Computational analysis of MYC gene variants: structural and functional impact of non-synonymous SNPs.

The MYC proto-oncogene encodes a basic helix-loop-helix leucine zipper (HLH-LZ) transcription factor, acting as a master regulator of genes involved in cellular proliferation, differentiation, and immune surveillance. Dysregulation of MYC is implicated in over 70% of human cancers, driving oncogenic processes through altered gene expression and disrupted cellular functions. Non-synonymous single nucleotide polymorphisms (nsSNPs) within coding regions can significantly impact protein structure and function, leading to abnormal cellular behaviours.

Tuning of a Hydrogen-Bonded Organic Framework by Liquid-Assisted Mechanosynthesis between Trans-Aconitic Acid and Isonicotinamide.

Cocrystallization of trans-aconitic acid (TACA) and isonicotinamide (INA) using liquid assisted mechanochemical grinding results in a unique supramolecular hydrogen-bonded organic framework (HOF) system encapsulating various organic solvents (liquid guest) with the formation of channel inclusion compounds. Dimension and shape of the framework is dependent on the solvent used during liquid assisted grinding (LAG). Although crystal structure of the cocrystal (TACA) ⋅ (INA) ⋅ (HO)@(INA) has been determined by Single Crystal X-ray diffraction (SCXRD), crystal structures of 3 cocrystal HOFs were determined by microcrystal electron diffraction (MicroED) and synchrotron X-ray diffraction due to lack of suitable single crystal.

In Situ Stabilization of Bi Nanoparticles into the Nanopores of Modified Montmorillonite: Efficient Heterogeneous Catalysts for Reduction of 4-Nitrophenol.

Here, we report the in situ generation of Bi nanoparticles (BiNPs) into a nanoporous matrix by impregnation of bismuth chloride and subsequent reduction with sodium borohydride. The nanoporous matrix was created by acid activation of natural montmorillonite clay under controlled conditions with the aim that it may serve as a host for BiNPs. The characterization of stabilized BiNPs was done by using Fourier-transform infrared (FTIR), powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), and field emission scanning electron microscopy-energy dispersive X-ray (FESEM-EDX) techniques.
