Exploring the impact of intraspecific interaction between sibling colonies of Bacillus cereus MSM-S1 in the absence and presence of antibiotics

This study examines how sibling colonies of Bacillus cereus MSM-S1 interact under antibiotic and non-antibiotic conditions, revealing changes in morphology, sporulation, and gene expression.

Association of miR-181a-5p with Lantana camara leaf extract-mediated inhibition of proliferation, survival, and migration in luminal A-type MCF-7 cells and triple-negative type MDA-MB-231 cells

This study shows that Lantana camara leaf extract increases miR-181a-5p expression, which reduces proliferation, survival, and migration of breast cancer cells by targeting BCL-2, MCL-1, and CDKN3.

Lantana camara leaf extract-mediated suppression of DNA methyltransferase 1 promotes G0/G1 cell cycle arrest and apoptosis, and impedes migration in MDA-MB-231 triple-negative breast cancer cells

This study shows that Lantana camara leaf extract suppresses DNMT1, leading to tumor suppressor gene reactivation, G0/G1 arrest, apoptosis, and reduced migration in TNBC cells.

Antimicrobial and Biofilm-Inhibitory Potential of Green Synthesized Silver Nanoparticles from Lantana camara against Pseudomonas aeruginosa

This study evaluates the antibacterial and antibiofilm effects of green-synthesized silver nanoparticles from Lantana camara against Pseudomonas aeruginosa, showing disruption of biofilm and quorum-sensing inhibition.

Salt-induced reduction of hyperswarming motility in Bacillus cereus MHS is associated with reduced flagellation, reduced nanotube formation and reduction in expression of quorum sensing regulator

This study shows that NaCl reduces swarming motility in Bacillus cereus MHS by decreasing flagellation, nanotube formation, and quorum sensing regulator expression.

Differentiating the mechanism of antibacterial activities of nano and ionic copper by using Escherichia coli as a model microorganism

This study compares the antibacterial mechanisms of nano and ionic copper using Escherichia coli, finding differences in their effectiveness and cellular impact.
