miRNA profiling in the hippocampus of attention-deficit/hyperactivity disorder rats.

Attention-deficit/hyperactivity disorder (ADHD) is characterized by attention  deficit, hyperactivity, impulsivity, and learning and memory impairment. Although the pathogenesis of learning and memory impairment is still unknown, some studies have suggested an association with hippocampus dysfunction. We aimed to explore the role of miRNAs in the learning and memory impairments observed in ADHD.

Genipin Reverses HFD-Induced Liver Damage and Inhibits UCP2-Mediated Pyroptosis in Mice.

Background/aims: Liver damage is a typical manifestation of nonalcoholic fatty liver disease (NAFLD). It originates from excessive fat accumulation, leading to hepatocyte death, inflammation, and fibrosis. Nonalcoholic steatohepatitis (NASH) is a type of NAFLD with a prevalence of 49% in morbidly obese patients.

Long Noncoding RNA EGFR-AS1 Promotes Cell Proliferation by Increasing EGFR mRNA Stability in Gastric Cancer.

Background/aims: LncRNA EGFR-AS1 is an antisense transcript of EGFR, which plays a key role in gastric cancer progression. This study was aimed to explore the effects of lncRNA EGFR-AS1 on GC and the underling mechanisms.

Methods: The silencing of EGFR-AS1 expression was performed by using EGFR-AS1 shRNA lentivirus in MGC803 and SGC-7901 GC cell.

Profiling Analysis Reveals the Potential Contribution of Peptides to Human Adipocyte Differentiation.

Purpose: Peptide drugs provide promising regimes in anti-obesity treatment. In order to identify potential bioactive peptides involved in adipogenesis.

Experimental Design: The intracellular peptides between preadipocytes and adipocytes are compared by liquid chromatography/mass spectrometry.

Identification and characterization of metformin on peptidomic profiling in human visceral adipocytes.

To gain insight into the effect of metformin on losing weight from peptidomic perspective and to screen potential active peptides for reducing fat lipid deposition. After determining the proper concentration of metformin on human primary visceral adipocytes, we constructed a comparative peptidomic profiling between control and metformin treatment group (n = 3) using a stable isobaric labeling strategy involving tandem mass tag reagents, followed by liquid chromatography tandem mass spectrometry. We identified and quantified 3065 non-redundant peptides, 304 of which were differentially expressed after metformin treatment, 206 peptides were up regulated and 98 peptides were down regulated significantly.

GM13133 is a negative regulator in mouse white adipocytes differentiation and drives the characteristics of brown adipocytes.

Obesity is tightly associated with the disturbance of white adipose tissue storing excess energy. Thermogenic adipocytes (brown and beige) exert a critical role of oxidizing nutrients at the high rates through non-shivering thermogenesis. The recruitment of brown characteristics in white adipocytes, termed browning, has been considered as a promising strategy for treating obesity and associated metabolic complications.
