The gene is highly polymorphic, causing large interindividual variability in the metabolism of several clinically important drugs. The authors investigated the diversity and distribution of alleles in Indians using whole genome sequences (N = 1518). Functional consequences were assessed using pathogenicity scores and molecular dynamics simulations. The analysis revealed population-specific alleles (, , , , , ) and remarkable differences in variant and phenotype frequencies with global populations. The authors observed that one in three Indians could benefit from a dose alteration for psychiatric drugs with accurate phenotyping. Molecular dynamics simulations revealed large conformational fluctuations, confirming the predicted reduced function of and alleles. The findings emphasize the utility of comprehensive profiling for aiding precision public health.

Background: Duchenne muscular dystrophy (DMD) is a prevalent, fatal degenerative muscle disease with no effective treatments. Mdx mouse model of DMD exhibits impaired muscle performance, oxidative stress, and dysfunctional autophagy. Although antioxidant treatments may improve the mdx phenotype, the precise molecular mechanisms remain unclear.

Background: Spinal cord injury (SCI) triggers a complex inflammatory response that impedes neural repair and functional recovery. The modulation of macrophage phenotypes is thus considered a promising therapeutic strategy to mitigate inflammation and promote regeneration.

Methods: We employed microarray and single-cell RNA sequencing (scRNA-seq) to investigate gene expression changes and immune cell dynamics in mice following crush injury at 3 and 7 days post-injury (dpi).

DNP (3,4-dinitropyrazole) has attracted much interest due to its promising melting characteristics and high detonation performances, such as low melting point, high density, high detonation velocity, and low sensitivity. In this work, first-principles molecular dynamics (MD) simulations were performed to investigate the anisotropic shock response of DNP in conjunction with the multiscale shock technique (MSST). The initial decomposition mechanism was revealed through the evolution of the chemical reaction and product analysis.

We present two innovative approaches to investigate the dynamics of membrane fusion and the strength of protein-membrane interactions. The first approach employs pore-spanning membranes (PSMs), which allow for the observation of protein-assisted fusion processes. The second approach utilizes colloidal probe microscopy with membrane-coated probes with reconstituted proteins.

Steered Molecular Dynamics (SMD) simulation is a powerful computational simulation technique that enables the controlled manipulation of molecular systems by applying external forces. This method is frequently utilized to investigate the slow processes of biomolecular systems that occur within sub-second to second time scales, achieved through SMD simulations that only span nanoseconds. SMD simulation can be utilized to study the detailed mechanism of protein conformational changes, protein unfolding, and ligand dissociation, etc.
