Triggering receptor expressed on myeloid cells (TREM) like transcript-1 (TLT-1) reveals platelet activation in preeclampsia

Linyan He, Yawen Zhang, Chunqi Hou, Ziling Zhu, Qi He, Qin Huang & Shundong Ji
Triggering receptor expressed on myeloid cells (TREM) like transcript-1 (TLT-1) is a membrane protein receptor found in α-granules of megakaryocytes and platelets. Upon platelet activation TLT-1 is rapidly relocated to the surface of platelets. In plasma, a soluble form of TLT-1 (sTLT-1) is present. Plasma levels of sTLT-1 are significantly elevated in thrombotic diseases. In the present study, we investigated to whether TLT-1 reflects platelet activation in pregnant women with preeclampsia. We studied 30 preeclamptic...

Upstream open reading frames mediate autophagy-related protein translation

Ying Yang, Damian Gatica Mizala, Xu Liu, Runliu Wu, Rui Kang, Daolin Tang & Daniel J. Klionsky
Macroautophagy/autophagy, a highly conserved catabolic pathway that maintains proper cellular homeostasis is stringently regulated by numerous autophagy-related (Atg) proteins. Many studies have investigated autophagy regulation at the transcriptional level; however, relatively little is known about translational control. Here, we report the upstream open reading frames (uORFs)-mediated translational control of multiple Atg proteins in Saccharomyces cerevisiae and in human cells. The translation of several essential autophagy regulators in yeast, including Atg13, is suppressed by canonical uORFs...

Stachydrine is effective and selective against blast phase chronic myeloid leukaemia through inhibition of multiple receptor tyrosine kinases

Ruixin Gu, Wei Zhang & Dandan Xu
Resistance to BCR-ABL tyrosine kinase inhibitor (TKI) is the cause of treatment failure in blast phase chronic myeloid leukaemia (BP-CML). Agents that act synergistically with BCR-ABL TKI are required to improve response. This work investigated the effects of stachydrine in CML. CML cells were treated with control or stachydrine at 20, 40 and 80 µM. Proliferation and apoptosis were examined after 72 h treatment. Combination studies were performed in four groups: control, TKI, stachydrine and...

Customizable process design for collaborative geographic analysis

Zaiyang Ma, Min Chen, Zhong Zheng, Songshan Yue, Zhiyi Zhu, Beichen Zhang, Jin Wang, Fengyuan Zhang, Yongning Wen & Guonian Lü
Collaborative geographic analysis can lead to better outcomes but requires complicated interactions among participants, support resources and analytic tools. A process expression with explicit structure and content can help coordinate and guide these interactions. For different geographic problems, the structure and content of collaborative geographic analysis are generally distinct. Since the process structure embodies the pathway of problem-solving and the process content contains the information flow and internal interactions, both the structure and the content...

Wenwen Liu, Min Chen, Chao Liu, Liying Wang, Huafang Wei, Ruidan Zhang, Zhengxing Ren, Yinghong Chen, Mengcheng Luo, Jianguo Zhao, Hongwei Jiang, Fei Gao & Wei Li
Primary ovarian insufficiency (POI), also known as premature ovarian failure, is an ovarian defect in humans characterized by the premature depletion of ovarian follicles before the age of 40. However, the mechanisms underlying POI remain largely unknown. Here, we show that knockout of Epg5 (ectopic P-granules autophagy protein 5 homolog (C. elegans)) results in subfertility in female mice, which exhibit a POI-like phenotype. Single-cell RNA sequencing analysis revealed that the knockout of Epg5 affected the...

Pressure-induced enhancement and retainability of optoelectronic properties of NiPS3

Sixue Fang, Quanjun Li, Zonglun Li, Qing Dong, Xiaoling Jing, Chenyi Li, Haiyan Li, Bo Liu, Ran Liu & Bingbing Liu
Here, we report significant pressure-modulate optoelectronic properties of NiPS3. Upon compression, NiPS3 exhibited a photocurrent increase of five orders of magnitude over the initial value. Interestingly, when NiPS3 was finally decompressed to ambient conditions, the photocurrent could maintain a two-order-of-magnitude enhancement. In addition, the spectral response range was extended to the near-infrared spectral range (up to 1650 nm) under high pressure. Raman and XRD measurements and theoretical calculations revealed significant enhancement in both interlayer and...

Comparative analysis of mitochondrial genomes of maize CMS-S subtypes provides new insights into male sterility stability

Senlin Xiao, Jingfeng Xing, Tiange Nie, Aiguo Su, Ruyang Zhang, Yanxin Zhao, Wei Song & Jiuran Zhao
Abstract Background Cytoplasmic male sterility (CMS) is a trait of economic importance in the production of hybrid seeds. In CMS-S maize, exerted anthers appear frequently in florets of field-grown female populations where only complete male-sterile plants were expected. It has been reported that these reversions are associated with the loss of sterility-conferring regions or other rearrangements in the mitochondrial genome. However, the relationship between mitochondrial function and sterility stability is largely unknown. Results In this...
