Unconventional prefoldin RPB5 interactor (URI), a RNA polymerase II Subunit 5-Interacting protein, is known to participate in the regulation of nutrient-sensitive mTOR-dependent transcription programs. Multiple studies have recently demonstrated that URI functions as an oncoprotein, possibly through the mTOR pathway, and regulates tumor cell motility, invasion, and metastasis. However, whether and how URI plays a role in gastric oncogenesis has not been elucidated. Due to drug resistance, recurrence and metastasis, the prognosis of gastric cancer remains poor. This study aims to explore the effects of URI on gastric cancer cells by focusing on their migratory ability and resistance to adriamycin. URI was over-expressed or knocked-down in MGC-803 and HGC-27 gastric cancer cells using URI plasmid or siRNA transfection approach. The cell viability, apoptosis, and migration ability were then examined by the CCK-8 assay, flow cytometer Annexin V/PI staining, and the Transwell cell migration assay respectively. The protein levels of apoptosis and EMT related genes were detected by western blot. The results showed that overexpression of URI promoted while knock-down of URI inhibited gastric cancer cell proliferation. URI overexpression resulted in increased Bcl-2 expression but decreased levels of Bax, cleaved PARP-1 and cleaved caspase-3. Conversely, cells treated with URI siRNA showed increased adriamycin induced apoptosis, along with reduced Bcl-2, but increased Bax, cleaved PARP-1 and cleaved caspase-3 expression. We have also shown that overexpression of URI enhanced cancer cell proliferation and migration with higher levels of Snail and Vimentin, whereas knockdown of URI in MGC-803 and HGC-27 cells inhibited proliferation and migration with decreased Snail and Vimentin expression. Together, our results support that URI promotes cell survival and mobility and acts as a chemotherapeutics resistant protein in MGC-803 and HGC-27 cells. URI might be a potential biomarker for gastric cancer diagnostics and prognostics.

Hepatocellular carcinoma (HCC) is one of the most difficult cancer disease for diagnosis and treatment, with a low survival rate and high recurrence rate and mortality. Nuclear factor of activated T-cells 5 (NFAT5) is mediated by osmolality and proved to be a carcinogenic gene in some tumor. However in our study we considered NFAT5 as tumor suppressor of HCC. RT-qPCR was performed for NFAT5 expression in tumor tissues. NaCl was applied to make hyperosmotic treatment. We knockdowned and overexpressed NFAT5 to investigate its role in HCC. FCM was used for apoptosis assay. Transwell and scratch assay is proceeded for invasion.NFAT5 is downregulated in HCC tissue and cell lines, besides, upregulated by hyperosmolality. NFAT5 promotes apoptosis by regulating PARP-1,BAX/BCL2 while inhibits invasion through EMT-related protein claudin-1 and fibronectin. Hyperosmolality is also a protective factor for HCC. We considered hyperosmolality exhibited his protective effect by inducing NFAT5.In a word, NFAT5 inhibits invasion and promotes apoptosis in HCC, associated with osmolality.
