Human Chorionic Gonadotropin Beta Subunit Genes CGB1 and CGB2 are Transcriptionally Active in Ovarian Cancer
Human chorionic gonadotropin beta subunit (CGB) is a marker of pregnancy as well as trophoblastic and nontrophoblastic tumors. CGB is encoded by a cluster of six genes, of which type II genes (CGB3/9, 5 and 8) have been shown to be upregulated in relation to type I genes (CGB6/7) in both placentas and tumors. Recent studies revealed that CGB1 and CGB2, originally considered as pseudogenes, migh...
متن کاملLocalization of human chorionic gonadotropin beta subunit transcripts in ovarian cancer tissue.
Recent studies demonstrated that besides placenta and malignant trophoblastic tumors, hCG and especially its beta-subunit is secreted by a varieties of tumors of different origin. The aim of the present investigation was to determine the expression pattern of human chorionic gonadotropin gene in ovarian cancer tissue. The study included 8 patients with epithelial ovarian carcinoma. The expressi...
متن کاملExpression of human chorionic gonadotropin beta subunit genes in superficial and invasive bladder carcinomas.
Increased serum levels of human chorionic gonadotropin beta subunit (hCG beta) were described previously in patients with bladder cancer. To obtain insight into such production of hCG beta, the expression of hCG beta 7, 8, 5, and 3 genes in bladder carcinomas and normal urothelia was investigated by reverse transcription PCR. Surprisingly, hCG beta mRNAs were detected in both normal urothelial ...
متن کاملThe evolution and genomic landscape of CGB1 and CGB2 genes
The origin of completely novel proteins is a significant question in evolution. The luteinizing hormone (LHB)/chorionic gonadotropin (CGB) gene cluster in humans contains a candidate example of this process. Two genes in this cluster (CGB1 and CGB2) exhibit nucleotide sequence similarity with the other LHB/CGB genes, but as a result of frameshifting are predicted to encode a completely novel pr...
متن کاملFine-scale quantification of HCG beta gene transcription in human trophoblastic and non-malignant non-trophoblastic tissues.
Human chorionic gonadotropin (HCG) is produced by syncytiotrophoblast of placenta. It delays the apoptosis of corpus luteum and functions in implantation. Its possible role in male reproduction has been raised. HCG beta subunit is encoded by CGB, CGB5, CGB7 and CGB8 genes located at 19q13.3 in a common genome cluster with beta subunit non-coding CGB1 and CGB2. We conducted a sensitive quantific...
