Gramicidin A accumulates in mitochondria, reduces ATP levels, induces mitophagy, and inhibits cancer cell growth

Yun-Wei Xue et al.

Summary: Gramicidin A exhibits potent cytostatic activity in human breast cancer cells by disrupting ion concentration gradients of the plasma membrane and affecting mitochondrial function, ultimately leading to inhibition of cell growth.

Vectorial insertion of a β-helical peptide into membrane: a theoretical study on polytheonamide B

Mahroof Kalathingal et al.

Summary: This study investigates the dynamic mechanism of the vectorial insertion of polytheonamide B (pTB), a prefolded cytotoxic peptide. The all-atom molecular dynamics simulations reveal that the insertion of pTB involves three phases - landing, penetration, and equilibration, with an energy cost of 4.3 kcal/mol at the membrane surface. The membrane insertion of pTB can occur through either trapped or untrapped pathways, with membrane anchoring by the hydrophobic N-terminal blocking group playing a crucial role in the landing phase.
