This target for cancer of lung cancer with activating mutations therapeuticscell epidermal growth factor receptor, inhibitors such as imatinib mesylate or gefitinib or have cytoreductive effects. A second challenge will be to integrate these new agents in the treatment of cancer in childhood, with the expectation of reducing Vorinostat SAHA the morbidity t and long-term effects of current treatments of Multimodalit t. Agents have been evaluated or evaluated since 2001 in the Phase I or II clinical trials of the children’s Oncology Group and the Working Committee of the p Pediatric brain tumors shows performed in Table 1. This k can Be divided so that the target DNA or histone modifications, targeted toxins, rpern Antique, Anti-angiogenic agents, new drugs, the apoptotic pathways target the proteasome and molecular chaperones in receptor-kinase inhibitors or signaling means, and cytostatics.
The chemical structures for biological active substances are not shown in Figure AZD2171 1. Here we will focus primarily on the signaling inhibitors in development, and as new information is on the molecular genetics of cancer in childhood to create a direct treatments on these properties, which hei t help, the treatment molecular target, is There are several signaling inhibitors clinical trials that focus on the family of ErbB kinase inhibitors or multi-target, some of which are based on the biological characteristics of the p pediatric histiotypes particular Table 2. For example, epidermal growth factor as a mitogen for several histiotypes reported brain tumors, or there is an association of receptor expression with poor prognosis of these tumors increased Ht.
Therefore, targeting ErbB1 is logical. However, if these tumors are dependent on this pathway Ngig is less clear. Be assigned to appear in non-small cell lung tumor regression with activating mutations of ErbB1. Similar data are not available for brain tumors in children. This raises the question whether the inhibition of a single channel represents a realistic therapeutic strategy. For example, tumor cells for PTEN lipid phosphatase, which occurs in childhood glioblastoma seem to mutate best YOUR BIDDING against ErbB1 inhibition, but in these cells both inhibition of Akt signaling and ErbB1 results in hypophosphorylation of the pro-apoptotic Bad molecule, and apoptosis .
Reported in glioblastoma, for example, the EGF signaling is that overexpression canals le IGFI, PDGF, bFGF and HGF SF signaling. Likewise, several growth factors appear to be mitogenic for neuroblastoma, Ewing’s sarcoma and other tumors. Treated thus for an effective treatment for the patient to provide, it may be necessary to inhibit several paths simultaneously. The concern is whether this m Is not possible above the Owned toxicity t. Kinase inhibitors, which seem to be more tolerated, and in certain adult malignancies such as renal cell carcinoma are active, indicating that the inhibition of multiple signaling pathways is a treatment option. Identifying which canals le inhibit specific subsets of tumors of the child, then the challenge. An incomplete Requests reference requests getting list of agents reported inhibit all signal path is shown in Table 2. Another approach to the critical node kinases in signaling cascades that can identify
