This study was undertaken to observe the effects and possible mechanism of CC chemokine ligand 5 (CCL5) on invasion, proliferation and percentage of CD44+/CD24- subpopulation of human breast cancer line MCF-7 and to investigate the correlation of expression levels of CCL5 and its receptors with the progression of breast cancer. We used real-time RT-PCR to(More)
Clinical inhibitors Darunavir (DRV) and Amprenavir (APV) are less effective on HIV-2 protease (PR2) than on HIV-1 protease (PR1). To identify molecular basis associated with the lower inhibition, molecular dynamics (MD) simulations and molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) calculations were performed to investigate the effectiveness(More)
The molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) method combined with molecular dynamics (MD) simulations were used to investigate the functional role of protonation in human immunodeficiency virus type 1 (HIV-1) protease complexed with the inhibitor BEA369. Our results demonstrate that protonation of two aspartic acids (Asp25/Asp25') has a(More)
