Twinfilin regulates breast cancer cell invasion and interleukin-11 expression through the miR-206/ MKL1/SRF pathway

ABSTRACT: Recent studies have implicated genes that control actin cytoskeleton dynamics as important regulators in cellular invasion, a critical step in metastasis. Many of their downstream pathways still remain to be discovered. MicroRNAs have emerged as important epigenetics regulators of important cellular processes and aid in the identification of pathways involved in breast cancer progression and metastasis. In this study, we characterized the miR-206 downstream pathway specifically its direct target, Twinfilin (TWF1), a g-actin regulator and their downstream target, interleukin-11 (IL-11). We determined that miR-206 and TWF1 regulate IL-11 expression through the mycocardian-related transcription factor (MRTF-A or MKL1) and serum response factor (SRF) complex. Identification of this novel pathway that regulates breast cancer invasion will aid in the understanding of metastasis and development of new treatment strategies.

miR-206 modulates the pathogenesis of muscular dystrophy of mdx mice

Project description:In response to skeletal muscle injury, adult myogenic stem cells, known as satellite cells, are activated and undergo proliferation and differentiation to regenerate new muscle fibers. The skeletal muscle-specific microRNA, miR-206, is up-regulated in satellite cells following muscle injury, but its role in muscle regeneration has not been defined. Here we show that skeletal muscle regeneration in response to cardiotoxin injury is impaired in mice lacking miR-206. Loss of miR-206 also accelerates and exacerbates the dystrophic phenotype of mdx mice, a model for Duchenne muscular dystrophy. MiR-206 promotes satellite cell differentiation and fusion to form multinucleated myofibers by suppressing a collection of negative regulators of myogenesis. Our findings reveal an essential role for miR-206 in satellite cell differentiation during skeletal muscle regeneration and as a modulator of Duchenne muscular dystrophy.

The invadopodial and cytoskeletal regulator glycine- and cysteine-rich protein 2 induces pro-metastatic matrix metalloproteinase expression in breast cancer cells

Project description:Actin cytoskeleton has multiple functions in cancer cell invasion and metastasis; yet how these functions are coordinated remains unclear. In the cytoplasm, actin is necessary for the formation of specialized membrane protrusions, termed invadopodia, that concentrate and secrete extracellular matrix-degrading enzymes, particularly the matrix metalloproteinases (MMPs), facilitating tumor cell invasion. We recently identified cysteine- and glycine-rich protein 2 (CRP2) as an actin-crosslinking protein whose activity is required for the assembly and elongation of the invadopodium actin backbone. Here, we report that CRP2 is also located in the nucleus of breast cancer cells to induce a complementary pro-metastasis gene expression program mostly related to breast cancer cell invasion and metastasis. We showed in this present study that CRP2 interacts with the transcription factors SRF and GATA3 to regulated the expression of MMP-9 and MMP-13 respectively. Overall, our data indicate that CRP2 act a key mediator of tumor cell invasion.

L-plastin Ser5 phosphorylation via RSKs, downstream effectors of the MAPK/ERK pathway, in (breast) cancer cells (and in vitro)

Project description:Deregulated cell migration and invasion, which are hallmarks of metastatic cancer cells, are correlated to structural and functional alterations of the actin cytoskeleton associated to a large panel of actin-binding proteins. Among these, the actin-bundling protein L-plastin, initially detected in leukocytes, is ectopically expressed in several solid tumours and is often considered as a metastatic marker. Phosphorylation of L-plastin on residue serine 5 (Ser5) has been shown to activate L-plastin and to be crucial for invasion and metastasis formation. Here, we investigate the signalling pathway leading to L-plastin Ser5 phosphorylation in four breast cancer cell lines. Whole genome microarray analysis comparing cell lines with different invasive capacities and corresponding L-plastin Ser5 phosphorylation levels revealed that genes of the MAPK/ERK pathway are differentially expressed. In line, in vitro kinase assays showed that MAPK/ERK pathway downstream kinases RSK1 and RSK2 are able to directly phosphorylate L-plastin on Ser5. In parallel to a knockdown approach, activation and inhibition studies of signalling molecules of the MAPK/ERK pathway, followed by computational modelling analysis, confirmed that RSK is an important activator of L-plastin in all four studied cell lines. Finally and rounding up our study, RSK knockdown significantly impaired migratory and invasive capacities of a selected invasive cell line, thus consolidating RSK as a promising therapeutic target in certain invasive carcinomas. Altogether, our data provide substantial evidence that the MAPK/ERK pathway is involved in L-plastin Ser5 phosphorylation in breast cancer cells with its downstream kinases RSK1 and RSK2 being able to directly phosphorylate L-plastin on Ser5.
