Project funded by Kieikai (2015): Mechanisms and functions of L-amino acid(s) to adapt heat-stress
2015.04～2016.03, 代表者：Vishwajit S. Chowdhury, Nakashima Foundation, Japan
Worldwide, heat stress is a billion dollar problem. Institute for Global Change Adaptation Science (ICAS) at Ibaraki Univ. reported that the Agriculture in Kyushu is already severely affected
by climate change. ICAS suggested that if no action is taken now, the economic cost of climate change to Japan could be as high as ¥17 trillion annually by the end of the century. Therefore, it is very urgent to develop adaption of living organisms under changing climate. Global warming inducing high ambient temperature is a resultant of climate change. Poultry birds are very sensitive to heat stress [Chowdhury et al., 2012, 2014]. Recently, I confirmed that L-citrulline (L-Cit) clearly reduced body temperature in heat exposed chicks. Another research of mine, supported by Kiekai Research Grant, revealed that L-alanine showed declining body temperature, but not as strong as L-Cit. Therefore, I am interested to conduct further research using L-Cit to confirm its usefulness for better adaptability in chickens under high temperature. Originality: Function of L-Cit and its metabolites to control heat stress has not yet been reported. Thus, I think a novel nutrient(s) will be discovered with its potential function to overcome heat stress..

KAKENHI Project (2015-2017): Mechanisms and functions of neuropeptides and amino acids to adapt heat-stress
2015.04～2017.03, 代表者：Vishwajit S. Chowdhury, Japan Society for the Promotion of Science (JSPS)
I wish to investigate the functional mechanism of some heat-stress bio-markers to determine their significance during heat-stress. Our recently identified heat-stress bio-markers are some brain neuropeptides and free amino acids in the brain and plasma. The goals of this project are a) to uncover whether the increased brain neuropeptides and altered free amino acids have some functional significance to adapt heat-stress, and b) find how supplementation of amino acids be helpful for better adaptation of organisms under warming environment..
