Intrauterine desensitization enables long term survival of human oligodendrocyte progenitor cells without immunosuppression.

Immune rejection can be reduced using immunosuppressants which are not viable for premature infants. However, desensitization can induce immune tolerance for premature infants because of underdeveloped immune system. The fetuses of Wistar rats at 15-17 days gestation were injected via hOPCs-1 into brain, muscles, and abdomen ex utero and then returned while the fetuses of control without injection.

Increasing the value of Phragmites australis straw in a sustainable integrated agriculture model (SIAM) comprising edible mushroom cultivation and spent mushroom substrate compost.

Because of the regular annual harvest, Phragmites australis used in wetland protection produces an abundance of straw, resulting in a large amount of straw waste. As a result, the extra straw should be used in a convenient and efficient manner. A comprehensive analysis of P.

Identifying Genes that Affect Differentiation of Human Neural Stem Cells and Myelination of Mature Oligodendrocytes.

Human neural stem cells (NSCs) are self-renewing, multipotent cells of the central nervous system (CNS). They are characterized by their ability to differentiate into a range of cells, including oligodendrocytes (OLs), neurons, and astrocytes, depending on exogenous stimuli. An efficient and easy directional differentiation method was developed for obtaining large quantities of high-quality of human OL progenitor cells (OPCs) and OLs from NSCs.

Transcriptome Analysis Reveals Candidate Genes Involved in Light-Induced Primordium Differentiation in .

, a highly valued edible fungus, is one of the major commercially cultivated mushrooms in China. The development of , especially during the stage of primordium differentiation, is easily affected by light. However, the molecular mechanism underlying the response of primordium differentiation to light remains unknown.

Transcriptomics Analysis of Primordium Formation in .

Primordium formation is an important stage preceding the growth and development of the fruiting body. However, the molecular mechanisms underlying primordium formation remain unclear. In the present study, comparative transcriptomics was performed between mature mycelia and primordium to analyze the transcriptional properties during primordium formation in .

Transplanted Human Oligodendrocyte Progenitor Cells Restore Neurobehavioral Deficits in a Rat Model of Preterm White Matter Injury.

Preterm white matter injury (PWMI) is a common brain injury and a leading cause of life-long neurological deficits in premature infants; however, no effective treatment is available yet. This study aimed to investigate the fate and effectiveness of transplanted human oligodendrocyte progenitor cells (hOPCs) in a rat model of PWMI. Hypoxia-ischemia was induced in rats at postnatal day 3, and hOPCs (6 × 10 cells/5 μL) were intracerebroventricularly transplanted at postnatal day 7.

Effect of the Forth and Fifth Zinc Finger Deletions of MTF-1 on the Expression of Metal Ion Metabolism Related Gene.

Metal response element binding transcription factor 1 (MTF-1) is one of the important regulatory proteins involved in the mediation of intracellular metal ion balance, which is zinc dependent. The changes of zinc finger effected its function. MTF-1 mutant 293T cell line was obtained by transferring the vector of MTF-1 4th or 5th mutant zinc finger into 293T cell line that knocked out MTF-1 gene.

Study on the Safety of Human Oligodendrocyte Precursor Cell Transplantation in Young Animals and Its Efficacy on Myelination.

Oligodendrocyte precursor cells (OPCs) can differentiate into myelinating oligodendrocytes during embryonic development, thereby representing an important potential source for myelin repair or regeneration. To the best of our knowledge, there are very few OPCs from human sources (human-derived OPCs [hOPCs]). In this study, we aimed to evaluate the safety and remyelination capacity of hOPCs developed in our laboratory, transplanted into the lateral ventricles of young animals.

[Optimization of cryopreservative method for human fetal brain neural stem cells-derived oligodendrocyte precursor cells].

Objective To explore the impact of various conditions during cryopreservation on the survival rate of oligodendrocyte precursor cells (OPCs) derived from human fetal neural stem cells. Methods We compared the cell viability of oligodendrocyte precursors harvested with or without digestion. Then we tested the impact of 3 factors during cryopreservation, freezing solutions (solution with 70 mL/L DMSO and 930 mL/L FBS; solution with 70 mL/L DMSO, 300 mL/L FBS and OPC culture medium; solution with 70 mL/L DMSO, 300 mL/L FBS, 0.

Upregulated miRNA-182-5p expression in tumor tissue and peripheral blood samples from patients with non-small cell lung cancer is associated with downregulated Caspase 2 expression.

Lung cancer has the highest morbidity and mortality rates among all malignant tumors worldwide. Previous studies demonstrated that microRNA (miR)-182-5p may serve different roles in different types of cancer, including renal cell carcinoma and liver cancer. However, the functional role of miR-182-5p in non-small cell lung cancer (NSCLC) remains unknown.

Comparative transcriptomic analysis reveals molecular processes involved in pileus morphogenesis in Pleurotus eryngii under different light conditions.

Light plays an important role in pileus differentiation in Pleurotus eryngii cultivation, and pileus morphology is influenced by light quality. To understand the effects of light quality on pileus morphology at the transcriptional level, we performed a comparative transcriptomic analysis of pilei grown under blue and red light irradiation. We identified 3959 differentially expressed genes (DEGs) between the blue and red light-treated pilei, which included 1664 up-regulated and 2295 down-regulated genes.

A Comparative Transcriptome Analysis Reveals Physiological Maturation Properties of Mycelia in .

is a precious edible fungus with extremely high nutritive and medicinal value. The cultivation period of is longer than those of other species, which is mainly due to a longer mycelium physiological maturation period (30-60 days). Currently, the molecular processes underlying physiological maturation of the mycelium remain unclear.

Meta-Analysis of the SLCO1B1 c.521T>C Variant Reveals Slight Influence on the Lipid-Lowering Efficacy of Statins.

Background: Several studies have focused on the association between the lipid-lowering efficacy of statins and the SLCO1B1 c.521T>C polymorphism; however, the results are conflicting. The effects of statins show significant variability between individuals.

Balance between metallothionein and metal response element binding transcription factor 1 is mediated by zinc ions (review).

Metal ion homeostasis and heavy metal detoxification systems are regulated by certain genes associated with metal ion transport. Metallothionein (MT) and metal response element binding transcription factor 1 (MTF‑1) are important regulatory proteins involved in the mediation of intracellular metal ion balance. Differences in the zinc‑binding affinities of the zinc fingers of MTF‑1 and the α‑ and β‑domains of MT facilitate their regulation of Zn2+ concentration.

Risk assessment of mouse gastric tissue cancer induced by dichlorvos and dimethoate.

Cancer hazards from pesticide residues in food have been much discussed in the past decade. In this study, we showed that dichlorvos and dimethoate affect hemoglobin content and hematocrit value, but had no effect on red blood cell counts and total plasma protein in mice. A 40-mg/kg/day dose of dichlorvos upregulated the expression of , and genes in mouse gastric tissue.
