Chmp1A (Chromatin modifying protein 1A/Charged multivesicular protein 1A) is a member of the ESCRT-III (Endosomal Sorting Complex Required for Transport) family, which mediates trafficking via MVB (multivesicular body) formation and sorting. Our studies suggest that Chmp1A is a novel tumor suppressor, especially in the pancreas. Knockdown of Chmp1A resulted in an increase of anchorage-independent growth of HEK 293T cells. Moreover, we showed that Chmp1A depleted HEK 293T cells forms tumor in xenograft mice. Knockdown of Chmp1A in PanC-1 cells promoted cell growth. In contrast, Doxycycline induced over-expression of Chmp1A in pancreatic cancer cells (PanC-1) resulted in cell growth inhibition, tumor …
