Deciphering the effects of PYCR1 on cell function and its associated mechanism in hepatocellular carcinoma.

Overexpression of pyrroline-5-carboxylate reductase 1 (PYCR1) has been associated with the development of certain cancers; however, no studies have specifically examined the role of PYCR1 in hepatocellular carcinoma (HCC). Based on The Cancer Genome Atlas expression array and meta-analysis conducted using the Gene Expression Omnibus database, we determined that was upregulated in HCC compared to adjacent nontumor tissues (P < 0.05).

Diagnostic and prognostic value of MCM3 and its interacting proteins in hepatocellular carcinoma.

Aberrant DNA replication is one of the driving forces behind oncogenesis. Furthermore, minichromosome maintenance complex component 3 (MCM3) serves an essential role in DNA replication. Therefore, in the present study, the diagnostic and prognostic value of MCM3 and its interacting proteins in hepatocellular carcinoma (HCC) were investigated.

IVS8-5T Allele of CFTR is the Risk Factor in Chronic Pancreatitis, Especially in Idiopathic Chronic Pancreatitis.

Background: Cystic fibrosis transmembrane conductance regulator IVS8-5T gene variation appears to be associated with a higher risk of chronic pancreatitis (CP); however, there is inconsistency between previous reported studies. Here, we performed a meta-analysis to investigate this relationship.

Materials And Methods: PubMed and WANFANG databases were searched for the case-control studies that contained Patients with CP with IVS8-5T variation.

Anti-G250 nanobody-functionalized nanobubbles targeting renal cell carcinoma cells for ultrasound molecular imaging.

Traditional imaging examinations have difficulty in identifying benign and malignant changes in renal masses. This difficulty may be solved by ultrasound molecular imaging based on targeted nanobubbles, which could specifically enhance the ultrasound imaging of renal cell carcinomas (RCC) so as to discriminate benign and malignant renal masses. In this study, we aimed to prepare anti-G250 nanobody-functionalized targeted nanobubbles (anti-G250 NTNs) by coupling anti-G250 nanobodies to lipid nanobubbles and to verify their target specificity and binding ability to RCC cells that express G250 antigen and their capacity to enhance ultrasound imaging of RCC xenografts.

Transcriptomic profiling of chemical exposure reveals roles of Yap1 in protecting yeast cells from oxidative and other types of stresses.

Transcriptomic profiles are generated by comparing wild-type and the yeast yap1 mutant to various chemicals in an attempt to establish a correlation between this gene mutation and chemical exposure. Test chemicals include ClonNAT as a non-genotoxic agent, methyl methanesulphonate (MMS) as an alkylating agent, tert-butyl hydroperoxide (t-BHP) as an oxidative agent and the mixture of t-BHP and MMS to reflect complex natural exposure. Differentially expressed genes (DEGs) were identified and specific DEGs were obtained by excluding overlapping DEGs with the control group.

RNA sequencing provides insights into the toxicogenomic response of ZF4 cells to methyl methanesulfonate.

Whole genome transcriptomic studies are powerful for characterizing the molecular mechanisms underlying the physiological effects of chemicals, and are informative for environmental health risk assessment. Alkylating agents are an abundant class of chemicals that can damage DNA in the environment, and are used for anticancer treatments. Currently, little is known regarding the molecular mechanisms of toxic alkylating agents in zebrafish cell lines.

Investigation of effect of 17α-ethinylestradiol on vigilin expression using an isolated recombinant antibody.

Vigilin, a highly conserved protein from yeast to mammals, is a multifunctional protein in eukaryotic organisms. One biological function of vigilin is to stabilize the expression level of vitellogenin (VTG). This study aimed to develop vigilin as a new estrogen-inducible biomarker that correlates with the widely applied estrogen-inducible biomarker VTG and expand the ability to detect it in various species.

Distribution of vitellogenin in zebrafish (Danio rerio) tissues for biomarker analysis.

Vitellogenin (VTG), the precursor of yolk proteins, is a sensitive biomarker of estrogenic contamination in aquatic environments. Traditionally, VTG was believed to be synthesized under the control of estrogen in the livers of mature females and then secreted into the blood, before being taken up by the ovaries and cleaved into lipovitellin and phosvitin, which provide nutrition for developing embryos. However, recent studies have reported that the liver is not the only tissue to express VTG and this has led to questions over the precise tissue distribution of VTG in zebrafish.

Antigenic analysis of grass carp reovirus using single-chain variable fragment antibody against IgM from Ctenopharyngodon idella.

Grass carp (Ctenopharyngodon idella) is an important species of freshwater aquaculture fish in China. However, grass carp reovirus (GCRV) can cause fatal hemorrhagic disease in yearling populations. Until now, a strategy to define the antigenic capacity of the virus's structural proteins for preparing an effective vaccine has not been available.

[Freezing-thawing damages plasma membrane integrity of goat spermatozoa].

Objective: To evaluate the plasma membrane integrity and morphology of fresh and frozen goat spermatozoa.

Methods: The ejaculates of three male goats were obtained by the artificial vagina method of collection and the rates of sperm abnormality and acrosome integrity were detected after freezing-thawing processing. The plasma membrane integrity of the fresh and frozen-thawed goat spermatozoa was evaluated with a combination of fluorescent probes, carboxyfluorescein diacetate and propidium iodide.
