Description
There are two major subtype of cells in breast cancer. These cancer cells response differently to glutamine deprivation, here we use one luminal type of breast cancer cell (MCF7) and one basal type of breast cancer cell (MDAMB231) to compare the gene expression differences of these two types of cancer cells in glutamine deprivation.

Description
A phase I trial of a SRC kinase Inhibitor, dasatinib, in combination with paclitaxel and carboplatin in patients with advanced or recurrent ovarian cancer. Background: We conducted a phase I study of dasatinib, an oral SRC tyrosine kinase inhibitor, in combination with paclitaxel and carboplatin in advanced and recurrent epithelial ovarian cancer (EOC). Methods: The primary objective was to determine the maximum tolerated dose (MTD). Secondary objectives included toxicity, response rate (RR), pharmacokinetics and pharmacodynamics. Based on the 3+3 design, cohorts of 3-6 pts received paclitaxel 175 mg/m2 and carboplatin AUC 6 every three weeks with escalating doses of dasatinib (100, 120, 150 mg daily), followed by an 8 patient expansion cohort. Results: Twenty patients were enrolled between 06/07 and 12/09. The median age was 61 yrs (42-82) with a median of 2 prior regimens (0-6), and 71% had platinum-sensitive disease. There were 3-6 pts in each cohort, and 8 in the expansion cohort. Pharmacokinetics were observed over the first 2 cycles of therapy. One DLT was observed in the 100 mg dasatinib cohort (grade 3 myalgia. Other toxicities in all cycles included neutropenia (95% grade 3-4), thrombocytopenia (35% grade 3-4), and fatigue (10% grade 3). The RR was 45% (complete responses, 3/18(17%); partial responses, 5/18(28%)) and 56% (10/18) had stable disease. The PFS6-month actuarial estimate was 86%. The median PFS and OS were 7.8 and 16.2 months, respectively. Conclusions: Due to the high incidence of myelosuppression with subsequent cycles the recommended phase II dose is 150 mg daily of dasatinib in combination with paclitaxel and carboplatin. The combination was safe with evidence of clinical activity in advanced EOC.

Description
We applied a meta-analysis of datasets from seven different microarray studies on lung cancer for differentially expressed genes related to survival time (under 2 y and over 5 y). Systematic bias adjustment in the datasets was performed by distance-weighted discrimination (DWD). We identified a gene expression signature consisting of 64 genes that is highly predictive of which stage I lung cancer patients may benefit from more aggressive therapy.

- Affymetrix Poplar Genome Array (poplar)
Description
Previous research has shown that glutamine and sucrose treatment of excised poplar stems induces bark storage protein (BSP) gene expression. The objective of this research is to identify changes in gene expression associated with metabolic regulation of nitrogen storage and cycling and use this information to identify potential regulatory genes. Significant, differentially expressed genes were identified in excised poplar stems incubated in solutions of glutamine, sucrose, glycine, glutamine+glucose, and glutamine+sucrose compared to incubation in a water control.

Description
TCE is a non-genotoxic hepatocarcinogen in mouse, but not in rat or human. Extrapolation of data from laboratory animals to humans is difficult due to species-specific differences. To identify molecular pathways and biological changes responsible for species-specific differences in hepatocarcinogenesis, we analyzed gene expression profiles of livers from B6C3F1 mice and SD rats administered TCE by oral gavage once or repeatedly every 24 hrs for 14 days. Gene expression analysis revealed distinct clusters of transcriptional profiles in single- and repeated-dose mice and rats. Pathway analysis showed differences in biological pathways between single- and repeated-dose mice and rats. Activation of the MAPK signaling cascade and ubiquitin-proteasome inhibitory function, as well as inhibition of TGF-beta signaling, were specific to mice and suggest a role in hepatocyte proliferation. Although pathological analysis showed no evidence of apoptosis, gene expression analysis revealed changes in apoptosis-related genes. In addition to the previously reported suppression of apoptosis, results in repeated-dose mice showed that toxicity induced by TCE in turn induces apoptosis.
