Mitochondrial TrxR2 regulates metabolism and protects from metabolic disease through enhanced TCA and ETC functionCommunications Biology - Tập 5 Số 1
E. Sandra Chocrón, Kennedy S. Mdaki, Nisi Jiang, Jodie Cropper, Andrew M. Pickering
AbstractMitochondrial dysfunction is a key driver of diabetes and other metabolic diseases. Mitochondrial redox state is highly impactful to metabolic function but the mechanism driving this is unclear. We generated a transgenic mouse which overexpressed the redox enzyme Thioredoxin Reductase 2 (TrxR2), the rate limiting enzyme in the mitochondrial thioredoxin syst...... hiện toàn bộ
Rab5-mediated endosome formation is regulated at the trans-Golgi networkCommunications Biology - Tập 2 Số 1
Makoto Nagano, Junko Y. Toshima, Daria E. Siekhaus, Jiro Toshima
AbstractEarly endosomes, also called sorting endosomes, are known to mature into late endosomes via the Rab5-mediated endolysosomal trafficking pathway. Thus, early endosome existence is thought to be maintained by the continual fusion of transport vesicles from the plasma membrane and the trans-Golgi network (TGN). Here we show instead t...... hiện toàn bộ
The feather degradation mechanisms of a new Streptomyces sp. isolate SCUT-3Communications Biology - Tập 3 Số 1
Zhiwei Li, Shuang Liang, Ke Ye, Jun‐Jin Deng, Ming-Shu Zhang, De‐Lin Lu, Jiansheng Zhang, Xiao‐Chun Luo
AbstractFeather waste is the highest protein-containing resource in nature and is poorly reused. Bioconversion is widely accepted as a low-cost and environmentally benign process, but limited by the availability of safe and highly efficient feather degrading bacteria (FDB) for its industrial-scale fermentation. Excessive focuses on keratinase and limited knowledge ...... hiện toàn bộ
Cell-type specific pallial circuits shape categorical tuning responses in the crow telencephalonCommunications Biology - Tập 5 Số 1
Helen M. Ditz, Julia Fechner, Andreas Nieder
AbstractThe nidopallium caudolaterale (NCL), an integration centre in the telencephalon of birds, plays a crucial role in representing and maintaining abstract categories and concepts. However, the computational principles allowing pallial microcircuits consisting of excitatory and inhibitory neurons to shape the tuning to abstract categories remain elusive. Here w...... hiện toàn bộ
Regulation of RNA editing by RNA-binding proteins in human cellsCommunications Biology - Tập 2 Số 1
Giovanni Quinones-Valdez, Stephen Tran, Hyun-Ik Jun, Jae Hoon Bahn, Ei-Wen Yang, Lijun Zhan, Anneke Brümmer, Xintao Wei, Eric L. Van Nostrand, Gabriel A. Pratt, G Yeo, Jacques Ravel, Xinshu Xiao
AbstractAdenosine-to-inosine (A-to-I) editing, mediated by the ADAR enzymes, diversifies the transcriptome by altering RNA sequences. Recent studies reported global changes in RNA editing in disease and development. Such widespread editing variations necessitate an improved understanding of the regulatory mechanisms of RNA editing. Here, we study the roles of >2...... hiện toàn bộ
Structural determinants of dynamic fluctuations between segregation and integration on the human connectomeCommunications Biology - Tập 3 Số 1
Makoto Fukushima, Olaf Sporns
AbstractWhile segregation and integration of neural information in the neocortex are thought to be important for human behavior and cognition, the neural substrates enabling their dynamic fluctuations remain elusive. To tackle this problem, we aim to identify specific network features of the connectome that are responsible for the emergence of dynamic fluctuations ...... hiện toàn bộ
Transferrin receptor 1 is a cellular receptor for human heme-albuminCommunications Biology - Tập 3 Số 1

AbstractIron is essential for living cells. Uptake of iron-loaded transferrin by the transferrin receptor 1 (CD71, TFR) is a major but not sufficient mechanism and an alternative iron-loaded ligand for CD71 has been assumed. Here, we demonstrate that CD71 utilizes heme-albumin as cargo to transport iron into human cells. Binding and endocytosis of heme-albumin via ...... hiện toàn bộ
Two-tone distortion in reticular lamina vibration of the living cochleaCommunications Biology - Tập 3 Số 1
Tianying Ren, Wenxuan He
AbstractIt has been demonstrated that isolated auditory sensory cells, outer hair cells, can generate distortion products at low frequencies. It remains unknown, however, whether or not motile outer hair cells are able to generate two-tone distortion at high frequencies in living cochleae under the mechanical loads caused by surounding tissues and fluids. By measur...... hiện toàn bộ
