Serum trimethylamine N-oxide and its precursors are associated with the occurrence of mild cognition impairment as well as changes in neurocognitive status.

Background: This study aims to examine the association between gut microbe-dependent trimethylamine N-oxide (TMAO) and its precursors (choline, betaine, and carnitine) levels and mild cognition impairment (MCI), alongside changes in the Chinese version of the Montreal Cognitive Assessment-Basic (ΔMoCA-BC) score in rural adults.

Methods: Drawing data from a large-scale epidemiological study conducted in rural areas of Fuxin County, Liaoning Province, China. 1,535 participants free from brain-related ailments were initially surveyed.

Prophylactic treatment with and counteracts hepatic NK cell immune tolerance in nonalcoholic steatohepatitis induced by high fat diet.

Hepatic immunity is one of the driving forces for the development of nonalcoholic steatohepatitis (NASH), and targeting gut microbiota is believed to affect the hepatic immune constitution. Here, we aimed to investigate the hepatic immunological state in NASH, with a specific emphasis on natural killer (NK) cells. In addition, we aimed to identify the contributing species that target hepatic immunity to provide new directions and support the feasibility of immunotherapy for NASH.

and Prevent NAFLD by Regulating FXR Expression and Gut Microbiota.

Background And Aims: Non-alcoholic fatty liver disease (NAFLD) is closely associated with gut microbiota and has become the most common chronic liver disease worldwide, but the relationship between specific strains and NAFLD has not been fully elucidated. We aimed to investigate whether and could prevent NAFLD, the effects of their action alone or in combination, possible mechanisms, and modulation of the gut microbiota.

Methods: Mice were fed with high-fat diets (HFD) for 20 weeks, in which experimental groups were pretreated with quadruple antibiotics and then given the corresponding bacterial solution or PBS.

Procyanidin B2 induces apoptosis and autophagy in gastric cancer cells by inhibiting Akt/mTOR signaling pathway.

Background: Procyanidin B2 (PB2), a unique component of the grape seed and other medicinal plants. PB2 has shown wide anticancer activity in various human cancer cells. However, it remains unclear about the biological effects and associated mechanisms of PB2 on gastric cancer cells.

Knockdown of ghrelin-O-acyltransferase attenuates colitis through the modulation of inflammatory factors and tight junction proteins in the intestinal epithelium.

Ghrelin-O-acyltransferase (GOAT) is a membrane-bound enzyme that attaches eight-carbon octanoate to a serine residue in ghrelin and thereby acylates inactive ghrelin to produce active ghrelin. In this study, we investigated the function of GOAT in the intestinal mucosal barrier. The intestinal mucosal barrier prevents harmful substances such as bacteria and endotoxin from entering the other tissues, organs, and blood circulation through the intestinal mucosa.

Transcriptome profiling of cancer tissues in Chinese patients with gastric cancer by high-throughput sequencing.

Gastric cancer (GC) is the fifth most common malignancy and the third leading cause of cancer-associated mortality worldwide. Therefore, there is a requirement to identify sufficiently sensitive biomarkers for GC. Genome-wide screening of transcriptome dysregulation among cancerous and normal tissues may provide insights into the underlying molecular mechanisms of GC initiation and progression.

Ghrelin inhibition of ethanol-induced gastric epithelial cell apoptosis is mediated by miR-21.

Aim: To investigate the underlying mechanism of ghrelin-induced gastro-protection in a cell culture model of ethanol-induced gastric epithelial cell injury.

Methods: The human gastric epithelial cell line GES-1 was incubated with ghrelin (0.01-1 µM), 1 µM ghrelin and 1 µM D-Lys3-growth hormone releasing peptide-6 (GHRP-6), or 1 µM ghrelin and 400 nM antagomiR-21 for 24 h, followed by treatment with 8% ethanol for 3 h to induce apoptosis.

[Expression and significance of SARI and CCN1 in human colorectal carcinomas].

Objective: To explore the expressions of SARI (suppressor of AP-1, regulated by IFN) and connective tissue growth factor/cysteine-rich 61/nephroblastoma-1 (CCN1) and clarify their influences on the occurrence, development and prognosis of colorectal carcinoma (CRC).

Methods: Real-time PCR (polymerase chain reaction) was used to confirm the expressions of SARI and CCN1 at the mRNA level in 32 fresh tissue samples. And the expressions of Caco-2, HT-29 and Lovo were also detected by RT-PCR (reverse transcription-PCR) in cell lines.
