Semaphorins and tumor angiogenesis [PDF]
Semaphorins belong to a large family of proteins well-conserved along evolution from viruses to mammalians. Secreted and membrane-bound semaphorins participate in a wide range of biological phenomena including development and regeneration of nervous system, cardiovascular development, and immune system activities.

Semaphorin Breaks Symmetry [PDF]
Axon-dendrite polarity is likely instructed by extrinsic cues in the developing nervous system, though the mechanisms governing this process remain to be fully elucidated. In this issue of Neuron, Shelly et al. show that the axon guidance cue Semaphorin 3A can promote dendrite growth by inhibiting axon specification.

Semaphorin 4C accelerates disease progression and enables disease detection in breast cancer
Semaphorins constitute a diverse family of widely expressed transmembrane, diffusible, and GPI-linked proteins with versatile physiologic functions in orchestrating nerve system development, immune homeostasis, angiogenesis, and cell metabolism ...

Semaphorins in Lung Cancer [PDF]
The secreted class 3 semaphorins, which include SEMA3F, a tumor-suppressor gene in lung cancer, were initially identified as molecules involved in the repulsion of developing nerve growth cones. These molecules are part of a larger family that includes transmembrane and membrane-associated proteins, some of which are expressed widely and implicated in ...

Background Semaphorins were originally identified as molecules regulating a functional activity of axons in the nervous system. Sema4A and Sema4D were the first semaphorins found to be expressed on immune cells and were termed "immune semaphorins". It is

Semaphorins are secreted, transmembrane, and GPI-linked proteins, defined by cysteine-rich semaphorin protein domains, that have important roles in a variety of tissues. Humans have 20 semaphorins, Drosophila has five, and two are known from DNA viruses; semaphorins are also found in nematodes and crustaceans but not in non-animals.

Tgfbr2 in Dental Pulp Cells Guides Neurite Outgrowth in Developing Teeth
Transforming growth factor β (TGFβ) plays an important role in tooth morphogenesis and mineralization. During postnatal development, the dental pulp (DP) mesenchyme secretes neurotrophic factors that guide trigeminal nerve fibers into and throughout the ...
