Annonaceous acetogenins mimic AA005 targets mitochondrial trifunctional enzyme alpha subunit to treat obesity in male mice.

Obesity and related diseases pose a major health risk, yet current anti-obesity drugs inadequately addressing clinical needs. Here we show AA005, an annonaceous acetogenin mimic, resists obesity induced by high-fat diets and leptin mutations at non-toxic doses, with the alpha subunit of the mitochondrial trifunctional protein (HADHA) as a target identified through proteomics and in vitro validation. Pharmacokinetic analysis shows AA005 enriches in adipose tissue, prompting the creation of adipose-specific Hadha-deficient mice.

Untangling determinants of gut microbiota and tumor immunologic status through a multi-omics approach in colorectal cancer.

The changes in gut microbiota have been implicated in colorectal cancer (CRC). The interplays between the host and gut microbiota remain largely unclear, and few studies have investigated these interplays using integrative multi-omics data. In this study, large-scale multi-comic datasets, including microbiome, metabolome, bulk transcriptomics and single cell RNA sequencing of CRC patients, were analyzed individually and integrated through advanced bioinformatics methods.

induced antitumor immunity and synergized with anti-programmed cell death 1 to reduce tumor burden in mice.

The gut microbiota was emerging as critical regulatory elements in shaping the outcome of cancer immunotherapy. However, the underlying mechanisms by which the gut commensal species enhance antitumor immunity remain largely unexplored. Here, we show that the gut microbiota from healthy individuals conferred considerable sensitivity to anti-PD-1 in the colorectal cancer (CRC) tumor-bearing mice, whereas gut microbiota from CRC patients failed to do so.

Fatty liver is a sensitive early warning for hypertension and its complication in the Chinese population.

Objective: The patient of hypertension and its complication increase fast in the past years. Obesity is thought to be a risk factor for hypertension, and BMI (body mass index) is widely used to evaluate the obesity and hypertension risk. However, the abdominal obesity and visceral fat accumulation are more obvious in the East Asian population.

Gut and Cutaneous Microbiome Featuring Abundance of Protected Against Psoriasis-Like Inflammation in Mice.

Background: Psoriasis is a chronic autoinflammatory skin disease, and its aetiology remains incompletely understood. Recently, gut microbial dysbiosis is found to be tightly associated with psoriasis.

Objective: We sought to reveal the causal role of gut microbiota dysbiosis in psoriasis pathogenesis and investigate the protective effect of healthy commensal bacteria against imiquimod -induced psoriasis-like skin response.

Calorie restriction conferred improvement effect on long-term rehabilitation of ischemic stroke via gut microbiota.

Calorie restriction can modulate the gut microbiota and protect against many diseases including ischemic stroke. However, the role of calorie-restriction-induced microbiota alteration remained unknown in ischemic stroke rehabilitation. Here we conducted 30% reduction of caloric intake on mice for four weeks, to evaluate its role on ischemic stroke rehabilitation.

Pectin supplement significantly enhanced the anti-PD-1 efficacy in tumor-bearing mice humanized with gut microbiota from patients with colorectal cancer.

Anti-PD-1-based immunotherapy has emerged as a promising therapy for several cancers. However, it only benefits a small subset of colorectal cancer (CRC) patients. Mounting data supports the pivotal role of gut microbiota in shaping immune system.

Integrated proteomics and metabolomics analysis of tea leaves fermented by Aspergillus niger, Aspergillus tamarii and Aspergillus fumigatus.

Post-fermented Pu-erh tea (PFPT) is a microbially-fermented tea with distinct sensory qualities and multiple health benefits. Aspergillus are the dominant fungi in the fermentation and the main contributors to the characteristics of PFPT, so their underlying functions warrant detailed study. Here, tea leaves were fermented by Aspergillus niger, Aspergillus tamarii and Aspergillus fumigatus, and resulting samples (designated as Asn, Ast and Asf, respectively) were analyzed by proteomic and metabolomic methods.

The up-regulation of NDRG1 by HIF counteracts the cancer-promoting effect of HIF in VHL-deficient clear cell renal cell carcinoma.

Background: Hypoxia-inducible factors (HIFs) are thought to play important roles in the carcinogenesis and progression of VHL-deficient clear cell renal cell carcinoma (ccRCC).

Methods: The roles of HIF-1/2α in VHL-deficient clear cell renal cell carcinoma were evaluated by bioinformatics analysis, immunohistochemistry staining and Kaplan-Meier survival analysis. The downstream genes that counteract the cancer-promoting effect of HIF were analysed by unbiased proteomics and verified by in vitro and in vivo assays.

A real-world 1:1 propensity-matched study revealed unmarried status was independently associated with worse survival for patients with renal clear cell carcinoma.

: Marital status has been reported as an independent prognostic factor for survival in various cancers, but it has been rarely studied in renal clear cell carcinoma (ccRCC). In this study, we aimed to assess the impact of marital status on the survival of ccRCC patients. : We retrospectively investigated the Surveillance, Epidemiology, and End Results (SEER) database and identified 68599 of ccRCC patients between 1973 and 2015.

Diet Consisting of Balanced Yogurt, Fruit, and Vegetables Modifies the Gut Microbiota and Protects Mice against Nonalcoholic Fatty Liver Disease.

Background: Calorie restriction (CR) is a therapeutically effective method for nonalcoholic fatty liver disease. However, the compliance of the CR method is relatively poor. New CR methods are needed.

A real-world study of socioeconomic factors with survival in adults aged 18-64 years with renal cell carcinoma.

To evaluate the impact of socioeconomic factors (SEFs) on survival of renal cell carcinoma (RCC) patients. RCC patients diagnosed between 2007 and 2015 were collected from the SEER database. The crude and multivariate Cox regression analysis was used to identify the independent prognostic factors and quantity the mortality risks for overall survival (OS).

Alcohol and HBV synergistically promote hepatic steatosis.

Background And Aims: Hepatitis virus and alcohol are the main factors leading to liver damage. Synergy between hepatitis B virus (HBV) and alcohol in promoting liver cell damage and disease progression has been reported. However, the interaction of HBV and ethanol in hepatic steatosis development has not been fully elucidated.

[An analysis on funded theses in the Chinese Journal of Parasitology and Parasitic Diseases in 2009-2012].

The published articles of the Chinese Journal of Parasitology and Parasitic Diseases in 2009-2012 (including original articles, experimental researches, field researches and clinical researches) were statistically analyzed. Together 258 research papers were published in the 4 years, and funded papers occupied 82.2% (212/258).

[Soil nutrients spatial variability and soil fertility suitability in Qujing tobacco-planting area].

By adopting GPS technique, 2088 sampling sites were installed in the tobacco-planting area of Qujing City, Yunnan Province, with 0-20 cm soil samples collected to determine their main nutrients contents. The overall characteristics and spatial variability of the tobacco soil nutrients were analyzed by classic statistics and geo-statistics, and the soil fertility suitability in planting tobacco was evaluated by the methods of fuzzy mathematics. In the study area, soil pH and soil organic matter, available S, and water-soluble Cl contents were appropriate, soil total N and alkalihydrolyzable N contents were too high, soil available K, Ca, Mg, Cu, Fe, Zn, Mo, and Mn contents were abundant, soil available P content was at medium level, while soil total P and K and available B contents were insufficient.

[FTIR study of the endurance to Al of different soybean cultivars].

The spectra of root, stem, leaf of soybean samples with 0, 20, 40, 60 mg x L(-1) Al3+ were determined by Fourier transform infrared (FTIR) spectrometry with OMNI-sampler. Little difference was found in the spectra of leaf between two soybean cultivars, aluminum-resistant cultivar Zhechun NO. 2 and aluminum-sensitive cultivar Zhechun NO.
