[HTML][HTML] Competing endogenous RNAs, non-coding RNAs and diseases: an intertwined story

U Ala - Cells, 2020 - mdpi.com
MicroRNAs (miRNAs), a class of small non-coding RNA molecules, are responsible for RNA
silencing and post-transcriptional regulation of gene expression. They can mediate a fine-…

[HTML][HTML] Coding-independent regulation of the tumor suppressor PTEN by competing endogenous mRNAs

Y Tay, L Kats, L Salmena, D Weiss, SM Tan, U Ala… - Cell, 2011 - cell.com
Here, we demonstrate that protein-coding RNA transcripts can crosstalk by competing for
common microRNAs, with microRNA response elements as the foundation of this interaction. …

A PML–PPAR-δ pathway for fatty acid oxidation regulates hematopoietic stem cell maintenance

K Ito, A Carracedo, D Weiss, F Arai, U Ala, DE Avigan… - Nature medicine, 2012 - nature.com
Stem-cell function is an exquisitely regulated process. Thus far, the contribution of metabolic
cues to stem-cell function has not been well understood. Here we identify a previously …

[HTML][HTML] In vivo identification of tumor-suppressive PTEN ceRNAs in an oncogenic BRAF-induced mouse model of melanoma

FA Karreth, Y Tay, D Perna, U Ala, SM Tan, AG Rust… - Cell, 2011 - cell.com
We recently proposed that competitive endogenous RNAs (ceRNAs) sequester microRNAs
to regulate mRNA transcripts containing common microRNA recognition elements (MREs). …

[HTML][HTML] MicroRNA-antagonism regulates breast cancer stemness and metastasis via TET-family-dependent chromatin remodeling

SJ Song, L Poliseno, MS Song, U Ala, K Webster, C Ng… - Cell, 2013 - cell.com
Tumor cells metastasize to distant organs through genetic and epigenetic alterations,
including changes in microRNA (miR) expression. Here we find miR-22 triggers epithelial-…

[HTML][HTML] The oncogenic microRNA miR-22 targets the TET2 tumor suppressor to promote hematopoietic stem cell self-renewal and transformation

SJ Song, K Ito, U Ala, L Kats, K Webster, SM Sun… - Cell stem cell, 2013 - cell.com
MicroRNAs are frequently deregulated in cancer. Here we show that miR-22 is upregulated
in myelodysplastic syndrome (MDS) and leukemia and its aberrant expression correlates …

Integrated transcriptional and competitive endogenous RNA networks are cross-regulated in permissive molecular environments

U Ala, FA Karreth, C Bosia, A Pagnani, R Taulli… - Proceedings of the …, 2013 - pnas.org
Competitive endogenous (ce)RNAs cross-regulate each other through sequestration of
shared microRNAs and form complex regulatory networks based on their microRNA signature. …

The BRAF pseudogene functions as a competitive endogenous RNA and induces lymphoma in vivo

…, V Léopold, M Sjoberg, TM Keane, A Verma, U Ala… - Cell, 2015 - cell.com
Research over the past decade has suggested important roles for pseudogenes in physiology
and disease. In vitro experiments demonstrated that pseudogenes contribute to cell …

RNA-binding protein transcripts as potential biomarkers for detecting Primary Sclerosing Cholangitis and for predicting its progression to Cholangiocarcinoma

U Ala, S Fagoonee - Frontiers in Molecular Biosciences, 2024 - frontiersin.org
Primary Sclerosing Cholangitis (PSC) is a persistent inflammatory liver condition that affects
the bile ducts and is commonly diagnosed in young individuals. Despite efforts to …

Hypomethylation of smoking-related genes is associated with future lung cancer in four prospective cohorts

…, A Naccarati, M Chadeau-Hyam, U Ala… - Nature …, 2015 - nature.com
DNA hypomethylation in certain genes is associated with tobacco exposure but it is
unknown whether these methylation changes translate into increased lung cancer risk. In an …
