... Candidiasis is a fungal infection caused by Candida species which has been reported in most domestic and wild birds and mammals. In this study, 196 samples from different species of birds with suspected symptoms of candidiasis were examined. Pharyngeal swabs, cloacal swabs, and fecal samples were taken from the birds. The samples were cultured in sabouraud dextrose agar (SDA) containing cyclohexim ...
... Lignin enhanced biodegradation of polycyclic aromatic hydrocarbons (PAHs) in soil, but collaboration among soil microorganisms during this process remains poorly understood. Here we explored the relations between microbial communities and PAH transformation in soil microcosms amended with lignin. Mineralization of the four-ring benzo(a)anthracene (BaA), which was selected as a model, was determine ...
... Breast cancer susceptibility gene 2 (BRCA2) mediates genome maintenance during the S phase of the cell cycle, with important roles in replication stress, centrosome replication, and cytokinesis. In this study, we showed that a small heat shock protein, HSP27, interacted with and participated in the degradation of BRCA2 in estrogen-treated MCF-7 cells. BRCA2 degradation reportedly requires ubiquiti ...
... Invitro maturation is an important process in the invitro production of embryos. It has been shown recently that 3 cytokines: fibroblast growth factor 2 (FGF2), leukemia inhibitory factor (LIF), and insulin-like growth factor 1 (IGF1), increase the efficiency of IVM, blastocyst production, and invivo development following somatic cell nuclear transfer (SCNT) in pigs (Yuan et al. 2017 PNAS 114, E57 ...
... As has been shown previously, fibroblast growth factor 2 (FGF2), leukaemia inhibitory factor (LIF), and insulin-like growth factor 1 (IGF1) in combination play a positive role in maintaining the quality of mammalian oocytes maturing invitro. In the present work, we studied the effects of these cytokines in optimal concentrations when added in combination to IVM medium on the nuclear status and dev ...
... Earthworms are an integral part of soil ecosystems, especially for their role in soil functions such as organic matter (OM) decomposition and nutrient cycling. Earthworms and microorganisms are interdependent, and a considerable portion of the contribution earthworms make to influencing OM fate is through interactions with microorganisms. However, the importance of the earthworm-associated microbi ...

Abstract:
... Danhe granule (DHG) is used by Chinese doctors to treat blood stasis, phlegm and dampness. Its lipid-lowering ability has been investigated in our previous research. However, the anti-liver inflammatory and fibrotic effects and mechanism of action of DHG in non-alcoholic steatohepatitis (NASH) have not been explored. To evaluate the ameliorative effects of DHG on liver inflammation and fibrosis in ...
... Inorganic arsenic is widely present in the environment. Exposure to moderate to high concentrations of arsenic from drinking water or air can cause various cancers and multisystem dysfunction. Glucose-regulated protein 78 (GRP78) is an endoplasmic reticulum (ER) stress sensor of unfolded protein response (UPR) under stress conditions and it enhances cell survival. The aim of this study is to inves ...
... It has been implied that deregulation of cyclin D1 turnover under stresses can facilitate genomic instability and trigger tumorigenesis. Much focus has been placed on identifying the E3 ligases responsible for mediating cyclin D1 degradation. However, the findings were quite controversial and cell type-dependent. Little is known about how cyclin D1 is regulated in precancerous cells upon DNA damag ...
... We previously found that pharmacological inhibition of prolyl-tRNA synthetase by halofuginone has potent activity against Nosema ceranae, an important pathogen of honey bees. However, we also observed that prolyl-tRNA synthetase inhibition is toxic to bees, suggesting further work is necessary to make this a feasible therapeutic strategy. As expected, we found that pharmacological inhibition of pr ...
... Since the onset of molecular biology, the ciliate Tetrahymena thermophila has been one of the most convenient single-celled model eukaryotes for genetics, biochemistry, and cell biology. Particularly, thanks to the availability of several different selection markers, it is possible to knock out or knock in genes at multiple genetic loci simultaneously in Tetrahymena, which makes it an excellent mo ...
... Present study demonstrates that conspecific vitellogenin1 (CFVg1) induces oocyte maturation in the catfish, Clarias batrachus. CFVg1 is able to develop fertilizable eggs in the Clarias batrachus. Therefore, different in vitro oocyte culture experiments were designed to see whether CFVg1 has efficacy of oocyte maturation and its pathway. In in vitro oocyte culture experiment, CFVg1 showed a dose- a ...
... Diabetes mellitus is the most common metabolic disease in the world. Herein, insulin- and cholic acid-loaded zein nanoparticles with dextran surfaces were fabricated to enhance the oral absorptions of insulin in the intestine and in the liver which is the primary action organ of endogenous insulin. In the nanoparticles, zein acted as cement to embed insulin, cholic acid and casein by hydrophobic i ...

... Advanced glycated albumin (AGE-albumin) impairs cholesterol efflux and contributes to inflammation in macrophages. The current study evaluated: (1) the persistence of the deleterious effect of AGE-albumin in cholesterol efflux and in inflammation, and (2) how metabolic control in diabetes mellitus (DM) contributes to attenuate the deleterious role of AGE-albumin in macrophage cholesterol homeostas ...

... Bacteria and fungi have been shown to produce nitrous oxide (N₂O) during denitrification, but their contribution after nitrate (NO₃⁻) application to soil is not clearly established. In a microcosm experiment, the relative contribution of bacteria and fungi to N₂O and carbon dioxide (CO₂) production by four contrasting soils representing different land uses after KNO₃ addition was studied. The soil ...
... HIV-1 accessory protein Vif is required for neutralization of cellular restriction factor APOBEC3G through its ubiquitination and proteasomal degradation which allows replication of HIV-1 in non-permissive cells. This function of Vif is required for maintaining the genomic integrity of HIV-1. We here report that the Vif interacts with the cellular E3 ubiquitin ligase CHIP and the level of Vif prot ...

... Background: There is an urgent need for new antivirals with powerful therapeutic potential and tolerable side effects. Methods: Here, we tested the antiviral properties of interferons (IFNs), alone and with other drugs in vitro. Results: While IFNs alone were insufficient to completely abolish replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), IFNα, in combination with re ...

... Ubiquitously eXpressed Transcript isoform 2 (UXTV2) is a prefoldin-like protein involved in NF-κB signaling, apoptosis, and the androgen and estrogen response. UXT-V2 is a cofactor in the NF-κB transcriptional enhanceosome, and its knockdown inhibits TNF-α -induced NF-κB activation. Fbxo7 is an F-box protein that interacts with SKP1, Cullin1 and RBX1 proteins to form an SCF(Fbxo7) E3 ubiquitin lig ...
... In addition to bacteria, the contribution of fungi to nitrous oxide (N₂O) production has been recognized but the responses of these two broad and unrelated groups of microorganisms to global environmental changes, atmospheric nitrogen (N) deposition, and precipitation in terms of N₂O production are unclear. We studied how these two microbial-mediated N₂O production pathways responded to soil moist ...
... Humans are exposed to different contaminants including mycotoxins. Deoxynivalenol (DON), a potent ribosome inhibitor, is a highly prevalent mycotoxin in the food chain worldwide. Although DON is not genotoxic, we previously showed that it exacerbates the genotoxicity of colibactin, a DNA-crosslinking toxin produced by bacteria in the gut. In the present study, we investigated whether this phenotyp ...
