Cadmium promotes the binding and centrosomal translocation of CCDC85C and PLK4 via ROS-GCLM pathway to trigger centrosome amplification in colon cancer cells.

Cadmium (Cd) is a prevalent heavy metal contaminant that can cause centrosome amplification (CA) and cancer. Since CA can initiate tumorigenesis, it is plausible that cadmium initiates tumorigenesis via CA. The present study investigated the signaling pathways underlying CA by Cd.

Advanced glycation end products initiate the mutual promoting cycle between centrosome amplification and the release of inflammatory cytokines in human vascular endothelial cells.

Inflammation is implicated in the development of diabetic complications including vascular pathology. Centrosome is known to play a role in cell secretion. We have reported that diabetes can trigger centrosome amplification (CA).

Hexavalent chromium causes centrosome amplification by inhibiting the binding between TMOD2 and NPM2.

Background: Hexavalent chromium can promote centrosome amplification (CA) as well as tumorigenesis. Since CA can lead to tumorigenesis, it is plausible that the chromium promotes the development of cancer via CA. In the present study, we investigated the signaling pathways of the chromium-induced CA.

The novel antitumor compound clinopodiside A induces cytotoxicity autophagy mediated by the signaling of BLK and RasGRP2 in T24 bladder cancer cells.

In the study, we investigated the anti-cancer effect of clinopodiside A and the underlying mechanisms using T24 bladder cancer cells as an experimental model. We found that the compound inhibited the growth of the bladder cancer cells and in a in a concentration- and dose-dependent manner, respectively, which showed a combinational effect when used together with cisplatin. In the bladder cancer cells, clinopodiside A caused autophagy, which was mediated by the signaling of BLK and RasGRP2, independently.

Centrosome amplification in cancer and cancer-associated human diseases.

Accumulated evidence from genetically modified cell and animal models indicates that centrosome amplification (CA) can initiate tumorigenesis with metastatic potential and enhance cell invasion. Multiple human diseases are associated with CA and carcinogenesis as well as metastasis, including infection with oncogenic viruses, type 2 diabetes, toxicosis by environmental pollution and inflammatory disease. In this review, we summarize (1) the evidence for the roles of CA in tumorigenesis and tumor cell invasion; (2) the association between diseases and carcinogenesis as well as metastasis; (3) the current knowledge of CA in the diseases; and (4) the signaling pathways of CA.
