The Transcriptome of Type I Murine Astrocytes under Interferon-Gamma Exposure and Remyelination Stimulus
Molecules. 2017. Vol. 22. No. 5. P. E808.
Astrocytes are considered to be an important contributor to central nervous system (CNS) disorders, particularly multiple sclerosis. The transcriptome of these cells is greatly affected by cytokines released by lymphocytes, penetrating the blood–brain barrier—in particular, the classical pro-inflammatory cytokine interferon-gamma (IFNγ). We report here the transcriptomal profiling of astrocytes treated using IFNγ and benztropine, a putative remyelinization agent. Our findings indicate that the expression of genes involved in antigen processing and presentation in astrocytes are significantly upregulated upon IFNγ exposure, emphasizing the critical role of this cytokine in the redirection of immune response towards self-antigens. Data reported herein support previous observations that the IFNγ-induced JAK-STAT signaling pathway may be regarded as a valuable target for pharmaceutical interventions.

In our work the dynamics of brain-derived neurotrophic factor expression and neuroprotective effects of Semax were investigated for the focal ischemia and focal ischemia with carotid artery reperfusion. BDNF mRNA expression dynamics is complex: BDNF reduced in the injured hemisphere at 3 and 7 hours after ischemia and increased expression of BDNF in the intact ...

Gemcitabine, a first-line chemotherapeutic agent for bladder cancer (BC), often loses clinical efficacy due
to the development of drug resistance, the underlying mechanisms of which remain poorly understood. In
this work, a highly gemcitabine-resistant RT112/GR cell line was obtained by long-term selection. The MTT
assay revealed a 9312-fold decrease in gemcitabine sensitivity and moderate resistance to cisplatin (2.60-fold,

MicroRNA (miRNA) genes are frequently located in close proximity within the genome, forming so-called clusters. These clusters are transcribed as polycistronic units, suggesting coordinated transcriptional regulation of the miRNAs they contain. However, individual mature miRNAs from the same cluster often accumulate at varying levels and exhibit distinct tissue-specific expression patterns, indicating the presence of regulatory ...

Involvement of the transcription factor Bach1 in various scenarios of cellular regulation is reviewed herein. To date, the most extensively studied role of Bach1 is that of a repressor of the antioxidant genetic program initiated by the Nrf2 factor. This program counteracts oxidative stress, which triggers both ferroptosis and the intrinsic apoptotic pathway. Bach1 functions unrelated ...

Quasi-movements (QMs), which are movement attempts minimized to the point of movement extinction, evoke EEG patterns similar to those of real movement. QMs can model attempted movement in healthy subjects and are therefore of interest as an alternative to motor imagery (MI) in rehabilitation brain–computer interfaces (BCIs), in which the attempted movement of the paralyzed ...

Understanding the earliest pathological changes in Alzheimer disease (AD) is critical for improving early intervention strategies. However, the relationship between amyloid plaque characteristics and early behavioral and molecular alterations remains unclear. We used 6-month-old female APPswe/PS1dE9 mice, a model of early amyloid-dominant pathology, to assess cognition and emotionality across a battery of behavioral tests. Amyloid ...

Antiviral activity is commonly summarized using endpoint measures such as EC50 or EC90, yet these quantities emerge from a dynamic biological system and depend on viral replication kinetics, host-cell properties, experimental design, and the assay used to quantify infection. Infectious-virus titers, viral RNA, infected-cell fractions, viability measurements, and immune readouts capture different components of the ...

Low-frequency vibrations play an essential role in biomolecular processes involving DNA such as gene expression, charge transfer, drug intercalation, and DNA–protein recognition. However, understanding the vibrational basis of these mechanisms relies on theoretical models due to the lack of experimental evidence. Here we present the low-frequency vibrational spectra of G-quadruplexes (structures formed by four strands ...

Preeclampsia (PE) is a severe obstetric complication caused by chronic placental ischaemia. Genome-wide profiling of microRNA isoforms in two trophoblast hypoxia models (CoCl2 and the oxyquinoline derivative neuradapt, BeWo b30 cells) and clinical PE samples (placental tissue, syncytiotrophoblast vesicles) revealed concordant downregulation of hsa-miR-143-3p isoforms. Under a strict fold-change threshold, the canonical isoform (21 nt) ...

Background. Preeclampsia (PE) complicates 2–8% of pregnancies and involves placental hypoxia and HIF-pathway activation, especially in early-onset PE (eoPE). Chemical mimetics like cobalt(II) chloride (CoCl2) and oxyquinoline derivatives model trophoblast hypoxia in vitro, yet their fidelity in recapitulating PE gene profiles remains unclear. Integrating patient tissue analyses with experimental models may reveal common markers and ...

It was recently found that the primary transcripts of some microRNA genes (pri-miRNAs) are able to express peptides with 12 to 40 residues in length. These peptides, called miPEPs, participate in the transcriptional regulation of their own pri-miRNAs. In our previous studies, we used bioinformatic approach for comparative analysis of pri-miRNA sequences in plant genomes ...
