چکیده

A human glioblastoma cell line was found to express in vitro mRNA transcripts specific for insulin-like growth factor-II (IGF-II) and growth-hormone releasing-hormone (GHRH). In the absence of gross morphological changes, retinoic acid reduced the growth rate without major change of IGF-II mRNA expression, while alpha-difluoromethylornithine produced a complete growth arrest and a sharp decrease of IGF-II mRNA expression. Both reagents increased the expression of GHRH mRNA. Also in this glioblastoma cell line, like other neuroectodermal tumours, IGF-II mRNA is expressed independently from GHRH and seems to be parallel to growth rate.

ANTISENSE RNA TO THE TYPE I INSULIN-LIKE GROWTH FACTOR RECEPTOR REVERSED THE TRANSFORMED PHENOTYPE OF PC-3 HUMAN PROSTATE CANCER CELL LINE IN VITRO

The insulin-like growth factor I receptor (IGF-IR) plays an essential role in the establishment and maintenance of transformed phenotype. Interference with the IGF-IR pathway by antisense causes reversal of the transformed phenotype in many rodent and human tumor cell lines. We stably transfected the PC-3 human prostate cancer cell line with an IGF-IR antisense RNA expression plasmid. The ...

Investigation of the Impact of Foretinib, an Oral Multikinase, on AURKA and AURKB Expression in T98 Glioblastoma Cell Line

Background/Objective: Gliomas are the most common of the primary brain tumors and accounted for more than 40% of all central nervous system (CNS) tumors. Glioblastoma (GBM) remains one of the most fatal human malignancies because of its high angiogenic. Foretinib is an oral multikinase inhibitor that represented antitumor activity in clinical studies.  AURKA and AURKB genes have been shown to b...

Down-Regulation of CD14 Transcripts in Human Glioblastoma Cell Line U87 MG

Background: Pattern recognition receptors (PRRs) are the main sensors of pathogen and danger signals in innate immunity of which Toll Like Receptors (TLRs) are the most studied ones. The contribution of PRRs in cerebral inflammation induced by microbial infection, tissue damage and cancer has not extensively been addressed so far. Glioma is the most common tumor of the central nervous system an...
