Gynandromorphic ticks are extremely rare, and often attract parasitologists’ attention. During our examination of tick specimens, an engorged gynandromorph of Hyalomma asiaticum was noticed. This is the first record of gynandromorphic ticks from China. In this study, several important morphological structures of normal and gynandromorphic H. asiaticum were analyzed. Comparing to the normal H. asiaticum, the gynandromorphic specimen was a typical bipartite protogynander. Its right side showed normal female characteristics, whereas the left side had normal male traits. Different from other gynandromorphic ticks containing 1 anus, this tick reported here had 2 complete anuses, and the anus of the male part had a single adanal plate.

Developing an efficient, environmentally friendly, and pollution-free catalyst with excellent visible light catalyticactivity is a promising strategy for dye wastewater treatment. Herein, the rod-like hollow BiOClxBr1x (x=1, 0.75, 0.5,0.25, 0), with an adjustable band gap, was successfully prepared using Bi-based metal-organic framework as template. The corresponding hollow assembly and introduction of Br imparted valuable structural advantages and intrinsic characteristicsfor improved photocatalytic activity. Significantly, the degradation efficiency of BiOCl0.5Br0.5 for the RhodamineB (RhB) solution reached 92% under visible light illumination for 90 min, which is considerably higher than that ofCAU-17-derived Bi2O3 and BiOCl. Overall, these findings shed fundamental insight on constructing novel photocatalystswith excellent visible light driven photocatalytic activity and offered a new method for treating dye wastewater.

Esophageal squamous cell carcinoma (ESCC) is one of the most life- and health-threatening malignant diseases worldwide, especially in China. Long noncoding RNAs (lncRNAs) have emerged as important regulators of tumorigenesis and tumor progression. However, the roles and mechanisms of lncRNAs in ESCC require further exploration. Here, in combination with a small interfering RNA (siRNA) library targeting specific lncRNAs, we performed MTS and Transwell assays to screen functional lncRNAs that were overexpressed in ESCC. TMPO-AS1 expression was significantly upregulated in ESCC tumor samples, with higher TMPOAS1 expression positively correlated with shorter overall survival times. In vitro and in vivo functional experiments revealed that TMPO-AS1 promotes the proliferation and metastasis of ESCC cells. Mechanistically, TMPO-AS1 bound to fused in sarcoma (FUS) and recruited p300 to the TMPO promoter, forming biomolecular condensates in situ to activate TMPO transcription in cis by increasing the acetylation of histone H3 lysine 27 (H3K27ac). Targeting TMPO-AS1 led to impaired ESCC tumor growth in a patient-derived xenograft (PDX) model. We found that TMPO-AS1 is required for cell proliferation and metastasis in ESCC by promoting the expression of TMPO, and both TMPO-AS1 and TMPO might be potential biomarkers and therapeutic targets in ESCC.

Sixty-one endophytic fungus strains with different colony morphologies were isolated from the leaves, stems and roots of Tephrosia purpurea with colonization rates of 66.95%, 37.50%, and 26.92%, respectively. Based on internal transcribed spacer sequence analysis, 61 isolates were classified into 16 genera belonging to 3 classes under the phylum Ascomycota. Of the 61 isolates, 6 (9.84%) exhibited antifungal activity against one or more indicator plant pathogenic fungi according to the dual culture test. Isolate TPL25 had the broadest antifungal spectrum of activity, and isolate TPL35 was active against 5 plant pathogenic fungi. Furthermore, culture filtrates of TPL25 and TPL35 exhibited greater than 80% growth inhibition against Sclerotinia sclerotiorum. We conclude that the endophytic fungal strains TPL25 and TPL35 are promising sources of bioactive compounds.

A series of 4′-N-substituted (aminomethyl)benzoate derivatives of scutellarein were designed and synthesized. Evaluation of their physiochemical properties showed that the designed target compounds 5a–e exhibit higher chemical stability and aqueous solubility than scutellarin and scutellarein. The permeability (Papp AP to BL ) of 5c–e in Caco-2 cells were 2.8, 8.1, and 12.6 times higher than that of scutellarin and 1.3, 4.1, and 6.0 times higher than that of scutellarein; especially, 5e had the highest P app AP to BL value (7.19 ± 0.31 × 10−6 cm/s) and the lowest ER (P app BL to AP /P app AP to BL ) value of 0.17. In vitro antioxidative evaluation results revealed that 5e could protect against H2O2 -induced PC12 cells’ oxidative damage by attenuating mitochondrial membrane potential loss and decreasing H2O2 -induced reactive oxygen species (ROS) production.

Drug-induced diabetes is widely reported inclinical conditions, and it is becoming a global issuebecause of its potential to increase the risk of severe cardiovascularcomplications. However, which drug mechanismsexert their diabetogenic effects and why the effectspresent significant inter-individual differences remain largelyunknown. Pharmacogenomics, which is the study ofhow genomic variation influences drug responses, providesan explanation for individual differences in drug-induceddiabetes. We highlight that pharmacogenomics can beinvolved in regulating the expression of genes in signalingpathways related to the pharmacokinetics or pharmacodynamicsof drugs or the pathogenesis of diabetes, contributingto the differences in drug-induced glucoseimpairment. The pharmacogenomics studies of the majordiabetogenic drugs are reviewed, including calcineurininhibitors, antipsychotics, hormones, and antihypertensivedrugs. We intend to elucidate the genetic basis of druginduceddiabetes and pave the way for the precise use ofthese drugs in the clinic.

Background: Fascin, an actin-bundling protein forming actin bundles including filopodia and stress fibers, is overexpressed in multiple human epithelial cancers including esophageal squamous cell carcinoma (ESCC). Previously we conducted a microarray experiment to analyze fascin knockdown by RNAi in ESCC. Method: In this study, the differentially expressed genes from mRNA expression profilomg of fascin knockdown were analyzed by multiple bioinformatics methods for a comprehensive understanding of the role of fascin. Results: Gene Ontology enrichment found terms associated with cytoskeleton organization, including cell adhesion, actin filament binding and actin cytoskeleton, which might be related to fascin function. Except GO categories, the differentially expressed genes were annotated by 45 functional categories from the Functional Annotation Chart of DAVID. Subpathway analysis showed thirty-nine pathways were disturbed by the differentially expressed genes, providing more detailed information than traditional pathway enrichment analysis. Two subpathways derivated from regulation of the actin cytoskeleton were shown. Promoter analysis results indicated distinguishing sequence patterns and transcription factors in response to the co-expression of downregulated or upregulated differentially expressed genes. MNB1A, c-ETS, GATA2 and Prrx2 potentially regulate the transcription of the downregulated gene set, while Arnt-Ahr, ZNF42, Ubx and TCF11-MafG might co-regulate the upregulated genes. Conclusions: This multiple bioinformatic analysis helps provide a comprehensive understanding of the roles of fascin after its knockdown in ESCC.

For the large scale services with high-dimensional QoS attributes and distributed environment, traditional service selection approaches are faced with unprecedented challenges in terms of efficiency and performance of QoS. To address these challenges, we propose a three-phase large scale Skyline service selection framework for service composition in clouds. This framework adopts distributed parallel Skyline computation with MapReduce to prune redundant candidate services, and employs parallel multi-objective optimization algorithm based on MapReduce to select Skyline services from the tremendous amount of Skyline services warehouse for composing single service into a set of more powerful Skyline composite services, then applies Top-k query processing technology or multiple attribute decision making support method to select k Skyline composite services from the set of Skyline composite services. Through theoretical analysis, the framework can efficiently solve the service selection problem with large scale services, high-dimensional QoS in cloud computing environment, and quickly generate better composite services with the global optimal QoS.

Although previous studies have demonstrated that BMP9 is highly capable of inducing osteogenic differentiation of mesenchymal stem cells, the molecular mechanism involved remains to be fully elucidated. In this study, we showed that BMP9 simultaneously promotes the activation of Smad1/5/8, p38 and ERK1/2 in C3H10T1/2 cells. Knockdown of Smad4 with RNA interference reduced nuclear translocation of Smad1/5/8, and disrupted BMP9-induced osteogenic differentiation. BMP9-induced osteogenic differentiation was blocked by p38 inhibitor SB203580, whereas enhanced by ERK1/2 inhibitor PD98059. SB203580 decreased BMP9-activated Smads singling, and yet PD98059 stimulated Smads singling in C3H10T1/2 cells. The effects of inhibitor were reproduced with adenovirus expressing siRNA targeted p38 and ERK1/2, respectively. Taken together, our findings revealed that Smads, p38 and ERK1/2 are involved in BMP9-induced osteogenic differentiation. Also, it is noteworthy that p38 and ERK1/2 may play opposing regulatory roles in mediating BMP9-induced osteogenic differentiation of C3H10T1/2 cells. [BMB reports 2012; 45(4): 247-252]
