Quantitative RT-PCR of relative mRNA content in 13 mouse B-cell lymphomas and plasma cell tumors for 9 key genes. Results of quantitative RT-PCR validation of relative mRNA content in 13 mouse B-cell lymphomas and plasma cell tumors for 9 key genes: expression does not differ significantly between BCLs and PCTs, both groups showing relatively high expression levels. em Jak1 /em also showed higher expression in the BCL group compared to PCTs, but em Jak1 /em is relatively highly expressed, even in PCTs. The accelerating mechanisms engaged after v- em Abl /em infection seems to utilize these pathways (Figure ?(Figure3B),3B), despite the concomitant induction of the counteracting em Socs /em family of genes. These pathways are currently being studied in greater depth at the translational and post-translational levels within the PCT system, following up the leads afforded by our gene expression studies and the initial phosphorylation studies shown here, with the goals of understanding the mechanisms at work. It has been illuminating to analyze our mouse expression data in conjunction with already published Affymetrix data from human multiple myeloma. Cluster analysis showed that human MM1 clustered most closely with PCT4 and PCT5, IL6PC and KiPC, the two groups of PCTs from IL-6-transgenic mice, while the more aggressive myeloma groups, MM3-MM4, clustered more tightly with PCT1 and PCT2, ABLMYCPC and ABPC, those with appearance accelerated by em v- /em Abl activity. This similarity includes differences in expression of genes associated with proliferation. This was unexpected but significant, because plasma cell neoplasms are not generally associated with rapid proliferation. Instead, increased survival or escape from apoptosis is thought to be the chief mechanism responsible for the expansion of lymphocytes or plasma cells in lymph nodes or bone marrow, respectively. This similarity brings to mind the possibility that Imatinib, the activated Abl inhibitor, might be effective in treating aggressive myeloma patients. This co-clustering suggests that different pathways can be utilized to achieve a similar outcome, namely transformation of plasma cells. Thus, the mouse PCT model, despite its biological differences from MM, offers an experimental model for studying the details of the etiology of plasma cell neoplasms with different degrees of aggressiveness, much as seen in human myelomas. This aspect of our research will end up being broadened to add brand-new data on extra myeloma sufferers [29] where expression data are accustomed to define seven subgroups that differ within their molecular features. This scholarly study would be the subject of another manuscript. Bottom line Lymphoid plasma and change cell tumor development are challenging, multi-stage processes, so it is essential to research these procedures using study equipment covering genome-wide shifts in expression prospectively. The present research implies that gene appearance profiling can differentiate B-cell lymphomas from plasma cell tumors and in addition distinguish gradual from accelerated plasma cell tumors. These outcomes and data extracted from the awareness of v-Abl-accelerated plasma cell tumors and their phosphorylated STAT proteins to the consequences of STI-571 indicate these usually similar tumors make use of different signaling pathways but talk about a common initiating hereditary lesion, a c- em Myc /em -activating chromosome translocation. This research of gene appearance information of mouse B-cell lymphomas and many subclasses of plasma cell tumors provides data offering signs for the knowledge of B-cell neoplasia and plasma cell tumor development as well as the interpretation from the potential plasma cell tumor induction research that are actually under way.

Conclusion Lymphoid transformation and plasma cell tumor formation are complicated, multi-stage processes, so it is necessary to study these processes prospectively using research tools covering genome-wide changes in expression. The present study shows that gene expression profiling can differentiate B-cell lymphomas from plasma cell tumors and also distinguish slow from accelerated plasma cell tumors. These results and data obtained from the sensitivity of v-Abl-accelerated plasma cell tumors and their phosphorylated STAT proteins to the effects of STI-571 indicate that these normally similar tumors utilize different signaling pathways but share a common initiating genetic lesion, a c- em Myc /em -activating chromosome translocation. This study of gene expression profiles of mouse B-cell lymphomas and several subclasses of plasma cell tumors provides data that offer clues for the understanding of B-cell neoplasia and plasma cell tumor formation and the interpretation of the prospective plasma cell tumor induction studies that are now under way.
