Semaphorin 3E, an exception to the rule.
Class 3 semaphorins (Sema3s) regulate axon guidance, angiogenesis, tumor growth, and tumor metastasis. Neuropilins (NRPs; NRP1 and NRP2) are the cell surface receptors for the Sema3s. However, to signal, interaction of Sema3s and NRPs with plexins is obligatory. In this issue of the JCI, Casazza and colleagues report data that challenge the conventional wisdom about the role of Sema3s in tumor ...
متن کاملEpigenetically downregulated Semaphorin 3E contributes to gastric cancer
Axon guidance protein Semaphorin 3E (Sema3E) promotes tumor metastasis and suppresses tumor cell death. Here, we demonstrated that Sema3E was decreased in gastric cancer. Its levels were inversely associated with tumor progression. Levels of Sema3E were associated with low p300 and high class I histone deacetylase (class I HDAC). Ectopic expression of Sema3E inhibited proliferation and colony f...
متن کاملEvolution: An exception that proves the rule
A careful comparative analysis suggests a simple explanation for a category of exceptions to the general correlation between separate sexes in plants -- dioecy -- and self-incompatibility. In some genera, polyploidy causes failure of self-incompatibility, and dioecy may then evolve.
متن کاملPhonological dyslexia and phonological impairment: an exception to the rule?
The condition known as phonological dyslexia involves very poor reading of non-words, with otherwise good word reading performance [e.g. Derouesné & Beauvois, 1979; Sartori, G., Barry, C., & Job, R. (1984). Phonological dyslexia: A review. In R. N. Malatesha & H. A. Whitaker (Eds.), Dyslexia: A global issue. The Hague: Martinus Nijhoff Publishers]. Theoretical accounts of this non-word reading ...
متن کاملVEGFR2 (KDR/Flk1) Signaling Mediates Axon Growth in Response to Semaphorin 3E in the Developing Brain
Common factors are thought to control vascular and neuronal patterning. Here we report an in vivo requirement for the vascular endothelial growth factor receptor type 2 (VEGFR2) in axon tract formation in the mouse brain. We show that VEGFR2 is expressed by neurons of the subiculum and mediates axonal elongation in response to the semaphorin (Sema) family molecule, Sema3E. We further show that ...
