MeCP2 Differentially Regulate the Myelin MBP and PLP Protein Expression in Oligodendrocytes and C6 Glioma.

MeCP2 (methyl-CpG binding protein 2), an epigenetic regulator, has been shown to regulate the function of neurons and glial cells. Our previous study has demonstrated that MeCP2 repress the myelin gene expression in rat oligodendrocytes but whether MeCP2 bind to myelin gene MBP and PLP is not yet known. Besides oligodendrocytes, C6 glioma also expresses myelin genes and could be used as a model system to study myelin gene expression.

NLRX1 resides in mitochondrial RNA granules and regulates mitochondrial RNA processing and bioenergetic adaptation.

The role of mitochondria is emerging in regulation of innate immunity, inflammation and cell death beyond its primary role in energy metabolism. Mitochondria act as molecular platform for immune adaptor protein complexes, which participate in innate immune signaling. The mitochondrial localized immune adaptors are widely expressed in non-immune cells, however their role in regulation of mitochondrial function and metabolic adaption is not well understood.

MeCP2 in central nervous system glial cells: current updates.

avMethyl‑CpG binding protein 2 (MeCP2) is an epigenetic regulator, which preferentially binds to methylated CpG dinucleotides in DNA. MeCP2 mutations have been linked to Rett syndrome, a neurodevelopmental disorder characterized by severe intellectual disability in females. Earlier studies indicated that loss of MeCP2 function in neuronal cells was the sole cause of Rett syndrome.

Clinical implications of p53 alterations in oral cancer progression: a review from India.

p53 plays a central role in prevention of normal cell from the development of the malignant phenotype. Somatic alterations (mutations, loss of heterozygosity, deletions) in p53 are a hallmark of most human cancers and cause defects in normal p53 function. However, in the tumors harboring wild-type p53, there are alterations in the regulation of the p53.

Compounds 6a-f were designed based on 3-aminomethyl pyridine attached to different acetamide derivatives and in compounds 6g-h it was attached to coumarin moiety. Coumarin containing compounds 6g-h showed very poor anticancer activity against both A549 (Lungs cancer cell line), and MCF-7 (Breast cancer cell line) cell lines in MTT assay.

A new flatland buddy as toxic gas scavenger: A first principles study.

Recently predicted and grown new single element two dimensional (2D) material borophene gathered tremendous research interest due to its structural, electronic and other properties. Using first principles based dispersion corrected density functional calculations, we have studied interaction of two toxic gases phosgene (COCl) and carbon monoxide (CO) with borophene to understand the role of borophene as biosensor and carriers in drug delivery. The sensing behaviour of borophene towards COCl and CO has been studied by calculating the binding energy and electronic density of states (DOS).

Nucleobases-decorated boron nitride nanoribbons for electrochemical biosensing: a dispersion-corrected DFT study.

Understanding the interactions between biomolecules and boron nitride nanostructures is key for their use in nanobiotechnology and medical engineering. In this study, we investigated the adsorption of nucleobases adenine (A), guanine (G), cytosine (C), thymine (T) and uracil (U) over armchair and zigzag boron nitride nanoribbons (BNNR) using density functional theory to define the applicability of BNNR for the sensing of nucleobases and DNA sequencing. To appropriately account for dispersion, the van der Waals forces (DFT-D2)-type method developed by Grimme was also included in the calculations.

Exposure to sub-lethal dose of a combination insecticide during early embryogenesis influences the normal patterning of mesoderm resulting in incomplete closure of ventral body wall of chicks of domestic hen.

Pesticide exposure to the non target groups especially during embryonic development has quite often resulted in congenital malformations. A commercially available combination insecticide (Ci, 50% chlorpyrifos and 5% cypermethrin) is known to induce ventral body wall defects (VBWDs) wherein abdominal viscera protrude out of the ventral body wall. Herein, an attempt was made to understand the mechanistic insight into Ci induced VBWDs.

TiO nanoparticles induce omphalocele in chicken embryo by disrupting Wnt signaling pathway.

Titanium dioxide nanoparticles (TiO NPs) are among abundantly used metal oxide NPs but their interactions with biomolecules and subsequent embryonic toxicity in higher vertebrates is not extensively reported. Physicochemical interactions of TiO NPs with egg albumen reveals that lower doses of TiO NPs (10 and 25 µg/ml) accounted for higher friccohesity and activation energy but an increment in molecular radii was recorded at higher doses (50 and 100 µg/ml). FTIR analysis revealed conformational changes in secondary structure of egg albumen as a result of electrostratic interactions between egg albumen and TiO NPs.
