A drug's biological half-life is defined as the time required for the human body to metabolize or eliminate 50% of the initial drug dosage. Correctly measuring the half-life of a given drug is helpful for the safe and accurate usage of the drug. In this study, we investigated which gene ontology (GO) terms and biological pathways were highly related to the determination of drug half-life. The investigated drugs, with known half-lives, were analyzed based on their enrichment scores for associated GO terms and KEGG pathways...

MicroRNA-24 (miR-24), a member of the miRNA family, functions as an oncogene in various types of human cancer. However, the underlying mechanisms of miR-24 involvement in the development and progression of hepatocellular carcinoma (HCC) remain poorly understood. The present study revealed that miRNA-24 down-regulates p53 through binding to the 3'-UTR of p53 mRNA based on a luciferase reporter assay, and that the expression level of miR-24 could affect the invasion of HCC lines via p53. Down-regulation of p53 significantly attenuated the inhibitory effects of miR-24 knockdown on the invasion of HCC cells, suggesting that miR-24 could be a potential target for HCC treatment...

Colorectal cancer (CRC) is a leading cause of cancer-related deaths with an increasing incidence in China. The aberrant expression of angiomotin (AMOT) has been confirmed in a variety of tumors and can interact with Yes-associated protein (YAP) to either promote or suppress the progression of cancer. Unfortunately, its role in CRC remains poorly elucidated. Herein, higher levels of AMOT were observed in CRC cell lines. Upregulation of AMOT in LoVo cells markedly increased cell proliferation and apoptotic resistance to 5-fluorouracil...

Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is an autosomal recessive disorder resulting from biallelic mutations of the SLC25A13 gene. Due to the lack of well‑recognized clinical or biochemical diagnostic criteria, the definitive diagnosis of this disease relies on the genetic analysis of SLC25A13 at present. As novel large deletion/insertion mutations of the SLC25A13 gene are difficult to detect using routine DNA analytic approaches, the timely diagnosis of patients with these types of mutations remains a challenge...

The triggering receptor expressed on myeloid cells 2 (TREM-2) is suggested to be involved in the development of certain human malignancies. However, the functions of TREM-2 in renal cell carcinoma (RCC) are still less known. To reveal the effects of TREM-2 on the RCC progression, we examined the TREM-2 expression in RCC tumor tissues. Then, we analyzed the cell proliferation, cell apoptosis, cell cycle and expression of the relative factors in two selected RCC cell lines post RNA interference. We also analyzed the functions of TREM-2 in an in vivo nude mouse model...

In the present study, we aimed to reveal the molecular mechanisms responsible for the differentiation of human adipose tissue-derived stem cells (hASCs) into myocytes and osteoblasts. Microarray data GSE37329 were obtained from the Gene Expression Omnibus database, including three hASC cell lines from healthy donors, two osteogenic lineages and two myogenic lineages from the in vitro‑induction of hASCs. Differentially expressed genes (DEGs) in the two lineages were firstly screened. Subsequently, the underlying functions of the two sets of DEGs were investigated by Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, followed by protein-protein interaction (PPI) network construction...

Disabled-2 (Dab2) is a widely expressed clathrin binding endocytic adaptor protein and known for the endocytosis of the low-density lipoprotein (LDL) family receptors. Dab2 also modulates endosomal Ras/MAPK (Erk1/2) activity by regulating the disassembly of Grb2/Sos1 complexes associated with clathrin-coated vesicles. We found that the most prominent phenotype of Dab2 knockout mice was their striking lean body composition under a high fat and high caloric diet, although the weight of the mutant mice was indistinguishable from wild-type littermates on a regular chow...

Liver and liver cyst volume measurements are important quantitative imaging biomarkers for assessment of disease progression in autosomal dominant polycystic kidney disease (ADPKD) and polycystic liver disease (PLD). To date, no study has presented automated segmentation and volumetric computation of liver and liver cysts in these populations. In this paper, we proposed an automated segmentation framework for liver and liver cysts from bounded abdominal MR images in patients with ADPKD. To model the shape and variations in ADPKD livers, the spatial prior probability map (SPPM) of liver location and the tissue prior probability maps (TPPMs) of liver parenchymal tissue intensity and cyst morphology were generated...

Exposure to whole-body vibration (WBV) presents an occupational health risk and several safety standards obligate to measure WBV. The high cost of direct measurements in large epidemiological studies raises the question of the optimal sampling for estimating WBV exposures given by a large variation of exposure levels in real worksites. This paper presents a new approach to address this problem. A daily exposure to WBV was recorded for 9 to 24 days among 48 all-terrain vehicle drivers. Four datasets based on root mean squared recordings were obtained from the measurement...

The synthetic transformation of polypeptides with molecular accuracy holds great promise for providing functional and structural diversity beyond the proteome. Consequently, the last decade has seen an exponential growth of site-directed chemistry to install additional features into peptides and proteins even inside living cells. The disulfide rebridging strategy has emerged as a powerful tool for site-selective modifications since most proteins contain disulfide bonds. In this Review, we present the chemical design, advantages and limitations of the disulfide rebridging reagents, while summarizing their relevance for synthetic customization of functional protein bioconjugates, as well as the resultant impact and advancement for biomedical applications...
