse relationship with the cyclin-dependent kinase inhibitor p27(kip1). RESULTS: The cyclin E indexes (CEI) were as follows: 25.7% +/- 6.2% for hydropic change, 35.3% +/- 12.7% for triploid partial moles, 42.2% +/- 13.1% for diploid/tetraploid complete moles, and 63.6% +/- 9.5% for choriocarcinomas. In this study we investigated the immunostaining patterns of G(1) restriction point and G(1)-S regulatory proteins E2F-1, Cdk2, cyclin E, p27(kip1), and the proliferation marker Ki-67 on routinely processed sections of 29 hydatidiform moles (10 partial moles and 19 complete moles, including 9 persistent moles), 7 choriocarcinomas, and 7 normal placentas. | Human | ASCL2 | 430 | achaete-scute complex homolog 2 (Drosophila) | Negative expression of HASH2 in complete hydatidiform moles (CM) but positive expression in malignant tumors suggests the presence of a specific mechanism for inactivation of the HASH2 gene in CM and reactivation in invasive moles or choriocarcinoma | Human | APOB | 338 | apolipoprotein B | Five of these revealed DNA segments unique to the paternal APOB allele, allowing us to diagnose a complete mole. |
