Nuclear HuR accumulation through phosphorylation by Cdk1 (2008)

Kim, Hyeon Ho, Abdelmohsen, Kotb, Lal, Ashish, Pullmann, Rudolf, Yang, Xiaoling, Galban, Stefanie, ...

A predominantly nuclear RNA-binding protein, HuR translocates to the cytoplasm in response to stress and proliferative signals, where it stabilizes or modulates the translation of target mRNAs. Here,...

Upregulation of Isoflavonoids and Soluble Proteins in Edible Legumes by Light and Fungal Elicitor Treatments (2003)

Lal, Ashish, Warber, Sara, Kirakosyan, Ara, Kaufman, Peter B., Duke, James A.

Objective: In this study, our working hypothesis was that continuous light and fungal elicitation treatment of legume seedlings would lead to enhanced levels of isoflavonoids and soluble proteins....

Identification of a target RNA motif for RNA-binding protein HuR

De Silanes, Isabel López, Zhan, Ming, Lal, Ashish, Yang, Xiaoling, Gorospe, Myriam

HuR, a protein that binds to specific mRNA subsets, is increasingly recognized as a pivotal posttranscriptional regulator of gene expression. Here, HuR was immunoprecipitated under conditions that...

Concurrent versus individual binding of HuR and AUF1 to common labile target mRNAs

Lal, Ashish, Mazan-Mamczarz, Krystyna, Kawai, Tomoko, Yang, Xiaoling, Martindale, Jennifer L, Gorospe, Myriam

RNA-binding proteins HuR and AUF1 bind to many common AU-rich target mRNAs and exert opposing influence on target mRNA stability, but the functional interactions between HuR and AUF1 have not been...

Antiapoptotic function of RNA-binding protein HuR effected through prothymosin α

Lal, Ashish, Kawai, Tomoko, Yang, Xiaoling, Mazan-Mamczarz, Krystyna, Gorospe, Myriam

We report the antiapoptotic effect of RNA-binding protein HuR, a critical regulator of the post-transcriptional fate of target transcripts. Among the most prominent mRNAs complexing with HuR is that...

Clean western blot signals from immunoprecipitated samples

Lal, Ashish, Haynes, Susan R., Gorospe, Myriam

We present a strategy that overcomes the high background arising during Western blotting (WB) detection of proteins obtained through immunoprecipitation (IP). Traditional HRP-conjugated secondary...

Translational Repression by RNA-Binding Protein TIAR†

Mazan-Mamczarz, Krystyna, Lal, Ashish, Martindale, Jennifer L., Kawai, Tomoko, Gorospe, Myriam

The RNA-binding protein TIAR has been proposed to inhibit protein synthesis transiently by promoting the formation of translationally silent stress granules. Here, we report the selective binding of...

Translational Control of Cytochrome c by RNA-Binding Proteins TIA-1 and HuR

Kawai, Tomoko, Lal, Ashish, Yang, Xiaoling, Galban, Stefanie, Mazan-Mamczarz, Krystyna, Gorospe, Myriam

Stresses affecting the endoplasmic reticulum (ER) globally modulate gene expression patterns by altering posttranscriptional processes such as translation. Here, we use tunicamycin (Tn) to...
