Cancer progression accompanies broad dysregulations in the splicing landscape of the cell. Building on our earlier work on RNA structural elements, we have now discovered a previously unknown structured element that is associated with increased exon inclusion. We revealed that SNRPA1, a core component of the spliceosome, moonlights as a regualtor of RNA splicing via its interactions with these elements. We also showed that SNRPA1, which is up-regulated in highly metastatic cells, acts as a driver of breast cancer metastasis by modulating isoform levels for specific target genes. Morpholino-based reversal of SNRPA1-mediated changes converts the cell into a less malignant state. Our results, now published in Science, also demonstrates the utility of hybrid computational/experimental platforms as potent engines of discovery. For a lay description of this study, see the write up by Jeff Norris puiblished here.
AACR and MPM Oncology Charitable Foundation announced three grants to support transformative cancer research and our lab was one of the recipients. This funding mechanism is an innovative partnership between the American Association for Cancer Research (AACR) and the UBS Oncology Impact Fund (OIF) managed by MPM Capital. With support from this grant, we will expand on our research on the role of our newly discovered orpan non-coding RNAs to serve as building blocks for cancer-engineered regulatory programs.
With widespread societal and economical devastation, the new coronovirus pandemic has deeply reshaped our approach to life and how we do science. The heterogeneity of patient response to this virus remains a baffling mystery that complicates clinical response. Age was determined as a clear risk factor; however, it was soon discovered that risk of mortality from this infection is substantially higher in men. Recently, members of the Fattahi lab carried out a systematic in vitro screening of stem-cell derived cardiomyocites to identify regulators of ACE2 expression, an enzyme that acts as the receptor for SARS-CoV-2. We levergaed this valuable screen to train a deep learning model that is capable of large-scale in silico screens to identify other compounds that can target ACE2 expression. Systematic analyses of these hit compounds revealed Andregen signaling as a key pathway involved in ACE2 expression. Confirmatory analyses in the UK Biobank dataset revealed a consistent association between androgen levels and COVID-19 risk. This work is published as a research article in Cell Stem Cell and an eariler manuscript describing these results was published as a preprint. You can also read an interview with Dr. Faranak Fattahi putting some of these findings in context.
Identifying master regulators that drive pathological gene expression is a key challenge in precision oncology. Here, we have developed an analytical framework, named PRADA, that identifies oncogenic RNA-binding proteins through the systematic detection of coordinated changes in their target regulons. Application of this approach to data collected from clinical samples, patient-derived xenografts, and cell line models of colon cancer metastasis revealed the RNA-binding protein RBMS1 as a suppressor of colon cancer progression. We observed that silencing RBMS1 results in increased metastatic capacity in xenograft mouse models, and that restoring its expression blunts metastatic liver colonization. We have found that RBMS1 functions as a post-transcriptional regulator of RNA stability by directly binding its target mRNAs. Together, our findings establish a role for RBMS1 as a previously unknown regulator of RNA stability and as a suppressor of colon cancer metastasis with clinical utility for risk stratification of patients. We recently reported these findings in the journal Cancer Discovery. You can also read the commentary graciously written by Dr. Hannah Carter for this work in the same issue.
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.
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.

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.
