The mechanosensitive channel ELKIN1 regulates cellular adaptations to simulated microgravity.

ABSTRACT: In conditions of microgravity the human body undergoes extensive alterations in physiological function. However, it has proven challenging to determine how these changes are mediated at the molecular and cellular level. Here, we investigated whether ELKIN1, a mechanically activated ion channel, regulates changes in cellular and molecular structures in conditions of simulated microgravity. Deletion of ELKIN1 inhibited the simulated microgravity-induced alterations of cellular structure and attachment. In addition, cells lacking ELKIN1 did not exhibit changes in focal adhesion structures and redistribution of the YAP1 transcription factor in response to simulated microgravity, consistent with wild type cells. Finally, melanoma cell invasion of a collagen gel, from organotypic spheroids, was
