Description
We use the zebrafish embryo model to study the innate immune response against polystyrene particles. Therefore, we injected 700nm polystyrene into the yolk at 2 dpf and took samples at 1 and 3 days post injection. Overall design: This deep sequence study was designed to determine the gene expression profile by polystyrene particle toxicity. RNA was isolated from embryos at 1 and 3 days post injection. Wildtypes zebrafish embryos were micro-injected into the yolk (2dpf) with 1nl of 5mg/ml of 700nm red fluorescent polystyrene particles suspended in PVP (Polyvinylpyrrolidone) (n=3), mock injected with pvp (n=2), or Non-injected as a control (n=3). After injections embryos were transferred into fresh egg water and incubated at 28°C. At 1 and 3 days post injection 10 embryos per group were snap-frozen in liquid nitrogen, and total RNA was isolated using TRIZOL reagent.

Description
Brain metastasis is one of the most feared complications of cancer and the most common intracranial malignancy in adults. Its underlying mechanisms remain unknown. From breast cancer patients with metastatic disease we isolated cell populations that aggressively colonize the brain. Transcriptomic analysis of these cells yielded overlapping gene sets whose expression is selectively associated with brain metastasis. The expression of seventeen of these genes in primary breast tumors is associated with brain relapse in breast cancer patients. Some of these genes are also associated with metastasis to lung but not to liver, bone or lymph nodes, providing a molecular basis for the long-observed link between brain and lung metastasis. Among the functionally validated brain metastasis genes, the cyclooxigenase COX-2, the EGFR ligand HB-EGF, and the brain-specific 2-6 sialyltransferase ST6GALNAC5 mediate cancer cell passage through the blood-brain barrier. Other brain metastasis genes encode inflammatory factors and brain-specific proteolytic regulators, suggesting a multifaceted program for breast cancer colonization of the brain.

Description
We previously identified a novel SNF1/AMPK-related protein kinase, Hunk, from a mammary tumor arising in an MMTV-neu transgenic mouse. The function of this kinase is unknown. Using targeted deletion in mice, we now demonstrate that Hunk is required for the metastasis of c-myc-induced mammary tumors, but is dispensable for normal development. Reconstitution experiments revealed that Hunk is sufficient to restore the metastatic potential of Hunk-deficient tumor cells, as well as defects in migration and invasion, and does so in a manner that requires its kinase activity. Consistent with a role for Hunk in the progression of human cancers, the human homologue of Hunk is overexpressed in aggressive subsets of carcinomas of the ovary, colon, and breast. In addition, a murine gene expression signature that distinguishes Hunk-wild type from Hunk-deficient mammary tumors predicts clinical outcome in women with breast cancer. Together, these findings establish a role for Hunk in metastasis and an in vivo function for this kinase.
Publication Title
The Snf1-related kinase, Hunk, is essential for mammary tumor metastasis.

Description
Background: Histologic grade in breast cancer provides clinically important prognostic information. However, 30%-60% of tumors are classified as histologic grade 2. This grade is associated with an intermediate risk of recurrence and is thus not informative for clinical decision making. We examined whether histologic grade was associated with gene expression profi les of breast cancers and whether such profi les could be used to improve histologic grading.
