Pathway network of pyroptosis and its potential inhibitors in acute kidney injury.

Acute kidney injury (AKI) is a worldwide problem, and there is no effective drug to eliminate AKI. The death of renal cells is an important pathological basis of intrinsic AKI. At present, targeted therapy for TEC death is a research hotspot in AKI therapy.

RIG-I, a novel DAMPs sensor for myoglobin activates NF-κB/caspase-3 signaling in CS-AKI model.

Background: Acute kidney injury (AKI) is the main life-threatening complication of crush syndrome (CS), and myoglobin is accepted as the main pathogenic factor. The pattern recognition receptor retinoicacid-inducible gene I (RIG-I) has been reported to exert anti-viral effects function in the innate immune response. However, it is not clear whether RIG-I plays a role in CS-AKI.

Using Spin-Coated Silver Nanoparticles/Zinc Oxide Thin Films to Improve the Efficiency of GaInP/(In)GaAs/Ge Solar Cells.

We synthesized a silver nanoparticle/zinc oxide (Ag NP/ZnO) thin film by using spin-coating technology. The treatment solution for Ag NP/ZnO thin film deposition contained zinc acetate (Zn(CH₃COO)₂), sodium hydroxide (NaOH), and silver nitrate (AgNO₃) aqueous solutions. The crystalline characteristics, surface morphology, content of elements, and reflectivity of the Ag NPs/ZnO thin film at various concentrations of the AgNO₃ aqueous solution were investigated using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, atomic force microscopy, and ultraviolet⁻visible⁻near infrared spectrophotometry.

Combined intranasal nerve growth factor and ventricle neural stem cell grafts prolong survival and improve disease outcome in amyotrophic lateral sclerosis transgenic mice.

Amyotrophic lateral sclerosis (ALS) is a fatal disease that selectively involves motor neurons. Neurotrophic factor supplementation and neural stem cell (NSC) alternative therapy have been used to treat ALS. The two approaches can affect each other in their pathways of action, and there is a possibility for synergism.

Association analysis of USF1 gene polymorphisms and total unstable carotid plaque area in atherosclerotic stroke patients.

Polymorphisms of the upstream stimulatory factor 1 (USF1) have been associated with carotid artery intima-media thickness and coronary atherosclerotic lesions. Unstable carotid plaque is an atherosclerotic change of vascular morphology that has been correlated with cerebrovascular ischemic symptoms. Associations of three single nucleotide polymorphisms of the USF1 gene with total unstable carotid plaque area (CPA) were investigated in Chinese atherosclerotic stroke patients.

[Protein expression, purification of PCGF1 and its monoclonal antibody preparation and identification].

Aim: To express the human recombinant PCGF1 protein and prepare monoclonal antibody (mAb) against it.

Methods: The recombinant expression plasmid pET32a-His-PCGF1-128/189 was made and transformed into E.coli (BL21), and then the recombinant fusion protein His-PCGF1-128/189 was expressed and purified.

Downstream of tyrosine kinase/docking protein 6, as a novel substrate of tropomyosin-related kinase C receptor, is involved in neurotrophin 3-mediated neurite outgrowth in mouse cortex neurons.

Background: The downstream of tyrosine kinase/docking protein (Dok) adaptor protein family has seven members, Dok1 to Dok7, that act as substrates of multiple receptor tyrosine kinase and non-receptor tyrosine kinase. The tropomyosin-related kinase (Trk) receptor family, which has three members (TrkA, TrkB and TrkC), are receptor tyrosine kinases that play pivotal roles in many stages of nervous system development, such as differentiation, migration, axon and dendrite projection and neuron patterning. Upon related neurotrophin growth factor stimulation, dimerisation and autophosphorylation of Trk receptors can occur, recruiting adaptor proteins to mediate signal transduction.

Identification of differentially expressed microRNAs by microarray: a possible role for microRNAs gene in medulloblastomas.

Background: MicroRNAs (miRNAs) are small noncoding regulatory RNAs whose aberrant expression may be observed in many malignancies. However, few data are yet available on human primary medulloblastomas. This work aimed to identify that whether miRNAs would be aberrantly expressed in tumor tissues compared with non-tumorous cerebellum tissues from same patients, and to explore a possible role during carcinogenesis.

MiRE: a graphical R package for microRNA-related analysis.

Objective: To provide a set of useful analysis tools for the researchers to explore the microRNA data.

Methods: The R language was used for generating the Graphical Users Interface and implementing most functions. Some Practical Extraction and Report Language (Perl) scripts were used for parsing source files.

[Effect of NECL1 on the proliferation of T98G glioma cell line].

Objective: To study the regulation role of tumor suppressor NECL1 on the proliferation of glioma cell line.

Methods: We detected the expression level of NECL1 in human normal brain tissue and glioma cell lines using semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blot. T98G cell line in which NECL1 was silent and whose transfection efficiency was relatively high as target cell was chosen, and the effect of NECL1 on the proliferation of T98G cell line in vitro was detected by using cell growth curve, flow cytometry, and Hoechst staining.

[Role of cell adhesion molecules Necl1 in synaptogenesis in primary cultured rat neurons].

Objective: To study the role of cell adhesion molecules Necl1 in synaptogenesis in primary cultured neurons.

Methods: Semi-quantitive reverse transcription polymerase chain reaction (RT-PCR) was used to detect the expression pattern of Necl1 in the neuronal differentiation cell model in vitro. Western blot was performed to detect the expression pattern of Necl1 in primary cultured rat neurons and in purified synaptosome.

[MiR-9 regulates the expression of CBX7 in human glioma].

Objective: To detect the expression of CBX7 in human glioma and investigate the potential regulatory effect of abnormally expressed microRNAs on CBX7 expression.

Methods: Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blot were applied to detect the expression pattern of CBX7 in 2 human normal brain tissues, 9 glioma tissues, and 3 glioma cell lines. Miranda algorithm and Ensemble Machine Learning algorithm were combined to predict miRNAs that target human CBX7.

[Bioluminescent imaging monitoring of a anti-angiogenesis therapeutic gene vasostatin in tumor cell PC3].

Objective: To generate a sensitive tool for noninvasive monitoring of a therapeutic gene vasostatin.

Methods: We fused the bioluminescent reporter gene firefly luciferase to the therapeutic transgene vasostatin and ensured that these two proteins would not interrupt each other and kept their own natural character.

Results: We therefore examined clones of PC3 cells stably expressing fusion gene and positive controlfluc with bioluminescence.
