Historical tectonism and climate oscillations can isolate and contract the geographical distributions of many plant species, and they are even known to trigger species divergence and ultimately speciation. Here, we estimated the nucleotide variation and speciation in three closely related Populus species, Populus tremuloides, P. tremula and P. davidiana, distributed in North America and Eurasia. We analysed the sequence variation in six single-copy nuclear loci and three chloroplast (cpDNA) fragments in 497 individuals sampled from...

Prostate cancer (PCa) is the second commonly diagnosed malignancy in men over the world. Although androgen deprivation therapy for advanced PCa patients has significantly improved their survival, the majority of these patients eventually develop castration-resistant prostate cancer (CRPC). Proscillaridin A (Pro A), a cardiac glycoside that is clinically used to treat various heart failure diseases, has been reported to have anticancer activity in several cancers. However, whether Pro A exerts an inhibitory effect on PCa...

In December 2019, Wuhan, China suffered a serious outbreak of a novel coronavirus infectious disease (COVID) caused by novel severe acute respiratory syndrome-related coronavirus (SARS-CoV 2). To quickly identify the pathogen, we designed and screened primer sets, and established a sensitive and specific qRT-PCR assay for SARS-CoV 2; the lower limit of detection (LOD) was 15 (95% CI: 9.8–21) copies per reaction. We combined this qRT-PCR assay with an automatic integration system for nucleic acid...

Burkholderia pseudomallei: which causes melioidosis with high mortality in humans, has become a global public health concern. Recently, infection-driven lipid droplet accumulation has been related to the progression of host-pathogen interactions, and its contribution to the pathogenesis of infectious disease has been investigated. Here, we demonstrated that B. pseudomallei infection actively induced a time-dependent increase in the number and size of lipid droplets in human lung epithelial cells and macrophages. We also found that lipid...

Mosquito-transmitted flaviviruses cause widespread disease across the world. To provide better molecular tools for drug screens and pathogenesis studies, we report a new approach to produce stable NanoLuc-tagged flaviviruses, including dengue virus serotypes 1-4, Japanese encephalitis virus, yellow fever virus, West Nile virus, and Zika virus. Since the reporter gene is often engineered at the capsid gene region, the capsid sequence must be duplicated to flank the reporter gene; such capsid duplication is essential for...

In our previous study, a gut microbiota-targeted dietary intervention with a high-fiber diet improved the immune status of both genetically obese (Prader-Willi Syndrome, PWS) and simple obese (SO) children. However, PWS children had higher inflammation levels than SO children throughout the trial, the gut microbiota of the two cohorts was similar. As some virulence factors (VFs) produced by the gut microbiota play a role in triggering host inflammation, this study compared the characteristics and changes...

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...

Bupleurum chinense DC. is a perennial herb plant belonging to the Umbelliferae family, genus Bupleurum, that is used as a traditional Chinese medicine. Coumarins are characteristic secondary metabolites of the Apiaceous family, which possess anti-inflammatory, anti-cancer and antiviral activities, among others. Few studies on the coumarin biosynthesis pathways in B. Chinese have been reported. In this study, we identified 89 differentially expressed genes belonging to 7 gene families involved in the synthesis of coumarins in...

Heat shock factor 1 (HSF1) has watershed significance in different tumors. However, the roles and driving forces for HSF1 in colorectal cancer (CRC) are poorly understood. Our study integrally analyzed the roles and driving forces for HSF1 in CRC by bioinformatics and experiments. The expression and prognostic characteristics of HSF1 were analyzed via UALCAN, GEPIA2, TISIDB, Prognoscan and HPA databases. Then, we analyzed the correlation between HSF1 expression and immune features via TIMER2 database. Subsequently,...

New whole-rock major and trace element, Sr-Nd isotopic, Zircon U-Pb, and Hf isotopic data for the Late Triassic intermediate-felsic intrusive rocks in the Liaodong Peninsula in the northeastern part of the North China Craton (NCC) were obtained in order to investigate their petrogenesis and provide insights into the Late Triassic tectonic evolution of the eastern segment of the NCC. The laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb ages indicate that they were emplaced...

Amino acids play crucial roles in the MTOR (mechanistic target of rapamycin kinase) complex 1 (MTORC1) pathway. However, the underlying mechanisms are not fully understood. Here, we establish a cell-free system to mimic the activation of MTORC1, by which we identify CANX (calnexin) as an essential regulator for leucine-stimulated MTORC1 pathway. CANX translocates to lysosomes after leucine deprivation, and its loss of function renders either the MTORC1 activity or the lysosomal translocation of MTOR insensitive...

ABSTRACT Introduction Applying the problem-based learning (PBL) method to the teaching of sports physiology. Objective This study explored the mechanism of the PBL method to improve the interest and learning effectiveness of students. Methods Twenty male students at the Physical Education College of Hubei Minzu University were randomly divided into a PBL group (10) and a traditional teaching method group (TTM). During the test, the subjects in the TTM group sat quietly listening to the...

Cancer-associated fibroblasts (CAFs) are considered one of the most critical stromal cells that interact with pancreatic ductal adenocarcinoma (PDAC) and promote tumor growth, metastasis, and treatment resistance. Previous studies illustrated macroautophagy/autophagy contributes to CAF activation during tumor progression. Here in our study, we found that autophagy deficiency in CAFs impedes CAF activation by inhibiting proline biosynthesis and collagen production. Furthermore, we uncovered that autophagy promotes proline biosynthesis through mitophagy-mediated regulation of NADK2 (NAD kinase 2,...
