Expression of IL-6, IL-6 receptor and its signal transducer gp130 mRNAs in megakaryocytic cell lines. 1998

IL-6, its receptor and its transducer protein gp130 mRNAs were analyzed in three cell lines with megakaryocytic properties including CMK, K562, and HEL. Their colony proliferation was also assayed in the methylcellulose medium with or without IL-6. CMK had IL-6, IL-6 receptor and gp130 mRNAs, while the other two cell lines lacked IL-6 receptor mRNA expression. K562 responded to IL-6 indicating that it has an alternative receptor to the so called "IL-6 receptor". HEL was not sensitive to IL-6 suggesting that it proliferates with growth factors other than IL-6 via gp130.

D012333	RNA, Messenger	RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

D015703	Antigens, CD	Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.

D015850	Interleukin-6	A cytokine that stimulates the growth and differentiation of B-LYMPHOCYTES and is also a growth factor for HYBRIDOMAS and plasmacytomas. It is produced by many different cells including T-LYMPHOCYTES; MONOCYTES; and FIBROBLASTS.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D050822	Cytokine Receptor gp130	A cytokine receptor that contains extracellular FIBRONECTIN TYPE III DOMAINS which mediate its function through the formation of oligomeric complexes with itself, or with a variety of CYTOKINE RECEPTORS. It does not bind IL-6, but activates JANUS KINASES and STAT3 TRANSCRIPTION FACTOR.
