Volume-regulated anion channels participate in the cellular response to osmotic swelling. These membrane proteins are heteromers of LRRC8 family members whose composition determines permeation properties. Although structures of the obligatory LRRC8A subunit have previously defined the architecture o...

This experiment explored the impact of cell volume increase and regulatory volume decrease (RVD) on the transcriptome of mouse macrophages. Bone marrow-derived macrophages (BMDMs) were isolated from CX3CR1-cre LRRC8A-flox, or littermate wild-type (CX3CR1-cre negative, LRRC8A flox) mice (PMID: 33216...
To investigate the biological function of LRRC8A and its underlying molecular mechanisms, we performed high-throughput sequencing to analyze the gene expression profiles of control and LRRC8A-knockdown cells.
Regulation of cell volume is essential for tissue homeostasis and cell viability. In response to hypertonic stress, cells need rapid electrolyte influx to compensate water loss and to prevent cell death in a process known as regulatory volume increase (RVI). However, the molecular component able to ...
