Recent News

Nuclear TARBP2 as a regulator of RNA stability

September 5th, 2019

In our most recent paper, we have reported the functional dissection of a previously unknown pathway of RNA decay. This study was a follow-up to our discvoery of TARBP2 as a promoter of breast cancer metastasis (see here). In this collaborative work, we systematically dissected the molecular mechanism through which TARBP2 regulates the expression and stability of its target regulon. Based on our model, TARBP2 binds target pre-mRNAs co-transcriptionally and recruits the RNA methylation machinery to add m6A marks. RNA methylation, in turn, influences the binding patterns of splicing factors such as SRSF1 and diminishes efficient splicing of introns. Through its interaction with components of the nuclear surveillance machinery, TARBP2 delivers these mis-spliced products to the exosome complex for degradation. Finally, we also showed that TARBP2 not only promotes breast cancer metastasis, but also acts as an oncogene in lung cancer cells. See our published work here.

Introducing Orphan Non-coding RNAs (oncRNAs)

November 5th, 2018

We have recently annotated a new class of small RNAs, which we have named oncRNAs. These are largely absent in normal cells but emerge in cancer cells as a result of cellular transformation. We have demonstrated that cancer cells can "adopt" these orphan RNAs to carry out new functions relevant to the progression of the disease. Another benefit of oncRNAs became apparent once we realized that a large fraction of oncRNAs are released by cancer cells in exosomes. We think that since every tumor can be assigned a digital oncRNA barcode, i.e. a profile of oncRNA presence/absence, finding evidence of this barcode outside the cell can point to the existence of an underlying cancer cell from which these RNAs originate. You can read the paper in November's issue of Nature Medicine. You can also read a new release by UCSF on our work.

tRNAs as global regulators of gene expression

June 7th, 2016

Transfer-RNAs are tranditionally viewed as a static component of the protein synthesis machinery. Recently, several studies have raised the possibility that tRNAs are more dynamic and can support different cellular states and phenotypes. Although generally debated, some evidence has emerged that tRNA levels in the cell imapct the gene expression landscape in the cell. In a recent study, we demonstrated that the tRNA landscape is drastically modified in highly metastatic cells and that these modulations drive the expression of key promoters of metastasis. These results were published in Cell. You can also read a short preview about this study.

m6A-Dependent Nuclear Processing of RNA

September 10th, 2015

Nucleotide modifications can expand the information content of nucleic acids. The majority of these chemical modifications are largely uncharacterized. The most common base modification of eukaryotic mRNA is methylation of the N6 nitrogen on adenosine referred to (m6A). In two recent papers, we have described the role of m6A RNA modification as a marker for RNA processing. We showed that RNA-binding protein HNRNPA2B1 can preferentially bind this modification and impact miRNA processing and splicing. These results were published in Nature and Cell. You can also read a short blog post about this study.

Endogenous tRNA-Derived Fragments Suppress Breast Cancer Progression

May 7th, 2015

Cells respond to stress through a variety of mechanisms. In this study, we identified a mechanistically novel post-transcriptional regulatory pathways that protects the cells from pathologic growth and spread. We showed that a novel class of tRNA fragments (tRFs) that are generated under stress in normal and poorly metastatic cells, evade induction in highly metastatic cells. Using mechsnitic in vitro and in vivo experiments, we demonstrated that the oncogenic RNA-binding protein YBX1 is titrated by these fragments, which in turn reduces the expression of the YBX1 regulon. These results were published in the journal Cell and highlighted in Nature Reviews Cancer.

TARBP2 promotes breast cancer metastasis

July 9th, 2014

Aberrant regulation of RNA stability has an important role in many disease states. Whole-genome transcript stability measurements in poorly metastatic and highly metastatic breast cancer cells paved the way for the identification of a structural RNA element the presence of which results in higher decay rate in metastatic cells. We subsequently identified the dsRBP TARBP2 as the interacting partner and showed that this RNA-binding protein plays a functional role in promoting breast cancer metastasis. Focused computational and experimental follow-ups revealed that TARBP2 mediates metastasis through destabilization of novel tumor suppressors, ZNF395 and APP. The results were published in Nature (2014). We also published an invited editorial feature in Cell cycle journal based on this study. Our work was also highlighted by the editors at Nature Cancer Reviews.

Conserved Post-transcriptional Regulatory Elements

April 10th, 2014

Gene expression is highly regulated in order to achieve the requisite repertoire of RNA and protein products across the vast space of possible cellular phenotypes encompassing physiological and developmental contingencies. Five years ago, we embarked on a path to catalog the sequences in RNA that play substantial regulatory roles, by providing linear or structural information for trans factors to recognize and act on. We used a library of conserved 3'UTR sequences, synthesized on a custom-designed Agilent microarray and cloned in a dual-reporter system, to measure their impact on gene expression in a controled setting. Our results were recently published in Cell Reports. To learn more, you can read a short synopsis of our work here.

Structural element discovery in RNA

April 8th, 2012

Decoding post-transcriptional regulatory programs in RNA is a critical step towards the larger goal of developing predictive dynamical models of cellular behaviour. The vast landscape of RNA regulatory elements remains largely uncharacterized. We recently described a computational framework based on context-free grammars and mutual information that systematically explores the immense space of small structural elements and reveals motifs that are significantly informative of genome-wide measurements of RNA behaviour. TEISER (tool for eliciting informative structural elements in RNA), which marks our first successful attempt to reveal structural regulatory elements that underlie transcript stability in vivo was recently published. This study was published in the May 10th (2012) issue of Nature. TEISER can be downloaded here. A limited version has also been integrated into iGET for public use.
