Genome Res. 2022 Jul 20;32(7):1271-84. doi: 10.1101/gr.276192.121. Online ahead of print. Genome Res. 2022. PMID: 35858751
Then, focusing on IPA isoforms that are up-regulated by doxorubicin in the cytosol and highly translated (up-regulated and/or abundant in polysomes), we identify several IPA isoforms that promote cell survival to doxorubicin. Mechanistically, by using an original ap …

Ribonuclease activity is enhanced in cytoplasmic extracts of HCT116 (p53+/+) cells exposed to gamma-irradiation or treated by the non-genotoxic drug AS101 but decreased following treatment by genotoxic (e.g., doxorubicin) or non-genotoxic (e.g., DFMO) agents, thus indicati …

We therefore determined the action of H19 in three different human hepatoma cell lines (HepG2, Plc/Prf5, and Huh7). Clonogenicity and proliferation assays showed that H19 overexpression could suppress tumor cell survival and proliferation after treatment with either sorafe …

Intestinal epithelial HuR modulates distinct pathways of proliferation and apoptosis and attenuates small intestinal and colonic tumor development.
Giammanco A, Blanc V, Montenegro G, Klos C, Xie Y, Kennedy S, Luo J, Chang SH, Hla T, Nalbantoglu I, Dharmarajan S, Davidson NO. Giammanco A, et al. Cancer Res. 2014 Sep 15;74(18):5322-35. doi: 10.1158/0008-5472.CAN-14-0726. Epub 2014 Aug 1. Cancer Res. 2014. PMID: 25085247 Free PMC article.
In this study, we explored the impact of conditional, tissue-specific genetic deletion of HuR on intestinal growth and tumorigenesis in mice. Mice lacking intestinal expression of HuR (Hur (IKO) mice) displayed reduced levels of cell proliferation in the smal …

Translational control of TOP2A influences doxorubicin efficacy.
Srikantan S, Abdelmohsen K, Lee EK, Tominaga K, Subaran SS, Kuwano Y, Kulshrestha R, Panchakshari R, Kim HH, Yang X, Martindale JL, Marasa BS, Kim MM, Wersto RP, Indig FE, Chowdhury D, Gorospe M. Srikantan S, et al. Mol Cell Biol. 2011 Sep;31(18):3790-801. doi: 10.1128/MCB.05639-11. Epub 2011 Jul 18. Mol Cell Biol. 2011. PMID: 21768308 Free PMC article.
Using a novel MS2-tagged RNA precipitation method, we identified microRNA miR-548c-3p as a mediator of these effects and further uncovered that the interaction of miR-548c-3p with the TOP2A 3'UTR repressed TOP2A translation by antagonizing the action of HuR. Lowering TOP2A …

Inhibiting cytoplasmic accumulation of HuR synergizes genotoxic agents in urothelial carcinoma of the bladder.
Guo J, Lv J, Chang S, Chen Z, Lu W, Xu C, Liu M, Pang X. Guo J, et al. Oncotarget. 2016 Jul 19;7(29):45249-45262. doi: 10.18632/oncotarget.9932. Oncotarget. 2016. PMID: 27303922 Free PMC article.
Here we show that HuR is required for the efficacy of chemotherapies in urothelial carcinoma of the bladder. We identify pyrvinium pamoate, an FDA-approved anthelminthic drug, as a novel HuR inhibitor that dose-dependently inhibited cytoplasmic accumulation of Hu …
