The Relationship

ABSTRACT Helicobacter pylori infection performs a key role in gastric tumorigenesis. Long non-coding RNAs (lncRNAs) have demonstrated a great potential to be regarded as effective malignancy biomarkers for various gastrointestinal diseases including gastric cancer (GC). The present review highlights the relationship between lncRNAs and H. pylori in GC. Several studies have examined not only the involvement of lncRNAs in H. pylori-associated GC progression but also their molecular mechanisms of action. Among the pertinent studies, some have addressed the effects of H. pylori infection on modulatory networks of lncRNAs, while others have evaluated the effects of changes in the expression level of lncRNAs in H. pylori-associated gastric diseases, especially GC. The relationship between lncRNAs and H. pylori was found to be modulated by various molecular pathways.

Transcriptional Landscape

Blood malignancies often arise from undifferentiated hematopoietic stem cells or partially differentiated stem-like cells. A tight balance of multipotency and differentiation, cell division, and quiescence underlying normal hematopoiesis requires a special program governed by the transcriptional machinery. Acquisition of drug resistance by tumor cells also involves reprogramming of their transcriptional landscape. Limiting tumor cell plasticity by disabling reprogramming of the gene transcription is a promising strategy for improvement of treatment outcomes. Herein, we review the molecular mechanisms of action of transcription-targeted drugs in hematological malignancies (largely in leukemia) with particular respect to the results of clinical trials.

AbstractSARS-CoV-2 is a new human coronavirus (CoV), which emerged in China in late 2019 and is responsible for the global COVID-19 pandemic that caused more than 97 million infections and 2 million deaths in 12 months. Understanding the origin of this virus is an important issue, and it is necessary to determine the mechanisms of viral dissemination in order to contain future epidemics. Based on phylogenetic inferences, sequence analysis and structure–function relationships of coronavirus proteins, informed by the knowledge currently available on the virus, we discuss the different scenarios on the origin—natural or synthetic—of the virus. The data currently available are not sufficient to firmly assert whether SARS-CoV2 results from a zoonotic emergence or from an accidental escape of a laboratory strain. This question needs to be solved because it has important consequences on the risk/benefit balance of our interactions with ecosystems, on intensive breeding of wild and domestic animals, on some laboratory practices and on scientific policy and biosafety regulations. Regardless of COVID-19 origin, studying the evolution of the molecular mechanisms involved in the emergence of pandemic viruses is essential to develop therapeutic and vaccine strategies and to prevent future zoonoses. This article is a translation and update of a French article published in Médecine/Sciences, August/September 2020 (10.1051/medsci/2020123).

Objective: This review sought to bring evidence of studies addressing the mechanisms of action of topiramate in the prevention and treatment of migraine. Background: Migraine is a neurovascular disorder that affects a large part of the world population. The use of prophylactics contributes to the decrease in the frequency and severity of this disease. Among the antiepileptic drugs, the topiramate, has proven to be the most effective for the treatment of migraine. Although the mechanism of action of this drug is still not well elucidated in the literature, there are several molecular mechanisms proposed. Methodology: A survey was carried out in the literature, from February to March 2018, in different databases, using the descriptors: topiramate, migraine and mechanisms of action. After a careful selection, 25 manuscripts were chosen for this review. Results: Evidence from a number of studies has indicated that the main mechanisms of action of topiramate are related to the modulation of voltage-dependent sodium and calcium ion channels, blockade of excitatory glutamate transmission and inhibition by gamma-aminobutyric acid receptors (GABA), AMPA/kainate and some isoenzymes of carbonic anhydrase. In addition, topiramate is involved in the suppression of cortical spreading depression, besides influencing trigeminovascular activity, and neuronal excitability. Conclusion: Thus, topiramate could be involved in the prevention of major events of the pathophysiology of migraine. Acting directly on cortical spreading depression (DAC), trigeminovascular signals and decreased central sensitization of migraine pain.
