The kinesin protein Kif7 has been recognized as an integral component of hedgehog signalling. Aberrant activation of hedgehog signalling has been implicated in many human solid tumours. Gestational trophoblastic disease includes frankly malignant choriocarcinoma and potentially malignant hydatidiform mole. Here we investigated the hedgehog signalling components expression profiles in gestationa...

Antibodies to a synthetic undecapeptide (NH2-Cys-Glu-Asn-Pro-Ser-Gln-Phe-Tyr-Glu-Arg-Leu-COOH), the sequence (except cysteine) of which was deduced from a previously reported cloned human retroviral gag-gene-related DNA sequence erv-1, were raised in rabbits. In immunohistochemical staining these antibodies reacted with normal human first-trimester placentas and with blighted ova and benign and...

Intracerebral hemorrhage can occur due to primary and metastatic intracranial neoplasm. In half of the cases it may be the first manifestation of the tumor. It is also known that metastatic tumors bleed more than the primary CNS tumor [1]. Metastatic choriocarcinoma is a rare but an important cause of intra cerebral hemorrhage in female patients in reproductive age group. Choriocarcinoma (gesta...

The inflammatory gene NLRP7 is the major responsible for recurrent complete hydatidiform moles (CHM), an abnormal pregnancy that can develop into gestational choriocarcinoma (CC). However, role of in development and immune tolerance CC has not been investigated. Three approaches were employed to define development: (i) a clinical study analyzed human placenta sera collected from women with norm...

Breast cancer ranks as a common and severe neoplasia in women with increasing incidence as well as high risk of metastasis and relapse. Translational and laboratory-based clinical investigations of new/novel drugs are in progress. Medicinal plants are rich sources of biologically active natural products for drug development. The 27-kDa trichosanthin (TCS) is a ribosome inactivating protein puri...

Gestational trophoblastic diseases are a heterogenous group of conditions ranging from the benign hydatidiform mole to the malignant choriocarcinoma. Optimal therapy in this group of diseases rest in the correct diagnosis, assessing their risk for malignant behavior using prognostic scoring systems and administering appropriate treatment. Their rarity makes it imperative that these patients are...

Maternal-effect mutations in NLRP7 cause rare biparentally inherited hydatidiform moles (BiHMs), abnormal pregnancies containing hypertrophic vesicular trophoblast but no embryo. BiHM trophoblasts display abnormal DNA methylation patterns affecting maternally methylated germline differentially methylated regions (gDMRs), suggesting that NLRP7 plays an important role in reprogramming imprinted g...

Twenty three hydatidiform moles (HMs) were studied using the techniques of "RFLPs" employing a minisatellite deoxyribonucleic acid probe. Among the 23 HMs, 17 were homozygous types resulting from a duplicated haploid sperm, and two were heterozygous types resulting from fertilization two independent sperms (dispermy). It was revealed that the four histopathologically diagnosed complete HMs (CHM...

The Definitive Haplotype Database (D-HaploDB) is a web-accessible resource of genome-wide definitive haplotypes determined from a collection of Japanese complete hydatidiform moles (CHMs), each of which carries a genome derived from a single sperm. Currently, the database contains genotypes for 281 439 common SNPs from 74 CHMs which were determined by a high-throughput array-based oligonucleoti...
