Abstract
Progesterone receptor membrane component 1 (PGRMC1) is a pleiotropic protein over-expressed in lung adenocarcinoma (LUAD). The precise molecular mechanisms underlying the signature motif of Casein kinase (CK2) presence in PGRMC1 and their role in LUAD remain unclear. X-ray crystallographic structure for CK2 and PGRMC1 from the PubChem database was obtained and subjected to protein-protein interaction (PPI) analysis to identify their interactions. In addition, the CK2 inhibitor - Silmitasertib was also utilised to understand the interaction between PGRMC1-CK2. The PPI complex (PGRMC1-CK2) and the PPI-ligand interaction analysis and their Molecular Dynamics (MD) studies revealed the stability of their interactions and critical amino acid contacts within the 5Ǻ vicinity of the CK2 signature motif "T/S-x-x-E/D". Moreover, in-vitro colony formation assay, migration assay, and gene expression analysis using quantitative Real-time PCR revealed that Silmitasertib (IC50-2.5 μM) was highly influential in suppressing the PGRMC1-CK2 expression axis. In conclusion, our study infers that PGRMC1-CK-2 axis inhibition could be a potential therapeutic option to limit the promotion and progression of lung cancer.
期刊介绍:
Drug Research (formerly Arzneimittelforschung) is an international peer-reviewed journal with expedited processing times presenting the very latest research results related to novel and established drug molecules and the evaluation of new drug development. A key focus of the publication is translational medicine and the application of biological discoveries in the development of drugs for use in the clinical environment. Articles and experimental data from across the field of drug research address not only the issue of drug discovery, but also the mathematical and statistical methods for evaluating results from industrial investigations and clinical trials. Publishing twelve times a year, Drug Research includes original research articles as well as reviews, commentaries and short communications in the following areas: analytics applied to clinical trials chemistry and biochemistry clinical and experimental pharmacology drug interactions efficacy testing pharmacodynamics pharmacokinetics teratology toxicology.
