Although therapies based on direct-acting antivirals (DAAs) effectively eradicate hepatitis C virus (HCV) in patients, there is still a high risk of liver fibrosis even after a sustained virological response. Therefore, it is of great clinical importance to understand the mechanism of potential factors that promote liver fibrosis after virological cure by treatment with DAAs. Here, we found that tubulointerstitial nephritis antigen-like 1 (TINAGL1) is significantly increased in HCV-infected hepatocytes and in the liver of patients with liver fibrosis, and that higher TINAGL1 expression persists in HCV-eradicated hepatocytes after treatment with DAAs.

In soil polluted with benzene, toluene, ethylbenzene, and xylenes (BTEX), oxygen is rapidly depleted by aerobic respiration, creating a redox gradient across the plume. Under anaerobic conditions, BTEX biodegradation is then coupled with fermentation and methanogenesis. This study aimed to characterize this multi-step process, focusing on the interactions and functional roles of key microbial groups involved.

By introducing ester warheads into the hydroxyl groups in lycorine (1), three types of lycorine mono-ester or di-ester analogues were synthesized and evaluated for their antiviral activities against HCoV-OC43. Most of them showed higher selective indexes (SI) than 1, up to nearly 14 times. Using compound 6b as a probe, we firstly demonstrated that lycorine esters directly targeted nidovirus RdRp-associated nucleotidyltransferase (NiRAN) domain in the non-structural protein 12 (nsp 12) by reversibly acylating Cys12 to induce the shrink of NiRAN pocket and block the viral replication, different from the known RdRp inhibitors.

Obesity is a significant risk factor for cardiac arrhythmias, and the ferroptosis is closely related to cardiac arrhythmias. This study aimed to investigate whether puerarin (Pue), a natural isoflavone, could reduce the susceptibility to ventricular arrhythmias (VAs) associated with obesity and inhibit ferroptosis, with a particular focus on the Sirt1/Nrf2 signaling pathway. Male rats were randomly divided into three groups: normal chow diet (NC), high-fat diet (HFD), and HFD with Pue treatment (100mg/kg, HFD + Pue).

Chlorogenic acid (CGA) is a natural product that effectively inhibits tumor growth, demonstrated in many preclinical models, and phase II clinical trials for patients with glioma. However, its direct proteomic targets and anticancer molecular mechanisms remain unknown. Herein, we developed a novel bi-functional photo-affinity probe PAL/CGA and discovered mitochondrial acetyl-CoA acetyltransferase 1 (ACAT1) was one of the main target proteins of CGA by using affinity-based protein profiling (AfBPP) chemical proteomic approach.

Background: As an ancient concept and practice, "food as medicine" or "medicine-food homology" is receiving more and more attention these days. It is a tradition in many regions to intake medicinal herbal food for potential health benefits to various organs and systems including the kidney. Kidney diseases usually lack targeted therapy and face irreversible loss of function, leading to dialysis dependence.

Organic pollutants (OPs) have caused severe environmental contaminations in the world and aroused wide public concern. Autochthonous bioaugmentation (ABA) is considered a reliable bioremediation approach for OPs contamination. However, the rapid screening of indigenous degrading strains from in-situ environments remains a primary challenge for the practical application of ABA.

The relationship between plants and soil microbial communities is complex and subtle, with microbes playing a crucial role in plant growth. Autochthonous bioaugmentation and nutrient biostimulation are promising bioremediation methods for herbicides in contaminated agricultural soils, but how microbes interact to promote biodegradation and plant growth on barren fields, especially in response to the treatment of the herbicide bromoxynil after wheat seedlings, remains poorly understood. In this study, we explored the microbial community reassembly process from the three-leaf stage to the tillering stage of wheat and put forward the idea of using the overlapping results of three methods (network Zi-Pi analysis, LEfSe analysis, and Random Forest analysis) as keystones for the simplification and optimization of key microbial species in the soil.

Dipicolinic acid is an essential component of bacterial spores for stress resistance, which is released into the environment after spore germination. In a previous study, a dip gene cluster was found to be responsible for the catabolism of dipicolinic acid in Alcaligenes faecalis JQ135. However, the transcriptional regulatory mechanism remains unclear.
