CRISPR-based gene knockout screens reveal deubiquitinases involved in HIV-1 latency in two Jurkat cell models
Authors: Rathore Anurag , Iketani Sho , Wang Pengfei , Jia Manxue , Sahi Vincent , Ho David D.
Published: March 2020

The major barrier to a HIV-1 cure is the persistence of latent genomes despite treatment with antiretrovirals. To investigate host factors which promote HIV-1 latency, we conducted a genome-wide functional knockout screen using CRISPR-Cas9 in a HIV-1 latency cell line model. This screen identified IWS1, POLE3, POLR1B, PSMD1, and TGM2 as potential regulators of HIV-1 latency, of which PSMD1 and TMG2 could be confirmed pharmacologically. Further investigation of PSMD1 revealed that an interacting enzyme, the deubiquitinase UCH37, was also involved in HIV-1 latency. We therefore conducted a comprehensive evaluation of the deubiquitinase family by gene knockout, identifying several deubiquitinases, UCH37, USP14, OTULIN, and USP5 as possible HIV-1 latency regulators. A specific inhibitor of USP14, IU1, reversed HIV-1 latency and displayed synergistic effects with other latency reversal agents. IU1 caused degradation of TDP-43, a negative regulator of HIV-1 transcription. Collectively, this study is the first comprehensive evaluation of deubiquitinases in HIV-1 latency and establishes that they may hold a critical role.

Study of the biological function of LncRNA LUCAT1 on cervical cancer cells by targeting miR-199b-5p
Authors: Yang Ting , Xia Shengnan
Published: March 2020

To explore the effect and mechanism of LncRNA LUCAT1 in cervical cancer (CC). In the present study, 67 cases of CC patients and 60 healthy cases were selected as the research objects. CC patients were selected as the study group (SG) and healthy physical examination patients were selected as the control group (CG). LUCAT1 expression level in peripheral blood was detected in the two groups. Human cervical carcinoma cells C33A, AV3 and normal cervical epithelial cells H8 were purchased for biological behavior analysis. LUCAT1 was highly expressed in SG and cancer tissues (P<0.050), and it had good diagnostic value for the development of CC (P<0.001). It was closely related to the differentiation, pathological stage and metastasis of CC (P<0.001). The prognosis of CC patients was affected (P<0.050). After transfecting LUCAT1 into CC cells, it was found that the proliferation, invasion ability and anti-apoptosis protein of CC cells were significantly reduced, while the apoptosis rate and apoptosis protein were significantly increased by inhibiting LUCAT1 expression (P<0.050). However, after transfecting miR-199b-5p into CC cells, it was found that the proliferation, invasion ability and anti-apoptosis protein of CC cells were significantly increased, while the apoptosis rate and apoptosis protein were significantly decreased by inhibiting LUCAT1 expression (P<0.050). LUCAT1 was highly expressed in CC. It was involved in the tumor development of CC by targeting miR-199b-5p, which was of great significance for the diagnosis and treatment of CC in the future.
Wide field-of-view, high-resolution Solar observation in combination with ground layer adaptive optics and speckle imaging
Authors: Zhong Libo , Zhang Lanqiang , Shi Zhendong , Tian Yu , Guo Youming , Kong Lin , Rao Xuejun , Bao Hua , Zhu Lei , Rao Changhui
Published: March 2020

Context. High angular resolution images at a wide field of view are required for investigating Solar physics and predicting space weather. Ground-based observations are often subject to adaptive optics (AO) correction and post-facto reconstruction techniques to improve the spatial resolution. The combination of ground layer adaptive optics (GLAO) and speckle imaging is appealing with regard to a simplification of the correction and the high resolution of the reconstruction. The speckle transfer functions (STFs) used in the speckle image reconstruction mainly determine the photometric accuracy of the recovered result. The STF model proposed by Friedrich Wöger and Oskar von der Lühe in the classical AO condition is generic enough to accommodate the GLAO condition if correct inputs are given. Thus, the precisely calculated inputs to the model STF are essential for the final results. The necessary input for the model STF is the correction efficiency which can be calculated simply with the assumption of one layer turbulence. The method for calculating the correction efficiency for the classical AO condition should also be improved to suit the GLAO condition. The generic average height of the turbulence layer used by Friedrich Wöger and Oskar von der Lühe in the classic AO correction may lead to reduced accuracy and should be revised to improve photometric accuracy.

Aims. This study is aimed at obtaining quantitative photometric reconstructed images in the GLAO condition. We propose methods for extracting the appropriate inputs for the STF model.

Methods. In this paper, the telemetry data of the GLAO system was used to extract the correction efficiency and the equivalent height of the turbulence. To analyze the photometric accuracy of the method, the influence resulting from the distribution of the atmospheric turbulence profile and the extension of the guide stars are investigated by simulations. At those simulations, we computed the STF from the wavefront phases and convolved it with the high-resolution numerical simulations of the solar photosphere. We then deconvolved them with the model STF calculated from the correction efficiency and the equivalent height to obtain a reconstructed image. To compute the resulting photometric precision, we compared the intensity of the original image with the reconstructed image. We reconstructed the solar images taken by the GLAO prototype system at the New Vacuum Solar Telescope of the Yunnan Astronomical Observatory using this method and analyzed the results.

Results. These simulations and ensuing analysis demonstrate that high photometric precision can be obtained for speckle amplitude reconstruction using the inputs for the model STF derived from the telemetry data of the GLAO system.
Chemical abundance analysis of extremely metal-poor stars in the Sextans dwarf spheroidal galaxy
Authors: Aoki M. , Aoki W. , François P.
Published: March 2020

Context.Metal-poor components of dwarf galaxies around the Milky Way could be remnants of the building blocks of the Galactic halo structure. Low-mass stars that are currently observed as metal-poor stars are expected to have formed in chemically homogeneous clusters in the early phases of galaxy formation. They should have already disintegrated and should exhibit large scatter in abundance ratios of some sets of elements (e.g., Sr/Ba) in the Milky Way field stars. However, chemical abundance ratios are expected to cluster in very metal-poor stars in dwarf galaxies because the number of clusters formed in individual galaxies in the very early phase is expected to be quite limited.

Aims.We examine the possible clustering of abundance ratios of Sr and Ba in the Sextans dwarf galaxy to test for the clustering star formation scenario.

Methods.We investigate a total of 11 elements (C, Mg, Ca, Sc, Ti, Cr, Mn, Ni, Zn, Sr, Ba) in five stars in the Sextans dwarf galaxy. Previous studies suggest that these have similar abundance ratios. In this study, we focus on the abundance ratio of Sr to Ba. The observations are based on high-resolution spectroscopy (R= 40 000) using the Subaru Telescope High Dispersion Spectrograph.

Results.The distribution ofα/Fe abundance ratios of the Sextans dwarf galaxy stars is slightly lower than the average of the values of stars in the Galactic halo. The Sr/Ba abundance ratios for the five metal-poor stars are in good agreement, and this clumping is distinctive compared to the [Sr/Ba] spread seen in the metal-poor halo stars. We find that the probability of such clumping is very small if the Sextans stars have distributions of Sr and Ba abundances similar to halo stars.

Conclusions.In the Sextans dwarf galaxy, five out of six of the extremely metal-poor stars for which abundance ratios are well studied so far show clear clustering in abundance ratios including Sr/Ba. These observations tend to support the hypothesis that these stars were formed from a cloud of homogeneous chemical composition.
Mathematical modeling of Kazakhstan’s CO2 emissions and the role of environmental accounting
Authors: Sultanova Bakyt , Arystambaeva Almira , Abisheva Zhumakul , Kogut Oksana , Shapetov Bibarys
Published: March 2020

The global challenge of the 21st century is climate change. In many ways, these changes are exacerbated by the life of people. The factor that has the greatest negative impact on the environment is greenhouse gas emissions, which continue to grow. Kazakhstan is located at a considerable distance from the World Ocean, with an arid and sharply continental climate in most of the territory. According to data for 1976-2017, Kazakhstan has a faster growth rate of average annual air temperature than the global average. This further enhances the relevance of SDG(Sustainable Development Goals) 13 to the country. In this paper, we analyze the CO2 emissions of Kazakhstan for 2010-2018, and construct a function using linear regression equation.

CIS countries gained independence in the early 1990s. Prior to this, they were republics within the Soviet Union, on the territory of which the Unified Energy System functioned. After the collapse of the USSR, each country in the post-Soviet space was forced to independently solve the problems of supplying its economy with energy. They will build relations with their neighbors in a new way, including in the energy sector. This article presents an analysis of the situation in alternative energy of the EEU member countries (Russia, Kazakhstan, Belarus, Armenia and Kyrgyzstan). At the same time, Russia and Kazakhstan have their own energy resources and even export surplus hydrocarbons. Therefore, they are less concerned about the development of alternative energy. At the same time, Belarus and Armenia are forced to import energy resources. And in the energy sector of Kyrgyzstan, the production of electricity at hydroelectric power plants predominates. Therefore, these states, which are experiencing a shortage of energy resources, are interested in the development of alternative energy. But these states have difficulties financing alternative energy. In general, a situation has developed in the post-Soviet space when foreign investors are actively investing in alternative energy. All projects are aimed at reducing dependence on energy supplies from Russia. At the same time, Russia practically does not take part in investment projects to develop alternative energy for neighboring countries. The article analyzes the mechanisms for implementing investment projects in alternative energy using the EEU countries as an example.

This article discusses the role of innovative digital technologies in medicine to improve its competitiveness and efficiency of organization and management in health care, as well as improving the quality of treatment. Health care shows the diversity of achievements and the flow of innovations based on technology. Most of the innovations that the author will describe here are still at the initial stage of development. Everyone is impressive in their own way. But the good news is that these innovations have been opened up from the traditional healthcare system to “unified medicine”. The goal is to identify and prevent the disease, along with treatment. In an outdated model of medicine, the necessary data is scattered between paper files, or classified into an electronic medical record system. Today, its improved model is being implemented. This is an individual technology for continuous monitoring of vital functions and comprehensive presentation of information about the patient’s health status. The development of information technologies and home self-monitoring devices leads to the creation of convenient services for remote consultation of citizens who care about their health.

Sustainable socio-economic development of the region can be achieved only if the strategic priority of development is a socially significant goal-improving the quality of life of the population. A system of quality of life’s indicators includes both objective characteristics of a person or society, their life and standards of it and subjective estimated characteristics, that show subject’s attitude to his life’s realities. Demographical indicators, that characterize regularities of human reproduction, take an important place in the system of indicators, that determine quality of life. The “Concept of sustainable development” itself has a direct reproductive content and implies sustainable reproduction of a person, his quality parameters and living conditions, consistent with the laws of development and the principles of conservation of the natural environment. The issues of improving demographic indicators of the quality of life of the population are particularly relevant for the Almaty region – a region with a high demographic and labor potential, which plays an important role in the socio-economic and geopolitical development of the Republic, as a region with an agricultural orientation, occupying a transit position.

The housing market is one of the most important segments of the economy of any country. As part of the study, it is shown that it is not enough to consider the housing market financing system only in the organizational and structural aspect. The application of a structurally functional approach is essential, which will improve the efficiency of market financing. The author determines the need for the formation of auto-regulators that can reduce the need for manual control of the economy of the housing complex and the state, which is especially important in the modern economic system. The study identified such auto-regulators as the inclusion of borrowers in the quality management system and the usefulness of housing finance; organization of interaction of market and state financing based on the principles of public-private partnership; the need for a system of indicators to assess the development of the Russian housing market, improving the information support of financial markets; the formation of an open system for monitoring the status of the housing market financing system.

Published: March 2020

The article is devoted to the consideration of such a phenomenon as the debt load of the country’s population on the example of Russia. The term “debt” means the ratio between debt obligations and available income. Assessing the level of debt or, in other words, the debt burden of Russian citizens is relevant, because real disposable incomes have a rather long downward trend, and consumer unsecured lending is becoming more affordable, the amount of debt to Russians to creditors is increasing year by year, while the share of overdue liabilities, although not very large, still poses certain risks. This situation increases the level of debt to citizens, which poses serious challenges for the socio-economic development of the state, since excessive debt burden can lead to a crisis (as, for example, in the USA in 2008). Therefore, it is especially important to soberly assess the level of debt load and take appropriate measures in time to regulate it, in particular, to cool the consumer lending market as the most volatile segment of lending to individuals.

Modern globalization and global integration increase the importance of social processes in the economy, while the human factor plays a significant role in all spheres. Sustainable development in general and certain areas of life, including tax relations, are no exception. Taxes are a socially necessary phenomenon, the basis of the financial mechanism for sustainable development, and are the most important basic regulator of social progress. Through taxes, a social balance is achieved between public, corporate, and personal economic interests. The article examines the existing models of tax relations (characterizing the interaction of the state and taxpayers from the point of view of the principles of force, law and partnership), the possibility of their successful implementation and improvement. The current model of tax relations in the state entails appropriate tax behavior on the part of taxpayers and tax authorities. Tax behavior models are based on a certain level of tax culture and morality, which is formed under the influence of a number of objective and subjective factors. Tax culture, tax behavior and discipline, the process of interaction between the state and taxpayers (the level of development of tax relations) and determine the degree of protection of national interests and sustainable development.
