Scientists at IRB Barcelona have discovered that some brain tumours in larvae of the fruit fly Drosophila melanogaster use the genetic programme of germline cells to grow.
Fluorescent microscopy makes use of molecules, such as green fluorescent protein (GFP), that emit colored light when illuminated with light of a specific wavelength.
Could viewing cell behavior in three dimensions lead to important advances in cancer research?
Investigators at Sanford-Burnham Medical Research Institute have discovered that the natural compound sceptrin, which is found in marine sponges, reduces cancer cell motility (movement) and has very low toxicity.
Study shows FAK coordinates movement of migrating cancer cells.
Metastasis is the ability of cancer cells to spread from a primary site, to form tumours at distant sites. It is a complex process in which cell motility and invasion play a fundamental role. Essential to our understanding of how metastasis develops is identification of the molecules, and characterisation of the mechanisms that regulate cell motility. Hitherto, these mechanisms have been poorly understood. Now, a team of researchers lead by Professor Marco Falasca at Barts and The London...
By Zhu, Hui Chen, Tao; Zhu, Maosheng; Fang, Qing; Kang, Heng; Hong, Zonglie; Zhang, Zhongming During the establishment of symbiosis in legume roots, the rhizobial Nod factor signal is perceived by the host cells via receptor-like kinases, including SymRK.
By Guo, Woei-Jiun Ho, Thun-Hua David Plant HVA22 is a unique abscisic acid (ABA)/stress-induced protein first isolated from barley (Hordeum vulgare) aleurone cells. Its yeast homolog, Yop1p, functions in vesicular trafficking and in the endoplasmic reticulum (ER) network in vivo.
By Zhao, Qiao Brkljacic, Jelena; Meier, Iris Ran GTPase plays essential roles in multiple cellular processes, including nucleocytoplasmic transport, spindle formation, and postmitotic nuclear envelope (NE) reassembly.
