Myofibroblast-derived exosomes enhance macrophages to myofibroblasts transition and kidney fibrosis.

A critical event in the pathogenesis of kidney fibrosis is the transition of macrophages into myofibroblasts (MMT). Exosomes play an important role in crosstalk among cells in the kidney and the development of renal fibrosis. However, the role of myofibroblast-derived exosomes in the process of MMT and renal fibrosis progression remains unknown.

Fostering idealogical and polical education via knowledge graph and KNN model: an emphasis on positive psychology.

As the primary domain of ideological and political education in higher education institutions, ideological and political courses must align with principles rooted in human psychology and education. Integrating educational psychology into ideological and political teaching in universities enhances the scientific, targeted, and forward-thinking nature of such education. The burgeoning exploration of knowledge graph applications has extended to machine translation, semantic search, and intelligent question answering.

Remimazolam attenuates inflammation and kidney fibrosis following folic acid injury.

The transition of acute kidney injury (AKI) to chronic kidney disease (CKD) is characterized by intense inflammation and progressive fibrosis. Remimazolam is widely used for procedural sedation in intensive care units, such as AKI patients. Remimazolam has been shown to possess anti-inflammatory and organ-protective properties.

Protein-protein interactions between RUNX3 and ZEB1 in chronic lung injury induced by methamphetamine abuse.

Methamphetamine (MA) is the most common and highly addictive substance abuse drug. Runt-related transcription factor 3 (RUNX3) and Zinc finger E-box-binding homeobox 1 (ZEB1) are associated with lung inflammation and fibrosis. However, the protein-protein interactions (PPIs) between RUNX3 and ZEB1 and its involvement in MA-induced chronic lung injury is still unclear.

Discovery of small-molecule activators of nicotinamide phosphoribosyltransferase (NAMPT) and their preclinical neuroprotective activity.

The decline of nicotinamide adenine dinucleotide (NAD) occurs in a variety of human pathologies including neurodegeneration. NAD-boosting agents can provide neuroprotective benefits. Here, we report the discovery and development of a class of potent activators (NATs) of nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in the NAD salvage pathway.

LncRNA BLACAT1 Promotes Proliferation, Migration and Invasion of Prostate Cancer Cells via Regulating miR-29a-3p/DVL3 Axis.

Background: Long non-coding RNA bladder cancer associated transcript 1 (BLACAT1) is oncogenic in several types of cancers. However, little is known concerning its expression and function in prostate cancer.

Methods: Paired prostate cancer samples were collected, and the expression levels of BLACAT1, miR-29a-3p and disheveled segment polarity protein 3 (DVL3) were examined by quantitative real-time polymerase chain reaction (qRT-PCR); BLACAT1 shRNAs were transfected into PC-3 and LNCaP cell lines, and proliferative ability was detected by cell counting kit-8 (CCK-8) assay; qRT-PCR and Western blot were used to analyze the changes of miR-29a-3p and DVL3; dual-luciferase reporter gene assay was used to determine the regulatory relationships between miR-29a-3p and BLACAT1, and miR-29a-3p and DVL3.

MicroRNA-151 regulates the growth, chemosensitivity and metastasis of human prostate cancer cells by targeting PI3K/AKT.

Purpose: Prostate cancer causes significant mortality and microRNAs (miRs) have been shown to regulate the growth and metastasis of different cancers. In this context, the present study was designed to investigate the potential of miR-151 in the treatment of prostate cancer.

Methods: The normal and the prostate cancer cell lines (LNCaP, PC-3 and Du-145) were used in this study.

Acquisition of functional neurons by direct conversion: Switching the developmental clock directly.

Identifying approaches for treating neurodegeneration is a thorny task but is important for a growing number of patients. Researchers have focused on discovering the underlying molecular mechanisms of reprogramming and optimizing the technologies for acquiring neurons. Direct conversion is one of the most important processes for treating neurological disorders.

Efficacy and Safety of Microsurgical Subinguinal Varicocelectomy with and without Testicular Delivery for Varicocele Patients: A Systematic Review and Meta-Analysis.

Purpose: This study reviewed the efficacy and safety of the microsurgical subinguinal varicocelectomy (MSV) with and without testicular delivery (TD) for varicocele patients.

Materials And Methods: A systematic literature search was conducted in EMBASE, PubMed, MEDLINE, Cochrane databases, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), and Google Scholar databases to identify relevant studies that reported MSV with and without TD for varicocele patients published in English or Chinese up to October 2018. The Newcastle-Ottawa Scale (NOS) and the Jadad scores were used to evaluate the methodological quality of all the included studies.

Tet3-Mediated DNA Demethylation Contributes to the Direct Conversion of Fibroblast to Functional Neuron.

The direct conversion of somatic cells to neurons by bypassing the multipotent cell state may be a powerful approach for personalized medicine. In addition to neuronal transcription factors and multiple small molecules, we find that epigenetic modification also contributes to the direct conversion of fibroblasts to neurons. Here, we show that Tet3, a DNA dioxygenase, can rapidly and efficiently convert fibroblasts directly into functional neurons.

Conversion of Fibroblasts to Parvalbumin Neurons by One Transcription Factor, Ascl1, and the Chemical Compound Forskolin.

Abnormalities in parvalbumin (PV)-expressing interneurons cause neurodevelopmental disorders such as epilepsy, autism, and schizophrenia. Unlike other types of neurons that can be efficiently differentiated from pluripotent stem cells, PV neurons were minimally generated using a conventional differentiation strategy. In this study we developed an adenovirus-based transdifferentiation strategy that incorporates an additional chemical compound for the efficient generation of induced PV (iPV) neurons.
