Regulatory effects of glucocorticoids (dexamethasone) on myeloma cells as well as bone resorption in multiple myeloma were investigated. Glucocorticoids significantly inhibited proliferation of myeloma cells, and decreased the messenger RNA (mRNA) expressions of interleukin-6 (IL-6) and secretory type immunoglobulin G (IgG). The inhibitory effects of glucocorticoids on myeloma cell proliferation could be due to the decreased expression of IL-6 mRNA, decreased IL-6 production, and thus suppression of autocrine growth by IL-6, which is an autocrine growth factor for myeloma cells as reported previously (Nature 332:83, 1988). Glucocorticoids also inhibited M-protein secretion by decreasing the levels of secretory type Ig mRNA. On the other hand, because IL-1 beta rather than lymphotoxin is considered to be a major osteoclast activating factor (OAF) produced by myeloma cells, and glucocorticoids decreased the expression of IL-1 beta mRNA and markedly suppressed the bone resorbing activity induced by IL-1 beta OAF in 45Ca-release bone resorption assay, it is suggestive that glucocorticoids could inhibit bone resorption induced by IL-1 beta OAF in multiple myeloma. Therefore, from these data it is concluded that glucocorticoids could be more effective chemotherapeutic agents in multiple myeloma than we expected, especially with regards to the inhibitory effects on proliferation and M-protein secretion from myeloma cells, as well as bone resorption by myeloma cells.

D007375 Interleukin-1 A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.

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.
