Hierarchical clustering was then conducted using Euclidean distance and Wards minimal vCNX-2006 ariance for agglomer ation, The ensuing heat map proven that the cells from 2D and 3D cultures had Gene expression strikingly different protein expression patterns and that the protein expression pattern of the cells from 3D cultures more closely resembled that of patient areas than did the protein expression pattern of cells grown on monolayer, Most of the proteins that display a definite expression pattern between 2D and 3D cultures play key roles in cell growth, specifically, the G1 to S transition, These results were expected because it has-been established that the 3D culture system is a more physiologically relevant model than cell culture on a 2D plastic exterior for the study of cellular actions, Furthermore, within an unsupervised analysis of the patient RPPA data, we noticed separate clustering between the, low and high LMW E revealing breast tumors although not between low and high full-length cyclin E, We next determined the proteins whose expression was significantly associated with LMW E levels as well as patient survival within the tumor databases, Our analysis revealed that the b Raf ERK12 mTOR pathway is activated in the breast cancer patient samples as well as inside the tumor cells cultured on Matrigel with high LMW E expression, Furthermore, a primary comparison between the levels of all of the proteins analyzed in Figure 5C by Western blot and those obtained from the RPPA analysis showed high concordance and also checked the activation of this signaling axis in vitro, Additionally, breast cancer patient tumors with high LMW E expression also expressed high levels of b Raf, pMEK12, ERK2, mTOR, and eIF4E and a low degree of pAkt, Collectively, these data suggested that in terms of proteomic expression patterns, breast cancer cells grown in 3D culture more closely mimic human tumors than do breast cancer cells grown in 2D culture thus underscoring the effectiveness of this in vitro model system. Combination drug treatment inhibits induction of aberrant acinar development by LMW E Having recognized the value of the CDK2 associated kinase activity in aberrant acinar morphogenesis in 3D culture SCH772984 and given that the m Raf ERK12 mTOR signaling axis was deregulated in tumor cells and patient samples with high LMW E expression, we hypothesized that combination treatment with roscovitine plus either rapamycin or sorafenib can avoid the induced aberrant acinar mor phology. Combination treatments of cells cultured in Matrigel utilizing these agents led to a larger reduced total of the levels of pS6, pERK12, and pRb than no treatment or treatment with individual agents, Moreover, the combination treatments upregulated the expres sion of the CDK inhibitors p21 and p27, consistent with a cell-cycle arrest in the G1 S phase.
