Morphology and phylogeny of two new Thalassiosiroid taxa (Bacillariophyceae), with two marginal rimoportulae

Biaobiao Niu, Yaqiong Guo, Nina Lundholm & Yang Li
Thalassiosira and related taxa i.e. the taxa within Thalassiosirales are among the most abundant and widespread diatoms. The vast majority have one marginal rimoportula, but very few always have two. The knowledge on Thalassiosiroid taxa in Chinese waters is restricted, and to explore the diversity, monoclonal strains were established from southern Chinese coastal waters. Morphological data were based on light and scanning electron microscopy. The D1‒D3 region of the ribosomal large subunit (LSU) and the...

Plant elicitor peptide 1 fortifies root cell walls and triggers a systemic root-to-shoot immune signaling in Arabidopsis

Jie Zhang, Yuxi Li, Qixin Bao, Hongbo Wang & Shuguo Hou
Plant immunity is initiated by cell surface-localized receptors upon perception of pathogen-derived microbe or pathogen-associated molecular patterns (MAMPs/PAMPs), damage/danger-associated molecular patterns (DAMPs), and phytocytokines. Different patterns activate highly overlapping immune signaling at the early stage but divergent physiological responses at the late stage. Here, we indicate that plant elicitor peptide 1 (Pep1), a well-known DAMP, induces lignin and callose depositions, two types of late immune responses for strengthening the plant cell wall. Pep1-induced lignin and...

Difficulties translating antisense-mediated activation of Frataxin expression from cell culture to mice

Audrius Kilikevicius, Jun Wang, Xiulong Shen, Frank Rigo, Thahza P. Prakash, Marek Napierala & David R. Corey
Friedreich’s ataxia (FA) is an inherited neurodegenerative disorder caused by decreased expression of frataxin (FXN) protein. Previous studies have shown that antisense oligonucleotides (ASOs) and single-stranded silencing RNAs can be used to increase expression of frataxin in cultured patient-derived cells. In this study, we investigate the potential for oligonucleotides to increase frataxin expression in a mouse model for FA. After confirming successful in vivo delivery of oligonucleotides using a benchmark gapmer targeting the nuclear noncoding...

Hainan He, Junling Wang, Xingmei Mou, Xin Liu, Qiao Li, Mingyue Zhong, Bingbing Luo, Zhisheng Yu, Jingjing Zhang, Tian Xu, Chengli Dou, Danya Wu, Wei Qing, Linhui Wu, Kai Zhou, Zhengang Fan, Tingting Wang, Taotao Hu, Xia Zhang, Jilong Zhou & Yi-Liang Miao
Macroautophagy/autophagy is a cellular and energy homeostatic mechanism that contributes to maintain the number of primordial follicles, germ cell survival, and anti-ovarian aging. However, it remains unknown whether autophagy in granulosa cells affects oocyte maturation. Here, we show a clear tendency of reduced autophagy level in human granulosa cells from women of advanced maternal age, implying a potential negative correlation between autophagy levels and oocyte quality. We therefore established a co-culture system and show that...

Jinjin Zhang, Haixia Wang, Hongbin Chen, Hongbo Li, Pan Xu, Bo Liu, Qian Zhang, Changjun Lv & Xiaodong Song
Idiopathic pulmonary fibrosis (IPF) is characterized by lung scarring and has no effective treatment. Fibroblast-to-myofibroblast differentiation and myofibroblast proliferation and migration are major clinical manifestations of this disease; hence, blocking these processes is a practical treatment strategy. Here, highly upregulated LINC00941/lncIAPF was found to accelerate pulmonary fibrosis by promoting fibroblast-to-myofibroblast differentiation and myofibroblast proliferation and migration. Assay for transposase-accessible chromatin using sequencing and chromatin immunoprecipitation experiments elucidated that histone 3 lysine 27 acetylation (H3K27ac) activated...

Offshore Island Connection Line: A new perspective of coastal urban development boundary simulation and multi-scenario prediction

Fei He, Jun Yang, Yuqing Zhang, Dongqi Sun, Li Wang, Xiangming Xiao & Jianhong Xia
The urban development boundary (UDB) is a core issue in territorial spatial planning and remains a research focus in urban development. However, in the past, land use simulations of coastal cities have had some limitations. For example, new urban land outside the research boundary could not be effectively simulated, resulting in a large gap between the simulation results and reality. In this study, an artificial neural network (ANN) cellular automata (CA) model based on a...

Peili Hou, Xuefeng Wang, Hongmei Wang, Tiecheng Wang, Zhangping Yu, Chunqing Xu, Yudong Zhao, Wenqi Wang, Yong Zhao, Fengyun Chu, Huasong Chang, Hongchao Zhu, Jiahui Lu, Fuzhen Zhang, Xue Liang, Xingyu Li, Song Wang, Yuwei Gao & Hongbin He
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is closely related to various cellular aspects associated with autophagy. However, how SARS-CoV-2 mediates the subversion of the macroautophagy/autophagy pathway remains largely unclear. In this study, we demonstrate that overexpression of the SARS-CoV-2 ORF7a protein activates LC3-II and leads to the accumulation of autophagosomes in multiple cell lines, while knockdown of the viral ORF7a gene via shRNAs targeting ORF7a sgRNA during SARS-CoV-2 infection decreased autophagy levels. Mechanistically,...
