Actein is isolated from the rthizomes of Cimicifuga foetida, which is a triterpene glycoside, displaying suppressive effects on breast cancer cells proliferation. However, the effects of actein treatment on liver injury, tending to cancer, have little to be known. Thus, the study is conducted to explore the role of actein in early liver cancer. Diethylnitrosamine (DEN) was used to induce liver cancer in mice followed by actein treatment at different concentrations. DEN caused steatohepatitis supported by fibrosis and inflammation, which were ameliorated for actein administration...

MiR-150, a member of small non-coding RNAs, has been proven to dysregulate in different types of tumor and bear on carcinogenesis and cancer prognosis by regulating the expression of a series of gene including utrophin. Given that utrophin can compensate for dystrophin's absence and be regarded as a promising therapeutic target for Duchenne Muscular Dystrophy (DMD), we further detected the deep role of miR-150 in dystrophic muscle. Using a range of bioinformatic, molecular and cell biology techniques, we declared that miR-150 directly targets cyclin-dependent kinase 3 (CDK3) and leads to the regulation of CDK3 gene expression in both muscle-derived and non-muscle cells...

Untargeted metabolomic profiling has been widely used in recent years. However, the low reproducibility of the data-dependent acquisition (DDA) strategy presents a major bottleneck that considerably limits the reliability of metabolomic studies in biological and clinical research. The data-independent acquisition (DIA) strategy is proposed to solve the above-mentioned problem, and it is gaining popularity. This paper presents a novel approach for performing metabolomic analysis using an untargeted, liquid chromatography-data independent-mass spectrometry (LC-DIA-MS) strategy on a quadrupole-Orbitrap platform...

Human umbilical cord-derived mesenchymal stem cells (UC-MSCs) are considered an attractive cell source for tissue regeneration. However, environmental oxidative stress can trigger premature senescence in MSCs and thus compromises their regenerative potential. Extracellular matrix (ECM) derived from MSCs has been shown to facilitate cell proliferation and multilineage differentiation. This investigation evaluated the effect of cell-deposited decellularized ECM (DECM) on oxidative stress-induced premature senescence in UC-MSCs...
