DUSP6 protein, human

DUSP6 (Dual Specificity Phosphatase 6) is a protein-coding gene that plays a crucial role in the regulation of cell signaling pathways.
This enzyme functions as a negative regulator of the MAPK/ERK (Mitogen-Activated Protein Kinase/Extracellular Signal-Regulated Kinase) signaling cascade, which is involved in cellular processes such as proliferation, differentiation, and survival.
DUSP6 specifically dephosphorylates and inactivates ERK1 and ERK2, thereby modulating the intensity and duration of ERK-mediated signaling.
Dysregulation of DUSP6 has been implicated in various disease conditions, including cancer, neurological disorders, and metabolic diseases.
Understanding the functions and regulation of DUSP6 is crucial for developing targeted therapies and improving disease management.

MPAS for each cell line, tumor, or patient sample was derived from expression data for 10 MAPK-specific genes (PHLDA1, SPRY2, SPRY4, DUSP4, DUSP6, CCND1, EPHA2, EPHA4, ETV4, and ETV5). Gene expression was measured using either RNA-Seq (Illumina, Hayward, CA, USA) sequencing (reads per counts per million)49 (link) or the MAPK-specific Nanostring panel (Supplementary Table 9). MPAS was computed as MAPK activity =  izn, where zi is the z-score of each gene’s expression level and n is the number of genes comprising the set (i.e., n= 10). For the Nanostring data, gene expression levels were normalized by sample, using a set of housekeeping genes, and across samples for the RNA-Seq data. The score is thus a relative metric of MAPK gene expression, the absolute values of which will depend on the assay characteristics and choice of normalization, in addition to the underlying biology. As such, MPAS values should be interpreted as relative to other samples within an experimental or clinical context.

A Dusp6 BAC clone was identified by PCR from BAC DNA pools as directed by manufacturers protocols (Genome Systems). A 10 Kb Kpn1 fragment was identified that contain parts of Exon 1 (441 bp) and approximately 9.5 Kb of upstream promoter sequence (see Figure 1A). This Kpn1 fragment was subcloned into the Kpn1 site of pSce1d2EGFP vector (pSce1 vector with d2EGFP cDNA cloned into the multiple cloning site). 20 pg of pDusp6:d2EGFP plasmid DNA was injected into the 1-cell embryo with I-Sce 1 (New England Biolabs, Ipswich, MA) restriction enzyme as described in [37 (link)]. These Founder F0 injected embryos were raised to adulthood and incrossed to identify transgenic founders. We identified 10 founder lines that expressed d2EGFP within regions of known FGF activity in the developing embryo. Four lines exhibited strong expression throughout development and were maintained. Tg(Dusp6:d2EGFP)pt6 was used predominantly in this study.

For quantitative mRNA measurements on the NanoString platform46 , we used four nCounter Reporter CodeSets. (i.) A custom CodeSet was used for monitoring gene expression in the Eμ-myc model (Supplementary Table 4, Fig. 2f), for which we selected 754 genes (among which 458 were bound at their promoter by Myc in T) covering the whole expression range and regulatory patterns seen by RNA-seq, including 25 genes classified as non expressed and 5 housekeeping genes (Crocc, Sdha, Tbp, Tubb1, Tubb4). (ii.) A custom CodeSet was used for monitoring gene expression in 3T9 c-mycf/f cells (Supplementary Table 5, Fig. 3f), with 446 genes covering the whole expression range mapped by RNA-seq in 3T9MycER fibroblasts, and including 30 Myc-dependent serum response (MDSR) genes and 20 Myc-independent serum response (MISR) genes8 (link). (iii.) A custom CodeSet was used for monitoring MycER-responsive genes in 3T9MycER cells (Fig. 3d). This CodeSet includes the following 55 genes: Arntl, Ddx58, Olfml2b, Ypel5, Lasp1, Vwa5a, Hsd17b11, Clec2d, Ctso, Prmt2, Myc, Capg, Crocc, Ubb, Dusp6, Rplp0, Car12, Tbp, Mycn, Cdca7l, Hpdl, Ifrd2, Hapln4, Efna3, Polr1b, Slc16a1, Slc19a1, Elovl4, Tfrc, Nnolc1, Wdr73, Zc3h8, Polr3g, Adi1, Fam136a, Bzw2, Wdr55, Taf4b, Mars2, Rrp9, Rragb, Slc25a33, Pdxp, Ica1, Smpdl3b, Dyrk3, Dgat2, GluI, Ifi30, Nr1d1, Reep6, Slc38a3, St6galnac4, Ankrd6, Smtnl2.

A pre-designed NanoString CodeSet, the Human Cancer Reference Kit (GXA-CR1), was used for the experiments with P493-6 cells (Extended Data Fig. 6c).
Dedicated nCounter software was used for data analysis, and raw counts were normalized on the geometric mean of the internal positive control probes included in each CodeSet. Data were plotted either without further normalization, or normalized to cell equivalents (based on the total RNA recovered per cell in each single sample).

Animals were bred and handled as recommended by European Community guidelines. Experiments were performed in accordance with the guidelines of the French Veterinary Department and conducted on 8–12-wk-old mice. Myf5Cre/ROSA26-YFP mice were obtained by crossing the knockin Myf5Cre mice (this strain expresses Cre recombinase from the endogenous Myf5 locus; Tallquist et al., 2000 (link)) with the ROSA26-YFP reporter mice (these R26-stop-EYFP mutant mice have a loxP-flanked STOP sequence followed by the EYFP inserted into the Gt(ROSA)26Sor locus; when bred to mice expressing Cre recombinase, the STOP sequence was deleted and EYFP expression was observed in the cre-expressing tissues of the double mutant offspring; Srinivas et al., 2001 (link)). Six1KO mice were obtained by crossing the Tg:Pax7CreERT2 driver mice (in this strain, the mouse Pax7 promoter drives expression of a Cre recombinase fused with a mutated ligand-binding domain of the human estrogen receptor (ERT2). Upon the introduction of the drug TM, the Cre-ERT2 construct is able to penetrate the nucleus and induce targeted mutation in skeletal muscle SCs (Mourikis et al., 2012 (link)) with the Six1-LoxP line (these mice possess loxP sites on either side of exon 1 of the Six1 gene; when these mutant mice were bred to mice that express Cre recombinase, the resulting offspring will have exon 1 deleted in the Cre-expressing tissue; Fig. S1) backcrossed on C57BL/6 background. Dusp6-null mice (homozygous Dusp6 targeted mutant mice) were on a C57BL/6*SV129 mixed background (Maillet et al., 2008 (link)) and Erk1-null mice (homozygous Erk1 targeted mutant mice; provided by M.
