TC10 as an essential molecule in axon regeneration through membrane supply and microtubule stabilization

Neural Regeneration Research 2022年第1期17卷 87-88页

作者： takeshi Nakamura Shingo Koinuma Division of Cell Signaling Research Institute for Biomedical SciencesTokyo University of ScienceNodaJapan

Mammalian central nervous system(CNS)neurons lose axon regenerative ability as they *** failure to regenerate shows a clear contrast to a remarkable potential of axon growth during embryonic development and after an injury in the peripheral nervous system(PNS)(Hilton and Bradke,2017).The absence of regeneration in the mature CNS neurons is caused by an inhibitory influence of the environment of the injured axons and the deficit of intrinsic factors that enable regeneration in the PNS(He and Jin,2016).

Molecular basis of scavenging effect of zonisamide on hydroxyl radical <i>in vitro</i>

引用

Journal of Biophysical Chemistry 2012年第3期3卷 256-258页

作者： Ken-ichi Tanaka takeshi Nanba Tomoyuki Furubayashi Yasuko noda Luther James Willmore Akitane Mori Department of Bacteriology Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Shikatacho Japan Department of Brain Science Okayama University Graduate School of Medicine Dentistry and Pharmaceutical Sciences Shikatacho Japan Department of Clinical Pharmacy Shujitsu University School of Pharmacy Nishigawara Japan Department of Neurology Saint Louis University School of Medicine St. Louis USA

Zonisamide (ZNS), a commonly used anticonvulsant, scavenged hydroxyl radicals at a clinically relevant concentration. Reactants of ZNS with hydrogen peroxide and with hydrogen peroxide plus UV irradiation, yielding hydroxyl radicals, were analyzed by the LC/MS technique. Many small fragments were found in the both reactions, suggesting that ZNS was decomposed not only by hydroxyl radicals but also by hydrogen peroxide. Furthermore, mass-fragment-grams showed that m/z: 213 (ZNS itself) was decreased markedly and m/z: 118 (may be a decomposed product by ring cleavage of ZNS) was detected specifically by treatment with hydroxyl radical. These data suggested that ZNS may react directly with free radicals.

BACKGROUND Tumor size impacts the technical difficulty and histological curability of colorectal endoscopic submucosal dissection(ESD);however,the preoperative evaluation of tumor size is often different from histological *** influential factors on failure to obtain an accurate tumor size evaluation could help prepare optimal conditions for safer and more reliable *** This was a retrospective study conducted at a single institution.A total of 377 lesions removed by colorectal ESD at our hospital between April 2018 and March 2022 were *** first assessed the difference in size with an absolute per-centage of the scaling ***,we compared the clinicopatho-logical characteristics of the correct scaling group(>-33%and33%),which was further subdivided into the underscaling group(-33%or less of the discrepancy)and overscaling group(33%or more of the discrepancy),*** secondary outcome measures,parameters on size estimation were compared between the underscaling and correct scaling groups,as well as between the overscaling and correct scaling ***,multivariate analysis was performed in terms of the following relevant parameters on size estimation:Pathological size,location,and possible influential factors(P<0.1)in the univariate *** The mean of absolute percentage in the scaling discordance was 21%,and 91 lesions were considered to be incorrectly estimated in *** incorrect scaling was significantly remarkable in larger lesions(40 mm vs 28 mm;P<0.001)and less experience(P<0.001),and these two factors were influential on the underscaling(75 lesions;P<0.001).Conversely,compared with the correct scaling group,16 lesions in the overscaling group were significantly small(20 mm vs 28 mm;P<0.001),and the small lesion size was influential on the overscaling(P=0.002).CONCLUSION Lesions indicated for colorectal ESD tended to be underestimate

SD3, an Arabidopsis thaliana Homolog of TIM21, Affects Intracellular ATP Levels and Seedling Development

It is poorly understood how plants control their growth by cell division, elongation, and differentiation. We have characterized a seedling-lethal mutant segregation distortion 3 （sd3） that showed a very dwarf phenotype when grown in the light and, in the dark, had short hypocotyls with reduced ploidy levels. The corresponding gene of SD3 encodes a protein with high similarity to yeast translocase on the inner mitochondrial membrane 21 （TIM21）, which is a component of the TIM23 complex. Indeed, SD3 protein fused to GFP localized in the mitochondria. SD3 overexpression increased cotyledon size in the light and hypocotyl thickness in the dark. The expression of genes for several subunits of the respiratory-chain complexes III and IV was up-regulated in SD3-overexpressing plants. Furthermore, these plants showed high levels of ATP whereas those of sd3 were low. These results suggested that SD3 induced an increase in cell size by raising the expression of the respiratory-chain subunit genes and hence increased the intracellular ATP levels, We propose that intracellular ATP levels regulated by mitochondria control plant organ size.
