(Okayama, Japan, 20 September 2012) From pioneering insights into water splitting/photosynthesis and analysis of the Itokawa asteroid brought to Earth by Japan's Hayabusa space probe, to stemming the spread of cancer and identification of a rice transporter for manganese and cadmium uptake—the Okayama University e-Bulletin highlights a wide range of pioneering research and related activities at Okayama University.

Research highlights featured in the September 2012 issue of Okayama University e-Bulletin include:

Evolving planets get a bumpy ride

Asteroids are considered to comprise intermediate products in the evolution of solar bodies. The Japan Aerospace Exploration Agency (JAXA) sent a probe to investigate the near-Earth asteroid 25143 Itokawa with the aim of learning more about the evolution of the solar system. Eizo Nakamura and colleagues at Okayama University and the Japan Aerospace Exploration Agency (JAXA) have now studied samples retrieved by the probe — the first reported analysis of grains taken directly from a solar body in space.

Stemming the spread of cancer

Cancer stem cells (CSCs) have been proposed as an explanation for the spread of cancer. These cells are tumorigenic and have the capacity of both self-renewal and differentiation into a range of various cell types. In this concept, malignant tumors provide heterogeneous aspects derived from CSCs as well as normal stem cells provide tissue specific phenotype in response to their microenvironment.

Identification of a rice transporter for manganese and cadmium uptake

Rice (Oryza sativa) is an important dietary source of cadmium and can accumulate very high levels of manganese without toxic effects. However so far there has been little understanding of the uptake and transport mechanisms for these minerals. In depth studies by Jian Feng Ma and colleagues at Okayama University in Japan have revealed how OsNramp5, a member of the natural resistance macrophage protein (Nramp) family, enables uptake of specific minerals in rice.

Water splitting: Ultrahigh resolution data reveals reaction mechanisms

http://app.aaas-science.org/e/er?s=1906&lid=20735&elq=d722a92dad22433fb302cf72e5d798e2

Oxygenic photosynthetic organisms utilize energy from the sun to split water into protons, electrons and oxygen — products vital to life on earth. The process takes place through light-induced electron transfer reactions in a membrane protein complex photosystem II, but so far the resolution of structural studies on the protein complex has been too limited to ascertain the mechanism of these reactions in detail.
