Abstract
Molecular simulation has been widely used to study microbial proteins' structural composition and dynamic properties, such as volatility, flexibility, and stability at the microscopic scale. Herein, this review describes the key elements of molecular docking and molecular dynamics (MD) simulations in molecular simulation; reviews the techniques combined with molecular simulation, such as crystallography, spectroscopy, molecular biology, and machine learning, to validate simulation results and bridge information gaps in the structure, microenvironmental changes, expression mechanisms, and intensity quantification; illustrates the application of molecular simulation, in characterizing the molecular mechanisms of interaction of microbial proteins with four different types of contaminants, namely heavy metals (HMs), pesticides, dyes and emerging contaminants (ECs). Finally, the review outlines the important role of molecular simulations in the study of microbial proteins for controlling environmental contamination and provides ideas for the application of molecular simulation in screening microbial proteins and incorporating targeted mutagenesis to obtain more effective contaminant control proteins.

J Mol Graph Model 2023; 124:108567. [PMID: 37481883 DOI: 10.1016/j.jmgm.2023.108567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 06/30/2023] [Accepted: 07/12/2023] [Indexed: 07/25/2023]
Abstract
Phosphodiesterase-4, the primary enzyme responsible for cAMP degradation in the majority of immune and inflammatory cells, plays a critical role in the regulation of intracellular cAMP levels. Consequently, small molecular entities capable of inhibiting PDE4 have been employed in the treatment of inflammation-associated disorders, such as chronic obstructive pulmonary disease (COPD), psoriasis, atopic dermatitis (AD), inflammatory bowel diseases (IBD), rheumatic arthritis (RA). In the present investigation, a multi-faceted approach was employed to identify novel PDE4 inhibitors, utilizing the co-crystallization structure of PDE4B available in the Protein Data Bank (PDB) database, drug-like screening, false positive filtration, similarity and ADMET screen, as well as molecular docking via multiple software platforms, in conjunction with bioactivity assays. A thiazol-3-propanamides derivative, designated MR9, was discovered to inhibit PDE4B activity with IC50 values of 2.12 μM and suppress cellular inflammatory factor TNF-α release with an EC50 value of 3.587 μM. These findings suggest that the innovative active scaffold of MR9 offers a promising foundation for further structural refinement aimed at developing more potent PDE4 inhibitors.

Viewpoints on the Role of Transient Receptor Potential Melastatin Channels in Cardiovascular System and Disease: A Systematic Review. Curr Probl Cardiol 2023; 48:101012.

Abstract
Transient receptor potential (TRP) family play critical roles in cardiovascular system. TRPM family as largest TRP subfamily is non-voltage Ca2+-activated selective channels which has 8 members. This study aimed to discuss the role of TRPM family in cardiovascular system and diseases. Systematic search was performed covering PubMed, ISI Web of Science, and Google Scholar from inception until June 2021 using related keywords and Mesh terms for English studies with human, animal and in-vitro subjects. Finally 10 studies were selected for data extraction. Reviewing the articles showed that TRPM2, TRPM4, TRPM5, TRPM6 and TRPM7 play important roles in cardiovascular system and diseases. TRPM2 could be activated by reactive oxygen species (ROS) and effects on cardiac injury and cardiac fibrosis. TRPM7 and TRPM6 also have been reported to be associated with cardiac fibrosis and atrial fibrosis development respectively. TRPM4 channels contributed to resting membrane potential of cerebral artery smooth muscle cells and atrial contraction. TRPM5 channels are bitter taste sensors and prevent high salt intake and consequently high blood pressure due to the high salt intake. In conclusion based on the proof of the effectiveness of some members of TRPM family in the cardiovascular system, research on other members of this channel group seems to be useful and necessary to find their possible connection to the cardiovascular system.

Zhou F, Yang L, Yang L, Wang X, Guo N, Sun W, Ma H. Trpc5-regulated AMPKα/mTOR autophagy pathway is associated with glucose metabolism disorders in low birth weight mice under overnutrition. Biochem Biophys Res Commun 2022; 630:1-7. [PMID: 36122525 DOI: 10.1016/j.bbrc.2022.09.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 09/06/2022] [Accepted: 09/10/2022] [Indexed: 11/19/2022]
Abstract
Previous studies have shown that low birth weight (LBW) individuals are at higher risk of glucose metabolism disorders compared with normal birth weight (NBW) individuals under overnutrition conditions, but the mechanism remains unclear. To explore the underlying mechanism of glucose metabolism disorders induced by LBW under overnutrition in adulthood, the prenatal malnutrition method was applied to ICR mice to establish the LBW mice model and high-fat diets were used to mimic overnutrition conditions. Then the mechanism was further explored on Hepg2 cells treated with nutritional deprivation plus palmitic acid. The results showed that LBW plus high-fat interventions will cause glucose metabolism disorders and inhibit autophagy flux in adulthood. Moreover, the expression of TRPC5-regulated AMPK/mTOR autophagy pathway was downregulated by LBW with high-fat interventions. Collectively, LBW plus high-fat intervention increased the risk of glucose metabolism disorders, which may be related to the alteration of TRPC5 expression level and its regulation of the AMPKα/mTOR autophagy pathway. This study may provide a fundamental basis for the molecular mechanism of glucose metabolism disorders induced by LBW with high-fat diets in adulthood and a new target for the treatment of metabolic diseases in LBW individuals.
