Effect of Bioplastic Material on Adhesion, Growth, and Proliferative Activity of Human Fibroblasts When Incubated in Solutions Mimic the Acidity of Wound an Acute and Chronic Inflammation.

Introduction: One of the key stages of wound healing is the phase of inflammation, which is a transitional process between hemostasis and wound healing. Each stage of the inflammatory-reparative process is characterized by its own value of the acidity of the wound bed. For example, in the acute stage of inflammation, the acidity of the medium in the wound bed decreases to pH 5.

[Low level laser therapy: molecular mechanisms of anti-inflammatory and regenerative effects].

Unlabelled: Laser therapy as a physiotherapeutic method has been successfully used for a long time in the treatment of various pathologies, but the action mechanisms of low level laser therapy (LLLT) remain understudied.

Objective: To perform the analysis of published results of LLLT investigations, to describe the physical principles of photobiomodulation, its action mechanisms on various cells and tissues, therapeutic intervention and efficiency of the technique.

Material And Methods: The search of articles was done for the period from 2014 to 2022.

MeCP2 Represses the Rate of Transcriptional Initiation of Highly Methylated Long Genes.

Mutations in the methyl-DNA-binding repressor protein MeCP2 cause the devastating neurodevelopmental disorder Rett syndrome. It has been challenging to understand how MeCP2 regulates transcription because MeCP2 binds broadly across the genome and MeCP2 mutations are associated with widespread small-magnitude changes in neuronal gene expression. We demonstrate here that MeCP2 represses nascent RNA transcription of highly methylated long genes in the brain through its interaction with the NCoR co-repressor complex.

Early-Life Gene Expression in Neurons Modulates Lasting Epigenetic States.

In mammals, the environment plays a critical role in promoting the final steps in neuronal development during the early postnatal period. While epigenetic factors are thought to contribute to this process, the underlying molecular mechanisms remain poorly understood. Here, we show that in the brain during early life, the DNA methyltransferase DNMT3A transiently binds across transcribed regions of lowly expressed genes, and its binding specifies the pattern of DNA methylation at CA sequences (mCA) within these genes.

Generating stable cell lines with quantifiable protein production using CRISPR/Cas9-mediated knock-in.

Cell lines expressing foreign genes have been widely used to produce a variety of recombinant proteins. However, generating recombinant protein-expressing cell lines is usually a lengthy process and the resulting protein expression levels are often inconsistent. Here, we describe an efficient method for making stable cell lines expressing any recombinant protein of interest in a controllable and quantifiable manner.
