The outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratorysyndrome coronavirus 2 has rapidly spread globally. Cancer patients are at a higher risk ofbeing infected with the coronavirus and are more likely to develop severe complications, ascompared to the general population. The increasing spread of COVID-19 presents challengesfor the clinical care of patients with gynecological malignancies. Concerted efforts should beput into managing gynecological malignancies in an orderly manner by strictly implementingthe measures that are specifically developed for controlling the spread of COVID-19. We havedrafted Recommendations on Management of Gynecological Malignancies during the COVID-19 Pandemicbased on our experience on controlling COVID-19 pandemic in China. We recommendthat patients with gynecological malignancies should be managed in hierarchical andindividualized manners in combination with local conditions related to COVID-19. Medicalcare decision should be balanced between controlling COVID-19 pandemic spread and timelydiagnosis and treatment for gynecologic oncology patients.

The purpose of this study was to evaluate the association of expression of ${\alpha}5{\beta}1$-integrin with clinicopathologic features and prognosis in cervical cancer. Levels of ${\alpha}5{\beta}1$-integrin in normal cervical mucosa and cervical cancer tissue were detected with immunohistochemistry. Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance. ${\alpha}5{\beta}1$-integrin expression was detected in 84.6% (143/169) cervical cancer samples, significantly different from that in normal cervical mucosa (P < 0.05). Positive expression rates of ${\alpha}5{\beta}1$-integrin in patients with poor histologic differentiation, lymph node metastasis, and recurrence were elevated. Using Kaplan-Meier analysis, a comparison of survival curves of low versus high expression of ${\alpha}5{\beta}1$-integrin revealed a highly significant difference in human cervical cancer cases (P < 0.05), suggesting that overexpression of ${\alpha}5{\beta}1$-integrin is associated with a worse prognosis.The ${\alpha}5{\beta}1$-integrin promotes angiogenesis and associates with lymph node metastasis, vascular invasion and poor prognosis of cervical cancer. The current study indicated that ${\alpha}5{\beta}1$-integrin may be an independent prognostic factor for cervical cancer patients.

We report the annotation and analysis of the draft genome sequence of Brassica rapa accession Chiifu-401-42, a Chinese cabbage. We modeled 41,174 protein coding genes in the B. rapa genome, which has undergone genome triplication. We used Arabidopsis thaliana as an outgroup for investigating the consequences of genome triplication, such as structural and functional evolution. The extent of gene loss (fractionation) among triplicated genome segments varies, with one of the three copies consistently retaining a disproportionately large fraction of the genes expected to have been present in its ancestor. Variation in the number of members of gene families present in the genome may contribute to the remarkable morphological plasticity of Brassica species. The B. rapa genome sequence provides an important resource for studying the evolution of polyploid genomes and underpins the genetic improvement of Brassica oil and vegetable crops.

The micellization and the molecular interaction behaviors for two ternary mixtures constituted by anamphoteric sodium 3-(n-dodecyl ethylenediamino)-2-hydroxypropyl sulfonate (C12AS), an anionicsodium dodecylbenzene sulfonate (SDBS) and a nonionic octylphenol polyoxyethylated ether with thenumber (n) of oxyethylene glycol ethers OP-n (n = 10 or 7) in aqueous solution were investigated usingthe tensiometry and the effect of hydrophilicity on them was also discussed. In the framework of pseudophaseseparation model and based on the regular solution theory, the related micellization parametersincluding the mixed critical micelle concentration (cmc) values in the ideal and real cases, the activitycoefficients and the compositions in mixed micelle, etc. and thermodynamic parameters were estimatedby the Clint’s model and the Rubingh’ model. The mixed cmc value is dependent on the composition inaqueous solution and influenced by the hydrophilicity of nonionic surfactant. With increasing the nonionicin ternary mixture, the mixed cmc value is initially decreased and then slightly rise. An increasingin the hydrophilicity of nonionic will make the minimum value of mixed cmc be increased from1.299 mM to 1.705 mM. The resulting phenomena can be explained reasonably by the electrostatic effect,the steric hindrance, the hydrogen bonding, etc. Thermodynamic data indicate that the contribution ofentropy or enthalpy plays a vital role on the spontaneous process of micellization and the share ofentropy or enthalpy in free energy change is dependent largely on the amount of nonionic surfactantand the hydrophilicity. In ternary mixtures of C12AS/SDBS/OP-10, an increase in an amount of OP-10 willinduce the change from the enthalpy-driven micellization process to the entropically favorable process. Once an abundant amount of OP-7 is added, while, the enthalpy will make a main contribution on themicellization process, which can be described by the drop in the share of entropy at the composition(0.6970/0.0000/0.3030) of ternary mixture from 0.6478 to 0.4901. These findings will help with understandingthe molecular interaction behavior for the ternary surfactant mixture and the effect of the additionof nonionic surfactant and its hydrophilicity.

Nogo protein, encoded by gene reticulon-4 (RTN4), includes three major isoforms by different splicing, named Nogo-A Nogo-B and Nogo-C. Nogo proteins play an important role in the apoptosis of cells, especially in tumor cells. RTN4 single nucleotide polymorphisms (SNPs) can influence the efficiency of transcription and translation thus being related with an individual's predisposition to cancer. The CAA insertion/deletion polymorphism (rs34917480) within RTN4 3'-UTR has been reported to be associated with many cancer types. In order to investigate the relationship between this polymorphism and susceptibility to non-small cell lung cancer (NSCLC) in the Chinese population, we conducted the present case-control study including 411 NSCLC patients and 471 unrelated healthy controls. The genotype distributions were significantly different between cases and controls (p=0.014). We found that the del allele could significantly increase NSCLC risk (ins/ins vs ins/del: p=0.007, OR 1.46, 95%CI=1.11-1.93; dominant model: p=0.004, OR 1.47, 95%CI=1.13-1.92 and allele model: p=0.008, OR 1.35, 95%CI=1.08-1.67). This association was stronger in participants over 60 years old, males and smokers. We therefore conclude that the CAA insertion/deletion polymorphism (rs34917480) contributes to non-small cell lung cancer risk in Chinese population. Age, sex and environmental exposure are also related to carcinogenic effects of rs34917480.

The red line of Permanent Basic Farmland is the most important part in the “three-line” demarcation of China’s national territorial development plan. The scientific and reasonable delineation of the red line is a major strategic measure being taken by China to improve its ability to safeguard the practical interests of farmers and guarantee national food security. The delineation of Permanent Basic Farmland zoning (DPBFZ) is essentially a multi-objective optimization problem. However, the traditional method of demarcation does not take into account the synergistic development goals of conservation of cultivated land utilization, ecological conservation, or urban expansion. Therefore, this research introduces the idea of artificial immune optimization and proposes a multi-objective model of DPBFZ red line delineation based on a clone selection algorithm. This research proposes an objective functional system consisting of these three sub-objectives: optimal quality of cropland, spatially concentrated distribution, and stability of cropland. It also takes into consideration constraints such as the red line of ecological protection, topography, and space for major development projects. The mathematical formal expressions for the objectives and constraints are given in the paper, and a multi-objective optimal decision model with multiple constraints for the DPBFZ problem is constructed based on the clone selection algorithm. An antibody coding scheme was designed according to the spatial pattern of DPBFZ zoning. In addition, the antibody-antigen affinity function, the clone mechanism, and mutation strategy were constructed and improved to solve the DPBFZ problem with a spatial optimization feature. Finally, Tongxu County in Henan province was selected as the study area, and a controlled experiment was set up according to different target preferences. The results show that the model proposed in this paper is operational in the work of delineating DPBFZ. It not only avoids the adverse effects of subjective factors in the delineation process but also provides multiple scenarios DPBFZ layouts for decision makers by adjusting the weighting of the objective function.
Tazarotene-Induced Gene 1 Interacts with DNAJC8 and Regulates Glycolysis in Cervical Cancer Cells
Wang, Chun-Hua,Shyu, Rong-Yaun,Wu, Chang-Chieh,Chen, Mao-Liang,Lee, Ming-Cheng,Lin, Yi-Yin,Wang, Lu-Kai,Jiang, Shun-Yuan,Tsai, Fu-Ming Korean Society for Molecular and Cellular Biology 2018 Molecules and cells Vol.41 No.6
The tazarotene-induced gene 1 (TIG1) protein is a retinoidinducible growth regulator and is considered a tumor suppressor. Here, we show that DnaJ heat shock protein family member C8 (DNAJC8) is a TIG1 target that regulates glycolysis. Ectopic DNAJC8 expression induced the translocation of pyruvate kinase M2 (PKM2) into the nucleus, subsequently inducing glucose transporter 1 (GLUT1) expression to promote glucose uptake. Silencing either DNAJC8 or PKM2 alleviated the upregulation of GLUT1 expression and glucose uptake induced by ectopic DNAJC8 expression. TIG1 interacted with DNAJC8 in the cytosol, and this interaction completely blocked DNAJC8-mediated PKM2 translocation and inhibited glucose uptake. Furthermore, increased glycose uptake was observed in cells in which TIG1 was silenced. In conclusion, TIG1 acts as a pivotal repressor of DNAJC8 to enhance glucose uptake by partially regulating PKM2 translocation.

In order to investigate the hysteretic behavior of recycled aggregate concrete with ferronickel slag-filled steel tubular (RAC-FNSFST) columns, the quasi-static loading was implemented on nine specimens with different replacement ratios (RACs), axial load levels, length–diameter ratios, and diameter–thickness ratios. The hysteretic curves, skeleton curves, deformability, energy dissipation capacity, and stiffness degeneration were studied after loading and failure mechanisms were observed, followed by the construction of FE models for parameter analysis. It is demonstrated that the hysteretic loop curve is full, and the hysteretic performance was not dramatically affected by the replacement ratio of RAC. With axial load level increase, ultimate strength at descending stage degrades quickly, stiffness degeneration accelerates, and hysteretic energy dissipation increases. Stiffness degeneration and hysteresis energy dissipation are enhanced as the length–diameter ratio increases. However, when the diameter–thickness ratio decreases, hysteretic energy dissipation increases, and stiffness degeneration accelerates. In addition, a suitable FE model was established and compared with experimental results. Then a wide range of parameter studies was carried out as a supplement to the experimental study. It is shown that the ultimate strength and ductility of specimens are intimately correlated with the RAC strength, yield strength of steel tube, slenderness ratio, axial load level, and steel ratio.
