Abstract From late December 2019 a new human-adapted coronavirus, SARS-CoV-2, was observed and isolated in
clustered patients in Wuhan, China. It has been proved to be able to transmit human-to-human and cause
pneumonia, leading to about 2% fatality. Its genome characteristics, immune responses and related potential
treatments, such as chemical drugs, serum transfusion and vaccines including DNA vaccines, are discussed in this
review for a brief summary. More >

Abstract Focal adhesions are polyproteins linked to extracellular matrix and cytoskeleton, which play an important role
in the process of transforming force signals into intracellular chemical signals and subsequently triggering related
physiological or pathological reactions. The cytoskeleton is a network of protein fibers in the cytoplasm, which is
composed of microfilaments, microtubules, intermediate filaments, and cross-linked proteins. It is a very important
structure for cells to maintain their basic morphology. This review summarizes the process of fluid shear stress
transduction mediated by focal adhesion and the key role of the cytoskeleton in this process, which focuses on the
focal adhesion and… More >

Abstract Because of its antitumor therapeutic-activity, as well as its application in food industries to improve the quality,
L-asparaginase has attracted considerable attention from several investigators. In recent years, fungi have occupied
advanced rank among microorganisms in the production process of the enzyme. This review is spotting the light on
the advantages of fungal enzyme and its applications in the food industry and medications. The solid-state
fermentation was discussed as the wide alternative and most accepted biosynthesis technique. However, some lights
were also spotted to the statistical experimental design of the fermentation process, mainly on the methodology of the
response surface… More >

Abstract Prophages are temperate phages integrated into the host bacterial genome. They play an important role in the
adaptation and the pathogenicity of bacteria, especially pathogenic bacteria. In this review, we described the distribution
of prophages in different hosts and different environments, and focused on the significance of prophages. At the singlecell level, prophages can help the host adapt to harsh external environments by directly carrying virulence genes, encoding
regulatory factors and activating lysogeny. At the population level, prophages can influence the overall evolutionary
direction and ecological function of the host bacterial community. This review will help us understand the important… More >

Abstract Pathogenesis of chronic myeloid leukemia (CML) has mostly been studied with regard to the oncogenic role
of BCR/ABL fusion; however, recent disclosures have declared that the challenges with the treatment of CML patients
would not be resolved until the role of other aberrancies is ignored. Given the involvement of cyclin-dependent kinases
(CDKs) in the pathogenesis of CML, the present study aimed to investigate the effects of a multi-CDK inhibitor
AT7519 on BCR/ABL-harboring CML-derived K562 cells. Our results showed that AT7519 effectively reduced the
survival of K562 and induced its anti-proliferative effect through the induction of G2/M arrest due to elevated… More >

Abstract We investigated the effect of black sea bream extracts on changes in pro-inflammatory and anti-inflammatory
cytokines induced by lipopolysaccharide (LPS) in murine splenocytes. The levels of pro-inflammatory cytokines
[interleukin (IL)-6, tumor necrosis factor-α (TNF-α), IL-12/IL-23(p40) and IL-17A] and anti-inflammatory cytokines
[IL-4, IL-10 and interferon-γ (IFN-γ)] were assessed. Incubation of murine splenocytes with acetone+methylene
chloride (A+M) and methanol (MeOH) extracts significantly decreased LPS-induced IL-6, IL-12/IL-23(p40) and
IL-17A productions after 6 h incubation (p < 0.05). The A+M and MeOH extracts significantly increased LPS-induced
IL-4 and IFN-γ productions at 48 and 72 h incubation (p < 0.05). Treatment with A+M extract resulted… More >

Abstract Spermatogenesis is a highly efficient and intricate process in the testis by which mature spermatozoa are
produced daily to maintain lifelong male fertility. Essential to this process are spermatogonia capable of both
proliferation and differentiation. Nevertheless, the underlying mechanisms for spermatogonial proliferation and
differentiation remain poorly understood. MicroRNAs (miRNAs) are a category of non-coding small RNAs with
regulatory functions by binding to the 3’ untranslated region (UTR) of the target mRNA. Previous studies have
demonstrated that miRNAs are capable of modulating cell proliferation, differentiation and apoptosis, but the roles of
individual miRNAs in spermatogonial fate determination remain largely elusive. Here,… More >

Abstract The Escherichia coli (E. coli) is prevailing worldwide, but the epidemiology of E. coli infections feature regional
distribution characteristics to some extent. E. coli, as a zoonotic pathogen, can be transferred from animals to humans
through food chain or via contact with wounds, causing a public health risk. We reported the swelling of
proventriculus and tracheal bleeding following the death in two broiler chickens (Gallus gallus domesticus) from
Beijing, China. To investigate whether a virus was involved in the infection, Madin Darby Bovine Kidney (MDCK)
cells were co-cultured with supernatants of proventriculus, trachea and spleen homogenates. The avian leucosis virus… More >

Abstract Studies have found that a large number of inflammatory cells, P-selectin, and mature dendritic cells (DCs) are
expressed in the damaged and shoulder parts of atherosclerotic plaque, which demonstrates that P-selectin and mature
DCs participate in the immune inflammatory response leading to the development of atherosclerosis. However, it is
unclear how the above factors interact in this setting. In this study, we investigated the role of P-selectin and its
receptor, P-selectin glycoprotein ligand (PSGL)-1 in atherosclerosis, with the finding that DC surface marker
expression was consistently high in the P-selectin group while consistently low in the PGSL-1 + DCs group,… More >

Abstract Most studies focus on the adaptive immune cells in the GVHD pathogenesis, while little is known about innate
immune cells in GVHD occurrence and development, especially macrophages. Meanwhile, a higher incidence of graft
versus host disease (GVHD) is also found in the elderly patients. Though advances have been made in the
modification of macrophages influenced by the inflamm-ageing, there is still no review on the role of macrophages in
GVHD and the association between GVHD and the altered macrophages by inflamm-ageing. In this review, we focus
on the potential age-related modifications of macrophage in GVHD, which contributes to the change… More >

Abstract While phthalate acid esters (PAEs) cannot fluoresce alone, they can be detected by fluorescence spectroscopy
after chelation with bovine serum albumin (BSA). In this study, the types of amino acid residues at the active site of PAEs
chelated with BSA were determined using molecular docking technology. A modification scheme of BSA with higher
detection sensitivity fluorescence spectroscopy for PAEs was proposed based on the docking results and constructed
for a novel BSA structure with a higher detection sensitivity of fluorescence spectroscopy using a homologous
modeling method. Density functional theory (DFT) was employed to explore the influence before and after BSA… More >

Abstract In this study, we used a meta-analysis method to evaluate the relationship between hypoxia-inducible factor-1α
(HIF1α) 1772C/T gene polymorphism (rs 11549465) and renal cell carcinoma (RCC)/prostate cancer risk. We searched
for relevant studies (before March 1, 2019) on Cochrane Library, Embase, and PubMed. Studies meeting the inclusion
criteria were recruited into this meta-analysis. The outcome of dichotomous data was showed in the way of odds
ratios (OR), and 95% confidence intervals (CI) were also counted. In this investigation, there was no association
between HIF1α 1772C/T gene polymorphism and susceptibility to RCC in Caucasians, Asians as well as overall
populations. In… More >

Abstract It is known that the high electronegativity of fluorine affects various soft tissues, especially the bone structure in
organisms. Of these tissues are the kidneys, which play an important role in the excretion of fluoride from the body.
Fluoride affects many cellular mechanisms. One of these effects is DNA damage. Our study aimed to investigate the
likely protective effect of cholecalciferol (vitamin D3) on genomic DNA damage-induced NaF depending on
concentration and time. The IC25 and IC50 values of NaF for 3, 12 and 24 h and optimum dose of increase in
proliferation to vitamin D3 through MTT assay in… More >
