SMIM30 is localized to the membranes of the endoplasmic reticulum and mitochondria, where it functions to modulate intracellular calcium dynamics. By enhancing the activity of the sarco/endoplasmic reticulum calcium ATPase (SERCA), SMIM30 reduces cytosolic calcium levels. This reduction triggers an upregulation in cell cycle regulators (CDK4, cyclin E2, phosphorylated-Rb, and E2F1), thereby promoting the G1/S phase transition and accelerating cell proliferation. Functionally, silencing of SMIM30 leads to decreased growth of hepatoma cells in vitro as well as reduced tumor formation in xenograft models and chemically induced hepatoma, confirming its critical role in HCC progression."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Yanan Pang, Zhiyong Liu, Huan Han, et al.
