Epigenetic Silencing of CDR1as Drives IGF2BP3-Mediated Melanoma Invasion and Metastasis.
2018
Summary Metastasis is the primary cause of death of cancer patients. Dissecting mechanisms governing metastatic spread may uncover important tumor biology and/or yield promising therapeutic insights. Here, we investigated the role of circular RNAs (circRNA) in metastasis, using melanoma as a model aggressive tumor. We identified silencing of cerebellar degeneration-related 1 antisense (CDR1as), a regulator of miR-7, as a hallmark of melanoma progression. CDR1as depletion results from epigenetic silencing of LINC00632, its originating long non-coding RNA (lncRNA) and promotes invasion in vitro and metastasis in vivo through a miR-7-independent, IGF2BP3-mediated mechanism. Moreover, CDR1as le…
Abstract PR04: Epigenetic silencing of CDR1as drives IGF2BP3-mediated melanoma invasion and metastasis
2020
Abstract Metastasis is the primary cause of death of cancer patients. Dissecting mechanisms governing metastatic spread may uncover new biology and/or yield promising therapeutic insights. Here we investigated the role of circular RNAs (circRNAs), a class of noncoding RNAs lacking characterized functions, in metastasis, using melanoma as a model aggressive tumor. We analyzed RNA-seq of melanocytes and melanoma short-term cultures to characterize the landscape of circRNA in melanocytic cells. We observed silencing of Cerebellar Degeneration Related 1 (CDR1as), a neuronal-enriched circRNA and known regulator of the microRNA miR-7, in melanoma cell lines and short-term cultures compared to cul…
Mutations in PRDM15 Are a Novel Cause of Galloway-Mowat Syndrome
2021
Background Galloway-Mowat syndrome (GAMOS) is characterized by neurodevelopmental defects and a progressive nephropathy, which typically manifests as steroid-resistant nephrotic syndrome. The prognosis of GAMOS is poor, and the majority of children progress to renal failure. The discovery of monogenic causes of GAMOS has uncovered molecular pathways involved in the pathogenesis of disease. Methods Homozygosity mapping, whole-exome sequencing, and linkage analysis were used to identify mutations in four families with a GAMOS-like phenotype, and high-throughput PCR technology was applied to 91 individuals with GAMOS and 816 individuals with isolated nephrotic syndrome. In vitro and in vivo st…
