The Genetic Dissection of a Short-Term Response to Low CO_(2) Supports the Possibility for Peroxide-mediated Decarboxylation of Photorespiratory Intermediates in the Peroxisome

Dear Editor, Photorespiration reduces plant carbon assimilation by an estimated 25%-50% of net CO2 assimilation in typical C3 plants （Roussel and Igamberdiev, 2011）. It results from the oxygenase activity of Rubisco giving rise to phosphogly- colate. Subsequent photorespiratory metabolism involves decarboxylation of glycine in the mitochondrion and reduc- tion of hydroxypyruvate, usually assumed to occur in the peroxisome. Recent research in Arabidopsis has highlighted possible alternative sites of hydroxypyruvate reductase （HPR） activity （Figure 1A）. In addition to the accepted reduction by peroxisomal HPR1, Timm et al. （2008） identified cytosolic HPR2 and a putative chloroplast HPR3 （Timm et al., 2011）. For HPR2 or HPR3 to function in photorespiration, hydroxypyru- vate would first need to pass from the peroxisome into the cytosol. Another potential fate for hydroxypyruvate is its non-enzymic （NE） decarboxylation by reaction with hydrogen peroxide as previously suggested by experiments performed on isolated peroxisomes （Walton and Butt, 1981）.

Cellular arsenic transport pathways in mammals

Journal of Environmental Sciences 2016年第11期28卷 38-58页

Natural contamination of drinking water with arsenic results in the exposure of millions of people world-wide to unacceptable levels of this metalloid. This is a serious global health problem because arsenic is a Group 1（proven） human carcinogen and chronic exposure is known to cause skin, lung, and bladder tumors. Furthermore, arsenic exposure can result in a myriad of other adverse health effects including diseases of the cardiovascular,respiratory, neurological, reproductive, and endocrine systems. In addition to chronic environmental exposure to arsenic, arsenic trioxide is approved for the clinical treatment of acute promyelocytic leukemia, and is in clinical trials for other hematological malignancies as well as solid tumors. Considerable inter-individual variability in susceptibility to arsenic-induced disease and toxicity exists, and the reasons for such differences are incompletely understood. Transport pathways that influence the cellular uptake and export of arsenic contribute to regulating its cellular, tissue, and ultimately body levels. In the current review, membrane proteins（including phosphate transporters, aquaglyceroporin channels, solute carrier proteins, and ATP-binding cassette transporters） shown experimentally to contribute to the passage of inorganic, methylated, and/or glutathionylated arsenic species across cellular membranes are discussed. Furthermore, what is known about arsenic transporters in organs involved in absorption, distribution, and metabolism and how transport pathways contribute to arsenic elimination are described.

Purpose The purpose of the present study was to examine the day-to-day consistency and inter-subject variability of com-posite and individual,neuromuscular and torque patterns of responses as a result of a fatiguing bout of maximal,bilateral,isokinetic leg extension muscle *** Ten men (mean ± SD =21.6 ± 2.5 years) completed two testing visits consisting of pretest and posttest maximal voluntary isometric contractions (mVIC) as well as 25 maximal,bilateral,isokinetic (180°/s),leg extension muscle *** (EmG) and mechanomyographic (mmG) signals were collected from the vastus lateralis and normalized to the *** fatigability was defined as the percent decline in torque between the average of repetitions 1,2,and 3 and repetitions 23,24,and *** regression was used to examine the individual and composite relation-ships between EmG amplitude (AmP),EmG mean power frequency (mPF),mmG AmP,mmG mPF,and torque versus *** There was no significant difference (d =0.80;P =0.17) in the performance fatigability between Day 1 (19.3% ± 7.1%)and Day 2 (26.9% ± 11.3%).Polynomial regression indicated substantial inter-subject variability,but high day-to-day *** The composite EmG AmP,mmG AmP,and mmG mPF patterns of responses demonstrated consistency across *** composite EmG mPF patterns of responses,however,were not consistent between Day 1 and Day *** addition,based on the high inter-subject variability,future studies should present both composite patterns of neuromuscular responses and the patterns of responses on a subject-by-subject basis to make inferences regarding fatigue-induced changes in motor unit activation strategies.
