High interstitial fluid pressure enhances USP1-dependent KIF11 protein stability to promote hepatocellular carcinoma progression.

Background: HCC is characterized by a high interstitial fluid pressure (HIFP) environment, which appears to support cancer cell survival. However, the mechanisms behind this phenomenon are not fully understood.

Methods: This study investigates the role of kinesin family member 11 (KIF11) in HCC under HIFP conditions, using both in vivo and in vitro models.

PSMD11 promotes the proliferation of hepatocellular carcinoma by regulating the ubiquitination degradation of CDK4.

The 26S proteasome non-ATPase regulatory subunit 11 is a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins, and PSMD11 plays a key role in the regulation of embryonic stem cell proteasome activity. However, the role of PSMD11 in hepatocellular carcinoma has not been studied. In this study, it was found that the expression of PSMD11 in HCC tissues was significantly higher than that in para-cancerous tissues, and was associated with poor prognosis.
