Comparative transcriptome analysis revealed the cooperative regulation of sucrose and IAA on adventitious root formation in lotus (Nelumbo nucifera Gaertn).

BACKGROUND: In China, lotus is an important cultivated crop with multiple applications in ornaments, food, and environmental purification. Adventitious roots (ARs), a secondary root is necessary for the uptake of nutrition and water as the lotus principle root is underdeveloped. Therefore, AR formation in seedlings is very important for lotus breeding due to its effect on plant early growth. As lotus ARs formation was significantly affected by sucrose treatment, we analyzed the expression of genes and miRNAs upon treatment with differential concentrations of sucrose, and a crosstalk between sucrose and IAA was also identified. RESULTS: Notably, 20 mg/L sucrose promoted the ARs development, whereas 60 mg/L sucrose inhibited the formation of ARs. To investigate the regulatory pathway during ARs formation, the expression of genes and miRNAs was evaluated by high-throughput tag-sequencing. We observed that the expression of 5438, 5184, and 5345 genes was enhanced in the GL20/CK0, GL60/CK0, and CK1/CK0 libraries, respectively. Further, the expression of 73, 78, and 71 miRNAs was upregulated in the ZT20/MCK0, ZT60/MCK0, and MCK1/MCK0 libraries, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed that most of the differentially expressed genes and miRNAs in the GL20/GL60 and ZT20/ZT60 libraries were involved in signal transduction. A large number of these genes (29) and miRNAs (53) were associated with plant hormone metabolism. We observed an association between five miRNAs (miR160, miR156a-5p, miR397-5p_1, miR396a and miR167d) and nine genes (auxin response factor, protein brassinosteroid insensitive 1, laccase, and peroxidase 27) in the ZT20/ ZT60 libraries during ARs formation. Quantitative polymerase chain reaction (qRT-PCR) was used to validate the high-throughput tag-sequencing data. CONCLUSIONS: We found that the expression of many critical genes involved in IAA synthesis and IAA transport was changed after treatment with various concentration of sucrose. Based on the change of these genes expression, IAA and sucrose content, we concluded that sucrose and IAA cooperatively regulated ARs formation. Sucrose affected ARs formation by improving IAA content at induction stage, and increased sucrose content might be also required for ARs development according to the changes tendency after application of exogenous IAA.

Urine Proteome of COVID-19 Patients

The atypical pneumonia (COVID-19) caused by SARS-CoV-2 is an ongoing pandemic and a serious threat to global public health. The COVID-19 patients with severe symptoms account for a majority of mortality of this disease. However, early detection and effective prediction of patients with mild to severe symptoms remains challenging. In this study, we performed proteomic profiling of urine samples from 32 healthy control individuals and 6 COVID-19 positive patients (3 mild and 3 severe). We found that urine proteome samples from the mild and severe COVID-19 patients with comorbidities can be clearly differentiated from healthy proteome samples based on the clustering analysis. Multiple pathways have been compromised after the COVID-19 infection, including the dysregulation of immune response, complement activation, platelet degranulation, lipoprotein metabolic process and response to hypoxia. We further validated our finding by directly comparing the same patients urine proteome after recovery. This study demonstrates the COVID-19 pathophysiology related molecular alterations could be detected in the urine and the potential application of urinary proteome in auxiliary diagnosis, severity determination and therapy development of COVID-19.

Transcriptome analysis of miRNAs expression reveals novel insights into adventitious root formation in lotus (Nelumbo nucifera Gaertn.).

MicroRNA (miRNA)-regulated gene expression plays an important role in various plant metabolic processes. Although adventitious roots are critical to plant growth in lotus, the role of miRNA in AR formation remains unclear. Expression profiling of miRNAs was carried out during three different developmental stages of ARs in lotus: no induction of AR stage, initial stage of ARs, and maximum number of ARs. These data are referenced with the whole lotus genome as already identified through high-throughput tag-sequencing. 1.3 × 107 tags were achieved, of which 11,035,798, 11,436,062, and 12,542,392 clean tags were obtained from each stage, respectively. miRNA analysis revealed that miRNAs were less than 10% among all small RNAs. In total, 310 miRNAs (240 up-regulated and 70 down-regulated miRNAs) exhibited expression changes from the no induction stage to the initial stage. Moreover, expression of 140 miRNAs was increased and that of 123 miRNAs was decreased between the initial and maximum AR stages, mostly by ~ - 4-4-fold. miRNAs involved in metabolic pathways differed between the initial stage/no induction stage and the maximum number stage/initial stage. Several miRNAs in the initial stage/no induction stage were related to plant hormone metabolism and pyruvate and MAPK pathways, while major miRNAs in the maximum number stage/initial stage were involved in carbohydrate metabolism. All differentially expressed miRNAs associated with AR formation from the initial stage to maximum stage were also analyzed. The expression of 16 miRNAs was determined using qRT-PCR. This work provides a general insight into miRNA regulation during AR formation in lotus.

Ablation of gut microbiota alleviates obesity-induced hepatic steatosis and glucose intolerance by modulating bile acid metabolism in hamsters

Since metabolic process differs between humans and mice, studies were performed in hamsters, which are generally considered to be a more appropriate animal model for studies of obesity-related metabolic disorders. The modulation of gut microbiota, bile acids and the farnesoid X receptor (FXR) axis is correlated with obesity-induced insulin resistance and hepatic steatosis in mice. However, the interactions among the gut microbiota, bile acids and FXR in metabolic disorders remained largely unexplored in hamsters. In the current study, hamsters fed a 60% high-fat diet (HFD) were administered vehicle or an antibiotic cocktail by gavage twice a week for four weeks. Antibiotic treatment alleviated HFD-induced glucose intolerance, hepatic steatosis and inflammation accompanied with decreased hepatic lipogenesis and elevated thermogenesis in subcutaneous white adipose tissue (sWAT). In the livers of antibiotic-treated hamsters, cytochrome P450 family 7 subfamily B member 1 (CYP7B1) in the alternative bile acid synthesis pathway was upregulated, contributing to a more hydrophilic bile acid profile with increased tauro--muricholic acid (TMCA). The intestinal FXR signaling was suppressed but remained unchanged in the liver. This study is of potential translational significance in determining the role of gut microbiota-mediated bile acid metabolism in modulating diet-induced glucose intolerance and hepatic steatosis in the hamster.

Effects of eye acupuncture therapy on neurological function and brain-derived neurotrophic factor expression in a rat model of cerebral ischemia/reperfusion injury / 中国组织工程研究

BACKGROUND: Eye acupuncture therapy is a technique used to adjust qi-blood circulation, relax muscles and tendons, and activate col aterals by acupuncture at the acupoints around the eye bal s and in the orbital border. This therapy has been widely used in the clinic because it exhibits remarkable therapeutic effects on many ischemic cerebrovascular diseases. However, the precise mechanism behind this therapy remains poorly understood. Neurotrophic factors are a protein family including neurotrophic factors and brain-derived neurotrophic factors that can regulate neuronal survival, development and functioning. OBJECTIVE: To investigate the effects of eye acupuncture therapy on neurological function and nerve growth factor and brain-derived neurotrophic factor expression in the brain tissue of rat models of cerebral ischemia/reperfusion injury. METHODS: Fifty-four male Sprague-Dawley rats were randomly divided into three groups with 18 rats per group: sham-operated, model and eye acupuncture therapy groups. Rat models of middle cerebral artery occlusion were established by the intraluminal suture method in the model and eye acupuncture therapy groups. Eye acupuncture was performed at the fol owing acupoints liver area, upper-jiao area, lower-jiao area and kidney area located at the internal orbital margin at 2 hours after cerebral ischemia/reperfusion injury. Rat neurological function was evaluated at 3, 7, and 14 days after injury. Nerve growth factor and brain-derived neurotrophic factor expression in the rat brain tissue was detected using immunohistochemical staining method at 1 and 2 weeks after treatment. Cerebral infarct size was determined using TTC staining at 2 weeks after treatment. RESULTS AND CONCLUSION: (1) At 1 and 2 weeks after injury, nerve growth factor and brain-derived neurotrophic factor expression was significantly greater in the eye acupuncture therapy group than in the model group (P < 0.05), but nerve growth factor and brain-derived neurotrophic factor expression in the eye acupuncture therapy group was decreased at 2 weeks after injury compared to that at 1 week after injury. (2) At 7 and 14 days after treatment, neurological function scores in the eye acupuncture therapy group were significantly lowered, and there was significant difference between eye acupuncture therapy and model groups (P < 0.05), but they were significantly higher than those in the sham-operated group (P< 0.05). (3) At 2 weeks after treatment, cerebral infarct size was significantly greater in the eye acupuncture therapy and model groups than in the sham-operated group (P < 0.01), and it was significantly smal er in the eye acupuncture therapy group than in the model group (P < 0.05). (4)These results indicate that eye acupuncture therapy shows neuroprotective effects on ischemic cerebral injury by increasing nerve growth factor and brain-derived neurotrophic factor expression, improving neurological function, and reducing cerebral infarct size.
