Atf6alpha Impacts Cell Number By Influencing Survival, Death And Proliferation, Rohit B. Sharma, Jarin T. Snyder, Laura C. Alonso

Open Access Articles

BACKGROUND: A growing body of literature suggests the cell-intrinsic activity of Atf6alpha during ER stress responses has implications for tissue cell number during growth and development, as well as in adult biology and tumorigenesis [1]. This concept is important, linking the cellular processes of secretory protein synthesis and endoplasmic reticulum stress response with functional tissue capacity and organ size. However, the field contains conflicting observations, especially notable in secretory cell types like the pancreatic beta cell.

SCOPE OF REVIEW: Here we summarize current knowledge of the basic biology of Atf6alpha, along with the pleiotropic roles Atf6alpha plays in cell life ...
