The mechanisms controlling axon guidance are of fundamental importance in understanding brain development. Growing corticospinal and somatosensory axons cross the midline in the medulla to reach their targets and thus form the basis of contralateral motor control and sensory input. The motor and sensory projections appeared uncrossed in patients with(More)
1. The incorporation and metabolism of (n-3) and (n-6) polyunsaturated fatty acids (PUFA) supplemented to growing cultures were studied in rainbow trout (RTG-2) and turbot (TF) cell lines. 2. A fatty acid concentration of 20 microM considerably altered the fatty acid composition of the cells without affecting lipid class composition or the appearance of(More)
The transcription factor FoxM1 is over-expressed in most human malignancies. Although it is evident that FoxM1 has critical functions in tumour development and progression, the mechanisms by which FoxM1 participates in those processes are not understood. Here, we describe an essential role of FoxM1 in the regulation of oxidative stress that contributes to(More)
When twenty million Walker rat carcinoma cells are injected into the footpad of albino outbred rats, there is progressive metastasis to the draining popliteal and thence para-aortic lymph nodes. The lymphatic duct efferent from the footpad and afferent to the popliteal node has been cannulated; it has been shown that there is a continuous and progressively(More)
When 5 million cells of the solid form 13762 rat mammary carcinoma are implanted into the footpad of syngeneic rats there is consistent (approximately 100%) metastasis to the draining popliteal node and thence up the lymphatic chain to the lungs. With the transmission electron microscope tumor cells are seen to penetrate gaps in the lymphatic endothelium,(More)
We discovered intronic mutations in two episodic ataxia type 2 (EA2) families: a four-nucleotide GAGT deletion at IVS41+(3-6) and a single nucleotide insertion (insT) at IVS24+3. We expressed minigenes harboring the mutations in cell lines to demonstrate exon skipping from the deletion mutation and the activation of a cryptic splice donor site from the(More)
The forkhead box M1b (FoxM1b) transcription factor is over-expressed in human cancers, and its expression often correlates with poor prognosis. Previously, using conditional knockout strains, we showed that FoxM1b is essential for hepatocellular carcinoma (HCC) development. However, over-expression of FoxM1b had only marginal effects on HCC progression.(More)
Malignant neuroblastomas contain stem-like cells. These tumors also overexpress the Forkhead box transcription factor FoxM1. In this study, we investigated the roles of FoxM1 in the tumorigenicity of neuroblastoma. We showed that depletion of FoxM1 inhibits anchorage-independent growth and tumorigenicity in mouse xenografts. Moreover, knockdown of FoxM1(More)
